Thanks bob, I guess it's been about 8 years. Good to talk to you again.
Tricky. I suppose you would run into this pretty much any time you pass
around foo.bar when bar bound (or not) to the object foo as you wouldn't be
able to do the "call with this" syntax. If your blog post is right then it
looks like the only way to do "call with this" explicitly calling the
function via the object in code.
Anyway, changing the test code to
test.init = function() {
createLoggingPane(true);
callLater(3.0, bind(test.myfunc, test));
}
works. It's cute how bind returns a function that calls your function but
goes out and finds the "this" for you first. Pretty useful hack.
