Overview

You can localize labels on Median's Tab Menu when using the Dynamic Tab Menu feature. This requires retrieving the user's language settings and rendering the labels based on a translation dictionary. The sample code provided below demonstrates how to translate a basic bottom tab bar into five languages: English, French, Spanish, German, and Italian.

JavaScript Implementation

↔️Median JavaScript Bridge

JavaScript

// Get the user's language
let userLanguage = navigator.language || navigator.userLanguage;
let languageCode = userLanguage.split('-')[0];

// Function to localize the tab items
function localizeTabItems(tabItems) {
   // Define translations for the labels
   const translations = {
'en': {
    'Tab 1': 'Tab 1',
    'Tab 2': 'Tab 2',
    'Tab 3': 'Tab 3'
},
'fr': {
    'Tab 1': 'Onglet 1',
    'Tab 2': 'Onglet 2',
    'Tab 3': 'Onglet 3'
},
'es': {
    'Tab 1': 'Pestaña 1',
    'Tab 2': 'Pestaña 2',
    'Tab 3': 'Pestaña 3'
},
'de': {
    'Tab 1': 'Register 1',
    'Tab 2': 'Register 2',
    'Tab 3': 'Register 3'
},
'it': {
    'Tab 1': 'Scheda 1',
    'Tab 2': 'Scheda 2',
    'Tab 3': 'Scheda 3'
}
   };

   // Get the user's language
   const userLanguage = navigator.language || navigator.userLanguage;
   const languageCode = userLanguage.split('-')[0];

   // Check if the translations exist for the user's language
   const userTranslations = translations[languageCode] || translations['en'];

   // Update the labels in the tabItems array
   return tabItems.map(item => ({
...item,
label: userTranslations[item.label] || item.label
   }));
}

const tabItems = [
   {
icon: "fas fa-cloud",
label: "Tab 1",
url: "javascript:alert('You selected tab 1')",
   },
   {
icon: "fas fa-globe",
label: "Tab 2",
url: "javascript:alert('You selected tab 2')",
   },
   {
icon: "fas fa-users",
label: "Tab 3",
url: "javascript:alert('You selected tab 3')",
   },
];

// Localize tab bar items
const localizedTabItems = localizeTabItems(tabItems);

// Render bottom tab bar
function median_library_ready() {
   median.tabNavigation.setTabs({ enabled: true, items: localizedTabItems });
}
