Getting parent function's variable in javascript

function bodycreate(num)
{
   var ref = database.ref('190/ExerciseTable/'+num+'/');
   ref.on('value',gotdata,errData);
}

function gotdata(data)//passes firebase data
{
        var ex3=you.val();
	var sa3=Object.keys(ex3);
	var s3=sa3.length;
	console.log(s3);//prints count of child elements
        console.log(num);//Here I want to print the variable num
}

I want to display the variable num. How can I get it from the parent function. Thanks in advance.

One which I can quickly think is

function bodycreate(num)
{
   var ref = database.ref('190/ExerciseTable/'+num+'/');
   ref.on('value',
         function(data){
           gotdata(data, num)
         },errData);
}

And then change signature of gotdata to receive two arguments.
