### 重现步骤

给输入框先输入几个空格，然后搜索北京，结果正常显示，然后删除北京，保留空格，快速滑动elevator组件，就会出现，Cannot read properties of undefined (reading 'num')，num就是自定义索义key，对应代码 class: B(["nut-elevator__bars__inner__item", { active: i[e.acceptKey] === e.indexList[e.currentIndex][e.acceptKey] }]),

### 期望的结果是什么？

正常显示

### 实际的结果是什么？

页面报错，清空输入框以后，原来数据也没有，必须刷新页面才可以
