    <SCRIPT LANGUAGE="JavaScript">
    <!--
    var time = 60;
    function foo()
    {
    time -= 1;
    if (time == 0)
    {
    document.getElementById("tt").value = "OVER";
    alert("close");
    window.close();
    }
    else
    {
    document.getElementById("tt").value = "Time left: " + time;
    setTimeout(foo, 1000);
    }
    }
    foo();
    //-->
    </SCRIPT>like this.
