如何在Ionic-vue应用程序中setFocus下一个按钮按下事件？

<ion-button ref="button1" @click="handleButtonClick">按钮1</ion-button>
<ion-button ref="button2" @click="handleButtonClick">按钮2</ion-button>

methods: {
  handleButtonClick() {
    // 获取当前按钮的ref
    const currentButtonRef = this.$refs.button1; // 假设当前点击的是按钮1

    // 获取下一个按钮的ref
    const nextButtonRef = this.$refs.button2;

    // 设置焦点到下一个按钮
    nextButtonRef.focus();
  }
}
