Multiple container content loading with Ajax/JSON

Multiple container content loading with Ajax/JSON

I was wondering if you could be so kind to help me with a small coding problem. 

I have implemented external content loading using Ajax. And now I would like to add multiple container loading functionality using a Json object code I have.

Could you please help me incorporate the json object code into the Ajax code. My knowledge in coding is very limited :) 

Here is the detailed info:

Here is the json object:

var json = [{'id': 'content', 'wrapper': '__content-wrapper'},{'id': 'content', 'wrapper': '__content-wrapper'}] 

$.each(json, function(i, itm) {
$('#'+itm.id).wrap('<div id="' + itm.wrapper + '"></div>');
pageload(itm.id, itm.wrapper);
}

function pageload (id, wrapper) {

}


Here is the Ajax code:

$(document).ready(function() {

    var contentWrapID = '___content-wrapper';
    
    $('#content').wrap('<div id="' + contentWrapID + '"></div>');
    
    function showNewContent() {
        $("#" + contentWrapID).slideDown();
        $('#load').fadeOut();   
    }
    
    function pageload(hash) {
        if(hash) {
            $("#" + contentWrapID).load(hash + " #content",'',function(){
                if($('img:last',this).get(0)) {
                    $('img:last',this).load(function(){
                        showNewContent();
                    });
                } else {
                    showNewContent();
                }

            });
        } else {
            $("#" + contentWrapID).load("index.html #content");
        }
    }
    $.historyInit(pageload);
    
    $('#topnav li a').click(function(){
        
        var hash = $(this).attr('href');
        hash = hash.replace(/^.*#/, '');
        $("#" + contentWrapID).slideUp(300,function(){
            $.historyLoad(hash);
        });
        if(!$('#load').get(0)) {
            $('#container').append('<span id="load">LOADING...</span>');
        }
        $('#load').fadeIn('normal');
$('#topnav li a').removeClass('current'); 
$(this).addClass('current'); 
        return false;
    
    });

});

........................

As far as I understand I have  to replace this line:

var contentWrapID = '___content-wrapper';

with the json object:

var json = [{'id': 'content', 'wrapper': '__content-wrapper'},{'id': 'content2', 'wrapper': '__content-wrapper2'}]; 

But I also have to change the pageload function so that it works with the new variables that are passed:

function pageload (id, wrapper) {

} 

I'd be very grateful for any help

Best regards
