Anti-reloading JS files

1. A small data is associated now to a DOM element via jquery api:

<script>
$.data(document.body,
 "test","I'm the Body!");
</script>

Show $.data(document.body, "test")

2. Let's invoke a modal dialog several times, displaying remote content. The point: jQuery will process html content, containing script tags with src.

Open a jQuery UI dialog

Check in Firebug what js files are downloaded and executed while the action is being processed.

Be warned: Firebug, if opened, may freeze the page for some seconds here.

3. Check what is in jQuery's storage now.

You should see an alert with text "I'm the Body!".

Show $.data(document.body, "test")

NLSClientScript prevented to pull the same libraries more than once, this way it prevents unwanted re-initializations.

Now repeat the flow without NLSClientScript.
