Angular 2 Universal ng2-bootstrap无法正常运行Safari

我使用Angular 2和ng2-bootstrap创建的网站以及使用Webpack和Universal提供服务的网站一直在Chrome上工作，但在Safari或Microsoft Edge上无效。

目前Safari是最重要的。

在开发者控制台中，我收到以下错误：

这对我没什么帮助，因为我无法找出它试图分配什么的只读属性。

我将在此处发布我的进展，因为我发现了更多。

更新

我已更新到最新的Angular 2 2.1.0版本，但仍然没有运气。

我还读了另一个项目，有人删除了“使用严格”;从项目来看，这至少加载了页面而没有任何错误。但是，当我尝试点击链接时，错误又回来了。

更新

我终于找到导致错误的实际行：

BrowserDomAdapter.prototype.setProperty = function(el, name, value) {
   el[name] = value
};

在设置属性之前是否有可能找出属性是否只读？

更新

我想我修复了一个错误。在我的模板中的一个组件中，我分配了readonly的样式属性。

所以我没有<div [style]="getStyle()">代替<div [attr.style]="getStyle()">来阻止TypeError的提升。

但是，现在我又出现了另一个错误：

原来它在Angular的common / bundles / common.umd.js中，但它在Safari中是未定义的。有什么想法吗？

1 个答案:

答案 0 :(得分：1)

所以最终修复是将Intl包含在项目中：

npm install intl --save

在您的主要模块中：

import intl
import 'intl/locale-data/jsonp/nb';

TypeError是由于尝试将某些内容分配给（readonly）样式属性。请参阅上面的更新。
