Regex for 8 digit phone number (Singapore number length)
<p>I'm trying to validate my phone address text field. Can anyone provide me a simple regex to either validate for numeric digits only or a specific 8 digit regex?</p>

<p>Much thanks!</p>

<pre><code>$('#phone').on('input', function() {
var input = $( this );
var regex = /* regex needed here */
var is_phone = regex.test(input.val());
if (is_phone){input.removeClass("invalid").addClass("valid");}
else {input.removeClass("valid").addClass("invalid");}
});
</code></pre>
