前端常用方法

常用方法

// 1、根据身份证获取信息
export function getInfoByID(idNum) {
  const result = {}
  //获取出生日期
  result.birth = idNum.substring(6, 10) + "-" + idNum.substring(10, 12) + "-" + idNum.substring(12, 14);

  //获取性别
  result.sex = parseInt(idNum.substr(16, 1)) % 2 === 1 ? '男' : '女'

  //获取年龄
  const myDate = new Date();
  const month = myDate.getMonth() + 1;
  const day = myDate.getDate();
  let age = myDate.getFullYear() - idNum.substring(6, 10) - 1;
  if (idNum.substring(10, 12) < month || idNum.substring(10, 12) == month && idNum.substring(12, 14) <= day) {
    age++;
  }
  result.age = age;
  return result;
}

// 获取链接参数
 function getUrlQuery() {
      var sHref = window.location.href;
      var args = sHref.split('?');
      if (args[0] === sHref) {
        return {};
      }
      var hrefarr = args[1].split('#')[0].split('&');
      var obj = {};
      for (var i = 0; i < hrefarr.length; i++) {
        hrefarr[i] = hrefarr[i].split('=');
        obj[hrefarr[i][0]] = hrefarr[i][1];
      }
      return obj;
    }
