数组与字符串的相互转化

var bb = ["vvvv","mmmmmmmm"];
bb .toString()   // 转化为字符串
// 结果
vvvv,mmmmmmmm

var aa = [{"name":"lx","age":"13"},{"name":"张三","age":"200"}];
// 转化为字符串 （json）
alert(JSON.stringify(aa));
// 结果
[{"name":"lx","age":"13"},{"name":"张三","age":"200"}]
var s =" [{'id':1,'name':'Test1'},{'id':2,'name':'Test2'}]";
var myObject = eval('(' + s + ')');
alert(JSON.stringify(myObject));
