用的时候把runcode.js放到网站目录，在需要运行代码的效果的地方放如下的代码
复制代码 代码如下:
<divstyle="margin-top:1em;margin-bottom:1em"><divstyle="display:none">{1}</div><textarearows="12"cols="95"style='font-family:"CourierNew",Courier,monospace;'></textarea><scriptsrc="runcode.js"></script><br/><inputtype="button"value="运行代码"style="border-left:1pxsolid#B1B4CD;border-right:1pxsolid#494D74;border-top:1pxsolid#B1B4CD;;border-bottom:1pxsolid#494D74;background:#696D81;color:#FFFFFF;"onclick="runCode(this)"><inputtype="button"style="border-left:1pxsolid#B1B4CD;border-right:1pxsolid#494D74;border-top:1pxsolid#B1B4CD;;border-bottom:1pxsolid#494D74;background:#696D81;color:#FFFFFF;"value="复制代码"onclick="copycode(this)"><inputtype="button"style="border-left:1pxsolid#B1B4CD;border-right:1pxsolid#494D74;border-top:1pxsolid#B1B4CD;;border-bottom:1pxsolid#494D74;background:#696D81;color:#FFFFFF;"value="另存代码"onclick="saveCode(this)"><inputtype="button"style="border-left:1pxsolid#B1B4CD;border-right:1pxsolid#494D74;border-top:1pxsolid#B1B4CD;;border-bottom:1pxsolid#494D74;background:#696D81;color:#FFFFFF;"value="还原代码"onclick="preCode(this)">提示：您可以先修改部分代码再运行</div>
就可以了。
