使用Cordova Media插件修改代码

Question

我找到了一个使用Media Plugin播放音频的Cordova Android App示例，它运行正常。它随机播放不同的音频。

这是代码：

    //Global media file var
var my_media;

function getSong(){
    listDirectory();
}

function listDirectory() {

    window.resolveLocalFileSystemURL(cordova.file.applicationDirectory + "www/audio/", function (dirEntry) {
        var directoryReader = dirEntry.createReader();
        directoryReader.readEntries(dirSuccess,dirFail);
    });

}

function dirSuccess(entries) {
    console.log("INFO: Listing entries");

    // Bellow Code lists all the files
    /*
    var i;
    for (i=0; i<entries.length; i++) {
        console.log(entries[i].name);
    }
    */

    // Bellow Code Gets single entry by day.
    // PS you will need 365 sound files 
    // or you will receive an error that the file does not exist
    /*
    console.log(entry[dayOfYear()].name);
    */

    // Bellow code gets a random file
    var randomIndex = Math.floor( Math.random() * entries.length );
    var theFile = entries[randomIndex];
    document.getElementById( 'quote' ).innerHTML = theFile.name;
    //console.log(theFile);
    //console.log("tx object " + JSON.stringify(theFile));
    playSong(theFile.nativeURL);

}

function dirFail(error) {
console.log("Failed to list directory contents: " + error.code);
}

function dayOfYear(){
    var now = new Date();
    var start = new Date(now.getFullYear(), 0, 0);
    var diff = now - start;
    var oneDay = 1000 * 60 * 60 * 24;
    var day = Math.floor(diff / oneDay);
    return day;
}

function playSong(src){
    // Audio player

    if(my_media){
        my_media.stop();
        my_media.release();
    }

    my_media = new Media(src, onSuccess, onError);

    // Record audio
    my_media.play();

}

function onSuccess(){}

function onError(error) {
console.log("Failed to play file: " + error.code);
}

我需要的是使用不同的按钮播放不同的声音： 按钮1播放声音1 按钮2播放声音2 .....

如果有人可以帮助修改代码，我将非常感激。
