在对象数组内的数组中查找字符串

lodash javascript-objects string arrays

我有一个复杂的对象声明性配置数组,我需要从中获取一些数据。这是我的数组:

units = [{
    'hpid': '787',
    'hpr': 'Hotel Apartamento Solverde',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': [],
      'PRODUCT': [],
      'SEARCH': [],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '130',
    'hpr': 'Hotel Algarve Casino',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': ['/hotel-algarve-casino/'],
      'PRODUCT': [
        '/hotel-algarve-casino/quartos/quarto-standard-vista-avenida/',
        '/hotel-algarve-casino/quartos/quarto-superior-vista-mar/',
        '/hotel-algarve-casino/quartos/quarto-familiar-vista-mar/',
        '/hotel-algarve-casino/quartos/suite-vista-avenida/',
        '/hotel-algarve-casino/quartos/suite-vista-mar/',
      ],
      'SEARCH': [
        '/hotel-algarve-casino/quartos/',
        '/en/hotel-algarve-casino/rooms/'
      ],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '300',
    'hpr': 'Hotel Casino Chaves',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': ['/hotel-casino-chaves/'],
      'PRODUCT': [
        '/hotel-casino-chaves/quartos/quarto-standard-vista-avenida/',
        '/hotel-casino-chaves/quartos/quarto-superior-vista-mar/',
        '/hotel-casino-chaves/quartos/quarto-familiar-vista-mar/',
        '/hotel-casino-chaves/quartos/suite-vista-avenida/',
        '/hotel-casino-chaves/quartos/suite-vista-mar/',
      ],
      'SEARCH': [
        '/hotel-casino-chaves/quartos/',
        '/en/hotel-casino-chaves/rooms/'
      ],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '759',
    'hpr': 'Hotel Solverde Spa and Wellness Center',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': [],
      'PRODUCT': [],
      'SEARCH': [],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }
];

并且需要找到包含字符串ex: /en/hotel-casino-chaves/rooms/

此外,我还需要上一次搜索的“hpid”属性的值。

我感谢你的帮助。谢谢

那么我需要找到

这应该会奏效:

在的回调中 Array.reduce 检查当前元素是否 c 中的一个或多个阵列 c.pt 包含搜索字符串。

如果是,请添加 c.hpid 以及将包含搜索字符串的属性的名称添加到结果中。

      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }
];


let result = units.reduce((a,c) => {
  let entries = Object.entries(c.pt)
    .filter(y => y[1].includes('/en/hotel-casino-chaves/rooms/'));
    
  for (let e of entries) {
    a.push({ hpid: c.hpid, prop: e[0]});
  }
  return a;
}, []);

console.log(result);
