Question

In my code I’m using a link button called updateLogButton which shows/hides a div. Because I use a link button everytime its clicked focus is moved to the beginning of the page. How can I stop this default behaviour?

Jquery snippet:

$('#updateLogText').hide();

$('#updateLogButton').click(function() {

    if ($('#updateLogText').is(':visible')){

        //hide div if content is visible
        $('#updateLogText').fadeOut();

    }else{

        $('#updateLogText').fadeIn();       
    }

});

HTML code:

<tr>
    <td><a href="#"  id="updateLogButton">Update Log</a></td>
</tr>
<tr>
    <td colspan="3" >
        <div id="updateLogText" style="width:100%;">
            <?php echo $data['updates']; ?>
        </div>

    </td>
</tr>

To prevent the default action when the link is clicked you can return false from the click handler or call event.preventDefault where event is the event object passed to the click handler.

$('#updateLogText').hide();

$('#updateLogButton').click(function(event) {

    if ($('#updateLogText').is(':visible')){

        //hide div if content is visible
        $('#updateLogText').fadeOut();

    }else{

        $('#updateLogText').fadeIn();       
    }
    event.preventDefault();
    //or return false;
});
