Angular 6 ag-grid cell renderer click function

问题

So I'm trying to setup ag-grid and I can't get one thing to work. I want to have a column that is actions. Then I want it to have a link or button that triggers a method in the component file.

For the column def I have the following. What am I doing wrong?

 {
    headerName: 'Actions',
    cellRenderer: params => {
      return `<a (click)="onEditClick("${params.data.hostname}")">Edit</a>`;
    }
 }

回答1:

I use cellRenderFramework:

    {
    headerName: '', width: 30,
    cellRendererFramework: ActionCellRendererComponent,
    cellRendererParams: {
      icon: 'fa-download',
      action: this.downloadAttachmentAction
    }
  }

and than I have custom Component

@Component({
  selector: 'cu-download-link-cell-renderer',
  template: `
  <div class="text-center">
    <i class="fa {{params.icon}}" (click)="onClick()" aria-hidden="true"></i>
  </div>`
})
export class ActionCellRendererComponent {

    params;

    constructor() {
    }

    agInit(params): void {
        this.params = params;
        if (_.isNil(params.action)) {
            throw new Error('Missing action parameter for ActionCellRendererComponent');
       }
   }

   onClick(): void {
       this.params.action(this.params);
   }
}

export type CellAction = (params) => void;

Use cellRendererFramework to add action Buttons.

App.component.ts

columnDefs = [
  { headerName: 'First Name', field: 'firstName', sortable: true, filter: true },
  { headerName: 'Last Name', field: 'lastName', sortable: true, filter: true },
  { headerName: 'Email', field: 'email', sortable: true, filter: true },
  { headerName: 'User Name', field: 'userIdName', sortable: true, filter: true },
  { headerName: 'Role', field: 'role', sortable: true, filter: true },
  { headerName: 'Actions', field: 'action', cellRendererFramework: CellCustomComponent }];

rowData: any;

ngOnInit() {
  const empDatas = localStorage.getItem('user');
  const finalData = JSON.parse(this.empDatas);
  this.rowData = this.finalData;
}

In the above code, we can see CellCustomComponent. Create that component & add the buttons.

cell-custom.component.html

<button type="button" class="btn-success" (click)="editRow()">Edit</button>
<button type="button" class="btn-success" (click)="viewRow()">View</button>

Now in the cell-custom.component.ts add the functions

cell-custom.component.ts

export class CellCustomComponent implements OnInit {
  data: any;
  params: any;
  constructor(private http: HttpClient, private router: Router) {}

  agInit(params) {
    this.params = params;
    this.data = params.value;
  }

  ngOnInit() {}

  editRow() {
    let rowData = this.params;
    let i = rowData.rowIndex;
    console.log(rowData);
  }

  viewRow() {
    let rowData = this.params;
    console.log(rowData);
  }
}

After this we need to add this component in App.module.ts

app.Module.ts

@NgModule({
  declarations: [AppComponent, CellCustomComponent],
  imports: [
    BrowserModule,
    AppRoutingModule,
    FormsModule,
    HttpClientModule,
    AgGridModule.withComponents([AppComponent])
  ],
  providers: [],
  entryComponents: [CellCustomComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

Now we can trigger a method in the component file using Button.
