演示组件.ts

import { Component } from '@angular/core';
import { ColDef, GridApi } from 'ag-grid-community';
import { TranslateService } from '@ngx-translate/core';

@Component({
  selector: 'app-demo',
  templateUrl: './demo.component.html',
  styleUrls: ['./demo.component.scss']
})
export class DemoComponent {
  private gridApi: GridApi = null;

  public columnDefs: ColDef[] = [
    { headerName: "Code", field: 'code', sortable: true, resizable: true, headerValueGetter: this.localizeHeader.bind(this) },
    { headerName: 'Version', field: 'version', sortable: true, resizable: true, headerValueGetter: this.localizeHeader.bind(this) },
    { headerName: 'IsEnabled', field: 'isEnabled', sortable: true, resizable: true, headerValueGetter: this.localizeHeader.bind(this) }
  ];

  public rowData: any[] = [];

  constructor(private translateService: TranslateService) {
    this.translateService.onLangChange.subscribe(() => {
      this.gridApi.refreshHeader();
    })
  }

  public onGridReady(parameters: any): void {
    this.gridApi = parameters.api;
  }

  public localizeHeader(parameters: ICellRendererParams): string {
    let headerIdentifier = parameters.colDef.field;
    return this.translateService.instant(headerIdentifier);
  }
}

标题值获取器

使用headerValueGetter代替colDef.headerName以允许动态标头名称。

private translator: TranslateService;
...
colDef.headerValueGetter : this.localizeHeader.bind(this)
....
localizeHeader(params){
    let headerIdentifier = params.colDef.field; // params.column.getColId();
    this.translator.get(headerIdentifier).map((res: string) => {
        return res;
    });
}

文件中的样本

{ 
    headerName: "Country", 
    field: "country", 
    width: 120, 
    enableRowGroup: true, 
    enablePivot: true, 
    headerValueGetter: countryHeaderValueGetter 
},

function countryHeaderValueGetter(params) {
    switch (params.location) {
        case 'csv': return 'CSV Country';
        case 'clipboard': return 'CLIP Country';
        case 'toolPanel': return 'TP Country';
        case 'columnDrop': return 'CD Country';
        case 'header': return 'H Country';
        default: return 'Should never happen!';
    }
}

如果你想使用TurboYang的异步翻译加载解决方案，只需添加以下内容：

private destroy = new Subject<void>();

  constructor(private toastService: ToastService, private translate: TranslateService) {
    translate.onLangChange.pipe(takeUntil(this.destroy)).subscribe(() => {
      this.gridApi.refreshHeader();
    });
    translate.onDefaultLangChange.pipe(takeUntil(this.destroy)).subscribe(() => {
      this.gridApi.refreshHeader();
    });
  }

  ngOnDestroy(): void {
    this.destroy.next();
    this.destroy.complete();
  }

使用中的功能

getTr(key: string) {
    return this.translate.instant(key);
  }

列定义中的用法

{
    field: 'name', headerName: this.trService.getTr('NAME')
  },
