Hi Folk

I have the following random Javascript lines showing up in my page code:

<script type="text/javascript" src="jsparty/behaviour.js"></script>
<script type="text/javascript" src="jsparty/prototype.js"></script>
<script type="text/javascript" src="jsparty/scriptaculous/effects.js"></script>
<script type="text/javascript" src="cms/javascript/PageCommentInterface.js"></script>

Where do these lines come from? I dont really need all that Javascript. I never asked them to be there.... Furthermore, if they need to be there, then I would at least have the opportunity to move them up so that my own JS can come afterwards...

Any hints greatly appreciated.

Thank you

Nicolaas

Im taking a guess but I would think those js's are for the commenting system (eg leaving a comment on a page if you enable that). you probably dont want to be playing around with them if you need the commenting feature.

exactly. as soon as you include $PageComments somewhere in your template, the PageCommentInterface is automatically loaded, which requires these javascript-files.
see cms/code/sitefeatures/PageCommentInterface.php->PostCommentForm()

The Requirements class is what facilitates this.

You can call this in your controller's init() method, or anywhere else in your code:
Requirements::javascript('mysite/javascript/some-file.js');

It will then be added to a list of include tags that are inserted just before the </head> tag.

We do this so that any piece of PHP code can demand that a particular javascript / css file be included. For example, if you make use a TreeMultiselectField, it will include the javascript required to support this.
