Jquery: getting the variable's value from a link


I found this Thread:

But i don’t get it work :frowning:

Can someone please post the full script.

In my page I have the following code (but it does not work!?):

$(document).ready(function() {

//When you click on a link with class of poplight and the href starts with a # 
$('a.poplight[href^=#]').click(function() {
    var popID = $(this).attr('rel'); //Get Popup Name
    var popURL = $(this).attr('href'); //Get Popup href to define size

    //Pull Query & Variables from href URL
    var query= popURL.split('?');
    var dim= query[1].split('&');
    var popWidth = dim[0].split('=')[1]; //Gets the first query string value
        var path = $(this).attr("href");
        var query= path.split('?');
        var dim= query[1].split('&');
        var w= dim[0].split('=')[1];
        var h= dim[1].split('=')[1];

    //Fade in the Popup and add close button
    $('#' + popID).fadeIn().css({ 'width': Number( popWidth ) }).prepend('<a href="#" class="close"><img src="/images/close_pop.png" class="btn_close" title="Close Window" alt="Close" /></a>');

    //Define margin for center alignment (vertical   horizontal) - we add 80px to the height/width to accomodate for the padding  and border width defined in the css
    var popMargTop = ($('#' + popID).height() + 80) / 2;
    var popMargLeft = ($('#' + popID).width() + 80) / 2;

    //Apply Margin to Popup
    $('#' + popID).css({
        'margin-top' : -popMargTop,
        'margin-left' : -popMargLeft

    //Fade in Background
    $('body').append('<div id="fade"></div>'); //Add the fade layer to bottom of the body tag.
    $('#fade').css({'filter' : 'alpha(opacity=80)'}).fadeIn(); //Fade in the fade layer - .css({'filter' : 'alpha(opacity=80)'}) is used to fix the IE Bug on fading transparencies 

    return false;

//Close Popups and Fade Layer
$('a.close, #fade').live('click', function() { //When clicking on the close or fade layer...
    $('#fade , .popup_block').fadeOut(function() {
        $('#fade, a.close').remove();  //fade them both out
    return false;
