如何使用javascript / jquery从url中提取文件名？ [英] How to pull the file name from a url using javascript/jquery?

问题描述

某个变量可能包含相对路径或绝对路径。无论哪种方式，我需要能够从变量中提取文件名：

A certain variable might contain a relative path or an absolute path. Either way, I need to be able to pull the filename from the variable:

http://www.somesite.com/dir1/dir2/filename.gif
/dir1/dir2/filename.gif

目录结构也是随意的。所以基本上给出了上面的url（使用arbirtrary目录结构）我需要拉'filename.gif'。提前致谢

The directory structure is also arbitrary. So basically given either of the url's above (with arbirtrary directory structure) I need to pull 'filename.gif'. Thanks in advance

推荐答案

var index = yourstring.lastIndexOf("/") + 1;
var filename = yourstring.substr(index);
