Verify the ID number and email address and determine what the selected regular pattern of checked looks like.

This time I will bring you the regular rules for verifying the ID number and email address and judging the checked selection. The regular rules for verifying the ID number and email address and judging the checked selection Notes What are they? Here are actual cases. Let’s take a look.

The project happened to write about login and registration. When using the blur event to verify the user input, a bug appeared. Finally, the user input value was obtained in the onclick event of the registration button for verification.

Judge the checked status:

if(!$('#checkedAgree').prop("checked"){ 
   console.log('no');//未选中 
}else{ 
   console.log('yes');//选中 
} 
//注册 
$(".regBtn").on('click',function(){ 
  var regUser = $('#regUser').val();//用户名 
  var regPass = $('#regPass').val();//密码 
  var regAgainpass = $('#regAgainpass').val();//确认密码 
  var regTrueName = $('#regTrueName').val();//真实姓名 
  var idNumber = $('#idNumber').val();//身份证 
  var email = $('#email').val();//邮箱 
  if(!regUser){ 
    alert("用户名为空，请输入用户名"); 
  }else if(!regPass || regPass.length < 6){ 
    alert("密码为空或长度少于6位，请输入正确的密码"); 
  }else if(!regAgainpass || regAgainpass != regPass){ 
    alert("确认密码为空或两次密码输入不一致，请输入正确的密码"); 
  }else if(!regTrueName){ 
    alert("真实姓名为空，请输入真实姓名"); 
  }else if(!idNumber || !idNum(idNumber)){//调用身份证验证方法 
    alert("身份证号码不正确，请输入正确的身份证号码"); 
  }else if(!email || !emailNum(email)){//调用邮箱验证方法 
    alert("邮箱不正确，请输入正确的邮箱email"); 
  }else if(!$('#checkedAgree').prop("checked")){//判断用户同意注册协议状态 
    alert("您还未同意用户注册协议"); 
  }else{ 
    console.log('yes'); 
    //some code here 
  } 
}); 
//身份号码验证 
function idNum(idNum){ 
  var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; 
  if(!reg.test(idNum)){ 
    return false; 
  }else{ 
    return true; 
  } 
} 
//邮箱验证 
function emailNum(emailNum){ 
  var reg = /^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+((\.[a-zA-Z0-9_-]{2,3}){1,2})$/;//验证身份证号 
  if(!reg.test(emailNum)){ 
    return false; 
  }else{ 
    return true; 
  } 
}
