  • [Javascript] Can I not use while loops in functions?
    Try pasting your code into a validator to see if you don't have a typo somewhere: https://beautifytools.com/javascript-validator.php. Source: about 4 years ago
  • getting an error in Console, "Error in parsing value for โ€˜backgroundโ€™. Declaration dropped." don't know what am i doing wrong.
    So everything works fine the way I see it and that error only comes up after a few clicks. Since I'm not a js wizard I did put your script code into a javascript validator and it looks like you're missing a couple of semi colons here and there, maybe that'll fix it. Source: over 4 years ago
