Show temporary text while php script loads

[lleroy]

I have a PHP script which takes 3-4 seconds to load and display output. The output gets displayed in a iframe with this code:

<iframe src="output1.php" name="output1" id="output1" frameborder="0" scrolling="no" marginheight="0" height="20"></iframe> <a href="output1.php?ip=10.0.0.14" target="output1">Run</a>

When I load the page, the iframe loads output1.php for the first time. I then have a button, where I can run it with a parameter. I would like it to display "loading..." in between script loads. I know there are ways to do this in javascript, but I have very little knowledge about JS, so I would prefer to do this with html or possibly php. Any easy way to do this?

A simple JS popup onload would be the easiest.. http://www.w3schools.com/jsref/event_onload.asp

yeah, but if I use onload, the loading indicater will only show at initial page load. I also have a 'refresh'-like button which runs the same script again, but when using that, the loading indicator don't show. Any other ideas?

Then I'd use php to display a non js popup
