1.创建特定类型的对象

2.js开发尽量用单引号

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
		<title></title>
		<script>
			var AA = {
				/*构建者模式就是 构造对象自己*/
				Constractor: function(huawen) {
					//先自己实例化对象 ，function中的函数指向的是function,不是外层字典。
					if(!(this instanceof AA.Constractor)){
						return new AA.Constractor();
					}
					var me = this;
					me.huawen = "无";
					if (huawen != undefined || huawen != null)
						me.huawen = huawen;
					me.suo = "小锁";
					me.create = function() {
						return "花纹:" + me.huawen + "锁" + me.suo;
					}
				}
			}
			console.log(AA);
			var p =  AA.Constractor("有花纹");
			alert(p.create());
		</script>
	</head>

	<body>
