Is a property expander, you can expand the method in mapMutations and put it in methods, and you can directly call methods: {. MapMutations (['method name in mutations'])}}-Why should you use mutations in the use of fine mutations?

The advantage of using mutations is that you can track where the method in mutations is called, and calling mutations in strict mode will not report an error.

Neither of the benefits mentioned above exists in any other way.

Usage

First define a mutations object, and then define the specified method, very simple, code example:

State: {isHome: true}, mutations: {changeIsHome (state) {/ / here state is passed in state.isHome = false}}

After defining the mutations method in stote.js, you can call the mutations method when the event is triggered in vue. Call the method example:

/ / the example here is to trigger the mutations method created () {this.$store.commit ('changeIsHome') / / this is the method called in the created method.

Execute: this.$store.commit ('changeIsHome'); and you can call the mutations method.
