<form action="/plus/diy.php" enctype="multipart/form-data" method="post">
改成
<form action="/plus/diy.php" enctype="multipart/form-data" method="post" onsubmit="javascript:return chkfrm(this);">
加入如下脚本:
<script language="javascript">
function chkfrm(frm){
if(frm.xingming.value==''){
alert('请填写姓名!');
return false;
}
if(frm.lianxidianhua.value==''){
alert('请填写联系电话!');
return false;
}
if(frm.inc.value=='请选择您的范围'){
alert('请选择税后收入!');
return false;
}
if(frm.shenqingleixing.value=='选择申请类型'){
alert('请选择申请类型!');
return false;
}
if(frm.xiangxineirong.value==''){
alert('请填写详细内容!');
return false;
}
}
</script>
