Question

How do I add properties to an instance of a new function?

For example:

function Constructor() {
    this.color = "red";
}

var s = new Constructor() {
    this.color = "blue";
    this.height = 30px;
}

When s.height is invoked, I am getting an undefined result. How does one execute this properly?

Answer 1

function Constructor() {
   this.color = "red";
}

var s = new Constructor();
s.color = "blue";
s.height = 30px;
