Async attribute in script element not working?

Question

When I load a script from an external server in the following manner

<div id="verisign-logo">
    <script type="text/javascript" src=verisign-url>
</div>

The script gets executed and a flash file is displayed in the div with Id verisign-logo. Verisign-url is a predefined variable.

Now I am trying to load and execute the script asynchronously.I added async attribute to the script tag in the following manner

<div id="verisign-logo">
    <script type="text/javascript" src=verisign-url async=true>
</div>

But the weird thing is script gets appened in the div however the flash file doesnot get displayed.What exactly is not right here?

I think your flash stuff requires script which you are loading asynchronously ..SO you cannot guarantee it will be available at the time you expect flash to work.. — Deepak Ingole

You're missing </script>. Is that a copying error or in your real code? — Barmar

@Pilot The flash image is returned by the script that I am loading. — Smrita

With reference from w3schools syntax for async loading is as follows

<script src="demo_async.js" async></script>

As far as I know that's what HTML5 compatible browsers accept what about browsers that donot support HTML 5?
