Detect the scrolling to bottom of the page using jQuery.

jquery-scroll-bottom.js

$(window).on("scroll", function() {
	var scrollHeight = $(document).height();
	var scrollPosition = $(window).height() + $(window).scrollTop();
	if ((scrollHeight - scrollPosition) / scrollHeight === 0) {
	    // when scroll to bottom of the page
	}
});

@areghunanyan thanks

$(window).scroll(function() {  
    var scrollHeight = window.scrollY || $(window).scrollTop();                                          
        if ((window.innerHeight + scrollHeight) >= document.body.offsetHeight) {                       
            // do something                                                    
        }                                                                                                                
}); 

I fixed little bit to work on ie too. this works fine for me.

If you want to do it in a element scroll, you can do this:

// ...
        var parent = $('#parent')
        var child = $('#child')
parent.on("scroll", function() {
	if (parent.scrollTop()+parent[0].offsetHeight-child[0].scrollHeight === 0) {
	    // when scroll to bottom of the page
	}
});

Awesome, thanks. This should be the first result for anyone who is searching for 'detect scroll to botton of page using jquery'.
