如何在CKEditor 5中创建包含文本的不可编辑块。

<div>Non editable message here</div>

仅供参考:她是我最后使用的插件。

您可以创建 widget API

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 );
    } );

toWidget() 将元素向下投射到编辑视图时的函数。此外,该元素应标记为 schema

也不要忘记加载 Widget
