mvc baseado no prototypejs

Recommended Posts

oias pips,

Vejam lá este exemplo de MVC baseado no prototypejs... fiz isto para organizar melhor o código no lado do cliente quando o javascript é enorme...

Já outros MVC javascript... gosto disto porque é simples embora falte a parte de error handling que voces podiam sugerir :thumbsup:

Digam o que se podia melhorar...

Exemplo...

Model.js:

var Model = Class.create({

initialize: function() {
	this.url	= 'service.php';
	this.parameters = {};
	this.method	= 'POST';
	this.headers	= { Accept: 'application/json' },
	this.transport	= {};
	this.format	= 'json';
},

call: function(cb) {
	new Ajax.Request(this.url,
		{
			method: this.method,
			requestHeaders: this.headers,
			parameters: this.parameters,
			onComplete: function(transport) {
				this.transport = transport;
				data = transport.responseJSON;
				if (this.format == 'text') data = transport.responseText;
				else if (this.format == 'xml') data = transport.responseXML;
				cb(data);
			},
			onFailure: function() {
				this.failure();
			}
		}
	);
},


failure: function() {
	alert('Failed!');
},

json: function() {
	return this.transport.responseJSON;
},

text: function() {
	return this.transport.responseText;
}

});

User.js

var User = Class.create(Model, {
initialize: function() {
	this.url	= 'service.php';
	this.parameters = {m: 'User'};
	this.method	= 'POST';
	this.headers	= { Accept: 'application/json' },
	this.transport	= {};
	this.format	= 'json';
},

readAll: function(cb) {
	this.parameters.f = 'all';
	this.call(cb);
},

readOne: function(id, cb) {
	this.parameters.f = 'one';
	this.parameters.id = id;
	this.call(cb);
}
});

Para as Views...

var ListView = Class.create({

initialize: function(elem, list) {
	this.elem = elem;
	this.list = list;
},

show: function() {
	var ul = new Element('ul');
	this.list.each(function(item) {
		ul.insert(new Element('li').insert(item.html));
	});
	$(this.elem).replace(ul);
}
});

var UserListView = Class.create(ListView, {

initialize: function(elem, list) {

	data = [];
	list.each(function(item) {
		item.html = item.name;
		data.push(item);
	});

	this.elem = elem;
	this.list = data;
}
});

e por fim um controlador...

var UserModel = new User();
UserModel.readAll(function(list) {
	this.UserView = new UserListView('app', list);
	this.UserView.show();
});

Podem ver um exemplo a funcionar aqui:
