Scroll to element on page using the elements id, Meteor


Scroll to element on page using the elements id, Meteor

it should still fix some issue Not sure if I understand you right but you can add hashtags in meteor too. Just route with iron-route r to a new hashtag by clicking your href.
code :
<li><a href="{{pathFor 'posts.index'}}"><span class='glyphicon glyphicon-home'></span> Blog</a></li>
<li><a href="{{pathFor 'overview' hash='about'}}"><span class='glyphicon glyphicon-user'></span> About Me</a></li>
<li><a href="{{pathFor 'overview' hash='meetup'}}"><span class='glyphicon glyphicon-map-marker'></span>My Meetup</a></li>
<li><a href="{{pathFor 'overview' hash='contact'}}"><span class='glyphicon glyphicon-envelope'></span> Contact Me</a></li>
Router._scrollToHash = function(hash) {
  var section = $(hash);
  if (section.length) {
    var sectionTop = section.offset().top;
    $("html, body").animate({
      scrollTop: sectionTop
    }, "slow");
  }
};

I wish this helpful for you Ok, I think I figured it out.
JS Fiddle: http://jsfiddle.net/picitelli/Tfbb3/
code :
function scrollTo(el) {

  $('html,body').animate({
    scrollTop: $(el).offset().top
  }, 500);

}

var scroller = $('.scroller'),
    scrollPrev = scroller.find('.prev'),
    scrollNext = scroller.find('.next'),
    section = $('.section'),
    position = -1;

// add data count to each section
section.each(function(index) {

    $(this).attr('data-count', index);

});

// next click through scrolling
scrollNext.on('click', function() {

    if (position < section.length - 1) {

      position++;

      scrollTo(section[position]);

    }

});

// prev click through scrolling
scrollPrev.on('click', function() {

    if (position > 0) {

      position--;

      scrollTo(section[position]);

    }

});

// page scroll position detection
$(window).scroll(function() {

    var currentPosition = $(this).scrollTop();

    section.each(function() {

        var top = $(this).offset().top,
            bottom = top + $(this).height();

        if(currentPosition >= top && currentPosition <= bottom) {

            var sectionCount = $(this).attr('data-count');

            position = sectionCount;

        }

     });

});

hop of those help? I am at a bit of a loss for how how to do this.
code :
    var thresholdY = 150; 
    var thresholdCounter = 0; 
    var speed = 4; 
    var element = document.getElementById('yourElement'); 

    window.onscroll = function(event) { 
      if(scrollY > thresholdY) { 
        window.scrollTo(0, thresholdY); 
        element.setAttribute('style', 'transform:translate3d(0,' + (--thresholdCounter * speed) + 'px,0);'); 
        return false; 
      }
      return null; 
    };

wish of those help Depending on your specific needs you can organise the code in such way, so that you can pass the id of the element that needs to be scrolled to the click handler.
code :
<a href="#scrollHere">Click me</a>

<div id="scrollHere"></div>

$('a[href^="#"]').on('click', function(event) {
    var target = $(this.href);
    if( target.length ) {
        event.preventDefault();
        $('html, body').animate({
            scrollTop: target.offset().top
        }, 1000);
    }
});
$('.someElement').on('click', function(event) {
        var target = $('#someElementToScrollTo');    
        $('html, body').animate({
            scrollTop: target.offset().top
        }, 1000);    
});

it should still fix some issue I have chat app, and if you use Slack you know that when you enter to the room, you will automatically find yourself at the bottom of your chat room. So I decided to do this and what I have , This is one very frustrating aspect of Blaze. Try this, though:
code :
Template.room.onRendered(function () {
  var template = this;

  this.autorun(function () {
    if (template.subscriptionsReady()) {
      Tracker.afterFlush(function () {
        $('html, body').scrollTop($(document).height() - $(window).height());
      });
    }
  });
});
How to apply to many elements: JavaScript scroll effect on element only when parent element is in viewport

How to apply to many elements: JavaScript scroll effect on element only when parent element is in viewport

I wish this helpful for you Use the IntersectionObserver API to observer if elements are in view, or not. This api monitors elements that you specify and triggers a callback whenever an observed element enters or leaves the viewport. This way you can create a list of elements that are in the viewport.
To help with that create a Set. Sets take any kind of type of value and stores it in a list, like a supercharged array, but only with unique values. So no element will be in there twice.
code :
const inViewSections = new Set();
const offsetMap = new Map();
const targetMap = new Map();

function calculateOffsetsOfSections(sections, map) {
  const bodyTop = document.body.getBoundingClientRect().top;
  sections.forEach(function(section) {
    const sectionTop = section.getBoundingClientRect().top;
    const offset = sectionTop - bodyTop;
    map.set(section, offset);
  });
}

function mapTargetsOfSections(sections, map) {
  sections.forEach(function(section) {
    const target = section.querySelector('.scroll');
    if (target !== null) {
      map.set(section, target);
    }
  });
}

function observeSections(sections, observer) {
  sections.forEach(function(section) {
    observer.observe(section);
  });
}

function intersectionCallback(entries) {
  entries.forEach(function(entry) {
    if (entry.isIntersecting === true) {
      inViewSections.add(entry.target);
    } else {
      inViewSections.delete(entry.target);
    }
  });
}

const observer = new IntersectionObserver(intersectionCallback, {
  root: null,
  rootMargin: '0px',
  threshold: [0]
});

let sections = document.querySelectorAll('.section');
calculateOffsetsOfSections(sections, offsetMap);
mapTargetsOfSections(sections, targetMap);
observeSections(sections, observer);

window.addEventListener('resize', function(e) {
  calculateOffsetsOfSections(sections, offsetMap);
});

window.addEventListener('scroll', function(e) {
  inViewSections.forEach(function(section) {
    if (offsetMap.has(section) && targetMap.has(section)) {
      const target = targetMap.get(section);
      const offset = offsetMap.get(section);
      var rate = Math.round((window.pageYOffset - offset) * -0.5);
      target.style.transform = 'translate3d(0px, ' + rate + 'px, 0px)';
    }
  });
}, {passive: true});
