Answer 1

var my_arr = new Array(listingID, site_click, browser, dimension);
    var AjaxURL = 'http://example.com';
    var jsonString = JSON.stringify(my_arr);
    $.ajax({
        type: "POST",
        url: AjaxURL,
        data: {data: jsonString},
        success: function(result) {
            window.console.log('Successful');
        }
    });

This has been working for me for quite some time.

Answer 2

  var value1=$("id1").val();
  var value2=$("id2").val();
    data:"{'data1':'"+value1+"','data2':'"+value2+"'}"

You can use this way to pass data

Answer 3

I would recommend using a hash instead of a param string:

data = {id: id, name: name}
