Storing data like a cookie?

[KeirMeDear]

How would you go about holding data in a P5 sketch online if someone came back to it later.

For example, if I had a piece of code where you can choose the fill color of a rect, how could you make it store that value so if you closed the sketch and opened it again it would still be the last fill color you chose.

I understand in processing this would be easier as you could store the value in a text file between uses, but seeing as p5 is web based I’m not sure how to go about it and there doesn’t seem to be anything in the documentation.

Many thanks in advance

Creating and Populating a Table From Scratch

I’ve made a sketch that stores and reads an array of CSV row strings from the browser’s local storage using storeItem() & getItem() respectively; then converts that array to p5.TableRow objects; and finally use p5.Table::addRow() to populate a p5.Table container: http://p5js.org/reference/#/p5/getItem http://p5js.org/reference/#/p5.Table/addRow Each mouse click adds a new p5.TableRow to the p5.Table container, updating the browser’s local storage as well. …

Ah, getItem() and storeItem() sound perfect, didn’t realise it would be so easy to do

Many thanks as always g2l
