Override the keyboard shortcuts in Vue Document editor component

11 Jun 202411 minutes to read

Document Editor triggers the keyDown event every time when any key is entered and provides an instance of DocumentEditorKeyDownEventArgs. You can use the isHandled property to override the keyboard shortcut behavior.

Preventing default keyboard shortcut

The following code shows how to prevent the CTRL + C keyboard shortcut for copying selected content in Document Editor.

    <div style="height:330px">
        <ejs-documenteditor ref="documenteditor" :height="height" style="width: 100%;display:block" :isReadOnly='false'
            :enableSelection='true' :enableSfdtExport='true' :enableEditor='true'

import { DocumentEditorComponent as EjsDocumenteditor, Selection, Editor, SfdtExport } from '@syncfusion/ej2-vue-documenteditor';

const height = '370px';

provide('DocumentEditor ', [SfdtExport, Selection, Editor]);

const onKeyDown = function (args) {
    let keyCode = args.event.which || args.event.keyCode;
    let isCtrlKey = (args.event.ctrlKey || args.event.metaKey) ? true : ((keyCode === 17) ? true : false);
    //67 is the character code for 'C'
    if (isCtrlKey && keyCode === 67) {
        //To prevent copy operation set isHandled to true
        args.isHandled = true;
    }
}

Override or define the keyboard shortcut

Override or define a new keyboard shortcut behavior instead of preventing the keyboard shortcut.

For example, Ctrl + S keyboard shortcut saves the document in SFDT format by default, and there is no behavior for Ctrl + Alt + S. The following code demonstrates how to override the Ctrl + S shortcut to save a document in DOCX format and define Ctrl + Alt + S to save the document in SFDT format.
