@jayarjo Thanks for your feedback! Yes, as you pointed out, there wasn't the procedure about preventing the navigation events in the previous polyfill. I updated the polyfill with https://github.com/WICG/spatial-navigation/pull/156, and now you can prevent the events.
You can see how it works in this demo.
@jihyerish great that there's progress on this! But do you actually reset those global flags back to initial value anywhere? Or they are not meant to?
@jayarjo Yes, the flags are used for defining the prevent default behavior for the navigation events. Those flags are set as true
when the events are triggered.
And if those flags are set as true
, in the processing model flows to the prevented behavior of the corresponding events.
For example, in the polyfill code line 316 -319, it follows the prevented behavior of navbeforescroll
.
if (!navbeforescrollPrevented) {
moveScroll(container, dir);
return true;
}
Is there a way to intercept nav events and prevent consequent logic from unfolding? Obviously one can intercept
keydown
, but that would be cumbersome, would be great if nav events themselves behaved similarly.
