我有以下代码:

$.ajax(
        {
            url: rootPath + "Framework/GetPartial",
            data: { partialName: partialName },
            type: "POST",
            success: function (response)
            {
                $('#loading').hide();
                $('#partialContent').hide().html(response).fadeIn();
            },
            error: function (xhr, textStatus, errorThrown)
            {
                $('#loading').hide();
                $('#partialContent').hide().html('An error occurred. Details below:<br /><br />' + xhr.responseText).fadeIn();
            }
        });

我关心的是错误处理函数。当服务器发生错误时，将发送一个包含详细调试信息的 html 页面作为响应。我想将此 html 响应加载到现有页面中，但包含 <HTML> , <HEAD> , 和 <BODY>响应中的标签会破坏整个页面的格式。我如何在以下 HTML 响应中使用 JQuery 仅解析 body 标记中的内容？

<html>

    <head>

        <title>The method or operation is not implemented.</title>

        <style>

         body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;} 

         p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px}

         b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px}

         H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red }

         H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon }

         pre {font-family:"Lucida Console";font-size: .9em}

         .marker {font-weight: bold; color: black;text-decoration: none;}

         .version {color: gray;}

         .error {margin-bottom: 10px;}

         .expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }

        </style>

    </head>



    <body bgcolor="white">



            <span><H1>Server Error in '/AlexAndNikki' Application.<hr width=100% size=1 color=silver></H1>



            <h2> <i>The method or operation is not implemented.</i> </h2></span>

编辑:

有没有办法将响应字符串加载到 iframe 中？如果可能的话，那就太好了。

类似于:

$('#partialContent').html('<iframe>' + xhr.responseText + '</iframe>');

显然我试过这段代码但没有用，但也许有人知道如何制作 iframe 来解决问题？

最佳答案

你可以这样做:

$('#partialContent').hide().html($('body',response).contents()).fadeIn();

这是 .empty().append() 的快捷方式在下面，但主要部分是 $('body',response) ，正在寻找 <body>响应中的元素，然后将其内容作为要追加的元素。
