I'm trying to figure out whether it is possible to get object name out of variable that is just pointing to it.

So lets say I have code like this:

var myObj = {
   content: "this is my object"
}

var pointer = myObj;
// any way to get "myObj" string from "pointer" variable?

var myFunc = function(parameter) {
   console.log(parameter)
   // any way to get "myObj" string from "parameter" variable inside function?
}
myFunc(myObj)

Any way to get original object name in Javascript as string rather than object itself?

Can it be done some other way if above methods cannot be used?

myObj is not the original object name, but rather the name of the variable that holds a reference to your object. From that perspective, it is really no different than pointer.

To my knowledge, it is currently not possible to get the names of the variables holding a reference to an object from the object alone.

Hope it will help.

var myObj = {
   content: "this is my object"
   name : 'myobj'
}

var pointer = myObj;
// any way to get "myObj" string from "pointer" variable?
//string variable.
name = pointer.name;

var myFunc = function(parameter) {
   console.log(parameter.name)
   // any way to get "myObj" string from "parameter" variable inside function?
}
myFunc(myObj)

    I mean, sure it works, so does `var x = 1 + 1`, but the code is not doing what was asked. – Kevin B Jul 14 '16 at 15:45
  • You have asked is it possible. And i have just show you a way to do that. – Pirate Jul 14 '16 at 15:47
  • well, no, your code stores the name of the variable somewhere else, and you get it from that rather than from the value, which is what was being asked. – Kevin B Jul 14 '16 at 15:48
  • that's indeed workaround I was thinking about and which I have as a plan B, but was hoping for some more neat solution – R1cky Jul 14 '16 at 16:07

From what I understand you want to get the object name which is passed thru as a parameter, not the object value.

If so in myFunc do:

for (n in parameter) { console.log(n); }
