There're several folks asking for multiple-handle sliderMoveTo on the UI list:

​http://groups.google.com/group/jquery-ui/browse_thread/thread/20db89aaad9836f0#

Kalath e-mailed me off-list and asked about it, and I wrote up a quick patch. It adds an extra parameter to sliderMoveTo which is the (zero-based) index of the handle to move, so to move the 3rd handle to 40 you'd do:

$('#slider').sliderMoveTo(40, null, null, null, 2);

The patch moves most of the body of moveTo() into an inner function that takes the interaction handle, and then calls that function with either this.interaction (single handle) or this.interactions[which] (multiple handles). All the rest of the touched lines are indentation changes or this->self swaps to make the moveTo body work inside an inner function.

It's dependent upon bug #1737. The patches themselves are independent (and both should be applied), but sliderMoveTo doesn't work at all until #1737 is fixed.

I've done some additional demos for the slider widget, mostly as testcases for bugs that I was having, though also to refer back to as I use more functionality. Changes from the current file:

1. Exercises minValue and maxValue (#1865)

2. Shows how to listen for slide events

3. Illustrates sliderMoveTo for both single (#1737) and multiple handles (#1938)

By default, the popup calendar cannot be used in XML pages delivered as application/xhtml+xml under Firefox 2.0 or 3.0. The problem is that the HTML fragment inserted contains HTML entities, which don't work in innerHTML. The calendar throws an "Invalid Entity" exception.

Fortunately, it's an easy fix, backwards compatible, and compatible with any browser that jQuery supports.
