使用json需要先引入as3corelib.swc

 

1、将对象转换成json串

var obj:Object = new Object();obj.filename = "1.jpg";obj.filetype = "image";obj.fileext = "jpg";var str = JSON.encode(obj);Alert.show(str,"标题");

 

2、将数组转换成json串

var arr:Array = new Array();var obj:Object = new Object();obj.filename = "1.jpg";obj.filetype = "image";obj.fileext = "jpg";arr.push(obj);                obj = new Object();obj.filename = "1.jpg";obj.filetype = "image";obj.fileext = "jpg";arr.push(obj);var str = JSON.encode(arr);Alert.show(str,"标题");
