Backbone model sample (javascript)

Following sample script demonstrates all Backbone.js libraray model related functions:

• attributes
• setting default values
• getting list of attributes
• constructor
• validation 
• methods
• converting to JSON

	Person = Backbone.Model.extend({
	// default values of attributes
	defaults:{
	age:0,
	children: []
	},
	// validation
	validate: function(attributes){
	if(attributes.age<0){
	console.log("Validation error, person can't be negative age!");
	return "person can't be negative age";
	}
	},
	// constructor method
	initialize: function(){
	console.log("New person was born");
	this.bind("error",function(model,error){
	console.log("ERROR:"+model);
	});
	// Listen to attribute changes (using bind)
	this.bind("change:name", function(){
	var currentName=this.get("name");
	console.log("Name changed from "+currentName + " to " + name);
	});
	},
	// custom methods
	adopt: function(newChildsName){
	var childrenArraya=this.get("children");
	childrenArraya.push(newChildsName);
	this.set({"children": childrenArraya});
	},
	replaceNameAttr: function(name){
	this.set({name: name});
	}
	});
	var person = new Person();
	person.set({name: "John", lastName:"Dove", children: ["First","Second"]});
	person.adopt("Tara");
	// validation is only run on save method or by turning on validate option on set method (since Backbone 0.9.10)
	person.set("age", -5 , {validate : true});
	this.person.save({age: -10});
	console.log("Hi, "+person.get("name")+" and "+person.get("children"));
	person.replaceNameAttr("Johny");
	// person.set({name: "Milan"});
	// convert to JSON
	console.log(person.toJSON());
	// show all attributes
	console.log(person.attributes);
