Question

我想在angular2中使用颜色选择器。我尝试使用npm angular2-color-picker库。但是在包含该指令后我只能看到一个空白屏幕。（在控制台中找不到错误）。请通过了解我出错的地方帮助我，或者让我知道是否还有其他angular2库可用于采摘颜色。提前谢谢。

我的HTML包括：

<div>
<label>Primary</label>
<input [(colorPicker)]="color" [style.background]="color" [value]="color"/>
</div>

我的TS :( AppComponent页面路由到DesignPage）

import {Component, OnInit} from 'angular2/core';
import {ColorPickerDirective} from 'angular2-color-picker/app/color-picker/color-picker.directive';
@Component({
    selector: 'my-design',
    templateUrl: 'wwwWeb/build/component/design/design.html',
    directives: [ColorPickerDirective]
})
export class DesignPage implements OnInit {
 private color: string = "#127bdc";
}

我的Boot.ts

import {bootstrap} from 'angular2/platform/browser';
import {AppComponent} from './app.component';
import {ColorPickerService} from './color-picker/color-picker.service'

bootstrap(AppComponent, [ColorPickerService]);

我的Tsconfig

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "../node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}

您需要以这种方式配置库：

System.config({
  map: {
    'angular2-color-picker': 'node_modules/angular2-color-picker'
  },
  packages: {
    (...)
    'angular2-color-picker': {
      format: 'register',
      defaultExtension: 'js'
    }
  }
});
