前端学习-vue视频学习008-TS中的接口\泛型\自定义类型

尚硅谷视频链接

使用ts定义，可限制参数的类型

新建ts文件

// 定义接口限制对象属性
export interface personInter {
    name:string,
    age:number,
    gender:string
}

// 使用泛型
// export type personArr = Array<personInter>
// 另一种写法
export type personArr = personInter[]

引入并使用

<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>
