title: Make a submit input un-clickable
body: <p>I have the following input:</p>
  
  <pre><code>&lt;input type="submit" name="next" value="Next"&gt;
  </code></pre>
  
  <p>How would I make this item un-clickable via jQuery? (i.e., it may only be clicked <strong>after</strong> certain validation criteria are met) ?</p>
