今天给大家介绍的是当下很流行的框架layui中的一个小案例、就是form表单监控提交并且使用ajax异步提交验证数据。在layui中我们想使用哪个模块就要layui.use('form',function{});这种形式要引用form内置模板，下面是HTML全部代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>注册</title>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

<div class="layui-tab layui-tab-brief" lay-filter="user">

<script>
//监听提交
layui.use('form', function(){
var form = layui.form;
form.on('submit(reg)', function(data){
// layer.msg(JSON.stringify(data.field));//弹出json格式所有表单的值
var phone=data.field.phone;
var cardno=data.field.cardno;
if(phone.length!=11){
layer.msg('请输入有效的手机号码', {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('请输入有效的手机号码', {icon: 2});
return false;
}
if(cardno.length!=8){
layer.msg('请输入有效的卡片内码！', {icon: 2});
return false;
}
$.ajax({
type:"POST",
url:"index.php?m=Home&c=Device&a=ajax_reg",
data:"phone="+phone+"&cardno="+cardno,
dataType:"json",
success:function(data){
if(data.status=='yes'){
layer.msg('注册成功！', {icon: 1});
var url = "{:U('device/getinfo')}"; //成功跳转的url
setTimeout(window.location.href=url,2000);
}else{
layer.msg(data.msg, {icon: 2});
}
},
});
return false;
});
});
</script>
</body>
</html>
下面是ajax_reg逻辑方面，这是我的业务逻辑大家没必要照搬，知道怎么用就行了
//表单异步提交
public function ajax_reg(){
if(isset($_POST['phone'])&&isset($_POST['cardno'])){
$roomnostr = M("userinfo")->where(array('cardno'=>$_POST['cardno']))->getField('roomno');
if(!$roomnostr){
echo json_encode(array('status'=>'no','msg'=>'无效的卡片内码，请联系管理员！'));
exit();
}
$wechatinfo=$_SESSION['wechatinfo'];
if(!$wechatinfo){
echo json_encode(array('status'=>'no','msg'=>'页面已过期请重新扫码进入！'));
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){//如果注册过一次下次只更新门区
$new_area=$roomnostr;
$reg=M("weixin")->where(array('openid'=>$wechatinfo['openid']))->save(array('area_id'=>$new_area));
echo json_encode(array('status'=>'no','type'=>'signuppass','msg'=>'你已注册为该门区的租户，请勿重复注册！'));
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，注册成功！'));
}
}
}
}
以上这篇在layui中使用form表单监听ajax异步验证注册的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持呐喊教程。
