Which type of form validation is used?

AVBScript

BCSS

CJavaScript

DHTML

Show Suggested Answer

Suggested Answer: C

> ''The `onsubmit='return validateForm()'` attribute calls a JavaScript function when the form is submitted. If the function returns `false`, submission is prevented.''

> This is an example of client-side JavaScript validation. VBScript is outdated and IE-specific; CSS is for styling, and HTML-only validation would not use a JavaScript function.

This question seems similar to one we practiced where we had to identify validation methods. I feel like JavaScript is the right choice here.

I'm not entirely sure, but I remember something about HTML forms using JavaScript for client-side validation.

I think the answer might be C) JavaScript since the `onsubmit` attribute is calling a function.
