Example - Declaring an editor as a class

The following example implements the @handsontable/vue3 component with a custom editor added, utilizing the placeholder attribute in the editor's input element.

import { createApp } from 'vue'; import { HotTable } from '@handsontable/vue3'; import { TextEditor } from 'handsontable/editors/textEditor'; import { registerAllModules } from 'handsontable/registry'; // register Handsontable's modules registerAllModules(); class CustomEditor extends TextEditor { constructor(props) { super(props); } createElements() { super.createElements(); this.TEXTAREA = document.createElement('input'); this.TEXTAREA.setAttribute('placeholder', 'Custom placeholder'); this.TEXTAREA.setAttribute('data-hot-input', true); this.textareaStyle = this.TEXTAREA.style; this.TEXTAREA_PARENT.innerText = ''; this.TEXTAREA_PARENT.appendChild(this.TEXTAREA); } } const app = createApp({ data() { return { hotSettings: { startRows: 5, columns: [ { editor: CustomEditor } ], colHeaders: true, colWidths: 200, licenseKey: 'non-commercial-and-evaluation' } } }, components: { HotTable, } }); app.mount('#example1'); <script src="https://cdn.jsdelivr.net/npm/handsontable@11.1/dist/handsontable.full.min.js"></script> <link type="text/css" rel="stylesheet" href="https://cdn.jsdelivr.net/npm/handsontable@11.1/dist/handsontable.full.min.css" /> <script src="https://cdn.jsdelivr.net/npm/vue@3/dist/vue.global.prod.js"></script> <script src="https://cdn.jsdelivr.net/npm/@handsontable/vue3@11.1/dist/vue-handsontable.min.js"></script> <script src="https://handsontable.com/docs/11.1/scripts/fixer.js"></script> <script src="https://handsontable.com/docs/11.1/scripts/helpers.js"></script> <div id="example1"> <hot-table :settings="hotSettings"></hot-table> </div>
