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="__res__/images/logo.png" alt="layui"> </a> <ul class="layui-nav fly-nav-user"> <!-- 未登入的状态 --> <li class="layui-nav-item"> <a class="iconfont icon-touxiang layui-hide-xs" href="user/login.html" rel="external nofollow" ></a> </li> <li class="layui-nav-item"> <a href="{:u('device/login')}" rel="external nofollow" rel="external nofollow" >登入</a> </li> <li class="layui-nav-item"> <a href="javascript::void;" rel="external nofollow" >注册</a> </li> </ul> </div> </div> <div class="layui-container fly-margintop"> <div class="fly-panel fly-panel-user" pad20> <div class="layui-tab layui-tab-brief" lay-filter="user"> <ul class="layui-tab-title"> <li><a href="{:u('device/login')}" rel="external nofollow" rel="external nofollow" >登入</a></li> <li class="layui-this">注册</li> </ul> <div class="layui-form layui-tab-content" id="lay_ucm" style="padding: 20px 0;"> <div class="layui-tab-item layui-show"> <div class="layui-form layui-form-pane"> <form method="post"> <div class="layui-form-item"> <label for="l_username" class="layui-form-label">手机</label> <div class="layui-input-inline"> <input type="text" id="signuppassdata" name="phone" required lay-verify="required" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <label for="l_username" class="layui-form-label">卡号</label> <div class="layui-input-inline"> <input type="text" id="cardno" name="cardno" required lay-verify="required" autocomplete="off" class="layui-input"> </div> </div> <div class="layui-form-item"> <button class="layui-btn" type="submit" lay-filter="reg" lay-submit="" id="signuppass" >立即注册</button> </div> </form> </div> </div> </div> </div> </div> </div> <div class="fly-footer"> <p>开门社区 2018 © <a href="http://www.100txy.com/" rel="external nofollow" target="_blank">100txy.com 出品</a></p> <p><a href="javascript::void;" rel="external nofollow" target="_blank">雷小天博客</a></p> </div> <script src="__public__/mobile/js/jquery.js"></script> <script src="__res__/layui/layui.js"></script> <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。
