Trying to send an array from jquery to PHP function

Question

I'm trying to load an array in my javascript. I need to send this array in some format to a PHP script that I'm going to call. In the example below, gSelectedMeds is my array. The value count will tell the PHP script how many meds items to expect to receive. I'm having trouble getting the data from the array into a format that I can send via the data option of $.ajax. Any help would be greatly appreciated!!

The part of the code below that is giving me grief at the moment is the data option:

$('#export').click(function() {
    $.ajax({
        url:'ajax-exportMeds.php',
        data: 
            {"number":gSelectedMeds.length},
            $.each(gSelectedMeds,
                function(intIndex, objValue){
                    {"med"+intIndex:objValue},
                }
            ),
        type: "GET",
        //dataType: "text",
        success: function(data){
            $('p#allMeds').text('');
            $('a.bank').text('');
            //clear array, bank and storedList divs
            $(this).text('');
            gSelectedMeds[] = '';
            //$('ul#storedList').fadeOut('fast');
            $('ul#storedList').text('');
            return false;
        },
    }),
});

You should send the data as json. Then you can read it using json_decode() in php >= 5.2.0

do I need to create the JSON up front? how would I send it using the data option?

actually, I just used 'JSON.stringify' and that seems to have worked so far

I ended up stringing out the array and sending a count at the end of the url that I called:

$('#export').click(function() {
        $.each(gSelectedMeds, 
         function(intIndex, objValue) {
            i=intIndex + 1;
            if(i>1) {string+='&';}
            string+='med'+i+'="'+objValue+'"';
         }
       )

       string += "&count="+i;

        $.ajax({
            url: 'ajax-exportMeds.php?'+string,
            type: "GET",
            dataType: "text",
            success: function(data){
                  $('#dialog_layer').dialog({
                        autoOpen: true,                                                 
                        bgiframe: true,
                        modal: true,
                        closeOnEscape: true,
                        buttons: {
                            "OK": function() { $(this).dialog("close"); }
                        }      
                  })
             }
        })
    });
