微信小程序定制加判断再确实是否显示textarea组件，

时间：2019-05-03 来源：小程序工厂

<br><block wx:if="{{content}}"><br>    <textarea class="weui-textarea" placeholder="" value='{{content}}'style="height: 3.3em" /><br></block><br>      <cover-view class='weui-btn-area'><br>            <button class="weui-btn" type="primary">确定发货</button><br>          </cover-view><br><br>加判断再确实是否显示textarea组件，coverview层级无效？是因为渲染的问题导致的吗？有没有更好的解决方法，目前这里想到的也只是，不加判断或者不适用textarea，使用class="weui-textarea" 样式<br><img src="http://img.xcxgc.com/112839la6zp5upssdpp403.jpeg" border=0 ><br><br><br><br><br><br><br><br> <img src="http://img.xcxgc.com/112840r6yjg68u7qy669q0.jpeg" border=0 ><br><br><br><br><br><br><br><br><h3>微信小程序开发问题解答</h3><br><div class="toux"><span class="huifu">微信小程序开发者回答：</span><p>  <br>cover-view想覆盖textarea？不可以！cover-view可覆盖的原生组件包括map、video、canvas、camera、live-player、live-pusher，只支持嵌套cover-view、cover-image<br><br>
