使用jQuery动画:

$('#DebugContainer').stop().animate({
  scrollTop: $('#DebugContainer')[0].scrollHeight
}, 800);

Css只有:

.scroll-container {
  overflow-anchor: none;
}

使滚动条在添加子元素时不会停留在顶部。例如，当聊天底部添加新消息时，滚动聊天到新消息。

以下是我在我的网站上使用的:

var objDiv = document.getElementById("your_div");
objDiv.scrollTop = objDiv.scrollHeight;

我使用了第一个项目div的Y坐标和所选项目div的Y坐标之间的差异。下面是JavaScript/JQuery代码和html:

function scrollTo(event){ // In my proof of concept, I had a few <button>s with value // attributes containing strings with id selector expressions // like "#item1". let selectItem = $($(event.target).attr('value')); let selectedDivTop = selectItem.offset().top; let scrollingDiv = selectItem.parent(); let firstItem = scrollingDiv.children('div').first(); let firstItemTop = firstItem.offset().top; let newScrollValue = selectedDivTop - firstItemTop; scrollingDiv.scrollTop(newScrollValue); } <div id="scrolling" style="height: 2rem; overflow-y: scroll"> <div id="item1">One</div> <div id="item2">Two</div> <div id="item3">Three</div> <div id="item4">Four</div> <div id="item5">Five</div> </div>

您可以使用Element.scrollTo()方法。

它可以使用内置的浏览器/操作系统动画，所以它非常流畅。

function scrollToBottom() { const scrollContainer = document.getElementById('container'); scrollContainer.scrollTo({ top: scrollContainer.scrollHeight, left: 0, behavior: 'smooth' }); } // initialize dummy content const scrollContainer = document.getElementById('container'); const numCards = 100; let contentInnerHtml = ''; for (let i=0; i<numCards; i++) { contentInnerHtml += `<div class="card mb-2"><div class="card-body">Card ${i + 1}</div></div>`; } scrollContainer.innerHTML = contentInnerHtml; .overflow-y-scroll { overflow-y: scroll; } <link href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" rel="stylesheet"/> <div class="d-flex flex-column vh-100"> <div id="container" class="overflow-y-scroll flex-grow-1"></div> <div> <button class="btn btn-primary" onclick="scrollToBottom()">Scroll to bottom</button> </div> </div>

如果你使用jQuery scrollTop，这就简单多了:

$("#mydiv").scrollTop($("#mydiv")[0].scrollHeight);
