    this.$().on('mouseleave', this.handleMouseLeave.bind(this));
  },

  willDestroyElement() {
    this._super(...arguments);

    // 在组件销毁前解绑事件
    this.$().off('mouseenter', this.handleMouseEnter.bind(this));
    this.$().off('mouseleave', this.handleMouseLeave.bind(this));
  },

  handleMouseEnter() {

    console.log('Mouse entered');
  },

  handleMouseLeave() {
    // 处理鼠标离开事件
