Form validation

Topic: Form validation

Belovol pro asked 6 years ago

Good morning! How could I check validity of form's fields from within submitHandler() ? Code here only sets was-validated class to form element, so I can see incorrect input. But I need to make desizion - post data or wait for subsequent correcting input? PS. By the way - something's been broken in this form. There is not confirming message. I've posted one question 6 times yesterday and my IP was banned (so now I use mobile phone). And I'm not alone.

Belovol's answer didn't work for me, but you can call a function reportValidity():

e.target.reportValidity()

This returns true if the form is valid and false otherwise. @staff: would be nice to document this.

Thank you. I'd discovered that there is construction like e.target.validity.valid and it resolves all my troubles.

Form Validation uses html built in validation in association with Bootstraps classes. You can use state to display your custom messages.
