Sep 17 00:00:00 2001 From: Cristiano Cortezia Date: Thu, 16 Jan 2014 14:44:32 -0200 Subject: Fixes bad NaN applied to style on updateParallax. The previous criteria "verticalSlideCount > 0" would result in verticalOffset being NaN when verticalSlideCount == 1. This would cause dom.background.style.backgroundPosition to be set to something like "123px NaNpx", ultimately preventing the parallax effect to play (silently failing so far). --- js/reveal.js | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'js') diff --git a/js/reveal.js b/js/reveal.js index 98d802e..b7764d3 100644 --- a/js/reveal.js +++ b/js/reveal.js @@ -2032,7 +2032,7 @@ var Reveal = (function(){ var slideHeight = dom.background.offsetHeight; var verticalSlideCount = verticalSlides.length; - var verticalOffset = verticalSlideCount > 0 ? -( backgroundHeight - slideHeight ) / ( verticalSlideCount-1 ) * indexv : 0; + var verticalOffset = verticalSlideCount > 1 ? -( backgroundHeight - slideHeight ) / ( verticalSlideCount-1 ) * indexv : 0; dom.background.style.backgroundPosition = horizontalOffset + 'px ' + verticalOffset + 'px'; -- cgit v1.2.3 From 44e6f7ace070401801a50ad6cf47a8dab8d933da Mon Sep 17 00:00:00 2001 From: Armand Abric Date: Fri, 7 Feb 2014 19:03:48 +0100 Subject: Increase Logitech R400 remote compatibity. --- js/reveal.js | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'js') diff --git a/js/reveal.js b/js/reveal.js index 9d389c5..4377400 100644 --- a/js/reveal.js +++ b/js/reveal.js @@ -2773,8 +2773,8 @@ var Reveal = (function(){ case 32: isOverview() ? deactivateOverview() : event.shiftKey ? navigatePrev() : navigateNext(); break; // return case 13: isOverview() ? deactivateOverview() : triggered = false; break; - // b, period, Logitech presenter tools "black screen" button - case 66: case 190: case 191: togglePause(); break; + // two-spot, semicolon, b, period, Logitech presenter tools "black screen" button + case 58: case: 59: case 66: case 190: case 191: togglePause(); break; // f case 70: enterFullscreen(); break; // a -- cgit v1.2.3 From 2aef97584a2c459d425d3ade55633120972c1ca7 Mon Sep 17 00:00:00 2001 From: Hakim El Hattab Date: Sun, 16 Feb 2014 17:12:05 +0100 Subject: update (c) year --- js/reveal.js | 2 +- js/reveal.min.js | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) (limited to 'js') diff --git a/js/reveal.js b/js/reveal.js index 9d389c5..66c975e 100644 --- a/js/reveal.js +++ b/js/reveal.js @@ -3,7 +3,7 @@ * http://lab.hakim.se/reveal-js * MIT licensed * - * Copyright (C) 2013 Hakim El Hattab, http://hakim.se + * Copyright (C) 2014 Hakim El Hattab, http://hakim.se */ var Reveal = (function(){ diff --git a/js/reveal.min.js b/js/reveal.min.js index fb050d1..8d9a64d 100644 --- a/js/reveal.min.js +++ b/js/reveal.min.js @@ -1,9 +1,9 @@ /*! - * reveal.js 2.6.1 (2013-12-21, 18:11) + * reveal.js 2.6.1 (2014-02-16, 17:11) * http://lab.hakim.se/reveal-js * MIT licensed * - * Copyright (C) 2013 Hakim El Hattab, http://hakim.se + * Copyright (C) 2014 Hakim El Hattab, http://hakim.se */ var Reveal=function(){"use strict";function a(a){if(b(),!gc.transforms2d&&!gc.transforms3d)return document.body.setAttribute("class","no-transforms"),void 0;window.addEventListener("load",A,!1);var d=Reveal.getQueryHash();"undefined"!=typeof d.dependencies&&delete d.dependencies,k(bc,a),k(bc,d),r(),c()}function b(){gc.transforms3d="WebkitPerspective"in document.body.style||"MozPerspective"in document.body.style||"msPerspective"in document.body.style||"OPerspective"in document.body.style||"perspective"in document.body.style,gc.transforms2d="WebkitTransform"in document.body.style||"MozTransform"in document.body.style||"msTransform"in document.body.style||"OTransform"in document.body.style||"transform"in document.body.style,gc.requestAnimationFrameMethod=window.requestAnimationFrame||window.webkitRequestAnimationFrame||window.mozRequestAnimationFrame,gc.requestAnimationFrame="function"==typeof gc.requestAnimationFrameMethod,gc.canvas=!!document.createElement("canvas").getContext,Xb=navigator.userAgent.match(/(iphone|ipod|android)/gi)}function c(){function a(){e.length&&head.js.apply(null,e),d()}function b(b){head.ready(b.src.match(/([\w\d_\-]*)\.?js$|[^\\\/]*$/i)[0],function(){"function"==typeof b.callback&&b.callback.apply(this),0===--f&&a()})}for(var c=[],e=[],f=0,g=0,h=bc.dependencies.length;h>g;g++){var i=bc.dependencies[g];(!i.condition||i.condition())&&(i.async?e.push(i.src):c.push(i.src),b(i))}c.length?(f=c.length,head.js.apply(null,c)):a()}function d(){e(),S(),h(),eb(),Z(!0),setTimeout(function(){fc.slides.classList.remove("no-transition"),cc=!0,t("ready",{indexh:Sb,indexv:Tb,currentSlide:Vb})},1)}function e(){fc.theme=document.querySelector("#theme"),fc.wrapper=document.querySelector(".reveal"),fc.slides=document.querySelector(".reveal .slides"),fc.slides.classList.add("no-transition"),fc.background=f(fc.wrapper,"div","backgrounds",null),fc.progress=f(fc.wrapper,"div","progress",""),fc.progressbar=fc.progress.querySelector("span"),f(fc.wrapper,"aside","controls",'
