testing here: https://perchance.org/z7l103ul1q#edit I have quite a big list of variables, that cause errors if undefined or null. So, I wanted to run a FOR through all of them at the very beginning. But perchance functions always ask to return something. How do I do it?
That’s what I’m doing. I’m setting those values to all html elements, as well as using them in the lists. That’s why I need to declare them to avoid “undefined” errors in the list section, for the first time users or after a remember(root, forget). Right now I have a long construction with something like this,
[actor==undefined?actor="Any":""], it’s clunky but it works. The “optimized” version that I was trying to make and asked help for withFORconstruction and window[key] =… actually worked but in the HTML part. You’re right it,THISof course, referred to the function not the document. However, while it works for the elements, somehow the lists “forget” them immediately after the first update(). So, I’m just keeping it as is for now with [if undefined then value].
