Modification de script JS

Bonsoir,

Je suis entrain de modifier un script d'upload.

Ce script ajax liste les fichier est ajouter des fonction en fonction du type de fichier.

Actuellement on peut voir un bouton "Resize this image" pour les image, j'aimerai ajouter un bouton écouter pour les .MP3.

Voici le code JS :

/* Warning, do not modify this file unless you know what you're doing. */

var rowcolor1 = '#F5F5F5'; // color 1 for the rows
var rowcolor2 = '#FBFBFB'; // alternate color for the rows
var rowcolor3 = '#FBFFDF'; // highlight

var arrowUp = '<img src="templates/default2/images/arrowup.gif" alt="" />';
var arrowDown = '<img src="templates/default2/images/arrowdown.gif" alt="" />';
var sortDirection = { 'ext':0, 'name':0, 'size':0, 'date':1 }
var currentSort = '';
var icons_url = 'templates/default2/images/icons/';

addOnLoadFunc ( drawFilesTable );
addOnLoadFunc ( function () { myFilesSort ( 'date' ); } );

function checkFiles ( fileType )
{
    for ( var i = 0; i < files.length; i++ )
    {
        var box = 'mf_checkbox_' + i;

        switch ( fileType )
        {
            case 0 : checkIt ( getObj ( box ), 1 ); break;
            case 1 : checkIt ( getObj ( box ), 0 ); break;
            case 2 : checkIt ( getObj ( box ), ( files[i][9] == 'jpg' || files[i][9] == 'gif' || files[i][9] == 'png' || files[i][9] == 'jpeg' || files[i][9] == 'bmp' ) ); break;
            case 3 : checkIt ( getObj ( box ), ( files[i][9] != 'jpg' && files[i][9] != 'gif' && files[i][9]!= 'png' && files[i][9] != 'jpeg' && files[i][9] != 'bmp' ) ); break;
            case 4 : checkIt ( getObj ( box ), !getObj ( box ).checked ); break;
        }
        highlightRow ( i );
    }
    for ( var i = 0; i < 5; i++ )
    {
        var o = getObj ( 'select_' + i );
        o.className = fileType == i ? 'link_clicked' : 'link';
    }
}
