title: If option value is visible
body: <p>I want a function to be executed if a specific select option is visible.
  I have tried the following code:</p>
  
  <pre><code>if ($(("#daychoise option[value='monday2']").is(':visible'))) {
  
  }
  </code></pre>
  
  <p>That didn't work and I got the following error in the console:</p>
  
  <p>Uncaught TypeError: Object #daychoise option[value='monday2'] has no method 'is'</p>
  
  <p>So how do I check if a select option is visible?</p>
  
  <p>Thanks in advance</p>
