Bind scroll Event To Dynamic DIV?

Question

For example, after using AJAX, I'll have a scrollable DIV. How to bind scroll events to it?

I've tried:

$(window).on("scroll", ".mydiv", function(){...})
$(document).on("scroll", ".mydiv", function(){...})
$(".mydiv").on("scroll", function(){...})
$(".mydiv").scroll(function(){...})

But they didn't work.

I am just reviving this old question because I didn't find good answer and I struggled myself for better way to listen 'scroll' event for dynamically appended element.

Since Scroll event does not bubble up in the DOM due to this we can't use on() like we use for scroll. So I came up with listening my own custom triggered event in the element where I would want to listen the 'scroll' event.

The scroll event is binded after the element is appended on the DOM followed by triggering my own custom event.

$("body").on("custom-scroll", ".myDiv", function(){
    console.log("Scrolled :P");
})

$("#btn").on("click", function(){
    $("body").append('<div class="myDiv"><br><br><p>Content1<p><br><br><p>Content2<p><br><br></div>');
    listenForScrollEvent($(".myDiv"));
});


function listenForScrollEvent(el){
    el.on("scroll", function(){
        el.trigger("custom-scroll");
    })
}

body{ font-family: tahoma; font-size: 12px; }
	
	.myDiv{
		height: 90px;
		width: 300px;
		border: 1px solid;
		background-color: lavender;
		overflow: auto;
	}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<input type="button" id="btn" value="Click"/>

I'm having the same issue and I've found the following in the jQuery .on() API:

In all browsers, the load, scroll, and error events (e.g., on an element) do not bubble. In Internet Explorer 8 and lower, the paste and reset events do not bubble. Such events are not supported for use with delegation, but they can be used when the event handler is directly attached to the element generating the event.

So unfortunately this doesn't appear to be possible.

try this modified from your code

http://jsfiddle.net/apDBE/

$(document).ready(function(){

    // Trigger
    $("#btn").click(function(){
        if ($(".myDiv").length == 0) // Append once
        $("body").append('<div class="myDiv"><br><br><p>Content1<p><br><br><p>Content2<p><br><br></div>');
    });

    // Not working
    $(".myDiv").scroll(function(){
        alert("A");
    });

    // Not working
    $(document).on("scroll", ".myDiv", function(){
        alert("A");
    });
});

Hope this help
