Get a substringafter the last index of/.
var url = 'http://www.site.com/234234234';
var id = url.substring(url.lastIndexOf('/') + 1);
alert(id); // 234234234
It's just basic JavaScript, no jQuery involved.
它只是基本的 JavaScript，不涉及 jQuery。

var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1]; // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment

Snippet for getting the parameters from URL. Use javascript to get the URL parameters either from current window location or static URL into the argument for the function call.
用于从 URL 获取参数的代码段。使用 javascript 将 URL 参数从当前窗口位置或静态 URL 获取到函数调用的参数中。
javascript
javascript
function getUrlParameters(parameter, staticURL, decode){
var currLocation = (staticURL.length)? staticURL : window.location.search,
parArr = currLocation.split("?")[1].split("&"),
returnBool = true;
for(var i = 0; i < parArr.length; i++){
parr = parArr[i].split("=");
if(parr[0] == parameter){
return (decode) ? decodeURIComponent(parr[1]) : parr[1];
returnBool = true;
}else{
returnBool = false;
}
}
if(!returnBool) return false;
}
To get the parameter “id” from above static URL, use the following:

var idParameter = getUrlParameters("id", "http://www.example.com?id=1234&auth=true", true);

console.log(v)
You will get only "/";
你只会得到“/”；

You could just use window.location.hashto grab the id.
你可以window.location.hash用来获取id。
var id = window.location.hash;
I don't think you will need that much code to achieve this.
我认为您不需要那么多代码来实现这一点。

Just because I can:
只因为我可以：
function pathName(url, a) {
return (a = document.createElement('a'), a.href = url, a.pathname); //optionally, remove leading '/'
}
pathName("http://www.site.com/234234234") -> "/234234234"

Using the jQuery URL Parser plugin, you should be able to do this:
使用jQuery URL Parser 插件，您应该能够做到这一点：
jQuery.url.segment(1)
