在javascript中附加json文件

Question

我有一個json文件employees.json，我想將數據追加到此對象。 該文件是這樣的：

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：

• 姓：邁克
• 名字：車轍
• 時間：10：00
• 電子郵件：車轍@ bah.com
• 電話：800-888-8888
• image：images/mike。 jpg

to employee.json。

我該如何做到這一點？

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 

Answer 2

JSON代表JavaScript對象符號所以這可能僅僅是一個JavaScript對象

var obj = {employees:[ 
    { 
     firstname:"jerry" 
     ... and so on ... 
    } 
]}; 

當你想添加一個對象，你可以簡單地做：

object.employees.push({ 
    firstname: "Mike", 
    lastName: "rut" 
    ... and so on .... 
});
