clientWidth:元素内容区的宽度加上左右padding的值,如果有滚动条,不包括滚动条的宽度

clientHieght: 元素内容区的高度加上上下padding的值,如果有滚动条,不包括滚动条的高度

clientLeft:元素左边框的宽度,如果没有边框,就是0

clientTop:元素上边框的宽度,如果没有边框,就是0

 

scrollWidth:元素的滚动宽度,不包括元素边框和滚动条宽度,即元素边框和滚动条之间的宽度加上延伸到元素外面的部分

scrollHeight:元素的滚动高度,不包括元素的边框盒滚动条宽度,即即元素边框和滚动条之间的高度加上延伸到元素外面的部分

scrollLeft:元素水平滚动的距离

scrollTop: 元素垂直滚动的距离

 

offsetWidth:元素从左边框到右边框的宽度

offsetHeight: 元素从上边框到下边框的高度

offsetLeft:元素到offsetParent的偏移量

offsetTop: 元素到offsetParent的偏移量

(关于offsetParent offsetLeft offsetTop请参阅《元素的offsetParent offsetLeft offsetTop属性》)

另外,FF中的window属性innerWidth innerHeight只的是显示文档的整个视窗的宽度和高度(即浏览器中除了工具栏,菜单栏,地址栏以外的部分),而outerWidth outerHeight指的是整个浏览器窗口的宽度和高度,即文档视窗高度和宽度 + 工具栏,地址栏,菜单栏这些部分

以上的结论是通过下面测试代码得出:
