jQuery Roundup: 1.5.2, Waypoints, Sausage
jQuery 1.5.2 Released
jQuery 1.5.2 was released on March 31st, just as planned. Who says IT projects are late and over-budget?! This release includes 18 bug fixes.
jQuery Waypoints
jQuery Waypoints (GitHub: imakewebthings / jquery-waypoints, MIT/GPL) by Caleb Troughton triggers a function when scrolling reaches an element. This could be used to create infinite scrolling, sticky elements, and even scrolling analytics).
Waypoints works by applying a callback to an element:
$('.entry').waypoint(function() {
alert('You have scrolled to an entry.');
});
Sausage
Sausage (GitHub: christophercliff / sausage) by Christopher Cliff is a jQuery UI widget for presenting context alongside infinite scrolling pages. There’s a nice example of Sausage showing CouchDB documentation, with section annotations along the right-hand-side.
That example uses this JavaScript:
$(window)
.sausage({
content: function (i, $page) {
return '<span class="sausage-span">'
+ $page.find('.anchor').first().text()
+ '</span>';
}
});
Each section of text in the CouchDB documentation is wrapped with an element with a class of page, so the $page part would really look like this: $('.page').find('.anchor').first().text(). That lets Sausage find the title of each section to use for its navigation.
