any help? here is my code.

It'll work if you replace div with a tags. However there are a couple of other changes you ought to make, firstly make sure that the a tags aren't clickable links by returning false in the onclick event:

<a class="div123" href="#" draggable="true"
 ondragstart="handleDragStart(event)"
 ondrop="handleDrop(event)"
 ondragover="dragoveHandler(event)"
 onclick="return false;">
    HTML5 drag and drop
</a>

Secondly, IE9 doesn't accept parameters of text/plain in setData , use Text instead or add the data inside of a try...catch . Also, you should make sure the data you're adding is actually text:

e.dataTransfer.setData("Text", "" + $(e.target).index());

Finally your handleDrop function needs to preventDefault / return false because otherwise the default action for dropping a link (an a element`) is to navigate to the dropped URL:

function handleDrop(e) {
    alert($(e.target).index());
    if (e.preventDefault) {
        e.preventDefault(); // Necessary. Stops redirect.
    }
    return false;
}

Here is a jsFiddle of your code which will work in IE9 .
