appending to json file in javascript

Question

I have a json file, employees.json, that I would like to append data to this object. The file looks like this:

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

I would like to append:

• firstName:Mike
• lastName:Rut
• time:10:00 am
• email:[email protected]
• phone:800-888-8888
• image:images/mike.jpg

to employee.json.

How would I accomplish this?

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:"[email protected]",
    phone:"800-888-8888",
    image:"images/mike.jpg"
});
txt = JSON.stringify(data);  //reserialize to JSON

Answer 2

JSON stands for Javascript object notation so this could simply be a javascript object

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

When you want to add an object you can simply do:

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