帮忙看看 onMouseOver 怎么加?
<html>
<head>
<title> 校内新闻 </title>
</head>
<body>
<table border=0 width=190>
<tr> <td colspan=2 height=10> </tr>
<tr>
<td width=8 align=center> </td>
<td width=182 align=left> 校内新闻1 </td>
</tr>
<tr>
<td width=8 align=center> > </td>
<td width=182 align=left> 校内新闻2 </td>
</tr>
<tr>
<td width=8 align=center> </td>
<td width=182 align=left> 校内新闻3 </td>
</tr>
<tr> <td colspan=2 height=10> </tr>
</table>
</body>
</html>
========================
当前结果是:
校内新闻1
> 校内新闻2
校内新闻3
========== 我想动态的实现鼠标移到新闻1上时> 出现2和3上的> 消失,移到2上时> 出现1和3上> 消失,移到3上时> 出现1和2消失============
我该怎么写?
------解决方案-------------------- <html>
<head>
<title> 校内新闻 </title>
</head>
<body onLoad= "init(); ">
<script>
function init(){
var table = document.getElementById( "table1 ");
var spans = table.getElementsByTagName( "span ");
for(var i = 0 ; i < spans.length ;i++){
spans[i].onmouseover = function(){
this.innerHTML = "> " + this.innerHTML;
}
spans[i].onmouseout = function(){
if(this.innerHTML.indexOf( "> ") != -1) this.innerHTML = this.innerHTML.substring(1);
}
}
}
</script>
<table border=0 width=190 id= "table1 ">
<tr> <td colspan=2 height=10> </tr>
<tr>
<td width=8 align=right> </td>
<td width=182 align=right> <span id= "test "> 校内新闻1 </span> </td>
</tr>
<tr>
<td width=8 align=right> </td>
<td width=182 align=right> <span id= "test "> 校内新闻2 </span> </td>
</tr>
<tr>
<td width=8 align=right> </td>
<td width=182 align=right> <span id= "test "> 校内新闻3 </span> </td>
</tr>
<tr> <td colspan=2 height=10> </tr>
</table>

------解决方案--------------------onmouseover,onmouseout都要写
类似以下:
<script>
function show1(i,v)
{
document.getElementById(i).innerHTML = '> '+v;
}
function show2(i,v)
{
var x = v;
document.getElementById(i).innerHTML = x.replace(/^>(.*)/, '$1 ');
}
</script>
<table border=0 width=190>
<tr> <td colspan=2 height=10> </tr>
<tr>
<td width=182 align=left id= "new1 " onmouseover= "show1(this.id,this.innerHTML) " onmouseout= "show2(this.id,this.innerHTML) "> 校内新闻1 </td>
</tr>
<tr>
<td width=182 align=left id= "new2 " onmouseover= "show1(this.id,this.in
