Question

Perhaps I’m missing something major, but is there a way to use Object.watch() on variables that exist independent of objects?

I’m a bit new to JS, and couldn’t find any kind of global object that my variable was attached to.

(Also, just using this for debugging, so the fact that it’s only supported in Mozilla browsers isn’t a problem.)

Answer 1

The global scope in a browser is actually the window object, so if your variable is a global variable, it’s actually attached to the window object. So you can access it as window.variableName just as well as simply variableName. And thus you should be able to say:

window.watch('variableName', callback);
