【问题描述】:
我有一个混合 angular-cli,大致遵循 Victor Savkin 的Lazy Loaded AngularJS guide。 AngularJS 在 LazyLoaded Angular 模块的构造函数中被引导。我的应用程序和指南之间的主要区别在于我试图将 <ui-view> 指令包装在一些 Angular 组件中。由于我的布局结构,<ui-view> 元素在 AngularJS 启动时将不可用,并且可以随时添加或删除。
import { Component, Directive, ElementRef, Injector } from '@angular/core';
import { UpgradeComponent } from '@angular/upgrade/static';
import * as angular from 'angular';
@Component({
template: `
<layout-wrapper>
<my-toolbar></my-toolbar>
<layout-contents>
<ng2-ui-view>
<h3 class="text-center">AngularJS page not loaded</h3>
</ng2-ui-view>
</layout-contents>
</layout-wrapper>
`,
})
export class LegacyOutputComponent { }
@Directive({selector: 'ng2-ui-view'})
export class UpgradedUiViewComponent extends UpgradeComponent {
constructor(ref: ElementRef, inj: Injector) {
super('uiViewWrapper', ref, inj);
}
}
export const routerPatchModule = 'arcs.router.patch';
// We need to define a wrapper for ui-view because we can only upgrade
// components with only one definition. uiView cannot be automatically
// upgraded because its definition is too complex
angular.module(routerPatchModule, ['ui.router'])
.component('uiViewWrapper', { template: '<ui-view></ui-view>'})
当我运行代码时,会抛出 Error: No provider for $scope! 错误。检查堆栈跟踪我可以看到它是在UpgradeComponent 超类中抛出的。注入器尝试获取$scope 和
