Employing the new operator in conjunction with a variable

Is there a way to achieve the following scenario:

var foo = function(){
   this.value = 1;
}
var bar = "foo";
var baz = new bar();
alert(baz.value)     // 1

Specifically, I am looking for a method to instantiate an object using its string name. Any suggestions?

Answer №1

function example(){
   this.number = 10;
};
var variable = "example";
var instance = new this[variable](); // In this context, "this" is referring to the global object (you could also specify "window" but "this" is more concise)
alert(instance.number)     // 10
