[removed] interpret string as object reference? [duplicate]

Answer 1

The only way, as it seems to me, would be to use eval. But as they say, eval is evil - but not in controlled environments. This is the way it is possible, but i don't recommend using eval, unless it is absolutely necessary.

var myObject = new MyObject();
var myString = "myObject";
var wantThisToWork = eval(myString).myproperty;

Answer 2

You can use the eval function.

eval(myString).myproperty

Careful with eval, though, if this is something the user is inputting, it will execute any javascript code!

Answer 3

Use eval()

var myObject = {};
myObject.myproperty = "Hello";
var myString = "myObject";

var wantThisToWork = eval(myString).myproperty;

Answer 4

If the variable is in the global scope, you can access it as a property of the global object

var a = "hello world";
var varName = "a";
console.log( window[varName] ); // outputs hello world
console.log( this[varName] ); // also works (this === window) in this case

However, if it's a local variable, the only way is to use eval (disclaimer)

function () {
  var a = "hello world";
  var varName = "a";
  console.log( this[varName] ); // won't work
  console.log( eval(varName) ); // Does work
}

Unless you can put your dynamic variables into an object and access it like a property

function () {
  var scope = {
    a: "hello world";
  };
  var varName = "a";
  console.log( scope[varName] ); // works
}
