js\css 让图片垂直居中
资料:用JAVASCRIPT获取当前窗口的高度和宽度
<SCRIPT LANGUAGE="JavaScript">
var s = "";s += "网页可见区域宽：" + document.body.clientWidth;s += "<br>网页可见区域高："+ document.body.clientHeight;s += "<br>网页可见区域宽："+ document.body.offsetWidth +" (包括边线和滚动条)";s += "<br>网页可见区域高："+ document.body.offsetHeight +" (包括边线)";s += "<br>网页正文全文宽："+ document.body.scrollWidth;s += "<br>网页正文部分上："+ window.screenTop;s += "<br>网页正文部分左："+ window.screenLeft;s += "<br>屏幕分辨率的高："+ window.screen.height;s += "<br>屏幕分辨率的宽："+ window.screen.width;s += "<br>屏幕可用工作区高度："+ window.screen.availHeight;s += "<br>屏幕可用工作区宽度："+ window.screen.availWidth;s += "<br>你的屏幕设置是 "+ window.screen.colorDepth +" 位彩色";s += "<br>你的屏幕设置 "+ window.screen.deviceXDPI +" 像素/英寸";
document.write(s);
</script>代码:
<html><body onresize="myLoad()" onload="myLoad()"><div id="xuanma" style="Z-INDEX: 1; LEFT: 0px; POSITION: absolute; TOP: 0px"><img id="ximage" src="yah/GroupImages/060823nhp1.jpg"/></div><SCRIPT language="javascript" type=text/javascript>function myLoad()
{
document.getElementById('xuanma').style.top= document.body.clientHeight/2-document.getElementById('ximage').height/2;document.getElementById('xuanma').style.left= document.body.clientWidth/2-document.getElementById('ximage').width/2;
}</SCRIPT></body></html>
