js得到鼠标位置

document.addEventListener('mousemove', function(event) {
    var mouseX = event.clientX; // 鼠标相对于浏览器窗口可视区域的X坐标
    var mouseY = event.clientY; // 鼠标相对于浏览器窗口可视区域的Y坐标

    console.log('Mouse X: ' + mouseX + ', Mouse Y: ' + mouseY);
});

document.addEventListener('mousemove', function(event) {
    var mouseX, mouseY;
    if (event.clientX || event.clientX === 0) {
        // 主流浏览器
        mouseX = event.clientX;
        mouseY = event.clientY;
    } else if (event.offsetX || event.offsetX === 0) {
        // IE8及以下
        mouseX = event.offsetX;
        mouseY = event.offsetY;
    }

    console.log('Mouse X: ' + mouseX + ', Mouse Y: ' + mouseY);
});
