Count Down And Refresh Iframe

[jaymc]

I need some javascript that will sit on the main index page of my site and count down from 240 seconds

 

When it hits 0 it will refresh an iframe thats on the index page, then start the counter all over again

 

I have javascript that does it from within the iframe but sometimes I get page cannot be displayed and when that happens obviously it wont refresh again

 

Can anyone help?

I'm not sure I understand the problem.

I basically need javascript to sit on the index of my page.. countdown from 240 seconds and when it hits 0 it will refresh an iframe thats on the page the javascript is on

 

After that, it will simply start the countdown from 240 again and so on..

I think setInterval() is what you're after:

<script type="text/javascript">
setInterval("myRefresh()", 240000);
</script>

 

Then, your myRefresh() function would hold the code necessary to refresh the actual iframe.

Thats perfect

 

I have that working

 

Whats it like for stability though?

 

Likely to crash browsers or timeout? especially when running for 6 minutes..?

Shouldn't cause any problems... but who sits on one page for 6 minutes?

As artacus said, it really shouldn't cause a problem at all. It simply fires once every 240 seconds. It's not going to overload your script in any way.
