How to find out the name of a "class" in JS when passing it to a function?

Question

JavaScript

There is a "class":

Class = function( )
{
  // ***
};

Class.prototype.func = function( layer )
{
  // ***
};

I do inheritance:

boot.inherit = function( Child, Parent )
{
  // Наследуемся
};

boot.inherit( newClass, Class );

Question: How can I find out the name of the Parent (the variable to which the function is assigned) , without having to write it as a parameter?

Answer 1

You are using an anonymous function, so no way.
If you have a named function, it has a name property . It is not supported by IE, if you need its support - you can tear out the name from the source of the function.

function Class(){}
Class.name // => 'Class'
function getName(it){
  var match = /^\s*function\s+(\b\w+\b)/.exec(it);
  if(match)return match[1];
}
getName(Class) // => 'Class''

However, this is less than completely useless - after compressing your code, the name of the constructor and, accordingly, the value of the name property will turn from 'Class' to some 'tF'.
If you need to get exactly the name of the function - add to the function and use the displayName property - in one go and improve code profiling .

function Class(){}
Class.displayName = 'Class';
