IE opacity setting

Reported by: thomaspreu Owned by: snover

When setting a opacity to a element in IE (e.g. through fadeTo()) all previously applied ms filters are lost.

Suggested solution

jquery-1.4.2.js line 4602 (

style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : opacity;

replace with:

style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : filter+' '+opacity;

This solution is not perfect because if a filter is modified by a script (e.g. obj.filters.item("DXImageTransform.Microsoft.Matrix").M11 = costheta;) those modification will be lost. However everything one can do thorough obj.filters is doable with search & replace & append to as well.

I don't think there is a good solution which would preserve modifications done through obj.filters, the only way it would work is by querying obj.filters for all current values, building a style.filter string with all those found values in it and than apply to but this is way to complicated to add to jQuery, I would guess 100 lines or more (prove me wrong!).
