title: Toggle input disabled attribute using jQuery
body: <p>Here is my code:</p>
  
  <pre><code>$("#product1 :checkbox").click(function(){
      $(this)
          .closest('tr') // Find the parent row.
              .find(":input[type='text']") // Find text elements in that row.
                  .attr('disabled',false).toggleClass('disabled') // Enable them.
                  .end() // Go back to the row.
              .siblings() // Get its siblings
                  .find(":input[type='text']") // Find text elements in those rows.
                  .attr('disabled',true).removeClass('disabled'); // Disable them.
  });
  </code></pre>
  
  <p>How do I toggle <code>.attr('disabled',false);</code>?</p>
  
  <p>I can't seem to find it on Google.</p>
