要在JavaScript中找到光标的坐标，请使用event.screenX和event.screenY。
您可以尝试运行以下代码来获取相对于JavaScript屏幕的光标坐标。
<!DOCTYPE html>
<html>
<head>
<script>
function coordinatesFunc(event) {
document.write("Coordinate(X) = " + event.screenX + "<br>Coordinate(Y) = " + event.screenY);
}
</script>
</head>
<body>
<div onmousedown = "coordinatesFunc(event)">Click me to get coordinates of cursor relative to screen.</p>
</body>
</html>
