I understand that mobile safari has a lot of bugs around fixed elements, but for the most part I've managed to get my layout working correctly until I added a much needed text input to the fixed navigation at the bottom. Now when the user focuses on the text input element and the virtual keyboard appears, my navigation, which is otherwise always fixed at the bottom of the page, jumps up to a really strange spot in the middle of the page.
I'd add some of my code to this post, but I wouldn't be sure where to start. That navigation is fixed at the bottom and positioned to the left and bottom 0, and 100% width. From there, I don't know what's going on, I can only assume it's a mobile safari bug.
It also appears to lose it's position fixed and become relative, only while the text input element is focused on and the virtual keyboard is open.
http://dansajin.com/2012/12/07/fix-position-fixed/ this is one of the solutions proposed. Seems worth a shot.
In short: set fixed elements to position:absolute when any input is focused and reset them when that element is blurred
.header {
position: fixed;
}
.footer {
position: fixed;
}
.fixfixed .header,
.fixfixed .footer {
position: absolute;
}
and
if ('ontouchstart' in window) {
/* cache dom references */
var $body = $('body');
/* bind events */
$(document)
.on('focus', 'input', function() {
$body.addClass('fixfixed');
})
.on('blur', 'input', function() {
$body.removeClass('fixfixed');
});
}
The solutions on the top are some ways to go and fix the problem, but I think adding extra css class or using moderniz we are complicating things.If you want a more simple solution, here is a non-modernizr non-extra-css but pure jquery solution and work on every device and browsers I use this fix on all my projects
if ('ontouchstart' in window) {
$(document).on('focus', 'textarea,input,select', function() {
$('.navbar.navbar-fixed-top').css('position', 'absolute');
}).on('blur', 'textarea,input,select', function() {
$('.navbar.navbar-fixed-top').css('position', '');
});
}
I had a similar problem, but I found a workaround by adding the following css class to the body element on input focus and then removing it again on unfocus:
.u-oh {
overflow: hidden;
height: 100%;
width: 100%;
position: fixed;
}
Taking from what sylowgreen did, the key is to fix the body on entering the input. Thus:
$("#myInput").on("focus", function () {
$("body").css("position", "fixed");
});
$("#myInput").on("blur", function () {
$("body").css("position", "static");
});
Add javascript like this:
$(function() {
var $body;
if ('ontouchstart' in window) {
$body = $("body");
document.addEventListener('focusin', function() {
return $body.addClass("fixfixed");
});
return document.addEventListener('focusout', function() {
$body.removeClass("fixfixed");
return setTimeout(function() {
return $(window).scrollLeft(0);
}, 20);
});
}
});
and add class like this:
.fixfixed header{
position: absolute;
}
you can reference this article: http://dansajin.com/2012/12/07/fix-position-fixed/
I really like the solution above. I packaged it up into a little jQuery plugin so I could:
Set which parent gets the class
Set which elements this applies to (don't forget "textarea" and "select").
Set what the parent class name is
Allow it to be chained
Allow it to be used multiple times
Code example:
$.fn.mobileFix = function (options) {
var $parent = $(this),
$fixedElements = $(options.fixedElements);
$(document)
.on('focus', options.inputElements, function(e) {
$parent.addClass(options.addClass);
})
.on('blur', options.inputElements, function(e) {
$parent.removeClass(options.addClass);
// Fix for some scenarios where you need to start scrolling
setTimeout(function() {
$(document).scrollTop($(document).scrollTop())
}, 1);
});
return this; // Allowing chaining
};
// Only on touch devices
if (Modernizr.touch) {
$("body").mobileFix({ // Pass parent to apply to
inputElements: "input,textarea,select", // Pass activation child elements
addClass: "fixfixed" // Pass class name
});
}
I use this jQuery script:
var focus = 0;
var yourInput = $(".yourInputClass");
yourInput.focusin(function(){
if(!focus) {
yourInput.blur();
$("html, body").scrollTop($(document).height());
focus = 1;
}
if(focus) {
yourInput.focus();
focus = 0;
}
});
Works perfectly for me.
The focusin and focusout events seem to be better suited to this problem than the focus and blur events since the former bubble up to the root element. See this answer on SO.
Personally I use AngularJS, so I implemented it like this:
$window.document.body.addEventListener('focusin', function(event) {
var element = event.target;
var tagName = element.tagName.toLowerCase();
if(!$rootScope.inputOverlay && (tagName === 'input' || tagName === 'textarea' || tagName === 'select')) {
$rootScope.$apply(function() {
$rootScope.inputOverlay = true;
});
}
});
$window.document.body.addEventListener('focusout', function() {
if($rootScope.inputOverlay) {
$rootScope.$apply(function() {
$rootScope.inputOverlay = false;
});
}
});
Note: I am conditionally running this script if this is mobile Safari.
I put an ng-class attribute on my navbar:
<div class="navbar navbar-default navbar-fixed-top" ng-class="{'navbar-absolute': inputOverlay}">
using the following CSS:
.navbar-absolute {
position: absolute !important;
}
You can read more about focusin here and focusout here.
Test this one. It works. I just test it.
$(document).on('focus','input', function() {
setTimeout(function() {
$('#footer1').css('position', 'absolute');
$('#header1').css('position', 'absolute');
}, 0);
});
$(document).on('blur','input', function() {
setTimeout(function() {
$('#footer1').css('position', 'fixed');
$('#header1').css('position', 'fixed');
}, 800);
});
None of these solutions worked for me because my DOM is complicated and I have dynamic infinite scroll pages, so I had to create my own.
Background: I am using a fixed header and an element further down that sticks below it once the user scrolls that far down. This element has a search input field. In addition, I have dynamic pages added during forward and backwards scroll.
Problem: In iOS, anytime the user clicked on the input in the fixed element, the browser would scroll all the way to the top of the page. This not only caused undesired behavior, it also triggered my dynamic page add at the top of the page.
Expected Solution: No scroll in iOS (none at all) when the user clicks on the input in the sticky element.
Solution:
/*Returns a function, that, as long as it continues to be invoked, will not
be triggered. The function will be called after it stops being called for
N milliseconds. If `immediate` is passed, trigger the function on the
leading edge, instead of the trailing.*/
function debounce(func, wait, immediate) {
var timeout;
return function () {
var context = this, args = arguments;
var later = function () {
timeout = null;
if (!immediate) func.apply(context, args);
};
var callNow = immediate && !timeout;
clearTimeout(timeout);
timeout = setTimeout(later, wait);
if (callNow) func.apply(context, args);
};
};
function is_iOS() {
var iDevices = [
'iPad Simulator',
'iPhone Simulator',
'iPod Simulator',
'iPad',
'iPhone',
'iPod'
];
while (iDevices.length) {
if (navigator.platform === iDevices.pop()) { return true; }
}
return false;
}
$(document).on("scrollstop", debounce(function () {
//console.log("Stopped scrolling!");
if (is_iOS()) {
var yScrollPos = $(document).scrollTop();
if (yScrollPos > 200) { //200 here to offset my fixed header (50px) and top banner (150px)
$('#searchBarDiv').css('position', 'absolute');
$('#searchBarDiv').css('top', yScrollPos + 50 + 'px'); //50 for fixed header
}
else {
$('#searchBarDiv').css('position', 'inherit');
}
}
},250,true));
$(document).on("scrollstart", debounce(function () {
//console.log("Started scrolling!");
if (is_iOS()) {
var yScrollPos = $(document).scrollTop();
if (yScrollPos > 200) { //200 here to offset my fixed header (50px) and top banner (150px)
$('#searchBarDiv').css('position', 'fixed');
$('#searchBarDiv').css('width', '100%');
$('#searchBarDiv').css('top', '50px'); //50 for fixed header
}
}
},250,true));
Requirements: JQuery mobile is required for the startsroll and stopscroll functions to work.
Debounce is included to smooth out any lag created by the sticky element.
Tested in iOS10.
I wasn't having any luck with the solution proposed by Dan Sajin. Perhaps the bug has changed since he wrote that blog post, but on iOS 7.1, the bug will always surface when the position is changed back to fixed after the input is blurred, even if you delay until the software keyboard is hidden completely. The solution I came to involves waiting for a touchstart event rather than the blur event since the fixed element always snaps back into proper position when the page is scrolled.
if (Modernizr.touch) {
var $el, focused;
$el = $('body');
focused = false;
$(document).on('focus', 'input, textarea, select', function() {
focused = true;
$el.addClass('u-fixedFix');
}).on('touchstart', 'input, textarea, select', function() {
// always execute this function after the `focus` handler:
setTimeout(function() {
if (focused) {
return $el.removeClass('u-fixedFix');
}
}, 1);
});
}

The following error just occurs in IE8.
Demo: http://tinyw.in/BLrg
Click on show at Newsletter 313. If you now hover over the blue bar at the left, a layer slides out containing some elements. You can drag each one of this elements. If you start dragging the layer slides back. As you see, in IE8, the dragged element also gets hidden or if you directly drag it over it might get added instantly. And that's the problem, you can open it in IE9, Firefox, Chrome and it works. To see, how it should actually work.
Here's the code which can be found in logic.frontend.js:
(Just a part which is actually used)
$( ".draggable li table" ).draggable({
connectToSortable: ".sortable",
helper: 'clone',
revert: 'invalid',
appendTo: 'body',
start: function(ui) {
$('#elementsContainer').hide('slide', {
direction: "left"
}, 500);
}
});
var height = $('#elementsContainer').outerHeight();
$('#elementsContainerHandle').css('height', height);
$('#elementsContainerHandle').mouseenter(function() {
$('#elementsContainer').css('visibility', 'visible');
$('#elementsContainer').show('slide', { direction: "left" }, 500);
});
$('#elementsContainer').mouseenter(function() {
$(this).css('visibility', 'visible');
});
$('#elementsContainer').mouseleave(function() {
$(this).css('visibility', 'hidden');
});
The problem is, that #elementsContainer gets hidden and due to that all it's children including the dragged element are getting hidden as well. In other browser, .hide() doesn't affect the dragged element because of the option appendTo : 'body'. But in IE8, this seems to break somehow although I'm quite sure the element gets added to the body. I've tried making the draggable visible again with css, .show() etc. but i didn't get it.
Thanks
I have a jQuery UI droppable element which I would like to get bigger when a draggable is hovered over it. I have tried both using the hoverClass option and also binding to the drophover event.
Visually, both these methods work fine. However, once the draggable exits the original (smaller) boundary of the droppable, jQuery UI interprets this as a 'dropout', despite still being within the current (larger) boundary.
For example, js:
$("#dropable").droppable({
hoverClass: 'hovering'
}.bind('dropout', function () {console.log('dropout')});
css:
#droppable { background: teal; height: 10px; }
#droppable.hovering { height: 200px; }
In this case, when a draggable hovers over the droppable, the droppable visually increases in size to 200px. If at this point, the draggable is moved down by 20px, I would expect it to still be hovering over the droppable. Instead, jQuery UI fires the dropout event and the droppable reverts to being 10px high.
Anyone know how to get it to behave in the way I'd expect it to?
jsFiddle example: http://jsfiddle.net/kWFb9/
Had the same problem, I was able to solve it by using the following options:
$("#droppable").droppable({
hoverClass: 'hovering',
tolerance: 'pointer'
});
$('#draggable').draggable({
refreshPositions: true
});
Here's the working fiddle: http://jsfiddle.net/kWFb9/51/
See http://bugs.jqueryui.com/ticket/2970
So I made a couple tweaks to your fiddle
First I set the droppable tolerance to "touch" which will activate whenever any part of the draggable is touching it. This causes the hovering class to be applied.
Next I added an animation to resize your draggable element slightly. I wasn't sure if this was functionality you wanted or not so I put it in there anyways.
Lastly, I permanently apply the hovering class to the droppable element when the draggable element is dropped into the droppable zone. This way the droppable doesn't revert to that narrow height when there is an element in it
http://jsfiddle.net/kWFb9/2/
EDIT:
Better fiddle: http://jsfiddle.net/kWFb9/6/
I hope this helps :)
you could create a bigger (i.e. the size of #droppable.hovering) div without background and apply your droppable to it. Note that you didn't provide HTML but the new #drop_container should contain both divs.
JS
var dropped;
$("#droppable").droppable({
drop: function(event, ui) {
dropped = true;
}
});
$('#draggable').draggable({
start: function(event, ui) {
$("#droppable").addClass("hovering");
dropped = false;
},
stop: function(event, ui) {
if (!dropped) {
$("#droppable").removeClass("hovering");
}
}
});
CSS
#droppable { background: teal; height: 10px; }
#droppable.hovering, #drop_container { height: 200px; }
Or you could try another solution with .live() or .livequery() from this article
[EDIT] I've edited my code and here is a jsfiddle: http://jsfiddle.net/94Qyc/1/
I had to use a global var, I didn't find a better way to check wether the box was dropped. If anybody has an idea, that would be great.
There is an other (hum hum) not bad solution :
TL;DR: Fiddle
The problem is that the plugin stores dom element's size values when the widget is created (something like) :
//jquery.ui.dropable.js
$.widget("ui.droppable", {
...
_create: function() {
var proportions,
this.proportions = function() { return proportions; }
And the offset for widgets are initialized in $.ui.ddmanager.prepareOffsets();
So we only need to overwrite the proportions object.
This way allow to access to real plugin properties so we can write something like :
$("#droppable").droppable({
hoverClass: 'hovering',
over: function(ev, ui) {
var $widget = $(this).data('droppable');
$widget.proportions = {
width: $(this).width(),
height: $(this).height()
};
},
out: function(ev, ui) {
var $widget = $(this).data('droppable'); //ui-droppable for latests versions
$widget.proportions = {
width: $(this).width(),
height: $(this).height()
};
}
})
I'm working on a browser based app, currently I'm developing and styling for the ipad safari browser.
I'm looking for two things on the ipad: How can I disable vertical scrolling for pages that don't require it? & how can I disable the elastic bounce effect?
This answer is no longer applicable, unless you are developing for a very old iOS device... Please see other solutions
2011 answer: For a web/html app running inside iOS Safari you want something like
document.ontouchmove = function(event){
event.preventDefault();
}
For iOS 5 you may want to take the following into account: document.ontouchmove and scrolling on iOS 5
Update September 2014:
A more thorough approach can be found here: https://github.com/luster-io/prevent-overscroll. For that and a whole lot of useful webapp advice, see http://www.luster.io/blog/9-29-14-mobile-web-checklist.html
Update March 2016: That last link is no longer active - see https://web.archive.org/web/20151103001838/http://www.luster.io/blog/9-29-14-mobile-web-checklist.html for the archived version instead. Thanks #falsarella for pointing that out.
You can also change the position of the body/html to fixed:
body,
html {
position: fixed;
}
To prevent scrolling on modern mobile browsers you need to add the passive: false. I had been pulling my hair out getting this to work until I found this solution. I have only found this mentioned in one other place on the internet.
function preventDefault(e){
e.preventDefault();
}
function disableScroll(){
document.body.addEventListener('touchmove', preventDefault, { passive: false });
}
function enableScroll(){
document.body.removeEventListener('touchmove', preventDefault);
}
You can use this jQuery code snippet to do this:
$(document).bind(
'touchmove',
function(e) {
e.preventDefault();
}
);
This will block the vertical scrolling and also any bounce back effect occurring on your pages.
overflow: scroll;
-webkit-overflow-scrolling: touch;
On container you can set bounce effect inside element
Source: http://www.kylejlarson.com/blog/2011/fixed-elements-and-scrolling-divs-in-ios-5/
I know this is slightly off-piste but I've been using Swiffy to convert Flash into an interactive HTML5 game and came across the same scrolling issue but found no solutions that worked.
The problem I had was that the Swiffy stage was taking up the whole screen, so as soon as it had loaded, the document touchmove event was never triggered.
If I tried to add the same event to the Swiffy container, it was replaced as soon as the stage had loaded.
In the end I solved it (rather messily) by applying the touchmove event to every DIV within the stage. As these divs were also ever-changing, I needed to keep checking them.
This was my solution, which seems to work well. I hope it's helpful for anyone else trying to find the same solution as me.
var divInterval = setInterval(updateDivs,50);
function updateDivs(){
$("#swiffycontainer > div").bind(
'touchmove',
function(e) {
e.preventDefault();
}
);}
Code to To remove ipad safari: disable scrolling, and bounce effect
document.addEventListener("touchmove", function (e) {
e.preventDefault();
}, { passive: false });
If you have canvas tag inside document, sometime it will affect the usability of object inside Canvas(example: movement of object); so add below code to fix it.
document.getElementById("canvasId").addEventListener("touchmove", function (e) {
e.stopPropagation();
}, { passive: false });
none of the solutions works for me. This is how I do it.
html,body {
position: fixed;
overflow: hidden;
}
.the_element_that_you_want_to_have_scrolling{
-webkit-overflow-scrolling: touch;
}
Try this JS sollutuion:
var xStart, yStart = 0;
document.addEventListener('touchstart', function(e) {
xStart = e.touches[0].screenX;
yStart = e.touches[0].screenY;
});
document.addEventListener('touchmove', function(e) {
var xMovement = Math.abs(e.touches[0].screenX - xStart);
var yMovement = Math.abs(e.touches[0].screenY - yStart);
if((yMovement * 3) > xMovement) {
e.preventDefault();
}
});
Prevents default Safari scrolling and bounce gestures without detaching your touch event listeners.
Tested in iphone. Just use this css on target element container and it will change the scrolling behaviour, which stops when finger leaves the screen.
-webkit-overflow-scrolling: auto
https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-overflow-scrolling
improved answer #Ben Bos and commented by #Tim
This css will help prevent scrolling and performance issue with css re-render because position changed / little lagging without width and height
html,
body {
position: fixed;
width: 100%;
height: 100%
}
For those who are using MyScript the Web App and are struggling with the body scrolling/dragging (on iPad and Tablets) instead of actually writing:
<body touch-action="none" unresolved>
That fixed it for me.
You can use js for prevent scroll:
let body = document.body;
let hideScroll = function(e) {
e.preventDefault();
};
function toggleScroll (bool) {
if (bool === true) {
body.addEventListener("touchmove", hideScroll);
} else {
body.removeEventListener("touchmove", hideScroll);
}
}
And than just run/stop toggleScroll func when you opnen/close modal.
Like this toggleScroll(true) / toggleScroll(false)
(This is only for iOS, on Android not working)
Try this JS solution that toggles webkitOverflowScrolling style. The trick here is that this style is off, mobile Safari goes to ordinary scrolling and prevents over-bounce — alas, it is not able to cancel ongoing drag. This complex solution also tracks onscroll as bounce over the top makes scrollTop negative that may be tracked. This solution was tested on iOS 12.1.1 and has single drawback: while accelerating the scroll single over-bounce still happens as resetting the style may not cancel it immediately.
function preventScrollVerticalBounceEffect(container) {
setTouchScroll(true) //!: enable before the first scroll attempt
container.addEventListener("touchstart", onTouchStart)
container.addEventListener("touchmove", onTouch, { passive: false })
container.addEventListener("touchend", onTouchEnd)
container.addEventListener("scroll", onScroll)
function isTouchScroll() {
return !!container.style.webkitOverflowScrolling
}
let prevScrollTop = 0, prevTouchY, opid = 0
function setTouchScroll(on) {
container.style.webkitOverflowScrolling = on ? "touch" : null
//Hint: auto-enabling after a small pause makes the start
// smoothly accelerated as required. After the pause the
// scroll position is settled, and there is no delta to
// make over-bounce by dragging the finger. But still,
// accelerated content makes short single over-bounce
// as acceleration may not be off instantly.
const xopid = ++opid
!on && setTimeout(() => (xopid === opid) && setTouchScroll(true), 250)
if(!on && container.scrollTop < 16)
container.scrollTop = 0
prevScrollTop = container.scrollTop
}
function isBounceOverTop() {
const dY = container.scrollTop - prevScrollTop
return dY < 0 && container.scrollTop < 16
}
function isBounceOverBottom(touchY) {
const dY = touchY - prevTouchY
//Hint: trying to bounce over the bottom, the finger moves
// up the screen, thus Y becomes smaller. We prevent this.
return dY < 0 && container.scrollHeight - 16 <=
container.scrollTop + container.offsetHeight
}
function onTouchStart(e) {
prevTouchY = e.touches[0].pageY
}
function onTouch(e) {
const touchY = e.touches[0].pageY
if(isBounceOverBottom(touchY)) {
if(isTouchScroll())
setTouchScroll(false)
e.preventDefault()
}
prevTouchY = touchY
}
function onTouchEnd() {
prevTouchY = undefined
}
function onScroll() {
if(isTouchScroll() && isBounceOverTop()) {
setTouchScroll(false)
}
}
}
Consider the following architecture:
<body> <div id="root"></div> </body>
this css will work:
#root { position: fixed; height: 100%; overflow: auto; }
For those of you who don't want to get rid of the bouncing but just to know when it stops (for example to start some calculation of screen distances), you can do the following (container is the overflowing container element):
const isBouncing = this.container.scrollTop < 0 ||
this.container.scrollTop + this.container.offsetHeight >
this.container.scrollHeight
Disable safari bounce scrolling effect:
html,
body {
height: 100%;
width: 100%;
overflow: auto;
position: fixed;
}
I had an issue with grabbing the html element in the background, when a menu with scroll was open and either at the top or at the bottom at the scroll height. I tried lots of things. Setting html position to fixed was the closest I got to lock the screen, but in the PWA it resulted in a white area at the bottom, that I couldn't fix.
Finally I've found a solution, that worked for me 🎉:
html {
width: 100%;
height: 100%;
overflow: hidden;
}
body {
margin: 0;
height: calc(100vh - 1px)
overflow: hidden;
background-color: 'Whatever color you need to hide the 1px at the bottom'
}
Because it only seems to be an issue on iOS, I have targeted the devices from iPhone X to 12 Pro Max:
body {
margin: 0;
overflow: hidden;
background-color: '#TIP: You can use the color picker from the inspector';
#media only screen and (min-width: 375px) and (max-height: 926px) and (-webkit-device-pixel-ratio: 3) {
height: calc(100vh - 1px);
}
}
This is preventing any kind of scroll, touch or grab in the html or body elements, and scroll is still working in the menu or where else specified. Cheers.
body {
touch-action:none;
}
Using JQuery
// Disable
$("body").css({ "touch-action": "none" })
// Enable
$("body").css({ "touch-action": "auto" })
css overscroll-behavior is now supported in iOS 16. If you are targeting > iOS 16 devices, to prevent elastic bounce effect, add the following CSS to the html root
html {
overscroll-behavior: none;
}
Please note, the solution provided only disables elastic bounce effect when content is larger than viewport.
If you also want to completely disable scrolling in main page on iOS devices, use
html body {
overflow: hidden;
}
Similar to angry kiwi I got it to work using height rather than position:
html,body {
height: 100%;
overflow: hidden;
}
.the_element_that_you_want_to_have_scrolling{
-webkit-overflow-scrolling: touch;
}
Solution tested, works on iOS 12.x
This is problem I was encountering :
<body> <!-- the whole body can be scroll vertically -->
<article>
<my_gallery> <!-- some picture gallery, can be scroll horizontally -->
</my_gallery>
</article>
</body>
While I scrolling my gallery, the body always scrolling itself (human swipe aren't really horizontal), that makes my gallery useless.
Here's what I did while my gallery start scrolling
var html=jQuery('html');
html.css('overflow-y', 'hidden');
//above code works on mobile Chrome/Edge/Firefox
document.ontouchmove=function(e){e.preventDefault();} //Add this only for mobile Safari
And when my gallery end its scrolling...
var html=jQuery('html');
html.css('overflow-y', 'scroll');
document.ontouchmove=function(e){return true;}
Hope this helps~
I needed the dialog to maintain its position fixed even if the page scrolled, so i used the
extension at http://forum.jquery.com/topic/dialog-position-fixed-12-1-2010 but there's 2 problems with it:
it flickers in IE and Firefox on page scroll (in Safari/Chrome it's fine)
on closing and then reopening, it looses its stickyness and scrolls along with the page.
Here's the code i'm using for creating the dialog:
$('<div id="'+divpm_id+'"><div id="inner_'+divpm_id+'"></div><textarea class="msgTxt" id="txt'+divpm_id+'" rows="2"></textarea></div>')
.dialog({
autoOpen: true,
title: user_str,
height: 200,
stack: true,
sticky: true //uses ui dialog extension to keep it fixed
});
And here's the code i'm using for reopening it:
jQuery('#'+divpm_id).parent().css('display','block');
Suggestions/solutions?
Thanks
I tried some of the solutions posted here, but they don't work if the page has been scrolled prior to the dialog being opened. The problem is that it calculates the position without taking into account the scroll position, because the position is absolute during this calculation.
The solution I found was to set the dialog's parent's CSS to fixed PRIOR to opening the dialog.
$('#my-dialog').parent().css({position:"fixed"}).end().dialog('open');
This assumes that you have already initialized the dialog with autoOpen set to false.
Note, this does not work if the dialog is resizable. It must be initialized with resizing disabled in order for the position to remain fixed.
$('#my-dialog').dialog({ autoOpen: false, resizable: false });
Tested this thoroughly and have found no bugs so far.
I combined some suggested solutions to the following code.
Scrolling, moving and resizing works fine for me in Chrome, FF and IE9.
$(dlg).dialog({
create: function(event, ui) {
$(event.target).parent().css('position', 'fixed');
},
resizeStop: function(event, ui) {
var position = [(Math.floor(ui.position.left) - $(window).scrollLeft()),
(Math.floor(ui.position.top) - $(window).scrollTop())];
$(event.target).parent().css('position', 'fixed');
$(dlg).dialog('option','position',position);
}
});
Update:
If you want to make it default for all dialogs:
$.ui.dialog.prototype._oldinit = $.ui.dialog.prototype._init;
$.ui.dialog.prototype._init = function() {
$(this.element).parent().css('position', 'fixed');
$(this.element).dialog("option",{
resizeStop: function(event,ui) {
var position = [(Math.floor(ui.position.left) - $(window).scrollLeft()),
(Math.floor(ui.position.top) - $(window).scrollTop())];
$(event.target).parent().css('position', 'fixed');
// $(event.target).parent().dialog('option','position',position);
// removed parent() according to hai's comment (I didn't test it)
$(event.target).dialog('option','position',position);
return true;
}
});
this._oldinit();
};
I could not get Scott's answer to work with jQuery UI 1.9.1. My solution is to reposition the dialog in a callback from the open event. First set the css position to fixed. Then position the dialog where you want it:
$('selector').dialog({
autoOpen: false,
open: function(event, ui) {
$(event.target).dialog('widget')
.css({ position: 'fixed' })
.position({ my: 'center', at: 'center', of: window });
},
resizable: false
});
Note: As noted in another answer, resizing the dialog will set its position to absolute again, so I've disabled resizable.
Bsed on Langdons's comment above, I tried the following, which works fine with jQuery-UI 1.10.0 and resizable dialogs:
$('#metadata').dialog(
{
create: function (event) {
$(event.target).parent().css('position', 'fixed');
},
resizeStart: function (event) {
$(event.target).parent().css('position', 'fixed');
},
resizeStop: function (event) {
$(event.target).parent().css('position', 'fixed');
}
});
try:
$(document).ready(function() {
$('#myDialog').dialog({dialogClass: "flora"});
$('.flora.ui-dialog').css({position:"fixed"});
)};
(from http://dev.jqueryui.com/ticket/2848)
Force your dialog box's position to be position:fixed using CSS
$('.selector').dialog({ dialogClass: 'myPosition' });
and define the myPosition css class as:
.myPosition {
position: fixed;
}
$("#myDilog").dialog({
create:function(){
$(this).parent().css({position:"fixed"});
}
});
I found that these answers didn't work for me but combining some of them did.
I used the create function to set the dialog as fixed so it didn't scroll the window down when the dialog was created.
create: function (event) {
$(event.target).parent().css('position', 'fixed')
}
Also I used the open function to make sure the dialog didn't disappear off the screen by changing the top value.
open: function(event, ui) {
$(event.target).parent().css('top', '30%')
}
This worked with autoOpen and resizable.
$('#myDialog').dialog({ dialogClass: "flora" });
$('.flora.ui-dialog').css({ top: "8px" });
this will keep the dialog on top position no matter were we have clicked.
$('#'+tweetidstack.pop()).dialog("open").parent().css({position:"fixed"});
Why use $(document).ready ? This might be a recent development, but it works fine now.
$( ".ui-dialog" ).css("position","fixed");
$( ".ui-dialog" ).css("top","10px");
put this code on open function of dialog
First, create your dialog. Something like this:
$("#dialog_id").dialog({
autoOpen : false,
modal : true,
width: "auto",
resizable: false,
show: 'fade',
hide: { effect:"drop",duration:400,direction:"up" },
position: top,
height: 'auto',
title: "My awesome dialog",
resizeStart: function(event, ui) {
positionDialog();
},
resizeStop: function(event, ui) {
positionDialog();
}
});
$("#dialog_id").dialog('open');
Then make it auto center with this:
function positionDialog (){
setInterval(function(){
if($("#dialog_id").dialog( "isOpen" )){
$("#dialog_id").dialog('option','position',$("#dialog_id").dialog( "option", "position" ));
}
},500);
}
//setInterval is for make it change position "smoothly"
//You can take it off and leave just the if clausule and its content inside the function positionDialog.
The solution is actually really simple. I don't know if this applied when the question was asked but it does now anyway.
//First a container/parent-div with fixed position is needed
var dialogContainer=document.body.appendChild(document.createElement("div"));
dialogContainer.style.position="fixed";
dialogContainer.style.top=dialogContainer.style.left="50%";//helps centering the window
//Now whenever a dialog is to be created do it something like this:
$(myDialogContent).dialog({
appendTo: dialogContainer,
position: {
at: 'center center',
of: dialogContainer
}
});

About "position": http://api.jqueryui.com/position/
While similar to some of the other answers above, I've found that I had to do more than just position: fix the dialog, but I also had to position: static it's content to keep it attached to the dialog.
$('<div id="myDialog" class="myClass">myContent</div>')
.dialog(dialogOptions)
.parent()
.css({ position: 'fixed' })
.end()
.position({ my: 'center', at: 'center', of: window })
.css({ position: 'static' });
After this, I could call .dialog('open') any time I wanted and it would simply appear where I left it. I actually have this in a function that will return the existing dialog or create a new one as needed and then I just change the values of the dialog before .dialog('open') gets called.
As i wrote in my blog https://xbrowser.altervista.org/informatica-portata/jquery-easyui-bug-fix-window-dialog-position-widget/
I've found a bug in “window” element or “dialog” element.
When you instantiate this widget, it go out of the main window browser, in particular in top and left position (when you drag o resize it).
To resolve this problem i’ve implemented this solution.
You can read the source code below:
$(dialog).window({
onMove: function(left, top) {
if (left < 0 || top < 0) {
left = (left < 0) ? 0 : left;
top = (top < 0) ? 0 : top;
$(this).window('move', {left: left, top: top});
}
},
onResize: function(width, height) {
var opt = $(this).window("options");
var top = opt.top;
var left = opt.left;
if (top < 0) {
top = (top < 0) ? 0 : top;
$(this).window('move', {left: left, top: top});
}
}
}).window("open");
The same code is for dialog:
$(dialog).dialog({
onMove: function(left, top) {
if (left < 0 || top < 0) {
left = (left < 0) ? 0 : left;
top = (top < 0) ? 0 : top;
$(this).dialog('move', {left: left, top: top});
}
},
onResize: function(width, height) {
var opt = $(this).window("options");
var top = opt.top;
var left = opt.left;
if (top < 0) {
top = (top < 0) ? 0 : top;
$(this).dialog('move', {left: left, top: top});
}
}
}).dialog("open");
Futhermore, when you call “$(this).window(“options”);” inside “onResize” method, and start your App,
you don’t see the window; so i must insert the “.window(“open”);” at the and of declaration of dialog.
I hope to help you.
