Thanks for your comments.
Here is the source:

And here is some instructions... I have to admit this plugin is not
user-friendly :p
1. Every post’s container must have an ID named “entry-{$slug}”. If
you are sure you won't write any post which slug is begin with
“entry-” or “page-”, then you can simply named it “{$slug}”.
2. Every post must have an identical CSS class, e.g. “entry”, and this
CSS class must not appear elsewhere. You have to put this in “Class
name of posts”.
3. The page selector’s container must have an ID, e.g. “pager”. You
have to put this in “ID of page selector”.
4. You can put custom ‘pageless.php’ in the activated theme directory.
The plugin will use this template instead of the default one.
