Pace.js在IE中不工作11

问题描述：

我有一个angular-cli项目。我也增加了步伐。我将它添加到index.html <script src="assets/lib/pace/pace.min.js"></script>的标题中。它在Chrome中正常工作，但在IE-11中出现以下错误：Pace.js在IE中不工作11

我在做什么错？

谢谢你张贴了这个问题 - 我也有过这样的错误，但在升级我的角的应用程序后，对我的生活无法弄清楚哪里它来自于。 –

答

节奏与zone.js v0.8.12中的变化之间存在冲突 - 请参阅下面的细节。为了解决这个问题，我确保在zone.min.js和其他IE浏览器的polyfills之后加载pace.min.js，它的功能就像一个魅力一样。

https://github.com/HubSpot/pace/issues/399

In the newest version of zone.js (0.8.12) using pace with it causes all XMLHttpRequests to fail with the error message: 

TypeError: Unable to get property 'apply' of undefined or null reference 
Please see my issue for more information. If I get time I'll try and fix the issue inside pace itself but I've already spent the good part of 3-4 hours trying to debug this issue so we'll see..

https://github.com/angular/zone.js/issues/816

After updating zone.js to the latest version (0.8.12) we started getting errors when loading an Angular page with angular/http calls in Internet Explorer 11 (works fine in Chrome). The request never initiates and there are a few errors in the console: 

Unhandled Promise rejection: Unable to get property 'apply' of undefined or null reference ; Zone: <root> ; Task: Promise.then ; Value: TypeError: Unable to get property 'apply' of undefined or null reference TypeError: Unable to get property 'apply' of undefined or null reference

After digging around a bit, it looks like a very new bit of code could be causing this, introduced in PR #800 

The exact line of failure is below, where oriAddListener is undefined, causing the above error : 

oriAddListener.apply(data.target, ['readystatechange', newListener]); // line 110 
Rolling zone.js back to 0.8.11 which was before that PR fixes the issue and works as expected.
