BookBlock is a jQuery plugin that can be used for creating booklet-like components that allow a “page flip” navigation. Any content can be used, such as images or text. The plugin transforms the structure only when needed (i.e. when flipping a page) and uses some overlays as shadow for the pages to create more realism.
We will be using jQuery++ by Bitovi which has some add-ons for jQuery (specifically, to add the swipe event).
The following structure will allow to add custom content in a wrapper with the class “cf-item”, which represents an open page (left and right side):
<div id="bb-bookblock" class="bb-bookblock"> <div class="bb-item"> <!-- custom content --> </div> <div class="bb-item"> </div> <div class="bb-item"> <!-- ... --> </div> <div class="bb-item"> <!-- ... --> </div> <!-- ... --> </div>The plugin can be called like this:
$(function() {
$( '#bb-bookblock' ).bookblock();
});
You also have to include the other scripts that are needed (see one of the demo files).
Options
The following options are available:// speed for the flip transition in ms.
speed : 1000,
// easing for the flip transition.
easing : 'ease-in-out',
// if set to true, both the flipping page and the sides will have an overlay to simulate shadows
shadows : true,
// opacity value for the "shadow" on both sides (when the flipping page is over it).
// value : 0.1 - 1
shadowSides : 0.2,
// opacity value for the "shadow" on the flipping page (while it is flipping).
// value : 0.1 - 1
shadowFlip : 0.1,
// perspective value
perspective : 1300,
// if we should show the first item after reaching the end.
circular : false,
// if we want to specify a selector that triggers the next() function. example: '#bb-nav-next'.
nextEl : '',
// if we want to specify a selector that triggers the prev() function.
prevEl : '',
// callback after the flip transition.
// page is the current item's index.
// isLimit is true if the current page is the last one (or the first one).
onEndFlip : function( page, isLimit ) { return false; },
// callback before the flip transition.
// page is the current item's index.
onBeforeFlip: function( page ) { return false; }
