這篇文章主要介紹了vue窗口內(nèi)容滾動到底部實現(xiàn)過程,以上為個人經(jīng)驗,希望能給大家一個參考,也希望大家多多支持腳本之家,

vue窗口內(nèi)容滾動到底部

onMounted(() => {
  scrollToBottom()
})
// 滾動到底部方法
const scrollToBottom = () => {
  // 獲取聊天窗口容器
  let chatRoom: any = document.querySelector(".chat-content");
  // 滾動到容器底部
  chatRoom.scrollTop = chatRoom.scrollHeight;
}

效果

聊天窗口代碼
