javascript - 在 CKEditor 5 中创建带有文本的不可编辑 block

Question

如何在 CKEditor 5 中创建带有文本的不可编辑 block 。

我需要在最终 View 中生成的东西:

<div>Non editable message here</div>

我尝试使用 UIElement，然后设置 innerHTML，但这仍然使元素可编辑。

仅供引用:她是我最终使用的插件。

您可以创建widget API为此:

import Widget from '@ckeditor/ckeditor5-widget/src/widget';
import { toWidget } from '@ckeditor/ckeditor5-widget/src/utils';
import { downcastElementToElement } from '@ckeditor/ckeditor5-engine/src/conversion/downcast-converters';
import { upcastElementToElement } from '@ckeditor/ckeditor5-engine/src/conversion/upcast-converters';

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        plugins: [ Essentials, Paragraph, Widget, /* ... other plugins ... */ ],
        toolbar: [ 'undo', 'redo' ]
    } )
    .then( editor => {
        window.editor = editor;

        const model = editor.model;

        model.schema.register( 'myWidget', {
            inheritAllFrom: '$block',
            isObject: true
        } );

        editor.conversion.for( 'dataDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget',
                view: ( modelItem, writer ) => {
                    return writer.createContainerElement( 'div', { class: 'widget' } );
                }
            } ) );

        editor.conversion.for( 'editingDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget',
                view: ( modelItem, writer ) => {
                    const div = writer.createContainerElement( 'div', { class: 'widget' } );

                    return toWidget( div, writer, { label: 'widget label' } );
                }
            } ) );

        editor.conversion.for( 'upcast' )
            .add( upcastElementToElement( {
                view: {
                    name: 'div',
                    class: 'widget'
                },
                model: 'myWidget'
            } ) );

        editor.setData(
            '<p>foobar</p>' +
            '<div class="widget">Non editable text goes here</div>' +
            '<p>foobar</p>'
        );
    } )
    .catch( err => {
        console.error( err.stack );
    } );

关键点是使用toWidget()将元素向下转换到编辑 View 时的函数。此外，该元素应标记为 schema 中的对象。 .

另外，不要忘记加载 Widget 插件，该插件会打开对小部件的支持。
