就是共享的状态用state来存放，用mutations来操作state，但是需要用store.commit来主动式的操作mutations。
export default { [VIEW_NAV]: ({ commit, state }, payload) => { commit('VIWE_NAV', payload) }, [VIEW_FOOT]: ({ commit, state }, payload) => { commit('VIWE_FOOT', payload) }, [VIEW_LOADING]: ({ commit, state }, payload) => { commit('VIEW_LOADING', payload) }, [UPD...
Vuex 的思想是 当我们在页面上点击一个按钮，它会处发(dispatch)一个action, action 随后会执行(commit...
context.commit('increment') } } }) 1、流程顺序 “相应视图—>修改State”拆分成两部分,视图触发Action,Action再触发Mutation。 2、角色定位 基于流程顺序,二者扮演不同的角色。 Mutation:专注于修改State,理论上是修改State的唯一途径。 Action:业务代码、异步请求。 3、限制 角色不同,二者有不同的限制。 Mutat...

测试失败,理所当然。报错信息为TypeError: store.commit is not a function。让我们来实现commit方法,同时也要把options.mutations赋值给this.mutations,这样才能在commit中访问到: classStore{constructor(options) {this.state=reactive(options.state)this.mutations=options.mutations}commit(handle,payload) {constmutatio...
