斑竹,为什么不执行document.form1.sid.focus();这句了,每次点了确定后
<script language="javascript">function checkform()
{
var message="你注册的信息为："
if(document.form1.sid.value=="")
{
alert("输入用户名！");
document.form1.sid.focus();
}
if(document.form1.name.value=="")
{
alert("输入姓名！");
document.form1.name.focus();}
if(document.form1.pass1.value=="")
{
alert("输入密码！");
document.form1.pass1.focus();
}
if(document.form1.pass2.value=="")
{
alert("输入确认密码！");
document.form1.pass2.focus();
}
if (document.form1.pass1.value!=document.form1.pass2.value)
{
alert("重新输入密码！");
document.form1.pass1.focus();
}
var address=document.form1.email.value;
if((address=="")||(address.indexOf([email=]'@')==-1)||(address.indexOf('.')==-1[/email]))
{
alert("邮址不正确！");
document.form1.email.focus();
}
var myindex=form1.area.selectedIndex;
message+="用户名为："+document.form1.sid.value+" ";
message+="姓名为："+document.form1.name.value+" ";
message+="来自："+form1.area.options[myindex].value+" ";
message=message+"email"+address+" ";
alert(message);
}
