在layui中使用form表單監(jiān)聽ajax異步驗(yàn)證注冊的實(shí)例

今天小編就為大家分享一篇在layui中使用form表單監(jiān)聽ajax異步驗(yàn)證注冊的實(shí)例，具有很好的參考價(jià)值，希望對大家有所幫助。一起跟隨小編過來看看吧

今天給大家介紹的是當(dāng)下很流行的框架layui中的一個(gè)小案例、就是form表單監(jiān)控提交并且使用ajax異步提交驗(yàn)證數(shù)據(jù)。在layui中我們想使用哪個(gè)模塊就要layui.use('form',function{});這種形式要引用form內(nèi)置模板，下面是HTML全部代碼

//監(jiān)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(jī)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(jī)號碼', {icon: 2});
  return false;
 }
 if(cardno.length!=8){
  layer.msg('請輸入有效的卡片內(nèi)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(zhuǎn)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(yè)務(wù)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(nèi)碼，請聯(lián)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(jìn)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(qū)
  $new_area=$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(qū)的租戶，請勿重復(fù)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！'));
  }
  }

 }
 }

以上這篇在layui中使用form表單監(jiān)聽ajax異步驗(yàn)證注冊的實(shí)例就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
