1) If I want to include my own JavaScript files I have to include them in the footer becuase silverstripe does not display the <script> tags after the CSS in the header. Is there a way of including <script> tags correctly in the header or at lest just my <script> tags?

2) I also see prototype.js has been snuck in for the latest release. Shame as jQuery has larger support and growing user base. Using jQuery scripts together with Prototype needs a no conflict (and a larger down load times). Not a major issue but a bit of pain to get working with all jQuery plugins.

Or maybe I am just having a bad day :-)

Oh it gets worse.

When I move my JS includes to the footer Sapphire inserts it's script (includes prototype.js that clashes $ with jQuery) in between my files. This is terrible if your using jQuery. Why does Silverstripe make this such a pain in the ass?

Source order of JS is such an overlooked factor in Silverstripe and one the dev team fail to understand hence why dumping scripts before the </body> tag.

Oh it gets even worse.

Same issue with Style sheets. Say you want to insert this in the header:

<!--[if IE 6]><style type="text/css">@import url(/themes/flipside/css/ie6.css);</style><![endif]-->
but it appears before the standard CSS includes in the source.

The Requirements engine in SS writes all JS (unless write_js_to_body is set to false) before the closing </head> in the order

JS Files
JS Custom Scripts
Other Header Element

This is terrible if your using jQuery. Why does Silverstripe make this such a pain in the ass?

We use jQuery on mostly all of our sites without any issues - you can wrap the jquery in a closure see You can also configure SS to disable the prototype form validation and block prototype files if needed. To disable prototype validation you can set


in you _config file and block any files that try and sneak through by using Requirements::block('path/to/file'); In the next major version of SilverStripe we will have hopefully got rid of all this prototype code. We're still going through the transition phase so its a tad messy at the moment (2.4 has a bit of JS cleanup in it).

As for including conditional stylesheets - my work around is just use a more specific css selector in the ie stylesheet. A wrapper for conditional stylesheets is pending some more enhancements to the template engine I doubt the SSViewer tweaks will happen very soon but you should be able to use more specific selectors for now. If you don't like that then bypass the css requirements style and just use link tags :D

Thanks for the work arounds.
