|
||
* ⚡ 【核心逻辑】注册 Socket 新事件回调 - 当收到新事件时智能刷新列表
|
||
*
|
||
* 工作流程:
|
||
* 1. Socket 收到 'new_event' 事件 → NotificationContext 触发所有注册的回调
|
||
* 2. 本回调被触发 → 检查当前路由是否为 /community
|
||
* 3. 如果在 /community 页面 → 调用 DynamicNewsCard.refresh() 方法
|
||
* 4. DynamicNewsCard 根据模式和滚动位置决定是否刷新:
|
||
* - 纵向模式 + 第1页 → 刷新列表
|
||
* - 纵向模式 + 其他页 → 不刷新(避免打断用户)
|
||
* - 平铺模式 + 滚动在顶部 → 刷新列表
|
||
* - 平铺模式 + 滚动不在顶部 → 仅显示 Toast 提示
|
||
*
|
||
* 设计要点:
|
||
* - 使用 registerEventUpdateCallback 注册回调,返回的函数用于清理
|
||
* - 路由检查:只在 /community 页面触发刷新
|
||
* - 智能刷新:由 DynamicNewsCard 根据上下文决定刷新策略
|
||
* - 自动清理:组件卸载时自动注销回调
