 下面两种选一种就可以了。


    <script>
        onmousemove = function (a) {
            document.getElementById('aa').value = a.x;
            document.getElementById('bb').value = a.y;
        };
    </script>
    

 

    

    <script>
        addEventListener("mousemove", function (a) {
            document.getElementById('aa').value = a.x;
            document.getElementById('bb').value = a.y;
        };
    </script>
