【中文标题】Angular 应用程序与 Internet Explorer 的兼容性【英文标题】:Angular application compatibility with the Internet Explorer 【发布时间】:2020-09-27 10:59:27 【问题描述】:我有一个 Angular 应用程序,它具有选择地图的功能,用户可以在该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,但未加载交货点。 此外,如果您增加或减少地图,它只会冻结。
我尝试取消注释来自 polyfills.ts 的数据,但这没有帮助。现在有如下代码:
/**
* 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.
/***************************************************************************************************
* APPLICATION IMPORTS

这是控制台的错误输出: console output
Error:Command not supported by object(23278,23)
【问题讨论】:
我假设您使用的是 IE 11 浏览器,请确认并告知我们您使用的 Angular 应用程序的版本。我不确定您在 Angular 应用程序中使用的是哪种地图。我建议您提供更多有关它的信息。如果可能的话,请尝试分享一个示例代码,以帮助我们更好地理解问题。我建议你检查浏览器的控制台,如果有任何错误或警告,请通知我们。感谢您的理解。 是的,IE版本是11,Angular版本是9.0.7至于代码,这里是所有用到的代码:github.com/AlexeyKokoryshkin/Angular-map.git 在问题描述中,添加了控制台的错误输出 【参考方案1】:我可以看到您收到错误对象不支持属性或方法“包含”
您收到此错误是因为 IE 浏览器不支持 String.prototype.includes() 方法和 Array.prototype.includes() 方法。
我建议你在 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。
参考:
Object doesn't support property or method 'includes'
【讨论】:
是的,它真的帮助了我!地图有效,它甚至显示我需要的项目。但是通过单击任何项目,什么都没有发生,并且控制台中出现一个新错误: 1. 该命令不受对象 (23278,23) 支持 2. 无法获取其链接的“getClusters”属性值未定义或为 NULL (23278,23) ... 上面我附上了在线 (23278,23) 的屏幕截图。有没有办法避免这个错误?? 我尝试搜索错误但没有得到任何有用的信息。我建议你查看那个地图库的文档,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。我可以尝试检查是否需要为 IE 浏览器更改任何内容。出于测试目的,也尝试添加 import 'core-js/es7/map';看看有没有区别。以上是关于Angular 应用程序与 Internet Explorer 的兼容性的主要内容,如果未能解决你的问题,请参考以下文章
