Determine original name of variable after its passed to a function.

I would like to know if its possible to get the actual name of a variable.

For example:

var foo = 'bar';
function getName(myvar) {  
  //some code
  return "foo"  
};  

So for getName(foo) will return “foo”

Is that possible ?

Thanks.

I don’t think it is possible. When you call a function you pass an object, not a variable. The function doesn’t care where the object came from.

You can go the other way though if you call your function as follows:

getName('foo') 

Or pass both the value and the name:

getName(foo, 'foo')
