人生不可能总是顺心如意的,但是持续朝着阳光走,影子就会躲在后面。刺眼,却表明对的方向。
本文实例讲述了jQuery实现倒计时重新发送短信验证码功能的方法。分享给大家供大家参考,具体如下:
<!DOCTYPE html> <html> <head> <script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js"></script> <script type="text/javascript"> var countdown=60; function settime(obj) { if (countdown == 0) { obj.removeAttribute("disabled"); obj.value="免费获取验证码"; countdown = 60; return; } else { obj.setAttribute("disabled", true); obj.value="重新发送(" + countdown + ")"; countdown--; } setTimeout(function() { settime(obj) } ,1000) } </script> <body> <input type="button" id="btn" value="免费获取验证码" onclick="settime(this)" /> </body> </html>
实践例子:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>抢占iPhone7专属预订名额</title> <link rel="stylesheet" rel="nofollow noopener noreferrer" href="getiphone.css" /> </head> <body style="width: 100%;height: 100%;background:#fff url(iponeImg/beijing.png) no-repeat center fixed;background-size:100% 100%;text-align: center;"> <div class="top"> <img src="iponeImg/wenan.png" /> </div> <h1 class="title"><span></span>上市时间同步发售<span></span><br />首批新苹果30个预订专属名额</h1> <form id="activityForm" class="form-horizontal" method="post" action="/wamei/activityController/save.htm"> <label> <span><img src="iponeImg/yonghu.png" /></span> <i></i> <input type="text" class="inline-input" id="name" name="name" placeholder="请输入您的真实姓名" datatype="*1-20" errormsg="姓名最多20个中英文字符!" nullmsg="请输入您的真实姓名!" /> </label> <label> <span><img src="iponeImg/dianhua.png" /></span> <i></i> <input type="text" class="inline-input" id="mobilePhone" name="mobilePhone" placeholder="请输入您的手机号码" datatype="*" errormsg="请输入您的手机号码!" nullmsg="请输入您的手机号码!" /> </label> <label> <span><img src="iponeImg/yanzhengma.png" /></span> <i></i> <input type="text" id="validateCode" class="inline-input" name="validateCode" placeholder="验证码" datatype="*" errormsg="请输入验证码!" nullmsg="请输入验证码!" style="width:180px;" /> <a id="num" mark="1" >获取验证码</a> </label> <label id="get"> <input id="confirm" type="submit" value="提交抢占名额" /> </label> <label> <a rel="nofollow noopener noreferrer" href="/wamei/pages/activity/details.html" id="activity">查看活动详情</a> </label> </form> <div class="bottom"> <span></span> <img src="iponeImg/logo.png" /> <span></span> </div> <div id="success"> <div class="successImg"> <a class="close"></a> <p><img src="iponeImg/chenggong.png" />恭喜提交成功</p> <p style="padding-top: 0px;font-size: 23px;">分享一下,安抚激动的心</p> </div> </div> </body> </html> <!-- scripts --> <script src="/wamei/pages/js/jquery.min.js"></script> <script src="/wamei/pages/js/jquery.form.js"></script> <script src="/wamei/pages/js/bootstrap.min.js"></script> <script src="/wamei/pages/js/Validform_v5.3.2.js"></script> <script type="text/javascript"> $(function(){ //提交表单 $("#activityForm").Validform({ btnSubmit:"#confirm", tiptype:function(msg){ if(msg != '' && msg!='通过信息验证!'){ alert(msg); } }, tipSweep:true, beforeSubmit:function(){ saveForm(); return false; } }); }); //只允许在APP内打开 function isMobile(){ var u = navigator.userAgent; var mobileFlag = u.indexOf('type/tfbrowser') > -1; return mobileFlag; } //手机号码验证 $("#mobilePhone").blur(function(){ var mobilePhone =$("#mobilePhone").val(); var myreg = /^(((13[0-9]{1})|(14[0-9]{1})|(17[0]{1})|(15[0-3]{1})|(15[5-9]{1})|(18[0-9]{1}))+\d{8})$/; if(mobilePhone){ if(!myreg.test(mobilePhone)){ alert("请输入有效的手机号码!"); $("#mobilePhone").val(""); return ; } } }); //发送短信验证码 $("#num").click(function(){ var mobilePhone =$("#mobilePhone").val(); var url="/wamei/activityController/sendValidCode.htm"; if(!mobilePhone){ alert("请输入您的手机号码!"); return ; } var mark = $("#num").attr("mark"); if("1"==mark){ settime(this); $.post(url,{mobilePhone:mobilePhone},function(html){ var data = eval("("+html+")"); if(data && data.statusCode==1){ console.log("send success!"); alert("短信验证码已发送,请查收!"); }else{ alert(data.msg); } }); } }); //提交form表单 function saveForm(){ $("#activityForm").ajaxSubmit({ //data: {'columnStr':columnStr}, type: 'post', async: false, success: function($data) { var data = eval("("+$data+")"); if(data && data.statusCode==1){ $("#success").show(); }else{ alert(data.msg); $("#mobilePhone").val(""); } } }); } $(".close").click(function(){ $("#success").hide(); window.location.reload(); }) //短信后倒计时 var countdown=60; function settime(obj) { if (countdown == 0) { $(obj).attr("disabled",false); $(obj).attr("mark","1"); $(obj).html("获取验证码"); countdown = 60; return; } else { $(obj).attr("disabled", true); $(obj).attr("mark","0"); $(obj).html("重新发送(" + countdown + ")"); countdown--; } setTimeout(function() { settime(obj) } ,1000) } // $("#confirm").click(function(){ // $("#success").show(); // }) </script>
