    offsetWidth 和 scrollLeft 的应用 和子容器800%与父容器的使用

    参考 http://blog.csdn.net/xuantian868/article/details/3116442

    obj.offsetWidth 指 obj 控件自身的绝对宽度,不包括因 overflow 而未显示的部分,也就是其实际占据的宽度,整型,单位像素。

    3.scrollLeft,scrollTop:
    如果元素是可以滚动的,可以通过这俩个属性得到元素在水平和垂直方向上滚动了多远,单位是象素.
    对于不可以滚动的元素,这些值总是0.

    scrollLeft 主要用来定位子容器在父容器中的定位,控制子容器的位置
