Alright, I'm using a Rooh.It WordPress plugin right now, but I don't like the way they do it, so I want to write my own code to do something similar.
I want the user to be able to select the text they want to highlight, and the background color of that text changes to whatever color they have selected.
This ought to move you forward. You can use css to change the background color the .highLight selector from background-color:#ff9900; (but what is meant by "whatever color they have selected"?).
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
var count = 0;
var itemList = new Array();
var oldText = "";
var rawText = "";
var workText = "";
function highlight() {
// overcome problem in Firefox caused by blank fields
itemList[0] = document.getElementById("txt1").value == '' ? "FireSchmoxStryng" : document.getElementById("txt1").value;
itemList[1] = document.getElementById("txt2").value == '' ? "FireSchmoxStryng" : document.getElementById("txt2").value;
itemList[2] = document.getElementById("txt3").value == '' ? "FireSchmoxStryng" : document.getElementById("txt3").value;
if (count == 0) {
rawText = document.getElementById('subjectMatter');
workText = rawText.innerHTML;
oldText = rawText.innerHTML;
}
else {
workText = oldText;
}
workText = workText.replace(/(\<)/g," $1").replace(/(\>)/g,"$1 ");
for (i=0; i<itemList.length; i++) {
itemList[i]= itemList[i].replace(/^\s+|\s+$/g,"");
var currWord = new RegExp("([\\s\\r\\n\(]*"+itemList[i]+"[\\s,;\.:?!\'\"()-]+)",'gi');
workText = workText.replace(currWord," <span class='highLight'>$1<\/span> ");
}
//for (i=0; i<itemList.length; i++) {
//var currWord = new RegExp("(\<\/span\>\\s)([0-9a-z%,;:\.?!\"\'()]+\\s)",'gi');
//workText = workText.replace(currWord," $1<span class='highLight'>$2<\/span> ");
//}
//for (i=0; i<itemList.length; i++) {
//var currWord = new RegExp("(\\s[0-9a-z%,;.:?!'()]+)(\\s\<span class='highLight'>)",'gi');
//workText = workText.replace(currWord," <span class='highLight'>$1<\/span>$2 ");
//}
rawText.innerHTML = workText;
count ++;
}
</script>

Q. If you were to spell out numbers, how far would you have to go until you would find the letter "A"?
A. One thousand
It is a fun question. A surprising answer in English if you've never thought about it before. Of course, some people say "one hundred AND one", but we'll delegate them to English grammar hell.
