如何选择直到并包括第 3 个斜线 (RegExp) 的所有内容? [英] How to Select everything up to and including the 3rd slash (RegExp)?

问题描述

在第 3 个斜杠之前选择所有的最简单的 RegExp 是什么?

What would be the easiest RegExp selecting all before the 3rd slash?

我试过了:

([^/?#]+){3}(?:.*?/)

但它并不像我希望的那样工作.更重要的是我不知道它会在 Google Analytics(过滤器部分)中工作

But it does not work exactly as I would hope it would do. What's more I don't know that it will work in Google Analytics (Filter Section)

我希望它匹配:

1. /
2. /news/
3. /news/details/

除此之外的所有东西(在第三个斜线之后)都不是我想要的

Everything more than this (after the 3rd slash) is not what I want to get
