IE(9+) 中的 Angular 2+ 问题

Question

在为开发和生产环境(部署在Intranet 环境中)启用所有建议的 polyfill 后，Angular 2+(6) 应用程序无法在 IE 中运行。我知道这个问题已被问过很多次，但它们没有帮助。

我已经完成了互联网上所有可能的工作。

IE 9+ 控制台错误:(我也尝试添加兼容性 View ，尽管这不是一个好主意)

BROWSER POLYFILLS 也运行了所需的命令(网络动画和类列表)

/** 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.

Angular 版本(ng --version)

index.html(根据许多人的建议添加元标记)

<!doctype html>

我已通过在 index.html 文件中添加 swiper js 文件并删除 angular2 swiper 第三方插件来解决此问题，

使用这个例子:Codepen link

Swiper js 链接:swiper.js并添加滑动器 css。

import { Component, OnInit, AfterViewInit } from '@angular/core';

declare var $, Swiper: any;

@Component({
  selector: 'app-edit-view',
  templateUrl: './swiper.component.html',
  styleUrls: ['./swiper.component.css']

})
   export class SwiperDemo implements OnInit, AfterViewInit{
   ngOnInit(){
   }
    ngAfterViewInit(){
        $(document).ready(function() {
              new Swiper('.swiper-container', {
                slidesPerView: 4,
                spaceBetween: 10,
                slidesPerGroup: 1,
                observer: true,
                observeParents: true,
                loop: false,
                loopFillGroupWithBlank: false,
                pagination: { el: '.swiper-pagination', clickable: true },
                navigation: {
                  nextEl: '.swiper-button-next',
                  prevEl: '.swiper-button-prev'
                }
              });
          });
      }
   }

HTML:

 <div class="container">   
    <!-- Slider main container -->
    <div class="swiper-container">
        <!-- Additional required wrapper -->
        <div class="swiper-wrapper">
            <div class="swiper-slide">Slide 1</div>
            <div class="swiper-slide">Slide 2</div>
            <div class="swiper-slide">Slide 3</div>
            <div class="swiper-slide">Slide 4</div>
            <div class="swiper-slide">Slide 5</div>
            <div class="swiper-slide">Slide 6</div>
            <div class="swiper-slide">Slide 7</div>
            <div class="swiper-slide">Slide 8</div>
            <div class="swiper-slide">Slide 9</div>
            <div class="swiper-slide">Slide 10</div>
        </div>

        <!-- If we need navigation buttons -->
        <div class="swiper-button-prev"></div>
        <div class="swiper-button-next"></div>
    </div>
</div>
