Assigning and adjusting the zoom ratio does not seem to work #30

Hello, I need help. I tried using the zoom percentage adjustment feature and it is not getting the new value received.

I followed the example: Wheelzoom (document.querySelectorAll ('img'), {zoom: 0.05});

I changed the value of 'zoom: 0.05' to other values like '0.05', '0.50', '10.00' and others ... did not make any difference.

I tested by adding a new default variable to test with an 'Alert' inside the script and also did not change the value:

Wheelzoom (document.querySelectorAll ('img'), {direction: 5});

And added the default variable:

_Window.wheelzoom = (function () { Var defaults = { Zoom: 0.10, MaxZoom: false, Direction: 1 };_

Alert only shows '1' and not 5 assigned.

What could be the problem? Or what can I be doing wrong? From now on, thank you very much for your contribution with this script, really very useful and has helped me a lot until now.

The fact that your direction value wasn't updated is fine and expected. The script isn't merging the whole defaults object into a new settings object, it's just looking at the values it actually uses (zoom and maxZoom).

I don't know why changing the zoom value didn't work. Since that's not something I can reproduce, it would help if you provided a link that demonstrates the problem.
