javascript - 将 CKEditor 与 Aurelia 集成

Question

我正在开发一个 SPA，需要 WYSIWYG 编辑器。为此，我决定将 CKEditor 与 aurelia、aurelia-cli、npm 和 typescript 结合使用。

我已经安装了npm install ckeditor --save

还在我的 aurelia.json 文件中，我添加了 ckeditor npm 包作为依赖项。

"dependencies": [
      {
        "name": "ckeditor",
        "path": "../node_modules/ckeditor",
        "main": "ckeditor",
        "resources": [
          "config.js",
          "skins/moono-lisa/editor.css",
          "lang/en.js"
        ]
      }
]

我还将 ckeditor.d.ts 类型定义添加到了我的 custom_typings 文件夹中。 https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/ckeditor

此时，当我刷新页面时，出现以下错误:

任何帮助将不胜感激:)

您必须在代码中导入 CKEditor 的脚本。像这样:

import 'ckeditor';

这是生成 CKEditor 的自定义元素的示例。

editor.js

import {inject} from 'aurelia-dependency-injection';
import {bindable} from 'aurelia-templating';
import {bindingMode} from 'aurelia-binding';
import {DOM} from 'aurelia-pal';
import 'ckeditor';

@inject(DOM.Element)
export class Editor {
  @bindable({ defaultBindingMode: bindingMode.twoWay }) value;
  @bindable name;

  constructor(element) {
    this.element = element;
  }

  updateValue() {
    this.value = this.textArea.value;
  }

  bind() {
    this.textArea = this.element.getElementsByTagName('textarea')[0];
    let editor = CKEDITOR.replace(this.textArea);
    editor.on('change', (e) => {
      this.value = e.editor.getData();
    });
  }
}

editor.html

<template>
  <textarea change.delegate="updateValue()"></textarea>
  <input type="hidden" name.bind="name" value.bind="value">
</template>

要在生产环境中使用此功能，您必须导出一些 ckeditor 静态文件，config.js、styles.css、content.css 等。不幸的是，现在无法在 CLI 中执行此操作(我已经制作了一个 PR 来添加此功能 https://github.com/aurelia/cli/pull/415 )。因此，您必须在构建应用程序时创建一个 gulp 任务来导出这些文件。
