Javascript compatibility does not work in IE

Question

I have the following code.

function rgb2hex(rgb) {
rgb = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
return "#" + hex(rgb[1]) + hex(rgb[2]) + hex(rgb[3]);
}

It seems to work fine in FF and Chrome. IE has "1", it is null or not an object. The rgb value seems to refer to rgb.match.

Any ideas?

thank

Try printing what rgb is before running a regular expression. It is possible that the input is different.

I assume that you are checking the property dom_element.style. Perhaps IE will never convert this property to format rgb(r, g, b)in the first place.
