how to allow use of a specific character - REGEX : <p>I'm actually using this code to check if my string have any special characters:</p>

<pre><code>var regex = /[^\w\s!?]/g;

if (regex.test(message)) {
   notify('error', 'Special characters are not allowed!');
   return;
}
</code></pre>

<p>but I want to allow '/' too.</p>
