Java Script to drag and drop image in HTML5

Hi guys, some days ago i came across a situation where i have to drag and drop a image into a rectangle in a web page. I tried following and it works using HTML5.

<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
#div1 {width:150px;height:70px;padding:10px;border:1px solid #aaaaff;}
</style>


<script type="text/javascript">

function allowDrop(ev)
{
ev.preventDefault();
}

function drag(ev)
{
ev.dataTransfer.setData("Text",ev.target.id);
}

function drop(ev)
{
ev.preventDefault();
var data=ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(data));
}

</script>

</head>
<body>

<p>Drag the image into the rectangle:</p>

<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<br />
<img id="drag1" src="img_logo.gif" draggable="true" ondragstart="drag(event)" width="336" height="69" />

</body>
</html>
