JavaScript - General

This is to truncate multiple items in the javascript library Prototype. If it has the it will be truncated! Simple way:

var TruncateIt = Class.create({ 
  initialize: function(sTruncate){ 
    var toTruncate = (typeof sTruncate != 'undefined') ? $$(sTruncate) : $$('.truncate'); 
    var len = 100; 
    for (var i = 0; i < toTruncate.length; i++) { 
      toTruncate[i].innerHTML = toTruncate[i].innerHTML.truncate(len); 
    } 
  } 
}); 
document.observe('dom:loaded', function(){ 
  var truncate = new TruncateIt('.truncate'); 
}); 
 

Thanks to Kris for helping me write this in a class as I'm totally new to prototype. See his hip new site at komputerart.com.
