+/**
+@example
+1. 页面引入该hooks, 并调用useAutoScroll()，返回三个值：canAutoScroll, contentRef, contentScrollFN
+import { useAutoScroll } from '@/hooks/useAutoScroll';
+const { canAutoScroll, contentRef, contentScrollFN } = useAutoScroll();
+  
+2. 需要配置自动滚动的dom加上contentRef属性(contentRef名称不能修改，必须匹配)，并监听scroll调用contentScrollFN()方法
+<div
+    class="wordbox"
+    ref="contentRef"
+    @scroll="contentScrollFN"
+>
+</div>
+
+3. 在请求流式数据时，设置canAutoScroll为true
+
+### 注意事项
