Javascript匹配在IE中不起作用 [英] Javascript match doesn't work in IE

问题描述

我有以下代码。

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

似乎在FF和Chrome中正常工作。 IE出现'1'是null或不是对象。 rgb值似乎确实是rgb.match。

Seems to work ok in FF and Chrome. IE comes up with '1' is null or not an object. rgb value does seem to make it to the rgb.match.

任何想法？

Thx

推荐答案

在运行正则表达式之前尝试打印出rgb。可能是输入不同。

Try printing out what rgb is before you run the regex. It might be that the input is different.

我假设您正在检查 dom_element.style property。也许IE从未将该属性转换为 rgb（r，g，b）格式。

I'm assuming you're checking an dom_element.style property. Perhaps IE never converts that property to the rgb(r, g, b) format in the first place.
