錯誤代碼
let store = new Vuex({
state: {
totalPrice: 0
},
mutations: {
increment (state, price) {
state.totalPrice += price
},
decrement (state, price) {
state.totalPrice -= price
}
}
})
正確代碼：
let store = new Vuex.Store({
state: {
totalPrice: 0
},
mutations: {
increment (state, price) {
state.totalPrice += price
},
decrement (state, price) {
state.totalPrice -= price
}
}
})
分析：構造器寫法寫錯了應該是new Vuex.Store({})
下面請忽略。。
let
store =
new
Vuex({
state: {
totalPrice:
0
},
mutations: {
increment (
state,
price) {
state.
totalPrice +=
price
},
decrement (
state,
price) {
state.
totalPrice -=
price
}
}
})
