javascript过滤一个对象

Question

我有以下 Javascript 对象。var data = {  "type": [    "car",    "bike"  ],  "wheels": [    "4",    "2"  ],  "open": [    "Jan",    "Jan"  ],  "wheel_press": [    "35",    "19"  ],  "max-weight": [    "4000",    "8"  ],  "transition_plan": [    "",    null  ],  "number_of_occurence": [    5696,    976  ],  "model": [    "sedan",    "street"}我想过滤任何对象键以仅获取该键的相应值。到目前为止，在搜索 stackoverflow 后仍然无法找到类似的问题。我试过使用data.filter(type ==='car')我得到的错误是.filter is not a function预期的输出是如果我过滤 type === 'car' 那么它应该只显示{  "type": [    "car"  ],  "wheels": [    "4"  ],  "open": [    "Jan"  ],  "wheel_press": [    "35"  ],  "max-weight": [    "4000"  ],  "transition_plan": [    ""  ],  "number_of_occurence": [    5696  ],  "model": [    "sedan"}

Answer 1

您可以编写一个函数来查找给定属性内的值的索引，然后使用Object.fromEntries(),Object.keys()并Array.map()创建一个新对象，如下所示

var data={type:["car","bike"],wheels:["4","2"],open:["Jan","Jan"],wheel_press:["35","19"],"max-weight":["4000","8"],transition_plan:["",null],number_of_occurence:[5696,976],model:["sedan","street"]};

const getFilteredObject = (property, value) => {

  const index = data[property].indexOf(value)

  

  return Object.fromEntries(Object.keys(data).map(key => ([key, data[key][index]])))

}

const filteredObject = getFilteredObject('type','car');

console.log(filteredObject)
