标签： angular flip

我一直在我的项目中使用纯css翻转卡，但这个解决方案不合适。点击一个按钮，有人可以在角度2翻转吗？我在angularjs https://codepen.io/Zbeyer/pen/oXQrZg

中找到了一个 
    <div ng-app="cardFlipper" ng-controller="AppController">    
    <h1>Card Flipping AngularJS</h1>
    <div class="flip-container">
        <div class="flipper" ng-click="flipCard()" ng-class="{'flipToFront':isCardRevealed, 'flipToBack':!isCardRevealed}">
            <div class="back" ng-class="{'face-hidden':hideBackFace}">
            </div>
            <div class="front" ng-class="{'face-hidden':!hideBackFace}">
                <h1>{{currentCard.title | uppercase}}</h1>
                <p ng-if="currentCard.icon">{{currentCard.icon}}</p>
                <br ng-if="currentCard.icon" />

有人可以把它变成angular2或实现不同的东西吗？

此演示使用Angular中的动画

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

@Component({
  selector: 'app-root',
  template: `
    <div class="tp-wrapper">
      <div class="tp-box" (click)="toggleFlip()" [@flipState]="flip">
        <div class="tp-box__side tp-box__front">Front
        </div>
        <div class="tp-box__side tp-box__back">Back
        </div>
      </div>
    </div>
  `,
  styles: [
    `
    .tp-wrapper {
      perspective: 800px;
    }

    .tp-box {
      position: relative;
      width: 200px;
      height: 100px;
      margin: 3rem auto;
      transform-style: preserve-3d;
      transition: transform 1s;
    }
    .tp-box__side {
      width: 100%;
      height: 100%;
      position: absolute;
      backface-visibility: hidden;
      color: #fff;
      text-align: center;
      line-height: 100px;
      font-size: 24px;
      font-weight: 700;
      cursor: pointer;
      user-select: none;
    }
    .tp-box__front {
      background: #f30d36;
    }
    .tp-box__back {
      background: #23262d;
      transform: rotateY(179.9deg);
    }

    `
  ],
  animations: [
    trigger('flipState', [
      state('active', style({
        transform: 'rotateY(179.9deg)'
      })),
      state('inactive', style({
        transform: 'rotateY(0)'
      })),
      transition('active => inactive', animate('500ms ease-out')),
      transition('inactive => active', animate('500ms ease-in'))
    ])  
  ]
})
export class AppComponent {

  flip: string = 'inactive';
  constructor() {}

  toggleFlip() {
    this.flip = (this.flip == 'inactive') ? 'active' : 'inactive';
  }

}

这在Chrome中效果很好，但在Safari / Firefox / Opera中，当正面可见时，翻转的内容显示（反向），反之亦然，但您只需添加浏览器特定的背面 - 可见性样式。

所以替换这个：

 backface-visibility: hidden;

用这个：

-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
-o-backface-visibility: hidden;
backface-visibility: hidden;

然后它会在所有浏览器中正确显示。
