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

ERROR TypeError: Invalid calling object

我究竟做错了什么？

速度与 zone.js v0.8.12 中的更改之间存在冲突 - 有关详细信息，请参见下文。为了解决这个问题，我确保在 zone.min.js 和其他 IE polyfills 之后加载 pace.min.js，它就像一个魅力。

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.

正如@Dovev Hefetz 所建议并在此git线程中讨论的那样，似乎可以确认脚本加载的顺序会影响这种情况下的 IE 行为。对于那些不确定如何在 Angular 主脚本之后加载 pace.min.js 的人，请按照以下简单步骤操作。

  • 确保将package.json中的 zone.js 更改为"zone.js": "~0.8.11"

或者

  • 从您的index.html中删除单个导入：

    <script src="/pace/pace.js"></script> <link href="/pace/themes/pace-theme-barber-shop.css" rel="stylesheet" />

  • 在您的angular(-cli).json中：

    1. 在样式中包含速度主题.css

    "styles": [ "src/assets/plugins/pace/pace-theme-flash.css", "src/styles.scss" ],

    1. 在脚本中包含pace.min.js

    "scripts": [ "src/assets/plugins/pace/pace.min.js" ]

  • 而已！这应该确保在 zone.js 之后加载速度

奖励： Angular 支持现代浏览器和 Internet Explorer。为了充分利用它提供的功能，您的项目需要额外的小调整来支持一些库。一个很好的起点是检查这个很棒的帖子。
