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"> <meta name="keywords" content="雷小天"> <meta name="description" content="雷小天博客-layui中使用form表单监听异步验证注册"> <link rel="stylesheet" href="__RES__/layui/css/layui.css" rel="external nofollow" > <link rel="stylesheet" href="__RES__/css/global.css" rel="external nofollow" > </head> <body> <div class="fly-header layui-bg-black"> <div class="layui-container"> <a class="fly-logo" href="{:U('device/getinfo')}" rel="external nofollow" > <img src="/UploadFiles/2021-04-02/logo.png">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。
