Which form input validation method is sometimes referred to as pogo-sticking?

• A. Requiring users to click Submit before validation occurs
• B. Live validation on every keystroke
• C. Validation after form submission
• D. External validation

Answer: (A)

Pogo-sticking here is about the friction from validation that only happens after you submit, forcing a back-and-forth flow between typing and clicking the submit button. When you must click Submit to see validation results, you type in the form, press submit, read the errors, fix them, and then press submit again to test the fixes. that cycle—type, submit, see errors, fix, submit again—feels like you’re bouncing back and forth, much like a pogo stick. That repetitive submission-driven feedback is the signature of pogo-sticking, which makes the process slower and frustrating.

Live validation on every keystroke avoids this by giving immediate feedback as you type, so you can correct issues without having to resubmit. Validation only after submission still works, but it doesn’t create that repeated back-and-forth as clearly as the submit-driven cycle does. External validation isn’t about the user interaction timing in the form itself.
