Subject: RE: [docbook-apps] generating javascript navigation


Skopik,

 

I ran into that recently too… and found the cause and the solution in an earlier post by Bob Stayton on this newsgroup:

 

The DocBook titlepage specs include a separator item after the title pages:

 

  <t:titlepage-separator>

      <fo:block break-after="page"/>

  </t:titlepage-separator>

 

This is supposed to just force a page break after the end of the verso

titlepage content.  This works fine in XEP and Antenna House, but FOP

creates an extra page with it.  This is a long standing bug in FOP's

handling of breaks… Making this an empty element would eliminate the extra

blank page before the TOC:

 

  <t:titlepage-separator>

  </t:titlepage-separator>

 

Hope that helps…

 

Alan

Subject: [docbook-apps] generating javascript navigation

 

Hello,

 

recently I looked at a JavaScript TOC navigation plugin for DITA which uses the Yahoo treeview library (http://developer.yahoo.com/yui/treeview/). I would like to use this library for docbook html output and generate javascript navigation tree.

 

The navigation is contained in a javascript file and has following structure:

 

var objd0 = { label: "Book ", href:"index.html", target:"content"};

var d0 = new YAHOO.widget.TextNode(objd0, root, false);

 

var objd0e5 = { label: "Preface ", href:"pr01.html", target:"content"};

var d0e5 = new YAHOO.widget.TextNode(objd0e5, root, false);

 

var objd0e10 = { label: "Chapter 1 ", href:"ch01.html", target:"content"};

var d0e10 = new YAHOO.widget.TextNode(objd0e10, root, false);

 

var objd0e13 = { label: "Section 1 ", href:"ch01.html#d0e13", target:"content"};

var d0e13 = new YAHOO.widget.TextNode(objd0e13, root, false);

 

So far I have been able to generate working javascript but was not able to get the right hierarchical structure of the tree. When generating for example the section node I need to get the ID of the parent element (chapter, other section ect.). Consider following example:

 

Having Chapter 1 and Section 1 I need to get the recursion the right way. While component titles should have the „root“ value

 

var d0e13 = new YAHOO.widget.TextNode(objd0e13, root, false);

 

sections etc. should get the ID of parent element instead.

 

 

My stylesheet is based on Eclipse stylesheet:

Any ideas are very appreciated.
