Subject: Re: [docbook-apps] webhelp javascript error
I believe this is a bug. I was able to re-produce the error with the docbook sample you have provided. We have introduced following code segment [1] to main.js in order to fix an issue with the page-scroll-down when clicking on url anchors (the urls with #).The culprit is the jquery function, $('[name=' + this.hash.slice(1) +']'). In your case, this.hash.slice(1) return section4.id, but jquery fails to process it.One option you can do is to get rid of this code, and implement the alternative as suggested in [2].[1]// When you click on a link to an anchor, scroll down// 105 px to cope with the fact that the banner// hides the top 95px or so of the page.// This code deals with the problem when// you click on a link within a page.$('a[href*=#]').click(function() {if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')&& location.hostname == this.hostname) {var $target = $(this.hash);$target = $target.length && $target|| $('[name=' + this.hash.slice(1) +']');if (!(this.hash == "#searchDiv" || this.hash == "#treeDiv" || this.hash == "") && $target.length) {var targetOffset = $target.offset().top - 120;$('html,body').animate({scrollTop: targetOffset}, 200);return false;}}});--On Wed, Mar 19, 2014 at 11:00 AM, natk <nkershaw@gmail.com> wrote:
I have encountered the following _javascript_ error in webhelp:Uncaught Error: Syntax error, unrecognized _expression_: [name=section4.id]
This only happens when I have a section which is four levels deep or more and I have given the section a manually generated id (i.e. it is a section to which I want to refer via an xref) which contains a dot(.) character.The error occurs when I click on the section in question in the navigation sidebar.My browser reports that the problem is in:
jquery-1.7.2.min.js:3This is a docbook sample which demonstrates the problem:<?xml version="1.0"?><book id="DocId" xmlns="http://docbook.org/ns/docbook"><title>Document Title</title><chapter><title>Chapter</title><section><title>Section Level 1</title><section><title>Section Level 2</title><section><title>Section Level 3</title><section><title>Section Level 4</title></section></section></section><section id="section2.id"><title>Section Level 2 with ID</title><section id="section3.id"><title>Section Level 3 with ID</title><section id="section4.id"><title>Section Level 4 with ID</title><para>And finally some text.</para></section></section></section><section id="section2id"><title>Section Level 2 with ID (no dot)</title><section id="section3id"><title>Section Level 3 with ID (no dot)</title><section id="section4id"><title>Section Level 4 with ID (no dot)</title><para>And some more text.</para></section></section></section></section></chapter></book>It doesn't seem to like manually generated 'id's with the dot character in them.Has anyone else found this? Is this a limitation of this format? Are there any other characters which are not permitted? Is it confusing the string literal for a regexp?Nat
