collapsing section and scrolling back to top

I am working on a long one-pager. Yes, I know, we hate one-pagers. At least I promise not to implement any parallax-effect, I promise :)
I have multiple sections I can open/close. This part works fine.
The problem: those sections get pretty long, and when they are being closed/collapsed, the user find himself somewhere in the middle of the one-pager.
So, when collapsing a section, I want it to collapse AND to smooth scroll back to the top/the start of the collapsed section.
Here my script:
// Section-Collapse
//---------------------------------------------------------
$("section a.read-more").click(function() {
if($(this).parents("section").hasClass("expanded")) {
var scrollAnchor = $(this).attr("data-scroll"),
scrollPoint = $(".anchor[data-anchor='" + scrollAnchor + "']").offset().top - 0;
$("body,html").animate({
scrollTop: scrollPoint
}, 1500, function() {
// close/collapse section
$(this).parents("section").addClass("close");
$("section.expanded.close div.expandable-content").slideUp();
$(this).parents("section").removeClass("expanded").removeClass("close");
alert("this test-message is being displayed");
});
} else {
// open section
$(this).parents("section").addClass("expanded");
$("section.expanded div.expandable-content").slideDown();
}
});
The problem: this part is not being executed EXCEPT the alert message, that one works. Although it is trying to open the dialog window multiple times and Firefox offers me to block this behavior.
// einklappen
$(this).parents("section").addClass("close");
$("section.expanded.close div.expandable-content").slideUp();
$(this).parents("section").removeClass("expanded").removeClass("close");
alert("this test-message is being displayed");
It scrolls back to top, to the anchor, but the section will not collapse...
Any ideas why it won't collapse?
Regards,
Milan
---------------------------UPDATE
So, it was a problem with the scope of variable "this".
This code here seems to work fine:
// Section-Collapse
//---------------------------------------------------------
$("section a.read-more").click(function() {
if($(this).parents("section").hasClass("expanded")) {
var scrollAnchor = $(this).attr("data-scroll"),
scrollPoint = $(".anchor[data-anchor='" + scrollAnchor + "']").offset().top - 0;
var global_this = $(this);
$("body,html").animate({
scrollTop: scrollPoint
}, 1500, function() {
// einklappen
global_this.parents("section").addClass("close");
$("section.expanded.close div.expandable-content").slideUp();
global_this.parents("section").removeClass("expanded").removeClass("close");
alert("this test-message is being displayed");
});
// return false;
} else {
// ausklappen
$(this).parents("section").addClass("expanded");
$("section.expanded div.expandable-content").slideDown();
}
});
What is bothering me: why this script tries to open multiple alert dialogs?

Accordion Functionality

I've put together an accordion script that works quite nicely (haven't cross-browser tested) and allows for lots of content inside each drawer to be accessed and visible on screen. A lot of times accordions open and cause issues with positioning after opening. Anyway, the code I'm using has a toggle active function and a scroll function being called on click.
function toggleActive(link){ // Set anchor to active
if ( $(link).hasClass("active") ) {
$(link).removeClass("active");
} else {
$(link).addClass("active");
};
};
function scrollToElement(selector, time, verticalOffset) { // param 1 = id, param 2 = speed
time = typeof(time) != 'undefined' ? time : 1000;
verticalOffset = typeof(verticalOffset) != 'undefined' ? verticalOffset : 0;
element = $(selector);
offset = element.offset();
offsetTop = offset.top + verticalOffset;
$('html, body').animate({scrollTop: offsetTop }, time);
}
$('#accordion a').click(function(e) {
var link = '#' + event.target.id
$(".tab-content").slideUp();
$(".tab").removeClass("active");
toggleActive(link);
$(link).next().slideToggle("fast");
setTimeout(function() {
scrollToElement($(link), 500);
}, 500);
e.preventDefault();
});
So when clicked, all of the tabs are closed and made inactive, then the targeted "drawer" is opened and made active. If for any reason you click an already "active" drawer, it runs through the script again. What I'd like to do is place an IF statement that determines if what you just clicked is already open, and then simply close that drawer. Thanks in advance. I don't know why this is causing me headaches.
JSFiddle

As I understand you need another function as below:
function isAlreadyActive(link)
{
if ( $(link).hasClass("active") ) {
$(link).removeClass("active");
return true;
} else {
return false;
};
}
And you should call that function in your click event. This function will check if the link already active, if so just deactivates it and changes as you want.
$('#accordion a').click(function(e) {
var link = '#' + event.target.id
/* if it is already active, just deactivate it and exit*/
if(isAlreadyActive(link)){
return false;
}
$(".tab-content").slideUp();
$(".tab").removeClass("active");
toggleActive(link);
$(link).next().slideToggle("fast");
setTimeout(function() {
scrollToElement($(link), 500);
}, 500);
e.preventDefault();
});
I hope this helps.

Trying to get my slideshow plugin to infinitely loop (by going back to the first state)

I wrote a slideshow plugin, but for some reason maybe because I've been working on it all day, I can't figure out exactly how to get it to go back to state one, once it's reached the very last state when it's on auto mode.
I'm thinking it's an architectual issue at this point, because basically I'm attaching the amount to scroll left to (negatively) for each panel (a panel contains 4 images which is what is currently shown to the user). The first tab should get: 0, the second 680, the third, 1360, etc. This is just done by calculating the width of the 4 images plus the padding.
I have it on a setTimeout(function(){}) currently to automatically move it which works pretty well (unless you also click tabs, but that's another issue). I just want to make it so when it's at the last state (numTabs - 1), to animate and move its state back to the first one.
Code:
(function($) {
var methods = {
init: function(options) {
var settings = $.extend({
'speed': '1000',
'interval': '1000',
'auto': 'on'
}, options);
return this.each(function() {
var $wrapper = $(this);
var $sliderContainer = $wrapper.find('.js-slider-container');
$sliderContainer.hide().fadeIn();
var $tabs = $wrapper.find('.js-slider-tabs li a');
var numTabs = $tabs.size();
var innerWidth = $wrapper.find('.js-slider-container').width();
var $elements = $wrapper.find('.js-slider-container a');
var $firstElement = $elements.first();
var containerHeight = $firstElement.height();
$sliderContainer.height(containerHeight);
// Loop through each list element in `.js-slider-tabs` and add the
// distance to move for each "panel". A panel in this example is 4 images
$tabs.each(function(i) {
// Set amount to scroll for each tab
if (i === 1) {
$(this).attr('data-to-move', innerWidth + 20); // 20 is the padding between elements
} else {
$(this).attr('data-to-move', innerWidth * (i) + (i * 20));
}
});
// If they hovered on the panel, add paused to the data attribute
$('.js-slider-container').hover(function() {
$sliderContainer.attr('data-paused', true);
}, function() {
$sliderContainer.attr('data-paused', false);
});
// Start the auto slide
if (settings.auto === 'on') {
methods.auto($tabs, settings, $sliderContainer);
}
$tabs.click(function() {
var $tab = $(this);
var $panelNum = $(this).attr('data-slider-panel');
var $amountToMove = $(this).attr('data-to-move');
// Remove the active class of the `li` if it contains it
$tabs.each(function() {
var $tab = $(this);
if ($tab.parent().hasClass('active')) {
$tab.parent().removeClass('active');
}
});
// Add active state to current tab
$tab.parent().addClass('active');
// Animate to panel position
methods.animate($amountToMove, settings);
return false;
});
});
},
auto: function($tabs, settings, $sliderContainer) {
$tabs.each(function(i) {
var $amountToMove = $(this).attr('data-to-move');
setTimeout(function() {
methods.animate($amountToMove, settings, i, $sliderContainer);
}, i * settings.interval);
});
},
animate: function($amountToMove, settings, i, $sliderContainer) {
// Animate
$('.js-slider-tabs li').eq(i - 1).removeClass('active');
$('.js-slider-tabs li').eq(i).addClass('active');
$('#js-to-move').animate({
'left': -$amountToMove
}, settings.speed, 'linear', function() {});
}
};
$.fn.slider = function(method) {
if (methods[method]) {
return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));
} else if (typeof method === 'object' || !method) {
return methods.init.apply(this, arguments);
} else {
return false;
}
};
})(jQuery);
$(window).ready(function() {
$('.js-slider').slider({
'speed': '10000',
'interval': '10000',
'auto': 'on'
});
});​
The auto and animate methods are where the magic happens. The parameters speed is how fast it's animated and interval is how often, currently set at 10 seconds.
Can anyone help me figure out how to get this to "infinitely loop", if you will?
Here is a JSFiddle

It would probably be better to let go of the .each() and setTimeout() combo and use just setInterval() instead. Using .each() naturally limits your loop to the length of your collection, so it's better to use a looping mechanism that's not, and that you can break at any point you choose.
Besides, you can readily identify the current visible element by just checking for .active, from what I can see.
You'd probably need something like this:
setInterval(function () {
// do this check here.
// it saves you a function call and having to pass in $sliderContainer
if ($sliderContainer.attr('data-paused') === 'true') { return; }
// you really need to just pass in the settings object.
// the current element you can identify (as mentioned),
// and $amountToMove is derivable from that.
methods.animate(settings);
}, i * settings.interval);
// ...
// cache your slider tabs outside of the function
// and just form a closure on that to speed up your manips
var slidertabs = $('.js-slider-tabs');
animate : function (settings) {
// identify the current tab
var current = slidertabs.find('li.active'),
// and then do some magic to determine the next element in the loop
next = current.next().length >= 0 ?
current.next() :
slidertabs.find('li:eq(0)')
;
current.removeClass('active');
next.addClass('active');
// do your stuff
};
The code is not optimized, but I hope you see where I'm getting at here.

How to stop sliding if only one <li> using anythingSlider(jQuery plugin)?

I'm currently using the anythingSlider plugin, it works totally fine except when there is only one <li>.
The <li>s are generated from the database so sometimes there's only one.
However, the anythingSlider plugin still tries to slide through the <li>s, it works by sliding back to the first slide. Although this doesn't look great.
Does anybody know of a way of stopping it sliding if there's only one <li>?
-- EDIT --
Hi!
Can anybody else help with this? I've tried the solution by Greg and I've also tried:
if (banners<1) {
.anythingSlider({
startStopped: true,
buildNavigation: false
});
}
'banners' is my variable that I'm calling.
And this disables the anythingSlider function altogether.
Help please?!

index = integer index (1 based);
panel = jQuery wrapped LI item this tab references
#return = Must return a string of HTML/Text

});

Changing this
$('.anythingSlider').anythingSlider({...});
to this
$('.anythingSlider:has(li:nth-child(2)').anythingSlider({...});
should do it
This assumes you don't have nested lists.

I had this problem and could only resolve this with a new version of the plugin: v1.5.3
URL: https://github.com/ProLoser/AnythingSlider/downloads
Once you've got the latest version, only change one line:
base.setCurrentPage(startPanel, false); // added to trigger events for FX code
When I have only one <li> the anythingControls element's style is display=none.

This will only activate the slider if more than 1 <LI> elements are present:
jQuery("#sliderDiv:has(>li:eq(1))").anythingSlider({...})
it assumes your HTML structure is like this:
<div id="sliderDiv">
<li>Offer 1</li>
<li>Offer 2</li>
</div>

You'll need something like
if($([ULELEMENT]).children('li').length > 1){
//Your code
}
Something along those lines. If you post your code, I can give it a try.

longtail player + anythingslider + event listeners

I've implemented the AnythingSlider (http://css-tricks.com/anythingslider-jquery-plugin/) using image and video content (videos use the longtail flv player - licensed version 5).
Problem: When the user plays the video, the slideshow doesn't know this has happened, so the slideshow keeps cycling while the video runs. So you have the slideshow running - and user can hear the audio but the video has cycled off.
UPDATE - here is a link to see what's going on: http://silverberry.org/beta/slider-longtail/
I'm trying to figure out an event-listener that will look and see when the LONGTAIL player is in PLAYING state and signals to the AnythingSlider that it needs to STOP.
Here's what I've got so far ... the video player event listeners are working (right now I have alerts popping up so that I can be sure the events are being heard). An alert pops up with the player is initialized .. and alert pops up when we press the PLAY button on the video ... and an alert pops up when the video STOPS playing. But ... I've yet to work out the proper syntax for signaling to the anythingslider to STOP!
I thought it would be this:
$VUslider.startStop(false);
Below is the code I have so far ... beginning with the code that initializes the slider.
function formatText(index, panel) {
return index + "";
}
$(function () {
$('.VUslider').VUslider({
autoPlay: true,
delay: 7000,
startStopped: false,
animationTime: 200,
hashTags: true,
buildNavigation: false,
pauseOnHover: true,
navigationFormatter: formatText
});
});
var player = null;
function playerReadyCallback(obj) {
player = document.getElementsByName(obj.id)[0];
alert('the videoplayer '+obj['id']+' has been instantiated');
player.addModelListener('STATE', 'stateMonitor');
}
function stateMonitor(obj) {
currentState = obj['newstate'];
if(currentState == 'PLAYING') {
alert ('the videoplayer '+obj['id']+' is playing now!');
$VUslider.startStop(false); // Trigger slideshow stop
}
if(obj.newstate == 'COMPLETED') {
alert ('the videoplayer '+obj['id']+' has stopped playing now!');
$VUslider.startStop(true); // Trigger slideshow start
}
}
FOR REFERENCE ... HERE IS THE ANYTHING SLIDER CODE:

$.VUslider = function(el, options){

// to reference this class from internal events and functions.

Are you setting $VUslider to equal $('.VUslider').VUslider({ . . }); ?
In your example code you are not.
You should be doing something like this:
$VUslider = $('.VUslider').VUslider({
autoPlay: true,
delay: 7000,
startStopped: false,
animationTime: 200,
hashTags: true,
buildNavigation: false,
pauseOnHover: true,
navigationFormatter: formatText
});

This is somewhat of a stab in the dark, so I'll try to explain my reasoning a bit.
After you've created the VUslider bits as you're already doing, try doing this to start/stop the slider:
$('.VUslider').VUslider.startStop(false);
// this will toggle between starting and stopping but doesn't give control
// to call start or stop specifically.
$('#start-stop').click();
When you call $('.VUslider').VUslider({...}), it doesn't return anything, so there's no handle to VUslider at that point ($.each(..) doesn't return anything). This will hopefully get you a reference to the script and to the startStop function.
