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');
});
