. store.js:
state: {
value:''}
mutations: {
changeValue(state,newVal){
state.value=newVal
}}
.vue:
//
this.$store.commit('changeValue',1)
//
console.log(this.$store.state.value)//1
vuex, you can submit the value of store
official text:
the only way to change the state in the store of Vuex is to submit the mutation. Mutation in Vuex is very similar to events: each mutation has an event type (type) of a string and a callback function (handler). This callback function is where we actually make the state change, and it accepts state as the first parameter:
const store = new Vuex.Store({
state: {
count: 0
},
mutations: {
increment (state) {
state.countPP
}
},
actions: {
increment (context) {
context.commit('increment')
}
}
})ide/mutations.html" rel=" nofollow noreferrer "> Mutation
