create Array and jQuery Object as Key/Value for .ajax()

Hi,

I'm trying to pass in the data option for the jquery .ajax() like:
$.ajax({
  type: "POST",
  url: "some.php",
  data: {
            nametest:'jonny',
            producttest:'productval'
        }
}).done(function( msg ) {
  alert( "Data Saved: " + msg );
});

Open in new window


This page http://api.jquery.com/jQuery.ajax/ states 'data' should be:
Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key based on the value of the traditional setting (described below).

I'm trying to figure out how to create this Array or Object as Key/Value pairs in the format above.

For instance, I was trying this:
var myArray = [];
var myObj;
function testCall() {
    // we are using the array created above
    var userList = $('#userList');
    userList.children('li').each(function () {
        var userID = $(this).attr('id');
        var userName = $(this).text();
        myArray.push({
            'id':userID,
            'name':userName
        });
    });
    return myArray;
}

Open in new window


<ul id="userList">
    <li id="user1">Jim</li>
    <li id="user2">Mike</li>
    <li id="user3">Jake</li>
</ul>

Open in new window


I'm wondering also how to do this manually like:
myArray.push({
            'testid':'testval',
            'testname':'testname'
        });

in the format:
{
nametest:'jonny',
producttest:'productval'
}

and then keep adding to this array or Object as Key/Value in order for the .ajax() to work properly and pass the GET or POST vars.

check this

var array = new Array();

$("#userList li").each(function(){
    array [ $(this).attr("id") ] = $(this).html();
});

return array;
