在不離開頁面的情況下發送聯系表格和 bootstrapValidator

Question

我正在使用 codepen 中的此代碼作為我的聯系表格。

我遇到的問題是，一旦您單擊“發送”按鈕，您就會離開聯系表單到達的頁面到 sendmessage.php。

我想看到的是表單的正常行為：當您單擊“發送”（並且消息發送成功）時，您停留在同一頁面上，“發送”按鈕消失並被“成功”取代" 消息而無需離開或重新加載放置表單的頁面..

知道當前代碼有什么問題嗎？ 你可以在這里測試我的現場示例

非常感謝，

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');
        });
});

sendmessage.php 的內容：

<?php

require 'PHPMailer/PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->CharSet = 'utf-8';

//Enable SMTP debugging. 
$mail->SMTPDebug = false;                               
//Set PHPMailer to use SMTP.
$mail->isSMTP();            
//Set SMTP host name                          
$mail->Host = "smtp.elasticemail.com";
//Set this to true if SMTP host requires authentication to send email
$mail->SMTPAuth = true;                          
//Provide username and password     
$mail->Username = "xyz";                 
$mail->Password = "xyz";                           
//If SMTP requires TLS encryption then set it
$mail->SMTPSecure = "tls";                           
//Set TCP port to connect to 
$mail->Port = 2525;                                   

$mail->From = $_POST['email'];
$mail->FromName = $_POST['first_name'];

$mail->addAddress("xyz@gmail.com");
//CC and BCC
$mail->addCC("xyz@outlook.com");
$mail->addBCC("");

$mail->isHTML(true);

$mail->Subject = "New message from " . $_POST['first_name'] . $_POST['last_name'];
$mail->Body =  $_POST['message']."<br><br>From page: ". str_replace("http://", "", $_SERVER['HTTP_REFERER']) . "<br>" . $_SERVER ['HTTP_USER_AGENT'] ;

$response = array();
if(!$mail->send()) {
  $response = array('message'=>"Mailer Error: " . $mail->ErrorInfo, 'status'=> 0);
} else {
  $response = array('message'=>"Message has been sent successfully", 'status'=> 1);
}

/* send content type header */
header('Content-Type: application/json');

/* send response as json */
echo json_encode($response);

?>

Answer 1

您是否嘗試過在提交事件中只返回 false？

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

Answer 2

您需要將 bootstrapvalidator.min.js 文件 0.4.5 更新為最新文件

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

我創建了一個小提琴https://jsfiddle.net/nwk9dLrn/8/請檢查但我沒有添加它的 ajax.php 文件，但你可以在控制台中看到它。 當您更新 bootstrapvalidator 文件時，這將起作用。

$('#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'

                    notEmpty: {
                        message: 'Please supply a description of your project'
                    }

            var $form = $(e.target);

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

            // Use Ajax to submit form data

                $("#success_message").show();

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