Need help using jQueryUi in Plone - jquery-ui

Question

I'm new to Plone and jQueryUI, and have not been able to get any jQueryUI working on a Plone page.
I installed Plone 4 (4.1.4 41143) and jQueryUI 1.8.16 (http://plone.org/products/collective.js.jqueryui),
Under Zope Management Interface > portal_javascripts, collective.js.jqueryui.custom.min.js is present and enabled.
To try to implement the example from http://jqueryui.com/demos/button/, I placed in the body text of a Plone page:
<script type="text/javascript">
jQuery({function($) {
$( "input:submit, a, button", ".demo" ).button();
$( "a", ".demo" ).click(function() { return false; });
});
</script>
<DIV class=demo>
<BUTTON type=submit>A button element</BUTTON> <INPUT value="A submit button" type=submit> An anchor
</DIV><!-- End demo -->
but the resulting page does not show the expected result.
I've tried replacing "jQuery" in the code above with "$", "collective.js.jqueryui.custom.min", but nothing has worked yet.
I was able to get some jQueryUI working outside of Plone, but would be interested in knowing how to use it within Plone. Any help appreciated.

Answer 1

The content of your script tags is probably being deleted by Plone's HTML filtering.
You can change that in "Site Setup", "HTML Filtering". (The dialog there is confusing, you have to click two buttons. First remove from 'nasty tags', then 'save' at the bottom of page.)
Be aware though, that there are good security reasons for not allowing users to use script, embed and other tags. It can lead to all kind of trouble, for instance when they are also allowed in comments, or less experienced users copy/paste dangerous code.
If you're just practicing, and not putting your site on the big bad Internet, it can be fine, but if you start deploying a real site it is much better to put script stuff into page templates of your own file-based add-on product.

Answer 2

Your syntax within the script tag is incorrect. Try this:
jQuery(function($) {
$( "input:submit, a, button", ".demo" ).button();
$( "a", ".demo" ).click(function() { return false; });
})($);​

Answer 3

Yes, you may need to allow script tags as described above, but the example still did not work for me until I replaced the word jQuery with the $ sign, at least when using collective.js.jqueryui 1.8.16.9 on Plone 4.2.1.1.
<script>
$(function() {
$( "#progressbar1" ).progressbar();
$( "#slider" ).slider();
$( "input:submit, a, button", ".demo" ).button();
$( "a", ".demo" ).click(function() { return false; });
});
</script>
Putting ($) just before the semicolon on the line above also worked but I saw no difference.
The script worked on a file system page template even when script was included in the "nasty tags" list. Also, the script can be inserted into the document's head with the following in a page template:
<metal:slot fill-slot="javascript_head_slot">
<script>
$(function() {
$( "#slider" ).slider();
$( "#progressbar1" ).progressbar();
$( "input:submit, a, button", ".demo" ).button();
$( "a", ".demo" ).click(function() { return false; });
});
</script>
</metal:slot>
(I'd love to hear if there is a more appropriate prefix, but I don't really know javascript.)

Answer 4

I've just had a similar issue trying to get my scripts and jquery UI to work with a plone/zope setup. The solution was to register them in the javascript registry (/portal_javascripts).
The scripts themselves were added to /portal_skins/custom which is also where the homepage I was working on resides.
Script tags are filtered out from the source as already mentioned above, and the scripts from the registry automatically added instead.
Keep in mind also that order is important in the javascript registry.
Hope this is of some help to other users who come across this question,.
