You can use substringand lastIndexOf:
您可以使用substring和lastIndexOf：
var value = url.substring(url.lastIndexOf('/') + 1);
If the second parameter of substringis omitted, it extracts the characters to the end of the string.
如果省略子字符串的第二个参数，则将字符提取到字符串的末尾。

To get it from the URL Address:
要从 URL 地址获取它：
var value = window.location.href.substring(window.location.href.lastIndexOf('/') + 1);

Not really jQUery, but pure Javascript:
不是真正的 jQUEry，而是纯 Javascript：
var a = '/test/foo/bar';
To get the string after the last character:
获取最后一个字符后的字符串：
var result = a.substring(a.lastIndexOf("/") + 1);

Using a regex, which is just like the lastIndexOfmethod, but with the added benefit of being almost impossible to read/understand! ;)
使用正则表达式，就像lastIndexOf方法一样，但具有几乎无法阅读/理解的额外好处！;)
var lastBit = theUrl.match(/[^\/]*$/)[0];
There actually IS a benefit though, if you only wanted to get trailing numbers, or some other pattern you could adapt it:
不过，实际上有一个好处，如果您只想获得尾随数字或其他一些可以调整它的模式：
// match "/abc/123", not "/abc/foo"
var lastDigits = theUrl.match(/[0-9]*$/)[0];
// match "/abc/Pie", not "/abc/123"
var matches = theUrl.match(/\/(P[^\/]*)$/);
var lastBitWhichStartsWithTheLetterP = matches ? matches[1] : null;

As you can see from all of the answers JQuery isn't needed to do this.
正如您从所有答案中看到的那样，不需要 JQuery 来执行此操作。
You could split it:
你可以拆分它：
var url = 'www.google.com/dir1/dir2/2';
var id = parseInt(url.split('/')[url.split('/').length - 1]);

Why not use a regex?
为什么不使用正则表达式？
var p = /.+\/([^\/]+)/;
var match = p.exec(str)
alert(match[1]);
回答by kgiannakakis
var arr = window.location.split("/FormBuilder/index.php/reports/export/1");
var last_val = arr[arr.length-1];

Universal:
普遍的：
function getQueryVariable(variable)
{
var pathname = window.location.pathname.split("/");
for (i = 0; i < pathname.length; i++) {
if (pathname[i] == variable){
return pathname[i+1];
}
}
}
