javascript - Setting up localStorage -

how can store multiple data in localstorage? using array doesn't seem work.

for(i=0;i<8;i++){    localstorage.vals[i]= item[i]; //vals[i] not work } 

use setitem() , getitem() methods of localstorage.

set object in localstorage.

var data = {}; (i = 0; < 8; i++) {     data[vals[i]] = item[i]; } localstorage.setitem('mydata', json.stringify(data)); 

to get it:

var mydata = json.parse(localstorage.getitem('mydata')); 

update

to check if data exists in localstorage:

if (localstorage.getitem('mydata')) {     // exists }
