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

You can't.
$.each can only iterate over arrays or objects. You're looking for the for loop:

for(var n = 0; n < 5; n++) {
    alert(n);
}
