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...

ReferenceError:VUE_PROD_DEVTOOLSis not defined at Store.install (E:\vuex-reproduce\node_modules\vuex\dist\vuex.cjs.js:911:50) I met this issue too. My current solution is changing Vuex dependency version from"vuex": "^4.0.1"to"vuex": "4.0.0". ...
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...
commit (type, payload) { let entry = this._mutations[type] if (!entry) { return new Error(`${type} is not defined`) } entry(this.state, payload) } dispatch (type, payload) { let entry = this._actions[type] if (!entry) { ...
user.token = token } }, actions: { updateUserToken({ commit }, token) { commit('setUserToken', token) } }, plugins: [createPersistedState()] }) 在这个示例中,我们在 Vuex store 的配置中直接引入了 vuex-persistedstate 插件,并将 user.token 状态持久化。
and since vuex doesn't currently provide any kind of notification when replaceState() has been called, starting with v2.1.0 vuex-persist will add a restored property to the store object to let you know the state has been restored and that it is now safe to commit any mutations that modify...
