火狐浏览器，360浏览器servlet竟然跳转到空白页面，忙活一天了

Question

//jsp的代码：

 function updatedata(){
    $('#updateDeptInfo').form('submit', {
            url:'update_DEPT_INFO',
            success:function(){
              //if(data){
              alert('修改成功');
              $('#updatedlg').dialog('close');
              $('#dg').datagrid('reload');
              //}     
            }
        });
}


//后台servlet代码
public class update_DEPT_INFO extends HttpServlet{
    private static final long serialVersionUID = 1L;

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        System.out.println("执行修改部门一次");
        response.setContentType("text/html;charset=utf-8");
        request.setCharacterEncoding("utf-8");
        String did = request.getParameter("did");
        String uposition = request.getParameter("uposition");
        DEPT_INFO_Service service = new DEPT_INFO_Service();
        service.update_DEPT_INFO(did,uposition);
        //PrintWriter out = response.getWriter();
        //out.println(true);
    }

}
