string. Le nom du message, tel que spécifié dans le fichier messages.json. Si le message ne peut pas être trouvé dans messages.json :

Exemples

Obtenez la chaîne localisée pour "messageContent", avec target.url substitué :

var message = browser.i18n.getMessage("messageContent", target.url);
console.log(message);

Cela fonctionnerait avec un fichier _locales/en/messages.json contenant :

{
  "messageContent": {
    "message": "You clicked $URL$.",
    "description": "Tells the user which link they clicked.",
    "placeholders": {
      "url" : {
        "content" : "$1",
        "example" : "https://developer.mozilla.org"
      }
    }
  }
}

Si target.url est "https://developer.mozilla.org", alors la valeur de message, dans la locale "en", serait :

"You clicked https://developer.mozilla.org."
