HTML5: dragover(), drop(): how get current x,y coordinates?

The properties clientX and clientY should be set (in modern browsers): function drag_over(event) { console.log(event.clientX); console.log(event.clientY); event.preventDefault(); return false; } function drop(event) { console.log(event.clientX); console.log(event.clientY); event.preventDefault(); return false; } Here’s a (somewhat) practical example that works in Firefox and Chrome.
