iFrameFormRequest

This class gives you a method to upload files 'the ajax way'. Attach the iFrameFormMethod to any form tag and you can upload files

How to use

#JS
var iFrame = new iFrameFormRequest(document.getElement('form'),{
	onRequest: function(){
		document.id('debug').set('text','start');
	},
	onComplete: function(response){
		document.id('debug').set('html',response);
	}
});

Or you can use it this way:

#JS
document.getElement('form').iFrameFormRequest({
	onRequest: function(){
		document.id('debug').set('text','start');
	},
	onComplete: function(response){
		document.id('debug').set('html',response);
	}
});

And the HTML

#HTML
<form action="upload.php" method="post" enctype="multipart/form-data">	
	<input type="file" name="file" />	
	<input type="submit" value="uploadAjax" />	
</form>

<div id="debug"></div>
