This is basically just a JavaScript design, you can use apply/call to let
the function return what you need, for instance:
popup.html:
> var bkg = chrome.extension.getBackgroundPage();
bkg.test(function(result) {
alert(result);
});
background.html:
> function test(func) {
func.apply(this, ['bar']);
}
If you don't like to send an array of parameters you can use call to call
the args individually.
background.html:
> function test(func) {
func.call(this, 'bar');
}
You should see an alert. For more information, refer to
