Question

我使用Bootstrap 4和PHPMailer创建了一个表单提交，在我添加一些jQuery尝试显示警告框以显示成功或失败之前，该表单一直运行良好。

                         <div id="messages" class="hide" role="alert">
          <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
          <div id="messages_content"></div>
        </div>


                        <form id="form" role="form" action="test.php" method="post" enctype="multipart/form-data" class="form">
                            <div class="row">
                                <div class="col-md-3">
                                    <label class="input-group g-rounded-3 g-mb-0--md">

                                        <div class="input-group-append">

                                <div class="col-md-3">

                                </div>
                                <div class="col-md-4">
                                    <select class="custom-select w-100 mr-sm-3 mb-3 mb-lg-0 border border-secondary" id="inlineFormCustomSelect" name="service">

                                <div class="col-md-2">

                            </div>
                        </form>

                  </section>


                </div>
            </div>
        </section>



        <script src="http://code.jquery.com/jquery.js"></script>
    <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

    <script>
        $('#form').submit(function(e) {
            $('#messages').removeClass('hide').addClass('alert alert-success alert-dismissible').slideDown().show();
            $('#messages_content').html('<h4>MESSAGE HERE</h4>');
            $('#modal').modal('show');
            e.preventDefault();
        });
    </script>`

提交表单后，将显示警告框，其中文本字段将保持填充状态（显然不会在任何地方发送）并且不会接收电子邮件。

如果我删除了jQuery，则将表单发送到php文件，进行处理并返回该页面，并收到电子邮件。我似乎找不到此特定问题，我看不到该问题！

Answer 1

问题出在jQuery的底部：

e.preventDefault();

这防止了表单提交事件的默认操作，因此表单不会提交。删除此行，它将起作用。

jQuery正在阻止表单提交
