js面向对象实例

function User() {
			var name = 'username';
			var password = 'password';
			//持有对象的this用于内部方法间调用
			var $this = User.prototype;
			$this.setName = function(_name) {
				name = _name;
			};
			$this.getName = function() {
				return name;
			};
			$this.setPassword = function(_password) {
				password = _password;
			};
			$this.getPassword = function() {
				return password;
			};
			$this.getUser = function() {
				alert($this.getName() + $this.getPassword());
			};
		}
		var user = new User();
		user.getUser();
