Live variable?

[Atomiku]

Well, Before I ask the question I would just like to say thanks for all the previous help you guys/gals have given me 🙂

Anyway, How would I somehow use Javascript/Php to get a string from a file, then every second put what is on that file onto the page without actualy refreshing the page?

For example, If you goto www.gmail.com it says: "2222.2309823 mb of space used so far!" and it updates live without refreshing the page... So umm... How do I do that 😛

Thanks in advance, Matt.

Edit: Apon further inspection of gmails live update script, I found out that it just increased the string every second by doing something like this: time() * 54 / 51

Anyway, Its still possible tho isnt it?

Well just look at the source. It seems to be just a javascript application.

function el(id) {
  if (document.getElementById) {
    return document.getElementById(id);
  } else if (window[id]) {
    return window[id];
  }
  return null;
}

var CP = [
 [ 1114930800000, 2150 ],
 [ 1117609200000, 2250 ]
];

var quota;

var ONE_PX = "https://gmail.google.com/gmail/images/c.gif?t=" +
             (new Date()).getTime();

function LogRoundtripTime() {
  var img = new Image();
  var start = (new Date()).getTime();
  img.onload = GetRoundtripTimeFunction(start);
  img.src = ONE_PX;
}

function GetRoundtripTimeFunction(start) {
  return function() {
    var end = (new Date()).getTime();
    SetGmailCookie("GMAIL_RTT", (end - start));
  }
}

function OnLoad() {
  el("gaia_loginform").onsubmit = lg;
  gaia_setFocus();
  LogRoundtripTime();
  if (!fixed) {
    FixForm();
  }
  if (!quota) {
    quota = el("quota");
    updateQuota();
  }
}

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 = 'Over ' + 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); 
  } 
} 

var PAD = '.000000'; 

function format(num) { 
  var str = String(num); 
  var dot = str.indexOf('.'); 
  if (dot < 0) { 
     return str + PAD; 
  } if (PAD.length > (str.length - dot)) { 
    return str + PAD.substring(str.length - dot); 
  } else { 
    return str.substring(0, dot + PAD.length); 
  } 
}

</script>

That is a portion of the source- next they call it.

<script>
<!--
quota = el("quota");
updateQuota();
// -->
</script>

Hope this may have helped.
