一 介绍
利用position属性来显示隐藏着的<div>标签。当鼠标移动到指定目标时，显示出提示文字“自定义鼠标提示”。
二 代码
<script type="text/javascript">
function showTip(oEvent)
{
var oDiv = document.getElementById("divTip1");
oDiv.style.visibility = "visible";
oDiv.style.left = oEvent.clientX + 5;
oDiv.style.top = oEvent.clientY + 5;
}
function hideTip(oEvent)
{
var oDiv = document.getElementById("divTip1");
oDiv.style.visibility = "hidden";
}
</script>
<body>
<p>将鼠标移动到红色方框中</p>
<div id="div1"
style="background-color: red; height: 50px; width:50px" onmouseover="showTip(event) " onmouseout="hideTip(event)">
</div>
<div id="divTip1"
style="background-color: yellow; position: absolute; visibility: hidden; padding: 5px">
<span style="font-weight: bold">自定义鼠标提示</span>
</div>
</body>
