Verify form validation

Question

Hello, I have a form that I want to run through form validation, and then submit. How can I check if the following function returns true in order to know that everything has been checked and then sent?

I created a script for testing

            $(function(){

            debug: false,
            rules: {
                name: "required",
                email: {
                    required: true,
                    email: true
                        },
                phone: {

                    phone: true
                        }
                    },
            messages: {
                name: "Please let us know who you are.",
                email: "A valid email will help us get in touch with you.",
                phone: "Please provide a valid phone number.",
            }
        })  


    $('#form').submit(function(e){
        // Stop the form actually posting
        e.preventDefault();




        // I want to be able to do the check here if the form has passed validation
        if( $(this).valid() ) {
        // Stop the form actually posting

        // Send the request
        $.post('/submit.php', {
            name: $('#name').val(),
            email: $('#email').val(),
            phone: $('#phone').val(),
            message: $('#message').val()
        }, function(d){
            alert("Thank you for submitting your request someone will contact your shortly.");
        });
        }
    });
});
    </script>

Answer 1

You can call the valid () method to validate jquery. how

if($('#form').valid())

In fact, you can declare a validate function when loading an html page and just check if it is valid or not during submission

$(document).ready(function(){

$('#form').validate(rules...messages...);

In case of using rules and messages: -

  rules: {
            name: {
               required: true  
            },
            email: {
                required: true,
                email: true
                    },
            phone: {
                required: true,
                phone: true                       }
                },
        messages: {
            name: { required : "Please let us know who you are."},
           email: {required : "A valid email will help us get in touch with you.",email : "A valid email will help us get in touch with you."},
            phone: {required:"Please provide a valid phone number.",phone:"Please provide a valid phone number."}
        }

, .

$('#form').submit(function(evt) {
    evt.preventDefault();

    .....

    if( $('#form').valid() ) {
       //submit the form via ajax
    } else {
       //show errors
    }
 });

});

, , : -

 <input type="text" name="email" />
