add a per-listener latency settings

[benoitpointet]

I afterall need it.

Take http://benoit.pointet.info/stuff/jquery-scrollsnap-plugin/

The ideal latency for whole doc scrolling is different than the one for the "colored areas".

That means I need to set latency per listener.

Thanks,

Okay, I will take a look at your pull request again. Passing a data object per event listener is likely the way to go.

I added configuration data similar to your earlier pull request. You can supply per-element configuration by passing data when binding the events:

// Configure latency to 650ms for #scrolling-div
$("#scrolling-div").on("scrollstop", {latency: 650}, function() { ... });
