ScrollSpy is a small but power
ScrollSpy
ScrollSpy is a small but powerful MooTools plugin that allows you to listen to scrolling within any DOM element and execute functions based upon the element's scroll position.
ScrollSpy can be initialized at any time but is generally initialized at the top of the document during the page's normal load. There are no required arguments -- only options.
#JS
/* my "Go To Top" link element */
var link = document.id('gototop');
/* scrollspy instance */
var ss = new ScrollSpy({
min: 300,
onEnter: function() {
link.fade('in'); //show the "Go To Top" link
},
onLeave: function() {
link.fade('out'); //hide the "Go To Top" link
}
});
