backbone.js - how and when to show a spinner

Question

Is there any sort of hooks in backbone where I can easily say "whenever any of the collections is fetching data, show the spinner, hide it when they're done"?

I have a feeling it will be more complicated than that and require overwriting specific functions. When should I show the spinner? On fetch() or refresh() or something else?

Answer 1

You can use jQuery ajaxStart and ajaxStop. Those will globally run when an ajax request is made, so fetch and save will cause those to run. Add your code to show the spinner in the start and hide it in the end.
