Should I use the input's onclick or the form's onsubmit event to validate form fields using JavaScript?

Question

I have a simple form with fields that I am trying to validate using JavaScript. In the form I have an input type of submit.

For validation, should I call the val

Answer 1

onsubmit is triggered whenever the form is about to be submitted.
onclick is triggered when the specific button is clicked.

Forms can be submitted by hitting the enter key in any input field. This would not trigger the onclick of the submit button, but it would trigger the form submit event. As such, use onsubmit.
