Events

Event	Description
section-reached	This event is called every time a section is scrolled into view.

$('body').on('section-reached', function(){ 
console.log('section-reached'); 
})

More

Plugin also gives us access to active section through variable

activeSection

For example we can do this:

$('body').on('section-reached', function(){

var section_title = $('body').sectionScroll.activeSection.data('section-title');
alert(section_title);

})

Let's suppose we have

<section class="scrollable-section" data-short-description="We love coding"></section>

Now we can get short description and print that in our imaginary div

$('body').on('section-reached', function(){

var short_description = $('.body').sectionScroll.activeSection.data('short-description');
$('div').html(short_description);
$('body').sectionScroll.activeSection.css('background-color', '#000'); // Let's change background color of active section

})
