Query String
This example demonstrates how to switch language using query string parameter change. i18next language detection plugin use to detect user language in the browser with support for: 1. querystring, 2. cookie, 3. localStorage, 4. navigator, 5. htmlTag. Every time on click or change event, i18next loads json file with selected language and initialize translation on a new page load. To change the language on click, use <a href="?lng=en">EN</a> markup.
Example Markup
<div aria-labelledby="dropdown-flag" class="dropdown-menu dropdown-menu-right">
<a href="?lng=en" class="dropdown-item">
<i class="flag-icon flag-icon-gb"></i> English
</a>
<a href="?lng=es" class="dropdown-item">
<i class="flag-icon flag-icon-es"></i> Spanish
</a>
<a href="?lng=pt" class="dropdown-item">
<i class="flag-icon flag-icon-pt"></i> Portuguese
</a>
<a href="?lng=fr" class="dropdown-item">
<i class="flag-icon flag-icon-fr"></i> French
</a>
</div>
