微信小程序之一：动态添加view（view包含picker,input）

<view  wx:for="{{array}}"  wx:key="this" class="borderContainer">
  <view class="borderContainer1">
    <view class="firstBorder">
      <view class="firstBorderInput">
      <input maxlength="6" bindinput="persionInput{{index}}" wx:if="{{index==0}}" class="textArea" value="{{persionName0}}"></input>
        <input maxlength="6" bindinput="persionInput{{index}}" wx:if="{{index==1}}" class="textArea" value="{{persionName1}}"></input>
        <input maxlength="6" bindinput="persionInput{{index}}" wx:if="{{index==2}}" class="textArea" value="{{persionName2}}"></input>
        <input maxlength="6" bindinput="persionInput{{index}}" wx:if="{{index==3}}" class="textArea" value="{{persionName3}}"></input>
      </view>
      <view class="line" ></view>
      <view class="rightImageBorder">
        <picker bindchange="bottomdowm{{index}}" data-value="{{pickArray[index]}}" data-index="{{index}}" value="{{index}}" range="{{pickArray}}" class="pickBorder">
          <image src="/pages/me/houseOperation/creatFamily/image/button_down.png" class="rightImage"></image>
        </picker>
      </view>
    </view>
  </view>
  <view class="rightBorder">
    <input type="number" bindinput="persiontelInput{{index}}" placeholder="请输入成员号码" maxlength="11" class="cyinputtel"></input>
  </view>
</view>

View Code

　　这里所做的就是通过array动态添加view的功能，在为每个动态的picker以及input操作中，都是通过提取array的index操作来为其目标项添加值得操作，虽然这里动态添加的项不是很多，但是多个的话难免有点代码冗余。本人开发小程序不久，如有更好的思路以及做法请在下方留言，一起学习，虽然问题简单，但能够解决问题也是一件很非凡的事！！
