smoothState - wordpress integration scripts

smoothState-wordpress.js

!function( $ ){
"use strict";

// include modified jquery.execReeady.js RIGHT AFTER jquery script, to handle onReady as mod exec
// the approach taken here is this:
// only the absolutely necessary assets (scripts/styles) should be included in ALL pages (e.g jquery, jquery.execReday, smoothState.js, smoothState-wordpress.js)
// all other assets (scripts/styles) per specific page should be included INSIDE the page part handled by smoothState, this script will make sure everything will load and init as transparently as possible
// the smoothState container element is #page and the replaced element is #page > .site.inner which should have a class .page-transition as well
// the transitions are parametrisable through some global settings under window.WPSmoothStateOptions which includes duration, inTransition, outTransition classes
// but one can change that if one wishes, this is quite generic since i use libraries of css-based animations with lots of options, so i find this more generic and parametrisable at will.
// current script adds a .smoothstate.smoothstate-delayed class(es) on container once page loading starts (one can add some ajax loader here, i have one in pure css as well),
// then on page ready it removes the .smoothstate-delayed and adds a .smoothstate-undelayed class (e.g ajax-loader removed), it also adds a .page-exiting and .page-entering on the page that is removrd or added respectively
// finaly when the page transition is over the animation classes are removed as the .smoothstate.smoothstate-undelayed classes of the container
// and any extra scripts of the current page (included INSIDE the loaded page) are waited to load before calling jquery.onReady mod exec
// the above scheme can handle all usual cases (at least) of WP with extra plugins which add their own .js scripts and so on (e.g ajax forms)
