Je sais qu'il s'agit d'un ancien post, mais si vous souhaitez créer un ensemble d'instances avec lesquelles vous souhaitez travailler et réutiliser le code, vous pouvez faire quelque chose comme ceci :
"use strict";
// this is derived from several posts here on SO and ultimately John Resig
function makeClassStrict() {
var isInternal, instance;
var constructor = function(args) {
if (this instanceof constructor) {
if (typeof this.init == "function") {
this.init.apply(this, isInternal ? args : arguments);
}
} else {
isInternal = true;
instance = new constructor(arguments);
isInternal = false;
return instance;
}
};
return constructor;
}
var MyClass = makeClassStrict();// create "class"
MyClass.prototype.init = function(employeeName, isWorking) {
var defaultName = 'notbob';
this.name = employeeName ? employeeName : defaultName;
this.working = !!isWorking;
this.internalValidate = function() {
return {
"check": this.working,
"who": this.name
};
};
};
MyClass.prototype.getName = function() {
return this.name
};
MyClass.prototype.protoValidate = function() {
return {
"check": this.working,
"who": this.name
};
};
var instanceBob = MyClass("Bob", true);// create instance
var instanceFred = MyClass("Fred", false);// create instance
var mything = instanceFred.internalValidate();// call instance function
console.log(mything.check + ":" + mything.who);
var myBobthing = instanceBob.protoValidate();
console.log(myBobthing.check + ":" + myBobthing.who);
