刷新tab当前页面

        //重新渲染页面
        window.applyJourney = function(){
            var goodsid = $("#data-id").val();

            $.ajax({
                url:"{:url('ShopJourneyData/read')}",
                data:{
                    id:goodsid
                },
                success:function(res){
                    $("#mode2").empty().append(res);
                }
            })
        }
