I am trying to display a tooltip under the mouse when mouse stays at a position long enough. I am using "absolute" positioning, set the tooltip as the child of the document.body, and set the style.left and style.top as event.clientX + document.body.scrollLeft and event.clientY + documentbody.scrollTop. Following is the related code:
tooltip.style.position = "absolute"; var x = event.clientX + document.body.scrollLeft; var y = event.clientY + document.body.scrollTop; tooltip.style.left = x + "px"; tooltip.style.top = y + "px"; document.body.appendChild(tooltip); But it does not work in a scrolled and zoomed page. (works fine in a scrolled page without zooming or zoomed page without scrolling). I think the (x, y) need to be adjusted by pageZoomFactor. But I did not find pageZoomFactor is exposed through JS. I tried to change the position to be "fixed" and hide the tooltip onMouseWheel/onMouseDown/onKeyDown event to comprise "fixed element does not scroll with the rest of the document", but I still could not find the right position value for the tooltip in case of scolled and zoomed page. Anyone has any idea how should I position the tooltip correctly in JS? Does pageZoomFactor has to be exposed in JS to make it work? Thanks, Xiaomei
