Bootstrap Modal中的JQuery验证表单在验证后不会提交

Question

UPDATE: To put the question into perspective I created another Fiddle that shows the same form outside of the modal.

When it meet the right conditions i.e you type an email address and hit the Get Started button it submits properly display the PHP page, in this case it shows a 404 error, but it does what is supposed to do, SUBMIT!

ORIGINAL PROBLEM: Now back to the problem: I would like to submit my form inside a bootstrap modal, but when I open the modal and type an email, and press the get started button: NOTHING HAPPENS

What am I doing wrong? Is there a JavaScript solution missing to submit the form correctly or are the validation errors interfering?

I'm a novice in JavaScript so I can't seem to figure out the coding solution if it's in fact js based.

Please help me figure this strange modal issue, thank you!

HTML:

<form id="signup-form" class="cd-signin-modal__form" action="confirm.php" method="post">
                <h3 class="bigsentence black text-center font-weight-bold">Create</h3>
                <p class="cd-signin-modal__fieldset">
                    <label class="cd-signin-modal__label cd-signin-modal__label--email cd-signin-modal__label--image-replace" for="signup-email">Enter your email address</label>
                    <input class="cd-signin-modal__input cd-signin-modal__input--full-width cd-signin-modal__input--has-padding cd-signin-modal__input--has-border signupfield" id="email" type="email" name="email" placeholder="Enter your email address">
                </p>

                <p class="cd-signin-modal__fieldset">
                    <input class="cd-signin-modal__input cd-signin-modal__input--full-width" name="submit" type="submit" value="GET STARTED">
                </p>
            </form>

JS:

$("#signup-form").validate ({

    // validation rules for registration formd
errorClass: "error-class",
validClass: "valid-class",
errorElement: 'div',
errorPlacement: function(error, element) {
    if(element.parent('.input-group').length) {
        error.insertAfter(element.parent());
    } else {
        error.insertAfter(element);
    }
},
onError : function(){
    $('.input-group.error-class').find('.help-block.form-error').each(function() {
      $(this).closest('.form-group').addClass('error-class').append($(this));
    });
},
        rules: {
    email: {email:true, required:true}
  },

    messages: {
        email: {
            required: "Please enter your email address",

        },


            highlight: function(element, errorClass) {
    $(element).removeClass(errorClass);
}    
    }

});

Your code is missing two things

Add this in signup-form validator

submitHandler: function(frm) { 
    frm.submit();
}

Then in signup-form remove

name="submit"

from

<input class="cd-signin-modal__input cd-signin-modal__input--full-width" name="submit" value="GET STARTED" type="submit">

You can read the explanation here javascript submit() is not a function?
