vue3--学习技术胖笔记

<template>
  <div>
    <a href="https://vitejs.dev" target="_blank"></a>
    <H2>欢迎光临红浪漫洗浴中心</H2>
    <div>请选择一位美女</div>
    <button 
    v-for="(item,index) in girls" 
    v-bind:key="index"
    @click="selectGirlFun(index)"
    >
      {{index}}:{{item}}
    </button>
    <div>你选择了【{{selectGirl}}】为你服务</div>
  </div>
</template>

<script lang="ts">
import {defineComponent,ref} from "vue";

export default defineComponent({
  name:"APP",
  setup(){
    const girls =ref(["大脚","刘颖","小红"]);
    const selectGirl =ref("");
    const selectGirlFun = (index:number)=>{
      selectGirl.value=girls.value[index];
    }

    return{girls,
    selectGirlFun,
    selectGirl
  }}});
</script>

1、方法和值都写到了setup里面就可以了
