I wanted to change where the calendar appeared for the datePicker portion of the Grails UI plugin. After a bit of digging, I found it in the InputTagLib.groovy file:
out << """
YAHOO.util.Event.on("${showButtonId}", "click", function() {
var buttonRegion = YAHOO.util.Dom.getRegion('${showButtonId}');
var buttonHeight = buttonRegion.bottom - buttonRegion.top;
var buttonWidth = buttonRegion.right - buttonRegion.left;
var xy = YAHOO.util.Dom.getXY('${showButtonId}');
var newXY = [xy[0] + buttonWidth, xy[1] + buttonHeight];
YAHOO.util.Dom.setXY('${id}_calContainer_c', newXY);
GRAILSUI.${jsid}Panel.show();
if (YAHOO.env.ua.opera && document.documentElement) {
// Opera needs to force a repaint
document.documentElement.className += "";
}
});"""
The position is set on this line:
YAHOO.util.Dom.setXY('${id}_calContainer_c', newXY);
The YAHOO.util.Dom.setXY() method takes two arguments.
The first argument of the setXY method is either the ID of an HTMLElement, or an actual HTMLElement object. The second argument is an array containing two values: [x, y] where x is the distance from the left edge of the document, and y is the distance from the top edge of the document.
Source: http://developer.yahoo.com/yui/examples/dom/setxy.html
So I can easily adjust where the calendar appears by changing the values in the newXY variable that is passed to the setXY method and it works fine.
However, if I resize the page, the calendar positions its top left corner directly under the showButton's bottom left corner. What is it that makes the repositioning happen when the page is resized and how can I resolve it?
EDIT : A little more info:
This happens in the most recent versions of IE, Firefox, and Chrome
If I resize the page and then click the button to show the calendar, the calendar shows in the expected place but it will reposition if I resize the page again once the calendar is open

Scrolling a div that is within a .sortable() container will start dragging the div when you release the scrollbar
In the fiddle, there are 3 different sortables, 1 of them is a scrolling one
http://jsfiddle.net/wnHWH/1/
Bug: click on the scrollbar and drag it up or down to scroll through the content, when you release the mouse, the div starts to drag, which makes it follow your mouse around and there is no way to unstick it without refreshing the page.
You can use .mousemove event of jquery like this:
$('#sortable div').mousemove(function(e) {
width = $(this).width();
limit = width - 20;
if(e.offsetX < width && e.offsetX > limit)
$('#sortable').sortable("disable");
else
$('#sortable').sortable("enable");
});
I have create fiddle that works here http://jsfiddle.net/aanred/FNzEF/. Hope it meets your need.
sortable() can specify a selector for a handle much like draggable() does. Then only the matched elements get the click events. You specify the handle selector like this:
$('#sortable').sortable( {handle : '.handle'});
You already have most of what you need for the rest. The inner div on your overflowing element makes a suitable handle, like this:
<div style="height: 200px;overflow:auto">
<div class="handle" style="height: 300;">
blah
blah
blah
Then you need to restore the sortability of everything else. You'd think you could just give those divs the handle class, but it's looking for children, so you need to wrap all of them like so:
<div><div class="handle">asadf</div></div>
Modified fiddle
Supplement to SubRed's answer:
This worked perfectly for my needs. However, rather than rely on the width of the scrollbar being 20 pixels (as above), I used the code from:
How can I get the browser's scrollbar sizes?
This allows the code to handle different scrollbar widths on different setups. The code is pasted here for convenience:
function getScrollBarWidth ()
{
var inner = document.createElement('p');
inner.style.width = "100%";
inner.style.height = "200px";
var outer = document.createElement('div');
outer.style.position = "absolute";
outer.style.top = "0px";
outer.style.left = "0px";
outer.style.visibility = "hidden";
outer.style.width = "200px";
outer.style.height = "150px";
outer.style.overflow = "hidden";
outer.appendChild (inner);
document.body.appendChild (outer);
var w1 = inner.offsetWidth;
outer.style.overflow = 'scroll';
var w2 = inner.offsetWidth;
if (w1 == w2) w2 = outer.clientWidth;
document.body.removeChild (outer);
return (w1 - w2);
}
I've also used the width value for the height of the scrollbar and modified SubRed's code to suit. This now works with one or both scrollbars.
I also used code from:
Detecting presence of a scroll bar in a DIV using jQuery?
To determine the presence of either scroll bar and adapted the turning on/off of the sortable code accordingly.
Many thanks.
I've installed Datepicker for Bootstrap and its working nicely. But I can't figure out how to use the place method to position the datepicker above the element instead of below. I'm guessing it works similiar to the bootstrap popovers, but I haven't been able to figure it out.
Any suggestions?
The place function just auto places the date picker under your input box. Its not a function that lets you select where you want to place it.
However you can easily override the default functionality of that function with your own custom placement.
Here is an example of that http://jsfiddle.net/G7sWL/19/
All i did copy the original function and add an additional vertical offset of 10 and horizontal offset of 50.
$(function() {
var picker = $('.datepicker').datepicker();
var widget = picker.data('datepicker');
widget.place = function(){ //the original place function
var offset = this.component ? this.component.offset() : this.element.offset();
this.picker.css({
top: offset.top + this.height + 10, // change #1 = added "+10"
left: offset.left +50 // change #2 = added "+50"
});
}
});
From the page:
.datepicker('place')
Updates the date picker's position relative to the element
It only says it updates the position of the picker (which is absolutely positioned on the page), not that you can change its placement.
What I have currently is a very simple div that has a flexcroll scroll bar. This simple div contains some draggable itmes inside of it. My goal is to be able to drag one of the items and and move it about without the flexcroll scroll bar moving.
As it stands right now if I were to drag one of the items below the viewable area the simple div will scroll down. I would like to prevent this.
I'm using jQuery UI for the draggable items. I've already tried using the option "scroll:false" but this does not work for flexcroll.
I'm sorry I don't have any example code, I'm currently away from my work computer.
flexcroll: http://www.hesido.com/web.php?page=customscrollbar
I don't know if you have already resolved this problem. This morning, I have the same problem and I found your post. After that, I have googled a lot to find a solution without any lucky. So finally, I decided to do someting myself, I hope my idea will help you.
After read the Programming Guid, I found that in this version (2.0) of flexcroll, we could register a function for onfleXcroll whose description could be found by searching the keyword "Pseudo-event: onfleXcroll". This is to say that the method will be executed after a scroll is done. So here, what I restore the "top" style with the value before you drag an element.
Here are the code
var $assetswrapper; // This variable indicates the contentwrapper of you div.
var $assetsscrollbar; // This variable indicates the vscroller of you div.
window.onfleXcrollRun = function () { // This method will be executed as soon as the div has been rendered with the help of flexcroll
// You could find these two divs by using firebug, because the top value of these two divs will be changed when we scroll the div which use the class .flexcroll.
$assetswrapper = $('#contentwrapper');
$assetsscrollbar = $('#vscrollerbar');
}
var wrapperTopPosition = 0; // This is used to stock the top value of the wrapperContent before dragging.
var scrollbarTopPosition = 0; // This is used to stock the top value of the scrollbar before dragging.
var dragged; // This is a boolean variable which is used for indicating whether the draggable element has been dragged.
var dropped = false; // This is a boolean variable which used to say whether the draggable element has been dropped.
$('.draggable').draggable({ // you could change .draggable with any element.
start: function (event, ui) {
// Your code here.
wrapperTopPosition = $assetswrapper.position().top;
scrollbarTopPosition = $assetsscrollbar.position().top
dragged = true;
},
stop: function (event, ui) {
// Your code here.
dragged = false;
dropped = true;
}
});
$('your drag div')[0].onfleXcroll = function () { // This method will be called each time when a scroll has been done.
if (dragged) {
$assetswrapper.css('top', wrapperTopPosition);
$assetsscrollbar.css('top', scrollbarTopPosition);
} else {
// Code here is used for keeping the top position as before even though you have dragged an element out of this div for a long time.
// You could test the scrollbar without this piece of code, if you drag an element out of the div for a long time, the scrollbar will keep its position,
// but after you dropped this element and try to scroll the div, then the scrollbar will reach the end of the div. To solve this problem,
// I have introduced the method setScrollPos with the old top position plus 72. 72 here is to set the scroll increment for this scroll, I know
// this value is not fit for any size of windows, but I don't know how to get the scroll-increment automatically.
if (dropped) {
dropped = false;
$('your drag div')[0].fleXcroll.setScrollPos(false, Math.abs(wrapperTopPosition) + 72);
$('your drag div')[0].fleXcroll.setScrollPos(false, Math.abs(wrapperTopPosition) + 72);
}
}
};
I hope this could give you a help if you haven't found any solution yet.
I am implementing drag and drop, user can drag few images and drop them in a div, and I dynamically append a p tag as label to each image once user click on a button.
Currently I meet problem when I have 2 images which is very close to each other (one is on top of another). The appended p tag for the top images will be hidden by the bottom image. I tried to alert the z-index for each dropped image, and found out it is 'auto'. I guess I need to assign a new z-index for each div, but I tried in the function which i append the label, and it dint work as expect:
function generateLabel() {
var current = 5000;
$('#rightframe img').each(function () {
var cImgName = $(this).attr('id');
var width = $(this).width();
// To select the respective div
var temp = "div#" + cImgName;
$.ajax({
url: '/kitchen/generatelabel',
type: 'GET',
data: { containerImgName: cImgName },
async: false,
success: function (result) {
$(temp).append(result);
// I guess the each function loop through each div according to the time it is created, so I try to assign a decreasing z-index
$(temp).css('z-index', current);
current -= 100;
// To select the label for the image
temp += " p";
// Set label width based on image width
$(temp).width(width);
}
});
});
However, what I get is, bottom image which dropped later do NOT hide the label of the image above, but if the above image is dropped after than the bottom image, above image's label is hide by the bottom image.
It's a very specific situation and I hope I do make myself clear...
Hope can get some help here... Appreciate any feedback...
I am so glad that I able to work out a solution for this kinda weird problem. I get to one useful plugin, the jquery-overlaps which check 2 dom whether they are overlapped with each other or not. Then i assign a z-index to the label accordingly.
Just to show my solution here, in case anyone jump into this bottleneck :)
// To assign an increasing z-index to the label
var count = 100;
$('#rightdiv p').each(function () {
// If any label overlaps with the image (used overlaps plugin)
if ($(this).overlaps($('#rightdiv img'))) {
// Increase count (the z-index)
count += 10;
// Set the parent div z-index 1st, if not the label z-index do not have effect
$(this).parent().css('z-index', count);
$(this).css('z-index', count);
}
});
Thanks! :D
I've got a column renderer defined that creates a HTML fragment which contains the ext.qtip attributes to create a quicktip. All works fine, the image renders in the grid cell, when i hover over the image a tooltip with the larger image is shown ... all nice but the quicktip on the bottom row expands beyond the constraints of the panel, is there any way to make it stay inside the panel boundaries?
var thumbRenderer = function(value, meta, record){
var thumbPath = Config.baseUrl + 'images/thumb/' + record.get('filename');
var previewPath = Config.baseUrl + 'images/big/' + record.get('filename');
return String.format('<img src="{0}" ext:qwidth="312" ext:qtip="<img style=\'margin: 2px 0;width:300px;\' src=\'{1}\' />" width="60" class="pic" />', thumbPath, previewPath);
}
You may want to look at the showAt method:
tip.showAt([x,y]);
Where x and y are the respective x and y co-ordinate positions.
EDIT: You can also use the showBy() method on a QuickTip instance:
