The content of this div will be used as the slide description

You can add links and any HTML you want

``` ## Slide Options You can specify some options to each individual slide, the available options are: - title - alt - description - descPosition - type - effect - width - height - zoomable - draggable ```html ``` ## Lightbox Options Example use of the options. ```javascript const lightbox = GLightbox({ touchNavigation: true, loop: true, autoplayVideos: true }); // Instead of using a selector, define the gallery elements const myGallery = GLightbox({ elements: [ { 'href': 'https://picsum.photos/1200/800', 'type': 'image', 'title': 'My Title', 'description': 'Example', }, { 'href': 'https://picsum.photos/1200/800', 'type': 'image', 'alt': 'image text alternatives' }, { 'href': 'https://www.youtube.com/watch?v=Ga6RYejo6Hk', 'type': 'video', 'source': 'youtube', //vimeo, youtube or local 'width': 900, }, { 'content': '

This will append some html inside the slide

' // read more in the API section }, { 'content': document.getElementById('inline-example') // this will append a node inside the slide }, ], autoplayVideos: true, }); myGallery.open(); // If later you need to modify the elements you can use setElements myGallery.setElements([...]); ``` | Option | Type | Default | Description | | --- | --- | --- | --- | | selector | string | `.glightbox` | Name of the selector for example '.glightbox' or 'data-glightbox' or '\*[data-glightbox]' | | elements | array | `null` | Instead of passing a selector you can pass all the items that you want in the gallery. | | skin | string | `clean` | Name of the skin, it will add a class to the lightbox so you can style it with css. | | openEffect | string | `zoom` | Name of the effect on lightbox open.

You can use the on() API method or once(). ```javascript const lightbox = GLightbox(); lightbox.on('open', () => { // Do something }); lightbox.once('slide_changed', () => { // Do something just one time }); ``` | Event Type | Description | | ------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | open | Provide a function when the lightbox is opened. | | close | Provide a function when the lightbox is closed. | | slide_before_change | Trigger a function before the slide is changed. | | slide_changed | Trigger a function after the slide is changed. | | slide_before_load | Trigger a function before a slide is loaded for the first time, the function will only be called once | | slide_after_load | Trigger a function after a slide is loaded and it's content is set for the first time, the function will only be called once | | slide_inserted | Trigger a function after a slide is inserted using insertSlide. | | slide_removed | Trigger a function after a slide is removed` | ```javascript const lightbox = GLightbox(); lightbox.on('slide_before_change', ({ prev, current }) => { console.log('Prev slide', prev); console.log('Current slide', current); // Prev and current are objects that contain the following data const { slideIndex, slideNode, slideConfig, player, trigger } = current; // slideIndex - the slide index // slideNode - the node you can modify // slideConfig - will contain the configuration of the slide like title, description, etc. // player - the slide player if it exists otherwise will return false // trigger - this will contain the element that triggers this slide, this can be a link, a button, etc in your HTML, it can be null if the elements in the gallery were set dinamically }); lightbox.on('slide_changed', ({ prev, current }) => { console.log('Prev slide', prev); console.log('Current slide', current); // Prev and current are objects that contain the following data const { slideIndex, slideNode, slideConfig, player, trigger } = current;

} player.on('play', (event) => { console.log('Started play'); }); player.on('volumechange', (event) => { console.log('Volume change'); }); player.on('ended', (event) => { console.log('Video ended'); }); } }); // Useful to modify the slide // before it's content is added lightbox.on('slide_before_load', (data) => { // data is an object that contain the following const { slideIndex, slideNode, slideConfig, player, trigger } = data; // slideIndex - the slide index // slideNode - the node you can modify // slideConfig - will contain the configuration of the slide like title, description, etc. // player - the slide player if it exists otherwise will return false // trigger - this will contain the element that triggers this slide, this can be a link, a button, etc in your HTML, it can be null if the elements in the gallery were set dinamically }); // Useful to execute scripts that depends // on the slide to be ready with all it's content // and already has a height // data will contain all the info about the slide lightbox.on('slide_after_load', (data) => { // data is an object that contain the following const { slideIndex, slideNode, slideConfig, player, trigger } = data; // slideIndex - the slide index // slideNode - the node you can modify // slideConfig - will contain the configuration of the slide like title, description, etc. // player - the slide player if it exists otherwise will return false // trigger - this will contain the element that triggers this slide, this can be a link, a button, etc in your HTML, it can be null if the elements in the gallery were set dinamically }); // Trigger a function when a slide is inserted lightbox.on('slide_inserted', (data) => { // data is an object that contain the following const { slideIndex, slideNode, slideConfig, player, trigger } = data; // slideIndex - the slide index // slideNode - the node you can modify // slideConfig - will contain the configuration of the slide like title, description, etc. // player - the slide player if it exists otherwise will return false // trigger - null }); // Trigger a function when a slide is removed lightbox.on('slide_removed', (index) => { // index is the position of the element in the gallery }); ``` ## Video player GLightbox includes "[Plyr](https://plyr.io/)" the best player out there, you can pass any Plyr option to the player, view all available options here [Plyr options](https://github.com/sampotts/plyr). GLightbox will only inject the player library if required and only when the lightbox is opened. **Internet Explorer 11. If you need support for this browser you need to set the js url to use the polyfilled version. This is not the default because IE11 is ancient and we need to let it die.** ### Autoplay for mobile/tablet Please note, autoplay is blocked in some browsers, there’s nothing we can do to change that unfortunately, the browser will decide if your video can be autoplayed. Please do not post issues about this, instead inform yourself about this topic: - [https://webkit.org/blog/6784/new-video-policies-for-ios/](https://webkit.org/blog/6784/new-video-policies-for-ios/) - [https://developers.google.com/web/updates/2017/09/autoplay-policy-changes](https://developers.google.com/web/updates/2017/09/autoplay-policy-changes) - [https://hacks.mozilla.org/2019/02/firefox-66-to-block-automatically-playing-audible-video-and-audio/](https://hacks.mozilla.org/2019/02/firefox-66-to-block-automatically-playing-audible-video-and-audio/) they decide if a video can be autoplayed based in a few rules ``` plyr: { js: 'https://cdn.plyr.io/3.6.2/plyr.polyfilled.js', .... ``` ```javascript const lightbox = GLightbox({ plyr: { css: 'https://cdn.plyr.io/3.5.6/plyr.css', // Default not required to include js: 'https://cdn.plyr.io/3.5.6/plyr.js', // Default not required to include config: { ratio: '16:9', // or '4:3' muted: false, hideControls: true, youtube: { noCookie: true, rel: 0, showinfo: 0, iv_load_policy: 3 }, vimeo: { byline: false, portrait: false, title: false, speed: true, transparent: false } } } }); ``` ## API There are methods, setters and getters on a GLightbox object. The easiest way to access the GLightbox object is to set the return value from your call to a variable. For example: ```javascript const lightbox = GLightbox({ ...options }); ``` ## Methods Example method use: ```javascript lightbox.nextSlide(); // Go to next slide lightbox.close(); // Close the lightbox ``` | Option | Parameters | Description | | ---------------------- | ------------------ | -------------------------------------------------------------------------- | | open | `node` | Open the lightbox, you can optionally pass a node. | | openAt | `number` | Open at specific index. | | close | `-` | Close the lightbox. | | reload | `-` | Reload the lightbox, after inserting content with ajax. | | destroy | `-` | Destroy and remove all attached events. | | prevSlide | `-` | Go to the previous slide. | | nextSlide | `-` | Go to the next slide. | | goToSlide | `number` | Index of the slide. | | insertSlide | `object, index` | Insert a slide at the specified index. | | removeSlide | `index` | Remove slide at the specified index. | | getActiveSlide | `-` | Get active slide. It will return the active node. | | getActiveSlideIndex | `-` | Get active slide. It will return the active slide index. | | slidePlayerPlay | `number` | Play video in the specified slide. | | slidePlayerPause | `number` | Pause video in the specified slide. | | getSlidePlayerInstance | `node, index` | Get the player instance of the specified slide. | | getAllPlayers | `-` | Get all players instance. | | setElements | `[]` | Update the lightbox gallery elements. | | on | `string, function` | Set an event listener. See Events section | | once | `string, function` | Set an event listener that will be triggered only once. See Events section | ```javascript // Example set custom gallery items // This overwrites all the items in the gallery lightbox.setElements([ { 'href': 'https://picsum.photos/1200/800', 'type': 'image' // Type is only required if GLightbox fails to know what kind of content should display }, { 'href': 'https://www.youtube.com/watch?v=Ga6RYejo6Hk', 'type': 'video', // Type is only required if GLightbox fails to know what kind of content should display 'width': '900px', }, { 'content': '

some html to append in the slide

', 'width': '900px', } ]); // Insert a single slide at the end of all the items, lightbox.insertSlide({ href: 'video url...', width: '90vw' }); // Insert a single slide at index 2 or pass 0 to add it at the start lightbox.insertSlide({ href: 'video url...', width: '90vw' }, 2); // You can insert a slide with a defined html lightbox.insertSlide({ content: '

some html to append in the slide

', width: '90vw' }, 2); // Or if you prefer you can pass a node // and it will be inserted in the slide lightbox.insertSlide({ content: document.getElementById('inline-example'), width: '90vw' }, 2); // Remove the slide at index 2 lightbox.removeSlide(2); // Open the lightbox lightbox.open(); // You can also open the lightbox at a specific index lightbox.openAt(2); // So imagine that you are making an ajax request that returns some html // You can create an empty instance and append the content once is returned const ajaxExample = GLightbox({ selector: null }); // or you can set the selector empty selector: '' doAjaxCall({...}).then(response => { ajaxExample.insertSlide({ width: '500px', content: response.html }); ajaxExample.open(); }) // Or you could use the set elements method to empty all the slides if any doAjaxCall({...}).then(response => { ajaxExample.setElements([ { content: response.html } ]); ajaxExample.open(); }) ``` ## Animations Animations are created with CSS, each effect has an in and out value and they are used to attach the correct classes to the node. For example if you are using ```javascript const glightbox = GLightbox({ openEffect: 'zoom', closeEffect: 'fade', cssEfects: { // This are some of the animations included, no need to overwrite fade: { in: 'fadeIn', out: 'fadeOut' }, zoom: { in: 'zoomIn', out: 'zoomOut' } } }); ``` The open effect will use cssEfects.zoom.in and will add the class gzoomIn, if you take a look at the CSS you'll see: ```javascript .gzoomIn { animation: gzoomIn .5s ease; } @keyframes gzoomIn { from { opacity: 0; transform: scale3d(.3, .3, .3); } to { opacity: 1; } } ``` ### Adding a custom animation You can create any animation you want, you can find some inspiration in the Animate.css library, for example you can add the bounce animation like this: ```javascript const glightbox = GLightbox({ openEffect: 'bounce', // Define that we want the bounce animation on open cssEfects: { // register our new animation bounce: { in: 'bounceIn', out: 'bounceOut' } } }); ``` ```css /*A g will be appended to the animation name so bounceIn will become gbounceIn */ .gbounceIn { animation: bounceIn 1.3s ease; } @keyframes bounceIn { from, 20%, 40%, 60%, 80%, to { animation-timing-function: cubic-bezier(0.215, 0.61, 0.355, 1); } 0% { opacity: 0; transform: scale3d(0.3, 0.3, 0.3); } 20% { transform: scale3d(1.1, 1.1, 1.1); } 40% { transform: scale3d(0.9, 0.9, 0.9); } 60% { opacity: 1; transform: scale3d(1.03, 1.03, 1.03); } 80% { transform: scale3d(0.97, 0.97, 0.97); } to { opacity: 1; transform: scale3d(1, 1, 1); } } ``` ## Themeable You can completely customize the structure of GLightbox and use CSS to change any part you want. ```javascript const customLightboxHTML = `

`; let customSlideHTML = `

`; const glightbox = GLightbox({ lightboxHTML: customLightboxHTML, slideHTML: customSlideHTML, skin: 'supercool' }); ``` You can also define a skin name and the lightbox will append the class name "glightbox-supercool" so you can customize it with CSS, this will leave a barebones structure so you can change the buttons appearance, etc. ## Development ```bash $ npm install $ npm run watch ``` ## Browser Support GLightbox was tested in the following browsers. - Safari - Mobile Safari - Opera - Edge - Firefox - Internet Explorer 11 It will work in any browser that supports CSS Flexbox ## Contributing Feel free to report any issues!
