jQuery ajax issue on IE9
ajax, asp.net-mvc, internet-explorer-9, jquery
Solution
Try
return Json(new { Data = new { message = outputFilePathResponse } }, "text/html");
Reference: IE tries to download JSON in ASP. NET MVC 3
Problem
I am using this plugin to let users upload images trough ajax. To create the uploader and trigger a post this jQuery function is used: ``` function createUploader() { var uploader = new qq.FileUploader({ element: document.getElementById('file-uploader'), allowedExtensions: ['pdf'], multiple: false, action: '@Url.Action("AjaxUpload", "Upload")', onComplete: function(id, fileName, responseJSON){ window.location.href = responseJSON.message; } }); } ``` Well, in `responseJSON.message` I am returning the path where the file was uploaded (actually converted) and I am doing a trick with `window.location.href` to force the browser to show the user DOWNLOAD box for that file. This works great on FF and Chrome but on IE it says: `Do you want to open or save AjaxUpload from localhost?` And if you press open, instead of getting the file from the specified location, you actually get a file containing responseJSON message. Any jQuery guru who can give me a clue for this issue? UPDATE: What I can confirm is that the issue is not with `window.location.href = responseJSON.message;` because even if I remove this line and put `alert('something')` the same problems occurs...so instead of parsing `onComplete`, IE try to open the JSON response...
