dojo.io.iframe.send 获得返回数据

阅读更多

使用dojo.io.iframe.send提交表单时发现老是取得不了返回的response,找了半天才发现是这个原因:

 

  • IMPORTANT: For all values EXCEPT html, The server response should be an HTML file with a textarea element. The response data should be inside the textarea element. Using an HTML document the only reliable, cross-browser way this transport can know when the response has loaded. For the text/html mimetype, just return a normal HTML document. NOTE: text/xml or any other XML type is NOT supported by this transport.

就是说返回的内容必须写在 textarea里面,像下面这样:

<html>
  <body>
    <textarea>
      payload
    </textarea>
  </body>
</html>

而且返回的mime type应该是“text/plain”不能是"text/xml"之类的XML mime类型。使用java来表示就是:

 

response.setContentType( "text/plain;charset=UTF-8" );
