最后使用/获取网址的最后一部分

Question

I'm trying to get the last part of this url:

http://webserver/Foo/login/

the code that I wrote:

var location = window.location.href.split('/').pop();

will return an empty string 'cause after the / there is nothing. I need to get at least the previous part, so in this case, login.

How can I do this?

Answer 1

The solution using String.replace() (used to replace possible / at the end of the string) and String.split() functions:

 var url = 'http://webserver/Foo/login/', last_section = url.replace(/\\/+$/, '').split('/').pop(); console.log(last_section); 

Answer 2

 const getLastPartURL = url => { const parts = url.split('/'); const length = parts.length; return parts[length - 1] == '' ? parts[length - 2] : parts[length - 1] } console.log(getLastPartURL('http://webserver/Foo/login/')) console.log(getLastPartURL('http://webserver/Foo/login')) console.log(getLastPartURL('http://webserver/Foo/')) console.log(getLastPartURL('http://webserver/Foo')) 

Answer 3

This should do the trick:

location.pathname.match(/[^/]*(?=\/*$)/)[0]

Explanation:

• Location.pathname is a string containing an initial '/' followed by the path of the URL .
• String.prototype.match(regexp) returns an array of the matches.
• [^/]* matches anything but a slash , and that zero or more times .
• (?=\\/*$) matches a slash zero or more times at the end of the string , while not including it .
• There is always exactly one match, so we retrieve it with [0] .

Example:

For all these URLs the output is login :

• http://webserver/Foo/login
• http://webserver/Foo/login/
• http://webserver/Foo/login//
