scrollintoview animation

scrollintoview offset
jquery scrollintoview
scrollintoview alternative
scrollintoview not working
react scrollintoview
scrollintoview smooth not working
angular scrollintoview
scrollintoview callback

My code is at http://jsfiddle.net/mannagod/QT3v5/7/.

The JS is:

function delay() {
    var INTENDED_MONTH = 7 //August
    // INTENDED_MONTH is zero-relative
    now = new Date().getDate(),
rows = document.getElementById('scripture').rows;
    if (new Date().getMonth() != INTENDED_MONTH) {
        // need a value here less than 1, 
        // or the box for the first of the month will be in Red
        now = 0.5
    };
    for (var i = 0, rl = rows.length; i < rl; i++) {
        var cells = rows[i].childNodes;
        for (j = 0, cl = cells.length; j < cl; j++) {
            if (cells[j].nodeName == 'TD'
  && cells[j].firstChild.nodeValue != ''
  && cells[j].firstChild.nodeValue == now) {
                // 'ffff99' // '#ffd700' // TODAY - red
                rows[i].style.backgroundColor = 'red' 
                rows[i].scrollIntoView();
            }
        }
    }
}

I need to find a way to smooth the .scrollintoview(). Right now it 'jumps' to the highlighted row. I need it to smoothly transition to that row. It needs to be done dynamically in replacement of scrollintoview. Any ideas? Thanks.


In most modern browsers (Chrome and Firefox, but not Safari, UC, or IE) you can pass options in an object to .scrollIntoView().

Try this:

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

Other values are behavior: 'instant' or block: 'start' or block: 'end'. See https://developer.mozilla.org/en/docs/Web/API/Element/scrollIntoView

Element.scrollIntoView(), Defines the transition animation. One of auto or smooth . Defaults to auto . block Optional: Defines vertical alignment. The Element interface's scrollIntoView () method scrolls the element's parent container such that the element on which scrollIntoView () is called is visible to the user.


I was searching this issue too and found this solution:

$('html, body').animate({
    scrollTop: $("#elementId").offset().top
}, 1000);

resource: http://www.abeautifulsite.net/smoothly-scroll-to-an-element-without-a-jquery-plugin-2/

Smooth Scrolling, scrollIntoView({ behavior: 'smooth' });. Dustan Kasten has a polyfill for this. And you'd probably only reach for this if you were doing something  and ScrollIntoView does not animate the scrolling. To get animation to happen, you would instead use the ChangeView method of the ScrollViewer part of the UWP ListView. For Example:


Maybe you don't want to add jQuery just for implementing this feature. elem is the element to be scrolled. The destination pos can be taken from the offsetTop property of the element to be moved into view.

function Scroll_To(elem, pos)
{
    var y = elem.scrollTop;
    y += (pos - y) * 0.3;
    if (Math.abs(y-pos) < 2)
    {
        elem.scrollTop = pos;
        return;
    }
    elem.scrollTop = y;
    setTimeout(Scroll_To, 40, elem, pos);   
}

scrollIntoView is the best thing since sliced bread - DEV, Making elements scroll into view used to be hard, especially with animation. Now it's super easy with Tagged with html, javascript, webdev,  It returns a promise that resolves when the animation is done; It accepts an element as coordinate and scrolls to it (also works with a selector like #some-section-id) It will not overwrite any existing public structure (like the scrollTo native function or Math's prototype) Has a default duration


Smooth scrolling using requestAnimationFrame over a specific duration with no jQuery.

Demo: http://codepen.io/Shadeness/pen/XXyvKG?editors=0010

window.bringIntoView_started = 0;
window.bringIntoView_ends = 0;
window.bringIntoView_y = 0;
window.bringIntoView_tick = function() {
  var distanceLeft, dt, duration, t, travel;
  t = Date.now();
  if (t < window.bringIntoView_ends) {
    dt = t - window.bringIntoView_started;
    duration = window.bringIntoView_ends - window.bringIntoView_started;
    distanceLeft = window.bringIntoView_y - document.body.scrollTop;
      travel = distanceLeft * (dt / duration);
      document.body.scrollTop += travel;
      window.requestAnimationFrame(window.bringIntoView_tick);
  } else {
    document.body.scrollTop = window.bringIntoView_y;
  }
};
window.bringIntoView = function(e, duration) {
  window.bringIntoView_started = Date.now();
  window.bringIntoView_ends = window.bringIntoView_started + duration;
  window.bringIntoView_y = Math.min(document.body.scrollTop + e.getBoundingClientRect().top, document.body.scrollHeight - window.innerHeight);
  window.requestAnimationFrame(window.bringIntoView_tick);
};

Eg:

bringIntoView(document.querySelector('#bottom'), 400)

It should speed up as dt (deltaTime) gets bigger, and slows down as distanceLeft get's smaller. I considered breaking the loop if the user scrolled but meh. Global variables prevent the previous call from completely taking over, but doesn't cancel the previous recursive loop so it'll animate twice as fast.
