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 //無需定義
3.actions里面寫事件（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:?{
????...mapActions({
??????logOutAction:?'logOut'
????}),
}
3.this.logOutAction(）
