$(document).ready(function(){
var a=['bad','worse'];
for(var i=0; i<a.length; i++){
var re = new RegExp(a[i],"g");
var str = "bad words here";
var res = str.match(re);
if(res.length>0){
alert(res);
break;
}
}
});

Try this:
return "";
This is the only way that you will ever stop people from using words you don't like: don't allow them to use any words at all.
Even if you detect certain words, you will have many problems with it, many of which were given to you in a comment on your question. Swapping characters like in @$$ is all too common, and the nerdier people will know about the Cyrillic characters that look identical to Latin characters - try detecting sеx with your regex!
It is infinitely more efficient to take a more social approach to this problem. If your community is disinclined to post such words, then there's no need to worry about it. If you moderate the rare posts that contain such words, then the perpetrator won't be able to do it again and others may think twice before following in their footsteps. I have never had any word filters on my user-submitted content, and while we do get the occasional potty-mouth, they're always super-fast to deal with instead of the many hours that would go into trying to stop them in the first place.
