IE issue

FYI:
I'm studying the code more carefully, and I notice a little trick you're doing to get the url using an anchor element. While researching that a bit, I found on SO (see below) that there can be a bug in IE8 where the leading slash isn't included (IE not following the standard because the standard came after the implementation, and changing to the standard would break backward compatibility for the browser).

I'm not sure yet if this is a potential bug or not (I see the url is being dis-assembled for later re-assembly), but I thought I should jot the observation in an issue for reference, if we need it.

未指定源文件或测试。首先定位通过锚元素获取 URL、随后将其拆解并重新组装的 JavaScript；将 IE8 的行为与链接的参考资料进行比较。完成的标准是确定开头斜杠的差异是否是实际的 bug；如果是，则覆盖该行为并修复它。
