如何使用id/name从json store中查找特定条目

// 假设JSON数据存储在变量jsonStore中
var jsonStore = {
  "items": [
    {
      "id": 1,
      "name": "item1",
      "description": "This is item 1"
    },
    {
      "id": 2,
      "name": "item2",
      "description": "This is item 2"
    },
    {
      "id": 3,
      "name": "item3",
      "description": "This is item 3"
    }
  ]
};

function findItemById(jsonStore, id) {
  for (var i = 0; i < jsonStore.items.length; i++) {
    if (jsonStore.items[i].id === id) {
      return jsonStore.items[i];
    }
  }
  return null; // 如果未找到匹配的条目，返回null或其他适当的值
}

function findItemByName(jsonStore, name) {
  for (var i = 0; i < jsonStore.items.length; i++) {
    if (jsonStore.items[i].name === name) {
      return jsonStore.items[i];
    }
  }
  return null; // 如果未找到匹配的条目，返回null或其他适当的值
}

// 使用示例
var itemId = 2;
var itemName = "item3";

var itemById = findItemById(jsonStore, itemId);
var itemByName = findItemByName(jsonStore, itemName);

console.log(itemById); // 输出: { id: 2, name: "item2", description: "This is item 2" }
console.log(itemByName); // 输出: { id: 3, name: "item3", description: "This is item 3" }
