The following piece of code alerts the mouse position in IE , but in Firefox and other browsers, it alerts "undefined". 

<body onbeforeunload="test(event);">

function test(e){
     if (!e) var e = window.event;
     alert(e.clientX);
}

The above code is to get the mouse position when the browser window is closed.Please advise how I need to amend the above code to return the mouse position in all browsers

My requirement is to open a new window only when a browser is closed and NOT on page refresh. Is there any other way by which the browser close can be detected in all browsers?

just add mousemove handler that will store mouse position in variable, like this:

<body onbeforeunload="test(event);" onmousemove="storeMouse(event);">

var mouse;
function storeMouse(e)
{
    if(!e) e = window.event;
    mouse = {clientX: e.clientX, clientX:e.clientY};
}


function test(e){
     alert(mouse.clientX);
}

  • Thanks Alex,the above code returns the mouse cordinates.But i cant generalise a rule for this.One time when I close the browser,clientX & clientY alerts(0,345).The next time it alerts (372,45).The coorinates next to the close(X)button of the browser is required to generalise something like the below code to work in FF : if((window.event.clientX <0 || window.event.clientY <0) {window.open("...")} Since I am getting extremely different ranges of coordinates each time the mouse points to close button, I cannot write a condition similar to the above. Please can you shed some light on this? – Eifel Aug 30 '10 at 11:47
