前端vue中清除Cookie方法

1.清除所有cookies

 delCookie() {
      var cookies = document.cookie.split(";");
      for (var i = 0; i < cookies.length; i++) {
        var cookie = cookies[i];
        var eqPos = cookie.indexOf("=");
        var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
        document.cookie =
          name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/";
      }
      if (cookies.length > 0) {
        for (var i = 0; i < cookies.length; i++) {
          var cookie = cookies[i];
          var eqPos = cookie.indexOf("=");
          var name = eqPos > -1 ? cookie.substr(0, eqPos) : cookie;
          var domain = location.host.substr(location.host.indexOf("."));
          document.cookie =
            name +
            "=;expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/; domain=" +
            domain;
        }
      }
    }
