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

Both onclick and onsubmit do the same thing. No matter you press enter on a text input element or press submit button, both are triggered. If you use both onclick and onsubmit events, they are both executed respectively. And if You have more than one submit buttons in the form, the first submit button's onclick method is executed. Tested on Internet Explorer, Firefox, Chrome and Opera.

Answer 2

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.
