|
||||
## 功能特点
|
||||
|
||||
- ✅ 五级联动选择（省/市/区/街道/社区）
|
||||
- ✅ 自动级联更新
|
||||
- ✅ 支持取消和确认操作
|
||||
- ✅ 底部弹出式交互
|
||||
- ✅ 支持自定义标题
|
||||
- ✅ 返回完整的地址信息和各级代码
|
||||
|
||||
## 使用方法
|

||||
### 1. 引入组件
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<view>
|
||||
<button @click="openPicker">选择地址</button>
|
||||
<area-cascade-picker ref="areaPicker"></area-cascade-picker>
|
||||
</view>
|
||||
</template>
|
||||
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
import AreaCascadePicker from '@/components/area-cascade-picker/area-cascade-picker.vue'
|
||||
|
||||
const areaPicker = ref(null)
|
||||
</script>
|
||||
```
|
||||
|
||||
### 2. 打开选择器
|
||||
|
||||

const openPicker = () => {
|
||||
areaPicker.value?.open({
|
||||
title: '选择地址',
|
||||
maskClick: true,
|
||||
success: (addressData) => {
|
||||
console.log('选择的地址：', addressData)
|
||||
// 处理选择结果
|
||||
},
|
||||
cancel: () => {
|
||||
console.log('取消选择')
|
||||
},
|
||||
change: (addressData) => {
|
||||
console.log('地址变化：', addressData)
|
||||
}
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
name: "喀什市"
|
||||
},
|
||||
street: {
|
||||
code: "65310101",
|
||||
name: "学府街道"
|
||||
},
|
||||
community: {
|
||||
code: "6531010101",
|
||||
name: "学府社区居委会"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### close()
|
||||
|
||||

||||
{
|
||||
code: '650000', // 行政区划代码
|
||||
name: '新疆维吾尔自治区', // 名称
|
||||
children: [ // 下级行政区
|
||||
{
|
||||
code: '653100',
|
||||
name: '喀什地区',
|
||||
children: [
|
||||
{
|
||||
code: '653101',
|
||||
name: '喀什市',
|
||||
children: [
|
||||
{
|
||||
code: '65310101',
|
||||
name: '学府街道',
|
||||
children: [
|
||||

}
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
```
|
||||

## 性能优化
|
||||
|
||||
### 懒加载方案（已实现）⭐
|
||||
|
||||
组件已实现**懒加载**机制，大幅优化90M+地址数据的加载性能：
|
||||
|
||||
#### 核心优化
|
||||
|
||||
1. **首次加载**：只加载省份列表（< 1MB，3-5秒完成）
|
||||
2. **按需加载**：用户选择省份后，再加载该省份的详细数据（2-5MB，5-10秒）
|
||||
3. **智能缓存**：已加载的数据会缓存，切换省份时秒开
|
||||
4. **自动降级**：如果服务器不支持分片接口，自动从完整数据中提取
|
||||
|
||||
#### 性能对比
|
||||
|
||||
| 场景 | 优化前 | 优化后（懒加载） |
|
||||
|------|--------|------------------|
|
||||
| 首次打开选择器 | 加载90M+（3-5分钟） | 加载省份列表（< 1MB，3-5秒） |
|
||||
| 选择省份 | 无需加载 | 加载该省份数据（2-5MB，5-10秒） |
|
||||
| 切换省份 | 无需加载 | 从缓存读取（< 1秒） |
|
||||
|
||||
#### 使用方式
|
||||
|
||||
组件已自动使用懒加载模式，无需修改调用代码：
|
||||
|
||||
```javascript
|
||||
// 正常使用，自动懒加载
|
||||
areaPicker.value?.open({
|
||||
success: (addressData) => {
|
||||
console.log('选择的地址：', addressData)
|
||||
}
|
||||
})
|
||||
|
||||
// 强制刷新数据（忽略缓存）
|
||||
areaPicker.value?.open({
|
||||
forceRefresh: true, // 强制从服务器重新加载
|
||||
success: (addressData) => {
|
||||
console.log('选择的地址：', addressData)
|
||||
}
|
||||
})
|
||||
|
||||
// 清除缓存
|
||||
areaPicker.value?.clearCache()
|
||||
```
|
||||
|
||||
### 服务器分片接口（最佳方案）🚀
|
||||
|
||||
如果服务器可以提供分片接口，性能会进一步提升。详见：[地址数据懒加载优化方案.md](../../docs/地址数据懒加载优化方案.md)
|
||||
|
||||
需要的接口：
|
||||
- 省份列表接口：`/address_provinces.json`（轻量级，< 1MB）
|
||||
- 省份详情接口：`/address_province_{code}.json`（按需加载，每个2-5MB）
|
||||
|
||||
### 缓存机制
|
||||
|
||||
1. **自动缓存**：已加载的数据会自动缓存到 IndexedDB（H5）或 uni.storage（小程序）
|
||||
2. **缓存有效期**：默认7天，过期后自动重新加载
|
||||
3. **离线支持**：网络失败时自动使用缓存数据
|
||||
4. **存储方案**：优先使用 IndexedDB，自动降级到 uni.storage
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据来源**：当前从远程JSON文件加载，生产环境建议接入后端API
|
||||
2. **数据更新**：如需接入后端API，修改 `loadAreaData` 方法即可
|
||||
3. **性能优化**：已集成缓存机制，首次加载后速度大幅提升
|
||||
4. **兼容性**：支持 H5、微信小程序等多端
|
||||
5. **存储限制**：小程序环境有存储限制，如遇问题会自动清理旧缓存
|
||||
|
||||
## 接入后端API
|
||||
|
||||
在组件的 `loadAreaData` 方法中取消注释并配置API：
|
||||
|
||||
```javascript
|
||||
async loadAreaData() {
|
||||
try {
|
||||
const resp = await uni.request({
|
||||
url: '/app/common/area/cascade',
|
||||
method: 'GET'
|
||||
});
|
||||
if (resp.statusCode === 200 && resp.data && resp.data.data) {
|
||||
this.areaData = resp.data.data;
|
||||
return;
|
||||
}
|
||||
} catch (error) {
|
||||
console.error('加载地区数据失败:', error);
|
||||
}
|
||||
|
||||
// 失败时使用模拟数据
|
||||
this.areaData = this.getMockData();
|
||||
}
|
||||
```
|
||||
|
||||
