, How to write classes in dojo.js
The latest version of dojo is 1.3.1. I remember it was still 0.4 in 2007. There are gradually more documents, and more and more people use Dojo. Dojo also released a core version, which is only 27kb after compression. Dojo uses the dojo.declare method to define a class. The source code of dojo.declare is not posted here. dojo.declare has three parameters,
Parameter 1: class name className
Parameter 2: inherited class superclass
Parameter 3: constructor, method props
To simply define a class, you only need to pass the first One and three parameters. Because we only discuss how to define a class here, not inheritance. The code is as follows:

Copy code The code is as follows:

//Define class name
var className = "Person";
//Define constructor and method
var proto = {
constructor : function(name){this.name=name;},
getName : function(){ return this.name;},
setName : function(name){ this.name = name;}
}

//Define class Person
dojo.declare(className,null, proto);

//Create an object
var p = new Person("tom");
console.log(p.getName());//tom
p. setName("jack");
console.log(p.getName());//jack

//Test whether instanceof and p.constructor correctly point to Person
console.log( p instanceof Person);//true
console.log(p.constructor === Person);//true
