ios 不支持iframe 解决方案

在iframe外层在包一层，通过appendChild()把内容增加到容器中，完整代码如下：

 1 @section Css
 2     {
 3     <link href="@ViewHelper.Content("/Content/css/mobiscroll.css")" rel="stylesheet" type="text/css" />
 4     <link href="@ViewHelper.Content("/Content/css/common.css")" rel="stylesheet" />
 5 }
 6 <style>
 7     .frame {
 8         margin-top: 55px;
 9         padding: 10px;
10         height: 90vh;
11         width: 100vw;
12         border: none;
13     }
14 </style>
15 <div id="iframe-box">
16     <iframe id="ifram" class="frame" width="420" height="330" src="@ViewBag.PathUrl.Replace("http://","https://")"></iframe>
17 </div>
18 @section Js{
19     <script>
20         var ifram = document.getElementById(\'ifram\');
21         if (navigator.userAgent.match(/iPad|iPhone/i)) {
22             var iframe_box = document.getElementById(\'iframe-box\');
23             iframe_box.style.width = 100 + \'%\';
24             iframe_box.style.overflowX = \'hidden\';
25             iframe_box.style.overflowY = \'scroll\';
26             iframe_box.style.webkitOverflowScrolling = \'touch\';
27             ifram.setAttribute(\'scrolling\', \'no\');
28             iframe_box.appendChild(ifram);
29         }
30     </script>
31 }
