Adapting Your Website to Language Changes

The ability to seamlessly switch between languages enhances user experience and makes your website more accessible to a diverse audience. Let's explore the steps involved in achieving this functionality.

Obtain Browser Language

To start, you need to obtain the user's preferred languages, ordered by preference. The JavaScript navigator interface provides a convenient way to access this information.

navigator.languages; // ['en-US', 'en', 'es']

This array contains the user's preferred languages, with the most favored language listed first. If you specifically want to retrieve the most preferred language, you can use the navigator.language property.

navigator.language; // 'en-GB'

Listen to Language Change Event

The next step is to detect changes in the browser's language. JavaScript facilitates this through the languagechange event.

document.addEventListener(
    "languagechange", (event) => {
        // update the language
    }
);
