Nameless,
I see someone mentioned the setTimeout(function, milliseconds) function for
JavaScript. I would also like to point out that you can use
setInterval(function, milliseconds) in order to have an event repeat at a set
interval. For instance, let's say you had a page laid out like so:
---
<div id="blah">
Text here
</div>
---
You would want to add a script somewhere that would begin the interval in order
to update the div:
---
<script type="text/javascript">
function ajaxRequest()
{
// <insert postback code here>
document.getElementById("blah").innerHTML = ajax.responseText;
}
var t = setInterval("ajaxRequest()", 5000);
</script>
---
This assumes that your XmlHttpRequest object is named "ajax". Assigning the
interval to variable "t" ensures that you can clear the interval if you need to
(via "clearInterval(t);").
I suppose "innerText" can be used instead of "innerHTML", as well. I would
recommend using innerHTML only if you will be populating the div with HTML
code, however.
Hope this helps,
