答案:
有五种,分别是 State、 Getter、Mutation 、Action、 Module
vuex的State特性 A、Vuex就是一个仓库,仓库里面放了很多对象。其中state就是数据源存放地,对应于一般Vue对象里面的data B、state里面存放的数据是响应式的,Vue组件从store中读取数据,若是store中的数据发生改变,依赖这个数据的组件也会发生更新 C、它通过mapState把全局的 state 和 getters 映射到当前组件的 computed 计算属性中 · vuex的Getter特性 A、getters 可以对State进行计算操作,它就是Store的计算属性 B、 虽然在组件内也可以做计算属性,但是getters 可以在多组件之间复用 C、 如果一个状态只在一个组件内使用,是可以不用getters · vuex的Mutation特性 Action 类似于 mutation,不同在于:Action 提交的是 mutation,而不是直接变更状态;Action 可以包含任意异步操作。
