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。

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);

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)。

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);
}

我们可以在不使用JQuery和其他库的情况下解决这个问题。

为此，我编写了以下代码:

你有相似的结构，>

<div class="parent">
  <div class="child-one">

  </div>
  <div class="child-two">

  </div>
</div>

JS:

scrollToElement() {
  var parentElement = document.querySelector('.parent');
  var childElement = document.querySelector('.child-two');

  parentElement.scrollTop = childElement.offsetTop - parentElement.offsetTop;
}

我们可以很容易地重写这个方法，以参数的形式传递父和子

方法1 -平滑滚动到元素中的元素

var box = document.querySelector('.box'), targetElm = document.querySelector('.boxChild'); // <-- Scroll to here within ".box" document.querySelector('button').addEventListener('click', function(){ scrollToElm( box, targetElm , 600 ); }); ///////////// function scrollToElm(container, elm, duration){ var pos = getRelativePos(elm); scrollTo( container, pos.top , 2); // duration in seconds } function getRelativePos(elm){ var pPos = elm.parentNode.getBoundingClientRect(), // parent pos cPos = elm.getBoundingClientRect(), // target pos pos = {}; pos.top = cPos.top - pPos.top + elm.parentNode.scrollTop, pos.right = cPos.right - pPos.right, pos.bottom = cPos.bottom - pPos.bottom, pos.left = cPos.left - pPos.left; return pos; } function scrollTo(element, to, duration, onDone) { var start = element.scrollTop, change = to - start, startTime = performance.now(), val, now, elapsed, t; function animateScroll(){ now = performance.now(); elapsed = (now - startTime)/1000; t = (elapsed/duration); element.scrollTop = start + change * easeInOutQuad(t); if( t < 1 ) window.requestAnimationFrame(animateScroll); else onDone && onDone(); }; animateScroll(); } function easeInOutQuad(t){ return t<.5 ? 2*t*t : -1+(4-2*t)*t }; .box{ width:80%; border:2px dashed; height:180px; overflow:auto; } .boxChild{ margin:600px 0 300px; width: 40px; height:40px; background:green; } <button>Scroll to element</button> <div class='box'> <div class='boxChild'></div> </div>

方法2 -使用Element.scrollIntoView:

请注意，浏览器支持并不适合这个版本

var targetElm = document.querySelector('.boxChild'), // reference to scroll target button = document.querySelector('button'); // button that triggers the scroll // bind "click" event to a button button.addEventListener('click', function(){ targetElm.scrollIntoView() }) .box { width: 80%; border: 2px dashed; height: 180px; overflow: auto; scroll-behavior: smooth; /* <-- for smooth scroll */ } .boxChild { margin: 600px 0 300px; width: 40px; height: 40px; background: green; } <button>Scroll to element</button> <div class='box'> <div class='boxChild'></div> </div>

方法3 -使用CSS滚动行为:

.box { 宽度:80%; 边框:2px虚线; 身高:180 px; overflow-y:滚动; scroll-behavior:光滑;/* <——*/ ｝ # boxChild { Margin: 600px 0 300px; 宽度:40像素; 高度:40像素; 背景:绿色; ｝ <a href='#boxChild'>滚动到元素</a> < div class =“盒子”> < div id =“boxChild”> < / div > < / div >
