jQuery数组对象，只打印消息键 - jQuery array object to print only message key

jQuery array object to print only message key

本文关键字：打印消息数组对象 jQuery | 更新日期: 2023-09-27

我收到了来自服务器的响应，如何只打印消息在$('#message'(div响应是jsonencoded php

{
  "status":false,
  "message":"<div id='errmsg' class='alert alert-danger'><button type='button' class='btn btn-info pull-right' id='remove'>Remove<'/button><p> Username Is Required<'/p>'n<p> Password Is Required<'/p>'n<p> Name Is Required<'/p>'n<p> Designation Is Required<'/p>'n<'/div>"
}

这是我使用iv 的axax代码

<script type="text/javascript">
    $("#userform").submit(function(e) {
      e.preventDefault();
      var url = $(this).attr('action');
      var formData = new FormData($(this)[0]);
      $.ajax({
           type: "POST",
           url: url,
           data:  formData, 
           processData: false,
           contentType: false,
           success: function(data)
             {
               console.log(data);
               $('#message').html(data.message);                   
             }
         });
});
</script>

如果我尝试data['message']

，我会一直处于未定义状态

您必须在ajax请求选项中传递dataType:'json'，所以jQuery会自动将JSON字符串转换为JSON对象。

<script type="text/javascript">
    $("#userform").submit(function(e) {
e.preventDefault();
    var url = $(this).attr('action');
var formData = new FormData($(this)[0]);
    $.ajax({
           type: "POST",
           url: url,
           data:  formData, 
            processData: false,
        dataType: 'json',
           success: function(data)
           {
            console.log(data);
             $('#message').html(data.message);                     
           }
         });
});
</script>
