How to pass value from javascript to php file

Question

I am getting value via JQuery as something like this

var query= popURL.split(\'?\');  
var dim= query[1].split(\'&\'); 
var popWidth = dim[0].sp

well, if you only want to send that data to the server and you don't want to retrieve anything else and don't know or don't want to use ajax, a more simpler solution would be to attach the desired url on a hidden dom object. such as :

witch can be added to the dom in multiple ways.

If you want to use ajax, I recommend using a library such as jQuery, wich is optimized for cross-browser web apps. With jQuery, the syntax is very simple :

$.get(
    "http://my-host.com/my-script.php",
    {"id" : id},
    function(data){
        // do something with the response
    }
);

You could use "post" instead of "get" depending on your needs. I recommend you take a peak at jQuery documentation.
