Can't access data from localStorage

In my content script I have done following :

document.onreadystatechange = function(){
  localStorage["options"] = "yes";
}

If I try to access this localStorage["options"] in my options.html page. it is giving me undefined error.

What can I do to access this content?

My Requirement : I need to get some data from the page source of a specific page and store it in localStorage. Then i need to process this data in my options.html page.

Edit : I am able to access the localStorage created in the options page in my background page. But I can't access localStorage created in content script in the options page.

Unfortunately, that's not a bug. You've hit a limitation in Chrome's extension sandboxing. Background and options pages don't share cookies, localStorage, or any other JS persistence that you would expect to work on the same "domain" (read: extension).

The solution is to use messaging, as described in the docs: Message Passing
