[Moo] Class Name

[samdev]

I want to throw an Exception and tell user what caused exception in a
form:

  Class::Method

Method name can easily be obtained from:

  arguments.callee

and then processing returned string.

How to get class name inside method?

I create classes next way:

var MyClass = new Class({
  ...
  method: function()
  {
    console.log( 'Want to output class name here.');
  },
  ...
});

You can embed the name of the class in the class itself, like:

var MyClass = new Class({

name: ‘MyClass’,

method: function(){

console.log(this.name);

}

});

or iterate over all variables in window. This doesn’t work with classes that are not in the window space (like Fx.Tween for instance) and is not the fastest solution, but might be enough for your case:

Class.getClassName = function(obj){

for (name in window){

if (window[name] == obj.constructor) return name;

}

return null;

};

var MyClass = new Class({

method: function(){

console.log(Class.getClassName(this));

}

});

Sorry ‘bout that.
