IE,FireFox 差异如下:
IE6.0、FF1.06+:
clientWidth = width + padding
clientHeight = height + padding
offsetWidth = width + padding + border
offsetHeight = height + padding + border
IE5.0/5.5:
clientWidth = width - border
clientHeight = height - border
offsetWidth = width
offsetHeight = height
<script type="text/javascript">
<!-- var winWidth = 0;
var winHeight = 0;
function findDimensions() //函数:获取尺寸
{ //获取窗口宽度
if (window.innerWidth)
winWidth = window.innerWidth;
else if ((document.body) && (document.body.clientWidth))
winWidth = document.body.clientWidth; //获取窗口高度
if (window.innerHeight)
winHeight = window.innerHeight;
else if ((document.body) && (document.body.clientHeight))
winHeight = document.body.clientHeight; //通过深入Document内部对body进行检测,获取窗口大小
if (document.documentElement && document.documentElement.clientHeight && document.documentElement.clientWidth)
{
winHeight = document.documentElement.clientHeight;
winWidth = document.documentElement.clientWidth;
} //结果输出至两个文本框
document.form1.availHeight.value= winHeight;
document.form1.availWidth.value= winWidth;
} findDimensions(); //调用函数,获取数值
window.onresize=findDimensions;
//--> </script>
