jquery regular expression verification (mobile phone number, ID number, Chinese name)_jquery

The content that needs to be verified in the example of this article: Chinese name, mobile phone number, ID card and address. The verification method is shared with everyone for your reference. The specific content is as follows

HTML (form):

<form action="">
 <div class="form-group">
  <label>姓名：</label>
  <input id="name" type="text">
 </div>
 <div class="form-group">
  <label>手机号：</label>
  <input id="phone" type="text">
 </div>
 <div class="form-group">
  <label>身份证：</label>
  <input id="identity" type="text">
 </div>
 <div class="form-group">
  <label class="label-textarea">邮寄地址：</label>
  <textarea id="address"></textarea>
 </div>
 <p class="tip">请填写实名认证信息，以便领奖资料一经提交无法修改，请慎重填写！</p>
 <div class="btn-group">
  <button class="btn btn-md btn-purple" type="reset">取消</button>
  <button class="btn btn-md btn-purple ml-20" id="submit" type="button">提交</button>
 </div>
</form>

jQuery validation:

The test() method determines whether the regular expression content is matched in the string, and returns a boolean value (true / false)

// 验证中文名称
function isChinaName(name) {
 var pattern = /^[\u4E00-\u9FA5]{1,6}$/;
 return pattern.test(name);
}

// 验证手机号
function isPhoneNo(phone) { 
 var pattern = /^1[34578]\d{9}$/; 
 return pattern.test(phone); 
}

// 验证身份证 
function isCardNo(card) { 
 var pattern = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; 
 return pattern.test(card); 
} 

// 验证函数
function formValidate() {
 var str = '';

 // 判断名称
 if($.trim($('#name').val()).length == 0) {
  str += '名称没有输入\n';
  $('#name').focus();
 } else {
  if(isChinaName($.trim($('#name').val())) == false) {
   str += '名称不合法
';
   $('#name').focus();
  }
 }

 // 判断手机号码
 if ($.trim($('#phone').val()).length == 0) { 
  str += '手机号没有输入
';
  $('#phone').focus();
 } else {
  if(isPhoneNo($.trim($('#phone').val()) == false)) {
   str += '手机号码不正确
';
   $('#phone').focus();
  }
 }

 // 验证身份证
 if($.trim($('#identity').val()).length == 0) { 
  str += '身份证号码没有输入
';
  $('#identity').focus();
 } else {
  if(isCardNo($.trim($('#identity').val())) == false) {
   str += '身份证号不正确；\n';
   $('#identity').focus();
  }
 }

 // 验证地址
 if($.trim($('#address').val()).length == 0) { 
  str += '地址没有输入\n';
  $('#address').focus();
 }

 // 如果没有错误则提交
 if(str != '') {
  alert(str);
  return false;
 } else {
  $('.auth-form').submit();
 }
}

$('#submit').on('click', function() {
 formValidate();
});
