2023-06-13 09:11:57 时间

大家好，又见面了，我是你们的朋友全栈君。

订单支付

分析

顶部改为”支付” 上方为地址,跳转至地址管理,可修改 下方为订单信息 最下方显示所需支付金额以及支付按钮,点击支付则支付成功跳转订单页 如果不支付则可以在我的订单内容查看该订单并且继续支付

代码实现

改变顶部导航内容"navigationBarTitleText": "支付" 界面:

<navigator url="/pages/addressList/addressList" class="user_info_row" wx:if="{ 
    {statu!='待发货'}}">
  <view class="user_info" wx:for="{ 
    {addressList}}" wx:if="{ 
    {item.statu==true}}" wx:key="index">
    <view>{
  
  {item.name}}</view>
    <view>{
  
  {item.city}}{
  
  {item.address}}</view>
  </view>
  <view class="user_phone">{
  
  {item.tel}}</view>
</navigator>

<view class="user_info_row" wx:if="{ 
    {statu=='待发货'}}">
  <view class="user_info" wx:for="{ 
    {address}}" wx:key="index">
    <view>{
  
  {item.name}}</view>
    <view>{
  
  {item.city}}{
  
  {item.address}}</view>
  </view>
  <view class="user_phone">{
  
  {item.tel}}</view>
</view>

<!--购物车的内容-->

  <view class="cart_main">
    <!--当cart数组不为0显示 -->

    <view class="cart_item" wx:for="{

js

  • payList：支付的信息,即支付的商品列表
  • addressList:所有的收货地址
  • sum:总金额
  • num:数量
  • orderid：订单id
  • statu:订单状态
  • address:所选择的收货地址

函数:

  • onLoad(options)页面加载执行,主要是提供订单信息
  • onshow()页面显示时执行,主要是进行判断该订单的状态并且进行赋值
  • payshop():支付函数
