vue实现滚动到底部翻页效果（pc端）
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">【{{de||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.$refs.scrollTopList.scrollHeight,
height = 50; //根据项⽬实际定义
if(scrollTop +clientHeight >= scrollHeight - height){
if(this.pageSize > al){
return false
}else{
this.pageSize = this.pageSize +10 //显⽰条数新增
}
}else{
return false
}
},
method中写节流函数
throttle(func, wait) {
let lastTime = null
let timeout
return () => {
let context = this;
let now = new Date();
let arg = arguments;
if (now - lastTime - wait > 0) {
if (timeout) {
clearTimeout(timeout)
timeout = null
}
func.apply(context, arg)
lastTime = now
} else if (!timeout) {
timeout = setTimeout(() => {
func.apply(context, arg)
}, wait)
}
}
},
mounted中调⽤
mounted(){
this.$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"
jquery滚动条滚动到底部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">{{de != null ?de:"/"}}</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 (de == 200) {
this.devicePageTotal = al;
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 = at(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: "",
