谁帮我改个JS翻页，下面的JN倒过来了````谢谢

      for (i=prev;i>=next;i--) //i=prev;i>=next;i--//i=1;i<=prev-next;i++
        { 
            if (i==Pageindex)
            { 
                html+="<font color=red>"+i+" </font>";
            }
            else
            { 
                html+="<a href='"+url+"page="+i+"'>"+i+"</a>"+" ";
            }
        }
i初始就是最后一页了！多调试下，应该能出来的！

    想加红色，没能加上，就是下面这段变一下
     for (i=prev;i>=next;i--) //i=prev;i>=next;i--//i=1;i<=prev-next;i++
            { 
                if (i==Pageindex)
                { 
                    html ="<font color=red>"+i+" </font>"+html;            }
                else
                { 
                    html ="<a href='"+url+"page="+i+"'>"+i+"</a>"+" " +html;            }
            }
            if(Pageindex!=1)
            {
                html ="<a href='"+url+"page="+(Pageindex-1)+"'>下一页</a>"+" " +html;
                html ="<a href='"+url+"page="+num+"'>末 页</a>"+" " +html;            }
