如何获得带有正则表达式的最后一段？

Question

I have the following url. 我有以下网址。

I want to get 24 from this to use in jquery/javascript. 我想从中获取24以便在jquery / javascript中使用。

Something like this. 这样的事情。

var id=this.href.replace(/.*=/,'');
this.id='delete_link_'+id;

Could anyone tell me how to code this? 谁能告诉我该如何编码？

Answer 1

var id = this.href.match(/[^\/]*$/)

this.id = 'delete_link_' + id;

Answer 2

Why use regex? 为什么要使用正则表达式？

var parts=this.href.split("/");
var id = parts[parts.length - 1];
this.id='delete_link_'+id;

Answer 3

Regex is overkill here. 正则表达式在这里过大了。

var s = "http://127.0.0.1/ci/index.php/admin/menus/edit/24";
s.substring(s.lastIndexOf("/")+1);

Answer 4

"http://127.0.0.1/ci/index.php/admin/menus/edit/24".match(/^.*\/([^\/]+)$/)[1]
