在IE9中使用Angular 2需要什么？

Question

在IE9中使用Angular 2需要什么？

我一直在尝试创建一个Angular 2应用程序(使用入门指南)作为模板,但虽然它在Chrome中运行得非常好,但我很难让它在IE9中运行!

基本上,应用程序在加载/运行boot/js时失败,并向开发人员控制台报告以下错误.

日志:错误:对象不支持此操作

有没有人有任何建议或建议 - 甚至更好 - 一个实际在IE9中工作的演示？

我的index.html的开头如下所示......

<head>
<title ng-bind="title">xxx</title>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no" />

更新1:通过更多测试(主要是在较新的IE浏览器中)我正在尝试同样的问题,但看到更多细节..

修复Angular2 RC4 IE9:

包含脚本:

<script src="https://npmcdn.com/angular2@2.0.0beta.17/es6/dev/src/testing/shims_for_IE.js"></script>

将路由方法更改为"#"

import { LocationStrategy, HashLocationStrategy } from '@angular/common'; ... bootstrap(AppComponent, [ ..., { provide: LocationStrategy, useClass: HashLocationStrategy } ]);

请勿使用浏览器历史记录进行导航:

window.history.back(); //BAD

所以，经过几个小时的拉扯之后，在这里与@kevinB（谢谢）进行了对话，并最终提出了一张罚单https://github.com/angular/angular/issues/6479#issuecomment-171582759

事实证明这是人为错误！

我从 cloudflare CDN 站点复制/粘贴了错误的链接，引用了 es6-sh a m.js 而不是 es6-sh i m.js

如此小的错字，却造成了严重的后果！
