_ Construct is the SubPages Constructor used to automatically run classes when they are created.
@ $ Each_disNums number of entries per page
@ Nums total number of entries

@ Sub_pages the number of pages displayed each time
@ SubPage_link: the link of each page

Normal paging mode when @ subPage_type = 1
Example: a total of 4523 records are displayed. 10 records are displayed on each page. Currently, page 1/453 [Homepage] [Previous Page] [Next Page] [last page]
Classic paging style when @ subPage_type = 2
Example: current page 1/453 [Homepage] [Previous Page] 1 2 3 4 5 6 7 8 9 10 [Next Page] [last page]
