<view class=“weui-cell” wx:for="{{imagedata}}" wx:key="{{item.F_Path}}" data="{{item}}" style=“font-size:28rpx;”>
<view class=“weui-uploader__file” bindtap=“previewoldImage” id="{{item.F_Path}}">
<image src="{{item.F_Path}}" mode=“aspectFit”></image>
</view>
<view wx:if="{{item.F_CZY==MyName && item.F_Date==CurDate}}" id="{{item.F_Path}}" bindtap=“delImage”>
删除
</view>
</view>
请问我以前这样写是没问题的,现在变成 这种错误了,是什么问题 wx:key="{{item.F_Path}}" does not look like a valid key name (did you mean wx:key=“F_Path” ?)
