我正在使用角度5。
遵循以下步骤:
将web-animations-js添加为依赖项:
npm install web-animations-js
然后在polyfils.ts中取消注释以下行
import 'web-animations-js'; // Run npm install --save web-animations-js.
polyfill.ts:
/**
* This file includes polyfills needed by Angular and is loaded before the app.
* You can add your own extra polyfills to this file.
*
* This file is divided into 2 sections:
* 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
* 2. Application imports. Files imported after ZoneJS that should be loaded before your main
* file.
*
* The current setup is for so-called "evergreen" browsers; the last versions of browsers that
* automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
* Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
*
* Learn more in https://angular.io/docs/ts/latest/guide/browser-support.html

我在IE9中遇到错误,在chrome,firefox和IE10和11中工作正常:
SCRIPT5007:预期对象
web-animations.min.js(15,23868)
引荐:Adding the polyfill with the newer, Webpack version of Angular CLI is easier:
此外,由于在IE9中不支持promise,因此我在index.html中为promise lib添加了polyfill:
<script src="https://cdn.jsdelivr.net/npm/promise-polyfill@8/dist/polyfill.min.js"></script>
答案 0 :(得分:0)
可以通过在polyfill.ts
中将此行注释掉来解决此问题:
//import 'web-animations-js'; // Run `npm install --save web-animations-js`.
但是解决上述问题后的下一个问题将是:
动画在IE 10、11中不起作用
并且在IE的控制台中将输出以下错误:
提供的动画属性“ transform”不是动画支持的CSS属性
并且此动画属性在IE 9中不起作用,因为Angular Material支持所有主要浏览器的最新两个版本:Chrome(包括Android),Firefox,Safari(包括iOS)和IE11 / Edge https://github.com/angular/material2#browser-and-screen-reader-support
问题已解决-as we still have not be able to reproduce this issue on a supported browser.
因此它只能在IE 10、11中工作
