javascript - Check for completion on the firebase js .forEach method? -
i know there's completion handler .set
, .update
, wondering if there .foreach
.
for example, this:
firebase.database().ref().child('kid').orderbychild('date').on('value', function(snapshot) { snapshot.foreach(function(kid) { }, function(error) { //this error thrown } });
if isn't possible, there workaround? need function call once .foreach
method done running.
p.s. function stated in file, call normally.
no, synchronous javascript function. add line after function.
