Flex4将对象转换成json串

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");
