javascript - 尝试过滤 JSON

Question

我正在尝试使用 JSON.filter() 过滤 JSON，但我的代码是错误的，我尝试了一些变体，但都失败了。有人可以告诉我我做错了什么吗？

;(async function () {
    const result = await transform(xml, template);
    const prettyStr = await prettyPrint(xml, { indentSize: 4});
    const filterActive = JSON.filter(result, products.active === 'true');
    fs.writeFileSync('./temp/converted.json', JSON.stringify(result));
});

这是没有过滤器时输出的 JSON:

{
    "products": [
        {
            "id": "60000000425",
            "sku": "0135363004",
            "active": "false",
            "brand": "BROWNING",
            "description": "725 HUNTER 12G 28\" M/C",
            "price": "1719.0000",
            "category": "1",
            "department": "1"
        },
        {
            "id": "60000000000",
            "sku": "00100",
            "active": "true",
            "brand": "",
            "description": "ELEY 22 TENEX",
            "price": "0.2600",
            "category": "8",
            "department": "3"
        },

你需要做的:

const filterActive = result.products.filter(({active}) => active === 'true');

var result = {
  "products": [{
      "id": "60000000425",
      "sku": "0135363004",
      "active": "false",
      "brand": "BROWNING",
      "description": "725 HUNTER 12G 28\" M/C",
      "price": "1719.0000",
      "category": "1",
      "department": "1"
    },
    {
      "id": "60000000000",
      "sku": "00100",
      "active": "true",
      "brand": "",
      "description": "ELEY 22 TENEX",
      "price": "0.2600",
      "category": "8",
      "department": "3"
    }
  ]
};

const filterActive = result.products.filter(({active}) => active === 'true');

console.log(filterActive);
