Angular 从ag网格列获取复选框值

我在ag网格中有一个复选框，我以以下方式显示该复选框：

  {header: 'Cancel', 
    field: 'IsCancel', 
    cellRenderer: params => {
      return `<input type='checkbox' ${params.value ? 'checked': ''} />`
    }  
  }

以下是所有代码：

取消.component.html

<div *ngIf="loadCancellation">
  <ag-grid-angular class="ag-fresh"
    [columnDefs]="columnDefs"
    [rowData]="customerNames"
    (gridReady)="onGridReady($event)"
    class="ag-theme-balham">
  </ag-grid-angular>
  <br/>
  <button mat-raised-button color="primary" (click)="saveCustomer()">Save</button>
</div>

以下是更新的代码：

import { Component, Input, AfterViewInit, OnInit } from '@angular/core';
import { CustomerNameService } from '../customer-name.service';
import { CustomerNameCancellation } from '../customername-cancellation';
import { ColDef, GridApi, ColumnApi } from 'ag-grid-community';

@Component({
  selector: 'app-cancellation',
  templateUrl: './cancellation.component.html',
  styleUrls: ['./cancellation.component.css']
})
export class CancellationComponent implements OnInit {
  @Input('zipCode') zipCode: string;
  @Input('lastName') lastName: string;
  customerNames: Array<CustomerNameCancellation>;

  private api: GridApi;
  columnApi: ColumnApi;
  columnDefs: ColDef[];
  loadCancellation: boolean;
  params: any;

  constructor (private customerNameService: CustomerNameService) {
   this.columnDefs = this.createColumnDefs(); 
  }

  ngOnInit() {
    this.customerNameService
    .getCustomerNames(this.zipCode, this.lastName)
    .subscribe(data => {this.customerNames = data;})
    console.log("finished loading customers");
    console.log("zipcode is: " + this.zipCode);
    console.log("lastname is: " + this.lastName);
    this.loadCancellation = true;
  }

  onGridReady(params) : void {
    this.api = params.api;
    this.columnApi = params.columnApi;
    this.api.sizeColumnsToFit();
    this.params = params;
  }

  private createColumnDefs() {
    return [
      {headerName: 'Customer Number', field: 'CustomerNumber', sortable: true, filter: true},
      {headerName: 'First Name', field: 'FirstName', sortable: true, filter: true},
      {headerName: 'Middle Name', field: 'MiddleName', sortable: true, filter: true},
      {headerName: 'Last Name', field: 'LastName', sortable: true, filter: true},
      {headerName: 'Address', field: 'Address1', sortable: true, filter: true},
      {headerName: 'City', field: 'City', sortable: true, filter: true},
      {headerName: 'State', field: 'StateCd', sortable: true, filter: true},
      {headerName: 'Zip Code', field: 'ZipCode', sortable: true, filter: true},
      {headerName: 'Magazine Code', field: 'MagazineCd', sortable: true, filter: true},
      {headerName: 'Cancel', 
        field:'IsCancel',
        editable: true, 
        sortable: true,
        filter: true,
        checkboxSelection:true 
      },
      // {header: 'Cancel', 
      //   field: 'IsCancel', 
      //   cellRenderer: params => {
      //     return `<input type='checkbox' ${params.value ? 'checked': ''} "/>`
      //   }  
      // },
      {header: 'Cancellation Date', field: 'CancellationDate', sortable: true, filter: true}
    ]
  }

  saveCustomer() {
    // this.api.forEachNode(this.printNode)
    let selectedRows;
    selectedRows = this.api.getSelectedRows();
    console.log(selectedRows);
  }
}

从'@angular/core'导入{Component，Input，AfterViewInit，OnInit}；

从“../customername cancellation”导入{customername cancellation}；

//{标题：“取消”，

//返回“对于复选框选择，您可以在columnDef中使用checkboxSelection:true，而不是使用单元渲染：

this.columnDefs = [
  {
    headerName: 'Name',
    field: 'testName',
    checkboxSelection: true, //HERE !!!!
    width: 150
  }

选中复选框后，您可以轻松获取行：

someMethod() {
  let selectedRows;
  selectedRows = this.gridApi.getSelectedRows();
  console.log(selectedRows);
  ///than you can map your selectedRows 
  selectedRows.map((row) => {
   console.log(row);
   console.log(row.data);
  });
}

如果需要根据数据库中的数据设置“已检查”或“不依赖”，则可以使用：

     onGridReady(params) {
        this.gridApi = params.api;
        this.gridColumnApi = params.columnApi;
        this.transportApi.getCustomerNames().subscribe((res) => {
          this.rowData = res;
          if (res) {        
 this.transportApi.getSelectedCustomerNames().subscribe((selectedCustomers) => {
                if (selectedCustomers) {
                  this.gridApi.forEachNode((node) => {
                    selectedCustomers.map((customer) => {
                      if (node.data.CustomerNumber=== customer.CustomerNumber) {
                        node.setSelected(true);
                      }
                    });
                  });
                }
              });


            }
          }
        }, error1 => console.log(error1));
      }

传输方法是在代码中使用您的示例；
我已经尝试了checkboxSelection:true选项。我唯一不喜欢的是它显示“true”或“false”就在复选框旁边。请参阅原始帖子中的更新。我不明白，为什么需要使用cellRenderer进行复选框选择。尝试在不使用cellRenderer的情况下使用它。我尝试了“checkboxSelection:true”，但它也显示值“true”或“false”在复选框旁边。请查看我在原始帖子中包含的图像。不要使用cellRenderer进行复选框选择。简单添加复选框选择：true到要添加复选框的列。

  let selectedRows;
