如何使用 ag 网格中列的值创建数组？

Question

我有具有以下值的列：

export class AppComponent {
private gridApi;
private gridColumnApi;

private columnDefs;
private rowData;
private defaultColDef;
private getRowNodeId;

constructor() {
this.columnDefs = [
  {
    headerName: "Make",
    field: "make"
  },
  {
    headerName: "Model",
    field: "model"
  },
  {
    headerName: "Price",
    field: "price",
    filter: "agNumberColumnFilter"
  }
];
this.rowData = [
  {
    id: "aa",
    make: "Toyota",
    model: "Celica",
    price: 35000
  },
  {
    id: "bb",
    make: "Ford",
    model: "Mondeo",
    price: 32000
  },
  {
    id: "cc",
    make: "Porsche",
    model: "Boxter",
    price: 72000
  },
  {
    id: "dd",
    make: "BMW",
    model: "5 Series",
    price: 59000
  },
  {
    id: "ee",
    make: "Dodge",
    model: "Challanger",
    price: 35000
  },
  {
    id: "ff",
    make: "Mazda",
    model: "MX5",
    price: 28000
  },
  {
    id: "gg",
    make: "Horse",
    model: "Outside",
    price: 99000
  }
];
this.defaultColDef = {
  editable: true,
  sortable: true,
  filter: true
};
this.getRowNodeId = function(data) {
  return data.id;
};

}

如何将 'Price' 列中的值存储到数组中？

澄清一下，我想要一个包含 'Price' 值的数组 - 有点像这样：

var exampleArray = [35000,32000,72000,59000,35000,28000,99000]

恐怕目前从 AG-Grid 获取所有数据的方式相当不直观。如果你想从你的农业网格中获取数据，你必须做这样的事情。不要忘记在组件中初始化 gridApi！在你的 component.html

 <ag-grid-angular (gridReady)="onGridReady($event)" ... ></ag-grid-angular>

在你的 component.ts、

onGridReady(params) {
  this.gridApi = params.api;
}
 .
 .
getRowData() {
  let rowData = [];
  this.gridApi.forEachNode(node => rowData.push(node.data));
  console.log(rowData)
}

为了获得一组价格，您可以接下来这样做：

const pricesArray = rowData.map(row => row['price']);
console.log(pricesArray);
