. NET mvc4 + ajaxfileupload.js resolves the Internet Explorer Pop-up Download dialog box issue

Absrtact: Everyone encountered the problem is different, in the Internet to find a big circle has not solved my problem! Because my environment, as the title suggests, solves this problem.

Main problem: The setting of the response header

Controller:

        [HttpPost]        Public Contentresult uploadfile (string user = wintabconst.space, int type = Configconst.zero, string imgtype = Wintabconst . Space, int objId = Configconst.zero, DateTime? Createdatetime = null)        {            HttpPostedFileBase imgfile = request.files["Imgfile"];            ATTACHMENTBLL ATTACHMENTBLL;            if (!string. IsNullOrEmpty (user))                ATTACHMENTBLL = new ATTACHMENTBLL (user);            else                ATTACHMENTBLL = new Attachmentbll ();            int userId = 0;            Users usermodel = Attachmentbll.curuser;            if (user! = null)                userId = Usermodel.userid;            Return Content (JavascriptHelper.JsonSerializer.Serialize (Attachmentbll.uploadfile (True, "", Imgfile, type, Imgtype, ObjId, UserId, Createdatetime)));        }

Js:

$.ajaxfileupload (       {           URL: "/companies/attachment/uploadfile",           data: {"objId": ObjId, "Createdatetime": Createdatetime, "dir": "", "Type": "2", "userid": UserID, "User": $.cookie (' Logininfo ')},           type: "Post",           Secureuri:false,           dataType: "Text",           fileelementid: "Imgfile",           success:function (data) {               if (data! = Null && data = = "") {//This judgment is because the format for Json,ie received the data as "", but the picture is also a successful issue of                   $ (". Uploadimg"). Hide ();                   $ (". Mask"). Hide ();               } else if (data! = NULL && Data.error = = 0) {//My correct method of execution                   $ (". Uploadimg"). Hide ();                   $ (". Mask"). Hide ();               } else {                   Alertalert ("Upload failed! ");               }           ,           error:function (e) {               $.messager.alert (" Prompt "," Operation Error! ");           }       }   );
