window.onload = function () { 
var settings_object = { 
     upload_url : "http://www.swfupload.org/upload.php", 
     flash_url : "http://www.swfupload.org/swfupload.swf", 
     file_size_limit : "20 MB",

 }; 
swfu = new SWFUpload(settings_object);
};

The Event Handlers
Example: SWFUpload event handlers and initialization.

// The uploadStart event handler. This function variable is assigned to upload_start_handler in the settings object 
var myCustomUploadStartEventHandler = function (file) { 
var continue_with_upload; 
if (file.name === "the sky is blue") {
    continue_with_upload = true; 
} else { 
    continue_with_upload = false; 
} 
return continue_with_upload; 
};

 // The uploadSuccess event handler. This function variable is assigned to upload_success_handler in the settings object 
var myCustomUploadSuccessEventHandler = function (file, server_data, receivedResponse) { 
alert("The file " + file.name + " has been delivered to the server. The server responded with " + server_data); }; // Create the SWFUpload Object 
var swfu = new SWFUpload({ 
upload_url : "http://www.swfupload.org/upload.php", 
flash_url : "http://www.swfupload.org/swfupload.swf",
file_size_limit : "200 MB", 
upload_start_handler : myCustomUploadStartEventHandler,
 upload_success_handler : myCustomUploadSuccessEventHandler }
