大家好，又见面了，我是你们的朋友全栈君。

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'}}">

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
