name: THookName,
fn: RuntimeNuxtHooks[THookName] extends HookCallback ? RuntimeNuxtHooks[THookName] : never
): void
用法
¥Usage
参数
¥Parameters
name
:要注册的运行时钩子的名称。你可以查看 运行时 Nuxt 钩子 的完整列表。fn
:触发钩子时执行的回调函数。函数签名根据钩子名称而变化。
返回值
¥Returns
可组合项不返回值,但当组件的作用域被销毁时,它会自动注销钩子。
¥The composable doesn't return a value, but it automatically unregisters the hook when the component's scope is destroyed.
示例
¥Example
pages/index.vue
<script setup lang="ts">
// Register a hook that runs every time a link is prefetched, but which will be
// automatically cleaned up (and not called again) when the component is unmounted
useRuntimeHook('link:prefetch', (link) => {
console.log('Prefetching', link)
})
</script>
