1For storing array inside cookie :
2-----------------------------------
3setter : var json_str = JSON.stringify(arr); cookie.set('mycookie', json_str);
4getter : cookie.get('mycookie'); var arr = JSON.parse(json_str);
5----------------------------------------------------------------------------
6Function common for all type of variable :
7==========================================
8let cookie = {
9 set: function(name, value) {
10 document.cookie = name+"="+value;
11 },
12 get: function(name) {
13 let nameEQ = name + "=";
14 let ca = document.cookie.split(';');
15 for( let i = 0; i < ca.length; i++ ) {
16 let c = ca[i];
17 while (c.charAt(0)==' ') c = c.substring(1,c.length);
18 if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
19 }
20 return null;
