JavaScript bit:

$(document).ready(function()
    {
            $('#form').submit(function(e)
            {     

                e.preventDefault();
                var $form = $(this);

                // check if the input is valid
                if(! $form.valid()) return false;
                    $.ajax(
                    {
                    type:'POST',
                    url:'add.php',
                    data:$('#form').serialize(),
                    success:function(response)
                    {
                        $("#answers").html(response);
                    }
                });     

            })
    });

HTML bit:

    <input type="text" name="answer[1]" class="required" />
    <input type="text" name="answer[2]" class="required" />

So this is the code I am trying to use. The idea is to get all my inputs validated before I send my form with Ajax. I've tried numerous versions of this now but every time I end up with submitting even though the form is not entirely filled out. All my inputs are of the "required" class. Can anyone see what I am doing wrong?

Also, I depend on class-based requirements as my input names are generated with php so I can never be sure what name[id] or input types I get.

I show/hide questions as I go through it in "pages".

<input type="button" id="next" onClick="toggleVisibility('form3')" class="next-btn"/>

JS:

function toggleVisibility(newSection) 
        {
            $(".section").not("#" + newSection).hide();
            $("#" + newSection).show();
        } 

You could use the submitHandler option. Basically put the $.ajax call inside this handler, i.e. invert it with the validation setup logic.

$('#form').validate({

    ... your validation rules come here,

    submitHandler: function(form) {
        $.ajax({
            url: form.action,
            type: form.method,
            data: $(form).serialize(),
            success: function(response) {
                $('#answers').html(response);
            }            
        });
    }
});

The jQuery.validate plugin will invoke the submit handler if the validation has passed.

jQuery validation before AJAX submit, I think you should have to remove the onsubmit event from your form tag and write the below script in document.ready() Using the same technology, we have already discussed about type validation.

first you don't need to add the classRules explicitly since required is automatically detected by the jquery.validate plugin. so you can use this code :

  1. on form submit , you prevent the default behavior
  2. if the form is Invalid stop the execution.
  3. else if valid send the ajax request.

    $('#form').submit(    function(e){     
    
                e.preventDefault();
                var $form = $(this);
    
              // check if the input is valid
                if(! $form.valid()) return false;
    
               $.ajax({
                    type: 'POST',
                    url: 'add.php',
                    data: $('#form').serialize(),
                    success: function(response) {
                        $("#answers").html(response);
                    }
    
                });
            });

This specific example will just check for inputs but you could tweak it however, Add something like this to your .ajax function:

beforeSend: function() {

        return this.value === "";
