jQuery Possible exposition of Bug in Cross Browser Event handling

Share on linkedin Share on facebook Share on print Share on gmail Share on pinterest_share Share on mailto Share on delicious More Sharing Services 0

First, I have searched and not found a forum or bug list that gives this detail.

I attached a Slider to a Text Area that is a grouped pair within a Sortable, and it's pretty slickl in Firefox, but then went all goofy in IE (7 and 8).

What I discovered was that the "stop" and "start" events of the slider were propagating to parent in IE, but not in Firefox.

Through research, I discovered that one can manually stop propagation on an event (event.stopPropagation()), but my real observation is that the default behavior is different from these two (common) browsers. For those who have dug deeper in the design, should this be a bug in "Slider" that would implement a default "stop" and "start" that do not propagate events so as to be browser consistent? Or does this expose a larger difference in expectations of "bubbling" between browsers that would perhaps fix many issues? Is there, for instance, a common "default" function that can be added in the lower level code?

(sorry for including code here, but it wouldn't go into Attachments)

Cross browser event handling

I have a document with a parent element that has mousedown,mouseup and mousemove events registered to it. The parent element has some child elements as well. I observe inconsistent behaviours between browser types when I hold the mouse button down, move the pointer and release the button. ie7 - mouseup fires when over a child or parent op9 - mouseup fires only when over the parent ff2 - mouseup fires only over a child or parent but only if the pointer has moved since the mousedown occured I'm new to events - what can I do to get events to fire (or at least capture them) in the order I want.

jQuery Possible Animate Bug

There seems to be an animate bug with jQuery 1.2. Try animating the css left value of a relatively or absolutely positioned element. For instance, I have an object with a css left value of "-880px". When I call .animate( {left:"-1760px"} ,300, function(){ alert( $ (this).css('left')}), the callback will result in "-2640px", not "-1760px" like it should be. The above code worked in version 1.1.2, not 1.2.
jQuery Possible .clone() bug in 1.2.1 on IE6

I use jQuery extensively to help create "repeatable" elements in some forms. After upgrading from 1.1.4 to 1.2.1, I noticed it stopped working. I finally narrowed down the cause to the (dynamically set) name attribute no longer getting cloned correctly. Is this expected behavior in 1.2.1, or a legitimate bug? Wanted to check here before submitting a bug to the tracker. You can see a sample, with all relevant code in-line, here: http://dev.nosq.com/jquery_name_bug/
jQuery Possible Draggable Bug

Hi, We have detected a buggy behavior of draggable.js on our website with Firefox. After digging a bit, we found that it might be related to the "overflow-y: scroll" css property we use on the HTML element to permanently show the vertical scrollbar. Is it a jqueryui bug or a firefox bug ? I've put online a modified copy of the draggable sample page to show the buggy behavior : http://www.mably.com/dev/draggable.html Just reduce the size of your Firefoxbrowser window to activate the vertical scrollbar, scroll down a bit and start dragging. You'll see the draggable objet jump up the page the same amount you've scrolled the page down. For the moment we have temporarily disabled the overflow-y:scroll css property. Any help would be greatly appreciated. FranÃ§ois Masurel Bordeaux, FRANCE
jQuery possible to override inline onchange() event?

I have a select box with an inline "onchange()" event that reloads the page. Using jQuery I've created a $('#myForm select').live('change', function (e){...}) event handler to intercept the onchange() behavior and even though I have e.preventDefault() and e.stopPropagation() after my jquery event runs the inline onchange() is still triggered... Am I missing something here? I realize I could easily remove the onchange() from the code but ideally I shouldn't edit the HTML directly and just override it using jquery...

jQuery Possible Selector Bug?

Everyone, I was just using jQuery 1.3.1 when I came across an issue in IE7.

jQuery IE issue... load order, DOM, event handling... ? help please!

all. I'm working on a site where id like an image to fade in as the page shows up. The tricky part (i think) is that you can't trace the load of a background image. So ive made a new image dynamically and traced that, assuming that once the image is loaded there, i can insert it to the background, and remove the loading icon (#loadingGal) code follows! (function($) { $.fn.pageOpening = function(path) { $("#loadingGal").show(); var imageObj = new Image(); $(imageObj).attr("src",path).load(function(){ $("#loadingGal").hide(); $("#leftCol").hide(); $("#leftCol").css("background-image","url("+path+")").fadeIn(1000); }); } $(document).ready(function() { $().pageOpening("images/photo-green-homes.jpg"); }); In IE6, the background image does not load and the loading div does not hide. On refresh however, all is fine. I feel this is a loading order issue with IE... or maybe cache. any help is appreciated!

3rd party code interference with responsive jquery event handling

I can't imagine my situation is very unique so I must be failing to see the trees through the forest. 1) We have a site that has a number of JQuery style event handlers. By this I mean we use the ready to apply event bindings based on jq selectors. 2) We have 3rd party JS which we have no control over. Some of it has a tendency to load slowly. In addition it depends on document.write. So when the 3rd party code runs slow it delays the JQ ready which means our page is largely rendered, but the event handling is broken. This results in a horrible UX. I can't AJAX load the script and eval it because then then the document.write will produce is content out of the intended context of the DOM. I have been trying to use regular DOM methods to add the script element in the correct location at the end of the JQ ready so it happens after the events are bound without luck so far. Do any of the experienced JQ users have a recommendation on how to handle 3rd party widgets and event binding?
