1. better access to the TOC from anywhere on the page…
2. An example of this:

http://developer.apple.com/technotes/tn/tn1132.html#top

Don't create the link “back to top” for header level 1… Create link “back to top” before each title…

The example is written for DokuWiki 2008-05-05 and will not fit directly into recent versions.

In inc\parser\xhtml.php change the function header by this one :

(line 134)

    function header($text, $level, $pos) {
 
        $hid = $this->_headerToLink($text,true);
 
        //only add items within configured levels
        $this->toc_additem($hid, $text, $level);
 
        // write the header
        $this->doc .= DOKU_LF;
		if($level > 1){
				$this->doc .= html_topbtn2();
		}
		$this->doc .='<h'.$level.'><a name="'.$hid.'" id="'.$hid.'">';
        $this->doc .= $this->_xmlEntities($text);
        $this->doc .= "</a></h$level>".DOKU_LF;
    }

then : create the function “html_topbtn2” under “html_btn” in “inc\html.php”

(line 165)

function html_topbtn2(){
  global $lang;
 
  $ret  = '';
  $ret  = '<a href="#dokuwiki__top" onclick="window.scrollTo(0, 0)" title="'.$lang['btn_top'].'" >'. $lang['btn_top'].' </a>';
 
  return $ret;
}

Somewhere else i also rewrite:

$lang['btn_top'] = '['.$lang['btn_top'].']';

I use this with the monobook template, looks nice.

Would be good to know what path you refer here. I did not find the right file or section or the file changed heavily in the meantime.

Isn't this essentially superseded by the Up Arrow plugin? — Luis Machuca Bezzaza 2009/09/21 19:37

No, adding this code automatically generates a back_to_top link before headers <h2>, <h3>, etc. All except for <h1>.
