JS Common design Pattern (14)--Memo mode

Memo mode is often used for data caching in JS. For example, a paging control, from the server to obtain a page of data can be stored in the cache. When you turn this page back on, you can directly use the data in the cache without having to request the server again.

Implementation is relatively simple, pseudo-code:

varPage =function(){    varpage = 1, the cache={}, data; return function(page) {if(cache[page]) {Data=cache[page];       Render (data); }Else{ajax.send (' Cgi.xx.com/xxx ',function(data) {cache[page]=data;                Render (data); })       }     } }()
