var str = "left=0,screenX=0,top=0,screenY=0,fullscreen=yes";//fullscreen=yes只对IE有效！

str += ",height=" + ah;
str += ",innerHeight=" + ah;
str += ",width=" + aw;
str += ",innerWidth=" + aw;
} else {
str += ",resizable"; // 对于不支持screen属性的浏览器，可以手工进行最大化。 manually
}

function launchFull(url, name) {
return window.open(url, name, str);
}

var win = launchFull("http://www.jiangdu.net", "full");
