I'm trying to get a list of JSON objects (products) from a local file using Jquery and store all the objects in a single array called allItems. The file is co-located in the same directory as the code, and it's called "allItems.json". Here's how I'm doing it now:

function getAllSupportedItems(){
    var allItems = new Array();
    $.getJSON("allItems.json",
         function(data){
             $.each(data.items, 
             function(item){
                 allItems.push(item);
             });
         });
    return allItems;
}

Based on this example: http://api.jquery.com/jQuery.getJSON/
