前一些天做项目的时候写了一个通用的OO By Class Cookie
今天把它放上来给大家分享下！
各位如果有更好的见解可讨论下！

测试JS DEMO
1 function testFn(){
2
3 var cookie = new Cookie('Test');
4
5 if(!cookie.name || !cookie.color){
6
7 cookie.name = prompt('What is your name:','');
8
9 cookie.color = prompt('What is your favorite color:','');

13 if(!cookie.visits) cookie.visits = 1;
14 else cookie.visits++;
15
16 cookie.store(10);
17
18 alert('color:' + cookie.color + ' name:' + cookie.name + ' visits:' + cookie.visits);
