basic example of passing variable from popup to content script

[ppick...@acumensolutions.com]

Hi all,

I am new to chrome extensions and am having trouble with message passing. Does someone have a barebones example of passing a variable value from popup.js to background.js to contentscript.js? I am trying to toggle a feature on the content page by clicking a button in the popup. I would like to know what to include in each of the scripts as well as in the manifest (using V2). Specifically, how do I target the active tab? Thanks in advance!

Paul

You don't need to pass message between the popup and the background page. You can call a function in the backgound page from the popup by using the getBackgroundPage() function on chrome.extension like this:

var bgpage = chrome.extension.getBackgroundPage();

bgpage.someBackgroundPageFunction([SOME VARIABLE(S) FROM POPUP]).

As for background to content script google own page on this is perfectly easy to follow I think:

Thanks for that. A working example of at least background.js>contentscript.js would be much appreciated.
