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 = {
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>
