关于省市级联的问题

我现在写好一个JS是省市级联的那种，我现在有一个模板，有一个页面套用这个模板，但是JS没有效果
但是如果我加入一个没有调用模板的页面这个功能就能实现，因为需要在Body中调用OnLoad事件！
但是我只有在模板中才有Body，应用页没有Body！
我该怎么办？ --------------------编程问答-------------------- 求高手帮助啊！ --------------------编程问答-------------------- 对象不对了。 --------------------编程问答--------------------

--------------------编程问答-------------------- 楼主是用的masterpage吧，可以是用添加属性的方法实现。或者在一个div里加onload也成啊 --------------------编程问答-------------------- 在页面的window.onload事件里面试试.
或者js 的  OnLoad() 事件里写 --------------------编程问答-------------------- 一张单独的页，或用自定义控件。放省市级联控件。

然后页面引用，或者iframe引用这个页。

两种方法。

--------------------编程问答-------------------- 在该页面的后台程序使用注册脚本引入你这个级联JS就行

--------------------编程问答-------------------- 还有没有什么办法了？

这是JS代码,以安徽为例 --------------------编程问答--------------------

for(i=0;i <v;i++){ str+=("_"+(document.getElementById(s[i]).selectedIndex-1));};

想当然地去使用s[i]，这类代码我懒的分析，它的思路就是一种“绞架”模式——你越用它越快陷入泥潭。
