REGEX That Doesn't Allow Spaces or Special Characters

Salutations, I need a regular expression in which doesn't allow spaces or special characters. All replies are appreciated. Thank you.

For example, if somebody enters $cdIAb!%, a bcd, or $ab%c d@, it would be rejected. If they entered cdIAb it would be accepted.

This is for an Xenforo forum.

Solution

  • The regex express you would use is ^(\d|\w)+$: 

    <form>
  <input type="text" pattern="^(\d|\w)+$">
  <button type="submit">submit</button>
</form>
