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);

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。

<!-- 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;">

<!-- 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。

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;)

function scrollFullyLeft(id, d, del){

var el = document.getElementById(id);

// Have we not finished scrolling yet?
if(el.scrollLeft < (el.scrollWidth - el.clientWidth)) {
TIMER_SCROLL = setTimeout("scrollFullyLeft('"+id+"',"+d+", "+del+");", del);
}
}
/**

@param del Size of the sleep (ms).*/
function scrollFullyRight(id, d, del){
// Fetch the element.
var el = document.getElementById(id);

el.scrollLeft -= d;
// Have we not finished scrolling yet?
if(el.scrollLeft > 0) {
TIMER_SCROLL = setTimeout("scrollFullyRight('"+id+"',"+d+", "+del+");", del);
}
}
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);
}
另一个使用jQuery和动画的例子。
var container = $('#container');
var element = $('#element');
container.animate({
scrollTop: container.scrollTop = container.scrollTop() + element.offset().top - container.offset().top
}, {
duration: 1000,
specialEasing: {
width: 'linear',
height: 'easeOutBounce'
},
complete: function (e) {
console.log("animation completed");
}
});
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
