<h1><a href="index.html">lib.</a>Events</h1>
<p>
For functional tests it can be useful to simulate event or record and playback events. This module provides
basic support for extracting data from events and serializing events into a JSON format that allows to save
and load sequences of events.
</p>
<p>
Let's look at an example of a HTML structure with click handlers. The click handler actions log messages
that can be tested.
</p>
<pre><code class="html">
<div>
<img id="women" src="examples/women.jpeg"
onclick="record(event); Doctest.log('Lady clicked')"/>
<video id="movie" width="270" data-zoomcap="Kugellaufuhr"
onclick="record(event); Doctest.log('Movie clicked')"
controls>
<source src="examples/movie.mp4" type="video/mp4">
</vide>
</div>
</code></pre>
<div id="example" class="interactive" style="position: relative; width: 100%; border: 1px solid lightgray">
<img
style="margin: 8px"
id="women"
src="examples/women.jpeg"
onclick="record(event); Doctest.log('Lady clicked')"
/>
<video
id="movie"
style="margin: 8px"
width="250"
data-zoomcap="Kugellaufuhr"
onclick="record(event); Doctest.log('Movie clicked')"
onmousedown="record(event)"
onmouseup="record(event)"
controls
>
<source src="examples/movie.mp4" type="video/mp4" />
</video>
</div>
<button onclick="eventRecorder.stopRecording(); eventRecorder.startReplay()">Replay</button>
<script class="doctest">
var eventRecorder = new EventRecorder()
function record(event) {
let target = event.target
target.style.boxShadow = '0px 5px 10px gray'
setTimeout(() => (target.style.boxShadow = ''), 1000)
eventRecorder.record(event)
}
let womenSel = Events.selector(women)
let movieSel = Events.selector(movie)
Events.simulateEvent('click', MouseEvent, { targetSelector: womenSel })
Events.simulateEvent('click', MouseEvent, { targetSelector: movieSel })
Doctest.expectLog('Lady clicked', 'Movie clicked')
</script>
