字符串 数组 相互转化

数组转字符串

var a =[1,2,3]

b = a.join(",");

字符串转数组

vars = "abc,abcd,aaa";

ss = s.split(",");// 在每个逗号(,)处进行分解。

json字符串----->json对象

(1) var jsonStr = '{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}';var json =JSON.parse(jsonStr);

(2) var jsonStr = '{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}';var json = eval ("(" + jsonStr +")");

json对象------>json字符串

var json = {name:"zhangsan",age:23,email:"chentging@aliyun.com"};

var jsonStr = JSON.stringify(json);
