How do you dynamically position one element on top of another?
Solution 1
This is more like a CSS question. You want to make sure the parent element (#video_div) is positioned relatively (position: relative) and the inserted element (the img) is positioned absolutely (position: absolute)
Hook it to the top left, make sure they're the same size and you're golden.
#video_div {
position: relative;
width: 300px;
height: 300px;
}
#video_div img {
position: absolute;
top: 0px;
left: 0px;
width: 300px;
height: 300px;
}
Solution 2
Assuming you mean directly on top of it (obscuring it) in the z-order, a combination of JQuery's .position() method and absolute positioning should do the trick.
$('<div>New Element</div>').css({
"position" : "absolute",
"left" : $foo.position().left,
"top" : $foo.position().top
}).appendTo($container);
Note: $container
must contain both the dynamically generated element and the target element.

I'm dynamically appending some html with jQuery and I want to insert it directly on top of another element. How do I do this?
this is the code in my application.js file:
$(document).ready(function() { $('a.oembed').embedly({maxWidth:300,'method':'replace'}).bind('embedly-oembed', function(e, oembed){ $("#video_div").append($("<img>", { src: oembed.thumbnail_url, width:200 })); }); });
The image is being inserted dynamically, and I want it to be directly on top of this:
<div id="video_div"><%= link_to 'video', @video.video_url, :class => 'oembed' %></div>
