Question

I have this form in my app and I will submit it via AJAX, but I want to use HTML for client-side validation. So I want to be able to force the form validation, perhaps via jQuery.

I want to trigger the validation without submitting the form. Is it possible?

Answer 1

To check whether a certain field is valid, use:

$('#myField')[0].checkValidity(); // returns true|false

To check if the form is valid, use:

$('#myForm')[0].checkValidity(); // returns true|false

Show html5 built-in error

if (! $('#myForm')[0].checkValidity()) {
      $('#myForm')[0].reportValidity()
}

Keep in mind that, HTML5 validation is not supported in all browsers till now.
