The jQuery.when method accepts a dynamic number of arguments, however, id dose not accept an array of arguments. For example:

1
2
3
4
5
6
7
8
9
10
var d1 = new $.Deferred();
var d2 = new $.Deferred();

$.when( d1, d2 ).done(function ( v1, v2 ) {
	console.log( v1 ); // "Fish"
	console.log( v2 ); // "Pizza"
});

d1.resolve( "Fish" );
d2.resolve( "Pizza" );

What if I want to pass an array instead of requests themselves? For example, an array [d1, d2] instead of d1 and d2.

Ok, here we go, actually we can use $.when.apply:

1
2
3
4
5
6
7
8
9
10
var d1 = new $.Deferred();
var d2 = new $.Deferred();

var deferredArr = [];
deferredArr.push(d1);
deferredArr.push(d2);

$.when.apply(this, deferredArr).then(function() {
alert("All Done Loading!");
});
