Question

i have this chatbox, and when users login i want it to send a message like this:

Admin: User is online

I really want to use a javascript code for this, because i can work with it quite good. I already have some example, but the problem here is that it does not do something until it is called to do it's function. THATS what i want to achieve, just that when the page is opened up, it does that function one time.

function onLine(message)
{
document.writeform.bericht.value+=message;
document.writeform.bericht.focus();
write1();
}

explanation: onLine is the function and (message) tells what it should say. For example: 

...
onclick="onLine('User is online');"
...

the function write1() sends it.

HELP?!

Was it helpful?

Solution

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.
