Question

我在angular2应用程序中加载模板时遇到问题。

system.config.js：

(function (global) {
    System.config({
        paths: {
            // paths serve as alias
            'npm:': '/libs/'
        },
        // map tells the System loader where to look for things
        map: {
            // our app is within the app folder
            app: '/Scripts',
            // angular bundles
            '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
            '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
            '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
            '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
            '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
            '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
            '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
            '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
            '@angular/material': 'npm:@angular/material/bundles/material.umd.js',
            // other libraries
            'rxjs': 'npm:rxjs',
            'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
        },
        // packages tells the System loader how to load when no filename and/or no extension
        packages: {
            app: {
                main: './main.js',
                defaultExtension: 'js'
            },
            rxjs: {
                defaultExtension: 'js'
            },
            'angular2-in-memory-web-api': {
                main: './index.js',
                defaultExtension: 'js'
            }
        }
    });
})(this);

boot.ts

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

import { AccountsAppComponent } from './Accounts/app';
import { LoginComponent } from './Accounts/Login/Login.component';
import { RegisterComponent } from './Accounts/Register/Register.component';

@NgModule({
    imports: [
        BrowserModule
    ],
    declarations: [
        AccountsAppComponent,
        LoginComponent,
        RegisterComponent
        ],
    bootstrap: [AccountsAppComponent]
})
export class AppModule { }

app.ts：

import { Component } from '@angular/core';
import { LoginComponent } from './Login/Login.component';
import { RegisterComponent } from './Register/Register.component';

@Component({
    selector: 'my-app',
    template: `<login-form></login-form> <register-form></register-form>`
})
export class AccountsAppComponent {
    title = 'ASP.NET MVC 5 with Angular 2';
    skills = ['MVC 5', 'Angular 2', 'TypeScript', 'Visual Studio 2015'];
    myskills = this.skills[1];
}

Register.component.ts：

import { Component, OnInit } from '@angular/core';

@Component({
    selector: 'register-form',
    templateUrl: './Accounts/Register/Register.component.html'
})
export class RegisterComponent implements OnInit {
    constructor() { }

    ngOnInit() { }
}

我尝试过不同的路径，例如：

'./Accounts/Register/Register.component.html'
'./Register/Register.component.html'
'./Register.component.html'

如果我使用template:代码，我可以成功加载我的HTML代码，但是如果我使用templateUrl:它无法正常工作。起初我觉得路径有问题，但是当我尝试不同的路径时，我意识到这是另一回事。我想知道是什么导致了这些问题。

将路径更改为相对于文件的位置。很可能模板的文件名或其位置不匹配，但正确的路径应为：

<root>/Accounts/Register/Accounts/Register/Register.component.html

假设您的项目结构是：

'./Register.component.html'

无法在mvc 5中加载angular2 templateUrl
