What is the "click.smoothscroll" event in jQuery?
<p>I have seen the following code:</p>

<pre><code>$('a[href^="#"]').on('click.smoothscroll',function(e) {...}
</code></pre>

<p>I do not understand what the click.something is.
I know the function like this: </p>

<pre><code>$('a[href^="#"]').on('click',function(e) {...}
</code></pre>

<p>what is the something/smoothscroll doing? is this a kind of event?</p>
