jQuery interval won't restart after hover out - javascript

After calling a PHP function, which generates the HTML,
I call the function below for the specific slider id.
That works fine, hover pauses the slideshow, also ok.
But when I am hovering out of the section, firebug gives the following error:
TypeError: o.handler.apply is not a function
And the slideshow won't continue.
Thanks in advance.
function CallSlider(sliderid){
var $slider = $('#'+sliderid);
var $slide = 'li';
var $transition_time = 1000; // 1 second
var $time_between_slides = 2000; // 4 seconds
function slides(){
return $slider.find($slide);
}
slides().fadeOut();
// set active classes
slides().first().addClass('active');
slides().first().fadeIn($transition_time);
$('#'+sliderid).hover(function() {
clearInterval(sliderid);
}, sliderid = setInterval(
function(){
var $i = $slider.find($slide + '.active').index();
//alert('test');
slides().eq($i).removeClass('active');
slides().eq($i).fadeOut($transition_time);
if (slides().length == $i + 1) $i = -1; // loop to start
slides().eq($i + 1).fadeIn($transition_time);
slides().eq($i + 1).addClass('active');
}
, $transition_time + $time_between_slides
)
);
}

I believe that error is related to the fact that hover() expects parameters to be functions.
Type: Function() - A function to execute when the mouse pointer enters/leaves the element.
http://api.jquery.com/hover/
I suggest putting your "hover off" code in its own function, like so:
$('#'+sliderid).hover(
function() {
// hover over
clearInterval(sliderid);
},
function () {
// hover off
sliderid = setInterval(...);
}
);
EDIT:
Here's an example, based on the code you provided, of how to keep things flexible (i.e. for dynamic lists).
var slide = 'li';
var transition_time = 1000; // 1 second
var time_between_slides = 2000; // 4 seconds
function startCycle($slider, $slides) {
return setInterval(
function () {
var $thisslide=jQuery(slide+'.active',$slider);
var $nextslide=($thisslide.next(slide).length?$thisslide.next(slide):$slides.eq(0));
$thisslide.removeClass('active').fadeOut(transition_time);
$nextslide.fadeIn(transition_time).addClass('active');
}, transition_time + time_between_slides
);
}
jQuery('ul.slider').each(function () {
var sliderid;
var $slider = jQuery(this);
var $slides = $slider.find(slide);
$slides.fadeOut();
// set active classes
$slides.first().addClass('active').fadeIn(transition_time);
$slider.hover(
function () {
// hover over
clearInterval(this.sliderid);
},
function () {
// hover off
this.sliderid = startCycle($slider, $slides);
}
);
this.sliderid = startCycle($slider, $slides);
});

How to implement codepen jquery script in wordpress?

I am trying to implement a fancy slider from codepen in wordpress. I have correctly added the script using the enqueue script method. I know I did it coorectly because it worked for a very small experiment I tried. Now the pen is: http://codepen.io/suez/pen/wMMgXp .

The javascript code can e found above and in the mentioned link.I know that in wordpress we have to use jQuery in place of $ but I still can't seem to figure out how to do it in this case. And one more thing, the css is in scass form but I have taken the compiled css form but I don't think that is causing any problem (rignt?) Everything I have tried till this point has failed. Any help will be appreciated
You can use $ instead of jQuery in WordPress so long as you wrap all your code inside the following:
(function($) {
// Your code goes here
})( jQuery );
If the code is in the header (before the document is ready) then instead use:
jQuery(document).ready(function( $ ) {
// Your code goes here
});
If your code is still having problems, then please include both the enqueue code in your theme and the error messages

jQuery extending my vertical tabs

Im new to jQuery and wanting to make this a little cleaner and also add functionality but not sure on how rto do it so hoping someone could give me a hand.
tabs (working) so far
$(".tabs-menu a").click(function(event) {
event.preventDefault();
$(this).parent().addClass("active");
$(this).parent().siblings().removeClass("active");
var tab = $(this).attr("href");
$(".tab-content").not(tab).css("display", "none");
$(tab).show();
});
At the moment only works on click event but want to add something so i can add auto changing of tabs like using
hokTabs.pause();
etc.. this is mainly for when you hover an iutem it will pause and start again when you hover of button.
Anyone have any ideas?
// New Veritcal Tabs JS
(function (hokTabs, $) {
var internal = '5000'; // Internal
// start auto tabs
hokTabs.start = function () {
console.log('started');
}
// start auto tabs
hokTabs.stop = function () {
console.log('started');
}
// start auto tabs
hokTabs.pause = function () {
console.log('started');
}
}(window.hokTabs, jQuery));
These are simple start and stop functions, you just simply link them to hover events:
$(document).ready(function($) {
var activateTab = function(index) {
var tab = $(".tabs-menu li:eq(" + index + ")"),
tabContent = $(".tab div:eq(" + index + ")");
tab.addClass("current");
tab.siblings().removeClass("current");
tabContent.siblings().css("display", "none");
tabContent.show();
}
var automation = {
start: function() {
this.current = setInterval(function() {
var currentIndex = $(".tabs-menu li.current").index(),
max = $(".tabs-menu li.current").parent().children().length;
activateTab(currentIndex + 1 < max ? currentIndex + 1 : 0);
}, 2000);
},
stop: function() {
if (this.current) {
clearInterval(this.current);
}
}
}
$(".tabs-menu a").click(function(event) {
event.preventDefault();
activateTab($(event.currentTarget).parent().index());
});
automation.start();
});

clearTimeout not working - setinterval problems

i'm coding a slider ...
it have btns and it changes slides automatically.
but whene we click on buttons setInterval code is doing its work !
problem in an example :
it shoud change the slide in next 5s . ok ?
but whene we click on arrows after 2 sec
setintrelval shoud change slide automatically at next 5s.
but it change at next 3s.
// other functions ...
$(document).ready(function(){
var timeout_id = 0;
var timeout_id = setInterval( function(){next()}, 5000)
})
var originalAddClassMethod = jQuery.fn.addClass;
$.fn.addClass = function(){
var result = originalAddClassMethod.apply( this, arguments );
jQuery(this).trigger('cssClassChanged');
return result;
}
$('.customers_comment li').bind('cssClassChanged', function(){
var id = $('.customers_comment li.act').attr('data-id');
$('.customers_comment .dots a[href="#'+id+'"]').addClass(act).siblings('a').removeClass(act)
clearTimeout(timeout_id);
})
i upload the theme in here
http://demo.eagle-design.ir/amin/#sec4
You have declared timeout_id as a local variable inside the dom ready handler so it is not accessible outside that dom ready handler, so declare it outside of the dom ready handler if you want to use it in a different scope
var timeout_id;
$(document).ready(function () {
timeout_id = setInterval(function () {
next()
}, 5000)
})
I would recommend moving the event registration code also to the dom ready handlre
$(document).ready(function () {
var timeout_id = setInterval(function () {
next()
}, 5000);
$('.customers_comment li').bind('cssClassChanged', function () {
var id = $('.customers_comment li.act').attr('data-id');
$('.customers_comment .dots a[href="#' + id + '"]').addClass(act).siblings('a').removeClass(act)
clearTimeout(timeout_id);
});
});
var originalAddClassMethod = jQuery.fn.addClass;
$.fn.addClass = function () {
var result = originalAddClassMethod.apply(this, arguments);
jQuery(this).trigger('cssClassChanged');
return result;
}
timeout_id is not defined where you call clearTimeout. Try with :
$(document).ready(function(){
var timeout_id = 0;
var timeout_id = setInterval( function(){next()}, 5000)
var originalAddClassMethod = jQuery.fn.addClass;
$.fn.addClass = function(){
var result = originalAddClassMethod.apply( this, arguments );
jQuery(this).trigger('cssClassChanged');
return result;
}
$('.customers_comment li').bind('cssClassChanged', function(){
var id = $('.customers_comment li.act').attr('data-id');
$('.customers_comment .dots a[href="#'+id+'"]').addClass(act).siblings('a').removeClass(act)
clearTimeout(timeout_id);
})
})

Applying transitions to preloaded images

I'm using the jQuery plugin Images-rotation in order to create a slideshow that plays when hovering over an image. I'd like to add transitions between the images, such as jQuery's fadeIn. The images are preloaded, which is why I think what I've attempted so far hasn't been successful.
I've also created this (http://jsfiddle.net/Lydmn2xn/) to hopefully easily show what's being used, although all of the code is found in the Javascript plugin itself. So far I've tried adding variations of the line $this.fadeIn("slow"); in various spots with no luck. Below is the code for the Javascript plugin with changes I've tried to make. Not sure how to point them out as I can't bold the text in the code. (Note: said changes are not in the Jfiddle, as they don't produce any changes).
$.fn.imagesRotation = function (options) {
var defaults = {
images: [], // urls to images
dataAttr: 'images', // html5 data- attribute which contains an array with urls to images
imgSelector: 'img', // element to change
interval: 1500, // ms
intervalFirst: 1500, // first image change, ms
callback: null // first argument would be the current image url
},
settings = $.extend({}, defaults, options);
var clearRotationInterval = function ($el) {
clearInterval($el.data('imagesRotaionTimeout'));
$el.removeData('imagesRotaionTimeout');
clearInterval($el.data('imagesRotaionInterval'));
$el.removeData('imagesRotaionInterval');
},
getImagesArray = function ($this) {
var images = settings.images.length ? settings.images : $this.data(settings.dataAttr);
return $.isArray(images) ? images : false;
},
preload = function (arr) { // images preloader
$(arr).each(function () {
$('<img/>')[0].src = this;
$this.fadeIn("slow");
});
},
init = function () {
var imagesToPreload = [];
this.each(function () { // preload next image
var images = getImagesArray($(this));
if (images && images.length > 1) {
imagesToPreload.push(images[1]);
}
});
preload(imagesToPreload);
};
init.call(this);
this.on('mouseenter.imagesRotation', function () {
var $this = $(this),
$img = settings.imgSelector ? $(settings.imgSelector, $this) : null,
images = getImagesArray($this),
imagesLength = images ? images.length : null,
changeImg = function () {
var prevIndex = $this.data('imagesRotationIndex') || 0,
index = (prevIndex + 1 < imagesLength) ? prevIndex + 1 : 0,
nextIndex = (index + 1 < imagesLength) ? index + 1 : 0;
$this.data('imagesRotationIndex', index);
if ($img && $img.length > 0) {
if ($img.is('img')) {
$img.attr('src', images[index]);
$this.fadeIn('slow');
}
else {
$img.css('background-image', 'url(' + images[index] + ')');
$img.fadeIn('slow');
}
}
if (settings.callback) {
settings.callback(images[index]);
}
preload([images[nextIndex]]); // preload next image
};
if (imagesLength) {
clearRotationInterval($this); // in case of dummy intervals
var timeout = setTimeout(function () {
changeImg();
var interval = setInterval(changeImg, settings.interval);
$this.data('imagesRotaionInterval', interval); // store to clear interval on mouseleave
}, settings.intervalFirst);
$this.data('imagesRotaionTimeout', timeout);
}
}).on('mouseleave.imagesRotation', function () {
clearRotationInterval($(this));
}).on('imagesRotationRemove', function () {
var $this = $(this);
$this.off('.imagesRotation');
clearRotationInterval($this);
});
};
$.fn.imagesRotationRemove = function () {
this.trigger('imagesRotationRemove');
};
Would that do the trick if it was in the right spot, or does fadeIn/Out not apply to preloaded images? Any help or tips are appreciated.
Thanks.

Dots for Children in div. A jQuery headache - PART 2

So this is part 2 of my previous question (was advised to start a new question for this one).Just for reference here is my previous post: Dots for Children in div. A jQuery headache
My question now is: How does one go about adding an "active" class/id to the "imgdots" div for styling purposes?For example:Say I'm on image 4 then I want the 4th "imgdots" div to be another colour.Again, any help would be much appreciated! EDITI have set up a fiddle containing what I have thus far. The initial image slider was from a tutorial I followed and kinda pieced it all together from there. Here is the link: jsfiddle.net/Reinhardt/cgt5M/8/
Have you seen nth child css?
http://www.w3schools.com/cssref/sel_nth-child.asp

(function ($) {
$.fn.simpleShow = function (settings) {
var config = {

};
if (settings) $.extend(config, settings);
this.each(function () {

}
var $imgdots = $imgdotholder.children();
var timer, current = 0;
function loop() {
timer = setInterval(next, config.tranTimer);

function next(idx) {
$views.eq(current).hide();
