title: Multiple scroll event definition, and discriminatory event unbinding
body: <p>I ask a specific question about jquery scroll events, but it seems like the answer could have implications to jquery events in general (which I am also interested in knowing).</p>
  
  <p>Suppose that jquery plugin <code>A</code> (e.g., jquery.scrollspy.js) binds a scroll event to <code>$(window)</code></p>
  
  <p>Now say that some site imports plugin <code>A</code>, but it also has its own custom javascript file <code>B</code>, which binds another <code>.scroll()</code> event to <code>$(window)</code>.    </p>
  
  <p>Later on, javascript file <code>B</code> wants to unbind its own scroll event, and leave jquery plugin <code>A</code> intact. How is this done?</p>
  
  <p>and...</p>
  
  <p>Is this method universal to all jquery events?</p>
