使用ts定義，可限制引數的型別

新建ts檔案

// 定義介面限制物件屬性
export interface personInter {
    name:string,
    age:number,
    gender:string
}

// 使用泛型
// export type personArr = Array<personInter>
// 另一種寫法
export type personArr = personInter[]

引入並使用

<template>
    <div class="person">
        ???
    </div>
</template>

<script lang="ts" setup name="Person">
    import {type personInter,type personArr} from '@/types'
    let person1:personInter = {name:'111',age:20,gender:'F'}
    let person2:Array<personInter> = [
        {name:'111',age:20,gender:'F'},
        {name:'222',age:20,gender:'F'},
        {name:'333',age:20,gender:'F'}
    ]
    let person3:personArr = [
        {name:'111',age:20,gender:'F'},
        {name:'222',age:20,gender:'F'},
        {name:'333',age:20,gender:'F'}
    ]
</script>

<style scoped>
    .person {
        background-color: skyblue;
        box-shadow: 0 0 10px;
        border-radius: 10px;
        padding: 20px;
    }
    
    button {
        margin : 0 5px;
    }

    li {
        font-size : 20px;
    }
</style>
