Hi Viniclus,
You can save several figures into a key by concatenating them together
into a string with a delimiter of your choice:
var str = "figure1, figure2, figure3, figure4";
and when recovering it, you need to use JS split function to break it
apart like this:
var pattern = /,/;
result = str.split(pattern);
However, our best practices RECOMMEND that you put all of the values
into a JavaScript object or array and use gadgets.json.stringify to
turn this structure into a JSON encoded string. Then you can simply
pull this string out of persistence, call gadgets.json.parse, and not
worry about the string parsing at all. We have sample persistence
code snippet like this on code.google.com.
Hope this helps!
