This article introduces the knowledge of "what is the way to call vuex mutation action at the same level". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Mutation action sibling call

Mutatiion sibling call: this.commit

Action sibling call: this.dispatch

/ synchronous const mutations = {add (state, payload) {state.countB + = 10}, plus (state, payload) {this.commit ('add')}} / / Asynchronous (timer, etc.) const actions = {addCountBAction ({state, commit}, payload) {commit (' add', payload)}, plusCountBToAAction ({state, commit, dispatch, getters, rootState, rootGetters} Payload) {/ / https://vuex.vuejs.org/zh/api/#actions setTimeout (() = > {dispatch ('addCountBAction')}, 2000) / / or thiis.dispatch ('addCountBAction')}} mutation and action distinguish const store = new Vuex.Store ({state: {count: 0}, mutations: {increment (state) {state.count++}}, actions: {increment (context) {context.commit (' increment')}}) 1, process order

"corresponding view-> modify State" is split into two parts, and the view triggers Action,Action and then triggers Mutation.

2. Role positioning

Based on the process order, the two play different roles.

Mutation: focusing on modifying State is theoretically the only way to modify State.

Action: business code, asynchronous request.

3. Restrictions

With different roles, the two have different restrictions.

Mutation: must be executed synchronously.

Action: you can do it asynchronously, but you cannot manipulate State directly.
