如何删除数组中的项目有2个id，id product和id product detail。当我点击要删除的产品时，redux选择数组1中的id来删除并删除所有产品详细信息。我想删除product detail而不是数组1中的产品
这是我的cartSlice.js在redux中

import { createSlice } from '@reduxjs/toolkit';

const cartSlice = createSlice({
  name: 'cart',
  initialState: {
    cart: [],
  },
  reducers: {
    addToCart: (state, action) => {
      const itemInCart = state.cart.find((item) => item.id === action.payload.id && item.idProduct === action.payload.idProduct);
      if (itemInCart) {
        itemInCart.quantity++;
      } else {
        state.cart.push({ ...action.payload, quantity: 1 });
      }
    },
    incrementQuantity: (state, action) => {
      const item = state.cart.find((item) => item.id === action.payload);
      item.quantity++;
    },
    decrementQuantity: (state, action) => {
      const item = state.cart.find((item) => item.id === action.payload);
      if (item.quantity === 1) {
        item.quantity = 1
      } else {
        item.quantity--;
      }
    },
    removeItem: (state, action) => {
        const removeItem = state.cart.filter((item) => 
            item.id !== action.payload 
            
        );

        state.cart = removeItem;
    },
  },
});

export const cartReducer = cartSlice.reducer;
export const {
  addToCart,
  incrementQuantity,
  decrementQuantity,
  removeItem,
} = cartSlice.actions;

您应该将两个id（productId和productDetailId）都传递给removeItem reducer函数。

removeItem: (state, action) => {
        const {productId, productDetailId} = action.payload;
        const selectedProduct = state.cart.find((item) => item.id === productId);
        if(Array.isArray(selectedProduct?.product_details)) {
          selectedProduct.product_details = selectedProduct.product_details.filter(item => item.id !== productDetailId);
        } 
    },

基本上，我们正在做的是：
1.查找具有给定产品ID的产品
1.在选定（找到）的产品中，删除产品详细信息ID。
要调用，请调用以下命令：

dispatch(removeItem({
  productId: "yyy",
  productDetailId: "zzz"
}))

希望这样能解决问题。
谢谢
