setup,script里的，不知道怎么摆，先后顺序怎么样

<template>
  <div class="home">
    <p>父组件</p>
    <child @myevent="parentMethod"></child>
</div>
</template>

<script>
const child = {
      //触发myevent事件
      template: `<div @click="$emit('myevent')">子组件</div>`,
      emits:['myevent']
    }

export default {
  name: "Home",
  components:{
        child
      },
  setup() {
  emits: {
    click: null,
  }
      methods:{
        parentMethod(){
          console.log("父组件方法")
        }
      }
      
    }

</script>
