Variable name as a string in Javascript

Question

Is there a way to get a variable name as a string in Javascript? (like NSStringFromSelector in Cocoa)

I would like to do like this:

var myFirstName =         


        

Answer 1

When having a function write a function that changes different global variables values it is not always myfirstname it is whatever happens to be passing through. Try this worked for me.

_{Run in jsfiddle}

var jack = 'jill';
function window_getVarName(what)
{
  for (var name in window)
  {
    if (window[name]==what)
    return(name);
  }
  return("");
}
document.write(window_getVarName(jack));

Will write to the window 'jack'.
