    document.body.removeChild(document.getElementById("alertbgDiv"));
    document.getElementById("alertmsgDiv").removeChild(document.getElementById("alertmsgTitle"));
    document.body.removeChild(document.getElementById("alertmsgDiv"));
}

使用方法は直接Alert('ヒント情報')を呼び出すと、次のようになります.

     function form_check(){
     if(document.form1.user.value==""){Alert("请输入用户名！");document.form1.user.focus();return (false);}
     if(document.form1.password.value==""){Alert("请输入密码！");document.form1.password.focus();return (false);}
     }
</script>

<form name="form1" onsubmit="return form_check();" method="post" action="login.asp"> 
用户名： <input name="user" type="text" id="user"/>
密码： <input name="password" type="password" id="password" />
<INPUT id=btnEnter type=image src="images/login.gif" name=btnEnter>
