Hello, I have a FireBase location with a few items, and ref is a FB reference to that location. I want to retrieve an item using
ref.$child(name) where 'name' is the key of an item in the FBlocation. If the item exists in the FB location, FB returns the item like this email "[email protected]" lastLogin "2014-02-25 22:01:26 +0100" md5_hash "2b764fcccac90624c7be4b5edf58f8b3" registryDate "2014-02-25 22:01:26 +0100" username "test user 1" $add function() $auth function() $bind function() $child function() $getIndex function() $off function() $on function() $remove function() $save function() $set function() $transaction If the item _doesn't_ exists in the FB location, FB returns the item like this email "[email protected]" $add function() $auth function() $bind function() $child function() $getIndex function() $off function() $on function() $remove function() $save function() $set function() $transaction So I figures, in order to know if the item exiosts in the FB location all I have to do is check for the existence of one of the keys lastLogin - lastLogin. But doing this: console.log(user.username) console.log(user.username==undefined) where user == the item that exists exists (so it is the first dump with te extra keys) returns undefined true How can I test if a ref.$child returned an existing item or a general object? -- You received this message because you are subscribed to the Google Groups "AngularJS" group.
