onkeyup="this.value=this.value.replace(/[^0-9] /g,'')";

Hi guys, hope you can help me out with this one, I am using the code below to let the user only input numbers, thing is he must be able to add dots as wel like 9.99
somehow adding the dot and / or escaping it won't work, any ideas?

onkeyup="this.value=this.value.replace(/[^0-9.] /g,'')";

onkeyup="this.value=this.value.replace(/[^0-9\.] /g,'')";
