[转]Angular 2 / 4 / 5 not working in IE11

The latest version of angular
is only setup for evergreen browsers by default...
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.
This also includes firefox, although not mentioned.
See here for more information on browser support along with a list of suggested polyfills for specific browsers. https://angular.io/guide/browser-support#polyfill-libs
This means that you manually have to enable the correct polyfills to get Angular working in IE11 and below.
To achieve this, go into polyfills.ts
(in the src
folder by default) and just uncomment the following imports:
/***************************************************************************************************
* BROWSER POLYFILLS
*/
/** 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/set';
Note that the comment is literally in the file, so this is easy to find.
If you are still having issues, you can downgrade the target
property to es5
in tsconfig.json
as @MikeDub
suggested. What this does is change the compilation output of any es6
definitions to es5
definitions. For example, fat arrow functions (()=>{}
) will be compiled to anonymous functions (function(){}
). You can find a list of es6 supported browsers here.
For me with iexplorer 11 and Angular 2 I fixed all those above issues by doing 2 things:
in index.html add:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
in src\polyfills.ts uncomment:
/** 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';
