我目前正在所有可能的浏览器中测试我的应用程序,并且我看到角度动画在Safari iOS 9.3中的行为不如预期.下班后
和小时试图解决它我来寻求帮助.提前致谢.

我的代码是：
的package.json
"dependencies": {
"@angular/animations": "^4.3.2","@angular/cdk": "^2.0.0-beta.8","@angular/common": "^4.0.0","@angular/compiler": "^4.0.0","@angular/core": "^4.0.0","@angular/forms": "^4.0.0","@angular/http": "^4.0.0","@angular/material": "^2.0.0-beta.8","@angular/platform-browser": "^4.0.0","@angular/platform-browser-dynamic": "^4.0.0","@angular/router": "^4.0.0","@ngx-Meta/core": "^0.4.0-rc.2","@ngx-translate/core": "^7.1.0","@ngx-translate/http-loader": "^1.0.1","angular2-moment": "^1.6.0","core-js": "^2.4.1","express": "^4.15.4","lodash": "^4.17.4","ng2-pdf-viewer": "^1.1.1","ng2-translate": "^5.0.0","rxjs": "^5.4.1","web-animations-js": "^2.3.1","zone.js": "^0.8.14"
},
landing.component.ts
import { Component,HostBinding,ChangeDetectionStrategy } from '@angular/core';
import { stateTransition } from '../routing.animations';
@Component({
selector: 'cp-landing',templateUrl: './landing.component.html',styleUrls: ['./landing.component.css'],changeDetection: ChangeDetectionStrategy.OnPush,animations: [ stateTransition() ]
})
export class LandingComponent {
@HostBinding('@stateTransition') '';
}
routing.animations.ts
import { trigger,state,animate,style,transition } from '@angular/animations';
export function stateTransition() {
return trigger('stateTransition',[
state('void',style({
transform: 'translateY(50%)',opacity: 0
})),state('*',style({
transform: 'translateY(0%)',opacity: 1
})),// enter animation
transition('void => *',animate('.5s 500ms')),// exit animation
transition('* => void',animate('.5s'))
]);
}
我试着想出一个小提琴,但我无法重现错误.
我相信网络动画API需要Safari上的polyfill.并且默认情况下不启用.您只需要安装polyfill,然后在app的/ src文件夹中的polyfills.ts文件中添加一行或两行.
见：How to add Web Animations API polyfill to an Angular 2 project created with Angular CLI
(复制下面的最佳答案)
使用较新的Webpack版Angular CLI添加polyfill更容易：
安装时
npm install web-animations-js --save
添加到polyfills.ts：
require('web-animations-js/web-animations.min');
如果我这样做,它也有效
import 'web-animations-js/web-animations.min';
