JS实现表单验证功能(验证手机号是否存在,验证码倒计时)
废话不多说直接上代码
html代码:
<form method="post" id="form_hroizon" enctype="multipart/form-data" action="/"> <input type="hidden" name="phoneTemplet" id="phoneTemplet"> <input type="hidden" name="regType" id="regType"> <div class="c-login-input"> <div class="form-group"> <label for="inputEmail3" class="label-control label-width120 pull-left t-r-f f16">手机号</label> <div class="pull-left"> <input type="tel" autocomplete="off" class="input-control put-width440 j-telphone" id="inputtel" name="phones" placeholder="请输入您的电话号码" value=""> <span class="f12 red tel-msg"></span> <div class="c-login-errtips" style="display:none;"></div> </div> </div> <div class="form-group"> <label for="inputEmail3" class="label-control label-width120 pull-left t-r-f f16">登录密码</label> <div class="pull-left"> <input type="password" class="input-control put-width440 fistpwd" id="inputpwd" name="password" placeholder="请输入密码" value=""> <span class="f12 red pwd-msg"></span> </div> </div> <div class="form-group"> <label for="inputEmail3" class="label-control label-width120 pull-left t-r-f f16">验证码</label> <div class="pull-left"> <input type="tel" class="input-control put-with100 vericode" id="inputEmail3" name="code" placeholder="请输入验证码"> <input id="btnSendCode" type="button" value="免费获取验证码" class="j-getcode f12 b-i-k btn code-btn c-p" /> <span class="f12 red code-msg"></span> </div> </div> </div> <div class="form-group"> <a class="j-sends" type="submit" name="submit" target="_self" href="javascript:void(0)">注册</a> </div> </form>
JS代码:
<script type="text/javascript"> $(function(){ $(".j-sends").click(function(){ var phones = $.trim($(".j-telphone").val()); var isMobile=/^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/; if(!phones){ $('.tel-msg').text('请输入手机号码,不能为空'); return false; }else if (!isMobile.test(phones)) { $('.tel-msg').text('请输入有效的手机号码'); return false; }else{ //手机号码是否存在 $.ajax({ url : "/", // type:"post", dataType:"JSON", data:{ phones: phones, }, contentType:'application/json;charset=UTF-8', //async: false, success:function(data){ if (data.flag == "1") { // $('.tel-msg').html(data.errorInfo); // return false; }else{ $('.tel-msg').html(data.errorInfo); //可 } }, error:function(){ } }); } }) //验证码倒计时 var InterValObj; //timer变量,控制时间 var count = 30; //间隔函数,1秒执行 var curCount;//当前剩余秒数 var code = ""; //验证码 var regType; var phoneTemplet; var codeLength = 4;//验证码长度 $(".code-btn").click(function(){ curCount = count; var phone=$.trim($(".j-telphone").val());//手机号码 var isMobile=/^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/; var jtel = $(".j-telphone"); if(phone != "" && isMobile.test(phone) && phone.length==11){ //设置button效果,开始计时 $("#btnSendCode").attr("disabled", "true"); $("#btnSendCode").val("请在" + curCount + "秒内输入验证码"); InterValObj = window.setInterval(SetRemainTime, 1000); //启动计时器,1秒执行一次 //产生验证码 for (var i = 0; i < codeLength; i++) { code += parseInt(Math.random() * 9).toString(); } //向后台获验证码 $.ajax({ url : base + "/", type: "POST", // dataType: "text", // data: "phones=" + phone + "&code=" + code, dataType: "JSON", data:{ phones:phone, code: code, regType:"1", phoneTemplet:"phone_uc" }, success: function (data){ if(data.flag=="F"){ $(".code-msg").html(data.errorInfo); }else{ $(".code-msg").html(data.errorInfo); } } }); }else{ $('.tel-msg').text('请输入有效的手机号码'); } }); //timer处理函数 function SetRemainTime() { if (curCount == 0) { window.clearInterval(InterValObj);//停止计时器 $("#btnSendCode").removeAttr("disabled");//启用按钮 $("#btnSendCode").val("重新发送验证码"); code = ""; //清除验证码。如果不清除,过时间后,输入收到的验证码依然有效 } else { curCount--; $("#btnSendCode").val("请在" + curCount + "秒内输入验证码"); } } }) </script>
