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.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
