Question

我得到＆＃34; TypeError：无法读取属性＆＃39;订阅＆＃39;未定义＆＃34;后我已经设置了MdPaginatorIntl提供程序，如下所示：

app.module.ts

import { MaterialModule, MdPaginatorIntl } from '@angular/material';
import { mdPaginatorIntlRo } from './i18l/mdPaginatorIntl';
...
@NgModule({
  ...
  providers: [
    { provide: MdPaginatorIntl, useClass: mdPaginatorIntlRo },
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

./ i18l / mdPaginatorIntl.ts

export class mdPaginatorIntlRo {
    itemsPerPageLabel = "Comenzi per pagină";
    nextPageLabel     = "pagina anterioară";
    previousPageLabel = "pagina următoare";

    getRangeLabel(page: number, pageSize: number, length: number): string {
      if (length === 0 || pageSize === 0) {
        return `0 la ${length}`;
      }
      length = Math.max(length, 0);
      const startIndex = page * pageSize;

      const endIndex = startIndex < length ?
        Math.min(startIndex + pageSize, length) :
        startIndex + pageSize;
      return `${startIndex + 1} - ${endIndex} din ${length}`;
    }
}

如果我删除此行：

{ provide: MdPaginatorIntl, useClass: mdPaginatorIntlRo }

分页符工作得很好，但它是英文的。

我错过了什么？

我认为你已经失去了＆＃39;变化＆＃39;根据文件：API reference for Angular Material paginator的财产。也许不是重写整个类，而是扩展MdPaginatorIntl：

export class mdPaginatorIntlRo extends MatPaginatorIntl

设置MdPaginatorIntl提供程序后，我得到＆＃34;无法读取属性＆＃39;订阅＆＃39;未定义＆＃34;
