Upload file with jquery.uploadifive.js

Hello, I need a help in an application that I'm giving support, this application uses the jquery.uploadifive.js method in javascript that did so:

<script language="javascript" type="text/javascript">
  $("#encaminharChamado_assuntos").load("xt_mostrarComboAssuntoPorGrupo.php");

$("#reclassificarChamado_assuntos").load("xt_mostrarComboAssuntoPorGrupo.php",
{"intIdGrupo" : <?php echo $objChamado->getIdGrupoDestino();?>,
"intIdAssunto" : <?php echo $objChamado->getIdAssunto();?>});
  $('#strArquivoAnexo').uploadifive({

'uploadScript'  : 'xt_enviarArquivo.php',
'auto'              : true,
'multi'             : false,
'buttonText'   : 'SELECIONAR ARQUIVO',
'width'        : 170,
'onUploadComplete' : function(file, data) {
         processaInicioUpload();

    },
    'onCancel' : function(file) {
       var retorno = $.parseJSON(response);
       processaFimUpload(retorno);

}
});

And even though you are not uploading ... does anyone have examples using this js, to be able to attach? because today the attachment button is in flash.
