直接上干货

api.addEventListener({             name: 'scrolltobottom',             extra: {                 threshold: 0             }         }, function(ret, err) {           index += 1;           var data = {               categoryId: 0,               pageNum: index,               pageSize: 10           }           ajaxRequest('/api/Shop/GoodsListFromCategory?', 'get', data, true, function(ret) {               if (ret.code == 200) {                 if (ret.res.data.count == 0) {                   toast("没有更多数据了！")                 }else {                   main.list = main.list.concat(ret.res.data.list);                 }               } else {                   toast(ret.res.msg)               }           })         });
