AS3 :: StringUtils Class
Submitted by hasan on Thu, 10/05/2006 - 07:00.
Came up with this idea after perusing proto.layer51.com. It's basically a sub-class of String and the 1st method is a reduction method that let's you feed in a string, a limit and a "there's more" indicator. Anyways, here's the code:
class labs.otuome.utils.StringUtils extends String
{
public var theString:String;
public function StringUtils(string:String)
{
super();
theString = string;
}
public function reduce(stringLength,trimIndicator):String
{
var trimmedString:Array = [];
if (theString.length < = stringLength)
{
//just return the string if it's within the "limit"
return theString;
}
var words:Array = theString.split(" ");
var numWords:Number = words.length;
var ol:Number = 0;
var cWord:String;
var w:Number;
for (w=0; w<numWords; ++w)
{
cWord=words[w];
var cwl=cWord.length;
//check each words length before adding it the output string
if ((ol+cwl)<=stringLength)
{
trimmedString.push(cWord);
ol+=cwl+1;
}
else break;
}
return trimmedString.join(" ")+trimIndicator;
}
}
