页面编码为GBK时 jquery 提交ajax数据完美解决中文乱码方案

例：Servlet中代码如下：

public class CategoryChangeServlet extends HttpServlet { public void service(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {request.setCharacterEncoding("utf-8");//由于ajax是以UTF-8传过来的，所以只要这里以UTF-8接受即可int id = Integer.parseInt(request.getParameter("id").toString());String fd = request.getParameter("fd");String val = request.getParameter("val");Category category = new Category();category.setCategoryName(val);if(id!=0 && fd!=null && val!=null){CategoryManager um = new CategoryManager();um.update(id,fd,category);}}}
