How to add a timer to a JSP page?

Hi,

Find the code to add timer control using Script

<SCRIPT LANGUAGE="JavaScript">

var index = 1;

var min1,sec1;

var cmin1,csec1,cmin2,csec2;

var increment = 1;

var incx;

function Minutes(data) {

for(var i=0;i<data.length;i++) if(data.substring(i,i+1)==":") break;

return(data.substring(0,i)); }

function Seconds(data) {

for(var i=0;i<data.length;i++) if(data.substring(i,i+1)==":") break;

return(data.substring(i+1,data.length)); }

function Display(min,sec) {

var disp = "";

// if(min><=9) disp=" 0";

// else disp=" ";

disp+=min+":";

if(sec<=9) disp+="0"+sec;

else disp+=sec;

return(disp); }

function Down() {

index++;

cmin2=1*Minutes(document.Online_Exam.beg2.value);

csec2=Seconds(document.Online_Exam.beg2.value);

csec2 = csec2 - increment;

csec2 = csec2 + increment;

var elem = document.getElementById("timertext");

elem.innerHTML = "

<span style=\"font-size: 10pt;\">" + Display(cmin2,csec2) + "</span>

down=setTimeout("DownRepeat(" + index + "," + increment + ")", increment * 1000);

}

function DownRepeat(ix,inc) {

if( ix == index ) {

incx = inc;

csec2 = csec2 - inc;

if(csec2 < 0) { csec2= csec2 + 60; cmin2--; }

//if( incx > 1 && cmin2 == 1 && csec2 == 0 ) incx = 1;

var elem = document.getElementById("timertext");

elem.innerHTML = "

<span style=\"font-size: 10pt;\">" + Display(cmin2,csec2) + "</span>

if((cmin2==0)&&(csec2==0))

//elem.innerHTML = "

<span style=\"font-size: 10pt; color=red\">STOP</span>

document.Online_Exam.submit();

else

down=setTimeout("DownRepeat(" + ix + "," + incx + ")", incx * 1000);

}

}

</SCRIPT>
