如何将modalView设置为false？

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      modalView: true
    };
  }

  closeModal() {
    this.setState({ modalView: false });
  }

  render() {
    return (
      <div>
        {this.state.modalView && <ModalView onClose={this.closeModal} />}
        {/* 其他组件内容 */}
      </div>
    );
  }
}

<template>
  <div>
    <modal-view v-if="modalView" @close="closeModal" />
    <!-- 其他组件内容 -->
  </div>
</template>

<script>
export default {
  data() {
    return {
      modalView: true
    };
  },
  methods: {
    closeModal() {
      this.modalView = false;
    }
  }
};
</script>

let modalView = true;

function closeModal() {
  modalView = false;
}
