单击表格中某个单元格则这个单元格变颜色
<script language="JavaScript">
function test(t) {
for (var i=0; i<t.rows.length; i++)
for (var j=0; j<t.rows[i].cells.length; j++)
t.rows[i].cells[j].bgColor = t.rows[i].cells[j] == event.srcElement ? 'red' : '';
}
</script>
<table width="300" cellspacing="1" bgcolor="black" onClick="test(this)">
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>

单选框问题
有三个单选框，
<input type=radio name=1>222
<input type=radio name=2>222
<input type=radio name=3>222
怎么样使选中第一个后才能选择下面两个中的一个。
<script>
function change(radobj){
var obj = document.getElementsByName("radio2");
for(i=0;i<obj.length;i++){
obj[i].disabled = !radobj.checked;
}
}
</script>
<input type=radio name="radio1" onclick=change(this)>222
<input type=radio name="radio2" disabled>222
<input type=radio name="radio2" disabled>222
鼠标划过，表格变色
<table cellpadding="0" cellspacing="0" width="100%">
<tr onmouseover="this.bgColor='red'" onmouseout="this.bgColor=''">
<td>This is only an Example</td><td>This is only an Example</td>
