JS代码随机生成手机号、身份证号、银行卡号、不重复订单号-Vue

本章记录vue开发过程中随机生成手机号、身份证号、银行卡号、不重复订单号四种方法函数

1.随机生成手机号：

getMoble(callback) {
      var prefixArray = new Array("130", "131", "132", "133", "135", "137", "138", "170", "187", "189");
      var i = parseInt(10 * Math.random());
      var prefix = prefixArray[i];
      for (var j = 0; j < 8; j++) {
        prefix = prefix + Math.floor(Math.random() * 10);
      }
      callback(prefix)
    }
//调用方法为：
this.getMoble(res=> {
       console.log('手机号：',res)
  })

2.随机生成身份证号：

getId_no(callback){
      var coefficientArray = [ "7","9","10","5","8","4","2","1","6","3","7","9","10","5","8","4","2"];// 加权因子
      var lastNumberArray = [ "1","0","X","9","8","7","6","5","4","3","2"];// 校验码
      var address = "420101"; // 住址
      var birthday = "19810101"; // 生日
      var s = Math.floor(Math.random()*10).toString() + Math.floor(Math.random()*10).toString() + Math.floor(Math.random()*10).toString();
      var array = (address + birthday + s).split("");
      var total = 0;
      for (const i of array) {
        total = total + parseInt(array[i])*parseInt(coefficientArray[i]);
      }

      var lastNumber = lastNumberArray[parseInt(total%11)];
      var id_no_String = address + birthday + s + lastNumber;
      callback(id_no_String)
    }
//调用方法为：
this.getId_no(res=> {
       console.log('身份证号：',res)
  })

3.随机生成银行卡号：

getBank_account(callback) {
      var arrStr = ['0102', '0103', '0105', '0301', '104', '0303', '305', '0306', '0308', '0410', '302', '304', '309', '310', '315', '316']
      var bank_no = arrStr[Math.floor(Math.random() * arrStr.length)]
      var prefix = ''
      switch (bank_no) {
        case '0102':
          prefix = '622202'
          break
        case '0103':
          prefix = '622848'
          break
        case '0105':
          prefix = '622700'
          break
        case '0301':
          prefix = '622262'
          break
        case '104':
          prefix = '621661'
          break
        case '0303':
          prefix = '622666'
          break
        case '305':
          prefix = '622622'
          break
        case '0306':
          prefix = '622556'
          break
        case '0308':
          prefix = '622588'
          break
        case '0410':
          prefix = '622155'
          break
        case '302':
          prefix = '622689'
          break
        case '304':
          prefix = '622630'
          break
        case '309':
          prefix = '622908'
          break
        case '310':
          prefix = '621717'
          break
        case '315':
          prefix = '622323'
          break
        case '316':
          prefix = '622309'
          break
        default:
      }

      for (var j = 0; j < 12; j++) {
        prefix = prefix + Math.floor(Math.random() * 10)
      }
      callback(prefix)
    }
//调用方法为：
this.getBank_account(res=> {
       console.log('银行卡号：',res)
  })

4.随机生成不重复订单号：

/**
     * 随机生成18位不重复的订单编号
     * length 随机后缀字符长度，默认为4
     */
    generateOrderNumber(length = 4,callback) {
      const now = new Date()
      let year = now.getFullYear().toString()
      let month = (now.getMonth() + 1)
      let day = now.getDate()
      let hour = now.getHours()
      let minutes = now.getMinutes()
      let seconds = now.getSeconds()
      // 个位数补齐十位数
      month = month < 10 ? '0' + month : month
      day = day < 10 ? '0' + day : day
      hour = hour < 10 ? '0' + hour : hour
      minutes = minutes < 10 ? '0' + minutes : minutes
      seconds = seconds < 10 ? '0' + seconds : seconds

      month = month.toString()
      day = day.toString()
      hour = hour.toString()
      minutes = minutes.toString()
      seconds = seconds.toString()

      // 存放订单号
      let num = ''
      // N位随机数(加在时间戳后面)
      for (var i = 0; i < length; i++) {
        num += Math.floor(Math.random() * 10)
      }
      callback('Sj' + year + month + day + hour + minutes + seconds + num)
    }
//调用方法为：
this.generateOrderNumber(4,res =>{
        console.log('订单号：',res)
      })
