.When() and .done() using an array with .done

Question

I am writing a google content script and my program needs to make roughly 30 AJAX calls to the server. I am using JQuery\'s .when function in conjunction with .apply to pas

Answer 1

If you look at the examples for $.when, you see that the call back gets passed an argument for each promise. If that promise came from an Ajax call, then each argument is an array of the form [ data, statusText, jqXHR ].

So you you just have iterate over the arguments and extract the first element. $.map makes that very easy:

$.when.apply($, requests)
  .then(function() {
    return $.map(arguments, function(v) {
      return v[0];
    });
  })
  .done(callback);
