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)

error in IE9

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>

1 个答案:

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:

  1. 动画在IE 10、11中不起作用

  2. 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
