Conclusion
就像在先前练习中见过的，我们可以通过使用on<name>形式的函数监听Dom元素的事件（例如：单击事件，指针移动事件）
As we’ve briefly seen already, you can listen to any DOM event on an element (such as click or pointermove) with an
on<name>function:
App
<div onpointermove={onpointermove}>
The pointer is at {Math.round(m.x)} x {Math.round(m.y)}
</div>跟其它属性一样，如果属性和值名称一样我们就可以使用简写形式:
Like with any other property where the name matches the value, we can use the short form:
App
<div {onpointermove}>
The pointer is at {Math.round(m.x)} x {Math.round(m.y)}
</div>1

<script>
let m = $state({ x: 0, y: 0 }); function onpointermove(event) {m.x = event.clientX;
m.y = event.clientY;
}
</script>
<div>
The pointer is at {Math.round(m.x)} x {Math.round(m.y)}</div>
<style>
div {position: fixed;
left: 0;
top: 0;
width: 100%;
height: 100%;
padding: 1rem;
}
