Hello: I could use some help. I have a form where I'm having people enter URL's into textboxes that should not contain URL's. How can I write a form validation script where I can check that each textbox field does NOT have a URL in it? For example, the phone number textbox field should only accept a valid phone number (###) ###-####. The name textbox field should only contain letters (no numbers or characters). Can someone help me write something? Thank you. |
