Angular2 Final在IE11下不起作用

Question

It worked for some time and after that stopped. Probably, I imported some component or did something. It works on Firefox, Chrome, Edge, but not on IE11.

The error I get is from the Angular2 core library.

It says

SCRIPT5007: Unable to get property 'apply' of undefined or null reference

and points to this function

            function combine(options) {
                return (_a = ((Object))).assign.apply(_a, [{}].concat(options));
                var _a;
            }               

from angular intl.ts file https://github.com/angular/angular/blob/master/modules/@angular/common/src/pipes/intl.ts

How I can fix this and make it work on IE?

index.html中的Babel脚本可能会帮助您：

 <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.6.15/browser-polyfill.min.js"></script> 

Answer 2

While using angular2 CLI 2.4.* the above issue will occur in IE.

To resolve this issue make sure that you have imported the items which is need for polyfills in polyfills.ts file using angular CLI

/** 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';

Its working for me.
