How to make full-page vertical slides that roll with the mouse scroll?

Question

It is possible to make the page scroll to a specific element (such as <section> or <div>)? It’s like a vertical slide (Section) that occupies the entire screen.

As an example, this site I think you use fullpage mousewheel: https://mega.co.nz

Answer 1

I hitched a ride in this reply from Sozão, who already had the code ready.

The example is in jQuery, but can do a good with pure Javascript (by the way, it is recommended, unless your site is already all based on jQuery).

The important thing is to understand two concepts:

1. on('mousewheel DOMMouseScroll')

   The mousewheel is triggered when the mouse wheel is triggered; the DOMMouseScroll is the equivalent of Firefox for this.

2. event.preventDefault();

   As you will manage the event from the mouse wheel, it is critical that you warn the browser that it is not to use the normal action for that event. That’s where the preventDefault.

Demonstration

Click on "Run code snippet" just below the following block, click on frame and test with mouse wheel.

(function() {
  var delay = false;

  $(document).on('mousewheel DOMMouseScroll', function(event) {
    event.preventDefault();
    if(delay) return;

    delay = true;
    setTimeout(function(){delay = false},200)

    var wd = event.originalEvent.wheelDelta || -event.originalEvent.detail;

    var a= document.getElementsByTagName('a');
    if(wd < 0) {
      for(var i = 0 ; i < a.length ; i++) {
        var t = a[i].getClientRects()[0].top;
        if(t >= 40) break;
      }
    }
    else {
      for(var i = a.length-1 ; i >= 0 ; i--) {
        var t = a[i].getClientRects()[0].top;
        if(t < -20) break;
      }
    }
    $('html,body').animate({
      scrollTop: a[i].offsetTop
    });
  });
})();

body, html { width:100%; height:100%; margin:0; padding:0 }
a { display:block; color:red; margin-bottom:1em; }
.page {width:100%;height:100%;margin:0 auto;padding:0 15%;box-sizing:border-box;background:#fee}
.page:nth-child(odd) {background:#efe}

As an alternative there is already a jQuery plugin ready for this, is the:

• https://github.com/alvarotrigo/fullPage.js

• Go to to to download: https://github.com/alvarotrigo/fullPage.js/archive/master.zip

It works like this, by <section> or <div> and also supports back and forth from the browser:

Supports: - IE8+ - Opera - Chrome - Firefox

To use it is necessary to add this to the header:

<link rel="stylesheet" type="text/css" href="jquery.fullPage.css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="vendors/jquery.easings.min.js"></script>
<script type="text/javascript" src="vendors/jquery.slimscroll.min.js"></script>
<script type="text/javascript" src="jquery.fullPage.js"></script>

(if you have already added jquery to your website then remove the second line of code above)

The html should look like this:

<div id="fullpage">
    <div class="section">Some section</div>
    <div class="section">Some section</div>
    <div class="section">Some section</div>
    <div class="section">Some section</div>
</div>

To boot you must add this to your main js:

$(document).ready(function() {
    $('#fullpage').fullpage();
});

A more complex and eventful example:

$(document).ready(function() {
    $('#fullpage').fullpage({
        //Navigation
        menu: '#menu',
        lockAnchors: false,
        anchors:['firstPage', 'secondPage'],
        navigation: false,
        navigationPosition: 'right',
        navigationTooltips: ['firstSlide', 'secondSlide'],
        showActiveTooltip: false,
        slidesNavigation: true,
        slidesNavPosition: 'bottom',

        //Scrolling
        css3: true,
        scrollingSpeed: 700,
        autoScrolling: true,
        fitToSection: true,
        fitToSectionDelay: 1000,
        scrollBar: false,
        easing: 'easeInOutCubic',
        easingcss3: 'ease',
        loopBottom: false,
        loopTop: false,
        loopHorizontal: true,
        continuousVertical: false,
        normalScrollElements: '#element1, .element2',
        scrollOverflow: false,
        touchSensitivity: 15,
        normalScrollElementTouchThreshold: 5,

        //Accessibility
        keyboardScrolling: true,
        animateAnchor: true,
        recordHistory: true,

        //Design
        controlArrows: true,
        verticalCentered: true,
        resize : false,
        sectionsColor : ['#ccc', '#fff'],
        paddingTop: '3em',
        paddingBottom: '10px',
        fixedElements: '#header, .footer',
        responsiveWidth: 0,
        responsiveHeight: 0,

        //Custom selectors
        sectionSelector: '.section',
        slideSelector: '.slide',

        //events
        onLeave: function(index, nextIndex, direction){},
        afterLoad: function(anchorLink, index){},
        afterRender: function(){},
        afterResize: function(){},
        afterSlideLoad: function(anchorLink, index, slideAnchor, slideIndex){},
        onSlideLeave: function(anchorLink, index, slideIndex, direction, nextSlideIndex){}
    });
});

And it also supports Lazy-load, so change the attribute src for data-src:

<img data-src="image.png">
<video>
    <source data-src="video.webm" type="video/webm" />
    <source data-src="video.mp4" type="video/mp4" />
</video>

And supports anchors:

<ul id="myMenu">
    <li data-menuanchor="firstPage" class="active"><a href="#firstPage">First section</a></li>
    <li data-menuanchor="secondPage"><a href="#secondPage">Second section</a></li>
    <li data-menuanchor="thirdPage"><a href="#thirdPage">Third section</a></li>
    <li data-menuanchor="fourthPage"><a href="#fourthPage">Fourth section</a></li>
</ul>

$('#fullpage').fullpage({
    anchors: ['firstPage', 'secondPage', 'thirdPage', 'fourthPage', 'lastPage'],
    menu: '#myMenu'
});
