jQuery $.when() with variable arguments

Question

I want to send [1, n) AJAX-requests to the server and after all have returned a result a modal dialog should be closed. $.when(a(), b(), c()) would be perfect, but I don't know how to pass the variable count of functions to $.when as parameter. Any ideas how to solve this problem?

Call the functions and add their return values to an array. Then call $.when passing the array as argument like so:

$.when.apply($, array)

See Function.prototype.apply ^[MDN] for more information and my answer here for an extended example.

Sometimes it's just time to knock one's head against the table... JS is too beautiful to get all of it's beauty – .apply() is one of it! Thanks a lot for the "Denkanstoß" ;-)
