角度6- IE11上的GET/POST问题-符号(RxSubscriber)是未定义的
提问于 2018-08-27 11:18:06
我有一个奇怪的问题，简单的GET/POST工作在IE11上的角度为6-符号(RxSubscriber)是未定义的。同样的问题发生在角5。不幸的是升级没有帮助。这段代码在Chrome和Firefox上运行得很好，但是在IE上我发现了下面的错误。更有趣的是，当ng在IE11上服务和运行时，同样的代码也能很好地工作。.NET是在ASP.NET MVC视图中继承的，如下所示。此外，填充是未注释的，因为它应该在IE上工作。应用程序是组合式的.NET WebForms/.NET MVC/Angular。有什么办法解决吗？

好吧，我发现了一个问题。问题并不像我最初想的那样与.NET WebForms/.NET MVC/角组合有关。忘了我把pace.min.js放在了角脚本之前，这是问题的根源。当我移动这个脚本后，角的问题消失了。我通过在zone.js上对IE11进行调试来跟踪它，并在IE11控制台中得到了两个相同错误的提示。它看起来像是pace.js与zone.js的冲突，因为所有的XHR(对XHR的角度重建请求/POST请求)都失败了。不知道它为什么在Chrome或Firefox中正确工作，但是如果您在角脚本之前的任何地方使用pace.js，请考虑在它们后面移动它，如下所示：
<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>页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
