WeChat mini program mall development code to implement user delivery address management page

The content of this article is about the code for implementing the user delivery address management page in the development of WeChat applet mall. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you. .

See the effect

Development plan

1 , layout the delivery address list and the new delivery address page

2, realize the three-level linkage function of province, city and county

3, use cache management data

1. Shipping address list management

addressList.wxml

<scroll-view class="scroll" scroll-y="true">
  <view wx:for="{{addressList}}">
    <view class="product-name-wrap">
      <view class="ui-list-item-info">{{item.consignee}}
        <text decode="{{true}}" space="{{true}}">  </text> {{item.mobile}}
      </view>
      <view class="ui-list-item-address">
        {{item.address}}
      </view>
      <view class="ui-list-item-time">
        <p>{{item.transportDay}}</p>
        <p class="ui-list-item-del" data-id="{{index}}" bindtap="delAddress">删除</p>
      </view>
      <view class="separate"></view>
    </view>
  </view>
</scroll-view>
<view class="add-address" bindtap="addAddress">
  <image class="add-img"  src="../../images/add.png"></image>新增地址
</view>

addressList.json

{
  "navigationBarTitleText": "管理地址"
}

addressList.js

Page({
 
  /**
   * 页面的初始数据
   */
  data: {
    addressList:[]
  },
  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    var arr = wx.getStorageSync('addressList') || [];
    console.info("缓存数据：" + arr);
    // 更新数据  
    this.setData({
      addressList: arr
    });
  },
 
  /**
   * 生命周期函数--监听页面显示
   */
  onShow: function () {
    this.onLoad();
  },
  addAddress:function(){
    wx.navigateTo({ url: '../address/address' });
  },
  /* 删除item */
  delAddress: function (e) {
    this.data.addressList.splice(e.target.id.substring(3), 1);
    // 更新data数据对象  
    if (this.data.addressList.length > 0) {
      this.setData({
        addressList: this.data.addressList
      })
      wx.setStorageSync('addressList', this.data.addressList);
    } else {
      this.setData({
        addressList: this.data.addressList
      })
      wx.setStorageSync('addressList', []);
    }
  }
})

2. Add receipt information
