我想实现table row改变背景
我让让鼠标移动到table中的某一行时，这行的背景色或背景图片改变。
我在php里面就设置了onmouseover和onmouseout:
echo "<tr onmouseover='" . "setrcolor('1', '".$row['roomname'].")'";
echo "onmouseout='" . "setrcolor('0', '".$row['roomname'] . ")' >";
script部分如下：
function setrcolor(v,id)
{
if(v=="1")
{
document.getElementById(id).style.background="#fcf4f6";
alert("1");
}
if(v=="0")
{
document.getElementById(id).style.background="";
alert("0");
}
}
总是在setrcolor(这个地方报告语法错误，不知道为什么？
[解决办法]
一般这样处理：
- HTML code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title><script type="text/javascript">window.onload = function() { var obj = document.getElementById('demo').getElementsByTagName('tr'); for (var i = 0; i < obj.length; i ++) { obj[i].onmouseover = function() { this.style.backgroundColor = 'red'; } obj[i].onmouseout = function() { this.style.backgroundColor = ''; } }}</script></head><body><table width="500" border="1" id="demo"> <tr> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr></table></body></html>

- HTML code
<table width="500" border="1" id="demo" cellpadding="0" cellspacing="0"> <tr onmousemove="this.style.backgroundColor='red'" onmouseover="this.style.backgroundColor='red'" onmouseout="this.style.backgroundColor='#fff';"> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr></table>
