Question

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….

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
