Further Adventures

Listing 15.08 - A message view - Task 4

Change the program to display messages like "The message is: Hello"

(function () {

    var getMessageInfo = function (messageData) {
        return "The message is: " + messageData;
    };

    var render = function (message) {
        console.error(getMessageInfo(message));
    };

    if (window.theCrypt === undefined) {
        window.theCrypt = {};
    }

    theCrypt.messageView = {
        render: render
    };

})();

Listing 15.08 - A message view - Task 5

Change the program to display messages in upper case.

(function () {

    var getMessageInfo = function (messageData) {
        return messageData.toUpperCase();
    };

    var render = function (message) {
        console.error(getMessageInfo(message));
    };

    if (window.theCrypt === undefined) {
        window.theCrypt = {};
    }

    theCrypt.messageView = {
        render: render
    };

})();
