Question

Hello Everyone我正在创建一个网页来测试我的API，并且我将表单发送到我的nodejs后端，后端将向我返回JSON响应。到目前为止发送请求工作正常，我可以看到请求落在我的VPS控制台上，但我也希望在网页上创建反馈。如何创建包含响应JSON信息的警报？以上是我的代码：

<html>

<body>

  <!-- Always shows a header, even in smaller screens. -->

        <!-- Add spacer, to align navigation to the right -->
        <div class="mdl-layout-spacer"></div>

Answer 1

$(function() {
     $( "#btnOpenMyAspx" ).button().click(function() {           
          $( "#divForAspxPage" ).dialog({            
              autoOpen: true, 
              height: 500,            
              width: 650,
              modal: true,
              close:function(){ 
                   $(this).dialog('destroy');            
              }        
          });           
          $.get("/NewPage.aspx",function(data){               
                $( "#divForAspxPage" ).html(data); 
          });    
    });   
});

这是我用于在对话框中加载页面的技巧，您可以根据需要采用相同的方式，请点击此处http://bresleveloper.blogspot.co.il/2012/05/jquery-modal-dialog-with-aspx-page.html

Answer 2

只需使用javascript的本机alert（）函数。

then(function(data) {
     alert(data);
});

这将创建一个警报框，其中包含来自服务器端的响应。

在Dialog中显示POST响应
