I translated this topic and I noticed that it is about some jQuery script that generates a related posts list.
I am afraid that this is OT in the Hugo forum.
Also a duplicate topic with the exact same content by @ed_edwin came up for moderation today and I rejected it.
@liliang8858 and @ed_edwin I kindly request that you read the Simple Code of Conduct for posting in the forum.
These rules apply even for Chinese language speakers.
Thank you.
