这些经常用到的验证所以写成函数好使用一些：

// 身份证号验证

var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"} 
function isCardID(sId){ 
  var iSum=0 ;
  var info="" ;
  if(!/^\d{17}(\d|x)$/i.test(sId)) return "身份证长度或格式错误"; 
  sId=sId.replace(/x$/i,"a"); 
  if(aCity[parseInt(sId.substr(0,2))]==null) return "身份证地区非法"; 
  sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2)); 
  var d=new Date(sBirthday.replace(/-/g,"/")) ;
  if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "身份证上的出生日期非法"; 
  for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11) ;
  if(iSum%11!=1) return "身份证号非法"; 
  //aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女");//此次还可以判断出输入的身份证号的人性别
  return true;
}

function isTelOk(tel){
    let regex = /0?(13|14|15|17|18|19)[0-9]{9}/;
    if(!regex.test(tel)) return "手机号格式错误！";
    return true;
}

function isChines(name){
    let regex = /[\u4e00-\u9fa5]/ ;
    if(!regex.test(name)) return '姓名必须为中文';
    return true;
}

使用的话直接看案例吧：

let isName = isChines(relName); 
let isTel = isTelOk(tel);
let isCard = isCardID(idcard);
if(relName == '' || isName!=true){
    mui.toast(isName);
    return;
}else if(tel=='' || isTel !=true){
    mui.toast(isTel);
    return;
}else if(idcard =='' || isCard!=true){
    mui.toast(isCard);
    return;
}
