<h4>Region events:</h4>
|
||||
|
||||
<ul>
|
||||
<li><code>region-in</code> – When playback enters a region. Callback will receive the <code>Region</code> object.</li>
|
||||
<li><code>region-out</code>– When playback leaves a region. Callback will receive the <code>Region</code> object.</li>
|
||||
<li><code>region-mouseenter</code> - When the mouse moves over a region. Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>
|
||||
<li><code>region-mouseleave</code> - When the mouse leaves a region. Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>
|
||||
<li><code>region-click</code> - When the mouse clicks on a region. Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>
|
||||
<li><code>region-dblclick</code> - When the mouse double-clicks on a region. Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>
|
||||
<li><code>region-created</code> – When a region is created. Callback will receive the <code>Region</code> object.</li>
|
||||
<li><code>region-updated</code> – When a region is updated. Callback will receive the <code>Region</code> object.</li>
|
||||
<li><code>region-update-end</code> – When dragging or resizing is finished. Callback will receive the <code>Region</code> object.</li>
|
||||
<li><code>region-removed</code> – When a region is removed. Callback will receive the <code>Region</code> object.</li>
|
||||
</ul>
|
||||
|
||||
<h4>Regions Plugin</h4>
|
||||
|
||||
<p>Regions are visual overlays on waveform that can be used to play and
|
||||
loop portions of audio. Regions can be dragged and resized.</p>
|
||||
|
||||
<p>Visual customization is possible via CSS (using the selectors
|
||||
<code>.wavesurfer-region</code> and <code>.wavesurfer-handle</code>).</p>
|
||||
|
||||
<p>To enable the plugin, add the script <code>plugin/wavesurfer.regions.js</code> to
|
||||
your page.</p>
|
||||
|
||||
<p>After doing that, use <code>wavesurfer.addRegion()</code> to create Region objects.</p>
|
||||
|
||||
<h5>Exposed Methods</h5>
|
||||
|
||||
<ul>
|
||||
<li><code>addRegion(options)</code> – Creates a region on the waveform. Returns a <code>Region</code> object. See <a href="#region-options">Region Options</a>, <a href="#region-methods">Region Methods</a> and <a href="#region-events">Region Events</a> below.
|
||||
|
||||
<ul>
|
||||
<li><strong>Note:</strong> You cannot add regions until the audio has finished loading, otherwise the <code>start:</code> and <code>end:</code> properties of the new region will be set to <code>0</code>, or an unexpected value.</li>
|
||||
</ul></li>
|
||||
<li><code>clearRegions()</code> – Removes all regions.</li>
|
||||
<li><code>enableDragSelection(options)</code> – Lets you create regions by selecting.
|
||||
areas of the waveform with mouse. <code>options</code> are Region objects' params (see <a href="#region-options">below</a>).</li>
|
||||
<li><code>disableDragSelection()</code> - Disables ability to create regions.</li>

||||
</ul>
