Question

javascript 修改form表单的值

<form action="mystruts/sum.action">
<input id="name" type="hidden" name="user.name" value="tom">
<input type="text" name="user.operand1"><br />
<input type="text" name="user.operand2">
<input type="submit" value="提交" onclick="javascript:toPage('Jim')">
</form>

<script type="text/javascript">
function toPage(name) {
var form=document.forms[0];
//
alert(ss);
form.submit();
}
</script>
提交表单时，在toPage方法里怎样修改 <input id="name" type="hidden" name="user.name" value="tom">的值？

document.getElementById("name").value = name;
form.submit();
}
</script>
