js改变div高度

用bootsrap响应式布局的时候，遇到个很恶心的问题：左边栏很短很难看！！

于是，想用js来自动改变左边的高度，没成功！！原来是设置的时候，没加单位，坑爹了。

参考：http://blog.sina.com.cn/s/blog_3d8c704c0101145y.html

设置高度的时候，加上px

<script>
        function load(){
            var height = window.innerHeight;
            document.getElementById("sidebarOuter").style.minHeight = height+"px";
            document.getElementById("if").style.minHeight = height+"px";
        }
</script>

然后整个左边栏，就和浏览器高度一致了：

完整源码如下，备忘：
