JavaScript writing class nine _js object oriented

9, Yui writing class way
Here is the introduction of Yui 2.7.0 version, just introduce Yahoo.js. Yui introduced a namespace, similar to the Java package. The following Yahoo Tools function pack

• Yahoo.namespace
• Yahoo.lang
• YAHOO.lang.hasOwnProperty
• YAHOO.lang.extend
• YAHOO.lang.augment
• YAHOO.log
• Yahoo_config and Yahoo.env
• YUI Module Names

Write Class Way:

Copy Code code as follows:

Define Package Name
Yahoo.namespace ("test");

Defining classes
YAHOO.test.Person = function (name) {
THIS.name = name;
}
YAHOO.test.Person.prototype.setName = function (name) {this.name = name;}
YAHOO.test.Person.prototype.getName = function () {return this.name;}


Create an Object
var p = new YAHOO.test.Person ("Jack");

Console.log (P.getname ());//jack
P.setname (' Tom ');
Console.log (P.getname ());//tom

Tests whether instanceof and p.constructor correctly point to the YAHOO.test.Person
Console.log (P instanceof YAHOO.test.Person);
Console.log (P.constructor = = YAHOO.test.Person);

You can see that in addition to the package name, there is no difference from the third way of writing a class.
