The Mega App model and API

The Mega App model contains only one JavaScript object that represents the voice and photo memo data, as shown in the following code snippet:

var MemoItem = function(memoItem) {
    this.id = memoItem.id || "Memo_" + (new Date()).getTime();
    this.title = memoItem.title || "";
    this.desc = memoItem.desc || "";
    this.type = memoItem.type || "voice";
    this.location = memoItem.location || "";
    this.mtime = memoItem.mtime || "";
};

The MemoItem object contains the following attributes:

id: This represents the memo ID (its default value is unique as it includes a numeric value of the current time in milliseconds)
title: This represents the memo title
desc: This represents the memo description
type: This represents the memo type, and it can be "voice" or "photo" (its default value is "voice")
location: This represents the location of the media (audio or photo) file in the device's filesystem
mtime: This represents the time when the memo was created
