带有 Angular CLI 8.2 的 Office Word 插件 - 出现未处理的导航错误

如何解决带有 Angular CLI 8.2 的 Office Word 插件 - 出现未处理的导航错误

我正在尝试在使用 Angular CLI 8.2 构建的 Office Word 插件中运行一个简单的应用程序。此应用程序有一个带有链接的主页。该链接应该路由到另一个组件。路由适用于 Edge 和 IE 11，但不适用于 Word 插件。在单词中加载应用程序。我看到了主页，但我在开发人员工具中看到了这个错误，但没有详细信息。当我点击链接时，它什么也没做。我认为由于以下错误，角度路由不起作用。

操作系统：Windows 10， Microsoft Word：2016 (16.0.5110)

这是我的 package.json

  }
}

tsconfig.json

我已将目标从“es2015”更新为“es5”以使其在 IE 中工作。否则它会显示一个空白页面。

app.module.ts

import { browserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { LoadComponent  } from './load/load.component';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent,LoadComponent
  ],imports: [
    browserModule,AppRoutingModule
  ],providers: [],bootstrap: [AppComponent]
})
export class AppModule { }

app.component.html

为了安全起见，我添加了带斜线和不带斜线的路线。两个链接都不起作用。它根本没有做任何事情。

<ul class="sidebar-nav nav-pills nav-stacked" id="menu">
    <li>
        <a routerLink="load" title="Load component" style="cursor: pointer;">Link 1</a>
    </li>
    <li>
        <a routerLink="/load" title="Load component" style="cursor: pointer;">Link 2</a>
    </li>
</ul>


<router-outlet></router-outlet>

load.component.html

<div> Load Component works ! </div>

app-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes,RouterModule } from '@angular/router';
import { LoadComponent } from './load/load.component';

const routes: Routes = [
  { path: 'load',component: LoadComponent }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],exports: [RouterModule]
})
export class AppRoutingModule { }

我已经尝试了所有可以在网上找到的方法，但无法解决问题。

更新

我删除了所有不必要的代码，发现添加以下代码行后，我看到导航错误：

  imports: [
    browserModule,RouterModule.forRoot(routes)  // This line
  ],

这是清单文件中的 URL。


  <DefaultSettings>
    <SourceLocation DefaultValue="http://localhost/ab/" />   
  </DefaultSettings>

解决方法

这就是我解决问题的方法..

由于开发人员工具未显示任何错误详细信息。我打开 node_modules@angular\router\bundles\router.umd.js 并搜索错误“未处理的导航错误”。在异常情况下，它在没有任何细节的情况下抛出此错误，我添加了一个代码链接以在控制台中编写整个异常。我跑完应用后，看到了err的详细信息：

调试路由器代码后，我发现“window.history.replaceState()”和“window.history.pushState()”为空。可能是 word addin 使那些为空。这是我想不通的。因为我的代码非常简单并且没有引用任何第三方 Javascript API（甚至没有 office.js）。

我在 index.html 中添加了以下代码并解决了问题：

  <script>
    window.history.replaceState = function(){};
    window.history.pushState = function(){};
  </script>
