    how a game timer is designed for many levels with different times i.e., for Level1 10 sec, Level 2 20 sec, etc. i got a code but its not working for Levels individually as its overlapping and not working. 

    <script>
   
    var CCOUNT = 8;
   
    var t, count;
   
    function cddisplay() {
        // displays time in span
        document.getElementById('timespan').innerHTML = "Time Left:" + count;
    };
   
    function countdown() {
        // starts countdown
        cddisplay();
        if (count == 0) {
          alert('time is up');
                    location.reload();                     
        } else {
            count--;
            t = setTimeout("countdown()", 1000);
        }
    };
   
    function cdpause() {
        // pauses countdown
        clearTimeout(t);
    };
   
    function cdreset() {
        // resets countdown
        cdpause();
        count = CCOUNT;
        cddisplay();
    };
   
</script>
 
<body onload="cdreset()">
<span id="timespan"></span>
<input type="button" value="Start" onclick="countdown()">
<input type="button" value="Stop" onclick="cdpause()">
<input type="button" value="Reset" onclick="cdreset()">
</body>

    Create a variable which holds count-down time with global scope in your JS , and change value of that depending on your level , and call functions as usual which use this variable to countdown from.
    In your code , I see nothing about levels and their countdown values. Your code just reloads the page and ofcourse the whole process repeats. You must either not-reload and use the global variable method I suggested above or reload with a change in the script. The change could be a javascript code change to load a new level page which has a higher countdown value , or change the same page's JS dynamically with PHP like index.php?level=2 gives new JS with higher countdown.

    Also , take a look at : http://papermashup.com/read-url-get-variables-withjavascript/
    You might be able to do this with JS alone using the above hint.
