在canvas监听鼠标右键，如何屏蔽默认的菜单？

Question

我下面的写法不知道为什么一点用也没有

<canvas id="myCanvas" 
        style="background-color: yellow;" 
        width="400" 
        height="400">
</canvas>

<script>
const el=document.getElementById('myCanvas')

const onRightClick=(e)=>{
    e.stopPropagation()
    e.preventDefault() 
    return false;
}

el.addEventListener('oncontextmenu',onRightClick)
</script>

Answer 1

el.addEventListener('contextmenu',onRightClick)

或者

el.oncontextmenu = onRightClick
