Valums multi file uploading

I am using Valums AJAX javascript, found at http://valums.com/ajax-upload/ I am using VB.net as my server side scripting language and I have a webservice that is called, but I do not know how to retrieve the query string sent by his code. Can some help me开发者_如何学Go?

looks like you have access to these methods:

onSubmit: function(id, fileName){},
onProgress: function(id, fileName, loaded, total){},
onComplete: function(id, fileName, responseJSON){},
onCancel: function(id, fileName){},

I would imagine that the onComplete method is what you would most likely want if you wanted to show something once the entire process was done. I would guess the responseJSON value is what you would most likely want to check.
