配置

{"path": "list/course-list","style": {"navigationBarTitleText": "课程列表","enablePullDownRefresh": true,"onReachBottomDistance": 150}}

上拉拉触底钩子

onReachBottom() {var that = this;if (that.groupPage * that.showNo - that.groupTotal < 0) {setTimeout(function () {that.groupPage += 1;that.getCommodityList();//请求下页数据}, 200);} else {this.isfinish = true;console.log("数据已经加载完成")}},

data值

data() {return {imgBaseWebUrl: this.$imgBaseWebUrl,serverFileUrl: app.globalData.ossFileServer,loading: '加载中',shopList: [],flowList: [],leftList: [],dictClassifyId: "",searchText: '',//搜索关键字groupPage: 1, //列表部分当前页码groupTotal: 0, //列表部分总页码showNo: 10,//每页显示条数isfinish: false,//列表数据是否加载完成reqIng: true,//数据请求中};

getCommodityList请求数据：

//获取所有商品getCommodityList: function () {let that = this;let url = "/classSchedule/page";that.reqIng = true;that.isfinish = false;let params;if(this.searchText){params={page: that.groupPage,title:this.searchText}}else{params={page: that.groupPage}}// console.log("当前请求页码", that.groupPage)this.$http.post(url, params).then((res) => {uni.hideLoading();console.log('后端', res);if (res.code == 200) {that.flowList=res.rows;console.log('取到的数据', that.flowList)if (that.showNo >= res.total) {//只有一页数据that.isfinish = true;}} else {uni.showToast({title: res.message,icon: "none",});}that.reqIng = false;}).catch((i) => {}).finally(() => {uni.hideLoading();});},
