将动态数据保存在html5中的localstorage中？

Question

In my mobile app (jquery mobile + phonegap), I have two select menus and when user select some options from that menus, I want to store that in local storage. I know the simple syntax of local storage like localStorage.setItem(key,value); But i have no idea how to store dynamic data in local storage?

Answer 1

Dynamic meaning what?

For it to be "dynamic" then just update the localStorage item by running localStorage.setItem(key,value) using the same key and updating the value.

Make a function which gets all of the menus items and values (off or on, 0 or 1, false or true, or some string/integer) which runs localStorage.setItem(key,value) then call that function every time the menu is saved or updated.
