如何调用组件prop - VueJS的方法？

<template>
  <div>
    <child-component :message="message"></child-component>
  </div>
</template>

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

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      message: 'Hello from parent component!'
    };
  }
};
</script>

<template>
  <div>
    <p>{{ message }}</p>
    <button @click="callParentMethod">Call Parent Method</button>
  </div>
</template>

<script>
export default {
  props: {
    message: String
  },
  methods: {
    callParentMethod() {
      // 在子组件中调用父组件的方法
      this.$emit('custom-event');
    }
  }
};
</script>

<template>
  <div>
    <child-component :message="message" @custom-event="handleCustomEvent"></child-component>
  </div>
</template>

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

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      message: 'Hello from parent component!'
    };
  },
  methods: {
    handleCustomEvent() {
      // 在父组件中处理子组件触发的自定义事件
      console.log('Custom event triggered in parent component!');
    }
  }
};
</script>
