FLEX给页面添加滚动条实现思路及代码

复制代码 代码如下:

var winWidth = 0;
var winHeight = 0;
function findDimensions()
{
//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;
}

var cssSize = document.styleSheets[0].rules||document.styleSheets[0].cssRules;
if(winWidth < 1100)
{
cssSize[0].style.width = "1100px";
}
else
{
cssSize[0].style.width = "100%";
}

if(winHeight < 600)
{
cssSize[0].style.height = "600px";
}
else
{
cssSize[0].style.height = "100%";
}
}

window.onresize=findDimensions;

function pageInit() {
//调用函数，获取数值
findDimensions();

}
