jQuery Upload File

因為要用 web api 做檔案上傳，找了幾篇教學：

jQuery Ajax File Upload

發現要直接用jQuery post上傳檔案，它的data是個FormData物件，然而IE在10之後才有支援此功能。。。

IE9 JSON Data “do you want to open or save this file”
如果用ajaxForm()呼叫WebApi要回傳json，但IE會一直跳出下載，要多加一段

var response = Request.CreateResponse(HttpStatusCode.OK, json); //, new JsonMediaTypeFormatter()
response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("text/html");
return response;
