框架 HTML iframe

请问我做一网页
需要顶部div高度固定，宽度100%，下面放一个iframe框架
框架左侧div宽固定，高度100%，右侧宽高都是100%满屏显示，如屏幕小，右侧内容多的话则自动有滚动条，请问这要怎么做呢，在网上找了适应高度的都不行。

我随便测试的框架，右边的内容只显示一小部分，麻烦大虾们帮我看看，谢谢

回复讨论(解决方案)

div的自动撑满跟td不一样，不是左边250,右边100%就行的，需要自己计算一下div应有的宽度然后给相应的div设置。

你的1.html在load的时候判断一下浏览器的宽度，给content设置就行，简单的code如下，没有做详细的兼容性测试。

谢谢，是可以显示的，但是右边内容多的话，超出部分都会被隐藏掉也就是不显示，拉滚动条也不能到底，这不知道怎么解决，

2.html中把iframe的scrolling设成yes就应该可以了，里面的内容太多就会滚动了。

错了，是1.html中的iframe

还有一个建议，index.htm中的content的高度的100%继承的应该是body的高度，因此body的最终高度被撑到了document.body.clientHeight + 60，大于浏览器高度，因此不管右边frame里面的内容滚不滚，浏览器会一直有滚动条。

和上面的设置宽度的做法一样，可以改动index.htm页面，在load时content设一个高度。同时为了避免body的滚动条，再加上overflow:hidden。

可以参考下面的code，这样整个页面也整洁一些。
