Disable input dot '.' javascript
<p>I'm trying to disable user for input dot <code>.</code>. Here is what I try so far</p>

<pre><code>$('#num').on('input', function (event) { 
    this.value = this.value.replace(/^[0-9]+\.?[0-9]*$//./, '');
});
</code></pre>

<p>with my script above, I still can input dot <code>.</code>. Is there anyway to prevent user to input dot <code>.</code> ?</p>

<p>thanks in advance, and sorry for my bad english.</p>
