I wanted to transfer an array from server side PHP to client side jQuery in metadata, as following:
...
$meta = metadata(array('invalid_chars' => $this->getUnwantedCharCodeArray()));
return sprintf('<div class="token %s">%s</div>', $meta, $output);
...
While in this way what I got at client side is an object, which could not be used in method like $.inArray():
$('.token').metadata().invalid_chars was an object like object { 0=35, 1=94....}, what I wanted was an array [35, 94...]
Tried .toArray() and $.makeArray(), wouldn't work....
Finally I found a solution: json_encode at the server side and parseJSON at the client side:
Server side:
...
$meta = metadata(array('invalid_chars' => json_encode($this->getUnwantedCharCodeArray())));
return sprintf('<div class="token %s">%s</div>', $meta, $output);
...
Client side:
if ($.inArray(charCode, $.parseJSON($('.token').metadata().invalid_chars)) > -1 ) { ...
