Question

我刚开始玩angular2并试图用css-animator

做一些动画

    "@angular/common": "2.0.0-rc.3",
    "@angular/compiler": "2.0.0-rc.3",

 }

的index.html

        <body class="bg-image">

          </body>
      </html>

systemjs.config.js

var map = {
    'app':                        'app', // 'dist',

    '@angular':                   'node_modules/@angular',

    'css-animator':               'node_modules/css-animator'
  };
   var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js'   },
     };
     System.config(config);

custom.animate.directive.ts

import {Directive, ElementRef, Renderer} from '@angular/core';
 import {AnimationService, AnimationBuilder} from 'css-animator';

 @Directive({
    selector: '[login-method]',
    host: {
      '(click)':'onClick()'
   }
})

export class LoginOptionsDirective{
   private animator : AnimationBuilder;

   constructor(animationService: AnimationService, private el: ElementRef, private renderer: Renderer){
      this.animator = animationService.builder();
  }

  onclick(){
      this.renderer.setElementStyle(this.el, 'color','black');
      console.log(this.el.nativeElement.getAttribute("login-method"));
   }
 }

我在浏览器控制台上获得了animation_builder.js:434 Uncaught ReferenceError: exports is not defined和localhost/:18 Error: Error: XHR error (404 Not Found) loading http://localhost:3000/node_modules/css-animator(…)。

有人可以帮我这个吗？

感谢。

您将animation_builder.js直接包含在<head>部分中：

<script src="node_modules/css-animator/builder/animation_builder.js"></script>

你得到一个ReferenceError，因为css-animator包中包含的单个文件被编译成CommonJS，浏览器本身并不理解。

尝试删除该行，如果您将文件导入某处，SystemJS应自动加载这些文件。 SystemJS也了解CommonJS。

或者，您可以在<head>部分中包含程序包提供的SystemJS包。如果您从css-animator导入模块，SystemJS已经注册了该模块，可以立即加载它。

您可以包含缩小或未缩小的捆绑包，如下所示：

<!-- Unminified Source -->
<script src="node_modules/css-animator/bundles/css-animator.js"></script>

<!-- Minified Source -->
<script src="node_modules/css-animator/bundles/css-animator.min.js"></script>

免责声明：我是这个软件包的作者。

尝试导入css-animator时，Angular2 / Typescript返回404未找到
