multiple instances of fullpage.js - javascript

I am trying to use fullpage.js for two different sections on one website. Basically, when a slide is clicked on, it reveals a child wrapper div underneath with its own sections to vertically scroll through before the main section continues on.
Here is my code that I am working with. I'm trying to load it in through ajax but I'm wondering if there is an easier way I am overlooking.
$("#wrapper").fullpage({
verticalCentered: true,
resize : true,
anchors: ['section1', 'section2', 'section3', 'about'],
//menu:'#menu',
customScroll:true,
onLeave: function(index, nextIndex, direction){
//console.log(index+'|'+nextIndex+'|'+direction);
if (direction == 'down'){
$('.section:nth-child('+index+')').animate({'top':'0%'},0)
$('.section:nth-child('+nextIndex+')').animate({'top':'100%'},0).animate({'top':'0%'},500);
} else {
$('.section:nth-child('+nextIndex+')').animate({'top':'0%'},0);
$('.section:nth-child('+index+')').animate({'top':'0%'},0).animate({'top':'100%'},500).animate({'top':'500%'},0);
}
}
});
and then the code that removes it and adds a new wrapper:
$(".sub_section").click(function() {
$("#wrapper").fullpage.destroy('all');
if (sub_section_open == false) {
$("#left_border").animate({"borderLeftWidth" : "0px"}, 300);
$("#right_border").animate({"borderRightWidth" : "0px"}, 300);
$("#top_border").animate({"borderTopWidth" : "0px"}, 300, function() {
$("#left_border").hide();
$("#right_border").hide();
$("#top_border").hide();
});
$(".sub_section .letters").slideUp("slow", function(){
$(".sub_section .content").css({'z-index': 1});
});
sub_section_open = true;
$(".btn_sub_section_close").show();
$( "#wrapper" ).load( "section1.html" );
$("#section1").fullpage({
verticalCentered: true,
resize : true,
anchors: ['ssection1', 'ssection2', 'ssection3', 'ssection4'],
menu:'#menu'
});
}
});
Any ideas? Thanks!

fullpage.js only supports one instance.
It is a fullpage plugin and it is not made to support them as it doesn't make sense. It is full page, all the page will be part of one instance of fullpage.
You can easily see evidences of it in the code, for example in this line:
$('.fp-section').each(function(index){
Any section on the page, no matter which container/wrapper it uses, will be treated inside one single instance of fullpage.

On GitHub, Fullpage.js has labeled the issue as enhancement. So there is a chance we get the multiple instances option in a future version :)

Fullpage.js with GSAP - Callback afterLoad animation

I am trying to add some animations to fullpage.js with GSAP and have a question regarding the afterLoad function. Here's my code (with codepen link included)
$("#wrapper").fullpage({
verticalCentered:true,
scrollingSpeed: 1000,
sectionSelector: "section",
afterLoad: function(anchorLink, index) {
var loadedSection = $(this);
if (index == 2) {
TweenMax.from(".second h1", 1, {opacity:0, left:"-20px"});
}
}
});
What I would like to do is, use the afterLoad function to animate (fadeIn / slideIn) elements of the current section. My codepen link is here.
I am able to do this successfully (pls see the second section of the pen, you'll see it fades in), but the problem is it doesn't start with the animation. It has a delay before the animation starts, so during that delay, the elements need to be hidden (Not sure how to do this, I tried visibility:hidden to start with, it didn't work).
I am able to achieve the same thing with onLeave (but from 2nd section onwards).
Looking forward! Cheers!
UPDATE
I managed to figure it out. Thanks for Alvaro for chipping in a prompt reply. Here's the updated code:
$("#wrapper").fullpage({
verticalCentered:true,
scrollingSpeed: 1000,
sectionSelector: "section",
afterLoad: function(anchorLink, index) {
var loadedSection = $(this);
if (index == 1) {
$(".second h1").hide();
}
if (index == 2) {
$(".second h1").show();
TweenMax.from(".second h1", 1, {opacity:0, left:"-20px", delay:0.5});
}
}
});

Tweaking hover area for jQuery sliding boxes

I'm using some jQuery to create 3 boxes that on hover, slide up to reveal more content. My two questions are:
1) How can I tweak it so only hovering on the gray box actually activates the slide instead of the entire invisible area above the gray box?
2) Is there a better way to accomplish this? I'm a beginner when it comes to JavaScript and hacked a few things I found in Google searches together. For example, it'd be nice for the height to be generated automatically based on the content instead of relying on a fixed height.
http://jsfiddle.net/kUjax/
$(document).ready(function(){
$('.boxgrid.caption').hover(function(){
$(".cover", this).stop().animate({top:'120px'},{queue:false,duration:150});
}, function() {
$(".cover", this).stop().animate({top:'210px'},{queue:false,duration:150});
});
});
You almost did it yourself:
$(document).ready(function () {
$('.boxgrid .boxcaption').hover(function () {
$(this).stop().animate({top: '120px'}, {
queue: false,
duration: 150
});
}, function () {
$(this).stop().animate({top: '210px'}, {
queue: false,
duration: 150
});
});
});

Issue with jquery fadein

I have a piece of code here which it works but not sure why my fadein and fadeout doesn't work for the body,
If you think what the issue i'm having please let me know thanks
<script type="text/javascript">
$(window).load(function() {
var lastSlide = "";
$('#slider').nivoSlider({
effect: 'random',
directionNavHide : true,
slices : 15,
animSpeed : 500,
pauseTime : 6000,
controlNav : false,
pauseOnHover : true,
directionNav:true, //Next & Prev
directionNavHide:true, //Only show on hover
beforeChange: function(){
if(lastSlide == "images/header_used.jpg") { //use the bg image of the slide that comes before the newslide
$("body").attr("style","background: #000 url(images/bg.jpg) top center no-repeat;").fadeIn("slow");
} else {
$("body").attr("style","background: #ADADAD url(images/bgnd_grad.jpg) repeat-x;").fadeOut("slow");
}
},
afterChange: function() {
t = $(this).children("a:visible");
lastSlide = $("img", t).attr("src");
}
});
});
</script>
While it may solve your mission with the body background. i would instead have used addClass and removeClass. You are manipulating the style attribute which also show/hide uses it.
I have no way to test it but what happens if you switch the fades to show() and hide(), just to determine if delay is a factor.. :)
It my come by the fact that "lastSlide" variable could store multiple object (the one from img and the one from visible link).
t = $(this).children("a:visible");
lastSlide = $("img", t).attr("src"); //could store multiple source.
This make comparation a little bit tricker and could create bug.
Plus the fact that you use the worst way to style your body. As other says, use class or .css jQuery function (http://api.jquery.com/css/).
Hope this help
fadein and fadeout work for body,absolutely.
as Reflective said, it should be
$("body").css("background","#000 url(images/bg.jpg) top center no-repeat;").fadeOut("slow")
if still doesn't work, you may should look into your nivoSlider function

Mouseover event handler brings up both divs when I want only one

I am trying to do a mouseover event for one picture where when you mouseover a div comes up and animates on the picture. When I do my mouseover though, it brings up both divs for separate pictures when I only want one at a time. Here is my code. The first part is the mouseover. Second is mouseout.
$('.portfolio img').mouseover(function(){
$(this).css('cursor', 'pointer');
$(this).parent().find('img:first').stop().animate({opacity:1}, 800, function() {
$("div.folio").animate({ height: '+=25px', top: '-=24px' }, 100, function() {
$("div.folio span").animate({ opacity: 1 }, 500);
});
});
});
$('.img_grayscale').mouseout(function(){
$(this).stop().animate({opacity:0}, 800, function() {
$("div.folio span").animate({ opacity: 0 }, 500, function() {
$("div.folio").animate({ height: '-=25px', top: '+=24px' }, 100);
$("div.folio").css('top', '-9px');
});
});
});
<div class="portfolio">
<h2>The Portfolio</h2>
<p class="slideTwo">Check out some of our recent projects.</p>
<ul>
<li><img src="portfolioOne.jpg"></img><div class="folio"><span>thesite.com</span></div></li>
<li><img src="portfolioOne.jpg"></img><div class="folio"><span>mysite.com</span></div></li>
</ul>
</div>
Using jQuery's $("div.folio") will return all divs with a class of "folio". Since you are seeing this animation on both images, rather than just the one you've moused-over, I'm assuming they both have the same class on the div they want to animate. In order to only animate one, you'll need to be more specific when selecting it with jQuery. Including $(this) on the path to the div to animate usually works, but I can't tell you the exact code without the corresponding HTML.
You need to cancel the bubble up event by returning "false" from your event handler.
$('.portfolio img').mouseover(function(){
// Your logic here...
return false;
});
There are a couple of concerns that I have about this which may or may not be problematic depending on what else is going on that you haven't shown.
You're doing $(this).parent().find('img:first') inside of a jQuery onmouseover function where $(this) should already be representing the img that you care about. Did you find that was necessary for some reason?
You could be more specific in your selector. Try doing $(".portfolio>ul>li>img")
img_grayscale is only mentioned once in your markup in your question so I'm not sure how that class gets applied but I'm assuming it does.
You could just add the class portfolio (or some unique identifier) to your images directly and probably have an easier time figuring out exactly why it isn't working as you expect. Then your mouseover selector could just be $(".specialClass")
You should definitely try posting a jsfiddle.net; you could borrow any two images off the web for testing.
Managed to figure this one out. I had to basically transverse the DOM through the following code. I referenced the image and then I went to the parent then to the next element in the DOM which was my div of div.folio. Then I went to the child of that object to fade it in. I did the same thing in reverse basically on the mouseout.
$('.portfolio img').mouseover(function(){
$(this).css('cursor', 'pointer');
$(this).parent().find('img:first').stop().animate({opacity:1}, 800, function() {
$(this).parent().next().animate({ height: '+=25px' }, 100, function() {
$(this).children().animate({ opacity: 1 }, 100);
});
});
});
$('.img_grayscale').mouseout(function(){
$(this).stop().animate({opacity:0}, 800, function() {
$(this).parent().next().children().animate({ opacity: 0 }, 100, function() {
$(this).parent().animate({height: '-=25px' }, 100);
});
});
});

Todays Special: How is this done? Is there a jquery plugin or product to do it?

I saw this technique at the bottom of a web page where the TAB stays in place at the bottom of the page and can be opened and closed to display more info. I assume it can be rotated to display a different special for different days. Can you point me to anything like it or explain the technique ? thanks. Here is a sample: http://www.tmdhosting.com/ look at the bottom of the page .
position: fixed is how you manage to keep something at the bottom or top of the page, regardless of scrolling.
This is easily discoverable using firebug's (http://getfirebug.com/) inspect element feature

I wrote a jQuery plugin to do it, and calling it is straightforward:
$('#about').pulloutPanel({open:true}).
click(function() { $(this).trigger('toggle'); }) });
I basically instrument the panel to support "open", "close" events, and the implement the appropriate animations around them. The only "hard" part is getting the height right. It also supports "toggle" so you can add a generic click handler to it to open or close it. Finally, it uses opened/closed classes to keep track of its current state. That's it!
The code's pretty coupled to the technologies on the page (Csster) and the design it is in, so I'm not sure it will work for you. You can either use Csster, or just put the CSS rules into your stylesheet and remove them from the code. The important Css attributes are the positioning and bottom.
Here it is:
$.fn.pulloutPanel = function(options) {
var settings = $.extend({}, {
attachTo: 'bottom',
css: {
left: 0,
minHeight: 390,
border: '1px 1px 1px 0 solid #666',
has: [roundedCorners('tr', 10),boxShadow([0,0], 10, phaseToColor('requirements').saturate(-30).darken(50))],
cursor: 'pointer'
}, options);
return $(this).each(function() {
var $this = $(this);
$this.addClass('pullout_panel');
$this.bind('open', function(event) {
$this.animate({bottom: 0}, 'slow', 'easeOutBounce', function() {
$this.removeClass('closed').addClass('opened');
$this.trigger('opened');
});
});
$this.bind('close', function(event) {
var height = $this.innerHeight();
$this.animate({bottom: -height + 50}, 'slow', 'easeOutBounce', function() {
$this.addClass('closed').removeClass('opened');
$this.trigger('closed');
});
});
$this.bind('toggle', function(event) {
$this.trigger($this.hasClass('opened') ? 'close' : 'open');
});
once(function() {
Csster.style({
'.pullout_panel': {
position: 'fixed',
bottom: 0,
has: [settings.css]
}
});
});
$this.trigger(settings.open ? 'open' : 'close');
});
};
