How to check activity on your page.

Event Handling

How to check activity on your page.

by  Targol  Posted    (Edited  )
Here is a little script I did to detect if users ar sleeping on a page ;-). May be it can help some.
Code: 
<html>
<head>
<script language="javascript">

  var oInterval;
  var MAX_WITHOUT_ACTIVITY=10000; //number of milliseconds without activity before reload.
  
  function InitPage() {
    var oHid_h = document.getElementById("hid_lastActivity_h");
    var oHid_mn = document.getElementById("hid_lastActivity_mn");
    var oHid_s = document.getElementById("hid_lastActivity_s");
    var oDate=new Date();
    oHid_h.value = oDate.getHours();
    oHid_mn.value = oDate.getMinutes();
    oHid_s.value = oDate.getSeconds();
    oInterval = window.setInterval("VerifyActivity()", 10000); // check every 10 seconds    
  }

  function Activity() {
    var oHid_h = document.getElementById("hid_lastActivity_h");
    var oHid_mn = document.getElementById("hid_lastActivity_mn");
    var oHid_s = document.getElementById("hid_lastActivity_s");
    var oDate=new Date();
    oHid_h.value = oDate.getHours();
    oHid_mn.value = oDate.getMinutes();
    oHid_s.value = oDate.getSeconds();
  }
  
  function VerifyActivity() {
    var oHid_h = document.getElementById("hid_lastActivity_h");
    var oHid_mn = document.getElementById("hid_lastActivity_mn");
    var oHid_s = document.getElementById("hid_lastActivity_s");
    var oDate=new Date(); // current date and time
    var oLastActDate=new Date(oDate.getYear(), oDate.getMonth(), oDate.getDate(), oHid_h.value, oHid_mn.value, oHid_s.value); // last activity date and time.
    if ((oDate.valueOf() - oLastActDate.valueOf()) > MAX_WITHOUT_ACTIVITY) 
       Alert("Are you sleeping ? You didn't do anything during the past " + (MAX_WITHOUT_ACTIVITY /1000) + " seconds.");
  }
  
</script>
    </head>
    <body onload="InitPage();" onmousemove="Activity();" onkeydown="Activity();">
        <input id="hid_lastActivity_h" type="hidden" value=""/>
        <input id="hid_lastActivity_mn" type="hidden" value=""/>
        <input id="hid_lastActivity_s" type="hidden" value=""/>
    </body>
</html>

- Change the value of "MAX_WITHOUT_ACTIVITY" to change the time before "alert" or anything you want to do.
- I didn't take in account the day so this script won't work if user logs at 23:59:59. (11:59:59PM).
