How to obtain the returned value in Chinese garbled characters asynchronously using JQuery _ jquery-js tutorial

This article mainly introduces how to obtain Chinese garbled characters in return values asynchronously by JQuery.

I also suspected that the jqGrid tool function was missing the contentType: "application/x-www-form-urlencoded; charset = UTF-8 ", and so on.

@ RequestMapping (value = "/searchUserList. form ") @ ResponseBody public void searchUserList (int page, int rows, HttpServletRequest request, HttpServletResponse response) throws IOException {System. out. println ("idcard =" + idCard + "\ n page =" + page + "\ n rows =" + rows); List
 
  
List = userService. findByIDCard (idCard); int totalRecord = list. size (); int totalPage = totalRecord % rows = 0? TotalRecord/rows: (totalRecord/rows + 1); int index = (page-1) * rows; int pageSize = rows; String json = "{\" total \": \ "" + totalPage + "\", \ "page \": \ "" + page + "\", \ "records \": \ "" + totalRecord + "\", \ "rows \": ["; for (int I = index; I <pageSize + index & I
