D3JS：滚动时向下调整图表大小

Question

I have this code which makes a chart to be responsive to all screen sizes and dimensions. the problem is that mobile browsers hide the 'url' bar when scrolling down and show it when scrolling up (when the top is reached), making the screen's height smaller or bigger

This causes the resize function , which resizes the chart every time the browser's dimensions change, to be triggered, and that's an unwanted behavior. Can you help me figure out how to solve this? I cant discard the resize function, because the chart wouldn't be responsive, and I have no idea how to deal with the URL field hidding and showing.

I'm leaving this running snippet so that you can see what's going.

Thak you so much.

Answer 1

add a "scroll" event handler and like the multiple "resize" event detection determine if there is a scroll event close to a resize event and cancel the resize. It depends who is triggered first in sequence.
