方法1：使用标签，可以将页面横向（或纵向）滚动到指定位置
无法滚动 将代码放在settimeout，nexttick里执行
<!-- 左边 -->
<scroll-view show-scrollbar="false" scroll-y="true" class="left-box"
:scroll-top="scrolllefttop" scroll-with-animation="true">
<view class="scroll-view-item" v-for="(item,index) in servicesleftlist" :key="item.id"
:id="'scroll' + activelefttab" :class="{'active':activelefttab==item.id}">
{{item.name}}
</view>
</scroll-view>
import {getservicestree} from "@/api/tree"
data(){
return {
servicesleftlist:[],
scrolllefttop：0,，//滚动位置
activelefttab:"" //选中的样式
}
}
getdata() {
//接口
getservicestree().then(res => {
this.servicesleftlist= res.data
res.data.foreach((item, ind) => {
settimeout(()=>{
uni.createselectorquery().in(this).select('#scroll' + item.id)
.boundingclientrect(res => {
scrolllefttop.value = 65 * ind; // 设置滚动条距离左侧的距离
}).exec()
},100)
})
})
}
方法二 使用uni.pagescrollto 使页面纵向滚到到指定位置
建议设置height为auto :height:auto
<view class="left-box" >
<view class="scroll-view-item" v-for="(item,index) in servicesleftlist" :key="item.id"
:class="{'active':activelefttab==item.id}" :id="textarea"+index>
{{item.name}}
</view>
</view>
//方法
uni.pagescrollto({
scrolltop: 0,
duration: 500，
selector: '#textarea5' //指定位置
});
方法三 用scroll-view描点
//左边 :scroll-top="scrolllefttop"
<scroll-view scroll-y="true" class="left-box" scroll-with-animation="true"
:scroll-into-view="tracingleftpoint">
<view class="scroll-view-item" v-for="(item,index) in servicesleftlist" :key="item.id"
:id="'scroll' + item.id" :class="{'active':activelefttab==item.id}">
{{item.name}}
</view>
</scroll-view>
//方法
data(){
retrun {
tracingleftpoint:"",//描点id
}
}
getdata() {
//接口
getservicestree().then(res => {
this.servicesleftlist= res.data
res.data.foreach((item, ind) => {
settimeout(()=>{
this.tracingleftpoint= 'scroll' + item.id
},200)
})
})
}
