Timeline : a linear representation of important events in the order in which they occurred. [^1]
Demo
Glossary
Time unit : Or t.u. It's the unit used to measure time in the timeline. By default are the same units that uses Data object, that is milliseconds.
Time event : An event in time with a title and start date. Optionally could have a end date. For example :
{
'title': "RMS Caronia reports",
'start': "1912-04-14T09:00:00.000Z",
},
{
'title': "Sinking of the Titanic",
'start': "1912-04-14T23:39:00.000Z",
'end': "1912-04-15T02:28:00.000Z"
},
Time mark o mark : Each mark with label on the time axis
Time window : Interval of time actually visible on the timeline
Time units per pixels : It's the result of the quotient of the time window and the widget width. This represents how many time units represents a pixel on screen
Usage
Include the JavaScript module using the <script>
tag.
<script src="bluebox.js" type="module"><script/>
And insert the bluebox tag in your HTML :
<bluebox-tl />
Loading the timeline dataset
There 3 ways : src attribute, embedding JSON, and using JavaScript
Src attribute :
<bluebox-tl src="URL_THAT_RETURNS_JSON" />
Embed JSON with a script tag inside :
<bluebox-tl >
<script type="application/json">
[
{
'title': "...",
'start': ...,
'end': ...,
},
...
]
</script>
</bluebox-tl>
Using JavaScript :
const tl = document.querySelector('bluebox-tl');
tl.dataset = [
{
'title': "...",
'start': ...,
'end': ...,
},
...
];
Or fetching with JavaScript :
const tl = document.querySelector('bluebox-tl');
tl.fetch("URL_THAT_RETURNS_JSON", {FETCH_OPTONS})
.catch(err => console.log("Something bad happened"));
Tag parameters
| Attribute | Description | |-------------------|-----------------------------------------------------------| | src | An url that returns a valid JSON to be parsed as dataset | | selected-index =0.1 | Current time event index selected by the user | | zoom-factor = 1 | Relative scaling factor. 1 shows the entire timeline in the widget width | | min-factor = 0.5 | Minimal zoom factor. | | max-factor = 16 | Max zoom factor. | | max-rows = 6 | Max number of rows before wrapping up | | time-unit | T.u. being used by the timeline. | | mark-step-[0-5] | Number of t.u. between each time mark | | mark-threshold-[0-5] | Max number of t.u. per pixels before hiding this marks | | date-time-format | JSON representation of Intl.DateTimeFormat options, for the configuration of the default date/time formater. | | debug=[false, true, trace] | Enables console logging for debugging |
