Extract URL fragment using jquery

var url = window.location.pathname;
var id = url.substring(url.lastIndexOf('/') + 1);

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

var url = "http://www.site.com/234234234"
var stuff = url.split('/');
var id = stuff[stuff.length-1];
//id = 234234234

const url = "http://www.example.com/1234"
const id = url.split('/').pop();

Try this, it is much easier

The output gives 1234

You could just use window.location.hash to grab the id.

var id = window.location.hash;

I don't think you will need that much code to achieve this.

try this javascript

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.

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);

or

var idParameter = getUrlParameters("id", "", true);

My url is like this http://www.default-search.net/?sid=503 . I want to get 503 . I wrote the following code .

var baseUrl = (window.location).href; // You can also use document.URL
var koopId = baseUrl.substring(baseUrl.lastIndexOf('=') + 1);
alert(koopId)//503

If you use

var v = window.location.pathname;
console.log(v)

You will get only "/";

Using the jQuery URL Parser plugin, you should be able to do this:

jQuery.url.segment(1)

Just because I can:

function pathName(url, a) {
   return (a = document.createElement('a'), a.href = url, a.pathname); //optionally, remove leading '/'
}

pathName("http://www.site.com/234234234") -> "/234234234"

Yet another option using the built-in URL interface which worth it when one has more URL specific work to do besides string extraction.

The URL interface is used to parse, construct, normalize, and encode URLs. It works by providing properties which allow you to easily read and modify the components of a URL.

const url = new URL('http://www.foo.bar/234234234');
alert(url.pathname.slice(1)); // 234234234

Try this

var url = "http://www.exmple.com/234234234"
var res = url.split("/").pop();
alert(res);

this would cover all possible cases.

window.location.href.split("/").pop().split("?")[0];

Though the solution @BalusC provided will work for the question's context. But if the url contains some query params like the one below it will not work.

http://www.example.com/234234234?limit=10&sort=desc

In this scenario you can use the following:

const url = "http://www.example.com/234234234?limit=10&sort=desc"

const id = url.substring(url.lastIndexOf('/') + 1, url.indexOf("?"));

Now id will contain only the id number 234234234.

Hope this helps.

You can easily use this JQuery code:

<script>
$(function () {
    var getURL = new URL(window.location.href);
    var Id = getURL.pathname.split('/').pop();
});
</script>
