Conditional to detect an empty value attribute (attribute="")

Hello there,

Just wonder how can a "if" conditional can be used to detect the case where an attribute is empty (not null) like:

name="" fov="" width=""

Used to work with this one for single conditional but it's not working when mixed with other condition.

if(element[name].attribute == , then_action(););

AFAIK this is not the case for null attribute as in this case it's there but it just doesn't have any value.

Thanks in advance!

Just found the solution myself, post it here if anybody else needs it.

if(!element[name].attribute, then_action(););

That way it can be used aside other conditionals.
