css - 使用 Toastr，我怎样才能创建一个与默认值完全不同的 toast（我的选择是什么？）

问题描述

我正在使用 Angular 9 和 ngx-toastr

我的任务是使用 toastr 创建一组看起来与默认 toast 样式完全不同的 toast。集合中的每一个都基本相同，除了边框颜色、字体很棒的图标和消息（我可以传入）。

这是吐司模型之一：在此处输入图像描述

Toastr 有它自己的 toastr.css 样式表，我将它添加到 angular.json 中。没有它，吐司甚至都不会打开。我有自己的 toast-messages.scss 文件，其中包含实现我的模型的所有 css。我将包括它。它也被添加到 angular.json

            "styles": [
              "node_modules/@fortawesome/fontawesome-free/css/fontawesome.css",
              "node_modules/@fortawesome/fontawesome-free/css/solid.css",
              "src/styles.scss",
              "node_modules/ngx-toastr/toastr.css",
              "src/app/styles/toast-messages.scss"
            ],

我发现，除非我的 toast-messages.scss 文件中的每一行都需要一个!important才能覆盖 toastr.css 中的内容，否则你知道这很可怕。

我的问题 在我的 CSS 中不使用所有这些 !important 标签的情况下，我有哪些选择来创建这种风格的吐司。我是否在错误的位置引用了 css/scss 文件？我应该创建一个自定义吐司吗？如果是这样，是否有很好的资源？我才 2 个月进入 Angular。

toast-messages.scss 我知道我的格式很糟糕，这是反复试验

解决方案

您可以按照文档中的说明创建自定义吐司

您可以按照以下代码：

import {
  animate,
  keyframes,
  state,
  style,
  transition,
  trigger
} from '@angular/animations';
import { Component } from '@angular/core';

import { Toast, ToastrService, ToastPackage } from '../lib/public_api';

@Component({
  selector: '[pink-toast-component]',
  styles: [`
    :host {
      background-color: #FF69B4;
      position: relative;
      overflow: hidden;
      margin: 0 0 6px;
      padding: 10px 10px 10px 10px;
      width: 300px;
      border-radius: 3px 3px 3px 3px;
      color: #FFFFFF;
      pointer-events: all;
      cursor: pointer;
    }
    .btn-pink {
      -webkit-backface-visibility: hidden;
      -webkit-transform: translateZ(0);
    }
  `],
  template: `
  <div class="row" [style.display]="state.value === 'inactive' ? 'none' : ''">
    <div class="col-9">

      <div *ngIf="message && options.enableHtml" role="alert" aria-live="polite"

      transition('inactive => active', animate('400ms ease-out', keyframes([
        style({
          transform: 'translate3d(100%, 0, 0) skewX(-30deg)',

    ]),
  ],

export class PinkToast extends Toast {
  // used for demo purposes
  undoString = 'undo';

  // constructor is only necessary when not using AoT
  constructor(
    protected toastrService: ToastrService,
    public toastPackage: ToastPackage,
  ) {
    super(toastrService, toastPackage);
  }

  action(event: Event) {
    event.stopPropagation();
    this.undoString = 'undid';
    this.toastPackage.triggerAction();
    return false;
  }
}
