javascript 面向对象编程 function是方法(函数) jQuery slider Content(左右控制移动)

基于innerHTML中的script广告实现代码 ,主要是为了统一管理广告，但因为innerHtml的script的一些问题不建议script的代码下面是一些测试。

如果不清楚innerHtml的脚本如何运行的可以参考这篇文章
http://www.ruanchen.com/"codetitle">复制代码代码如下:

if(PageClass==2) 
{ 
 //顶部通栏 468*60用iframe方式加载 
 set_innerHTML('Head_2_2',All_Top_468_60); 
 //顶部468*60 
 set_innerHTML('Head_5',All_Top_970_60); 
 Temp_Adv='<iframe scrolling="no" frameborder="0" marginheight="0" marginwidth="0" width="240" height="152" 
src="/show/html/List_1_1_4.html" style="margin-bottom:5px;"></iframe>'; 
 set_innerHTML('List_1_1_4',Temp_Adv); 
//下载右边文字 直接地址+图片 推荐 
Temp_Adv='| <a href="http://www.ruanchen.com?" class="wLink" target="_blank">软晨学习网</a> '; 
 document.getElementById("Soft_1_2_4_h2").innerHTML+=Temp_Adv; 
 // set_innerHTML('Soft_1_2_2_1_2',Temp_Adv); 
}

点击运行可以看到效果:

<div id="jb51"></div>
<div>
<div id="ss">上面的是4668*60</div>
</div>
<div id="jb512"></div>
上面的是4668*602 因为直接用的是inner所有不显示。

[Ctrl+A 全选提示:你可先修改部分代码,再按运行]

经测试发现，如果想在有运行script的上面加广告是不可能的因为这些脚本是后执行的，所有脚本广告可以直接在脚本中写入，不要随便的后加入了。
但如果是其它的广告是可以前面加入广告的，一些网站都是直接通过script控制全站的广告，虽然软晨学习网暂时没有使用这种方法，不过在以后我们也会参考这个方法。
最主要的是广告，大家可以尽量的避免使用script,尽量的使用iframe或直接代码，图片链接等方法是非常不错的。
