CKEditor 5粘贴为纯文本 [英] CKEditor 5 paste as plain text
问题描述
是否可以将剪贴板中的所有内容始终粘贴为纯文本格式?
Is there an option to paste always from the clipboard as plain text?
我尝试过这种方法,但这不起作用:
I tried it that way, but that does not work:
$(document).ready(function () {
ClassicEditor.create(document.querySelector('#text'), {
toolbar: [
'heading',
'bold',
'italic',
'link',
'bulletedList',
'numberedList',
'blockQuote',
'undo',
'redo'
]
}).then(function (editor) {
this.listenTo(editor.editing.view, 'clipboardInput', function (event, data) {
// No log.
console.log('hello');
});
}).catch(function (error) {
});
});

推荐答案
clipboardInput
事件在 Document
,而不是 视图
。因此,第一件事就是监听正确的对象。
The clipboardInput
event is fired on the Document
, not the View
. So the first thing will be to listen on the right object.
第二件事是确保插入到编辑器中的内容是纯文本。这可以通过两种方式完成:
The second thing is ensuring that the content inserted into the editor is a plain text. This can be done in two ways:
- 从剪贴板中获取的HTML可以纯文本格式。但这很难。
- 我们可以从剪贴板中获取纯文本并将其插入编辑器中。但是,编辑器希望粘贴HTML,因此您需要 HTMLize此纯文本。 CKEditor 5为此提供了一个功能–
plainTextToHtml()
。
要覆盖编辑器的默认行为,我们需要覆盖此回调: https://github.com /ckeditor/ckeditor5-clipboard/blob/a7819b9e6e2bfd64cc27f65d8e56b0d26423d156/src/clipboard.js#L137-L158
To override the editor's default behaviour we'll need to override this callback: https://github.com/ckeditor/ckeditor5-clipboard/blob/a7819b9e6e2bfd64cc27f65d8e56b0d26423d156/src/clipboard.js#L137-L158
要做到这一点,我们会听同样的话事件(具有更高的优先级),请执行所有相同的操作,但是忽略剪贴板数据的 text / html
风格。最后,我们将调用 evt.stop()
阻止默认监听器被执行并破坏我们的工作:
To do that, we'll listen to the same event (with a higher priority), do all the same things, but ignore text/html
flavour of the clipboard data. Finally, we 'll call evt.stop()
to block the default listener from being executed and ruining our job:
import plainTextToHtml from '@ckeditor/ckeditor5-clipboard/src/utils/plaintexttohtml';
// ...
const clipboardPlugin = editor.plugins.get( 'Clipboard' );
const editingView = editor.editing.view;
editingView.document.on( 'clipboardInput', ( evt, data ) => {
if ( editor.isReadOnly ) {
return;
}
const dataTransfer = data.dataTransfer;
let content = plainTextToHtml( dataTransfer.getData( 'text/plain' ) );
content = clipboardPlugin._htmlDataProcessor.toView( content );
clipboardPlugin.fire( 'inputTransformation', { content, dataTransfer } );
editingView.scrollToTheSelection();
evt.stop();
} );
