I was using Jquery Numeric plugin but I found that is not working on FireFox 3.6 on Osx (does not allow pasting).
I\'m searching a Jquery plugin or Javascript snippet
Thanks systempuntoout.. I've fixed this with following script
$('#input').keyup( function() { var $this = $(this); $this.val($this.val().replace(/[^\d.]/g, '')); });
