|
|
|
+
|
|
|
+You can swipe to navigate through a presentation on any touch-enabled device. Horizontal swipes change between horizontal slides, vertical swipes change between vertical slides. If you wish to disable this you can set the `touch` config option to false when initializing reveal.js.
|
|
|
+
|
|
|
+If there's some part of your content that needs to remain accessible to touch events you'll need to highlight this by adding a `data-prevent-swipe` attribute to the element. One common example where this is useful is elements that need to be scrolled.

|
|
+### Lazy Loading
|
|
|
+
|
|
|
+When working on presentation with a lot of media or iframe content it's important to load lazily. Lazy loading means that reveal.js will only load content for the few slides nearest to the current slide. The number of slides that are preloaded is determined by the `viewDistance` configuration option.
|
|
|
+
|
|
|
+To enable lazy loading all you need to do is change your "src" attributes to "data-src" as shown below. This is supported for image, video, audio and iframe elements. Lazy loaded iframes will also unload when the containing slide is no longer visible.
|
|
|
+
|
|
|
+```html

|
|

+### postMessage API
|
|
|
+The framework has a built-in postMessage API that can be used when communicating with a presentation inside of another window. Here's an example showing how you'd make a reveal.js instance in the given window proceed to slide 2:
|
|
|
+
|
|
|
+```javascript
|
|
|
+<window>.postMessage( JSON.stringify({ method: 'slide', args: [ 2 ] }), '*' );
|
|
|
+```
|
|
|
+
|
|
|
+When reveal.js runs inside of an iframe it can optionally bubble all of its events to the parent. Bubbled events are stringified JSON with three fields: namespace, eventName and state. Here's how you subscribe to them from the parent window:
|
|
|
+
|
|
|
+```javascript
|
|
|
+window.addEventListener( 'message', function( event ) {
|
|
|
+ var data = JSON.parse( event.data );
|
|
|
+ if( data.namespace === 'reveal' && data.eventName ='slidechanged' ) {
|
|
|
+ // Slide changed, see data.state for slide number
|
|
|
+ }
|
|
|
+} );
|
|
|
+```
|
|
|
+
|
|
|
+This cross-window messaging can be toggled on or off using configuration flags.
|
|
|
+
|
|
|
+```javascript
|
|
|
+Reveal.initialize({
|
|
|
+ ...,
|
|
|
+
|
|
|
+ // Exposes the reveal.js API through window.postMessage
|
|
|
+ postMessage: true,
