IE(9+)中的Angular 2+问题

Question

在启用了开发和生产环境下所有建议的 polyfills 后，Angular 2+(6) 应用程序在 IE 中无法正常工作（部署在内部网络环境中）。我知道这个问题已经被问过很多次，但它们并没有帮助。

我已经尝试了互联网上所有可能的解决方法。

IE 9+ 控制台错误：（我尝试添加兼容性视图，但这不是一个好主意）

浏览器兼容性填充也运行了所需的命令（网页动画和classlist）

/** 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.

tsconfig.json 的目标已经设置为 es5（许多互联网上的建议）。

    ],
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

Angular 版本 (ng --version)

index.html（根据许多建议添加了元标记）

<!doctype html>

如果你打开vendor.js文件，第139973个字符周围是什么？我认为你的angular.json文件中（或者其他地方包含的文件）有一个脚本可能使用了ES6语法（例如：let），因此需要找到正确的文件进行包含。你可能会遇到难以确定代码来自哪个原始脚本的问题 - sourcemaps可以帮助解决这个问题。 - Kevin Doyon

这个问题有任何更新吗？ - Sathish Kotha

我已经通过在index.html文件中添加swiper js文件并删除angular2 swiper第三方插件来解决问题。请使用此示例：Codepen链接。Swiper js链接：swiper.js，同时还需添加swiper 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>
