Input field custom validation question

Is there a way to validate if two input fields content are identical?

In my form I would like to include two fields:

email
email again

and validate if the two fields content are the same, before allowing submit. I whish to prevent the user from submitting, if the two email addresses differ.

Is there any to enforce this validation? Thank you for your time in advance.
