a simple problem about chrome extension. : )

I am a beginner with chrome extension. In my content开发者_如何学编程_script.js, how can a get an array in Javascript from background.html?

I did it like this: (assuming you have an array foo in background.html)

chrome.extension.getBackgroundPage().foo

But apparently, that only works for things like popup.html, etc. To get data from your background page in a content_script.js file, you need to use:

chrome.extension.connect()

The API docs are here.

you have to use message passing which I am finding a pain to use, but anyway details here
