javascript - 在javascript中附加到json文件

Question

我有一个 json 文件 employees.json，我想将数据附加到该对象。该文件如下所示:

var txt = '{"employees":[' +
'{"firstName":"Jerry","lastName":"Negrell","time":"9:15 am","email":"jerry@bah.com","phone":"800-597-9405","image":"images/jerry.jpg" },' +
'{"firstName":"Ed","lastName":"Snide","time":"9:00 am","email":"edward@bah.com","phone":"800-597-9406","image":"images/ed.jpg" },' +
'{"firstName":"Pattabhi","lastName":"Nunn","time":"10:15 am","email":"pattabhi@bah.com","phone":"800-597-9407","image":"images/pattabhi.jpg" }'+
']}';

我想追加:

• 名字:迈克
• 姓氏:Rut
• 时间:上午 10:00
• 邮箱:rut@bah.com
• 电话:800-888-8888
• 图片:图片/mike.jpg

到 employee.json。

我将如何完成这个？

Answer 1

var data = JSON.parse(txt);  //parse the JSON
data.employees.push({        //add the employee
    firstName:"Mike",
    lastName:"Rut",
    time:"10:00 am",
    email:"rut@bah.com",
    phone:"800-888-8888",
    image:"images/mike.jpg"
});
txt = JSON.stringify(data);  //reserialize to JSON
