点击字母跳转不到位的问题：在<u-index-list>添加方法@select=“clickSelect“

锚点要加id，用对应的字母做为id值，

<u-index-anchor :id="key" :index="key"/>

<template><view><view class="search"><u-search v-model="keywords" @custom="search" @search="search" :margin="'0px 0 0 0'"></u-search></view><view class="wrap "><u-index-list class="container" :offsetTop="190" :scrollTop="scrollTop" @select="clickSelect":index-list="indexList"><view class="personal-listitem" v-for="(key, idx) in indexList" :key="idx" :use-slot="true"><view class="personal-listitem" :use-slot="true" data-top="idx"><u-index-anchor :id="key" :index="key"/><view class="list-cell" v-for="(item, index) in listByLetter[idx]" :key="index"@click="navTo('')"><view class="user-images-new">{{ key }}</view><view class="user-name"><span>{{ item}}</span><span class="user-other">{{ key }}</span></view></view></view></view></u-index-list><u-divider>已经到底了</u-divider></view></view>
</template>

 字母点击事件

  clickSelect(e) {//从当前位置到达目标位置console.log(">>>当前节点", e, this.scrollTop)try {uni.createSelectorQuery().select('#' + e).boundingClientRect((data) => {console.log(">>data", data)//目标位置的节点：类或者iduni.createSelectorQuery().select('.container').boundingClientRect((res) => {console.log(data, res)console.log(">>res.top", res.top)//最外层盒子的节点：类或者idthis.$nextTick(() => {uni.pageScrollTo({scrollTop: data.top - res.top,// selector: '#' + e,duration: 100 //app端这个必须设置成0})})}).exec()}).exec()} catch (e) {}},

点击跳转：

 出现字母乱跳：indexlist传入的数组字母，没跟真实的左侧的列表匹配上。

:index-list="indexList",如下例子，遍历之后右侧应该不是26个字母，是a,b,d,w,x,y这几个。

let indexList=[
{"letter":"a","data":["啊","爱","按"]},
{"letter":"b","data":["不"]},
{"letter":"d","data":["懂"]},
{"letter":"w","data":["我"]},
{"letter":"x","data":["县","选"]},
{"letter":"y","data":["呀","已"]}]
