你也可以内联声明事件处理程序：
App
<script>
let m = $state({ x: 0, y: 0 });
function onpointermove(event) {
m.x = event.clientX;
m.y = event.clientY;
}
</script>
<div
onpointermove={(event) => {
m.x = event.clientX;
m.y = event.clientY;
}}
>
The pointer is at {m.x} x {m.y}
</div><script lang="ts">
let m = $state({ x: 0, y: 0 });
function onpointermove(event) {
m.x = event.clientX;
m.y = event.clientY;
}
</script>
<div
onpointermove={(event) => {
m.x = event.clientX;
m.y = event.clientY;
}}
>
The pointer is at {m.x} x {m.y}
</div>1
