jquery ui dialog fixed positioning - jquery-ui

Question

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

Answer 1

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.

Answer 2

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.

Answer 4

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');
}
});

Answer 5

try:
$(document).ready(function() {
$('#myDialog').dialog({dialogClass: "flora"});
$('.flora.ui-dialog').css({position:"fixed"});
)};
(from http://dev.jqueryui.com/ticket/2848)

Answer 6

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;
}

Answer 7

$("#myDilog").dialog({
create:function(){
$(this).parent().css({position:"fixed"});
}
});

Answer 8

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.

Answer 9

$('#myDialog').dialog({ dialogClass: "flora" });
$('.flora.ui-dialog').css({ top: "8px" });
this will keep the dialog on top position no matter were we have clicked.

Answer 10

$('#'+tweetidstack.pop()).dialog("open").parent().css({position:"fixed"});
Why use $(document).ready ? This might be a recent development, but it works fine now.

Answer 11

$( ".ui-dialog" ).css("position","fixed");
$( ".ui-dialog" ).css("top","10px");
put this code on open function of dialog

Answer 12

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.

Answer 13

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
}
});

Answer 14

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.

Answer 15

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.
