jQuery Forum

someone who can answer me about this please?

The biggest issue we've noticed to date (and please take note, IE9 is currently preview release, not yet beta which is when we start active testing of browsers) is that mouse drag interactions start very briefly (just an instant) and then get cancelled right away. This has the appearance of no jQuery UI drag-and-drop mouse interactions (drag, drag-and-drop, resize, select, sort) working at all in the latest preview release of IE9.

The issue is caused by some detection code in jQuery UI that, if the browser is IE, checks the value of event.button in the mousemove event. In versions of IE previous to IE9 this property could be used to determine if the mouse button is still down, meaning the user is still dragging. The most common scenario where the inverse could be true is if the mouse button was released during a drag while the cursor was outside of the window, which in the same versions of IE does not trigger a mouseup. So this is detection code to make sure we handle that and don't continue a drag if the mouse button is not still down while the mouse was captured and is still moving.

This change in IE9 actually brings it to standards compliance, so it's hard to fault the browser. The unfortunate bit is that without an update (which we'll have to figure out and release, presumably), current and previous versions of jQuery UI won't support mouse interactions in IE9. As I mentioned above, the soonest we could make such a decision is once the first beta is out.

There's more than that going on, IE9 has moved their old implementation of the event.button over to event.button s (makes sense since their implementation is a bit mask and therefore could theoretically represent more than one button being down). So just in test I checked to see if swapping these values out would solve the issue. which gets it past the "missed mouseup" check but still fails to operate properly

This plugin working in all browesers - ff2+, Opera, Chrome, Safari, ie6, ie7, ie8, but not in IE9.
In IE9 not working. Why?
I think these two problems are connected.

Hi,

I am also facing issues with jquery sortable in new IE9 beta version. I couldn't drag and drop any items using JQuery sortable function. It will be helpful if any one can share a fix for this.

Thanks,

This fix doesn't works with jquery-1.3.2 and jquery-ui 1.7.3 (default in drupal 6 with jquery-update module).
On firebug I get the next error: "TypeError: $.ui.mouse.prototype is undefined."
In explorer: "Unable to get value of the property '_mouseMove': object is null or undefined"

Please, advice how to fix this.

Thanks.

FYI - we have the same problem as oferc666.  We need a patch for 1.3.2/1.7.2 if possible.

I was experiencing the same and had to upgrade to 1.8.6

Please note that the hot fix for older versions of JQuery UI doesn't work. At least it didn't work for versions 1.7 and 1.7.3. To make it work for these versions I had to make the change directly to the jquery-ui.js file. 

Still need a fix for 1.7.2 the above example does not work for that version :(

the fix from ignaciogros above works for me on jquery 1.3.2 and ui 1.7.2

i edited mouseMove function in jquery-ui-1.7.2.js and replaced this:

if ($.browser.msie && !e.button)

with

if ($.browser.msie && document.documentMode < 9 && !e.button)

I've wasted the past few hours, trying to get draggable to work with JQuery 1.8.3 and JQuery UI 1.9.2.

Hi ignaciogr,

Thanks Dude. your code  "if ($.browser.msie && !e.button)
by
if ($.browser.msie && document.documentMode < 9 && !e.button)
in ui.core.js (mouseMove function)" is working fine.

it is very helpful to fix this problem.
