You could write a javascript function to get an employee by id from a list of employees:

function getEmployee(id, employees) {
    for (var i = 0; i < employees.length; i++) {
        var employee = employees[i];
        if (employee.id === id) {
            return employee;
        }
    }

    return null;
}

and then use this function on the response you got from the server after parsing the JSON string back to a javascript object:

var json = 'the JSON string you got from the server';
var obj = JSON.parse(json);
var employees = obj.employees;
var employee = getEmployee(34, employees);
if (employee != null) {
    alert(employee.name);
}
