Javascript Ajax电子邮件和密码验证不断返回错误结果

我对ajax电子邮件和密码验证有问题。我不知道控制器和模型有什么问题，因为当我删除

e.preventDefault（）时返回正确的结果。为什么ajax代码总是返回false？这是因为我使用MD5 type作为密码还是这件事
数据：“email=“+email+”&“+”password=“+password，
不正确

JS

看法

尝试这样做。以对象格式发送数据
{}
。并使用
JSON.parse（）
解析JSON响应

<script type="text/javascript">
    $(document).ready(function(){

    $('#myform').on('submit', function(e) {
    // e.preventDefault();        //<---- stop submiting the forms
    var email = $('#email').val();
    var password = $('#password').val();
    $.ajax({
        type: "POST",
        url: "<?php echo base_url('KulinerControl/otentikasi');?>",
        dataType: "json",
        data: {email:email,password:password},                   
        success: function(response){
            var data = JSON.parse(response)//or data = eval(response);
            if(data.valid){
                $('#msg').html(data.msg);
                // $("#myform").submit();    //<---- submit the forms
            }else{
                $('#msg').html(data.msg);
            }
        }
    });
});
});
</script>

或者在
application/config/autoload.php

你的观点一定是这样的

<?php echo form_open('', array('id'=>'myform')); ?>
<span id="msg"> </span> 
    <label for="email>Email</label>
    <input type="text" name="email" id="email" required> 
    <label for="password"  >password</label>
    <input type="password" name="password" id="password" required> 
    <button type="submit" >Submit</button>
</form>


在js中，您可以通过
$（'#email'）.val（）获取值和
$（“#密码”）.val（），但您尚未指定两个输入字段的id属性。因此，根据需要在两个输入中添加id属性

<?php echo form_open('KulinerControl/otentikasi', 'id="myform"'); ?>
<span id="msg"> </span> 
    <label for="email>Email</label>
    <input type="text" name="email" id="email" required> 
    <label for="password"  >password</label>
    <input type="password" name="password" id="password" required> 
    <button type="submit" >Submit</button>
</form>

您可以尝试
data:$（“#myform”）.serialize（）
