hooks

当页面内有很多的功能，js代码太多，不好维护，可以每个功能都有写一个js或者ts，这样的话，代码易读，并且容易维护，组合式setup写法与此结合👍👍🏼👍👍👍👍

目录结构

demo

• useDogs.ts

import { ref, reactive  } from 'vue';
import axios from 'axios';
// https://dog.ceo/api/breed/pembroke/images/random
export default function () {let dogList = reactive(['https://images.dog.ceo/breeds/pembroke/n02113023_1816.jpg']);async function getDog() {try {let res = await axios.get('https://dog.ceo/api/breed/pembroke/images/random');dogList.push(res.data.message);console.log(res.data);} catch (error) {console.log(error);}}return {dogList,getDog}
}

• useSum.ts

import { ref, reactive } from 'vue';
import axios from 'axios';
export default function () {let sum = ref(0);function add() {sum.value += 1;}return {sum,add}
}

• 基本页面内容

<template><h2>当前求和为{{ sum }}</h2><button @click="add()">sum</button><button @click="getDog()">再来一只小狗</button><img v-for="dog in dogList" :src="dog" alt="" srcset="" /><br />
</template>
<script lang="ts" setup name="Hello321">
import useDogs from '@/hooks/useDogs';
import useSum from '@/hooks/useSum';
const { dogList, getDog } = useDogs();
const { sum, add } = useSum();
</script>
