Ajaxform upload file directly prompts for download compatibility bug under IE

When uploading a file using Ajaxform, directly prompt for download and save under IE:

My sample code:

   return this. Json (            new                {                    Prop1 = 5,                    prop2 = Ten                });

This problem only appears under IE, because Ajaxfrom only accepts JSON returned in HTML format, so you need to set content in the returned JSON object:

   return  This . Json (            new                {                    5,                    ten                },              "text/html");
