我的代码是
<div class="ws_bullets">
<a href="#" class="1 scrollup" >2</a>
<a href="#" class="2 scrollup" >3</a>
<a href="#" class="3 scrollup" >4</a>
<a href="#" class="4 scrollup" >5</a>
<a href="#" class="5 scrollup ">6</a>
<a href="#" class="6 scrollup ">7</a>
<a href="#" class="7 scrollup ">8</a>
<a href="#" class="8 scrollup ">9</a>
</div>
班级编号有背景图像集
scrollup just margin
ws_bullets是位置：固定;到右上角
我试图将div调整到窗口高度以扩展任何方式来执行此操作javascript？
