Custom editor example

An implementation of the @handsontable/angular component with a custom editor added. It utilizes the placeholder attribute in the editor's input element.

// app.component.ts import { Component } from '@angular/core'; import * as Handsontable from 'handsontable'; class CustomEditor extends Handsontable.editors.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; Handsontable.dom.empty(this.TEXTAREA_PARENT); this.TEXTAREA_PARENT.appendChild(this.TEXTAREA); } } @Component({ selector: 'app-root', template: ` `, }) class AppComponent { hotSettings: Handsontable.GridSettings = { startRows: 5, columns: [ { editor: CustomEditor } ], colHeaders: true, colWidths: 200 }; } // app.module.ts import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { HotTableModule } from '@handsontable/angular'; @NgModule({ imports: [ BrowserModule, HotTableModule ], declarations: [ AppComponent ], bootstrap: [ AppComponent ] }) class AppModule { } // bootstrap import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; platformBrowserDynamic().bootstrapModule(AppModule).catch(err => { console.error(err) });
