Step 3：Client modules backstage is automatic to obtain the page data of server module the 2nd, and client modules receive page 2
Data, and be buffered in local data cache module.Now the 1st page data is CurrentPage data, and the 2nd page data is
NextPage data；
Step 4：It is automatic in the afterbody of list when user's slide downward, and when will slide into the end of the 1st page data
Add the 2nd page data；
Step 5：When user formally slips down to 2 page data, client modules backstage obtains service end automatically again
The page data of module the 3rd.Now the 1st page data is PreviousPage data, and the 2nd page data is CurrentPage data,
3rd page data is NextPage data；
Step 6：So on, when user formally slips down to 3 page data, client modules backstage is automatic again
Obtain the page data of server module the 4th.Now the 2nd page data is PreviousPage data, and the 3rd page data is
CurrentPage data, the 4th page data are NextPage data；The downslide operation of user is performed by this rule.
Step 7：Now, if sliding operation in user's execution, when user will on slide into the top of the 3rd page data
When, PreviousPage data, namely the 2nd page data are automatically added on the head of list.
Step 8：When sliding into 2 page data on user is formal, client modules backstage is automatic to obtain server module the
1 page data.Now the data that the 1st page data is PreviousPage will be become again, the 2nd page data is CurrentPage number
According to the 3rd page data is NextPage data.
Further scheme is：
Local data cache module asks to access the page data of server module the 1st, or last page in client modules
During data, current page and NextPage data are only cached, or only caches current page and PreviousPage data, in visitor
When end module request in family accesses server module except the 1st page data and last page data, cache current page and
PreviousPage data, NextPage data totally 3 page data,
The current page is CurrentPage data.
Further scheme is：
Each page data is n bars, and n is greater than 1 natural number.
Further scheme is：
The data of described n bars can fill 2 to 3 hardware screens.
Further scheme is：
The preloaded list method does not limit the computer language of realization, can be C language, Java, JavaScript
Deng.
It should be noted that PreviousPage, CurrentPage, NextPage be intended merely to convenient narration and to this
The name or other titles of the 3 page datas life of ground caching, can't have a negative impact to technical scheme.
By the above method, just can rapid requests server data, be quickly presented to user, moreover it is possible to avoid internal memory from overflowing
Problem, realize that optimal user is experienced, allow the process of user's almost imperceptible data loading.
