innerHTML怎么会出错？
<table width= "100% " cellpadding=0 cellspacing=0 valign= "top ">
<form id= "avote " action= "addvoting.asp " method= "post " name= "addvote2 ">
<tr>
<td> 选项： </td>
<td> <a href= "# " onclick=add()> 添加 </a> </td>
</tr>
</form>
</table>
<script>
function add()
{
var f = document.getElementById( "avote ");
f.innerHTML += " <tr> <td> 123 </td> <td> 456 </td> <td> 789 </td> </tr> ";
}
</script>
帮我看看吧！这个怎么改啊？
[解决办法]
<div id= "add_tr ">
<table width= "100% " cellpadding=0 cellspacing=0 valign= "top ">
<tr>
<td> 选项： </td>
<td> <a href= "# " onclick=add()> 添加 </a> </td>
</tr>
</table>
</div>
<script>
function add()
{
add_tr.innerHTML += " <table width=\ "100%\ " cellpadding=0 cellspacing=0 valign=\ "top\ "> <tr> <td> 123 </td> <td> 456 </td> <td> 789 </td> </tr> </table> ";
}
</script>
