title: Cursor position issues after using jquery
body: <pre><code>&lt;?php echo $this-&gt;Html-&gt;script('balaashjquery'); ?&gt;
   &lt;script type="text/javascript"&gt;
    jQuery(function(){
  
  
       $('#iso').blur(function(){
        $isoval = $('#iso').val();
        if($isoval ==""){
         alert('iso field should not be empty');
        }
        $('#iso').focus();
      });
  </code></pre>
  
  <p>i have used similar type of jquery for all my fields .
  now when i am leaving any field blank it is showing a validation message but after filling it i am not able to move to the next field either by using tab button nor mouse pointer</p>
