Question

我通过链接向servlet发送请求，并希望通过此链接的html代码接收响应。 Servlet接收链接，处理它并发送html代码作为响应，但我无法用ajax接收它。

请求＆amp; servlet中的响应 - 它工作正常！

  <title></title>

<body >

  <div height="60%">

  <script type="text/javascript">
$("#submitForm").submit(function(){
      console.log("onclick");
      var url = $("#url").val();
      $.post('proxyServer', {url: url}, function(responseText) {
        console.log("text received");
        var iframe = document.getElementById('FileFrame');
        var iframedoc = iframe.document;
        if (iframe.contentDocument)
          iframedoc = iframe.contentDocument;
        else if (iframe.contentWindow)
          iframedoc = iframe.contentWindow.document;
        if (iframedoc) {
          //iframedoc.open();
          iframedoc.write(responseText);
          iframedoc.close();
        } else {
          alert('Cannot inject dynamic contents into iframe.');
        }
        }).error(function(p1, p2, p3){
        alert("error!");
        console.log(p1 + p2 + p3);
      });
    });
  </script>
</div>
</body>
</html>
