平滑滚动Javascript:

. getelementbyid(“信息”)。scrollIntoView({behavior: 'smooth'， block: 'end'});

将到可滚动元素顶部的距离设置为元素的总高度。

const element = this.shadowRoot.getElementById('my-scrollable-div')
element.scrollTop = element.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>

为什么不使用简单的CSS来做到这一点呢?

诀窍是使用display: flex;和弯曲方向:列反向;

Here is a working example. https://codepen.io/jimbol/pen/YVJzBg

以下是我在我的网站上使用的:

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

试试下面的代码:

const scrollToBottom = (id) => {
    const element = document.getElementById(id);
    element.scrollTop = element.scrollHeight;
}

你也可以使用Jquery使滚动平滑:

const scrollSmoothlyToBottom = (id) => {
    const element = $(`#${id}`);
    element.animate({
        scrollTop: element.prop("scrollHeight")
    }, 500);
}
