小程序实现侧滑删除功能
本文实例为大家分享了小程序实现侧滑删除的具体代码，供大家参考，具体内容如下
1.页面布局
<view class='dialogue-box'>
<scroll-view scroll-y="true" style="height:{{winHeight-50}}px">
<view class='top-list'>
<view class='standard_text1'>#</view>
<view class='standard_text2'>积分项目</view>
<view class='standard_text3'>标准分</view>
<view class='standard_text4' bindtap='AddIntegrationProject'>
<view class='standard_btn'>+</view>
</view>
</view>
<view wx:if="{{lists.length>0}}">
<view class='top-list'>
<view wx:for="{{lists}}" wx:key="{{index}}" class='main_item'>
<view bindtouchstart="touchS" bindtouchmove="touchM" bindtouchend="touchE" data-index='{{index}}' style="{{item.txtStyle}}" class="inner txt">
<view class='standard_text1'>{{index+1}}</view>
<view class='standard_text2'>{{item.itemName}}</view>
<view class='standard_text3'>{{item.score}}分</view>
<view class='standard_text4'>
<image class='standard_icon' bindtap='editStanderClick' data-item='{{item}}' src='{{BaseURL}}uploadFile/groupImages/edit-h2.png'></image>
</view>
</view>
<view data-index="{{index}}" bindtap='delectOrganizationTeamScoreStandard' data-id='{{item.ID}}' class="inner del">删除</view>
</view>
</view>
</view>
<view class='No-data' wx:else>
<image src='{{BaseURL}}uploadFile/groupImages/No-data.png'></image>
<view class='No-text'>亲！暂无您的上月积分记录！</view>
</view>
</scroll-view>
</view>
