Storing php $_GET variable in a javascript variable?

How can I mimic $_GET in JavaScript, and display the value of the $_GET, so: how can I do this kind of thing in JavaScript:

if($_GET['id'] == 1)
{
    //Do something
}

Answer 1

Could always use document.location.href to do this.

Something like:

var url = document.location.href, get;
get = url.split('?');
get = get.split('&');

Which will leave you with an array of the $_GET variables. Hope that helps.

Answer 2

There are two ways to achieve what you want:

1. Parse the query string, as mentioned by knittl
2. Store the $_GET contents in the user's session on the server side, and use an AJAX request to retrieve the data from the session.

Answer 3

You need to get the URL parameters I'd suggest using a regular expression and/or jQuery, a quick example:

$.getUrlParameters = function(name, url) {
    var theURL = url || window.location.href;
    var results = new RegExp('[\\?&]' + name + '=([^&#]*)').exec(theURL);
    if (!results) { return 0; }
    return results[1] || 0;
}
