There is another technique in applying CALL and apply, that is, after applying CALL and apply to another function (class), the currentA function (class) has another function (class) method or attribute, which can also be called "inheritance ". See the following example:
// Inherited demoFu
(this, arguments );}}}
Resolution: From the code, this object only contains one method: Create, which returns a function, that is, a class. But this is also a classThe constructor calls initialize, which is the initialization function defined during class creation. In this way,The class Creation Mode in prototype can be implemented.Example:Copy codeThe Code is as follows: var vehicle = Class. Create ();Vehicle. Prototype = {Initialize: function (type ){This. type = type;}Showself: function ()
Is the iPhone the first mobile phone of apple?
In fact, this question is a little "white". I would like to say a few more words to the small K who pays attention to the history of some enterprises. IPhone is Apple's mobile phone designed and manufactured by itself, but it is not Apple's first mobile phone.
So what is the first mobile phone related to Apple?
When you buy a mobile phone, are you entangled in several mobile phones? Do you still remember the times when I heard "hellomoto" in mantai
is as follows: var class = {Create: function (){Return function (){This. Initialize.

time the class is created. In this way, you can implement the class creation pattern in prototypeExample: var vehicle=class.create (); vehicle.prototype={initialize:function (type) {this.type=type; }, Showself:function () {alert ("This vehicle is" + this.type); }}var moto=new vehicle ("moto"); Moto.showself ();Operation Result: Thisvehicle is Moto Example 3:f
