objTR.attachEvent("onMouseOver", fover);
objTR.attachEvent("onMouseOut", fout);
function fover()
{
event.srcElement.bgColor = "red";
}function fout()
{
event.srcElement.bgColor = "blue";
}
<style type="text/css">
.over{background-color:#FF0000}
.out{background-color:#0000FF}
</style>
<body >
<table id="vTable" width=895 border=1>
<table>
<script language="javascript">
function add()
{
col=vTable.rows.length
var vTr=vTable.insertRow(col)
vTr.className="out";
vTr.align="center";
vTr.attachEvent("onmouseover", function(){vTr.className='over'});
vTr.attachEvent("onmouseout", function(){vTr.className='out'});
for(i=0;i<4;i++)
{
vTd=vTr.insertCell(i);
vTd.innerHTML=i
}
}
add()
</script>
<input type="button" value="添加" onclick="add()">

<SCRIPT LANGUAGE="javascript">
function Test(objTable) {

   objTR = objTable.insertRow();
   objTR.insertCell();
   objTR.cells[0].innerText = "very happy...";
   objTR.attachEvent("onMouseOver", fover);
   objTR.attachEvent("onMouseOut", fout);
}function fover()
{
   event.srcElement.color = "red";
}function fout()
{
   event.srcElement.color = "blue";
}</SCRIPT><BODY onLoad="Test(table1)">
<table id="table1" border="1"></table>
</BODY>
</HTML>这段代码怎么把鼠标移进移出都没有反映啊？？
lienzhu(李强) 兄的代码确实可以，但是我想知道为什么我上面的这段代码就不可以了呢？？我把onMouseOver替换成 onmouseover，把onMouseOut替换成onmouseout也没有可以再次求助
是因为你的事件函数写错了,你试验一下这个
你修改事件函数就可以了<HTML>
<HEAD><TITLE>Dynamic Styles</TITLE>
<SCRIPT LANGUAGE="javascript">
function Test(objTable) {

   objTR = objTable.insertRow();
   objTR.insertCell();
   objTR.cells[0].innerText = "very happy...";
   objTR.onmouseover = fover;
   objTR.onmouseout = fout;
}function fover()
{
   alert("red");
}function fout()
{
   alert("blue");
}</SCRIPT><BODY onLoad="Test(table1)">
<table id="table1" border="1"></table>
</BODY>
</HTML>
不好意思，开始写错了
try：
<table id="objTable" name="objTable"  width=895 border=1>
</table>
<input type=button onclick="Test()">
<SCRIPT LANGUAGE="javascript">
function Test() {

   objTR = objTable.insertRow();
   objTR.insertCell();
   objTR.cells[0].innerText = "very happy...";
   objTR.attachEvent("onmouseover", fover);
   objTR.attachEvent("onmouseout", fout);
}function fover()
{
   event.srcElement.parentElement.bgColor = "red";
}function fout()
{
   event.srcElement.parentElement.bgColor = "blue";
}</SCRIPT>
或者：
   objTR.setAttribute("onmouseover", fover);
   objTR.setAttribute("onmouseout", fout);
