Hi,
To find whether the user has closed the window without clicking logout, i included the following lines in my script. This would track the window close regardless of its status(Window close in maximised state or window close in minimised state)

<script language="JavaS cript">
function initUnload()
{
var top=self.screen Top;
if (top>9000)
alert("window closed"+top);
else if(top<0)
alert("window closed"+top);
}
window.onunload = initUnload;
</script>

Thanks,

On a project I'm currently working on, I needed to record a users last access time when they left the website, either by logging out, closing the browser, or visiting another website. You want to use the onbeforeunload event. I had this run a javascript function to make a synchronous (ajax) call to a PHP script which did the work. Using the onbeforeunload event will do what you want.

My code, if it helps:

    // add event listener
    function addListener(obj, event, func) {
      var obj = (typeof obj == 'string' ? d.getElementById(obj) : obj);
      if (obj && obj.addEventListener) {
        obj.addEventListener(event, func, false);
      } else if (obj && obj.attachEvent) {
        obj.attachEvent('on'+event, func);
      }
    }
    
    // return AJAX object
    function getHttpXml() {
      if (window.XMLHttpRequest) {
        return new XMLHttpRequest();
      } else if (window.ActiveXObject) {
        try {
          return new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
          try {
            return new ActiveXObject("Microsoft.XMLHTTP");
          } catch (e2) { } // no Ajax support
        }
      } return null;
    }
    
    addListener(window, 'beforeunload', bye);
    var xmlHttp = getHttpXml();
    
    function bye() {
      if (xmlHttp) {
        var url = "script.php?action=leaving";
        xmlHttp.open("GET", url, true);
        xmlHttp.send(null);
      }
    }

You can add this in the head of your html page, if you want, just edit the relevant line to change the filename / parameters you want to call. I hope that helps.
