Dynamic multiple Deferred jQuery Ajax calls

Question

Using the Deferred pattern from jQuery http://api.jquery.com/jQuery.when/, I am trying to make multiple jsonp ajax calls and wait for the results before moving to the next step.

You can use arguments, which is a special king of object holding all arguments passed to a function

$.when.apply($, requests).done(function () {
    console.log(arguments); //it is an array like object which can be looped
    var total = 0;
    $.each(arguments, function (i, data) {
        console.log(data); //data is the value returned by each of the ajax requests

        total += data[0]; //if the result of the ajax request is a int value then
    });

    console.log(total)
});
