pc端vue 滚动到底部翻页 效果，具体内容如下所示：

html：

<div class="list" ref="scrollTopList"> <div class="listsmall" v-for="(item,index) of list" :key="index" @click="getDeviceInfo(item.id)"> <span class="state" :class="{'state1':item.status==1,'state0':item.status==0,'state2':item.status==2,'state3':item.status==3}"></span> <span class="text textcolor">【{{item.code||item.name}}】</span> <span class="text">{{item.name}}</span> </div> </div>

js:

先写滚动事件

handleScroll(){ let scrollTop = this.$refs.scrollTopList.scrollTop, clientHeight = this.$refs.scrollTopList.clientHeight, scrollHeight = this.$refs.scrollTopList.scrollHeight, height = 50; //根据项目实际定义 if(scrollTop +clientHeight >= scrollHeight - height){ if(this.pageSize > this.total){ return false }else{ this.pageSize = this.pageSize +10 //显示条数新增 this.getpageList() //请求列表list 接口方法 } }else{ return false } },

method中写节流函数

throttle(func, wait) { let lastTime = null let timeout return () => { let context = this; let now = new Date(); let arg = arguments; if (now - lastTime - wait > 0) { if (timeout) { clearTimeout(timeout) timeout = null } func.apply(context, arg) lastTime = now } else if (!timeout) { timeout = setTimeout(() => { func.apply(context, arg) }, wait) } } },

mounted中调用

mounted(){this.$refs.scrollTopList.addEventListener("scroll",this.throttle(this.handleScroll,500),true)},

//-------------------------------------------------------------------------------------------第二种写法

html:

添加滚动事件

<div class="tablelist-box" @scroll="scrollEvent($event)"> <div class="tablelist" :class="{'active':listDevicesDetailIndex==index}" v-for="(item,index) of deviceList" :key="index" v-if="deviceList.length !== 0" @click="deviceDetail(item,index)" > <span class="tablelist-status"> <i :class="{zx:item.status==1,lx:item.status==2, wjh:item.status==0,gj:item.status==3}" ></i> </span> <span class="tablelist-bg">{{item.code != null ?item.code:"/"}}</span> </div> <div class="list-more" v-show="!deviceListIsFinish">{{deviceTip}}</div> <div class="list-more" v-show="deviceListIsFinish">{{deviceTip}}</div> </div>

css:

tablelist-box{ height: //根据实际项目取 overflow:auto //必须 不然判断有问题}

css 定义

js

写入滚动事件

scrollEvent(e) { if (e instanceof Event) { let el = e.target; let scrollTop = el.scrollTop; // 获取可视区的高度 let clientHeight = el.clientHeight; // 获取滚动条的总高度 let scrollHeight = el.scrollHeight; let height = 50; //到底了 // console.log(this.deviceListIsLoad, this.deviceListIsFinish); // console.log(scrollTop, clientHeight, scrollHeight); //是否继续加载且已完成加载 if ( scrollTop + clientHeight >= scrollHeight && this.deviceListIsLoad && !this.deviceListIsFinish ) { // 把距离顶部的距离加上可视区域的高度 等于或者大于滚动条的总高度就是到达底部 this.deviceListIsLoad = true; console.log("到底了"); setTimeout(() => { this._deviceListPage(); }, 1000); } }

请求列表的处理

_deviceListPage() { let params = { pageSize: this.devicePageSize, pageNum: this.devicePageNum, kw: "", //查询条件（通配查询条件） type: this.deviceType, //设备类型（下拉）2.1.6接口获取 code: this.deviceCode, //设备编号 areaId: this.deviceareaId, //位置区域 status: this.deviceStatus, //状态 1：在线（正常），0：未激活，2已离线，3.告警 imei: "" //imei编号 }; deviceListPage(params).then(res => { if (res.code == 200) { this.devicePageTotal = res.body.total; this.devicePageSize = res.body.pageSize; this.devicePageNum = res.body.pageNum; this.devicePageTotalPages = parseInt( (this.devicePageTotal + this.devicePageSize - 1) / this.devicePageSize ); if (this.devicePageTotal == 0) { // console.log("没有数据"); //没有数据 this.deviceListnodata = true; this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "暂无数据"; return false; } this.deviceList = this.deviceList.concat(res.body.datas); // console.log(this.devicePageNum, this.devicePageTotalPages); if (this.devicePageNum == this.devicePageTotalPages) { //没有更多 this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "没有更多了~"; // console.log("没有更多了"); } else { // console.log("下一页"); //下一页 this.deviceListIsLoad = true; this.deviceListIsFinish = false; this.devicePageNum++; this.deviceTip = "正在加载中~"; } // console.log("deviceList", this.deviceList); } else { // this.deviceList = []; this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "数据加载失败~"; } }); },

return中的定义

devicePageSize: 10, //每页显示 devicePageNum: 1, //当前页 devicePageTotal: 0, //总条数 devicePageTotalPages: 0, //总页数 deviceListIsFinish: false, //是否加载完成 deviceListIsLoad: false, //是否加载更多 deviceListnodata: false, //是否有数据 deviceTip: "",
