标准、非标准，多游览器，client、offset、scroll等函数所有解析。
clientTop,clientLeft
clientWidth,clientHeight
offsetTop,offsetLeft
offsetWidth,offsetHeight
scrollTop,scrollLeft
scrollWidth,scrollHeight
自写JS类，需要考虑标准和非标准下使用的用户，又得考虑多游览器。
所以做了这个研究，DIV，HTML，BODY的结果都不相同，非常让人郁闷，
发出来做共巷研究。
所以结果发出。
HTML、BODY。测试。
窗体大小800*300
（表担心，我是用PS去测量的大小。）
Html css: margin:21px 22px 23px 24px;
Body css: margin:11px 12px 13px 14px;
有滚动状态时，将在BODY中增加Div为，大小800*300
Div。测试。
大小800*600，包括滚动条在内。
有滚动状态，DIV内增加DIV850*300
标准 显示滚动条 无滚动状态.
