错误代码

let store = new Vuex({
  state: {
    totalPrice: 0
  },
  mutations: {
    increment (state, price) {
      state.totalPrice += price
    },
    decrement (state, price) {
      state.totalPrice -= price
    }
  }
})

正确代码：

let store = new Vuex.Store({
  state: {
    totalPrice: 0
  },
  mutations: {
    increment (state, price) {
      state.totalPrice += price
    },
    decrement (state, price) {
      state.totalPrice -= price
    }
  }
})

分析：构造器写法写错了应该是new Vuex.Store({})

下面请忽略。。

 
   let 
   store = 
   new 
   Vuex({ 
  
   state: { 
  
   totalPrice: 
   0 
  
    }, 
  
   mutations: { 
  
   increment ( 
   state, 
   price) { 
  
   state. 
   totalPrice += 
   price 
  
    }, 
  
   decrement ( 
   state, 
   price) { 
  
   state. 
   totalPrice -= 
   price 
  
    } 
  
    } 
  
    })
