How to Localize Placeholder Text in React Rich Text Editor?

This article explains how to implement localization for the placeholder text in a React Rich Text Editor component using React. The implementation uses the Syncfusion React Rich Text Editor component to switch between English and German localizations dynamically.

Step-by-Step Implementation

Import Necessary Modules

Importing necessary functions and components from React and Syncfusion packages is crucial. This includes the RichTextEditorComponent from Syncfusion and a localization module (L10n) for translating text.

import React, { useState } from 'react';
import { RichTextEditorComponent, Inject, Toolbar, Image, Link, HtmlEditor, QuickToolbar } from '@syncfusion/ej2-react-richtexteditor';
import { L10n } from '@syncfusion/ej2-base';

Define Localization Data

The localizationData object contains translations for the Rich Text Editor component. Each language has its translations for different toolbar options like Bold, Italic, etc.

  const localizationData = {
    'en-US': {
      richtexteditor: {
        bold: 'Bold',
        italic: 'Italic',
        underline: 'Underline',
        formats: 'Formats',
        alignments: 'Alignments',
        unorderedList: 'Bulleted List',
        orderedList: 'Numbered List',
        createLink: 'Insert Link',
        image: 'Insert Image',
        sourcecode: 'Code View',
        redo: 'Redo',
        undo: 'Undo',
          // Other toolbar translations...
      },
    },
    'de-DE': {
      richtexteditor: {
        bold: 'Fett',
        italic: 'Kursiv',
        underline: 'Unterstreichen',
        formats: 'Formate',
        alignments: 'Ausrichtungen',
        orderedList: 'Geordnete Liste einfügen',
        unorderedList: 'Ungeordnete Liste einfügen',
        createLink: 'Link einfügen',
        image: 'Bild einfügen',
        sourcecode: 'Quellcode',
        redo: 'Wiederholen',
        undo: 'Rückgängig',
          // Other toolbar translations...
      },
    },
  };

State Initialization and Localization Loading

let placeholder = 'Type something';
let rteObj;
const [locale, setLocale] = useState('en-US');

// Load initial locale
L10n.load({[locale]: localizationData[locale]});

Locale Change Handling

handleLocaleChange: This function updates the application’s locale based on user selection from the dropdown. It modifies the rteObj’s placeholder text between English and German and loads the respective localization data.

 const handleLocaleChange = (event) => {
    const selectedLocale = event.target.value;
    setLocale(selectedLocale);
    rteObj.placeholder = selectedLocale === 'en-US' ? placeholder : 'Text eingeben';
    L10n.load({ [selectedLocale]: localizationData[selectedLocale] });
  };

Rich Text Editor Rendering

Dropdown for Locale Selection: The component renders a dropdown menu that allows users to select their desired language. Upon selection, the handleLocaleChange function is triggered.
RichTextEditorComponent: This component is customized based on the selected language (locale), and its placeholder is adaptable to the language choice. The Inject component is utilized to add features like Toolbar, Image, Link, HtmlEditor, and QuickToolbar to the Rich Text Editor.

  return (
    <div className="control-pane">
      <br />
      <br />
      <br />
      <br />
      <label htmlFor="localeSelector">Select Locale: </label>
      <select id="localeSelector" onChange={handleLocaleChange} value={locale}>
        <option value="en-US">English</option>
        <option value="de-DE">Deutsch</option>
      </select>
      <RichTextEditorComponent
        ref={(richtexteditor) => {
          rteObj = richtexteditor;
        }}
        height={450}
        locale={locale}
        placeholder={placeholder}
      >
        <Inject services={[Toolbar, Image, Link, HtmlEditor, QuickToolbar]} />
      </RichTextEditorComponent>
    </div>
  );
}
export default Default;

This implementation allows for easy localization of the placeholder text in the Rich Text Editor Component, making it adaptable to different languages or regions.
