A jQuery plugin for detecting enter/exit of elements in the viewport when the user scrolls.

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

$('.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);
// });

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)

Please provide pull requests for additional features. Test cases would be most weclome!
