hi all

like there is a url

Code:

manage_products.php?page=2

If i want to fetch page id in php then i will write

Code:

$page=$_REQUEST['page'];

Now if i want to fetch page id in Javascript then what should be my code in javascript.

Code:

var url = window.href.toString();
var id  = url.match(/\?page=(\d+)/);

if (id[1])
{
    alert('The ID is: ' + id[1]);
}
else
{
    alert('No ID found');
}

... untested, but should work.

Should be:

HTML Code:

var url = window.location.href.toString();

or

var url = location.href.toString();

or

var url = window.location.href;

or

var url = location.href;

hi nico

thanks. it works fine but as sugested by job0107 with window.location.href.toString();

now if i need to fetch value that is not numeric,
like if i have url like

Code:

manage_products.php?choice=free

if i need to fetch value of choice that is "free" and its not numeric, then will this same function work or i need a different function for that.
