我有一个滚动的div,我想有一个事件,当我点击它,它将迫使这个div滚动查看里面的一个元素。 我这样写它的JavasSript:

document.getElementById(chr).scrollIntoView(true);

但这在滚动div本身的同时滚动整个页面。 如何解决这个问题?

我想这样说: MyContainerDiv.getElementById(杆).scrollIntoView(真正的);


当前回答

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

其他回答

其他答案都不能解决我的问题。

我摆弄了scrollIntoView参数,并设法找到了一个解决方案。将inline设置为开始并将block设置为最近的位置,以防止父元素(或整个页面)滚动:

document.getElementById(chr).scrollIntoView({
   behavior: 'smooth',
   block: 'nearest',
   inline: 'start'
});

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。

JavaScript

// Declare the Shared Timer.
var TIMER_SCROLL;
/** 
Scroll fully left function; completely scrolls  a <div> to the left, as far as it will go.
@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 scrollFullyLeft(id, d, del){
    // Fetch the element.
    var el = document.getElementById(id);
    // Scroll the element.
    el.scrollLeft += d;
    // Have we not finished scrolling yet?
    if(el.scrollLeft < (el.scrollWidth - el.clientWidth)) {
        TIMER_SCROLL = setTimeout("scrollFullyLeft('"+id+"',"+d+", "+del+");", del);
    }
}

/** 
Scroll fully right function; completely scrolls  a <div> to the right, as far as it will go.
@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 scrollFullyRight(id, d, del){
    // Fetch the element.
    var el = document.getElementById(id);
    // Scroll the element.
    el.scrollLeft -= d;
    // Have we not finished scrolling yet?
    if(el.scrollLeft > 0) {
        TIMER_SCROLL = setTimeout("scrollFullyRight('"+id+"',"+d+", "+del+");", del);
    }
}

代码应该是:

var divElem = document.getElementById('scrolling_div');
var chElem = document.getElementById('element_within_div');
var topPos = divElem.offsetTop;
divElem.scrollTop = topPos - chElem.offsetTop;

您希望滚动子顶部位置和div顶部位置之间的差值。

使用以下方法访问子元素:

var divElem = document.getElementById('scrolling_div'); 
var numChildren = divElem.childNodes.length;

等等....

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

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>
