如何仅针对iframe显示垂直滚动条？

Question

以下html代码不显示垂直滚动条。为什么？

 <style>
        #mapIframe{
            min-height:300px;
            overflow:auto !important;
            direction:rtl  !important;
            overflow-x:hidden   !important;
            overflow-y:scroll   !important;
            height:100%; //optional, but it can't hurt.
        }
    </style>




<iframe id="mapIframe" src="aurl" width="300" height="800" frameBorder="0">Browser not compatible.</iframe>

删除scrolling="no"或将其更改为yes。
