view 页面

<view class="contract">    <picker mode="multiSelector" bindchange="bindMultiPickerChange" bindcolumnchange="bindMultiPickerColumnChange" value="{{multiIndex}}" range="{{multiArray}}">        <view class='panel-min'>            <view class='flex'>                <view class='panel-title'>所属社区</view>                <view class='panel-text-ms'>                {{multiArray[0][multiIndex[0]]}},{{multiArray[1][multiIndex[1]]}}                   </view>            </view>            <text class='arrow'></text>        </view>    </picker></view>

本例子只有一级,二级三级，后面做拼接

{{multiArray[0][values[0]]}} ,{{multiArray[1][values[0]]}},{{multiArray[2][values[0]]}}
