删除javascript / jquery中的字符串的一部分？

Question

Let's say I have something like this:

var location = '/users/45/messages/current/20/';

and I need to end up with this:

'/45/messages/current/20/'

So, I need to erase the first part of /whatever/

I can use jquery and/or javascript. How would I do it in the best way possible?

Answer 1

To replace everything up to the second slash:

var i = location.indexOf("/", 1); //Start at 2nd character to skip first slash
var result = location.substr(i);

Answer 2

You can use regular expressions, or the possibly more readable

var location = '/users/45/messages/current/20/';
var delim = "/"
alert(delim+location.split(delim).slice(2).join(delim))

Answer 3

Use JavaScript's slice() command. Do you need to parse for where to slice from or is it a known prefix? Depending on what exactly you are parsing for, it may be as simple as use match() to find your pattern.

Answer 4

location.replace("/(whatever|you|want|users|something)/", "");

Answer 5

在字符串中找到“ /”的第二个索引，然后从索引末尾开始。

Answer 6

location.replace(/\/.*?\//, "/");

Answer 7

If you always want to eliminate the first part of a relative path, it's probably simplest just to use regular expressions

var loc = '/users/45/messages/current/20/';
loc.replace(/^\/[^\/]+/,'');

Answer 8

location.replace(/^\/[^\/]+/, '')
