如何获得“原始"JavaScript 中的 href 内容 [英] How to get "raw" href contents in JavaScript

问题描述

我正在尝试编写一个 GreaseMonkey 脚本，我想在其中找到所有相对链接的链接.在我看来，这样做的方法是将 href 的内容与 /^https?:/// 进行匹配.

I am trying to write a GreaseMonkey script in which I want to find all of the links that are relative links. It seemed to me that the way to do that would be to match the contents of href against /^https?:///.

但我发现当我访问锚点的 href 属性时，它总是被规范化或被加工成包含http"的形式.也就是说，如果 HTML 包含:

But I find that when I access the anchor's href attribute, it's always normalized or cooked into a form that contains "http". That is, if the HTML contains:

<a id="rel" href="/relative/link">inner</a>

访问

document.getElementById("rel").href

返回

http://example.com/relative/link

如何访问 href 属性中的原始数据?

How can I access the raw data in the href attribute?

或者，有没有更好的方法来查找相关链接?

Alternately, is there a better way to find relative links?

推荐答案

试试getAttribute 方法代替.

Try the getAttribute method instead.
