Detecting when user scrolls to bottom of div with jQuery

Solution 1:

There are some properties/methods you can use:

$().scrollTop()//how much has been scrolled
$().innerHeight()// inner height of the element
DOMElement.scrollHeight//height of the content of the element

So you can take the sum of the first two properties, and when it equals to the last property, you've reached the end:

jQuery(function($) {
    $('#flux').on('scroll', function() {
        if($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight) {
            alert('end reached');
        }
    })
});

Edit: I've updated 'bind' to 'on' as per:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document.

Solution 2:

I found a solution that when you scroll your window and end of a div shown from bottom gives you an alert.

$(window).bind('scroll', function() {
    if($(window).scrollTop() >= $('.posts').offset().top + $('.posts').outerHeight() - window.innerHeight) {
        alert('end reached');
    }
});

In this example if you scroll down when div (.posts) finish its give you an alert.
