[英]RouterConfiguration and Router undefined in aurelia
我对Aurelia非常陌生,只是尝试将导航应用于我的项目。尽管我导入了aurelia-router,但仍然说RouterConfiguration和Router在构造函数中未定义
import {Todo} from './ToDo/todo';
import {RouterConfiguration, Router} from 'aurelia-router';
export class App {
heading = "Todos";
todos: Todo[] = [];
todoDescription = '';
router :any;
list: any[];
constructor(RouterConfiguration: RouterConfiguration, Router: Router) {
this.todos = [];
this.configureRouter(RouterConfiguration, Router);
//console.log("klist", this.list);
}
//config.map() adds route(s) to the router. Although only route, name,
//moduleId, href and nav are shown above there are other properties that can be included in a route.
//The class name for each route is
configureRouter(config: RouterConfiguration, router: Router): void {
this.router = router;
config.title = 'Aurelia';
config.map([
{ route: '', name: 'home', moduleId: 'home/home', nav: true, title: 'Home' },
{ route: 'users', name: 'users', moduleId: './Friends/Friends', nav: true },
//{ route: 'users/:id/detail', name: 'userDetail', moduleId: 'users/detail' },
//{ route: 'files/*path', name: 'files', moduleId: 'files/index', href: '#files', nav: 0 }
]);
}
addTodo() {
if (this.todoDescription) {
this.todos.push(new Todo(this.todoDescription));
// this.todoDescription = '';
}
}
}
按照约定,Aurelia在加载(App)的初始类中查找configureRouter()函数并执行它。 这意味着,您不必在构造函数中注入任何内容。
看来您只是添加了太多。 我认为修复样本似乎就像删除一些内容一样容易,例如:
import { Todo } from './ToDo/todo';
import { RouterConfiguration, Router } from 'aurelia-router';
export class App {
heading = "Todos";
todos: Todo[] = [];
todoDescription = '';
list: any[];
constructor() {
// note: removed routing here entirely (you don't need it)
// also, you've already declared this.todos above, so no need to do it here again
}
configureRouter(config : RouterConfiguration, router : Router): void {
this.router = router;
config.title = 'Aurelia';
config.map([
{ route: '', name: 'home', moduleId: 'home/home', nav: true, title: 'Home' },
{ route: 'users', name: 'users', moduleId: './Friends/Friends', nav: true }
]);
}
addTodo() {
// removed this for brevity
}
}
这样可以解决您在Router和RouteConfiguration上的“未定义”错误。 另外,请不要忘记将<router-view>
到您的html模板中。 否则,您将没有任何错误,但是视图也不会显示:
<template>
<div class="content">
<router-view></router-view>
</div>
</template>
可以在Aurelia Docs-Routing中找到有关此问题的出色文档 。
