How can I set an Event type for 'layerX' and 'layerY'

问题

I'm making a dropdown menu having an absolute position. It gets x, y coordiation from mouse event.

container.addEventListener(
  'contextmenu',
    (e: MouseEvent) => {
      drawingMenuX = e.layerX + 15; // chartiq basic padding is 15
      drawingMenuY = e.layerY + 15;
    },
    false,
);

But it show error "Property 'layerX' does not exist on type 'MouseEvent'.ts(2339)". How can I set a correct event type instead of MouseEvent?

回答1:

As above @Daniel A.White said, it because layerX and layerY are non-standard. The alternative option is offsetX and offsetY.
