jQuery alert after 100 pixels scrolled

Question

Is it possible to fire an alert after a user scrolls 100 pixels.

Here\'s what I have so far but I know I\'m missing something;

$(window).scroll(func         


        

Answer 1

Try this:

$(document).scrollTop() >= 100) {
    // ...
}

scrollTop() returns an integer. This version will evaluate to true once you have scrolled past 100px, which might be more appropriate.
