原生JS，跨浏览器，平滑滚动(更新2020)

设置ScrollTop确实可以得到想要的结果，但是滚动非常突然。使用jquery来平滑滚动不是一个选择。因此，这里有一种支持所有主流浏览器的本机方式来完成工作。参比犬

// get the "Div" inside which you wish to scroll (i.e. the container element)
const El = document.getElementById('xyz');

// Lets say you wish to scroll by 100px, 
El.scrollTo({top: 100, behavior: 'smooth'});

// If you wish to scroll until the end of the container
El.scrollTo({top: El.scrollHeight, behavior: 'smooth'});

就是这样!

And here's a working snippet for the doubtful - document.getElementById('btn').addEventListener('click', e => { e.preventDefault(); // smooth scroll document.getElementById('container').scrollTo({top: 175, behavior: 'smooth'}); }); /* just some styling for you to ignore */ .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; } <!-- Dummy html to be ignored --> <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">goose</button>

更新:正如你在评论中看到的，IE11似乎不支持Element.scrollTo()。所以如果你不关心IE11(你真的不应该，微软将在2022年6月退休IE11)，请在你所有的项目中使用它。注意，支持Edge!所以你并没有真正离开你的Edge/Windows用户;)

参考

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

有两个事实:

1) safari不支持scrollIntoView组件。

2) JS框架jQuery可以做这样的工作:

parent = 'some parent div has css position==="fixed"' || 'html, body';

$(parent).animate({scrollTop: $(child).offset().top}, duration)

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);
}

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;
  }
