I want to remove element from firebase using javascript

Question

I'm trying to understand how to remove an item from my Firebase. I've set up a function (saveEmployee) to create an item , but can't figure out how to go about removing an item.

HTML

<tbody ng-repeat="employee in employees"> 
            <tr>
                <td>{{employee.employeeName}}</td>
                <td>{{employee.employeeAge}}</td>
                <td><a class="btn btn-danger" ng-click="removeEmployee(employee.employeeName)" >Delete</a></td>
            </tr>
        </tbody>

JS

$scope.removeEmployee = function(employeeName) {
        console.log(employeeName);
        $scope.myData.child(employeeName).remove();
    };

Answer 1

Use Firebase.set() and pass in null. This will delete the employee.

$scope.removeEmployee = function(employeeId) {
   var employeeRef = new Firebase('https://myfirebaseurl.firebaseio.com/employees/' + employeeId);
   employeeRef.set(null);
};

or with a callback handler.

$scope.removeEmployee = function(employeeId) {
   var employeeRef = new Firebase('https://myfirebaseurl.firebaseio.com/employees/' + employeeId);
   employeeRef.set(null, function(error) {
       if (error) {
           console.log(error);
       } else {
           console.log('Employee deleted.');
       }
   });
};
