提示top.htm第34行有错，缺少对象。
还有，好心人请给出全代码可以吗？
假如我的Index.htm是这样的框架。（如下）____________________________
         Top.htm           |
___________________________|_
    |                |     |
    |                |     |
Left|     Main.htm   |Right|
    |                |     |
    |                |     |
----------------------------
         Buttom.htm        |
----------------------------我想在Top.htm上面做2个按钮，第一个ButtonA，实现onclick时可以隐藏或显示Left.htm；
第二个ButtonB，可以实现onclick时可以显示或隐藏Right.htm.但有一点要注意的是，Right.htm在默认的时候是不显示的。如何做呀？
框架名最好不要用"top"
假设你把你的name="top"换成了name="top1"
那么就是parent.document.top1.boy.cols="0,*";
用javascript改动col即可,当字符串附值
index.htm
