Need Help with Color changer!

Recommended Posts

I made a useful page that can count specific letters in a phrase. I want to display the answer in different colors depending on the last digit of the time, for example if it's 2:19,2:29,or 2:39 it'll display the same color (9). So i want different colors for 0-9. I have no idea how i would apply this to what i have any help would be appreciated!!!

Here's what I have:

<html>
<head>

<script lanuage="javascript" type="text/javascript">
<!--
function countLetters(fN){
var phrase = document.forms[fN].elements["phrase"].value;
var letter = document.forms[fN].elements["letter"].value.substr(0,1);
var count = 0;
var temp = phrase;
while(phrase.indexOf(letter.toUpperCase())!=-1){
var pos = phrase.indexOf(letter.toUpperCase())+ 1;
phrase = phrase.substring(pos);
count++;}
while(temp.indexOf(letter.toLowerCase())!=-1){
var pos = temp.indexOf(letter.toLowerCase()) + 1;
temp = temp.substring(pos);
count++;}
document.forms[fN].elements["count"].value = count;}
//-->
</script>
</head>

<body>
<form name="main">
Type your text:<br>
<textarea style="width:100%; height:50%;" name="phrase">
</textarea>
<br>
<input type="text" name="letter">
Letter to search<br>
<input type="button" value="Count" onclick="countLetters('main')"><br>
<input type="text" name="count">
Number of occurances
</form>

</body>
</html>
