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

Take a look at the jQuery api documentation, in particular to the jQuery.ajax() function. You'll find documentation and many useful examples. This is a piece of code from that page that does exactly what you've requested:

$.ajax({
   type: "POST",
   url: "some.php",
   data: "name=John&location=Boston",
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
 });

(Of course you can also pass the data by simply using GET params and appending them to the url)
