how to make jquery each a number

Question

This is my code:

$.each(3, function(n) {
    alert(n);
});

I want to alert three times but it doesn\'t work. What can I do?

Answer 1

each must operate on an object. Try to create an array of length 3, e.g.

$.each(new Array(3),
       function(n){alert(n);}
);

Of course, I don't see the reason to avoid normal Javascript.

for (var n = 0; n < 3; ++ n)
   alert(n);
