<view class="helplist"  @tap="toggle(index)" v-for="(item, index) in dataList" :key="index">

<view class="helptitle"><text class="question" :class="[index%2=='1'?'yellow':'blue']">?</text>{{item.title}}

<text class="fa down" :class="[current==index?'fa-caret-up':'fa-caret-down']"></text></view>

export default {

data() {

return {

index : 0,

current : 0,

},

onLoad(e) {

this.getData();

},

getData(e) {

uni.request({

return;

}

this.dataList = ret.data.info;

console.log(this.dataList)
