jQuery .then() call two functions

Question

If I have three functions a, b, and c :

function a() {
    var deferred = new $.Deferred();
    // stuff -- resolve deferred once async method is complete
    return deferred.promise();
}

a().then(b)

This works fine, but how could I also call function c after a is finished?

Something like:

a().then(b,c)

Answer 1

大多数情况下，您可以使用done（） ：

a().done(b, c);

Answer 2

You can call the both function at the same time using a s callback function.

a().then(function () {
    b();
    c();
});

Answer 3

You can chain them

a().then(b).then(c)
