JavaScript

function A(a)
{
	function B(b)
	{
		function C()
			{
				self.Close();//It will do function for abort file..
			}//C
		return Xhr;
	}//B
}//A
//on every file selection
   $("input[type=file]").live("change",function(){
   var obj = this;
   xhr1 = A(obj);
 
 $(".CancelUpload").live("click",(function () { a().b().c()
or self.close();
 }));
                           
 });

I tried it already but it will abort on click of first cancel button instance..
I am providing seperate cancel button for each file upload progress for that file only...
