通过JavaScript正则表达式获取部分URL路径名 [英] Get part of the url pathname via JavaScript regex

问题描述

我有以下网址:

https://www.example.com/article/f/1/test+article

我需要通过JavaScript(纯JavaScript)从网址中获取"1"部分.我知道我可以使用"location.pathname.replace()"来获取它，但是我对正则表达式并不满意.

And I need to get "1" part from the url via JavaScript (pure javascript). I know that I can get it with "location.pathname.replace()" but I'm not good with regex.

更新

仅作说明:" https://www.example.com/article/f/"永不改变，它是不变的.网址中唯一可以更改的部分是"1"(商品ID)和测试商品"(商品名称).而且我想抓住商品编号.

Just for clarification: "https://www.example.com/article/f/" never changes, it's constant. The only part of the url that can change is "1" (article id) and "test article" (article name). And I want to catch the article id.

推荐答案

location.pathname.match(/\/article\/f\/(\d+)/)[1]

我正在尝试匹配/article/f/和该组捕获的至少1位数字(请注意括号). 如果该ID是您路径中的唯一数字，则可以通过以下方式直接获取它:

I'm trying to match /article/f/ and at least 1 digit captured by the group(note the parenthesis). If that id is the single number in your path, you can get it directly by:

location.pathname.match(/\d+/)[0]
