How to exit in a loop of object in Firebase after a certain condition. I tried using return false but it doesn't work. Can someone help me. Thanks in advance.
Here is my code:
function checkRoom(room_id,user_id,other_user){
var dbRefObject = firebase.database().ref('chat-list');
//getting all keys
dbRefObject.on('child_added', function (snap) {
if(snap.key == 1){
//if condition succeed the loop will exit
return false; //but return false is not working here.
}
});
}
To break out of a snapshot's forEach iteration, you need to return true.
The forEach method's action parameter is:
A function that will be called for each child DataSnapshot. The callback can return
trueto cancel further enumeration.
Note that you can break out of the iteration by returning any truthy value - not just true.
