通过这个 可以判断鼠标移动的情况。这样 你需要去监听 当前坐标的值 。
每几秒监听下值 是否变化，如果不变。
就用CSS样式
BODY{CURSOR: url('空白图片url')}
去把鼠标 换个图片。
用样式<style type="text/css">
BODY{CURSOR: url('http://www.baidu.com/favicon.ico')}
</style>
<DIV onmouseover="document.getElementById('abc').style.display = 'block'" onmouseout="document.getElementById('abc').style.display = 'none'">经过我这里
</DIV>
<DIV id="abc" onmouseover="this.style.display = 'block'" onmouseout="this.style.display = 'none'">
我本来是隐藏滴
</DIV>
