是否可以将Vue.js组件作为实例获取？

<template>
  <div>
    <my-component ref="myComponent"></my-component>
  </div>
</template>

<script>
import MyComponent from './MyComponent.vue';

export default {
  components: {
    MyComponent
  },
  mounted() {
    const myComponentInstance = this.$refs.myComponent;
    // 可以通过myComponentInstance访问组件的属性和方法
  }
}
</script>

<template>
  <div>
    <my-component></my-component>
  </div>
</template>

<script>
import MyComponent from './MyComponent.vue';

export default {
  components: {
    MyComponent
  },
  mounted() {
    const myComponentInstance = this.$children.find(child => child instanceof MyComponent);
    // 可以通过myComponentInstance访问组件的属性和方法
  }
}
</script>
