使用JavaScript从URL获取文件名 [英] Get filename from URL using JavaScript

问题描述

我有一个脚本可以从URL中获取文件名，但是我有问题.

I have a script that grabs the filename from a URL but I have a problem.

首先，这是到目前为止我得到的:

Firstly, here's what I've got so far:

var img = $('img').attr('src'),
fileName_Index = img.lastIndexOf("/") + 1,
    fileName = img.substr(fileName_Index);

如果URL在文件名后具有?format=foo，则添加该部分.有没有办法删除以问号开头的最后一部分而仅保留文件名?

If the URL was to have ?format=foo after the filename, that part is added. Is there a way to remove the last part starting with the question mark leaving just the filename?

推荐答案

尝试将此行添加到代码示例的末尾:

Try adding this line to the end of your code sample:

fileName = fileName.replace(/[\#\?].*$/,''); // strips hashes, too

在MDN上的String.replace
