useOnceWatch

useOnceWatch 跟watch类似，只触发一次监听，然后自动停止监听

基础用法

<template>
  <div>Hello World! {{ count }}</div>
  <button @click="count++">Add</button>
</template>

<script setup lang="ts">
import { ref } from "vue";
import { useOnceWatch } from "hooks-vue3";
const count = ref<number>(0);
useOnceWatch(count, () => {
  console.log("只进来一次，然后自动停止监听");
});
</script>

API

useOnceWatch(count,callback,options);

参数TS类型

import type { WatchCallback, WatchOptions, WatchSource } from 'vue';

function useOnceWatch<T = any, Immediate extends Readonly<boolean> = false>(
  source: T | WatchSource<T>,
  cb: WatchCallback<T>,
  options?: WatchOptions<Immediate>,
)
