获取链接网址的特定部分 [英] Get specific part of url of a link

问题描述

我想获取页面上链接的第三个和第四个斜杠之间的网址的特定部分。

I want to get a specific part of a url between the third and fourth slashes of a link on the page.

编辑：对不起我不认为我很清楚第一次，我的意思是在网页上找到网址链接的特定部分。

Sorry I don't think I was clear the first time, I meant getting the specific part of the url OF A LINK found on the page.

推荐答案

var getSegment = function (url, index) {
   return url.replace(/^https?:\/\//, '').split('/')[index];
}

用法：

getSegment("http://domain.com/a/b/c/d/e", 4); // "d"

replace 确保协议后的前两个斜杠（ http 或 https ）不要数。

The replace makes sure that the first two slashes after the protocol (http or https) don't count.
