40. Prototype
Criar uma class – (sem o Class.create())
var myClass = function() {
this.init(); var myClass = {
}; init: function(name) {
myClass.prototype = { this.foo();
},
init: function() {
foo: function(arg) {
this.foo();
alert('Hello!');
},
}
foo: function() {
};
alert('Hello!');
} myClass.init(); /* Hello! */
};
new myClass(); /* Hello! */

41. Prototype
bind()
var myClass = function() { var myClass = function(name) {
this.init(); this.init(name);
}; };
myClass.prototype = { myClass.prototype = {
init: function() { init: function(name) {
setTimeout(function(){ setTimeout(function(bar){
this.foo(); this.foo(bar);
}.bind(this), 1000); }.bind(this, name), 1000);
}, },
foo: function() { foo: function(arg) {
alert('Hello!'); alert('Hello '+arg);
} }
}; };
new myClass(); /* Hello! */ new myClass('Gamboa'); /* Hello Gamboa*/

42. Prototype
bindAsEventListener()
var myClass = function(elm) { this.init(elm); };
myClass.prototype = {
init: function(elm) {
this.name = 'claudio';
Event.observe(elm, 'click', this.foo.bindAsEventListener(this));
//Event.observe(elm, 'click', this.foo.bindAsEventListener(this, 'gamboa'));
},
foo: function(e) {
alert('Hello '+this.name);
// alert('Hello '+this.name+' '+arguments[1]);
}
};
<a id=”mylink” href=”http://www.sapo.pt/”>sapo.pt</a>
new myClass(document.getElementById('mylink'));
clica-se e............ /* Hello claudio / ou /* Hello claudio gamboa */

43. Chega de Prototype

44. Vamos falar de jQuery?

As variáveis e o código...
var SAPO
SAPO.namespace();
SAPO.Browser //{version:'', isGecko:'', isIE:'', ...}
Apenas...
SAPO

47. LibSAPO.js
Ex: SAPO.Utility.String

<script type=”text/javascript” src=”http://js.sapo.pt/SAPO/”></script>
SAPO.namespace('Utility');
SAPO.Utility.String = {
trim: function(str) {
if (str && typeof(str) == 'string') {
return str.replace(/^s+|s+$|n+$/g, '');
}
}
};
var strTrim = SAPO.Utility.String.trim(' Sane eiusdem concilii patres ');
alert('|'+strTrim+'|'); /* |Sane eiusdem concilii patres| */

48. LibSAPO.js
Ex: SAPO.Widget.LameWidget

SAPO.namespace('Widget');
var SAPO.Widget.LameWidget = function(options) { this.init(options); };
SAPO.Widget.LameWidget.prototype = {
init: function(options) {
var options = Object.extend({
name: false
}, arguments[0] || {});
this.options = options;
this.foo();
},
foo: function() {
alert(this.options.name);
}
};
new SAPO.Widget.LameWidget({name:'gamboa'}); /* gamboa */
