cookie的使用

//获取cookie
export function getCookie(name) {
  var reg = RegExp(name + '=([^;]+)');
  var arr = document.cookie.match(reg);
  if (arr) {
    return arr[1];
  } else {
    return '';
  }
}

//设置cookie,增加到vue实例方便全局调用
export function setCookie(name, value, day) {
  var date = new Date();
  date.setDate(date.getDate() + day);
  document.cookie = name + '=' + value + ';expires=' + date;
};

//删除cookie
export function delCookie(name) {
  setCookie(name, null, -1);
};
