title: How to get an element from td array by its class name
body: <p>I tried using this statement:</p>
  
  <pre><code>$("td", calendar).getElementsByClassName("today")
  </code></pre>
  
  <p>but I kept getting the error that getElementsByClassName is not a function. </p>
  
  <pre><code>$("td", calendar)
  </code></pre>
  
  <p>gives back an array of "td"'s. Is it possible to access the "today" "td" only using one line, or is a some kind of iteration necessary?</p>
