Chrome extension: messaging
Hey!
This is not a real extension, I'm just screwing around to see how this works.
Basically, in my background.html page I have this:
and in my popup.html page, I have this:
But the alert "Works" never seems to be called... I even tried to replace the
with
which in turn has an alert()... but that does not get called either.
Mind telling me where I went wrong? And giving me the code to make my little example work?
I even reversed the pages so that the code from background is in popup and the code from popup is in background... does not work :(
Thanks! R

chrome.extension.sendRequest('test2');

chrome.extension.onRequest.addListener(
function(request, sender, sendResponse) {
if(request.function == "test3") {
alert("Works!");
}
}
);
But the alert "Works" never seems to be called... I even tried to replace the
alert("Works!");
with
call_test_function();
which in turn has an alert()... but that does not get called either.
