【jq】同一個頁面如何返回上一級

一開始是這樣的

然后點擊日期 是這樣的

如何在點擊提交后返回上一級 也就是返回日歷那塊 不是上一頁！

代碼是上個哥用jq寫的
emmm有沒有大佬請教一下

function riqibiaoge(yryu, yu) {

      var hriqi = yryu;
      var riqi = new Date(hriqi);
      var leftriqi = riqi.getDay();
      if (yu == 1 || yu == 3 || yu == 5 || yu == 7 || yu == 8 || yu == 10 || yu == 12) {
        var tianshu = 31;
      }
      else if (yu == 4 || yu == 6 || yu == 9 || yu == 11) {
        var tianshu = 30;
      }
      else if (yu == 2) {
        var tianshu = 28;
      }
      for (var i = 0; i < tianshu; i++) {
        $('.rili_tian').append('<p>' + (i + 1) + '</p>');
      }
      $('.rili_tian').find('p').eq(0).css('margin-left', (leftriqi * 14.28) + '%');
      timeclick();
     

    }

    //添加月份
    for (var i = 0; i < 12; i++) {
      $('#yuefen').append('<option value ="' + (i + 1) + '">' + (i + 1) + '</option>')
    }
    //添加默認年份
    hahah();
    function hahah() {

      var woca = nia + ',' + (yua + 1) + ',' + 1
      riqibiaoge(woca, yua + 1);
    }

      riqibiaoge(yryu, yu)

    //月份點擊事件
    function timeclick() {

        var tian = $(this).html();  

        for (var i = 1; i < pack.length + 2; i++) {
          $('.kr_top').append('<div>' + timshuzu[i * 2 - 2] + '-' + timshuzu[i * 2 - 1] + '</div>');
          $('.kr_bottom').append('<div class="kr_bd"><select></select></div>')
          $('.kr_bottom').find('div').css('width', 98 / this.value + '%')
          $('.kr_top').find('div').css('width', 98 / this.value + '%')
        }
        var timeaa = nian + '-' + yue + '-' + tian
        paiban(timeaa, fid);
        worktime = timeaa

      })

    }
