Question

I want to use the value of a variable to access an object.

Let’s say I have an object named myobject.

I want to fill a variable with this name and use the variable to access the object.

Example:

var objname = 'myobject';
{objname}.value = 'value';

Global:

myObject = { value: 0 };
anObjectName = "myObject";
this[anObjectName].value++;

console.log(this[anObjectName]);

Global: v2

var anObjectName = "myObject";
this[anObjectName] = "myvalue"

console.log(myObject)

Local: v1

(function() {
    var scope = this;

    if (scope != arguments.callee) {
        arguments.callee.call(arguments.callee);
        return false;
    }

    scope.myObject = { value: 0 };
    scope.anObjectName = "myObject";
    scope[scope.anObjectName].value++;

    console.log(scope.myObject.value);
})();

Local: v2

(function() {  
    var scope = this;

    scope.myObject = { value: 0 };
    scope.anObjectName = "myObject";
    scope[scope.anObjectName].value++;

    console.log(scope.myObject.value);    
}).call({});
