Hi is that anyone who can help me in javaScript program. i did most of the program but i need help in Palindromic Prime and also i need a help in check box and find box.
Here is the program what i have it here is mine prime.Html file..

<form name=\"numbers\">
Staring value(>1): <input type=\"text\" name=\"firstNum\" />
Ending Value(<99999: <input type=\"text\" name=\"secondNum\" />

<p>Select what you want:<br />
<input type =\"checkbox\" name=\"color\" id=\"rbutton1\"

<label for=\"rbutton1\">Prime</label>
<br />
<input type=\"checkbox\" name=\"color\" id=\"rbutton2\" value=\"find\" onclick=\"checkPalindrome();\" />
<label for=\"rbutton2\">Palindrome</label>
<br />
<input type =\"checkbox\" name=\"color\" id=\"rbutton3\"

<button onclick=\"closeWin()\">Close \"myWindow\"</button></br>

Here is p1pprime.js
function calcPrimeNumber(){
var beginNum = parseInt(document.numbers.firstNum.value);
var endNum = parseInt(document.numbers.secondNum.value);
var primeNumbs = new Array();
var ctr = beginNum;
while(ctr<=endNum)
{
if(isPrime(ctr)==true)
{
primeNumbs[primeNumbs.length] = ctr;
}
ctr = ctr+1;
}
if (primeNumbs.length == 0){
document.getElementById(\'output_content\').innerHTML = \"There were no prime no within the range.\";
}
else {
outputPrimeNums(primeNumbs);
}
}
function isPrime(num)
{
var flag = true;
for(var i=2; i<=Math.ceil(num/2); i++)
{
if((num%i)==0)
{
flag = false;
break;
}
}
return flag;
}
function outputPrimeNums(primes){
var html = \"<h2>Prime Numbers</h2>\";
for (i=0;i<primes.length;i++){
html += primes[i] + \"<td/>\";
}
document.getElementById(\'output_content\').innerHTML = html;
}
function checkPalindrome(){
var beginNum = parseInt(document.numbers.firstNum.value);
var endNum = parseInt(document.numbers.secondNum.value);
var ctr = beginNum;
while(ctr<=endNum){
num = ctr;
temp = 0;
while(num>0){
// get last digit;
temp = (temp*10)+num%10;
// reduce number by deleting last digit.
num = parseInt(num/10);
}
if(temp == ctr){
document.write(ctr +\" \");
}
else{
}
ctr = ctr+1;
}
}
