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?
当前回答
var pathname = window.location.pathname; // Returns path only
var url = window.location.href; // Returns full URL

这就是塞巴斯蒂安·巴斯的答案。
如果href是你正在解析的变量，new URL会抛出TypeError，所以为了安全起见，你应该尝试- catch
try{
const segments = new URL(href).pathname.split('/');
const last = segments.pop() || segments.pop(); // Handle potential trailing slash
console.log(last);
}catch (error){
//Uups, href wasn't a valid URL (empty string or malformed URL)
console.log('TypeError ->',error);
}
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。
或者你可以使用正则表达式:
alert(href.replace(/.*\//, ''));
var pathname = window.location.pathname; // Returns path only
var url = window.location.href; // Returns full URL

你可以先删除末尾的/，然后获取url的最后一部分
let locationLastPart = window.location.pathname
if (locationLastPart.substring(locationLastPart.length-1) == "/") {
locationLastPart = locationLastPart.substring(0, locationLastPart.length-1);
}
locationLastPart = locationLastPart.substr(locationLastPart.lastIndexOf('/') + 1);
