1.通過wx:if判斷給渲染層設置不同的樣式

// wx:for="{{drawdata}}" wx:for-item="item" wx:key="id" 
// 循環(huán)的數(shù)據(jù)
<block wx:if="{{item.money > 0}}">
      <view class="draw-right" style="color:#E60012">
        {{item.money}}
      </view>
  </block>
 <block wx:elif="{{item.money < 0}}">
      <view class="draw-right" style="color:#6ABE8A">
        {{item.money}}
      </view>
 </block>

**效果如下
