为什么我的删除功能不是删除我点击的实际产品,而是删除其他产品,但当我console.log()项目时,它显示正确的ObjectId
这是我的按钮,我传递idprice

<Button color="error" 
 onClick={() => handleClick(product._id, product.price)} startIcon= 
{<DeleteIcon />} 
variant="contained">
Remove
</Button>

我正在使用的函数。

const handleClick =(id,price) =>{
        const itemPrice = Number(price)
        dispatch(deleteProduct({id,quantity: cart.quantity, price: itemPrice}))
    }

cartSlice.js

const cartSlice = createSlice({
    name: "cart",
    initialState: {
    products: [],
    quantity: 0,
    total: 0
    },
    reducers: {
        resetStateCart: (state) => {
            state.products = [];
            state.quantity = 0;
            state.total = 0
        },
        addProduct: (state,action) =>{
            state.quantity += 1;
            state.products.push(action.payload);
            state.total += action.payload.price * action.payload.quantity
        },
        deleteProduct: (state,action) =>{
            state.quantity -= 1;
            state.products.splice(state.products.findIndex((arrow) => arrow._id === action.payload),1)
            state.total = (action.payload.quantity-1) * action.payload.price
        }
    }

})

例如,我删除了product 1 2

但其他产品被删除

在您的deleteProduct方法中存在问题。您是否匹配发送对象{id,quantity:购物车.数量,价格:itemPrice}在方法中.而不是与产品id比较,你将它与整个有效负载比较.它应该是action.payload. id.在你的情况状态.products.findIndex((arrow)=〉arrow._id === action.payload)return-1所以splice删除状态中的最后一个产品.products
