I need to make it so a user can ONLY type a-z0-9 into my input box. How can I make it so the user simply cannot type other characters? If this isn’t possible, how can I simply check the input with regex?
Thanks!

Another notable solution is this alphanumeric plugin for jquery:

Simple as
$('#textField').alphanumeric();
