I made it in a very strange way... here is the demo with TOC highlight
http://uvakin.neocities.org/heeg.html
I put some code zoomin.js
/*
Find the first child DOM node of a widget that has the class "tc-title"
*/
function parentTag(node) {
return node.parentNode;
}
function findTitleDomNode(widget,targetClass) {
targetClass = targetClass || "tc-title";
var domNode = widget.findFirstDomNode();
if(domNode.querySelector('.tc-title') != null ){
var ttitle=domNode.querySelector('.tc-title').textContent.replace(
/^\s+|\s+$/mg,'');
document.title=ttitle;
var elements = document.querySelectorAll('ol a,ol ol a,ol button,ol ol
button') ;
for (var i = 0; i < elements.length; i++) {
elements[i].style.color = 'inherit';
parentTag(elements[i]).style.backgroundColor = '';
parentTag(parentTag(elements[i])).style.backgroundColor = '';
if( elements[i].textContent.replace(/^\s+|\s+$/mg,'')==ttitle){elements[i].
style.color = '#ff8400';
if(
parentTag(elements[i]).tagName=="LI"){parentTag(elements[i]).style.backgroundColor
= 'rgba(0, 0, 0, 0.1)';} ;
if( parentTag(parentTag(elements[i])).tagName=="LI"){parentTag(parentTag
(elements[i])).style.backgroundColor = 'rgba(0, 0, 0, 0.1)';} ;
} ;
}
}
if(domNode && domNode.querySelector) {
return domNode.querySelector("." + targetClass);
}
return null;
}
