| 25. 9. 7. Prototype Chaining |
|
|
The downside to prototype chaining is that it has no support for multiple inheritance. |
Prototype chaining involves overwriting the prototype property of the class with another type of object. |
You can set the prototype property of SubClass to be an instance of BaseClass to inherit all the properties and methods of BaseClass. |
|
function BaseClass() {
}
BaseClass.prototype.color = "red";
BaseClass.prototype.sayColor = function () {
alert(this.color);
};
function SubClass() {
}
SubClass.prototype = new BaseClass();
