HTML / JavaScript before </body>

Question

How can I add HTML / JavaScript code before the closing "</body>" Tag via Plugin? 

I do NOT want to use the "Custom HTML at bottom of every page" option in the admin backend.

Answer 1

found it. 

    function body_suffix() {        

       $this->output('foo baa');         

    }

via plugin? What is the Plugin?

I wrote an plugin for syntaxhighlighting.

Needed this code after the main content:

<script type="text/javascript">
    SyntaxHighlighter.all();
</script>

in my plugin I do this:

function body_suffix() {
    $this->output('<script type="text/javascript">SyntaxHighlighter.all();</script>');
}
