setInterval, this, again

Question

I have a problem in regard to setInterval that I can\'t figure out.

There is the problem with the scope when calling setInterval or timeout fro

Answer 1

By the time setTimeout() gets around to call your method, it only sees the function and not the invocation context (i.e. the object to bind it to); much like this:

var bing = ships[i].bing;

bing(); // inside bing(), this == window

Basically, you need to provide setTimeout() with a prewired method invocation:

var bound_bing = ships[i].bing.bind(ships[i]);
timeoutID2 = setTimeout(bound_bing, 1000);

The "magic" happens with .bind() as it returns a new function that will have this set up properly.
