我刚刚开始玩 angular2 并尝试用 css-animator 做一些动画

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"));
}
}
我得到 animation_builder.js:434 Uncaught ReferenceError: Exports is not Defined 和 localhost/:18 Error: Error: XHR error (404 Not Found) loading http://localhost:浏览器控制台上的 3000/node_modules/css-animator(…)。
有人可以帮我解决这个问题吗？
谢谢。
最佳答案
您包括animation_builder.js直接在 <head>部分:
<script src="node_modules/css-animator/builder/animation_builder.js"></script>
您会收到引用错误，因为 css-animator 中包含单个文件包被编译为 CommonJS，浏览器本身无法理解。
尝试删除该行，如果您将文件导入到某个地方，SystemJS 应该会自动加载这些文件。 SystemJS 也理解 CommonJS。
或者，您可以将包提供的 SystemJS 包包含在 <head> 中。部分。如果您随后从 css-animator 导入模块，SystemJS 已注册该模块并可以立即加载它。
您可以像这样包含缩小或未缩小的 bundle :
<!-- 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:我是这个包的作者。
关于typescript - 尝试导入 css-animator 时，Angular2/Typescript 返回 404 not found，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37993651/
