how can I do a jQuery swear word / bad word filter?

Question

I know there are many arguments as to why this is a bad idea, but in my implementation I\'m planning on enabling/disabling bad words in the account settings. In other words

Answer 1

Something like this might work:

String.prototype.repeat = function(num){
  return new Array(num + 1).join(this);
}

var filter = ['ass', 'piss'];

$('.post').text(function(i, txt){

  // iterate over all words
  for(var i=0; i

Working example on jsFiddle

Edit: Added boundaries so it won't replace words that contain the swear words. I've used double backslashes because backslashes should be escaped in a string, see this topic.
