若依项目的通讯录列表,点击字母跳转功能
跳转事件,手动添加。
锚点要加id,用对应的字母做为id值,
- <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>
根据锚点的id获取到对应的元素,然后页面滚动到锚点top,这样可以点击滚动到对应的item
- 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id
- uni
- .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id
- this.$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"]}]
