Firebase:更新密钥？

Question

{ 
    43268jfjn7983-347983:
    {
         title: 'hello world', 
         time: '1000'
    } 
}

如上所述,我只是想更新43268jfjn7983-347983到其他东西,这可能在firebase中吗？

Answer 1

无法更改现有节点的密钥.

所以相反,我会去:

var ref = new Firebase('https://my.firebaseio.com/');
var child = ref.child('43268jfjn7983-347983');
child.once('value', function(snapshot) {
  ref.child('somethingElse').set(snapshot.val());
  child.remove();
});
