Javascript 角度应用程序与Internet Explorer的兼容性

我有一个具有选择地图功能的角度应用程序，用户可以在地图上选择货物的交付点

问题是，这在IE中不起作用-地图打开，但交付点未加载。 此外，如果您增加或减少贴图，它只是冻结

我尝试从polyfills.ts中取消对数据的注释，但没有任何帮助。现在有以下代码：

/**
 * 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/guide/browser-support
 */

/***************************************************************************************************
 * BROWSER POLYFILLS
 */

/** IE10 and IE11 requires the following for NgClass support on SVG elements */
// import 'classlist.js';  // Run `npm install --save classlist.js`.
import 'classlist.js';
/**
 * 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
 * because those flags need to be set before `zone.js` being loaded, and webpack
 * will put import in the top of bundle, so user need to create a separate file
 * in this directory (for example: zone-flags.ts), and put the following flags
 * into that file, and then add the following code before importing zone.js.
 * import './zone-flags.ts';
 *
 * The flags allowed in zone-flags.ts are listed here.
 *
 * The following flags will work for all browsers.
 *
 * (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__UNPATCHED_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.

以下是控制台的错误输出：

---

我可以看到您遇到了一个错误对象不支持属性或方法“includes”

出现此错误是因为IE浏览器不支持方法和方法

我建议您在polyfill.ts文件中添加以下polyfill

import 'core-js/es7/array';

它可能会帮助您修复此错误

我假设您正在使用IE 11浏览器，请确认，并告知您正在使用的Angular应用程序的版本。我不确定你在angular应用程序中使用的是哪种地图。我建议你提供更多的信息。如果可能的话，请尝试分享一个示例代码，它可以帮助我们更好地理解这个问题。我建议您检查浏览器的控制台，如果有任何错误或警告，请通知我们。谢谢你的理解。是的，IE版本是11。Angular版本是9.0.7至于代码，这里是所有使用的代码：在问题的描述中，添加了来自ConsoleEyes的错误输出，它真的帮助了我！地图可以工作，甚至可以显示我需要的物品。但是单击任何项目，都不会发生任何事情，控制台中会出现一个新错误：1。对象（23278,23）2不支持该命令。无法获取值未定义或为NULL（23278,23）的链接的“getClusters”属性。。。上面我附上了一个截图什么是在线（23278,23）。有没有办法避免这个错误？我试图搜索错误，但没有得到任何有用的信息。我建议您查看该地图库的文档，看看它是否与IE浏览器兼容。您也可以尝试在此处共享文档的链接。我可以尝试检查IE浏览器是否需要更改。出于测试目的，还可以尝试添加导入“core js/es7/map”；看看有没有什么不同。
