+# 楼层选择组件 (FloorSelector)
+
+## 功能描述
+
+楼层选择组件是一个三层级联选择器，用于选择楼层、区域和单元。组件会根据接口返回的树形数据自动渲染选择项。
+
+## 接口数据格式
+
+组件期望的接口返回格式：
+
+```json
+{
+  "msg": "操作成功",
+  "code": 200,
+  "data": [
+    {
+      "id": "12",
+      "label": "寒山寺",
+      "type": 1,
+      "children": [
+        {
+          "id": "1",
+          "label": "1F",
+          "type": 2,
+          "children": [
+            {
+              "id": "23",
+              "label": "A区",
+              "type": 3,
+              "children": [
+                {
+                  "id": "16",
+                  "label": "A01",
+                  "type": 4,
+                  "children": null
+                }
+              ]
+            }
+          ]
+        }
+      ]
+    }
+  ]
+}
+```
+
+## 组件属性 (Props)
+
+| 属性名 | 类型 | 默认值 | 说明 |
+|--------|------|--------|------|
+| defaultFloorId | String | '' | 默认选中的楼层ID |
+| defaultAreaId | String | '' | 默认选中的区域ID |
+| defaultUnitId | String | '' | 默认选中的单元ID |
+
+## 事件 (Events)
+
+| 事件名 | 参数 | 说明 |
+|--------|------|------|
+| selection-change | { floor, area, unit } | 选择发生变化时触发 |
+
+## 方法 (Methods)
+
+| 方法名 | 参数 | 返回值 | 说明 |
+|--------|------|--------|------|
+| getCurrentSelection | - | Object | 获取当前选中信息 |
+| resetSelection | - | - | 重置选择到默认状态 |
+
+## 使用示例
+
+### 基础使用
+
+```vue
+<template>
+  <FloorSelector @selection-change="handleSelectionChange" />
+</template>
+
+<script>
+import FloorSelector from './compositons/floorSelector.vue'
+
+export default {
+  components: {
+    FloorSelector
+  },
+  methods: {
+    handleSelectionChange(selection) {
+      console.log('选择变化:', selection)
+      // selection 包含 { floor, area, unit }
+    }
+  }
+}
+</script>
+```
+
+### 设置默认选中项
+
+```vue
+<template>
+  <FloorSelector
+    :default-floor-id="'1'"
+    :default-area-id="'23'"
+    :default-unit-id="'16'"
+    @selection-change="handleSelectionChange"
+  />
+</template>
+```
+
+### 获取当前选择
+
+```vue
+<template>
+  <FloorSelector ref="floorSelector" />
+  <button @click="getSelection">获取选择</button>
+</template>
+
+<script>
+export default {
+  methods: {
+    getSelection() {
+      const selection = this.$refs.floorSelector.getCurrentSelection()
+      console.log('当前选择:', selection)
+    }
+  }
+}
+</script>
+```
+
+## 样式定制
+
+组件使用了以下主要颜色：
+
+- 背景色: `#FFFBF5`
+- 边框色: `#C7A26D`
+- 未选中按钮: `#F5E6D3`
+- 选中按钮: `#8B4513`
+- 文字颜色: `#695347`
+
+可以通过修改组件的样式来调整外观。
+
+## 注意事项
+
+1. 组件会自动调用 `/app/memorial/listTree` 接口获取数据
+2. 选择楼层时会自动选中第一个区域
+3. 选择区域时会自动选中第一个单元
+4. 如果接口返回空数据，会显示空状态
+5. 网络异常时会显示错误提示
