Tengo un pedazo de código como ese:

$(function() {
var uploader1 = new plupload.Uploader({
    runtimes : 'gears,html5,flash,silverlight,browserplus',
    browse_button : 'pickfiles1', 
    container : 'container',
    max_file_size : '10mb',
    url : 'upload.php',
    flash_swf_url : '/plupload/js/plupload.flash.swf',
    silverlight_xap_url : '/plupload/js/plupload.silverlight.xap',
    filters : [
        {title : "Image files", extensions : "jpg,gif,png"},
        {title : "Zip files", extensions : "zip"}
    ],
    resize : {width : 320, height : 240, quality : 90}
});

uploader1.bind('Init', function(up, params) {
    $('#filelist1').html("<div>Current runtime: " + params.runtime + "</div>");
});

$('#uploadfiles1').click(function(e) {
    uploader1.start();
    e.preventDefault();
});

uploader1.init();

uploader1.bind('FilesAdded', function(up, files) {
    var temp_img_name = '';
    $.each(files, function(i, file) {
        $('#filelist1').append(
            '<div id="' + file.id + '">' +
            file.name + ' (' + plupload.formatSize(file.size) + ') <b></b> <input type="hidden" name="hdnPictureNameAddtemp" value="' + file.name + '"/>' +
        '</div>');
        if(temp_img_name == ''){
        temp_img_name += file.name;
        } else {
        temp_img_name += ', ' + file.name;
        }

    });
    $('#filelist1').append('<input type="hidden" name="hdnPictureNameAdd" value="' + temp_img_name + '"/>');

    up.refresh(); // Reposition Flash/Silverlight
});

uploader1.bind('UploadProgress', function(up, file) {
    $('#' + file.id + " b").html(file.percent + "%");
});

uploader1.bind('Error', function(up, err) {
    $('#filelist1').append("<div>Error: " + err.code +
        ", Message: " + err.message +
        (err.file ? ", File: " + err.file.name : "") +
        "</div>"
    );

    up.refresh(); // Reposition Flash/Silverlight
});

uploader1.bind('FileUploaded', function(up, file) {
    $('#' + file.id + " b").html("100%");
});
});

Mi problema es que quiero crear un bucle porque es necesario cambiar algunas partes del código anterior. De hecho, uploader1, filelist1, pickfiles1, uploadfiles1 deben cambiarse. Su último número debería aumentar de 1 a n. Intenté todo para crear un bucle pero parece que no funciona.

Además, este código se utiliza para controlar elPLupload
