记录一下，一般使用JSON序列化一个对象成字符串描述时都比较难于阅读，特别是大量且复杂的数据时，如：

1 var s:String = '{"title":"Adobe Flash 11 Stage3D (Molehill)Game Programming","authors":["Christer Kaitila"],"edition":1,"year":2011}';
2 var o:Object = JSON.parse(s);
3 trace(JSON.stringify(o));

得到：

1 {"title":"Adobe Flash 11 Stage3D (Molehill)Game Programming","year":2011,"edition":1,"authors":["Christer Kaitila"]}

我们可以操作第3个参数实现格式化一般可以用下面的两者写法：

1 var s:String = '{"title":"Adobe Flash 11 Stage3D (Molehill)Game Programming","authors":["Christer Kaitila"],"edition":1,"year":2011}';
2 var o:Object = JSON.parse(s);
3 trace(JSON.stringify(o, null, "\t"));

得到：

1 {
2     "title": "Adobe Flash 11 Stage3D (Molehill)Game Programming",
3     "year": 2011,
4     "edition": 1,
5     "authors": [
6         "Christer Kaitila"
7     ]
8 }

或者：

1 var s:String = '{"title":"Adobe Flash 11 Stage3D (Molehill)Game Programming","authors":["Christer Kaitila"],"edition":1,"year":2011}';
2 var o:Object = JSON.parse(s);
3 trace(JSON.stringify(o, null, 4));

得到：

1 {
2     "title": "Adobe Flash 11 Stage3D (Molehill)Game Programming",
3     "year": 2011,
4     "edition": 1,
5     "authors": [
6         "Christer Kaitila"
7     ]
8 }
