Auto refresh

**chefo** · 06-29-2011

Hi all
i have a fedora 15 LXDE

I have a web based ticketing system that i need to have it refresh every X minutes.
however the refresh button reloads the page but does not grap new contents. there is a button to refresh each pain of the page that grabs the new info.
Apperantly i need some kind of script in order to have that button(link) refresh every so often.
Im stuck as im not a scriptor nor linux guru

Can you help me out here?

Thanks

Sounds like you need a bit of javascript. What I would do is:

1. throw together a javascript function that invokes that button

2. have that function called whenever the page loads (via the javascript body onload event)

3. use meta refresh element to have the page auto-refresh every 5 seconds (or whatever number you want) - note: using meta refresh is legacy, but hey it works for me

E.g.:

Code:

<html>
<head>
<meta http-equiv="REFRESH" content="5">
<script type='text/javascript'>
  function invoke_reload_button() {
    // do stuff to invoke that button
  }
</script>
</head>
<body onload="invoke_reload_button()">
html code blah blah
cool button, etc.
</body>
</html>

This portion of the code I posted does that:

Code:

<body onload="invoke_reload_button()">

The onload portion is a Javascript event. See here for more info.

It says that every time the page is loaded (either via the browser refresh button, or any HTML that causes the page to reload) call the invoke_reload_button javascription function - which of course must be defined by you.
