installation

Git installation

git clone git@github.com:vsilva472/jquery-timeline.git (SSH) ou
git clone https://github.com/vsilva472/jquery-timeline.git (HTTPS)

NPM installation

npm i @vsilva472/jquery-timeline --save

Composer installation

composer require vsilva472/jquery-timeline

CDN installation

https://www.jsdelivr.com/package/npm/@vsilva472/jquery-timeline

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@vsilva472/jquery-timeline@1/dist/jquery.timeline.min.css" />

<script src="https://cdn.jsdelivr.net/npm/@vsilva472/jquery-timeline@1/dist/jquery.timeline.min.js"></script>

Default options

$.fn.timeline.defaults = {
    container : '[data-timeline]',
    apiUrl: null,
    allowRawContent: false,
    transformer: function (data) {
        return data;
    }
};

Note: You can set allowRawContent via data-attribute from the container element just adding the attribute data-timeline-allow-raw-content to the element container.

<div data-timeline="https://yourapi/fetch/timeline/data" data-timeline-allow-raw-content>

Usage

Using with default data selectors

<div data-timeline="http://server/to/fetch/timeline/data"></div>

Note You should call $('selector').timeline(options) only if you are using jQuery timeline without data-attributes

Using with css class selectors

<div class="my-timeline"></div>

<script>
$('.my-timeline').timeline({
    apiUrl: 'https://yourapi/fetch/timeline/data',
    allowRawContent: true 
});
</script>

Using with mixed selectors

<div class="my-timeline" data-timeline-allow-raw-content></div>

<script>
$('.my-timeline').timeline({
    apiUrl: 'https://yourapi/fetch/timeline/data',
});
</script>

The sample above is equivalent to the following configuration

$.fn.timeline.defaults = {
    container : '.my-timeline',
    apiUrl: 'https://yourapi/fetch/timeline/data',
    allowRawContent: true
};

Using a custom transformer

By default jQuery Timeline expect that data received from the ajax request has the following structure:

{
    [year: String] : [
        {
            title: String
            image: String | null,
            description: String | null,
            link: String | null
        }
    ],
    (...)
}

Example:
{
    "1999" : 
    [
        {
            title: 'Lorem ipsum'
            image: null
            description: 'Lorem ipsum dolor sit amet'
            link: 'http://www.google.com'
        }
    ]
}

But each api has your own logic and return your own format, fortunately jQuery Timeline has a method to transform your data before render the content. In this cases you should provide your own transformer witch will adapt the data to the structure described above.

Inside /samples folder you can find a sample that describes this scenario.

<div class="custom-transformer-timeline" style="margin-top: 50px;"></div>

<script>
(function ($) {
const myOwnTransformer = (data) => {
  var transformed = {};

  data.forEach(item => {
    if (!transformed[item.year]) transformed[item.year] = [];

    transformed[item.year].push({
      year: item.year,
      title: item.caption,
      description: item.text || null,
      link: item.url || null,
      image: item.img || null,
    });
  });
  
  return transformed;
};

$(".custom-transformer-timeline").timeline({
  container: '.custom-transformer-timeline',
  apiUrl: 'api-2.json',
  transformer: myOwnTransformer
});

$(".custom-transformer-timeline").on('timeline.after.generate', function () {
  $(this).addClass('timeline'); 
});
})(jQuery);
</script>

Events

jQuery Timeline has a powerful events API that make it extensible and flexible to be integrated with any html page or framework that has jQuery installed.

Advanced Usage

See bellow some jQuery Timeline advanced usage samples

Display a loading

<style>
.hide { display: none; }
</style>
<span class="hide loading">Please wait...</span>
<div data-timeline="https://yourapi/fetch/timeline/data"></div>

<script>
$("[data-timeline]").on('timeline.ajax.before timeline.after.generate', function () {
  $('.loading').toggleClass('hide');
});
</script>

Animations

jQuery Timeline applies the css class .timeline-item to each item of the timeline. This open the opportunity of to do some animations on these items with jQuery and/or CSS.

<style type="text/css">
.timeline-item {
  opacity: 0;
  animation: fadeIn .3s;
  animation-fill-mode: forwards;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}
</style>

<script>
(function ($) {
  $('[data-timeline]').on( 'timeline.after.generate', function ( e, response ) {
    // delay(in seconds) before starts the animation of a item 
    var delay = 0.1;

    $('.timeline-item').each(function () {
      $(this).css('animation-delay', delay + 's');
      delay += 0.1;
    });
  });
} (jQuery));
</script>

Customizing appearance

If you want to customize the elements of the timeline you should overwrite some css values in the following css classes.

/* Responsible for year label style */
.timeline-year-label {} 

/* Responsible for timeline item title */
.timeline-item-title {}

/* Responsible for timeline line (center on desktop and left on mobile)*/
.timeline::before {}

/* Responsible for the image (if an item have one)*/
.timeline-item-image {}

/* Responsible for the description of an item */
.timeline-item-description  {}

/* Responsible for the timeline "dot" at the end of line */
.timeline-end {}

Fetching from Laravel

In some frameworks like Laravel is a common practice the usage of a CSRF-TOKEN for security reasons. This sample shows you how to add X-CSRF-TOKEN before plugin make the request

<div data-timeline="https://yourlaravel/fetch/timeline/data"></div>

<script>
$.ajaxSetup({
    headers: {
      'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
</script>

Google Analytics Integration

Maybe could be interesting to BI team extract some timeline usage informations. The following sample show how you can use jQuery Timeline event's api to send some events to Google Analytics

<div id="xmas-timeline" data-timeline="https://your/api/fetch/timeline/data" class="season-timelines"></div>
<div id="easter-timeline" data-timeline="https://your/api/fetch/timeline/data" class="season-timelines"></div>

<script>
$('.season-timelines').on( 'timeline.after.generate', function ( e, response ) {
  ga( 'send', 'event', 'timeline', 'show', $(this).attr('id'));
});
</script>

Google TagManager Integration

The bellow sample ilustrates the situation above but using Google TagManager.

<div id="xmas-timeline" data-timeline="https://your/api/fetch/timeline/data" class="season-timelines"></div>
<div id="easter-timeline" data-timeline="https://your/api/fetch/timeline/data" class="season-timelines"></div>

<script>
$('.season-timelines').on( 'timeline.after.generate', function ( e, response ) {
  dataLayer.push({
    event: 'sendToGA',
    eventCategory: 'timeline',
    eventAction: 'show',
    eventLabel: $(this).attr('id')
  });
});
</script>
