Getting a Parameter on The URL

Question

It's common to use URL parameters to show dynamic information, just like here on StackOverflow:

http://stackoverflow.com/questions/1183842

But would that be possible when you're without any language like PHP or others? Is there any way to get that value using JavaScript and capture it inside a variable to present it like this:

<h1>param_variable</h1>

Look at [this](http://stackoverflow.com/questions/4467664/get-url-parameters-from-current-url-using-prototype-javascript/4467681#4467681) anser. — István Ujj-Mészáros, Dec 18 '10 at 17:55
That's the type of parameter I need: `/1183842`, that looks like a folder and not like a parameter — Nathan Campos, Dec 18 '10 at 17:55

window.location.href contains the current URL. With some string manipulations you can grab anything you want from it.

In this case:

var url = window.location.href;
var id = url.split('/')[4];
alert(id);

Will alert

In JavaScript you can get the current page's url like this:

   var url = location.href;

You may then need to parse it your self to find the parameter that you are looking for.
