错误:未捕获(承诺):无法加载login.component.html [英] Error: Uncaught (in promise): Failed to load login.component.html
问题描述
我试图在Angular2中使用templateUrl访问定制的html。
这是我的login.component.ts
import {Component } from @ angular / core';
@Component({
selector:'login',
templateUrl:'./login.component.html'
})
export class loginComponent {
}
这是我的login.component。 html
< div class =container>
< input type =textplaceholder =username>
< input type =textplaceholder =password>
<按钮>登录< /按钮>
< / div>
我的目录结构中包含login.component.ts和login.component.html,两者都相同位置。
当我编译这段代码时,我收到一个错误消息,说明
localhost:8081 / login.component.html找不到404
未处理的承诺拒绝:未能加载login.component.html;
区域:;任务:Promise.then;价值:无法加载
login.component.html undefined
配置你的应用程序使用相对url
$ p
$ b $ p $ <$> {
compilerOptions:{
module:commonjs,
target:es5,
// ...其他选项
}
}
login.component.ts < 从'@ angular / core'导入{Component}; 关键教训是在@Component 不要忘记tsconfig.json中的module:commonjs。 这个 https://blog.thoughtram.io/angular/2016/06/08/component -relative-paths-in-angular-2.html I tried to access a custom built html using templateUrl in Angular2. Here is my login.component.ts Here is my login.component.html My directory structure has both the login.component.ts and login.component.html both in the same location. When I compile this code I am getting an error stating localhost:8081/login.component.html not found 404 Unhandled Promise rejection: Failed to load login.component.html ;
Zone: ; Task: Promise.then ; Value: Failed to load
login.component.html undefined
you need config your app to using relative url tsconfig.json login.component.ts import {Component} from '@angular/core';
The key lesson is to set the moduleId : module.id in the @Component
decorator! Without the moduleId setting, Angular will look for our
files in paths relative to the application root. And don’t forget the "module": "commonjs" in your tsconfig.json. The beauty of this
component-relative-path solution is that we can (1) easily repackage
our components and (2) easily reuse components… all without changing
the @Component metadata. https://blog.thoughtram.io/angular/2016/06/08/component-relative-paths-in-angular-2.html 这篇关于错误:未捕获(承诺):无法加载login.component.html的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
$ b
moduleId:module.id,//完全解析的文件名;在模块加载时定义
选择器:'login',
templateUrl:'./login.component .html'
})
导出类loginComponent {
}
装饰器中设置moduleId:module.id!如果没有moduleId设置,Angular会在相对于应用程序根目录的路径中查找我们的
文件。
组件相对路径解决方案的优点是我们可以(1)轻松重新包装
组件,(2)轻松重用组件...全部不用改变
的@Component元数据。
import {Component} from '@angular/core';
@Component({
selector: 'login' ,
templateUrl : './login.component.html'
})
export class loginComponent{
}
<div class="container">
<input type="text" placeholder="username">
<input type="text" placeholder="password">
<button>Login</button>
</div>
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
//... other options
}
}
@Component({
moduleId: module.id, // fully resolved filename; defined at module load time
selector: 'login' ,
templateUrl : './login.component.html'
})
export class loginComponent{
}
