vue中store用法

1 在store文件夹下面创建js

const workflows = {
  state: {
    save: false
  },
  mutations: {
    SET_SAVE(state, obj) {
      state.save = obj
    }
  },
  actions: {
    setSave({ commit }, obj) {
      commit('SET_SAVE', obj)
    }
  }
}

export default workflows

2 设置值

 this.$store.commit('SET_SAVE', true)

3 获取值

用法1

computed:{
  showSave(){
    return this.$store.state.workflows.save
   }
}

用法2

<div v-if="cmBaseIsTip"></div>
  computed: {
    ...mapGetters(['cmBaseIsTip'])
  },
