如何从具有公共键：值对的 object 数组中制作单个 object

Question

我有一些数据

var list =[{date: "2019-09-27T08:00", atmosphericpressure: 80.58},
{date: "2019-09-27T08:00", lightningdistance: 0},
{date: "2019-09-27T08:00", lightningevents: 0},
{date: "2019-09-27T08:00", precipitation: 0},
{date: "2019-09-27T08:00", radiation: 829.03},
{date: "2019-09-27T08:00", relativehumidity: 0.78},
{date: "2019-09-27T08:00", temperature: 20.24},
{date: "2019-09-27T08:00", winddirection: 56.43},
{date: "2019-09-27T08:00", windgusts: 3.78},
{date: "2019-09-27T08:00", windspeed: 1.73},

{date: "2019-09-27T09:00", atmosphericpressure: 80.5},
{date: "2019-09-27T09:00", lightningdistance: 0},
{date: "2019-09-27T09:00", lightningevents: 0},
{date: "2019-09-27T09:00", precipitation: 0},
{date: "2019-09-27T09:00", radiation: 739.98},
{date: "2019-09-27T09:00", relativehumidity: 0.74},
{date: "2019-09-27T09:00", temperature: 20.82},
{date: "2019-09-27T09:00", winddirection: 52.83},
{date: "2019-09-27T09:00", windgusts: 2.95},
{date: "2019-09-27T09:00", windspeed: 1.54}]

我想把它改造成

var list =[
   { 
    date: '2019-09-27T08:00',
    atmosphericpressure: 80.58,
    lightningdistance: 0,
    lightningevents: 0,
    precipitation: 0,
    radiation: 829.03,
    relativehumidity: 0.78,
    temperature: 20.24,
    winddirection: 56.43,
    windgusts: 3.78,
    windspeed: 1.73
},
{
date: '2019-09-27T09:00',
    atmosphericpressure: 80.5,
    lightningdistance: 0,
    lightningevents: 0,
    precipitation: 0,
    radiation: 739.98,
    relativehumidity: 0.74,
    temperature: 22.82,
    winddirection: 52.83,
    windgusts: 2.95,
    windspeed: 1.54
}
]

我试过使用这样的过滤器

let temp=[]
   let result = list.filter(obj => {
  if(obj.date === '2019-09-27T09:00'){
   let group= {
     date:obj.date,
    atmosphericpressure:obj.atmosphericpressure,
    lightningdistance:obj.lightningdistance,
    lightningevents:obj.lightningevents,
    precipitation:obj.precipitation,
    radiation:obj.radiation,
    relativehumidity:obj.relativehumidity,
    temperature:obj.temperature,
    winddirection:obj.winddirection,
    windgusts:obj.windgusts,
    windspeed:obj.windspeed
    }
    temp.push(group)
  }
})

console.log(temp)

但结果不是我想要的，我得到以下

我真的需要一些关于如何实现这一目标的见解，请任何人帮助。 我还附上了我当前实现的片段，以便很容易看到我在做什么

Answer 1

您可以使用数组 forEach 来实现您想要的

 var list =[{date: "2019-09-27T08:00", atmosphericpressure: 80.58}, {date: "2019-09-27T08:00", lightningdistance: 0}, {date: "2019-09-27T08:00", lightningevents: 0}, {date: "2019-09-27T08:00", precipitation: 0}, {date: "2019-09-27T08:00", radiation: 829.03}, {date: "2019-09-27T08:00", relativehumidity: 0.78}, {date: "2019-09-27T08:00", temperature: 20.24}, {date: "2019-09-27T08:00", winddirection: 56.43}, {date: "2019-09-27T08:00", windgusts: 3.78}, {date: "2019-09-27T08:00", windspeed: 1.73}, {date: "2019-09-27T09:00", atmosphericpressure: 80.5}, {date: "2019-09-27T09:00", lightningdistance: 0}, {date: "2019-09-27T09:00", lightningevents: 0}, {date: "2019-09-27T09:00", precipitation: 0}, {date: "2019-09-27T09:00", radiation: 739.98}, {date: "2019-09-27T09:00", relativehumidity: 0.74}, {date: "2019-09-27T09:00", temperature: 20.82}, {date: "2019-09-27T09:00", winddirection: 52.83}, {date: "2019-09-27T09:00", windgusts: 2.95}, {date: "2019-09-27T09:00", windspeed: 1.54}] const result = []; list.forEach(i => { let x = result.find(r => r.date === i.date); if(x) { Object.assign(x, i); } else { result.push(i); } }); console.log(result);

Answer 2

问题：

您在每次迭代中为所有 object 属性分配值。 在每次迭代中，您将获得单个属性的值。 所有其他值将是未定义的。 所以剩余的值每次都会被 undefined 覆盖。

解决方法

不要手动分配给所有值，而是使用temp[index][Object.keys(obj)[1]] = Object.values[obj][1])

我使用了 function 来减少一些代码。

编码：

let temp=[];
function addData(pos,obj){ 
// a function to add the property to object at given position
  temp[pos][Object.keys(obj)[1]] = Object.values(obj)[1];
}
list.forEach((o) => { // Initialize the array with available dates
  if(!temp.find((d)=> d.date==o.date)){
    temp.push({"date":o.date});
  }
});
list.forEach((o) => { // Looping through each object
 temp.forEach((d) => { // looping through temp to find the position in temp
  if(o.date == d.date){
    window.addData(temp.indexOf(d),o);
  }
 }); 
});
console.log(temp)

Answer 3

这是一个有效的JFiddle

我在这段代码中添加了一些注释。

let newList = [];
let currKey = "";
let currObj = {};
list.forEach(function(e,i) {
    if(currKey != e.date) {//How we will identify
    currKey = e.date;
    if(i != 0) //Prevents empty first space
        newList[newList.length] = currObj; //Adds object to new list
    currObj = {}; //Gives new starting point
    currObj.date = e.date;
  }

  if(currKey == e.date) {
    Object.keys(e).forEach(function(prop) {
        if(e != 'date')
        currObj[prop] = e[prop]; //Copies over the value
    });
  }
    if(i == list.length-1)
    newList[newList.length] = currObj; //Adds last object to list
});

console.log(newList);
