Question

我使用angular开发了应用程序。它可以在chrome和Firefox中完美呈现。但是，当我在ie-11中运行它时，我面临许多问题。

我通过在polyfills.ts中添加polyfill解决了许多问题。我仍然面临其他一些问题。请查看下面的屏幕截图。

这是我的保鲜纸，

/** 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';

// import 'whatwg-fetch';

/** 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
 */

请帮助我解决此问题。谢谢...

Answer 1

对于此问题，请确保已在# vhdl_sources.txt containing VHDL_SOURCES # vhdl_sources.txt.full containing VHDL_SOURCES plus generated filelist.txt content vhdl_sources.txt.full: $(BUILD_PWD)/filelist.txt vhdl_sources.txt cat $^ > $@中启用所有必需的导入，并且此文件已连接到polyfills.ts

并将以下内容添加到文件中：

angular.json

Answer 2

将以下内容添加到polyfills.ts

import 'core-js/es7/object';
import 'core-js/es7/array';

Answer 3

这是IE浏览器问题，您可以通过以下链接https://github.com/angular/zone.js/issues/1001进行修复对于core-js / es7 / array，您需要使用“ core-js”：“〜2.5.0”

Angular应用未在IE 11中渲染并提供了SecurityError和SyntaxError
