How do I send data between files in a Chrome Extension/Website?

So, I have a chrome extension that does various things to a site. What I would like to do is rewrite it, to make it cleaner and more relevant, so I started. I have what content script, and it is 'infuse.js' which injects another file t3.js, into the website.

My question is - is there any way to pass data from localStorage to t3.js?

I have sendRequest and a response set up, so infuse.js can read the storage, but, if I try to do a sendRequest from t3.js, it obviously comes up as undefined as it isn't a content script, and thusly does not have access the API.

Let me know if you know anything.

There's something on this in the docs.... http://code.google.com/chrome/extensions/content_scripts.html#host-page-communication

Also, if you want to pass something to t3.js only once when its injected, then you can inject some js that sets some values, before injecting t3.js.

settings={1:"something'set'",2:["blek",1,2,3]}; //Youd get these from localStorage or something

head = document.getElementsByTagName('head')[0],
script = document.createElement('script');

script[script.innerText ? 'innerText' : 'textContent'] = 'var settings=' + JSON.stringify(settings)+ ';';

head.appendChild(script);

//Then inject t3.js
