使用自定义按钮关闭layui的layer

$("#btnback").on("click", function () {
   var  indexback1111 = layer.open({
        title: "退回确认",
        area: ["600px", "330px"],
        type: 1,
        content: $('#divEdit'),
      success: function (layero, indexddddd) {
          $("#Remark").val("");
          layero.find("#btnClose1").on("click", function (e) {
              layer.close(indexback1111)
          });
        },
        end: function () {
            $("#divEdit").hide();
        }
    });
})

关键：必须要有end
