JavaScript+CSS+DIV实现表格变色

  • Post author:

设置一个表格,当鼠标移动到某行时,颜色改变,鼠标离开时,颜色变为原来的样子。每一行都要两个鼠标事件:


1.鼠标覆盖:onMouseOver


2.鼠标离开:onMouseOut


同时这两个事件需要调用事件函数:


1.实现对行的颜色设置:


resetColor(row)


2.实现对行颜色的改变:


changeColor(row)




实现代码:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">
<html>
  <head>
    <title>变色表格示例</title>
	<script type="text/javascript">
	function changeColor(row){
	 document.getElementById(row).style.backgroundColor='#9999FF';
	}
	function resetColor(row){
	document.getElementById(row).style.backgroundColor='';
	}
	</script>
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="this is my page">
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    
    <!--<link rel="stylesheet" type="text/css" href="./styles.css">-->

  </head>
  
  <body>
  <table width="200" border="1" cellspacing="1" cellpadding="1" align="center">
  <tr><th>学校</th><th>专业</th><th>人数</th></tr>
  <tr align="center" id="row1" onMouseOver="changeColor('row1')"
   onMouseOut="resetColor('row1')">
   <th>北大</th><th>法律</th><th>2000</th>
   </tr>
   <tr align="center" id="row2" onMouseOver="changeColor('row2')"
    onMouseOut="resetColor('row2')">
    <th>清华</th><th>计算机</th><th>5000</th>
   </tr>
   <tr align="center" id="row3" onMouseOver="changeColor('row3')"
    onMouseOut="resetColor('row3')">
    <th>人大</th><th>经济</th><th>6000</th>
    </tr>
  </table>
  </body>
</html>
