Hi, There’s no reliable way to do so as all requests arrive simultaneously on the server side, so unless you do a distributed lock — which is not a good idea usually — there’s no way to do so.
One of ideas is: you could pass sequential number with every request, put that number in a storage (like Redis) using compare and set, and if request is older than the one already in storage — do nothing. Usually such requests are throttled on the client side, I.e.: https://github.com/cowboy/jquery-throttle-debounce On Friday, June 7, 2019, Svein-Erik Løken <se.lo...@brav.com> wrote: > When typing "test" pretty fast into textfield id=nameFilter the result is > wrong.
