------------------------servlet
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Employee employee_01 = new Employee(); employee_01.setUid("1"); employee_01.setUsername("张三"); Employee employee_02 = new Employee(); employee_02.setUid("2"); employee_02.setUsername("李四"); List<Employee> list = new ArrayList<Employee>(); list.add(employee_01); list.add(employee_02); request.setAttribute("list", list); request.getRequestDispatcher("/list.jsp").forward(request, response);
问题补充:
你是指,在从servlet 跳转至该页面后,点击下拉菜单,选择一个值的时候,不会触发这下面这个:
引用
# function(){ # # $("#sel_emp").live('change',function(){ # var value = $('#sel_emp').val(); # alert(value); # window.location = "/aa/servlet/Test1Servlet"; # }
是么?
是的
