Dojo. declare has three parameters,
Parameter 1: Class Name className

Var className = "Person ";
// Define the constructor and Method
Var proto = {
Constructor: function (name) {this. name = name ;},
GetName: function () {return this. name ;},
SetName: function (name) {this. name = name ;}
}

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

// Create an object
Var p = new Person ("tom ");
Console. log (p. getName (); // tom

Console. log (p instanceof Person); // true
Console. log (p. constructor === Person); // true
