var index = getActiveSectionIndex();

WTF?! Did you know something about programming in JavaScript or other languages? getActiveSectionIndex() is a method of SectionChanger so put the fuckin reference in front of the method. Read just the fuckin API Reference and you will find in some seconds your mistake.

Just this code will do,

var index = sectionChanger.getActiveSectionIndex();
console.log("index : " + index);

this code doesn't work too..

Marco Buettner

It will if you know something about scopes in JavaScript ;)

But are you look some retarded, this code will work if not... you are have to do some basically tutorials about JavaScript...

 

app.js

var element = document.getElementById("sectionchanger"),
	page = document.getElementById("hasSectionchangerPage"),
	sectionChanger,
	activeSectionIndex;

page.addEventListener("pageshow", function() {
	sectionChanger = tau.widget.SectionChanger(element, {
		circular: true,
		orientation: "horizontal",
		useBouncingEffect: true
	});

	activeSectionIndex = sectionChanger.getActiveSectionIndex();
	console.log(activeSectionIndex);
});

page.addEventListener("pagehide", function() {
	sectionChanger.destroy();
});

index.html

<div id="hasSectionchangerPage" class="ui-page">
	<header class="ui-header">
		<h2 class="ui-title">SectionChanger</h2>
	</header>

	<div class="ui-section-changer" id="sectionchanger">
		<div>
			<section>
				<h3>LEFT1 PAGE</h3>
			</section>

			<section class="ui-section-active">
				<h3>MAIN PAGE</h3>
			</section>

			<section>
				<h3>RIGHT1 PAGE</h3>
			</section>
		</div>
	</div>
</div>

I solve this problem

    element.addEventListener("sectionchange", function() 
    {
        sectionChanger = tau.widget.SectionChanger(element);
        var index = sectionChanger.getActiveSectionIndex();
        console.log("index : " + index);
    });
