ScrollIntoView() 导致整个页面移动

Question

I am using ScrollIntoView() to scroll the highlighted item in a list into view. When I scroll downwards ScrollIntoView(false) works perfectly. But when I scroll upwards, ScrollIntoView(true) is causing the whole page to move a little which I think is intended. Is there a way to avoid the whole page move when using ScrollIntoView(true)?

Here is the structure of my page -

#listOfDivs {
  position:fixed;
  top:100px;
  width: 300px;
  height: 300px;
  overflow-y: scroll;
}

<div="container">
    <div="content"> 
         <div id="listOfDivs"> 
             <div id="item1"> </div>
             <div id="item2"> </div>
             <div id="itemn"> </div>
         </div>
    </div>
</div>

listOfDivs is coming from ajax call. Using mobile safari.

Fixed it with:

element.scrollIntoView({ behavior: 'smooth', block: 'nearest', inline: 'start' })

see: https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

Answer 2

You could use scrollTop instead of scrollIntoView() :

var target = document.getElementById("target");
target.parentNode.scrollTop = target.offsetTop;

jsFiddle: http://jsfiddle.net/LEqjm/

If there's more than one scrollable element that you want to scroll, you'll need to change the scrollTop of each one individually, based on the offsetTop s of the intervening elements. This should give you the fine-grained control to avoid the problem you're having.

EDIT: offsetTop isn't necessarily relative to the parent element - it's relative to the first positioned ancestor. If the parent element isn't positioned (relative, absolute or fixed), you may need to change the second line to:

target.parentNode.scrollTop = target.offsetTop - target.parentNode.offsetTop;

Answer 3

var el = document.querySelector("yourElement");
window.scroll({top: el.offsetTop, behavior: 'smooth'});

Answer 4

I had this problem too, and spent many hours trying to deal with it. I hope my resolution may still help some people.

My fix ended up being:

• For Chrome: changing .scrollIntoView() to .scrollIntoView({block: 'nearest'}) (thanks to @jfrohn).
• For Firefox: apply overflow: -moz-hidden-unscrollable; on the container element that shifts.
• Not tested in other browsers.

使用scrollIntoViewIfNeeded() ...确保浏览器支持它。

Answer 6

in my context, he would push the sticky toolbar off the screen, or enter next to a fab button with absolute.

using the nearest solved.

const element = this.element.nativeElement;
const table = element.querySelector('.table-container');
table.scrollIntoView({
  behavior: 'smooth', block: 'nearest'
});

Answer 7

I've added a way to display the imporper behavior of the ScrollIntoView - http://jsfiddle.net/LEqjm/258/ [it should be a comment but I don't have enough reputation]

$("ul").click(function() {
    var target = document.getElementById("target");
    if ($('#scrollTop').attr('checked')) {
        target.parentNode.scrollTop = target.offsetTop;    
    } else {
        target.scrollIntoView(!0);
    }
});

jQuery plugin scrollintoview() increases usability

Instead of default DOM implementation you can use a plugin that animates movement and doesn't have any unwanted effects. Here's the simplest way of using it with defaults:

$("yourTargetLiSelector").scrollintoview();

Anyway head over to this blog post where you can read all the details and will eventually get you to GitHub source code of the plugin.

This plugin automatically searches for the closest scrollable ancestor element and scrolls it so that selected element is inside its visible view port. If the element is already in the view port it doesn't do anything of course.

Adding more information to @Jesco post.

• Element.scrollIntoViewIfNeeded() non-standard WebKit method for Chrome, Opera, Safari browsers.
  If the element is already within the visible area of the browser window, then no scrolling takes place .
• Element.scrollIntoView() method scrolls the element on which it's called into the visible area of the browser window.

Try the below code in mozilla.org scrollIntoView() link. ^{Post to identify Browser}

var xpath = '//*[@id="Notes"]';
ScrollToElement(xpath);

function ScrollToElement(xpath) {
    var ele = $x(xpath)[0];
    console.log( ele );

    var isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime);
    if (isChrome) { // Chrome
        ele.scrollIntoViewIfNeeded();
    } else {
        var inlineCenter = { behavior: 'smooth', block: 'center', inline: 'start' };
        ele.scrollIntoView(inlineCenter);
    }
}

Just to add an answer as per my latest experience and working on VueJs. I found below piece of code ad best, which does not impact your application in anyways.

const el = this.$el.getElementsByClassName('your_element_class')[0];
if (el) {
   scrollIntoView(el,
                  {
                       block: 'nearest',
                       inline: 'start',
                       behavior: 'smooth',
                       boundary: document.getElementsByClassName('main_app_class')[0]
                    });
     }

main_app_class is the root class

your_element_class is the element/view where you can to scroll into

And for browser which does not support ScrollIntoView() just use below library its awesome https://www.npmjs.com/package/scroll-into-view-if-needed

Answer 11

Using Brilliant's idea, here's a solution that only (vertically) scrolls if the element is NOT currently visible. The idea is to get the bounding box of the viewport and the element to be displayed in browser-window coordinate space. Check if it's visible and if not, scroll by the required distance so the element is shown at the top or bottom of the viewport.

    function ensure_visible(element_id)
    {
        // adjust these two to match your HTML hierarchy
        var element_to_show  = document.getElementById(element_id);
        var scrolling_parent = element_to_show.parentElement;

        var top = parseInt(scrolling_parent.getBoundingClientRect().top);
        var bot = parseInt(scrolling_parent.getBoundingClientRect().bottom);

        var now_top = parseInt(element_to_show.getBoundingClientRect().top);
        var now_bot = parseInt(element_to_show.getBoundingClientRect().bottom);

        // console.log("Element: "+now_top+";"+(now_bot)+" Viewport:"+top+";"+(bot) );

        var scroll_by = 0;
        if(now_top < top)
            scroll_by = -(top - now_top);
        else if(now_bot > bot)
            scroll_by = now_bot - bot;
        if(scroll_by != 0)
        {
            scrolling_parent.scrollTop += scroll_by; // tr.offsetTop;
        }
    }

我遇到了同样的问题，我通过删除放置在页面页footer的transform:translateY CSS 来修复它。

Answer 13

ScrollIntoView() causes page movement. But the following code works fine for me and move the screen to the top of the element:

window.scroll({
  top: document.getElementById('your-element')?.offsetParent.offsetTop,
  behavior: 'smooth',
  block: 'start',
})

Answer 14

FWIW: I found (in Chrome 95, and Firefox 92 (all Mac)) that using:

.scrollIntoView({ behavior:'smooth', block:'center'});

on a scrollable list of options would scroll the body element a little, so I opted to use:

.scrollIntoView({ behavior:'smooth', block:'nearest'});

and select an option past the one I wanted centered (eg in a scrollable elem with 5 lines/options viewable, I selected the 2nd option past the one I wanted centered, thereby centering the desired element.

Answer 15

I found (in Chrome) I could more reliably scroll my element to the top of my parent div (without moving the page) if I scrolled from the bottom up to my element rather than from the top down to my element. Otherwise while my element would scroll into view, it would sometimes still be lower than desired within the div.

To achieve this, I am scrolling in two steps:

1. myScrollableDiv.scrollTop = myScrollableDiv.scrollHeight which instantly scrolls to the bottom of my scrollable div
2. (as per other answers here) Scroll my the element into view with animation:

myElementWithinTheScrollingDiv.scrollIntoView({
  behavior: 'smooth',
  block: 'nearest',
})
