(编辑：jimmy 日期: 2025/12/30 浏览：3 次 )
几种鼠标触发CSS事件。
说明：
onMouseDown 按下鼠标时触发
onMouseOver 鼠标经过时触发
onMouseUp 按下鼠标松开鼠标时触发
onMouseOut 鼠标移出时触发
onMouseMove 鼠标移动时触
复制代码 代码如下:
<html>
<head>
<title>CSS 鼠标响应事件</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<style type="text/css">
.Off{ background-color: #00FF66; padding:100px;}
.up{background-color: #FF0000; padding:100px}
</style>
</head>
<body>
<ul class=Off onMouseOut="this.className='Off'" onMouseOver="this.className='Up'">
<h4>鼠标响应事件 当鼠标经过移出时切换css</h4>
<li>onMouseDown 按下鼠标时触发
<li>onMouseOver 鼠标经过时触发
<li>onMouseUp 按下鼠标松开鼠标时触发
<li>onMouseOut 鼠标移出时触发
<li>onMouseMove 鼠标移动时触发 </li>
</ul>
</body>
</html>
复制代码 代码如下:
<span style="color: red;">鼠标经过表格变色样式:<br></span>
复制代码 代码如下:
<style>
table { background-color:#000000; cursor:hand; width:100%; }
td {
/*设置onmouseover事件*/
onmouseover: expression(onmouseover=function (){this.style.borderColor ='blue';this.style.color='red';this.style.backgroundColor ='yellow'});
/*设置onmouseout事件*/
onmouseout: expression(onmouseout=function (){this.style.borderColor='';this.style.color='';this.style.backgroundColor =''});
background-color:#ffffff;
}
</style>
控制表格隔行变色:
简单应用:
<style type="text/css">
<!--
tr {background-color:expression((this.sectionRowIndex%2==0)?"#E1F1F1":"#F0F0F0")}
-->
高级应用:每个单元格变色
<style type="text/css">
<!--
tr {background-color:expression((this.sectionRowIndex%2==0)?"red":"blue")}
td {background-color:expression((this.cellIndex%2==0)?"":((this.parentElement.sectionRowIndex%2==0)?"green":"yellow"))}
-->
</style>
添加CSS文件引用:
复制代码 代码如下:
<link id="cssStyle" rel="stylesheet" type="text/css" href="../style.css" />
说明：
onMouseDown 按下鼠标时触发
onMouseOver 鼠标经过时触发
onMouseUp 按下鼠标松开鼠标时触发
onMouseOut 鼠标移出时触发
