I've rendered a d3 map that has pan and zoom enabled, but when scrolling down the viewport either on desktop or mobile, the window gets stuck zooming in the map.
Is there a way to temporarily disable d3.zoom, while the window is scrolling?
I've seen ways of toggling the zoom/pan using a button as seen here: http://jsfiddle.net/0xncswrk/, but I wanted to know if it's possible without having to add a button. Here's my current zoom logic.
Thanks!
this.zoom = d3.zoom()
.scaleExtent([1, 8])
.on('zoom', () => {
this.svg.attr('transform', d3.event.transform);
});
this.svg = d3.select(this.el).append('svg')
.attr('width', '100%')
.attr('height', this.height)
.attr('class', 'bubble-map__svg-us')
.call(this.zoom)
.append('g');
EDIT: Wow old answer but never saw your comment. Sorry about that. Yeah sorry I forgot to consider mobile zooming.
In the documentation, perhaps this is new, but they recommend having more granular control of what zoom you allow by using zoom.filter. For touch related events, they also support zoom.touchable.
As specified in the d3-zoom documentation
To disable just wheel-driven zooming (say to not interfere with native scrolling), you can remove the zoom behavior’s wheel event listener after applying the zoom behavior to the selection:
selection
.call(zoom)
.on("wheel.zoom", null);
You can also consider just setting the scaleExtent to be [1,1] especially if it's just temporary so it locks the zoom to only one possible scale but preferably you opt for what the documentation says :P
