jquery-scrollspy
A jQuery plugin for detecting enter/exit of elements in the viewport when the user scrolls.
New Features
Added a couple new features:
- May 2014 - optional window offset, allows for things like floating navs
- Feb 2014 - supports window resize
- Nov 2013 - throttles scrollspy events so that event handles only fire every 100 milliseconds
Usage
$('.tile').on('scrollSpy:enter', function() {
console.log('enter:', $(this).attr('id'));
});
$('.tile').on('scrollSpy:exit', function() {
console.log('exit:', $(this).attr('id'));
});
$('.tile').scrollSpy();
// or you could do this:
// $.scrollSpy($('.tile'));
// or this
// $('.tile').each(function(i, element) {
// $.scrollSpy(element);
// });
Window Resize
Use the scrollSpy:winSize
event for watching window resize. This fires any time the window is resized by the user.
$.winSizeSpy().on('scrollSpy:winSize', funcy)
