+# UserSelect 用户选择组件
+
+## 功能特性
+
+- ✅ 支持双栏选择器布局
+- ✅ 支持搜索功能（左右两侧独立搜索）
+- ✅ 三种操作方式：双击、勾选+按钮、全部按钮
+- ✅ **支持滚动分页加载**（性能优化）
+- ✅ 支持传入静态数据或API方法
+- ✅ 完全封装的样式和逻辑
+
+## Props 配置
+
+| 参数 | 类型 | 默认值 | 说明 |
+|------|------|--------|------|
+| visible | Boolean | false | 控制弹窗显示/隐藏 |
+| mode | 'add' \| 'remove' | 'add' | 选择模式 |
+| title | String | '人员选择' | 弹窗标题 |
+| leftTitle | String | '可选人员' | 左侧面板标题 |
+| rightTitle | String | '已选人员' | 右侧面板标题 |

+| **pageSize** | Number | 20 | **每页数量** |
+
+## Events 事件
+
+| 事件名 | 参数 | 说明 |
+|--------|------|------|
+| update:visible | (value: boolean) | 更新弹窗显示状态 |
+| confirm | (users: UserVO[]) | 确认提交，返回选中的用户列表 |
+| cancel | - | 取消操作 |
+
+## 使用方式
+
+### 方式一：传入静态数据（适合数据量少的场景）
+
+```vue
+<template>
+  <UserSelect
+    v-model:visible="showSelector"
+    mode="add"
+    title="选择用户"
+    :available-users="allUsers"
+    :initial-target-users="[]"
+    @confirm="handleConfirm"
+  />
+</template>
+
+<script setup lang="ts">
+import { ref } from 'vue';
+import { UserSelect } from '@/components';
+import type { UserVO } from '@/types';
+
+const showSelector = ref(false);
+const allUsers = ref<UserVO[]>([]);
+
+function handleConfirm(selectedUsers: UserVO[]) {
+  console.log('选中的用户:', selectedUsers);
+  showSelector.value = false;
+}
+</script>
+```
+
+### 方式二：使用分页加载（推荐，适合数据量大的场景）
+
+```vue
+<template>
+  <UserSelect
+    v-model:visible="showSelector"
+    mode="add"
+    title="选择用户"
+    :use-pagination="true"
+    :fetch-api="userApi.getUserPage"
+    :filter-params="filterParams"
+    :page-size="20"
+    :loading="saving"
+    @confirm="handleConfirm"
+  />
+</template>
+
+<script setup lang="ts">
+import { ref } from 'vue';
+import { UserSelect } from '@/components';
+import { userApi } from '@/apis/system';
+import type { UserVO } from '@/types';
+
+const showSelector = ref(false);
+const saving = ref(false);
+const filterParams = ref({
+  // 可以添加额外的过滤条件
+  status: 0
+});
+
+async function handleConfirm(selectedUsers: UserVO[]) {
+  saving.value = true;
+  try {
+    // 处理业务逻辑
+    for (const user of selectedUsers) {
+      await someApi.addUser(user.id);
+    }
+    showSelector.value = false;
+  } finally {
+    saving.value = false;
+  }
+}
+</script>
+```
+
+### 方式三：混合模式（添加模式用分页，删除模式用静态）
+
+```vue
+<template>
+  <UserSelect
+    v-model:visible="showSelector"
+    :mode="selectorMode"
+    :title="selectorMode === 'add' ? '添加人员' : '删除人员'"
+    :available-users="selectorMode === 'remove' ? currentUsers : []"
+    :use-pagination="selectorMode === 'add'"
+    :fetch-api="selectorMode === 'add' ? userApi.getUserPage : undefined"
+    :filter-params="filterParams"
+    @confirm="handleConfirm"
+  />
+</template>
+
+<script setup lang="ts">
+import { ref } from 'vue';
+import { UserSelect } from '@/components';
+import { userApi } from '@/apis/system';
+import type { UserVO } from '@/types';
+
+const showSelector = ref(false);
+const selectorMode = ref<'add' | 'remove'>('add');
+const currentUsers = ref<UserVO[]>([]);
+const filterParams = ref({});
+
+function handleConfirm(selectedUsers: UserVO[]) {
+  if (selectorMode.value === 'add') {
+    // 添加用户逻辑
+  } else {
+    // 删除用户逻辑
+  }
+}
+</script>
+```
+
+## API 方法要求
+
+使用 `usePagination` 时，`fetchApi` 方法需要符合以下签名：
+
+```typescript
+async function fetchApi(
+  pageParam: PageParam, 
+  filter?: any
+): Promise<ResultDomain<UserVO>>
+```
+
+### PageParam 类型
+
+```typescript
+interface PageParam {
+  page: number;  // 当前页码（从1开始）
+  size: number;  // 每页数量
+}
+```
+
+### ResultDomain 类型
+
+```typescript
+interface ResultDomain<T> {
+  success: boolean;
+  message?: string;
+  dataList?: T[];
+  pageParam?: {
+    totalElements: number;  // 总记录数
+    // ... 其他分页信息
+  };
+}
+```
+
+## 特性说明
+
+### 滚动分页加载
+
+- 当启用 `usePagination` 时，左侧面板支持滚动加载更多数据
+- 滚动到距离底部 50px 时自动加载下一页
+- 显示加载状态和"已加载全部数据"提示
+- 搜索时自动重置分页并重新加载
+
+### 搜索功能
+
+- **分页模式**：搜索关键词会传递给 API，在服务端进行过滤
+- **静态模式**：搜索在前端进行过滤
+
+### 数据过滤
+
+组件会自动过滤掉右侧已选择的用户，避免重复选择。
+
+## 性能优化建议
+
+1. **数据量 < 100**：使用静态数据模式
+2. **数据量 > 100**：使用分页加载模式
+3. **数据量 > 1000**：使用分页加载 + 服务端搜索
+
+## 注意事项
+
+1. 使用分页模式时，`availableUsers` 会被忽略
+2. 删除模式下通常使用静态数据（当前已分配的用户）
+3. `filterParams` 支持传入额外的过滤条件，会合并到 API 请求中
