Angular 2/4如何设置角度材质设计小吃栏 [英] Angular 2/4 How to style angular material design snackbar

问题描述

我是Angular2/4和angular打字稿的新手.我想为棱角材质设计 snackbar 设置样式，例如将背景颜色从黑色和字体颜色更改为其他颜色.
我该如何设计小吃店"的样式?

I am new to Angular2/4 and angular typescript. I want to style the angular material design snackbar for example change the background color from black and font color to something else.
How do i go about styleing the "snackbar" ?

我在服务/核心中有材料设计小吃栏，为了使它可用，我根据需要在每个组件中调用它.

I have the material design snackbar in the service/core and to make it available i call it in every component as needed.

如何在Angular 2/4中为Angular 2材质设计"snackbar"设置样式?我已在下面添加了代码段:

How can I style the Angular 2 material design "snackbar"in Angular 2/4? I have included the code snippet below:

服务/核心

import { Injectable, Inject } from '@angular/core';
import { Observable } from 'rxjs/Observable'
import { DOCUMENT } from'@angular/platform-browser'; 
import { MdDialog, MdDialogRef } from '@angular/material'; 
import { MdDialogConfig, ComponentType } from '@angular/material'; 
import {MdSnackBar} from '@angular/material';

constructor(
    public dialog: MdDialog,
    public snackBar: MdSnackBar,
    @Inject(DOCUMENT) public doc: any   ) {
      dialog.afterOpen.subscribe((ref: MdDialogRef<any>) => {
        if (!doc.body.classList.contains('no-scroll')) {
        doc.body.classList.add('no-scroll');
        }
      });
      dialog.afterAllClosed.subscribe(() => {
        doc.body.classList.remove('no-scroll');
      });        }

   openSnackBar(message: string, action?: string) {
    this.snackBar.open(message, action, {
      duration: 4000,
    });   }

wiz.components.ts ....

 saveData(): void {
    this.advisorClientModel.currentStep = this.currentStep;
    this.advisorClientModel.clientId = this.faService.getClientId();
    this.advisorClientModel.isMaxAmount = this.isMaximumAmount;
    this.advisorClientModel.desiredLoanAmount = this.loanAmount;
    this.advisorClientModel.maxLoanAmount = this.eligibleSelected.advanceAmount;
    this.advisorClientModel.pledgedAccounts = this.getPledgedAccountsArray();
    this.advisorClientModel.pledgedMarketValue = this.getPledgedMarkeValue();

    this.faService.updateAdvisorClient( this.advisorClientModel )
      .subscribe(
        successModel => {
          this.coreService.openSnackBar("Your Data Has been Saved");
          this.navigateTo("fa/wiz" + (this.currentStep + 1));
        },
        error => {
          this.onError(error);
        }
      );
  }

推荐答案

md-snackbar 提供了提供自定义 config 的服务. config 的一个属性是 extraClasses ，它允许将CSS类添加到小吃店容器(

md-snackbar provides a service to provide custom config. One the properties of config is extraClasses that allows to add CSS classes to the snack bar container (doc).

extraClasses 可以与 :: ng-deep 一起使用，以覆盖默认的CSS类.这是一个示例:

extraClasses can be used with ::ng-deep to override the default CSS classes. Here's an example:

component.ts:

需要在组件中执行以下 import :

Requires following import in the component:

import {MdSnackBar, MdSnackBarConfig} from '@angular/material';

(提供自定义配置)

openSnackBar(message: string, action?: string) {
  let config = new MdSnackBarConfig();
  config.extraClasses = ['custom-class'];
  this.snackBar.open(message, action ? 'Action Label' : undefined, config);
}

component.css:

::ng-deep snack-bar-container.custom-class {
  background: yellow;
}

::ng-deep .custom-class .mat-simple-snackbar {
  color: green;
}

如果您想尝试，这是一个柱塞演示.

Here's a Plunker demo if you would like to try.

2018年11月更新:Angular 6 +

语法有所变化， md-前缀被替换为 mat-，而 extraClasses 被替换为 panelClass .该功能总体上是相同的:

The syntax has changed a bit, with the md- prefix being replaced mat- and extraClasses was replaced with panelClass. The function is overall the same though:

const config = new MatSnackBarConfig();
config.panelClass = ['custom-class'];
...

和导入:

import { MatSnackBar, MatSnackBarConfig } from '@angular/material';
