Uncaught TypeError: Cannot read property 'addEventListener' of null

<script type="text/javascript">
		
		var body1=document.getElementById('#body')
                </script>

　

 

錯誤提示：
Uncaught TypeError: Cannot read property 'addEventListener' of null

 

修改代碼如下：

<script type="text/javascript">
		
		var body1=document.getElementById('body')
                </script>

 

成功
