Tutorial Change WMode with jQuery
If you don't set the wmode on a flash embed it will float over the top of an overlay which can be a pretty big deal. This is ideal in environment with lots of legacy video code or where users will be posting new code and teaching them about wmode is a lost cause. This should work in all browsers.
$("embed").attr("wmode", "opaque");
var embedTag;
$("embed").each(function(i) {
embedTag = $(this).attr("outerHTML");
if ((embedTag != null) && (embedTag.length > 0)) {
embedTag = embedTag.replace(/embed /gi, "embed wmode="opaque" ");
$(this).attr("outerHTML", embedTag);
} else {
$(this).wrap("<div></div>");
}
});
