title: Custom Tooltip function from title attribute
body: <p>I have a function for creating a tooltip from a title. I am trying to wrap this function in an if statement that checks the title length before returning the tooltip. But it doesn't seem to want to return anything. Is there a better way to do this then with an if statement?</p>
  
  <pre><code>$(document).ready(function() {
  
   if ($('#menu-headermenu a').attr('title').length == 0) {
  
   return null;
  
  } else {
  
  //Select all anchor tag with rel set to tooltip
  $('#menu-headermenu a').mouseover(function(e) {
  
      //Grab the title attribute's value and assign it to a variable
      var tip = $(this).attr('title');    
  
      //Remove the title attribute's to avoid the native tooltip from the browser
      $(this).attr('title','');
  
      //Append the tooltip template and its value
      $(this).append('&lt;div id="tooltip"&gt;&lt;p&gt;Take me to:&lt;p&gt;&lt;div class="tooltipcontent"' + tip + '&lt;/div&gt;&lt;/div&gt;');     
  
      //Set the X and Y axis of the tooltip
      $('#tooltip').css('top', e.pageY + 10 );
      $('#tooltip').css('left', e.pageX + 20 );
  
      //Show the tooltip with faceIn effect
      $('#tooltip').fadeIn('500');
      $('#tooltip').fadeTo('10',0.8);
  
  }).mousemove(function(e) {
  
      //Keep changing the X and Y axis for the tooltip, thus, the tooltip move along with the mouse
      $('#tooltip').css('top', e.pageY + 10 );
      $('#tooltip').css('left', e.pageX + 20 );
  
  }).mouseout(function() {
  
      //Put back the title attribute's value
      $(this).attr('title',$('div.tooltipcontent').html());
  
      //Remove the appended tooltip template
      $(this).children('div#tooltip').remove();
  
  });
  
  }
  });
  </code></pre>
