<h1>Event System</h1>

<h2><a class="anchor" name="syntheticevent"></a>SyntheticEvent <a class="hash-link" href="#syntheticevent">#</a></h2>
|
|
<p>Your event handlers will be passed instances of <code>SyntheticEvent</code>, a cross-browser wrapper around the browser's native event. It has the same interface as the browser's native event, including <code>stopPropagation()</code> and <code>preventDefault()</code>, except the events work identically across all browsers.</p>
|
|
|
|
<p>If you find that you need the underlying browser event for some reason, simply use the <code>nativeEvent</code> attribute to get it. Every <code>SyntheticEvent</code> object has the following attributes:</p>
|
|

different browsers.</p>
