一、项目展示

这是一款简易的记账本小程序

用户可以记录自己平日里的借入和借出的金额

此外可以手动删除记录（右滑记录）

二、首页

首页划分为资产金额和资产记录两部分组成

相关代码如下：

<import class="lazy" data-src="list/list.wxml" />
<view class="container">
  <view class="total">
    <view class="total-money">￥{{totalMoney}}</view>
    <span class="total-word">总资产</span> 
    <view class="total-list">
      <view id="totalOut" class="total-out" catchtap="onDetailTap">
        <view class="total-out-money">-￥{{outMoney}}</view>
        <view class="total-out-number">借出{{outNumber}}笔</view>
      </view>
      <span class=" shuxian"></span> 
      <view id="totalIn" class="total-in" catchtap="onDetailTap">
        <view class="total-in-money">+￥{{inMoney}}</view>
        <view class="total-in-number">借入{{inNumber}}笔</view>
      </view>
    </view>
  </view>
  <view class="add" catchtap="onEditTap">
    <view class="image"></view>
    记一笔</view>
  <view class="show ">
    <span wx:if="{{detailInfo}}">空空如也，快去记上一笔吧</span> 
    <view class="list-container" wx:else>
      <block wx:for="{{data}}" wx:for-item="item" wx:for-index="index">
        <view class="outter">
          <view class="list" catchtouchstart="onTouchStart" catchtouchend="onTouchEnd" catchtouchmove="onTouchMove" style="right:{{item.slideX}}" data-listId="{{index}}">
            <view class="list-people ">{{item.inputPeople}}</view>
            <view class="list-info ">{{item.inputInfo}}</view>
            <view class="list-money-date ">
              <view class="list-money colorRed" wx:if="{{item.radioGroup=='-'?true:false}}">{{item.radioGroup+"￥ "+item.inputMoney}}</view>
              <view class="list-money colorGreen" wx:else>{{item.radioGroup+"￥ "+item.inputMoney}}</view>
              <view class="list-date ">{{"["+item.date+"]"}}</view>
            </view>
          </view>
          <view class="delete" catchtap="onDeleteTap" data-deleteId="{{index}}">
            <text class="delete-text ">删除</text>
          </view>
        </view>
      </block>
    </view>
  </view>
</view>
