Conclusion
前面已经介绍过<svelte:window>和<svelte:document>了，类似得还有<svelte:body>, 像先前提到的尽量用它绑定mouseenter和mouseleave事件处理函数:
Similar to
<svelte:window>and<svelte:document>, the<svelte:body>element allows you to listen for events that fire ondocument.body. This is useful with themouseenterandmouseleaveevents, which don’t fire onwindow. Addonmouseenterandonmouseleavehandlers to the<svelte:body>tag...
App
<svelte:body
onmouseenter={() => hereKitty = true}
onmouseleave={() => hereKitty = false}
/>小主人可以划拉下鼠标看下效果了。
...and hover over the
<body>.
