成功最有效的方法就是向有经验的人学习!

漂浮广告,兼容ie、firefox,多个漂浮不冲突,调用只需两行代码

 将广告内容放在div中,设置一个id,然后用下面方法调用

var adcls=new AdMove("div的id");
 adcls.Run();

 

注意,在调用前要先引用Main.js和AdFloat.js,div也要在调用前写好,原因就不用说了吧

或者也可以用下面方法,在页面加载完成时调用,就不用考虑位置了

addEvent(window,"load",initad);
function initad(){
 var adcls=new AdMove("div的id");
 adcls.Run();
 }

 

还有两个方法一般情况下没什么用,有兴趣的可以试试,功能是设置漂浮的起始坐标和方向的,如果省掉的话是随机位置随机方向

 

adcls.SetLocation(x,y)
 adcls.SetDirection(dirx,diry)

 

漂浮广告的斜率是每次碰壁后随机改变的,这样就决不可能出现多个广告,起始位置和方向一致导致其中一个总是被挡住,虽然几率很小

第二版:

增加了关闭按钮,个人觉得按钮做得比较丑,不过还算实现了,我在ie7和firefox2.0.0.14最高版本做了测试

 

 调用增加了一个参数(可以省略),设为true就添加关闭按钮在右上角

 

var ad3=new AdMove("gg3",true);
 ad3.Run();
