How can I extract only the node information that I select in firebase? EXAMPLE:

-L-qKQ-UICkQ1K-QAJDx
name: 'Jesus'
-L-qKRq1_yZmTdjvRqfN
name: 'Moises'

I just want to extract the node '-L-qKRq1_yZmTdjvRqfN' where the name 'Moises' is

Is there any way without having to select all?

firebase.database().ref('usuarios').on('value', function(data) {
    var element = data.val();
    $.each(element, function(nodo, value) {
        if(nodo == '-L-qKRq1_yZmTdjvRqfN') console.log(value.name);
    });
});

You can do that using the equalTo

function

firebase.database().ref('usuarios').orderByChild('name').equalTo('Moises').on('child_added', function(data) {
    var element = data.val();
    console.log(element.name);
});

Keep in mind that you can only use one condition (you can not put 2 equalTo in the same query).
