    // IE uses filters for opacity
    if ( !jQuery.support.opacity && name === "opacity" ) {
        if ( set ) {
            // IE has trouble with opacity if it does not have layout
            // Force it by setting the zoom level
            style.zoom = 1;

            // Set the alpha filter to set the opacity
            var opacity = parseInt( value, 10 ) + "" === "NaN" ? "" : "alpha(opacity=" + value * 100 + ")";
            var filter = style.filter || jQuery.curCSS( elem, "filter" ) || "";
            style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : opacity;
        }

        return style.filter && style.filter.indexOf("opacity=") >= 0 ?
            (parseFloat( ropacity.exec(style.filter)[1] ) / 100) + "":
            "";
    }

我已经开始扩展这个行为,使css3选择器与多浏览器兼容(使用了很多 Compass framework implements ).
