Uploadify檢查進度

Question

我需要禁用，而該文件上傳提交按鈕..

<button type="submit" id="submit_button" class="btn btn-default">Odeslat</button> 

JS：

$('#file_upload').uploadify({ 
    'swf' : 'css/uploadify.swf', 
    'uploader' : 'uploadify.php?galerie=<?php echo $n; ?>', 
    'onUploadProgress' : function(file) { 
     $('#submit_button').prop('disabled', true); 
    } 
}); 

但這不是工作..
