Use the chrome.i18n module to manipulate the i18n related browser settings, such as the accept languages, or to get localized messages for current locale.

Examples

The following code gets accept-languages from the browser and display them as a string by separating each accept-language with ','.

function getAcceptLanguages() {
  chrome.i18n.getAcceptLanguages(function(languageList) {
    var languages = languageList.join(",");
    document.getElementById("languageSpan").innerHTML = languages;
  })
}

The following code gets localized message from the browser and displays it as a string. It replaces two placeholders within the message with values arg1 and arg2.

function getMessage() {
  var message = chrome.i18n.getMessage("click_here", ["arg1", "arg2"]);
  document.getElementById("languageSpan").innerHTML = message;
}
