Re: ajax Update in a page with 2 divs

Hello.

When I have to update two (or more) different elements, but both of them with different content, I simply only set 'update' in a form on a element where I have to display more complex data (for example from database), and then I update second div using JavaScript (in a view of updated element).

For example:
I have a submit comment ajax form, and after the form is submitted - I want to save comment to database and display refreshed list of comments and also the message "Comment has been added" (but in a different place than updated list of comments).

Let's assume that the view (list of comments and comment submit form) looks like this:

<div>Add comment</div>
<div id="message"></div>
<div>
   <?php echo $this->Form->create('Comment')?>
   <?php echo $this->Form->textarea('comment')?>
   <?php echo $this->Js->submit('Add comment', array(
          'url' => '/comments/add/'.$p['Post']['id'],
          'update' => '#comments_list',
          'evalScripts' => true,
        ));?>
</div>
<div id="comments_list">
   //here goes the list of comments
</div>

After you submit a form, the action "add" in Comments controller is being done - a comment is entered to a database and you retrieve updated list of comments from database.
The div with "comments_list" id is updated with the list of updated comments.
So your "Comments/add.ctp" view contains list of comments and a JavaScript code to update "message" div with an info that comment has been added:

//here goes the list of comments
<script type="text/javascript">
  document.getElementById('message').innerHTML='<div class="message">Comment has been added. Thank you!</div>';
</script>

You have to remember to add 'evalScripts' => true to the submit button, otherwise JS code won't be executed.

Hope this helps a bit.
