如果你正在使用jQuery，你可以使用以下命令滚动动画:

$(MyContainerDiv).animate({scrollTop: $(MyContainerDiv).scrollTop() + ($('element_within_div').offset().top - $(MyContainerDiv).offset().top)});

动画是可选的:你也可以把上面计算出来的scrollTop值直接放到容器的scrollTop属性中。

假设有一个div元素需要在里面滚动，试试这段代码

document.querySelector (div) .scroll (x, y)

这与我在一个带滚动的div中工作，这应该与你一起工作，以防你将鼠标指向这个元素，然后试图向下或向上滚动。如果它手动工作，它也应该工作

用户动画滚动

下面是一个如何在没有JQuery的情况下以编程方式横向滚动<div>的示例。要垂直滚动，可以将JavaScript对scrollLeft的写入替换为scrollTop。

JSFiddle

HTML

<!-- Left Button. -->
<div style="float:left;">
    <!-- (1) Whilst it's pressed, increment the scroll. When we release, clear the timer to stop recursive scroll calls. -->
    <input type="button" value="«" style="height: 100px;" onmousedown="scroll('scroller',3, 10);" onmouseup="clearTimeout(TIMER_SCROLL);"/>
</div>
<!-- Contents to scroll. -->
<div id="scroller" style="float: left; width: 100px; height: 100px; overflow: hidden;">
    <!-- <3 -->
    <img src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.png?v=9c558ec15d8a" alt="image large" style="height: 100px" />
</div>
<!-- Right Button. -->
<div style="float:left;">
    <!-- As (1). (Use a negative value of 'd' to decrease the scroll.) -->
    <input type="button" value="»" style="height: 100px;" onmousedown="scroll('scroller',-3, 10);" onmouseup="clearTimeout(TIMER_SCROLL);"/>
</div>

JavaScript

// Declare the Shared Timer.
var TIMER_SCROLL;
/** 
Scroll function. 
@param id  Unique id of element to scroll.
@param d   Amount of pixels to scroll per sleep.
@param del Size of the sleep (ms).*/
function scroll(id, d, del){
    // Scroll the element.
    document.getElementById(id).scrollLeft += d;
    // Perform a delay before recursing this function again.
    TIMER_SCROLL = setTimeout("scroll('"+id+"',"+d+", "+del+");", del);
 }

这要归功于Dux。

自动动画滚动

此外，这里还有用于将<div>完全向左和向右滚动的函数。这里我们唯一改变的是，在再次递归调用滚动之前，检查是否已经使用了滚动的完整扩展。

我需要滚动页面上的动态加载元素，所以我的解决方案有点复杂。

这将适用于静态元素，这些静态元素不是惰性加载数据，也不是动态加载数据。

const smoothScrollElement = async (selector: string, scrollBy = 12, prevCurrPos = 0) => {
    const wait = (timeout: number) => new Promise(resolve => setTimeout(resolve, timeout));
    const el = document.querySelector(selector) as HTMLElement;
    let positionToScrollTo = el.scrollHeight;
    let currentPosition = Math.floor(el.scrollTop) || 0;
    let pageYOffset = (el.clientHeight + currentPosition);
    if (positionToScrollTo == pageYOffset) {
        await wait(1000);
    }
    if ((prevCurrPos > 0 && currentPosition <= prevCurrPos) !== true) {
        setTimeout(async () => {
            el.scrollBy(0, scrollBy);
            await smoothScrollElement(selector, scrollBy, currentPosition);
        }, scrollBy);
    }
};

您必须找到要滚动到的DIV中元素的位置，并设置scrollTop属性。

divElem.scrollTop = 0;

更新:

向上或向下移动的示例代码

  function move_up() {
    document.getElementById('divElem').scrollTop += 10;
  }

  function move_down() {
    document.getElementById('divElem').scrollTop -= 10;
  }

浏览器会自动滚动到一个获得焦点的元素，所以你也可以做它来包装你需要滚动到的元素<a>…</a>然后当你需要滚动时将焦点设置在a上
