Cannot override data-aplay data attribute in jQuery on hover event

I am trying to disable the autoscroll function in my slider on hover, and similarly when I move the mouse away, begin the slider once again. The data attribute isn't getting updated. Even though it's showing in console.
HTML code:
<div id="featured" class="swiper-container gloria-sliders events-list-carousel swiper-container-horizontal swiper-container-undefined" data-item="3" data-column-space="1" data-sloop="true" data-aplay="4000">
As you can see, it is setting the data attribute data-aplay to 4000 by default.
Attaching script below:
<script>
$("#featured").hover( function () {
console.log('hover');
var featured = $('#featured').data('aplay','false');
console.log($('#featured').data('aplay'));
}, function() {
console.log('not hovered');
$('#featured').data('aplay','4000');
console.log($('#featured').data('aplay'));
});
</script>
When I hover, it displays:
hover
false
But it doesn't update the data-aplay value, also when I remove the hover it displays
not hovered
4000
If any additional info is required, please let me know. Any help will be greatly appreciated. Thank You
UPDATE
var stopScroll = setInterval(function(){ $(".metalhead").click(); }, 4000) ;
$('.oswald, .image a').click(function() {
clearInterval(stopScroll);
});
$('#featured').mouseover(function(){
clearInterval(stopScroll);
}).mouseout(function(){
stopScroll = setInterval(function(){ $(".metalhead").click(); }, 4000) ;
})
I am using setInterval and clearInterval now. It is working to some extent. But still not accurate
<i class="fa fa-angle-right metalhead" id="scroll" aria-hidden="true"></i>
So what I am doing now is adding a function to click on the right arrow every 4 seconds. So on mouseover I am using clearInterval to remove the timer and on mouseout using setInterval to revert back to 4 seconds.
I have also added another function, which stops the slider when a particular item is clicked. Still not confident it is working correctly though.

I do believe it is changing the data property properly, only that does not update the view of the attribute, try something like this:
$(document).ready(function() {
var featured=$('#featured');
featured.hover( function () {
console.log('hover');
featured.data('aplay','false');
featured.removeAttr('data-aplay')
console.log(featured.data('aplay'));
}, function() {
console.log('not hovered');
featured.attr('data-aplay', '4000')
featured.data('aplay','4000');
console.log(featured.data('aplay'));
});
});

Loop through element and change based on link attribute

Trying to figure this out. I am inexperienced at jQuery, and not understanding how to loop through elements and match one.
I have 3 divs:
<div class="first-image">
<img src="images/first.png">
</div>
<div class="second-image">
<img src="images/second.png">
</div>
<div class="third-image">
<img src="images/third.png">
</div>
And off to the side, links in a div named 'copy' with rel = first-image, etc.:
...
Clicking the link will fade up the image in the associated div (using GSAP TweenMax)
Here is the function I've been working on to do this... but I am not fully understanding how to loop through all the "rel" elements, and make a match to the one that has been clicked on.
<script>
//pause slideshow on members to ledger when text is clicked, and show associated image
$(function() {
$('.copy').on('click','a',function(e) {
e.preventDefault();
var slideName = $(this).attr('rel');
$("rel").each(function(i){
if (this.rel == slideName) {
console.log(this);
}
});
//var change_screens_tween = TweenMax.to('.'+slideName+'', 1, {
//autoAlpha:1
//});
});
});
</script>
What am I doing wrong? I don't even get an error in my browser. :-(
Thanks to the answer below, I got farther. Here is my revised code.
$('[rel]').each(function(k, v){
if (v == slideName) {
var change_screens_tween = TweenMax.to('.'+slideName+'', 1, {
autoAlpha:1
});
} else {
var change_screens_tween = TweenMax.to('.'+slideName+'', 1, {
autoAlpha:0
});
}
});
});
This is starting to work, but makes the screenshots appear and then instantly fade out. And it only works once. Any thoughts?

Add brackets around rel, like so:
$('[rel]').each(function() {
if ($(this).attr('rel') == slideName) {
console.log(this);
}
});

How write this in javascript

I have problems for insert dynamic id into function of JavaScript the code:
$('#scroll-up1, #scroll-down1').bind({ ..............
In this example I need the function to take values of id I send across the function
$('#scroll-up+id, #scroll-down+id').bind({ ..............
The problem it´s the quotes as " or ' no works for me and I can´t use right for function works fine , this script let me scroll text ok but only problem with this because no let me send values right from id of function.
EDIT FOR ME FOR PUT ALL CODE : .....
PHP AND HTML CODE
<?php
$fil_comments=file("comments.txt");
for ($i=0;$i<sizeof($fil_comments);$i++)
{
$line=explode("~",$fil_comments[$i]);
if ($i%2==0)
{
$back=1;
}
else
{
$back=2;
}
?>
<li>
<div id="web_comment_<?php echo $back?>">
<div id="web_comment_name"><?php echo $line[0];?></div>
<div class="web_comment_texto" id="scroll<?php echo $i;?>"><?php echo $line[1];?></div>
<div class="web_comment_arrow" style="margin-left:260px;" id="scroll-down<?php echo $i;?>"><img src="imagenes/comments/arrow_up.png"></div>
<div class="web_comment_arrow" style="margin-left:288px;" id="scroll-up<?php echo $i;?>"><img src="imagenes/comments/arrow_down.png"></div>
</div>
</li>
<script>
scroll_diver(<?php echo $i;?>);
</script>
<?
}
?>
FUNCTION OF JAVASCRIPT CODE
<script type="text/javascript">
function scroll_diver(id)
{
$(function() {
var ele = $('#scroll'+id);
var speed = 30, scroll = 5, scrolling;
$('#scroll-up'+id).mouseenter(function() {
// Scroll the element up
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() - scroll );
}, speed);
});
$('#scroll-down'+id).mouseenter(function() {
// Scroll the element down
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() + scroll );
}, speed);
});
//var a='#scroll-up'+id;
//var b='#scroll-down'+id;
var a='#scroll-up'+id;
var b='#scroll-down'+id;
//$('a,b').bind({
//$('#scroll-up1, #scroll-down1').bind({
//$('#scroll-up'+id+',#scroll-down'+id)
/// THE PROBLEM HERE !!!
$('#scroll-up'+id+', #scroll-down '+id).bind({
click: function(e) {
// Prevent the default click action
e.preventDefault();
},
mouseleave: function() {
if (scrolling) {
window.clearInterval(scrolling);
scrolling = false;
}
}
});
});
}
</script>
Basically the problem it´s in the line of JavaScript function for send id, if you see the PHP code, I use bucle for for create scrolling tips with informations and in each I can scroll his content, for this I call function into the bucle with:
<script>
scroll_diver(<?php echo $i;?>);
</script>
But in this line no send right information for works ok, if I use out bucle for one specific id, works ok , with this works yes but scroll up and down crazy fast , and the controls no works fine.

Then you need to look at something like this:
$('#scroll-up' + id + ', #scroll-down' + id).bind({ ..............
As a commentor mentioned, jQuery selectors are simply strings. You can put them together as you see fit. In this case, I'm concatenating the id (which for simplest examples, I'm assuming is a number or other unique identifier) to the #scroll-up selector, so if your id was "1", you would end up with a string, effectively, that looks like:
'#scroll-up1, #scroll-down1'
after the string concatenation occurs.
Also, it might be worth noting that you'd probably get better bang for your buck if you simply gave both objects the same class, then inside your binding function, work out which item called and perform your scrolling appropriately.
So, if you had:
<div class="container">
<div id="scroll-up1" class="scroller"><!-- and code --></div>
<div id="scroll-down1" class="scroller"><!-- and code --></div>
</div>
then your javascript could look like this, avoiding the need for concatenation:
$('.container').on("mouseover",'.scroller', function(){
var thisId = $(this).attr("id");
if(thisId == "scroll-up1"){
// do your up-scroll
} else if(thisId == "scroll-down1") {
// do your down-scroll
}
});
Mind you, that uses .on(), which is preferred over .bind(), but the idea is to handle it based on a common class, rather than having to modify your selector every time you go to bind your event handler for those items.

Recommended solution: use CLASS NAMES for COMMON FEATURES
$('.scroll-up, .scroll-down').bind({
or even:
$('.scroll').bind({

var id = 38;
$('#scroll-up' + id + ', #scroll-down' + id).bind({ ..............

Create Fancybox gallery when integrated with PikaChoose [duplicate]

I'm using the Fancybox integration with Pikachoose as explained here:
http://www.pikachoose.com/how-to-fancybox/
I'm trying to get the lightbox to display next and previous arrows but not on the pikachoose stage and I'm having a bit of trouble. I tried to add the options of showNavArrows: true in the fancybox section of the script but it wouldn't work. So then I tried the nav options on pikachoose to display using this: {text: {previous: "Previous", next: "Next" }}
but I keep getting an error, possibly my syntax isn't going in the right place?
Can someone help please?
this is the code I'm using :
$(document).ready(function () {
var a = function (self) {
self.anchor.fancybox({
transitionIn: elastic,
transitionOut: elastic,
speedIn: 600,
speedOut: 200,
overlayShow: false
});
};
$("#pikame").PikaChoose({
showCaption: false,
buildFinished: a,
autoPlay: false,
transition: [0],
speed: 500,
showCaption: false
});
});

The problem with the method explained in http://www.pikachoose.com/how-to-fancybox/ is that you bind fancybox to the current pikachoose element self.anchor.
With that approach, there is no way to know what group of images will belong to a fancybox gallery (you would need more than one element sharing the same rel attribute) because there is just a single pikachoose image : every image is displayed toggling dynamically its href and src attributes (<a> and <img> tags respectively) inside the .pika-stage container.
As a workaround, you would need to built the fancybox group of elements BEFORE binding your html structure to pikachoose (pikachoose will modify the DOM structure)
1). So having this html structure :
<div class="pikachoose">
<ul id="pikame">
<li>
<a title="one" href="image01.jpg" id="single_1"><img alt="" src="thumb01.jpg" /></a>
</li>
<li>
<a title="two" href="image02.jpg" id="single_2"><img alt="" src="thumb02.jpg" /></a>
</li>
<li>
<a title="three" href="image03.jpg" id="single_3"><img alt="" src="thumb03.jpg" /></a>
</li>
</ul>
</div>
2). Create the fancybox group of elements iterating through each anchor with this script :
var fancyGallery = []; // fancybox gallery group
$(document).ready(function () {
$("#pikame").find("a").each(function(i){
// buidl fancybox gallery group
fancyGallery[i] = {"href" : this.href, "title" : this.title};
});
}); // ready
3). Then bind pikachoose to the same selector #pikame. You can use the .end() method to do it over the first decelerated selector without duplicating it ;)
var fancyGallery = []; // fancybox gallery group
$(document).ready(function () {
// build fancybox group
$("#pikame").find("a").each(function(i){
// buidl fancybox gallery
fancyGallery[i] = {"href" : this.href, "title" : this.title};
}).end().PikaChoose({
autoPlay : false, // optional
// bind fancybox to big images element after pikachoose is built
buildFinished: fancy
}); // PikaChoose
}); // ready
Notice that we used the pikachoose option buildFinished: fancy, which actually will fire the fancybox gallery when we click on the big image.
4). Here is the function :
var fancy = function (self) {
// bind click event to big image
self.anchor.on("click", function(e){
// find index of corresponding thumbnail
var pikaindex = $("#pikame").find("li.active").index();
// open fancybox gallery starting from corresponding index
$.fancybox(fancyGallery,{
// fancybox options
"cyclic": true, // optional for fancybox v1.3.4 ONLY, use "loop" for v2.x
"index": pikaindex // start with the corresponding thumb index
});
return false; // prevent default and stop propagation
}); // on click
}
Notice that we bound a click event using .on() (requires jQuery v1.7+) to the pikachoose element self.anchor to fire fancybox gallery using the manual method $.fancybox([group]).
This workaround works equally fine for fancybox v1.3.4 or v2.x. See DEMO using v1.3.4 that seems to work fine even with IE7 ;)

JFK response is great, but there is something to correct :
if carousel is enabled in Pikachoose, the computed index using this method will give you an invalid one, beacause pikachoose will manipulate DOM by appending existing li in ul:
var pikaindex = $("#pikame").find("li.active").index();
Solution :
function getCurrentIndex(fancyGallery) {
var activeLi = $(""#pikame").find("li.active");
if (activeLi.length != 1) {
console.error('(getCurrentIndex) - only one image must have an active class set by Pikachoose');
return -1;
}
var activeLiHtml0 = activeLi[0];
var activeHref = $(activeLiHtml0).find('img').attr('src'); // do not look for <a> tags, PikaChoose will remove them
if (activeHref === null || activeHref.length == 0) {
console.error('(getCurrentIndex) - can not get href attribute from selected image');
return -1;
}
for (var i=0 ; i<fancyGallery.length ;i++) {
var obj = fancyGallery[i];
if (obj.href.indexOf(activeHref) >= 0){
console.debug('(getCurrentIndex) - found index: ' + i);
return i;
}
}
console.error('(getCurrentIndex) - this href: <' + activeHref + '> was not found in configured table');
return -1;
};

How to detect mouseleave() on two elements at once?

Answer can be in vanilla js or jQuery. I want to hide a div with the id "myDiv" if the user is no longer hovering over a link with the id "myLink" or a span with the id "mySpan". If the user has his mouse over either element "myDiv" will still show, but the second the user is not hover over either of the two (doesn't matter which element the user's mouse leaves first) "myDiv" will disappear from the face of existence.
In other words this is how I detect mouse leave on one element:
$('#someElement').mouseleave(function() {
// do something
});
but how to say (in a way that will actually work):
$('#someElement').mouseleave() || $('#someOtherElement').mouseleave()) {
// do something
});
How to detect this?

Something like this should work:
var count = 0;
$('#myLink, #mySpan').mouseenter(function(){
count++;
$('#myDiv').show();
}).mouseleave(function(){
count--;
if (!count) {
$('#myDiv').hide();
}
});
jsfiddle

You could use a multiple selector:
$("#someElement, #someOtherElement").mouseleave(function() {
// Do something.
});

You can beautifully use setTimeout() to give the mouseleave() function some "tolerance", that means if you leave the divs but re-enter one of them within a given period of time, it does not trigger the hide() function.
Here is the code (added to lonesomeday's answer):
var count = 0;
var tolerance = 500;
$('#d1, #d2').mouseenter(function(){
count++;
$('#d3').show();
}).mouseleave(function(){
count--;
setTimeout(function () {
if (!count) {
$('#d3').hide();
}
}, tolerance);
});
http://jsfiddle.net/pFTfm/195/

I think, it's your solution!!!
$(document).ready(function() {
var someOtherElement = "";
$("#someElement").hover(function(){
var someOtherElement = $(this).attr("href");
$(someOtherElement).show();
});
$("#someElement").mouseleave(function(){
var someOtherElement= $(this).attr("href");
$(someOtherElement).mouseenter(function(){
$(someOtherElement).show();
});
$(someOtherElement).mouseleave(function(){
$(someOtherElement).hide();
});
});
});
----
html
----
<div id="someElement">
<ul>
<li>element1</li>
<li>element2</li>
</ul>
</div>
<div id="tab1" style="display: none"> TAB1 </div>
<div id="tab2" style="display: none"> TAB1 </div>

While the answer from lonesomeday is perfectly valid I changed my html to have both elements in one container. I originally wanted to avoid this hence I had to do more refactoring for my clients in other html templates, but I think it will pay out on the long term.
<div id="my-container">
<div class="elem1">Foo</div>
<div class="elem2">Bar</div>
</div>
$('#my-container').mouseleave(function() { console.log("left"); });
