我如何得到一个url的最后一段?我有下面的脚本，显示点击锚标记的完整url:
$(".tag_name_goes_here").live('click', function(event)
{
event.preventDefault();
alert($(this).attr("href"));
});
如果url为
http://mywebsite/folder/file
我如何才能让它在警告框中显示url的“文件”部分?

一种避免查询参数的方法
const urlString = "https://stackoverflow.com/last-segment?param=123" const url =新的url (urlString); url。搜索= "; const lastSegment = url.pathname.split('/').pop(); console.log (lastSegment)

Javascript有与字符串对象相关联的函数split，可以帮助你:
const url = "http://mywebsite/folder/file";
const array = url.split('/');
const lastsegment = array[array.length-1];
更新raddevus答案:
var loc = window.location.href;
loc = loc.lastIndexOf('/') == loc.length - 1 ? loc.substr(0, loc.length - 1) : loc.substr(0, loc.length + 1);
var targetValue = loc.substr(loc.lastIndexOf('/') + 1);
打印url的最后一个路径为字符串:
test.com/path-name = path-name
test.com/path-name/ = path-name
// Store original location in loc like: http://test.com/one/ (ending slash)
var loc = location.href;
// If the last char is a slash trim it, otherwise return the original loc
loc = loc.lastIndexOf('/') == (loc.length -1) ? loc.substring(0,loc.length-1) : loc.substring(0,loc.lastIndexOf('/'));
var targetValue = loc.substring(loc.lastIndexOf('/') + 1);
targetValue = 1
如果你的url看起来像:
http://test.com/one/
or
http://test.com/one
or
http://test.com/one/index.htm
然后loc最终看起来像: http://test.com/one
现在，因为您需要最后一项，所以运行下一步来加载最初需要的值(targetValue)。
var targetValue = loc.substr(loc.lastIndexOf('/') + 1);
// Store original location in loc like: http://test.com/one/ (ending slash) let loc = "http://test.com/one/index.htm"; console.log("starting loc value = " + loc); // If the last char is a slash trim it, otherwise return the original loc loc = loc.lastIndexOf('/') == (loc.length -1) ? loc.substring(0,loc.length-1) : loc.substring(0,loc.lastIndexOf('/')); let targetValue = loc.substring(loc.lastIndexOf('/') + 1); console.log("targetValue = " + targetValue); console.log("loc = " + loc);

最短的方法如何获得URL最后一段与split()， filter()和pop()
函数getLastUrlSegment(url) { 返回新的URL(URL).pathname.split('/').filter(Boolean).pop(); ｝ console.log (getLastUrlSegment (window.location.href)); console.log (getLastUrlSegment (' https://x.com/boo ')); console.log (getLastUrlSegment (' https://x.com/boo/ ')); console.log (getLastUrlSegment (' https://x.com/boo?q=foo&s=bar=aaa ')); console.log (getLastUrlSegment (https://x.com/boo?q=foo这')); console.log(getLastUrlSegment('https://x.com/last带空格的段'));
对我有用。
