Notification通知提醒框

全局展示通知提醒信息。

何时使用

在系统四个角显示通知提醒信息。经常用于以下情况：

• 较为复杂的通知内容。
• 带有交互的通知，给出用户下一步的行动点。
• 系统主动推送。

import { NzNotificationModule } from 'ng-zorro-antd/notification';

代码演示

基本

最简单的用法，4.5 秒后自动关闭。

import { Component } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-basic',
  template: ` <button nz-button [nzType]="'primary'" (click)="createBasicNotification()">Open the notification box</button> `
})
export class NzDemoNotificationBasicComponent {
  constructor(private notification: NzNotificationService) {}
  createBasicNotification(): void {
    this.notification
      .blank(
        'Notification Title',
        'This is the content of the notification. This is the content of the notification. This is the content of the notification.'
      )
      .onClick.subscribe(() => {
        console.log('notification clicked!');
      });
  }
}

带有图标的通知提醒框

通知提醒框左侧有图标。

import { Component } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-with-icon',
  template: `
    <button nz-button (click)="createNotification('success')">Success</button>
    <button nz-button (click)="createNotification('info')">Info</button>
    <button nz-button (click)="createNotification('warning')">Warning</button>
    <button nz-button (click)="createNotification('error')">Error</button>
  `,
  styles: [
    `
      button {
        margin-right: 1em;
      }
    `
  ]
})
export class NzDemoNotificationWithIconComponent {
  createNotification(type: string): void {
    this.notification.create(
      type,
      'Notification Title',
      'This is the content of the notification. This is the content of the notification. This is the content of the notification.'
    );
  }
  constructor(private notification: NzNotificationService) {}
}

自定义图标

图标可以被自定义。

import { Component, TemplateRef } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-custom-icon',
  template: `
    <ng-template #template>
      <div class="ant-notification-notice-content">
        <div class="ant-notification-notice-with-icon">
          <span class="ant-notification-notice-icon"><i nz-icon nzType="smile" style="color: rgb(16, 142, 233);"></i></span>
          <div class="ant-notification-notice-message">Notification Title</div>
          <div class="ant-notification-notice-description">
            This is the content of the notification. This is the content of the notification. This is the content of the notification.
          </div>
        </div>
      </div>
    </ng-template>
    <button nz-button [nzType]="'primary'" (click)="createBasicNotification(template)">
      Open the notification box
    </button>
  `
})
export class NzDemoNotificationCustomIconComponent {
  constructor(private notification: NzNotificationService) {}
  createBasicNotification(template: TemplateRef<{}>): void {
    this.notification.template(template);
  }
}

自定义样式

使用 nzStyle 和 nzClass 来定义样式。

import { Component } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-custom-style',
  template: `
    <button nz-button [nzType]="'primary'" (click)="createBasicNotification()">Open the notification box</button>
  `
})
export class NzDemoNotificationCustomStyleComponent {
  constructor(private notification: NzNotificationService) {}
  createBasicNotification(): void {
    this.notification.blank(
      'Notification Title',
      'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
      {
        nzStyle: {
          width: '600px',
          marginLeft: '-265px'
        },
        nzClass: 'test-class'
      }
    );
  }
}

使用模板

通过模板来实现更加复杂的效果和交互。

import { Component, TemplateRef, ViewChild } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-template',
  template: `
    <button nz-button [nzType]="'primary'" (click)="ninja()">Open the notification box</button>
    <ng-template let-fruit="data">
      It's a <nz-tag [nzColor]="fruit.color">{{ fruit.name }}</nz-tag>
      <button nz-button nzSize="small">Cut It!</button>
    </ng-template>
  `,
  styles: [
    `
      button {
        margin-top: 8px;
      }
    `
  ]
})
export class NzDemoNotificationTemplateComponent {
  @ViewChild(TemplateRef, { static: false }) template?: TemplateRef<{}>;
  ninja(): void {
    const fruits = [
      { name: 'Apple', color: 'red' },
      { name: 'Orange', color: 'orange' },
      { name: 'Watermelon', color: 'green' }
    ];
    fruits.forEach(fruit => {
      this.notificationService.template(this.template!, { nzData: fruit });
    });
  }
  constructor(private notificationService: NzNotificationService) {}
}

自动关闭的延时

自定义通知框自动关闭的延时，默认4.5s，取消自动关闭只要将该值设为 0 即可。

import { Component } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-duration',
  template: `
    <button nz-button [nzType]="'primary'" (click)="createBasicNotification()">Open the notification box</button>
  `
})
export class NzDemoNotificationDurationComponent {
  createBasicNotification(): void {
    this.notification.blank(
      'Notification Title',
      'I will never close automatically. I will be close automatically. I will never close automatically.',
      { nzDuration: 0 }
    );
  }
  constructor(private notification: NzNotificationService) {}
}

自定义按钮

自定义关闭按钮的样式和文字。

import { Component, TemplateRef } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-with-btn',
  template: `
    <ng-template #template let-notification>
      <div class="ant-notification-notice-content">
        <div>
          <div class="ant-notification-notice-message">Notification Title</div>
          <div class="ant-notification-notice-description">
            A function will be be called after the notification is closed (automatically after the "duration" time of manually).
          </div>
          <span class="ant-notification-notice-btn">
            <button nz-button nzType="primary" nzSize="small" (click)="notification.close()">
              <span>Confirm</span>
            </button>
          </span>
        </div>
      </div>
    </ng-template>
    <button nz-button [nzType]="'primary'" (click)="createBasicNotification(template)">
      Open the notification box
    </button>
  `
})
export class NzDemoNotificationWithBtnComponent {
  constructor(private notification: NzNotificationService) {}
  createBasicNotification(template: TemplateRef<{}>): void {
    this.notification.template(template);
  }
}

位置

通知从右上角、右下角、左下角、左上角弹出。

import { Component } from '@angular/core';
import { NzNotificationPlacement, NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-placement',
  template: `
    <button nz-button (click)="createBasicNotification('topLeft')" nzType="primary"><i nz-icon nzType="radius-upleft"></i> topLeft</button>
    <button nz-button (click)="createBasicNotification('topRight')" nzType="primary">
      <i nz-icon nzType="radius-upright"></i> topRight
    </button>
    <nz-divider></nz-divider>
    <button nz-button (click)="createBasicNotification('bottomLeft')" nzType="primary">
      <i nz-icon nzType="radius-bottomleft"></i> bottomLeft
    </button>
    <button nz-button (click)="createBasicNotification('bottomRight')" nzType="primary">
      <i nz-icon nzType="radius-bottomright"></i> bottomRight
    </button>
  `,
  styles: [
    `
      button {
        margin-right: 1em;
      }
    `
  ]
})
export class NzDemoNotificationPlacementComponent {
  placement = 'topRight';
  createBasicNotification(position: NzNotificationPlacement): void {
    this.notification.blank(
      'Notification Title',
      'This is the content of the notification. This is the content of the notification. This is the content of the notification.',
      { nzPlacement: position }
    );
  }
  constructor(private notification: NzNotificationService) {}
}

更新消息内容

可以通过唯一的 nzKey 来更新内容。

import { Component } from '@angular/core';
import { NzNotificationService } from 'ng-zorro-antd/notification';
@Component({
  selector: 'nz-demo-notification-update',
  template: `
    <button nz-button [nzType]="'primary'" (click)="createAutoUpdatingNotifications()">
      Open the notification box
    </button>
  `
})
export class NzDemoNotificationUpdateComponent {
  constructor(private notification: NzNotificationService) {}
  createAutoUpdatingNotifications(): void {
    this.notification.blank('Notification Title', 'Description.', {
      nzKey: 'key'
    });
    setTimeout(() => {
      this.notification.blank('New Title', 'New description', {
        nzKey: 'key'
      });
    }, 1000);
  }
}

API

NzNotificationServiceservice

组件提供了一些服务方法，使用方式和参数如下：

• NzNotificationService.blank(title, content, [options]) // 不带图标的提示
• NzNotificationService.success(title, content, [options])
• NzNotificationService.error(title, content, [options])
• NzNotificationService.info(title, content, [options])
• NzNotificationService.warning(title, content, [options])

options 支持设置的参数如下：

还提供了全局销毁方法：

• NzNotificationService.remove(id) // 移除特定id的消息，当id为空时，移除所有消息（该消息id通过上述方法返回值中得到）

全局配置

可以通过 NzConfigService 进行全局配置。

NzNotificationRef

当你调用 NzNotificationService.success 或其他方法时会返回该对象。

export interface NzNotificationDataRef {
  messageId: string;
  onClose: Subject<boolean>; // 当 notification 关闭时它会派发一个事件，如果为用户手动关闭会派发 `true`
  onClick: Subject<MouseEvent>;
}
