how do I read localstorage data stored in database

[Maurice Waka]

with this code:

js(view)

$('#timed').change(function(){  
        arr.push($(this).val());
        var arrayJSON = JSON.stringify(arr);
        localStorage.setItem("tabledata",arrayJSON);

controller

value =request.vars.json
if valued:
    db.post.insert(message=value)

My data is stored as 

<Storage {'json': '{"list":"[\\"sure\\",\\"<39\\",\\"unconfirmed_pcr\\"]"}'}>

how can I read a clean list like:

["sure","<39","unconfirmed_pcr"] or ["sure,<39,unconfirmed_pcr"]

Currently i'm using n.replace(). Is there a better, faster way?

Kind regards
