vue3中的任何一个组合式api都可以单独抽离出去在另一个文件，最后只需要回归到setup()中即可。
// 公共的数据和方法
import { reactive } from "vue"
const publicModule = ()=>{
const res = reactive({
name:"马腾腾",
age:50,
company:"百度"
})
return res
}
export default publicModule注意const res = publicModule()这里的值获取，容易写错获取不到；
点击handleClick事件修改引入的值
<template>
<div>
<div class="main">
<div>vue3抽离封装:</div>
<div>name:{{res.name}}</div>
<div>age:{{res.age}}</div>
<div>company:{{res.company}}</div>
<el-button type="primary" block @click="handleClick">修改name</el-button>
</div>
</div>
</template>
<script>
import publicModule from "../../utils/publicModule"
export default {
setup() {
const res = publicModule();
console.log(res,"vue3抽离封装");
function handleClick(){
res.name = "马云"
}
return {
res,
handleClick
};
}
};
</script>
或者使用toRefs
<template>
<div>
<div class="main">
<div>vue3抽离封装:</div>
<!-- toRefs -->
<div>name:{{name}}</div>
<div>age:{{age}}</div>
<div>company:{{company}}</div>
<el-button type="primary" block @click="handleClick">修改name</el-button>
</div>
</div>
</template>
<script>
import publicModule from "../../utils/publicModule"
import {toRefs} from "vue"
export default {
setup() {
const res = publicModule();
console.log(res,"vue3抽离封装");
function handleClick(){
res.name = "马云"
}
return {
...toRefs(res),
handleClick
};
}
};
</script>
