Arrays TS：自定义对象数组的定义

这是我的数组定义（可能有问题。我想说这个数组将是一个自定义对象数组）：

那么我想填一下：

  this.grid.gridView.data.forEach(element => {
      records.push(element.LicencePlate, element.Description, element.DateOfStartUse.toLocaleDateString('en-GB'),
      element.Base, element.Active);
    });

我想得到这样的东西——对象数组

[{"Johnny", "Actor", "05/03/2000", "Holywood", true}, 
 {"Kirk", "Musician", "01/06/1999", "California", true}, 
 {"Elvis", "Singer", "15/09/1975", "Mississippi", false}]

但我只得到了一个长的单值数组：

["Johnny", "Actor", "05/03/2000", "Holywood", true, 
"Kirk", "Musician", "01/06/1999", "California", true, 
"Elvis", "Singer", "15/09/1975", "Mississippi", false]

我哪里出错了？

每次迭代都需要将新对象推入数组

比如：

this.grid.gridView.data.forEach(element => {
  // create object for this row
  const o = {
    LicencePlate: element.LicencePlate,
    Description: element.Description,
    /// other properties and values
  }
  // push that object to array
  records.push(o);
});

-编辑Oops，这是js，您需要ts。。漠视我把这个留在这里

除了charlietfl的回答之外

arr.push（element1[，…[，elementN]]）

您希望在末尾将单个元素推入数组索引

但是您正在将元素的每个字段按新索引推入数组中

charlietfl的回答实质上是创建每个元素的浅副本，
您也可以直接推动该元素：

let records = []; //or new Array();
//typescript will let you do new Array<Record>(), but not in javascript

this.grid.gridView.data.forEach(element => {
  records.push(element);
});

let records=[]//或新数组（）；
//typescript将允许您执行新数组（），但不能使用javascript
this.grid.gridView.data.forEach（元素=>{
记录。推送（元素）；
});

我对记录的执行情况：

//An implementation of your record object (you apparently already have these, so you don't need it)
class Record {
  constructor (licensePlate) {
    this.licensePlate = licensePlate;
    this.description = description;
    this.setToUse = setToUse;
    this.depot = depot;
    this.active = active;
  }
}

let records = new Array(); //In typescript we can have Array<Record> for typed array, but not in js :(

//I'm creating a test record here because I don't have your gridView code
let rec = new Record("BLAHBLAH", "A record example instance", "some kind of set to use", "a depot", false);

records.push(rec); //Push the record instance|object into the array

//this.grid.gridView.data.forEach(element => {
//  records.push(element.LicencePlate, element.Description, element.DateOfStartUse.toLocaleDateString('en-GB'),
//  element.Base, element.Active);
//});

//记录对象的实现（显然您已经有了这些，所以不需要它）
课堂记录{
建造商（牌照）{
this.licensePlate=licensePlate；
this.description=描述；
this.settuse=settuse；
this.depot=仓库；
这个.active=active；
}
}
让记录=新数组（）//在typescript中，我们可以将数组用于类型化数组，但在js中不能：(
//我在这里创建一个测试记录，因为我没有您的gridView代码
让rec=新记录（“BLAHBLAH”，“记录示例实例”，“要使用的某种集合”，“仓库”，false）；
records.push（rec）；//将记录实例|对象推入数组
//this.grid.gridView.data.forEach（元素=>{
//records.push（element.licenseplate、element.Description、element.DateOfStartUse.toLocaleDateString（'en-GB'），
//element.Base，element.Active）；
//});

//An implementation of your record object (you apparently already have these, so you don't need it)
class Record {
  constructor (licensePlate) {
    this.licensePlate = licensePlate;
    this.description = description;
    this.setToUse = setToUse;
    this.depot = depot;
    this.active = active;
  }
}

let records = new Array(); //In typescript we can have Array<Record> for typed array, but not in js :(

//I'm creating a test record here because I don't have your gridView code
let rec = new Record("BLAHBLAH", "A record example instance", "some kind of set to use", "a depot", false);

records.push(rec); //Push the record instance|object into the array

//this.grid.gridView.data.forEach(element => {
//  records.push(element.LicencePlate, element.Description, element.DateOfStartUse.toLocaleDateString('en-GB'),
//  element.Base, element.Active);
//});
