<script language="JavaScript">
answer = 7 % 2;
// odd numbers will always a modulas (answer = 5)
answer = 6 % 2
// even numbers will return 0 in answer (answer = 0)
</script>

var sum = 0;
document.write('The odd number are: ');
while ( number > 0){
if (number%2 == 1) {
document.write(number + ' ')
sum = sum + number;
number-- ;

I tried out the program you wrote yourself, and it returns the uneven numbers, what is there to solve?
If you would like the program to be re-useable without refreshing, calculates the even and uneven numbers and their sums you could try the following:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Even, uneven and sum of those numbers</title>
</head>
<body>
<script type="text/javascript">
function Numb() {
// Resetting numbers
document.getElementById("even").innerHTML = "";
document.getElementById("uneven").innerHTML = "";
// Retrieving the number
var number = parseInt(document.getElementById("number").value);
// Setting the sums of the even and uneven numbers 0
var unevensum = 0;
var evensum = 0;
// Loop lasts untill the number has reached 0
while ( number > 0){
// If the number is uneven:
if (number%2 == 1) {
// Updating the uneven number list
document.getElementById("uneven").innerHTML += number + ' ';
// Updating the unevensum with the number
unevensum = unevensum + number;
// Decreasing the number
number-- ;
// If the number is even
} else {
// Updating the even numbers list
document.getElementById("even").innerHTML += number + ' ';
// Updating the evensum with the number
evensum = evensum + number;
// Decreasing the number
number-- ;
}
}
// Updating the evensum and unevensum in the document (so their values are visible)
document.getElementById("evensum").innerHTML = evensum;
document.getElementById("unevensum").innerHTML = unevensum;
}
</script>
<form action="#" method="post">
<h3>Even, uneven and sum of those numbers</h3>
Please enter a number here: <input type="text" maxlength="5" id="number" size="4" />
<input type="button" value="Calculate the numbers!" onclick="Numb()" /><br /><br />
<span style="text-decoration:underline; font-weight:bold;">Results:</span><br /><br />
<span style="font-weight:bold;">Even numbers:</span> <span id="even"></span><br /><br />
<span style="font-weight:bold;">Sum of even numbers:</span> <span id="evensum"></span><br /><br />
<span style="font-weight:bold;">Uneven numbers:</span> <span id="uneven"></span><br /><br />
<span style="font-weight:bold;">Sum of uneven numbers:</span> <span id="unevensum"></span><br /><br />
<br />
</form>

I tried it to0 and it works. I did change this line though, because modulas won't always return 1.
if (number%2 == 1) {
changed to
if (number%2 != 0) {
