This is related to another question I posted about being able to distinguish between 2 browser tabs. I saw your response that web2py cannot distinguish between the 2 (I'm assuming this happens because session is shared).
I as told that using HTML5 sessionStorage https://www.w3schools.com/html/html5_webstorage.asp it would be possible. What the code above is doing is creating a random number per tab and storing it in the sessionStorage, it also is stored in the hidden HTML input field. Now I just need a way to get the value stored in the hidden HTML input field and save it to a web2py's session dict var. sábado, 13 de Abril de 2019 às 16:28:15 UTC+1, Massimo Di Pierro escreveu: > > You cannot do whet you ask because a line like this: > > {{session[str(random_number)] = random_number}} > > would be executed by the server before the code is sent to the client and > before the js is executed by the client. > > What is the purpose?
