How Can I Remove A Single Parent From Firebase?

Question

In Firebase, there is a tree that holds data using parents, elements, and childs. Like so:

m3r945ba1lh -JTHUY9SMruiPaKW6-SW calendar: "2014-08-14" name: "apple" -JTHWE66v3E7NTuUidfM calendar: "" name: "hello" text: "10101" -JTHWFAYBxIZjOixh8ZZ calendar: "" name: "sos" text: "111"

I need to delete the data that is slanted, but one bolded data set at a time.

I have tried using myDataRef.remove(); but it deletes ALL data stored.

I have also tried $(this).parent().remove(); but it doesn't work at all

anybody know how to delete one at a time?

Do you want to remove the parents too, or just the data inside them? — Tom Hallam, Aug 01 '14 at 17:21
$(this) looks like jQuery. Not sure what that could be intending to accomplish. — Kato, Aug 01 '14 at 21:32

Query the root and remove the children by iterating through them.

var rootRef = new FireBase('https://your-url.firebase.com/');
    rootRef.once('value', function(snapshot){
       var children = snapshot.val();
       for(var child_id in children) {
            // Create a reference to it
            var child = rootRef.child(child_id);
            child.remove();
       }
    });

Rather than for(key in val) you should utilize snapshot.forEach(function(ss){ ss.ref().remove() }); – Kato Aug 01 '14 at 21:33
