请问API：wx.getChannelsLiveInfo中，直播 feedId，直播 nonceId哪里来

代码如下 <video src="https://cdnzhike.vanke.com/online/videos/item/4hNBb4jt4mP8i2DFTrKpjhN3i8RGjs2Q.mp4" binderror='binderror'></video> binderror(e){ console.log('播放报错',e) } 代码视频文件40M，换个视频20M左右的视频链接又正常

少部分手机，cover-view与map两组件如果在不同的自定义组件，cover-view盖不住map，cover-view  position: fixed;怎么解决？ 下面截图手机型号，锤子手机也会。如果两个组件在同一个自定义组件里面cover-view可以覆盖map。但是两个组件分别在两个自定义组件里面，地图可以跟着页面滚动的，cover-view固定悬浮在视图窗口的右边，这样就盖不住了。 [图片]

给textarea动态添加class样式， <textarea class="addressInput {{addresstype<=37?'':'align-l'}}" auto-height="true" bindinput="inputAddress" placeholder="请输入家庭地址" placeholder-style="color: #757575;font-size:32rpx;" value="{{address}}" /> .addressInput { padding-right: 48rpx; color: #212121; max-width: 700rpx; min-width: 600rpx; text-align: right; } .addressInput.align-l { text-align: left; } 在模拟器上，文字可以靠右，换行时字体会靠左，在手机上却不行
