避免直接改变prop,因为当父组件重新呈现时,该值将被覆盖。 相反,使用基于道具值的

ps:
避免直接改变属性，因为当父组件重新呈现时，该值将被覆盖。相反，使用基于属性值的数据或计算属性。道具正在变异：“tabIndex

Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop’s value. Prop being mutated: “tabIndex”

这样的时候，需要再子页面的data里面去创建一个值去接受父页面传递过来的值，这样这个警告就会消失掉
父组件传递过来的tabIndex，在子组件的时候，用props接受了之后，然后在data里面创建一个变量去接受，这样就能去掉这个警告了

子组件获取值是bIsOpenState
定义一个bIsOpenState1来接受这个值
视图绑定用bIsOpenState1
