/*参数注释
slide_box：所在容器。slidebtn_align不为none时，必须设定slidebox
move_control：需要移动的元素
move：每次移动个数
move_way：移动方式，rool为滚动，fade为渐隐渐现
display：显示个数
offset：移动距离微调
speed：自动移动所需时间、无间歇移动间隔时间最好小于50
auto：是否自动运行
auto_interval：自动运行间隔时间
top：是否上下移动
auto2：是否无间歇的移动
direction：无间歇的移动的方向(参数：left、right、top、bottom)
priv_next：是否显示上下按钮
prev：上一个按钮
next：下一个按钮
prev_next_hover：上下按钮移上去样式
prev_next_hide：鼠标移到或移出容器后是否消失
prev_next_cycle：点击上下按钮是否循环移动
direction_cycle: 循环移动时是否一直是一个方向移动，mover必须为1
disabled：上下按钮禁用样式
slidebtn：是否显示数字控件
slidebtn_box：数字控件样式。当slidebtn_align不为none时，slidebtn_box的样式必须为position:absolute
slidebtn_html：是否自动填充控件内容
slidebtn_control：数字控件标签
slidebtn_num：数字控件是否显示数字
slidebtn_hover：数字控件选中样式
slidebtn_align：数字控件对齐方式。参数（none、left、right、center。none:不操作;left:左对齐(样式中可以直接控制左对齐，该处只控制容器宽度);center;居中;right:右对齐）
slidebtn_offset：数字控件间距。当slidebtn_align不为none时，改值可根据margin和padding的值设定*/
