如何在 Angular 6+ 中的 mat-paginator 中更改 itemsPerPageLabel [英] How To Change itemsPerPageLabel in mat-paginator in Angular 6+

问题描述

我将 Angular 6.0.3 与 Angular Material 7.1.0 一起使用，我的分页器位于一个单独的组件中(不是 app.component).到目前为止我尝试过的:

I am using Angular 6.0.3 with Angular Material 7.1.0, I have my paginator in a separate component (that is not the app.component). What I have tried so far:

创建名为 myPagniator.ts 的单独 ts 文件:

Created separate ts file called myPagniator.ts:

import {MatPaginatorIntl} from '@angular/material';

export class MyPaginatorLabel extends MatPaginatorIntl {

  itemsPerPageLabel = 'custome_label_name'; // customize item per page label

  constructor() {
    super();
  }
}

在我的 app.module.ts 中:我从 Angular Material 中导入了 MatPaginatorModule、MatPaginatorIntl.在 app.module.ts 的 providers 数组中，我放入了 MyPaginatorLabel 和 MatPaginatorIntl.

In my app.module.ts : I imported both MatPaginatorModule, MatPaginatorIntl from Angular Material. Inside providers array of app.module.ts, I put in MyPaginatorLabel and MatPaginatorIntl.

在使用 Angular MatPaginator 的组件中，我扩展了 MyPaginatorLabel 类并让它的构造函数调用 super() 方法，在所有这些之后它仍然显示默认文本itemsPerPage"

In the component which is using Angular MatPaginator, I extends MyPaginatorLabel class and have its constructor calls super() method, still it displays default text "itemsPerPage" after all this

我在这里做错了什么??有人能给我一点提示吗?

What have I done wrong here ?? Can someone give me a bit of hint ?

推荐答案

创建一个新的 TypeScript 文件并添加一个导出的函数并返回一个 MatPaginatorIntl 对象.

Create a new TypeScript file and add a function that is exported and returns a MatPaginatorIntl object.

要修改显示的标签和文本，请创建 MatPaginatorIntl 的新实例并将其包含在自定义提供程序中 - Angular Material - Paginator > API

To modify the labels and text displayed, create a new instance of MatPaginatorIntl and include it in a custom provider - Angular Material - Paginator > API

CustomPaginatorConfiguration.ts

import { MatPaginatorIntl } from '@angular/material';

export function CustomPaginator() {
  const customPaginatorIntl = new MatPaginatorIntl();

  customPaginatorIntl.itemsPerPageLabel = 'Custom_Label:';

  return customPaginatorIntl;
}

然后将其添加到app.module.ts:

import { MatPaginatorIntl } from '@angular/material';
import { CustomPaginator } from './app/CustomPaginatorConfiguration';

@NgModule({
  // ...
  providers: [
    { provide: MatPaginatorIntl, useValue: CustomPaginator() }
  ]
})

您还可以为特定组件设置设置，例如:

You can also set the setting for a particular component like:

import { CustomPaginator } from './CustomPaginator';
import { MatPaginatorIntl } from '@angular/material';
/**
 * @title Paginator
 */
@Component({
  selector: 'your_component',
  templateUrl: 'your_component.html',
  providers: [
    { provide: MatPaginatorIntl, useValue: CustomPaginator() }  // Here
  ]
})
