小程序多重遍历==小程序遍历数组中的数组

代码:  遍历 modelList 数组套数组

 

<view class=\'modelitem\' wx:for="{{modelList}}" data-order=\'{{item.name}}\' wx:key>
            <view class=\'modelitemTitle\' bindtap=\'modelitemTitle\' data-index="{{index}}">{{item.name}}</view>
            <block wx:if="{{item.shows}}">
              <view class=\'modelitem_item\' bindtap=\'modelitem_item\' data-name=\'{{itemTwo.name}}\' data-model=\'{{itemTwo.id}}\' wx:for="{{item.shopTruckModelEntityList}}" wx:key wx:for-item="itemTwo">
                {{itemTwo.name}}
              </view>
            </block>
          </view>


//小知识:(获取自定义属性)

modelitemTitle(e){

　　console.log(e.currentTarget.dataset.index

}

区分 vue自定义属性

<ul class="homeList">
                    <li v-for="(item, index) of homeList" 
                        :key="index"
　　　　　　　　　　　　　　　　:id="item.id"
                        @click="homeListClick(index,item.id)"
                        :class="{ \'bgcTwo\': item.type!=1, \'bgcOneSelected\': item.type==1&&(homeTicketIndex==index), \'bgcTwoSelected\': item.type!=1&&(homeTicketIndex==index) }">
                        <div class="homeItemTop" :class="{\'whiteColor\':homeTicketIndex==index}">
                            <img src="./img/dui.png" v-if="homeTicketIndex==index" alt="">
                            <img src="./img/yuan.png" v-if="homeTicketIndex!=index" alt="">
                            <p v-if="item.type==1" :class="{\'whiteColor\':homeTicketIndex==index}">{{item.name}}</p>
                            <p style="font-size:.88rem" :class="{\'whiteColor\':homeTicketIndex==index}" v-if="item.type!=1">{{item.dAmount}}<span>元 × {{item.countUsed}}张</span></p>
                        </div>
                        <p v-if="item.type==1" :class="[\'homeItemtitle\',{\'whiteColor\':homeTicketIndex==index}]">222</p>
                        <p v-if="item.type!=1" :class="[\'homeItemtitle\',{\'whiteColor\':homeTicketIndex==index}]">222</p>
                        <p :class="[\'timeLimit\',{\'whiteColor\':homeTicketIndex==index}]">2</p>
                        <div class="homeListBtn">{{item.price}}元购买</div>
                    </li>
                </ul>

直接函数拿:

homeListClick(index,item.id){}
