jQuery Bulldozes Other IE Filters When Assigning Opacity

Reported by: Owned by:
Priority: high Milestone: 1.6
Component: css Version: 1.5.1
Keywords: Cc:
Blocked by: Blocking:

Steps to Reproduce:

Assign a background gradient to an element in your external CSS, like so:

filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#ffff0000', EndColorStr='#ffffffff');

On the same element, set a moderate opacity:

$(elem).css('opacity', '0.5');

Your gradient will disappear.

Steps to Fix:

1. Use

to see the full filter list

2. If the Alpha filter isn't already applied, add to the filter list (space- or comma-delimited)

3. If it does exist previously, modify via

elem.filters["DXImageTransform.Microsoft.Alpha"].opacity = Number_between_0_and_100
