JS-CookGetSet

A simple JavaScript function; variable setter/getter in HTML5 localStorage with cookie fallback. Can be used to save variables of various object types between sessions.

Usage:

cookset(key_name, key_value) --> returns key_value, and sets a key/value pair in localStorage, or as a cookie if unsupported.
cookset(key_name, null) --> returns null, and deletes the pair.
cookget(key_name) --> returns key_value, or null if not set.

Example #1

Batch save/load variables in a session

var vars = {variable1, variable2, ...};
vars = Object.keys(vars);

function save() {
for (var i in vars) cookset(vars[i], window[vars[i]]);
cookset("saved",1);
}

function load() {
if (cookget("saved")) for (var i in vars) window[vars[i]] = cookget(vars[i]);
}

_{*Note, I use "$_" as an arbitrary unique prefix to key_name. You can change or delete this in the code to your liking.}
