javascript - Using a variable inside document.getElementById -


i'd use php variable instead of #particles in below given code.

i tried using:

$(" . json_encode($paramnameid) . ").particleground({

but didn't work.

$script = "<script type='text/javascript'>        document.addeventlistener('domcontentloaded', function () {                  particleground(document.getelementbyid('#particles'), {                 dotcolor: " . json_encode($dotcolor) . ",                 linecolor: " . json_encode($linecolor) . "                   });                }, false);            </script>";

how can this?
