Jquery check if element is visible in viewport

Function to check if the div class "media" is within the browsers visual viewport regardless of the window scroll position.

<HTML>
<HEAD>
  <TITLE>My first HTML document</TITLE>
</HEAD>
<BODY>
  <div class="main">
   <div class="media"></div>
  </div>

</BODY>
</HTML>

Trying to use this plugin https://github.com/customd/jquery-visible with this function but I don't know how to make it work.

$('#element').visible( true );

Solution

According to the documentation for that plugin, .visible() returns a boolean indicating if the element is visible. So you'd use it like this:

if ($('#element').visible(true)) {
    // The element is visible, do something
} else {
    // The element is NOT visible, do something else
}
