- json字符串----->json对象
-
使用JSON.parse()函数
var jsonStr = ‘{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}‘; var json = JSON.parse(jsonStr); console.log(json);//输出:Object {name: "zhangsan", age: 23, email: "chentging@aliyun.com"} -
使用eval()函数
var jsonStr = ‘{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}‘; var json = eval ("(" + jsonStr + ")"); console.log(json);//输出:Object {name: "zhangsan", age: 23, email: "chentging@aliyun.com"} -
使用jQuery插件jQuery.parseJSON()
var jsonStr = ‘{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}‘; var json = jQuery.parseJSON(jsonStr); console.log(json);//输出:Object {name: "zhangsan", age: 23, email: "chentging@aliyun.com"}
-
- json对象------>json字符串
-
使用JSON.stringify()
var json = {name: "zhangsan", age: 23, email: "chentging@aliyun.com"}; var jsonStr = JSON.stringify(json); console.log(jsonStr);//输出:"{"name":"zhangsan","age":23,"email":"chentging@aliyun.com"}" - 把数据在前后端之间传递，需要把json对象转换为json字符串
