在不离开页面的情况下发送联系表格和 bootstrapValidator

Question

I'm using this code from codepen for my contact form.

The issue that I'm experiencing is that once you click the "send" button, you leave the page where the contact form is to arrive to sendmessage.php.

What I'd like to see is the normal behavior of a form: when you click "send" (and the message is transmitted successfully), you stay on the same page, the "send" button disappears and is replaced by the "success" message without leaving or reloading the page where the form is placed..

Any idea what the issue is with the current code? You can test my live example here

Many thanks,

HTML:

<form class="well form-horizontal" action="../sendmessage.php" method="post"  id="contact_form">

Javascript:

  $(document).ready(function() {
    $('#contact_form').bootstrapValidator({
        // To use feedback icons, ensure that you use Bootstrap v3.1.0 or later
        feedbackIcons: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            first_name: {
                validators: {
                        stringLength: {
                        min: 2,
                    },
                        notEmpty: {
                        message: 'Please supply your first name'
                    }
                }
            },
            email: {
                validators: {
                    notEmpty: {
                        message: 'Please supply your email address'
                    },
                    emailAddress: {
                        message: 'Please supply a valid email address'
                    }
                }
            },            
            message: {
                validators: {
                      stringLength: {
                        min: 10,
                        max: 200,
                        message:'Please enter at least 10 characters and no more than 200'
                    },
                    notEmpty: {
                        message: 'Please supply a description of your project'
                    }
                    }
                }
            }
        })
        .on('success.form.bv', function(e) {
            $('#success_message').slideDown({ opacity: "show" }, "slow") // Do something ...

                $('#contact_form').data('bootstrapValidator').resetForm();

            // Prevent form submission
            e.preventDefault();

            // Get the form instance
            var $form = $(e.target);

            // Get the BootstrapValidator instance
            var bv = $form.data('bootstrapValidator');

            // Use Ajax to submit form data
            $.post($form.attr('action'), $form.serialize(), function(result) {
                console.log(result);
            }, 'json');
        });
});

Answer 1

Have you tried doing just returning false on the submit event?

$('#contact_form').on('submit', function(event) {
  event.preventDefault();
  return false;
});

Answer 2

You need to update your bootstrapvalidator.min.js file 0.4.5 to latest file

https://cdnjs.cloudflare.com/ajax/libs/jquery.bootstrapvalidator/0.5.3/js/bootstrapValidator.min.js

I have created a fiddle https://jsfiddle.net/nwk9dLrn/8/ plz check but i have not added its ajax.php file but you can see it in console. when you update your bootstrapvalidator file this will work.

$('#contact_form').bootstrapValidator({
        // To use feedback icons, ensure that you use Bootstrap v3.1.0 or later
        feedbackIcons: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            first_name: {
                validators: {
                        stringLength: {
                        min: 2,
                    },
                        notEmpty: {
                        message: 'Please supply your first name'
                    }
                }
            },
            email: {
                validators: {
                    notEmpty: {
                        message: 'Please supply your email address'
                    },
                    emailAddress: {
                        message: 'Please supply a valid email address'
                    }
                }
            },            
            message: {
                validators: {
                      stringLength: {
                        min: 10,
                        max: 200,
                        message:'Please enter at least 10 characters and no more than 200'
                    },
                    notEmpty: {
                        message: 'Please supply a description of your project'
                    }
                    }
                }
            }
        })
        .on('success.form.bv', function(e) {
            // Prevent form submission
            e.preventDefault();

            // Get the form instance
            var $form = $(e.target);

            // Get the BootstrapValidator instance
            var bv = $form.data('bootstrapValidator');

            // Use Ajax to submit form data
            $.post($form.attr('action'), $form.serialize(), function(result) {                
                $("#success_message").show();

                $('#contact_form input').val('');
            }, 'json');
        });
