pc端vue 滾動到底部翻頁 效果,具體內容如下所示:
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:
先寫滾動事件
handleScroll(){ let scrollTop = this.$refs.scrollTopList.scrollTop, clientHeight = this.$refs.scrollTopList.clientHeight, scrollHeight = this.$refs.scrollTopList.scrollHeight, height = 50; //根據項目實際定義 if(scrollTop +clientHeight >= scrollHeight - height){ if(this.pageSize > this.total){ return false }else{ this.pageSize = this.pageSize +10 //顯示條數新增 this.getpageList() //請求列表list 接口方法 } }else{ return false } },
method中寫節流函數
throttle(func, wait) { let lastTime = null let timeout return () => { let context = this; let now = new Date(); let arg = arguments; if (now - lastTime - wait > 0) { if (timeout) { clearTimeout(timeout) timeout = null } func.apply(context, arg) lastTime = now } else if (!timeout) { timeout = setTimeout(() => { func.apply(context, arg) }, wait) } } },
mounted中調用
mounted(){ this.$refs.scrollTopList.addEventListener("scroll",this.throttle(this.handleScroll,500),true) },
//-------------------------------------------------------------------------------------------第二種寫法
html:
添加滾動事件
<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: //根據實際項目取 overflow:auto //必須 不然判斷有問題 }
css 定義
js
寫入滾動事件
scrollEvent(e) { if (e instanceof Event) { let el = e.target; let scrollTop = el.scrollTop; // 獲取可視區的高度 let clientHeight = el.clientHeight; // 獲取滾動條的總高度 let scrollHeight = el.scrollHeight; let height = 50; //到底了 // console.log(this.deviceListIsLoad, this.deviceListIsFinish); // console.log(scrollTop, clientHeight, scrollHeight); //是否繼續加載且已完成加載 if ( scrollTop + clientHeight >= scrollHeight && this.deviceListIsLoad && !this.deviceListIsFinish ) { // 把距離頂部的距離加上可視區域的高度 等于或者大于滾動條的總高度就是到達底部 this.deviceListIsLoad = true; console.log("到底了"); setTimeout(() => { this._deviceListPage(); }, 1000); } }
請求列表的處理
_deviceListPage() { let params = { pageSize: this.devicePageSize, pageNum: this.devicePageNum, kw: "", //查詢條件(通配查詢條件) type: this.deviceType, //設備類型(下拉)2.1.6接口獲取 code: this.deviceCode, //設備編號 areaId: this.deviceareaId, //位置區域 status: this.deviceStatus, //狀態 1:在線(正常),0:未激活,2已離線,3.告警 imei: "" //imei編號 }; 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("沒有數據"); //沒有數據 this.deviceListnodata = true; this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "暫無數據"; return false; } this.deviceList = this.deviceList.concat(res.body.datas); // console.log(this.devicePageNum, this.devicePageTotalPages); if (this.devicePageNum == this.devicePageTotalPages) { //沒有更多 this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "沒有更多了~"; // console.log("沒有更多了"); } else { // console.log("下一頁"); //下一頁 this.deviceListIsLoad = true; this.deviceListIsFinish = false; this.devicePageNum++; this.deviceTip = "正在加載中~"; } // console.log("deviceList", this.deviceList); } else { // this.deviceList = []; this.deviceListIsLoad = false; this.deviceListIsFinish = true; this.devicePageNum = 1; this.deviceTip = "數據加載失敗~"; } }); },
return中的定義
devicePageSize: 10, //每頁顯示 devicePageNum: 1, //當前頁 devicePageTotal: 0, //總條數 devicePageTotalPages: 0, //總頁數 deviceListIsFinish: false, //是否加載完成 deviceListIsLoad: false, //是否加載更多 deviceListnodata: false, //是否有數據 deviceTip: "",
