Gmail Function updateQuota()

[glenngould]

Hi,

I'm working on a jscript function that updates a value on my page in realtime, similar to the mail quota in gmail frontpage.

I'm a little familiar with javascript but don't know exactly how to do it. Here is the code google uses in gmail.

function updateQuota() { 
  if (!quota) {
    return;
  }
 
  var now = (new Date()).getTime(); 
  var i;
  for (i = 0; i < CP.length; i++) {
    if (now < CP[i][0]) {
      break;
    }
  }
  if (i == 0) {
    setTimeout(updateQuota, 1000); 
  } else if (i == CP.length) {
    quota.innerHTML = CP[i - 1][1];
  } else {
    var ts = CP[i - 1][0];
    var bs = CP[i - 1][1];
    quota.innerHTML = format(((now-ts) / (CP[i][0]-ts) * (CP[i][1]-bs)) + bs); 
    setTimeout(updateQuota, 1000); 
  } 
}

Basically, what I would need is a method for executing my php script that would update the value in my page. Maybe something like:

myclass.innerHTML=myfunction();

I presume it is to be fairly simple but I just don't know the jscript methods to handle these kind of events.
