It should be done in the JavaScript itself. You might need to call b4j_raiseEvent to raise a server event from the "then" function.

it was simpler than i thought ?

js code:

ws.Eval($"getIPs().then(res => {b4j_raiseEvent("get_public_ip",{res});});"$,Null)

b4j event:

Sub get_public_ip(Params As Map)
    If Params.ContainsKey("res") Then 
        Dim l As List = Params.Get("res")
        For i = 0 To l.Size-1
            Log(l.Get(i))
        Next        
    End If
End Sub

public ip cdn:

You can make is simpler:

ws.Eval(...)
Wait For get_public_ip(Params As Map)
Log(Params)
