javascript - 过滤对象键上的数组不为空

Question

我正在尝试通过值不为空的对象键来过滤对象数组

var collection = [
                      {
            "season": "ETE 18",
            "group": "GRBABY",
            "market": "ALL",
            "department": "ALL",
            "skuType": "ALL",
            "orderType": "ASE",
            "packagingType": "CI"
        },
        {
            "season": "ETE 18",
            "group": "MEN",
            "market": "ALL",
            "department": "ALL",
            "skuType": "ALL",
            "orderType": "ASE",
            "packagingType": "CI"
        },
        {
            "season": "ETE 18",
            "group": "GRBABY",
            "market": "NONE",
            "department": "ALL",
            "skuType": "ALL",
            "orderType": "ASE",
            "packagingType": "CI"
        },
                     ]

      var filterList = {season: "", group: "GRBABY", market: "ALL", department: "", 
          skuType: ""}

      var result = _.filter(collection , proPack => {
                          if (filterList.group !== '') {
                              return proPack.group === filterList.group;
                          } else {
                              return proPack;
                          }
                    });
                    
                    console.log(result)

这对我来说适用于一个过滤器，但我无法找到一种方法来过滤所有其他具有值的键。

结果应该是:

result = [
              {
    "season": "ETE 18",
    "group": "GRBABY",
    "market": "ALL",
    "department": "ALL",
    "skuType": "ALL",
    "orderType": "ASE",
    "packagingType": "CI"
} ]

您可以删除空属性:

var collection = [{
    "season": "ETE 18",
    "group": "GRBABY",
    "market": "ALL",
    "department": "ALL",
    "skuType": "ALL",
    "orderType": "ASE",
    "packagingType": "CI"
  },
  {
    "season": "ETE 18",
    "group": "MEN",
    "market": "ALL",
    "department": "ALL",
    "skuType": "ALL",
    "orderType": "ASE",
    "packagingType": "CI"
  },
  {
    "season": "ETE 18",
    "group": "GRBABY",
    "market": "NONE",
    "department": "ALL",
    "skuType": "ALL",
    "orderType": "ASE",
    "packagingType": "CI"
  }
]

var filterList = {season: "", group: "GRBABY", market: "ALL", department: "", 
          skuType: ""}
          
var filterList = _.omitBy(filterList, _.isEmpty)   // { group: "GRBABY", market: "ALL" }

var result = _.filter(collection, filterList)

console.log(filterList, result)
