网页编程多行文本框的非空验证怎么写啊```
以下是我写的.运行不成功.换成TEXT就可以运行
<script>
function noempty(obj)
{
if(obj.txtresume.value=="")
{
alert("姓名不能为空！");
obj.txtresume.focus();
return false;
}
}
</script>
<form action="logado.asp" method=post border=0 onSubmit="return noempty(this);">
<br>
<textarea rows=10 cols=10 name=txtresume></textarea>
<br>
<input type=submit name=cmdOK value="应聘">
</form>
