今天查看了下新浪的js代码,发现一个背投的广告类代码,不论是从学习角度还是使用角度都是不错的,但发现了一个问题,会被屏蔽的。
下面是具体的js类代码
复制代码 代码如下:
/*
轮播背投类 RotatorPB v3.1
Update by Dakular <shuhu@staff.sina.com.cn> 2008-8-25
格式:new RotatorPB(广告数组)
说明:第一次访问随机出现,以后访问顺序轮播;自动过滤过期广告;cookie时间24小时;商业广告数量不足时不显示
*/

具体的调用代码:
复制代码 代码如下:
<script src="/UploadFiles/2021-04-02/rotator_pb.js"><SCRIPT language=javascript type=text/javascript>
//<![CDATA[
var rpb = new Array();
rpb.num = 2; //轮播数量
<!--2220E7B88D58-->//背投广告创意

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
