jQuery-File-Upload not firing done callback in Internet Explorer (IE9)
提问by Ricardo Braz?o
i checked some questions regarding the same issue, blueimp jquery file upload - "done", "complete" callbacks not working for IE 9, but even after putting my Content-Type as 'text/html' as the response the 'done' callback isn't being fired. Also as the jQuery-File-Upload says i need to have a redirect to get the uploaded file (https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads) after the upload is done, but that isn't also being done. Any help would be appreciated. Regards.
我检查了一些关于同一问题的问题，blueimp jquery 文件上传 - “完成”，“完成”回调不适用于 IE 9，但即使在将我的内容类型作为“文本/html”作为响应后，“完成”回调没有被解雇。同样，正如 jQuery-File-Upload 所说，我需要在上传完成后进行重定向才能获取上传的文件（https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads） ，但这还没有完成。任何帮助，将不胜感激。问候。

ok so i go it working.The problem was that in the fileuploader configuration i had
好的，所以我开始工作了。问题是在我的 fileuploader 配置中
dataType: 'json'
but since IE9 uses the iframe it makes a html request, and the response has the Content-Type 'text/html'. With that configuration the fileuploader is expecting to receive a json response so my response was going to a fail callback i made just for testing. Got it working by looking at this post jQuery FileUpload doesn't trigger 'done'
但由于 IE9 使用 iframe，它会发出一个 html 请求，并且响应的内容类型为“text/html”。使用该配置，fileuploader 期望收到一个 json 响应，因此我的响应将转到我仅为测试而制作的失败回调。通过查看这篇文章让它工作jQuery FileUpload 不会触发“完成”

The most voted answer isn't the best solution and can throw errors.Actually, setting dataTypeisn't recommended for IE < 10, from this (awesome) article:
投票最多的答案不是最佳解决方案，可能会引发错误。实际上，dataType不建议为 IE < 10 设置，来自这篇（很棒的）文章：
When the dataType option is set to text, json, html, or script, the iframe transport performs some processing of the response. Because it is operating on a DOM object obtained from the iframe it uses, however, and not the raw HTTP response data, there is the potential for some surprises to pop up.
当 dataType 选项设置为 text、json、html 或 script 时，iframe 传输会对响应执行一些处理。然而，因为它是在从它使用的 iframe 获得的 DOM 对象上操作的，而不是原始的 HTTP 响应数据，所以有可能会弹出一些惊喜。

Real solution:
真正的解决方案：
The "thing" about not firing in IE < 10 isn't related with dataType, is just the lack of callback addthat forces the file push in fileupload event.
在 IE < 10 中不触发的“事情”与 无关dataType，只是缺少add强制在 fileupload 事件中推送文件的回调。
$('#file_file').fileupload({
add: function (e, data) {
data.submit(); //this will 'force' the submit in IE < 10
},
done: function (e, data) {
alert('Done');
}
});
