angular - 我可以让我的 Angular 应用程序兼容所有版本的 IE 吗?
问题描述
我想让我的 Angular 6 应用程序与 IE 版本 7-11 兼容。我不知道这是否可能。我遵循了另一篇关于 polyfills 文件的帖子的一些建议,但没有运气。
我的 polyfils 看起来像:
/**
* 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
*/
/***************************************************************************************************
* BROWSER POLYFILLS
*/
/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';
/** IE10 and IE11 requires the following for NgClass support on SVG elements */
import 'classlist.js'; // Run `npm install --save classlist.js`.
/** IE10 and IE11 requires the following for the Reflect API. */
// import 'core-js/es6/reflect';
/** Evergreen browsers require these. **/
// Used for reflect-metadata in JIT. If you use AOT (and only Angular decorators), you can remove.
import 'core-js/es7/reflect';
/**
* Web Animations `@angular/platform-browser/animations`
* Only required if AnimationBuilder is used within the application and using IE/Edge or Safari.
* Standard animation support in Angular DOES NOT require any polyfills (as of Angular 6.0).
**/
// import 'web-animations-js'; // Run `npm install --save web-animations-js`.
/**
* By default, zone.js will patch all possible macroTask and DomEvents
* user can disable parts of macroTask/DomEvents patch by setting following flags
*/
// (window as any).__Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
// (window as any).__Zone_disable_on_property = true; // disable patch onProperty such as onclick
// (window as any).__zone_symbol__BLACK_LISTED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
/*
* in IE/Edge developer tools, the addEventListener will also be wrapped by zone.js
* with the following flag, it will bypass `zone.js` patch for IE/Edge
*/
// (window as any).__Zone_enable_cross_context_check = true;
/***************************************************************************************************
* Zone JS is required by default for Angular itself.
*/
import 'zone.js/dist/zone'; // Included with Angular CLI.
/***************************************************************************************************
* APPLICATION IMPORTS
*/
到目前为止,除了 IE 11 之外,我在所有版本的 IE 中都遇到了一堆错误。例如:
Error: Object doesn't support property or method 'bind' on the 3rd line here
var jsonpArray = window["webpackJsonp"] = window["webpackJsonp"] || [];
var oldJsonpFunction = jsonpArray.push.bind(jsonpArray);
jsonpArray.push = webpackJsonpCallback;
jsonpArray = jsonpArray.slice();
Error: Expected identifier, string or number one the resolvePromise line
var value = zone.run(delegate, undefined, isFinallyPromise && delegate !== forwardRejection && delegate !== forwardResolution ?
[] :
[parentPromiseValue]);
resolvePromise(chainPromise, true, value);
}
我不确定是否有什么我能做的,但我会很感激任何建议。如果您需要有关我的应用程序的更多信息,请告诉我。
解决方案
从 Angular 6 官方文档中的浏览器支持来看,Angular 6 只支持 IE 9-11。所以我认为我们无法在 IE < 9 中支持 Angular 6。
要支持 IE 9-11,您还可以取消注释import 'core-js/es6/reflect';
和import 'web-animations-js';
. 简单的方法就是// import
用import
polyfill.ts替换所有内容。之后,您需要使用 npm 安装一些软件包:
npm install --save classlist.js
npm install --save web-animations-js
<meta http-equiv="X-UA-Compatible" content="IE=edge">
最后,在index.html中添加元标记。
此外,如果您的代码包含更多 IE 不支持的代码,那么您必须找到 polyfill 并自己导入。
