Disable / Enable Chrome Extension Via Browser Action / Icon

rated 0 times [ 41] [ 7] / answers: 1 / hits: 25559 / 11 Years ago, wed, september 11, 2013, 12:00:00

The chrome extension I am developing inserts content scripts and css onto every page of a website. However, the user may have a certain page or pages he or she does not want the extension to run on, so it would be great if I could set up the browser action as basically a toggle on / off.

What I'd like to do is something like this:

chrome.browserAction.onClicked.addListener(function(tab) {



    //IF ENABLED THEN DISABLE



    //IF DISABLED THEN ENABLE



}

Any help would be greatly appreciated!

Such API is not provided. But two possible workarounds exist:

I. You can use the "disabled" flag variable and update it from your background page.

Background page:

function disableExtension(disabled)

{

    chrome.windows.getAll({populate : true}, function (window_list)

    {

        for (var i = 0; i < window_list.length; ++i)

        {

            var window = window_list[i];

            for (var j = 0; j < window.tabs.length; ++j)

            {

                var tab = window.tabs[j];

                if (checkContentScriptExists(tab))

                {

                    chrome.tabs.executeScript(tab.id, {code : "disabled = " + disabled + ";"}, allTabs: true) 

                }

            }

        }

        // No matching url found. Open it in the new tab

        chrome.tabs.create({ url : url, selected: true });

    });

}

And content script should check the condition before the run

if (!disabled) doSomething();

II. A controversial approach to save disable variable within background page content

Background page:

function disableExtension(disabled)

{

    global.disabled = disabled;

}

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {

    if (request.msg == "getDisabled") {

        sendResponse({disabled: global.disabled});

        return true;

    }

});

and the content script should query currently disabled status before execution

chrome.runtime.sendMessage({msg: "getDisabled"}, function(response) {

   if (!response.disabled) doSomething();

});
