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

JSON stands for Javascript object notation so this could simply be a javascript object
JSON 代表 Javascript 对象表示法，因此这可能只是一个 javascript 对象
var obj = {employees:[
{
firstname:"jerry"
... and so on ...
}
]};
When you want to add an object you can simply do:
当您想添加一个对象时，您可以简单地执行以下操作：
object.employees.push({
firstname: "Mike",
lastName: "rut"
... and so on ....
});
