Answer 1

A:

It sounds like what you're really asking is "how can I cause a particular javascript function to be called when a page loads".

If that's correct:

If you're using jQuery, which I recommend, then you can just do

$(document).ready( function() {
    onLine("User is online");
});

Without jQuery, you can assign a method to the body's onLoad event:

But the body.onload approach can come into conflict with other actions that may be assigned to that event; the jquery approach is safer.

Sure, or in a script tag anywhere on the page.

Answer 2

+1 A:

Do you want to run that function once when the page is loaded? If so, you have many possible ways to do it. A couple of simple ones:

<body onload="onLine('User is online')">

This will call the function when all the page components are loaded. You could also add this to the end of the page:

<script type="text/javascript">
  onLine('User is online');
</script>

There are also javascript libraries like jQuery and prototype, which you should have a look at if you haven't yet.
