浅谈javascript属性onresize

//获取屏幕宽度并动态赋值  
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

$("body").height(winHeight)
$("body").width(winWidth)
}

findDimensions();
//调用函数，获取数值
window.onresize=findDimensions;
