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

你需要获得你想要滚动到视图中的元素的顶部偏移量，相对于它的父元素(滚动div容器):

var myElement = document.getElementById('element_within_div');
var topPos = myElement.offsetTop;

变量topPos现在被设置为滚动div的顶部与您希望可见的元素之间的距离(以像素为单位)。

现在我们使用scrollTop命令让div滚动到那个位置:

document.getElementById('scrolling_div').scrollTop = topPos;

如果你正在使用原型JS框架，你会做同样的事情:

var posArray = $('element_within_div').positionedOffset();
$('scrolling_div').scrollTop = posArray[1];

同样，这将滚动div，以便您希望看到的元素恰好位于顶部(如果不可能，则尽可能向下滚动，使其可见)。

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;
  }

只有在需要的时候，你才能使用scrollIfNeeded函数将一个元素滚动到div的视图中:

function scrollIfNeeded(element, container) { if (element.offsetTop < container.scrollTop) { container.scrollTop = element.offsetTop; } else { const offsetBottom = element.offsetTop + element.offsetHeight; const scrollBottom = container.scrollTop + container.offsetHeight; if (offsetBottom > scrollBottom) { container.scrollTop = offsetBottom - container.offsetHeight; } } } document.getElementById('btn').addEventListener('click', ev => { ev.preventDefault(); scrollIfNeeded(document.getElementById('goose'), document.getElementById('container')); }); .scrollContainer { overflow-y: auto; max-height: 100px; position: relative; border: 1px solid red; width: 120px; } body { padding: 10px; } .box { margin: 5px; background-color: yellow; height: 25px; display: flex; align-items: center; justify-content: center; } #goose { background-color: lime; } <div id="container" class="scrollContainer"> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div id="goose" class="box">goose</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> <div class="box">duck</div> </div> <button id="btn">scroll to goose</button>

这是一个简单的纯JavaScript解决方案，适用于目标数字(值为scrollTop)，目标DOM元素，或一些特殊的字符串情况:

/**
 * target - target to scroll to (DOM element, scrollTop Number, 'top', or 'bottom'
 * containerEl - DOM element for the container with scrollbars
 */
var scrollToTarget = function(target, containerEl) {
    // Moved up here for readability:
    var isElement = target && target.nodeType === 1,
        isNumber = Object.prototype.toString.call(target) === '[object Number]';

    if (isElement) {
        containerEl.scrollTop = target.offsetTop;
    } else if (isNumber) {
        containerEl.scrollTop = target;
    } else if (target === 'bottom') {
        containerEl.scrollTop = containerEl.scrollHeight - containerEl.offsetHeight;
    } else if (target === 'top') {
        containerEl.scrollTop = 0;
    }
};

下面是一些用法的例子:

// Scroll to the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget('top', scrollableDiv);

or

// Scroll to 200px from the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget(200, scrollableDiv);

or

// Scroll to targetElement
var scrollableDiv = document.getElementById('scrollable_div');
var targetElement= document.getElementById('target_element');
scrollToTarget(targetElement, scrollableDiv);

这就是我最终得到的

/** Set parent scroll to show element
 * @param element {object} The HTML object to show
 * @param parent {object} The HTML object where the element is shown  */
var scrollToView = function(element, parent) {
    //Algorithm: Accumulate the height of the previous elements and add half the height of the parent
    var offsetAccumulator = 0;
    parent = $(parent);
    parent.children().each(function() {
        if(this == element) {
            return false; //brake each loop
        }
        offsetAccumulator += $(this).innerHeight();
    });
    parent.scrollTop(offsetAccumulator - parent.innerHeight()/2);
}
