Answer 1

This is not possible with localstorage. However, you can store a JSON string as the value for the key, and with a little post-processing, you can extract your three variables:

var value = ["aa","bb","cc"]
localStorage.setItem("testKey", JSON.stringify(value));
var test = JSON.parse(localStorage.getItem("testKey"));
alert(test);
