Asp.net 角度6-IE11上的GET/POST问题-符号（rxSubscriber）未定义

asp.net asp.net-mvc angular internet-explorer

Asp.net 角度6-IE11上的GET/POST问题-符号（rxSubscriber）未定义,asp.net,asp.net-mvc,angular,internet-explorer,polyfills,Asp.net,Asp.net Mvc,Angular,Internet Explorer,Polyfills,我在IE11上使用Angular 6时遇到了一个奇怪的问题-符号（rxSubscriber）未定义。同样的问题发生在Angular 5上。不幸的是，升级没有帮助。 这段代码在Chrome和Firefox上运行良好，但在IE上我得到了如下错误。更有趣的是，当ng服务并运行在IE11上时，同样的代码也能很好地工作。Angular在ASP.NETMVC视图中继承，如下所示。另外，polyfill是未注释的，在IE上应该是这样的。应用程序是combo.NET WebForms/.NET MVC/Angu

好的，我发现了一个问题。这个问题和我最初认为的.NETWebForms/.NETMVC/Angular组合无关。忘记了我将pace.min.js放在Angular脚本之前，这是问题的根源。当我在问题解决后移动这个脚本时。我通过在IE11上调试zone.js来跟踪它，并得到了IE11控制台中出现2个相同错误的提示。看起来pace.js与zone.js冲突，因为所有XHR（对XHR的GET/POST请求）都失败了。不知道为什么它在Chrome或Firefox中能正常工作，但是如果你在PACE.JS的任何地方使用你的角脚本考虑在他们后面移动它，像这样：

<script type="text/javascript" src="@virtualPathDirectory/Angular-Test/dist/Angular-Test/runtime.js"></script>
<script type="text/javascript" src="@virtualPathDirectory/Angular-Test/dist/Angular-Test/polyfills.js"></script>
<script type="text/javascript" src="@virtualPathDirectory/Angular-Test/dist/Angular-Test/main.js"></script>
<script type="text/javascript" src="@virtualPathDirectory/Angular-Test/dist/Angular-Test/vendor.js"></script>
<script type="text/javascript" src="@virtualPathDirectory/bootstrap/js/plugins/pace/pace.min.js"></script>
在最后一个小时里，我在Symbol（rxSubscriber）上猛击了我的头，然后我来到这里，几乎看到了我的整个设置，并且遇到了相同的问题。@DamonDrake很高兴我能提供帮助：）Angular 7也出现了这个问题。下面的答案修正了它，就像它修正角6一样。
