如何循环出数组中之地当的某一条数据？

<block wx:for="{{audios}}" wx:key="name">  <view wx:if="{{item.type == 'a'}}">{{item.a}}<view>block>	

<view wx:for="{{audios}}" wx:key="{{item.idex}}">  <view wx:if="{{item.type == 'a'}}">      <view>{{item.name}}view>   view>view>

先filter一下或者在wx:for循环里面做判断

const res = audios.filter(function(value, index, array) {  if ('a' === value.type) {    return true  }})

<view wx:for="audios" wx:key="idex">  <view wx:if="{{item.type == 'a'}}">view>view>

audios[0]

<block wx:if="{{item.type=='a'}}">block>
