1、核心代码:
当鼠标移动到表格的某一行的时候为红色,鼠标移走的时候为白色。
<script> function changeColor(id,flag){ if(flag=="over"){ document.getElementById(id).style.backgroundColor="red"; }else if(flag=="out"){ document.getElementById(id).style.backgroundColor="white"; } } </script>
当时用某一行的时候,需要向函数中传递参数,即:表格的行位置和鼠标的状态。
<tr onmouseover="changeColor(‘tr1‘,‘over‘)" id="tr1" onmouseout="changeColor(‘tr1‘,‘out‘)"> <td align="middle ">1</td> <td align="middle ">20100300201</td> <td align="middle ">张小丽</td> <td align="middle ">95</td> <td align="middle ">95</td> <td align="middle ">95</td> </tr>
