Question

我创建了一个带有ajax函数的页面，用于将数据插入到数据库中，所以点击提交数据就会在数据库中插入，但我想显示一条消息，说明数据是否已插入到已创建的div并显示结果在那，但我看不到文字。

Answer 1

以下是您的代码的更新部分。表格重置代码已添加。

$.ajax({
    type: 'POST',
    url: 'addPost.php',
    data: $('#postForm').serialize(),
    success:function(report){
         // replace data to report
         $(".result").html(report);

         //reset form
         $(':input','#form') 
            .not(':button, :submit, :reset, :hidden') 
            .val('') 
            .removeAttr('checked') 
            .removeAttr('selected'); 
    }
});

请在服务器端和客户端之间制定合同

例如：每当客户端向服务器发送请求时服务器处理请求，为这些行构建响应 - 例如（{result：“success”}或某些内容并将其发送回客户端客户端将能够在$ .ajax的成功中访问它客户现在将根据合同了解何时成功以及何时失败并执行下一步操作

希望这有帮助。
