import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({

	},
	mutations: {
		upMemberType(state,type){
			state.memberType = type
		}
	},
	actions: {

	}

});

export default store

import {mapGetters} from "vuex";
export default {
	computed: mapGetters(['getName']),
	data() {
