Re: [Flashcoders] String Empowerment
Hi Steven,
Maybe i'm saying something stupid here, but would this be a prettier
way to do the capitalize?
String.prototype.capitalize = function() {
return this.charAt(0).toUpperCase() + this.substr(1).toLowerCase();
}

Some methods are still in development - some pretty tricky

arguments to be passed with the intersections of those strings

Don't use the toLowerCase() Because when I write my name like: Bernard Visscher I don't want the output to be Bernard visscher with the lowercase V. That's what capitalize() does.

RE: [Flashcoders] String Empowerment
Maybe you can do something with this.
It's an implemenataion of the Damerau-Levenshtein distance.
The output is equal to the minimal number of insertions, deletions,
substitutions and transpositions needed to transform one string into the
other.
Could be handy for a spellchecker...
It's not optimized, just wrote it a few days ago for testing...
private static function compare(first:String, second:String):Number
{
if(first == || second == ) return null;
var f:Array = first.split();
var s:Array = second.split();
var dist:Array = new Array();
for(var i:Number = f.length+1 ; i--)
{
dist[i] = new Array();

RE: [SPAM] RE: [Flashcoders] String Empowerment
Just a quick note on capitalize() String.toUpperCase() and String.toLowerCase() are part of ActionScript 1 since Flash 5 Capitalize is different than toUpperCase and toLowerCase. Those convert the entire string, capitalize only uppercases the first character and then lowercases the rest of the characters. ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

RE: [SPAM] RE: [Flashcoders] String Empowerment
If you REALLY wanted to be fancy, you could have it accept an array of words *not* to capitalize (unless they are the first word). For example: var lowerCaseWords:Array = [a, an, and, of, the]; trace(a tale of two cities.toTitleCase(lowerCaseWords)); trace(THE PRINCE AND THE PAUPER.toTitleCase(lowerCaseWords)); // Output: // A Tale of Two Cities // The Prince and the Pauper -- T.

Here's toTitleCase:
String.prototype.toTitleCase = function() {
var a = this.length;
if (a == 0) return ;
var c;
var w;
var s = ;
while (--a -(-1)) {
c = this.charCodeAt(a);
w = this.charAt(a - 1);
w = (w == || w == \n || w == \r || w == \t ||

s = String.fromCharCode(c) + s;
