重置密码功能无效

Question

我创建了一个密码重置功能，当用户输入他的id时它会工作，然后将id插入到查询中以查找用户的密码。找到密码后，密码将被发送到用户邮箱。 从用户ID获取的电子邮件。但我的功能不起作用，我没有收到任何错误信息，所以我不知道我的代码有什么问题。

- 这是我的观点 -

    <!-- Modal Body -->
    <div class="modal-body">
        <p class="statusMsg"></p>
        <form role="form" id="formPass" action='<?php echo base_url() ?>kirim_form' method="post">
            <div class="form-group">
                <label for="masukkanNpk">Masukkan NPK:</label>
                <input type="text" class="form-control" id="npk" placeholder="Masukkan NPK Anda"/>
            </div>
        </form>
    </div>

    <!-- Modal Footer -->
    <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Tutup</button>
        <button type="button" class="btn btn-primary submitBtn" onclick="kirimContactForm()">KIRIM</button>
    </div>

- 用户提交ID后，这是我的功能 -

    }


   }
 ?>

- 这是一些javascript -

function kirimContactForm(){
    var reg = /^[A-Z0-9._%+-]+@([A-Z0-9-]+\.)+[A-Z]{2,4}$/i;
    var npk = $('#npk').val();
    // var email = $().val();
    if(npk.trim() == '' ){
  alert('Masukkan NPK Anda.');
        $('#npk').focus();
  return false;
 }else{
        $.ajax({
            type:'POST',
            url:$('#formPass').attr('action'),
            data:'contactFrmSubmit=1&npk='+npk,
            beforeSend: function () {
                $('.submitBtn').attr("disabled","disabled");
                $('.modal-body').css('opacity', '.5');
            },
            success:function(msg){
                if(msg == 'ok'){
                    $('#masukkanNpk').val('');
                    $('.statusMsg').html('<span style="color:green;">Password akan dikirimkan ke email:' , '<br><br> Jika tidak menerima email harap menghubungi helpdesk di <u>021-75998699</u></p>');
                }
                else{
                    $('.statusMsg').html('<span style="color:red;">Mohon Maaf email anda tidak ada di sistem ITCare. Password akan dikirim ke atasan anda di:', '<br><br>Jika tidak menerima email harap menghubungi helpdesk di <u>021-75998699</u> </span>');
                }
                $('.submitBtn').removeAttr("disabled");
                $('.modal-body').css('opacity', '');
            }
        });
