After EasyUI form ajax submit to MVC, the system prompts the solution for downloading content in IE, easyuimvc

Problem description:

The project environment is. Net Mvc5 + EF6 ...... The front-end framework uses EasyUI v1.4.4. On the view page, when the form data is submitted using the form submit method, if IE is used, IE will prompt the download content after the request is successful, this is because the default Content-Type of IE is text/html, and the default Content-Type of Google browser we like to use is application/json. Solution:Based on the Problem description above, we can set the returned Content-Type to text/html before returning data. Solution code:We can customize a JsonResult method: 1 /// <summary> 2 /// custom JsonResult, 3 /// </summary> 4 /// <param name = "data"> data </param> 5 /// <param name = "behavior"> behavior </ param> 6 // <returns> JsonReuslt </returns> 7 protected JsonResult JsonSubmit (object data, jsonRequestBehavior behavior = JsonRequestBehavior. allowGet) 8 {9 return new JsonResultOverride10 {11 Data = data, 12 ContentType = "text/html", 13 // ContentEncoding = contentEncoding, 14 JsonRequestBehavior = behavior, 15 FormateStr = "yyyy-MM-dd HH: mm: ss" 16}; 17}View Code
