jquery文件上传dataType脚本IE问题

Question

我在使用 jquery fileupload 插件时仍然遇到问题，仅在 IE 上。

JavaScript 是这样的:

$('input#fileupload').fileupload({
    url: '/upload_attachment.js',
    dataType: 'script',
 ................
 ................

$('input#realupload').bind('change', function(e){
   $('#fileupload').fileupload('send', {
    dataType: 'script',
    files: e.target.files || [{name: this.value}],
    fileInput: $(this)
 }); 
 e.preventDefault();       
});

这是请求 header :

 Key    Value
 Request    POST /holdings/183400184/upload_attachment HTTP/1.1
 Accept text/html, application/xhtml+xml, */*
 Referer    http://192.168.1.209:3000/holdings/183400184
 Accept-Language    en-NZ
 User-Agent Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
 Content-Type   multipart/form-data; boundary=---------------------------7dc1d02610132

 Host   192.168.1.209:3000
 Content-Length 196

我将数据类型指定为:“script”，然后从服务器返回:

 Key    Value
 Response   HTTP/1.1 200 OK 
 Content-Type   text/javascript; charset=utf-8
 Cache-Control  max-age=0, private, must-revalidate
 X-Ua-Compatible    IE=Edge

 Date   Wed, 25 Jan 2012 02:52:48 GMT
 Content-Length 345
 Connection Keep-Alive
 Set-Cookie ******************

响应正文是:

var li = '<li>';
li += '<img alt="Paperclip" src="/images/paperclip.png?1323904510" /> ';
li += '<a href="/XXXXX/183400184/download_attachment/980191034">test.txt</a> <img alt="Cross_16x16" data_url="/XXXXX/183400184/destroy_attachment/980191034" src="/images/cross_16x16.png?1327452770" />';
li += '</li>';
$('ul#attachments').append(li);

在 Chrome、Firefox 等上...都很好。

在 IE 上，它询问我是否要打开或保存 update_attachment.js ？？？

其他ajax调用工作正常，它正确解释javascript响应，仅使用fileupload no....

编辑:

IE 未传入请求 header :

  X-Requested-With  XMLHttpRequest

Answer 1

我认为这回答了我的问题

forceIframeTransport

Set this option to true to force iframe transport uploads, even if the browser is capable of XHR file uploads. This can be useful for cross-site file uploads, if the Access-Control-Allow-Origin header cannot be set for the server-side upload handler which is required for cross-site XHR file uploads.

Type: boolean
Default: false

IE 没有执行 XHR 请求...
