2、计算属性getters 1)选项式:即可以在参数中传入state,也可以直接在方法体中调用this,如【getters: { squareCount(state){return state.count*state.count;} }】,等价于【getters: { squareCount(){return this.count*this.count;} }】 2)函数式:和在setup中写计算属性一样,const squareCount = computed( ...

pinia 官方简介 说明 pinia 由 store state getters actions 组成 在组件中通过获取 store 的 sate 来获取状态和修改状态 通过 gtters 可以对数据进行复杂的计算并进行应用，例如实现过滤和排序等 也可以通过 actions 复用更复杂的修改逻辑，进行几步的状态修改 与 Vuex 不同的是 pinia 里面没有 mutations 的概念，...
