Angular 2的IE错误
我需要有关此IE错误的帮助，我认为这与我的HTML页面上的绑定问题有关。 我正在使用IE 11和Angular 2.它在Chrome和Firefox上没有错误，但是我收到了一个错误 仅限IE 11。我无法追踪确切错误在我的页面上的位置，但我知道它位于我的HTML页面上，因为这部分错误。
在View_EdataReportingComponent0.prototype.detectChangesInternal（功能代码：2933：5）
这是IE中控制台的屏幕截图，显示错误。
这是我的HTML页面......

在IE中出现此类错误是完全正常的。它根本不支持所有ES6，然后你需要在IE中添加一些丢失的库 转到 src / polyfills.ts 并将其内容替换为以下内容：
/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/client/shim';
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`.
/** Evergreen browsers require these. **/
import 'core-js/es6/reflect';
import 'core-js/es7/reflect';
/**
* Required to support Web Animations `@angular/animation`.
* Needed for: All but Chrome, Firefox and Opera. http://caniuse.com/#feat=web-animation
**/
import 'web-animations-js'; // Run `npm install --save web-animations-js`.
* Zone JS is required by Angular itself.
*/
import 'zone.js/dist/zone'; // Included with Angular CLI.
运行以下命令：
- npm install --save classlist.js
- npm install --save web-animations-js
