Angular2异常:TypeError el.createShadowRoot不是一个函数(Safari/Edge) [英] Angular2 Exception: TypeError el.createShadowRoot is not a function (Safari/Edge)

问题描述

我有一个angular2应用程序，可在Chrome和Firefox上很好用，但是在Safari中出现此错误:

I have an angular2 app that works great in Chrome and Firefox, but in Safari I get this error:

TypeError el.createShadowRoot不是函数

TypeError el.createShadowRoot is not a function

同样在Edge中:

对象不支持属性或方法"createShadowRoot" 在BrowserDomAdapter.prototype.createShadowRoot( http://localhost:5000/lib/angular2/bundles/angular2.dev.js:22893:7 )

Object doesn't support property or method 'createShadowRoot' at BrowserDomAdapter.prototype.createShadowRoot (http://localhost:5000/lib/angular2/bundles/angular2.dev.js:22893:7)

来自Edge的更多内容:

More from Edge:

我缺少一些垫片或聚合物吗?

Is there some shim or polymer I am missing?

推荐答案

createShadowRoot()仅在使用ViewEncapsulation.Native时才能调用.

createShadowRoot() should only be called if you use ViewEncapsulation.Native.

要么使用ViewEncapsulation.Emulated要么确保加载了polyfill(我不能指导您如何操作，因为我不使用TS工具链，仅使用Dart)

Either use ViewEncapsulation.Emulated or ensure polyfills are loaded (I can't guide you how, because I don't use the TS toolchain, only Dart)
