Vue 常用工具类

1.验证手机号

//验证手机号
function isPoneAvailable(str) {
  var myreg = /^[1][3,4,5,6,7,8,9][0-9]{9}$/;
  if (!myreg.test(str)) {
    return false;
  } else {
    return true;
  }
}

2.格式化日期

function formatZNdate(date) {
  var year = date.getFullYear();
  var month = date.getMonth() + 1;
  var day = date.getDate();
  if (month < 10) {
      month = "0" + month;
  }
  if (day < 10) {
      day = "0" + day;
  }
  var nowDate = `${year}年${month}月${day}日`
  return nowDate
}

3.身份证判断年龄

/**
 * 判断年龄
 * @param {*} UUserCard 
 * @returns 
 */
function getIdCard(UUserCard) {
  //获取年龄
  var myDate = new Date();
  var month = myDate.getMonth() + 1;
  var day = myDate.getDate();
  var age = myDate.getFullYear() - UUserCard.substring(6, 10) - 1;
  if (UUserCard.substring(10, 12) < month || UUserCard.substring(10, 12) == month && UUserCard.substring(12, 14) <= day) {
      age++;
  }
 return age
}

4.身份证获取性别

// 身份证获得性别
function getSex(idCard) {
    var sexStr = '';
    if (parseInt(idCard.slice(-2, -1)) % 2 == 1) {
        sexStr = '男';
    }
    else {
        sexStr = '女';
    }
    return sexStr;
}

5.判断身份证格式

function isIdCard(idCard){
                let reg = /^[1-9]\d{5}(18|19|20|(3\d))\d{2}((0[1-9])|(1[0-2]))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/;
                if (reg.test(idCard)) {
                    return true
                } else{
                    return false
                }
            }

6.获得生日格式

            function getBirthday(idCard){              
                var birthday = "";
                if(idCard != null && idCard != ""){
                    if(idCard.length == 15){
                        birthday = "19"+idCard.substr(6,6);
                    } else if(idCard.length == 18){
                        birthday = idCard.substr(6,8);
                    }
                
                    birthday = birthday.replace(/(.{4})(.{2})/,"$1-$2-");
                }
                
                return birthday;                      
            }

7. 判断当前时间到时到了某个截止时间

            function getBirthday(endTime){
                // 将 2022-01-01 包含“-”符号的替换成“/”（兼容iOS时间戳转换成null的bug）
                var dateTime = endTime.replace(/-/g, "/");
                
                var endtimes=(new Date(this.dateTime)).getTime()
                var nowtimes=(new Date()).getTime()
                if (endtimes>nowtimes) {//如果结束时间大于当前时间 没有到期
                  return true
                } else {
                 return false
                }                      
            }

 8.时间戳转换为日小时分秒

//通过时间戳的方式来 
//var day =  parseInt（总秒数/60/60/24）;//天
// var  t  =  parseInt（总秒数/60/60%24）;//时
// var  m  =  parseInt（总秒数/60%60）;//分
// var  s  =  parseInt（总秒数%60）;//秒
function countDown(inputTime) {

var days = parseInt (mss / (1000 * 60 * 60 * 24));
var hours = parseInt((mss % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = parseInt((mss % (1000 * 60 * 60)) / (1000 * 60));
var seconds = (mss % (1000 * 60)) / 1000;
return days + " 天 " + hours + " 小时 " + minutes + " 分钟 ";

}

 9.获取当前时间的周一至周日时间（一周所在的日期）

function getWeekDay(presentDate) {                  
  let    today = presentDate.getDay() !== 0 ? presentDate.getDay() : 7;     
  console.log(today)
  return Array.from(new Array(7), function(val, index) {
    return formatDates(new Date(presentDate.getTime() - (today - index-1) * 24 * 60 * 60 * 1000));
  });                          
  function formatDates(date) {
        return date.getFullYear() + '-' + (date.getMonth() + 1) + '-' + date.getDate()+" 00:00:00";
  }
}
