Inserting a line after the workaround for but 3736:

alert( "index: " + index +

" @0:" + this.values(0) + " @1:" + this.values(1) );


index: undefined @0:-65 @1:50

It appears the function normValueFromMouse is returning a value of -65115 when it should return 50 (when clicking on the right-most slider whose value is 50 and left-most slider whose value is -65).

Line 432: valueMouse = this._valueMin() + percentMouse * valueTotal;

valueMouse should be 48, but it is -65115.

I changed the following lines to use parseInt:

_valueMin: function() {

return parseInt( this.options.min );


_valueMax: function() {

return parseInt( this.options.max );


I think negative values were treated as strings, when added as follows:

$.each( data, function( index, value ) {


'<option value="' + value + '">' + value + '</option>' );

Also, the source code comment in the documentation for the UI Slider should begin with "/*!" not "/*" (i.e., append a bang) to preserve the copyright information in the minified version. *OR* remove the bang from everywhere else. Either way, it should be consistent. And this should be in a different bug. ;-)
