Question

基于过滤器对象，我需要过滤掉数据。以下是具有所需输出的过滤器对象和示例数据。过滤器对象是通过 ui 中的多搜索组件动态生成的。然后当用户点击搜索时需要过滤数据。

var filter = {
  city: 'pana',
  hospname: 'sara'
};
var data = [
  {
    "city": "Hot Springs",
    "hospname": "St. Vincent Hot Springs",
    "version": "VA48A",
    "sysid1": "CT67400",
    "type": "CompressedFile",
    "rowIndex": 0,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Panama City",
    "hospname": "Bay Medical Center",
    "version": "VA48A",
    "sysid1": "CT67399",
    "type": "CompressedFile",
    "rowIndex": 1,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Sarasota",
    "hospname": "Sarasota Memorial Hospital",
    "version": "VA44A",
    "sysid1": "C7393",
    "type": "CompressedFile",
    "rowIndex": 2,
    "selected": false,
    "disabled": true
  },
  {
    "city": "DAVENPORT",
    "hospname": "Genesis Medical Center",
    "version": "VA48A",
    "sysid1": "C6333",
    "type": "CompressedFile",
    "rowIndex": 6,
    "selected": false,
    "disabled": true
  }
];

预期输出：

[{
    "city": "Panama City",
    "hospname": "Bay Medical Center",
    "version": "VA48A",
    "sysid1": "CT67399",
    "type": "CompressedFile",
    "rowIndex": 1,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Sarasota",
    "hospname": "Sarasota Memorial Hospital",
    "version": "VA44A",
    "sysid1": "CT67393",
    "type": "CompressedFile",
    "rowIndex": 2,
    "selected": false,
    "disabled": true
  }]

var filter = {
  city: 'pana',
  hospname: 'sara'
};
var data = [
  {
    "city": "Hot Springs",
    "hospname": "St. Vincent Hot Springs",
    "version": "VA48A",
    "sysid1": "CT67400",
    "type": "CompressedFile",
    "rowIndex": 0,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Panama City",
    "hospname": "Bay Medical Center",
    "version": "VA48A",
    "sysid1": "CT67399",
    "type": "CompressedFile",
    "rowIndex": 1,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Sarasota",
    "hospname": "Sarasota Memorial Hospital",
    "version": "VA44A",
    "sysid1": "C7393",
    "type": "CompressedFile",
    "rowIndex": 2,
    "selected": false,
    "disabled": true
  },
  {
    "city": "DAVENPORT",
    "hospname": "Genesis Medical Center",
    "version": "VA48A",
    "sysid1": "C6333",
    "type": "CompressedFile",
    "rowIndex": 6,
    "selected": false,
    "disabled": true
  }
];

const result=data.filter(item=>item.city.toLowerCase().includes(filter.city.toLowerCase()) || item.hospname.toLowerCase().includes(filter.hospname.toLowerCase()) )

console.log(result)

.as-console-wrapper { max-height: 100% !important; top: 0; }

我开始使用更通用的版本，您可以在其中为过滤器对象添加属性。

var filter = {
  city: 'pana',
  hospname: 'sara'
};
var data = [
  {
    "city": "Hot Springs",
    "hospname": "St. Vincent Hot Springs",
    "version": "VA48A",
    "sysid1": "CT67400",
    "type": "CompressedFile",
    "rowIndex": 0,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Panama City",
    "hospname": "Bay Medical Center",
    "version": "VA48A",
    "sysid1": "CT67399",
    "type": "CompressedFile",
    "rowIndex": 1,
    "selected": false,
    "disabled": true
  },
  {
    "city": "Sarasota",
    "hospname": "Sarasota Memorial Hospital",
    "version": "VA44A",
    "sysid1": "C7393",
    "type": "CompressedFile",
    "rowIndex": 2,
    "selected": false,
    "disabled": true
  },
  {
    "city": "DAVENPORT",
    "hospname": "Genesis Medical Center",
    "version": "VA48A",
    "sysid1": "C6333",
    "type": "CompressedFile",
    "rowIndex": 6,
    "selected": false,
    "disabled": true
  }
];

let results;

if (Object.keys(filter).length === 0)
  results = data;
else {
  results = data.filter((item) => {
      return Object.keys(filter).find(key => {
          return item[key] && item[key].toLowerCase().includes(filter[key].toLowerCase());
      });
  });  
}

console.log(results);

在 ES6 中你可以这样做

var results = data.filter(function(item)=>{
   return item.city === filter.city || item.hospname === filter.hospname;
});

快乐编码！
