#9745 closed bug (invalid)

IE8 fx.step._default method causes "Invalid argument" error

Line 8498 triggers an error under certain conditions in IE8 only (works in IE7).

There is a call to fx.now, which is never executed and returns a function object (not a value). When this value returns, it gets concatenated with fx.unit and is assigned to the specified property of fx.elem.style. IE8 doesn't recognize this property and throws an error.

In my case, I have a combination of jQuery, Fancybox, jCarousel, and several degrees of Ajax communication occurring. Fancybox is being applied to DIV elements. When Fancybox is triggered (via onClick), it opens in IE8 but fails when attempting to load the content.

How I fixed this issue:

I modified the _default method to be the following. This seems to work in all browsers, including IE8:

		_default: function( fx ) {
			var now = fx.now();
			if ( fx.elem.style && fx.elem.style[ fx.prop ] != null ) {
				fx.elem.style[ fx.prop ] = (fx.prop === "width" || fx.prop === "height" ? Math.max(0, now) : now) + fx.unit;
			} else {
				fx.elem[ fx.prop ] = now;

we had same IE problem here at www.archive.org, using mwEmbed A/V player. mwEmbed fixed it with this line change for us:

< if ( fx.elem.style && fx.elem.style[ fx.prop ] != null ) {

if ( fx.elem.style && fx.elem.style[ fx.prop ] != null && fx.elem.style[ fx.prop ] != 'relative' && fx.prop != 'position' ) {
