使用工具:
1.微信Web开发者工具
2.Visual Studio 2019
前端采用color UI,后端采用c# .net
过程中的几个重点点记录
1.color UI使用
下载colorUI以后
将icon.wxss、colorui.wxss拷贝至项目根目录
在app.wxss中导入文件
<view class="cu-form-group"> <view class="picture_list"> <view wx:for="{{upload_picture_list}}" class="picture_item" wx:key="{{index}}"> <image wx:if="{{item.upload_percent < 100}}" src="{{item.path}}" mode="aspectFill"></image> <image wx:if="{{item.upload_percent == 100}}" src="{{item.path_server}}" mode="aspectFill"></image> <view class="upload_progress" wx:if="{{item.upload_percent < 100}}" data-index="{{index}}" bindtap="previewImg">{{item.upload_percent}}%</view> <text class=‘del‘ bindtap=‘deleteImg‘ data-src=‘{{image}}‘ style=‘display:{{isDel}}‘ data-index="{{index}}">×</text> </view> <view class=‘picture_item‘> <view class="add-image" bindtap=‘uploadpic‘> <text>+</text> </view> </view> </view> </view> <view class="cu-form-group"> <button bindtap=‘uploadimage‘ class=‘yes-upload‘>上传图片</button> </view>
js代码
