1.取state的值（mapState）

1.import?{?mapState?}?from?'vuex'

2. computed:?{

????...mapState({

??????foodData:?state?=>?state.food_list,

??????table:?state?=>?state.table,

??????user:?state?=>?state.user

????})

}

3.this.table

2.保存值（mapMutations?）

注：setTable:?(state,?table)?=>?{

??????state.table?=?table

????},

1.import?{ mapMutations?}?from?'vuex'

2.methods:?{

????...mapMutations([

??????'setTable'

????]),

}

3.this.setTable //無(wú)需定義

3.actions里面寫(xiě)事件（mapActions）

注：logOut?({?commit?})?{

??????return?new?Promise((resolve)?=>?{

????????this._vm.$post('/storeapp/login/loginout').then((res)?=>?{

??????????commit('foodList',?'')

??????????commit('setUser',?'')

??????????resolve()

????????}).catch(()?=>?{

??????????commit('foodList',?'')

??????????commit('setUser',?'')

????????})

??????})

????}

1.import?{ mapActions?}?from?'vuex'

2.methods:?{
