location.pathnamegives you the local part of the url.
location.pathname为您提供网址的本地部分。
var filename = location.pathname.match(/[^\/]+$/)[0]
The above gives you only the very last part. For example, if you are on http://somedomain/somefolder/filename.html, it will give you filename.html
上面只给你最后一部分。例如，如果你在http://somedomain/somefolder/filename.html，它会给你filename.html

var full = location.pathname;
var path = full.substr(full.lastIndexOf("/") + 1);

For this page if you inspect the window.locationobject you will see
对于此页面，如果您检查window.location对象，您将看到
hash:
host: stackoverflow.com
hostname: stackoverflow.com
href: http://stackoverflow.com/questions/8401879/get-absolute-path-in-javascript
pathname: /questions/8401879/get-absolute-path-in-javascript
port:
protocol: http:
search:
So location.pathnameis what you want. And if you want to extract the last part use regex.
这location.pathname就是你想要的。如果您想提取最后一部分，请使用正则表达式。
var lastpart = window.location.pathname.match(/[^\/]+$/)[0];

Or if you need everything from protocol to last '/' you can use:
或者，如果您需要从协议到最后一个“/”的所有内容，您可以使用：
new RegExp('[^?]+/').exec(location.href)
and don't worry that it will match to the first '/' because '+' is a greedy quantifier, which means it will match as much as it can. First part '[^?]' is to stop matching before parameters because '/' can appear in parameter values like t.php?param1=val1/val2.
并且不要担心它会与第一个 '/' 匹配，因为 '+' 是一个贪婪的量词，这意味着它会尽可能多地匹配。第一部分 '[^?]' 是在参数之前停止匹配，因为 '/' 可以出现在像t.php?param1=val1/val2.

// "http://localhost:8080/public/help/index.html"
const loc = window.location.href;
// "http://localhost:8080/public/help/"
const path = loc.substr(0, loc.lastIndexOf('/') + 1);

Try this:
尝试这个：
var loc = window.location.href;
var fileNamePart = loc.substr(loc.lastIndexOf('/') + 1);
