googleada.js

程序中带有大量的实例,采用多种方式优化代码,这初学者很好的学习资料

function initAd() {
//cxssdiv为google广告层
//online为在线咨询层
cxssdiv.style.visibility = 'visible' //设置层为可见
cxssdiv.style.posTop = -100; //设置onLoad事件激发以后，广告层相对于固定后的y方向位置
//------------------在线咨询--------------------------------------
online.style.visibility = 'visible'
online.style.posTop = -100;

MoveLayer(); //调用函数MoveLayer()
}
function MoveLayer() {
var x = 2 //浮动广告层固定于浏览器的x方向位置
var y = 200; //浮动广告层固定于浏览器的y方向位置
var diff = (document.documentElement.scrollTop + y - cxssdiv.style.posTop)*.40;
var y = document.documentElement.scrollTop + y - diff;
cxssdiv.style.posTop = y;
cxssdiv.style.posLeft = x; //移动广告层
//-------------------------在线咨询---------------------------------
var ox = 880
online.style.posTop =y;
online.style.posLeft = ox; //移动广告层

setTimeout("javascript:MoveLayer()", 20); //设置20毫秒后再调用函数MoveLayer()
}
