今天給大家介紹的是當下很流行的框架layui中的一個小案例、就是form表單監控提交并且使用ajax異步提交驗證數據。在layui中我們想使用哪個模塊就要layui.use('form',function{});這種形式要引用form內置模板，下面是HTML全部代碼
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>注冊</title>

//監聽提交
layui.use('form', function(){
var form = layui.form;
form.on('submit(reg)', function(data){
// layer.msg(JSON.stringify(data.field));//彈出json格式所有表單的值
var phone=data.field.phone;
var cardno=data.field.cardno;
if(phone.length!=11){
layer.msg('請輸入有效的手機號碼', {icon: 2});
return false;
}
var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/;
if(!myreg.test(phone)){
layer.msg('請輸入有效的手機號碼', {icon: 2});
return false;
}
if(cardno.length!=8){
layer.msg('請輸入有效的卡片內碼！', {icon: 2});
return false;
}
$.ajax({
type:"POST",
url:"index.php?m=Home&c=Device&a=ajax_reg",
data:"phone="+phone+"&cardno="+cardno,
dataType:"json",
success:function(data){
if(data.status=='yes'){
layer.msg('注冊成功！', {icon: 1});
var url = "{:U('device/getinfo')}"; //成功跳轉的url
setTimeout(window.location.href=url,2000);
}else{
layer.msg(data.msg, {icon: 2});
}
},
});
return false;
});
});
</script>
</body>
</html>
下面是ajax_reg邏輯方面，這是我的業務邏輯大家沒必要照搬，知道怎么用就行了
//表單異步提交
public function ajax_reg(){
if(isset($_POST['phone'])&&isset($_POST['cardno'])){
$roomnostr = M("userinfo")->where(array('cardno'=>$_POST['cardno']))->getField('roomno');
if(!$roomnostr){
echo json_encode(array('status'=>'no','msg'=>'無效的卡片內碼，請聯系管理員！'));
exit();
}
$wechatinfo=$_SESSION['wechatinfo'];
if(!$wechatinfo){
echo json_encode(array('status'=>'no','msg'=>'頁面已過期請重新掃碼進入！'));
exit();
}
$result= M("weixin")->where(array('openid'=>$wechatinfo['openid']))->field('is_signup,area_id')->find();
$areaArr=explode('-',$result['area_id']);
// $result=M("weixin")->getFieldByOpenid($_POST['openid'],'is_signup');
if(isset($result)&&$result['is_signup']==1){//如果注冊過一次下次只更新門區
$new_area=$roomnostr;
$reg=M("weixin")->where(array('openid'=>$wechatinfo['openid']))->save(array('area_id'=>$new_area));
echo json_encode(array('status'=>'no','type'=>'signuppass','msg'=>'你已注冊為該門區的租戶，請勿重復注冊！'));
exit();
}else{
$data=array(
'is_signup'=>1,
'phone'=>$_POST['phone'],
'openid'=>$wechatinfo['openid'],
'nickname'=>$wechatinfo['nickname'],
'sex'=>$wechatinfo['sex'],
'headimgurl'=>$wechatinfo['headimgurl'],
'area_id'=>$roomnostr,
'regtime'=>time(),
'cardno'=>$_POST['cardno'],
);
$reg=M("weixin")->add($data);
if($reg){
echo json_encode(array('status'=>'yes','msg'=>'恭喜你，注冊成功！'));
}
}
}
}
