Question

How to Prevent an Applet from Unloading across web pages?

Answer 1

A:

Put the Applet in a frame that doesn't unload, or prevent the user from going to another page in the web page that contains the Applet.

Answer 2

A:

The only option would be to put you content in an iframe that encompasses your whole document and use absolute positionning for the applet.

<body>
 <iframe id='content' src='FIRST_URL'></iframe>
 <object id='applet'></object>
</body>

With a css like this one:

#content {
  width:100%;
  height: 100%;
}

#applet {
  position: absolute;
  left: LEFT_POSITION;
  top: TOP_POSITION;
  width: DESIRED_WIDTH;
  height: DESIRED_HEIGHT;
}

There are MANY drawbacks:

The applet will always be positionned at the same place, no matter the page
You will suffer to get the iframe full width and full height, especially in IE
It's possible you will also suffer to have the applet showing properly (an object on top of an iframe, I can't imagine what troubles you'll run into)
The applet will stay if your user click to a link leading outside of your site unless you set a target for the link (ie, target='top' or target='__blank')

If I did this, the browser URL would never change from page to page. Not really what I'm looking for.

Answer 3

A:

I thought maybe there'd be a way to popup a tiny browser window and have the applet load in that, then using Javascript somehow pull in the applet from the smaller window into the larger browser.

I don't think I can manipulate the DOM in this way though.

Any other ideas?

Answer 4

A:

You could show a warning, this way:

if(window.body)window.body.onbeforeunload=function(){if(window.event)window.event.returnValue="UNLOAD MSG";};else window.onbeforeunload=function(){return "UNLOAD MSG";};

This works in allmost every browser, but you cannot change the text surrounding your text.
