Hi I'm new here hopefully I can contribute as time goes on. I working on making a simple tag cloud for work and cant seem to get rid of the commas in my array.

here's the code:
HTML Code:
<script type="text/javascript">
var s = document.getElementById("input").value;
				var punct_less = s.replace(/[\.,-\/#!$%\^&\*;:{}=\-_`~()]/g,"");
				var finalString = punct_less.replace(/\s{2,}/g,"");
				var split = new Array();	
				split = finalString.split(" ");
				split.sort();
				var diff = unique(split);
				document.getElementById("display").innerHTML = diff;
</script>
When it prints out it goes as such: orange,banana,apple,

I tried a replace after the unique function that only displays non-duplicates but it doesn't seem to be working....any thoughts
