jQuery .click() activates addClass() & class uses transform: translate to move element - javascript

I am making an image slider with two arrows on either side of the slider. For instance, when .click() the .rightArrow, a class is added ( .addClass() ) called .moveRight.
.moveRight{
transform: translate(760px,0);
-webkit-transform: translate(760px,0); /** Safari & Chrome **/
-o-transform: translate(760px,0); /** Opera **/
-moz-transform: translate(760px,0); /** Firefox **/
}
The problem is that this click event only triggers once. I imagine this is because I am telling the moveable element to go to a specific location.
I want to the element to keep moving right for a certain amount of px every time I .click() the .rightArrow.
The jQuery
$( document ).ready(function() {
$('.rightArrow').click( function() {
$('.imgGluedToThis').removeClass("moveLeft");
$('.imgGluedToThis').addClass("moveRight");
});
$('.leftArrow').click( function() {
$('.imgGluedToThis').removeClass("moveRight");
$('.imgGluedToThis').addClass("moveLeft");
});
});
Here is the HTML
<img src="rightArrow.png" class="rightArrow">
<img src="leftArrow.png" class="leftArrow">
<div class="pictures-container">
<div class="imgGluedToThis">
<div class="picture-container">
<a href="#openModal1">
<img src="house.png" class="picture">
</a>
</div>
<div class="picture-container">
<a href="#openModal1">
<img src="building.png" class="picture">
</a>
</div>
<div class="picture-container">
<a href="#openModal1">
<img src="house2.png" class="picture">
</a>
</div>
<div class="picture-container">
<a href="#openModal1">
<img src="house.png" class="picture">
</a>
</div>
<div class="picture-container">
<a href="#openModal1">
<img src="building.png" class="picture">
</a>
</div>
<div class="picture-container">
<a href="#openModal1">
<img src="house2.png" class="picture">
</a>
</div>
</div>
</div>

Use css() method in jQuery
$(document).ready(function() {
$('.rightArrow').click( function() {
$('.imgGluedToThis').css('left','+=10px');
});
$('.leftArrow').click( function() {
$('.imgGluedToThis').css('left','-=10px');
});
});
FIDDLE
Or use animate() method
$(document).ready(function() {
$('.rightArrow').click( function() {
$('.imgGluedToThis').animate({'left':'+=10px'});
});
$('.leftArrow').click( function() {
$('.imgGluedToThis').animate({'left':'-=10px'});
});
});
FIDDLE

The click event is triggering correctly every time - translate will move an element to a specific position. If it is already 760px across and click is called again to move it to 760px, nothing appears to happen.
You could set up a few classes to define where the leftmost, rightmost etc images should display, updating the classes for each element accordingly.
If the slider needs to be infinite, you will need to update the DOM too to set the elements to the correct order, updating the classes again once you have done so.

If you want to use translate, specifically, you will need to track it and change it with code, perhaps like this:
jQuery(function ($) {
// closures
var iImageIndex = 0;
var iSlideWidth = 760;
var iImageMax = $('.picture-container').size();
var $slides = $('.imgGluedToThis');
var fTranslate = function (iDirection) {
iDirection = (iDirection && (iDirection < 0) ) ? -1 : 1; // normalize direction
iImageIndex = iImageIndex + iDirection; // increment direction
iImageIndex = iImageIndex < 0 ? iImageMax + iImageMax : iImageIndex; // check left end
iImageIndex = iImageIndex % iImageMax; // check right end
$slides.css('transform', 'translate(' + (iSlideWidth * iImageIndex) + 'px, 0)');
}
// event methods (closures)
var fClickLeft = function () {
fTranslate(-1);
};
var fClickRight = function () {
fTranslate(1);
};
// event handlers
$('.rightArrow').click(fClickRight);
$('.leftArrow').click(fClickLeft);
});

Creating a div slider in jquery

I am trying to make an image change when I click on a piece of text on a website that I am building.
At this moment I have created a class called device with one of them being device active as shown below:
<div class="col-md-3">
<div class="device active">
<img src="app/assets/images/mockup.png" alt="">
</div>
<div class="device">
<img src="app/assets/images/mockup.png" alt="">
</div>
<div class="device">
<img src="app/assets/images/mockup.png" alt="">
</div>
</div>
And then what i am currently trying to do is remove the class of active when I click on some text with the i.d of #search2. This is my whole jquery script so far:
$("#search2").click(function() {
var currentImage = $('.device.active');
var nextImage = currentImage.next();
currentImage.removeClass('active');
});
However this does not seem to remove the class of active and the image is still displayed? any ideas?
Your selection is done right and it is working for me (the active class is removed from that item). The problem must be somewhere else in your code.
Here is an alternative:
var activeDeviceIndex = 0;
$("#search2").click(function() {
var devicesContainer = $('.device');
$(devicesContainer[activeDeviceIndex]).removeClass('active');
activeDeviceIndex === devicesContainer.length - 1 ? activeDeviceIndex = 0 : activeDeviceIndex++;
$(devicesContainer[activeDeviceIndex]).addClass('active');
});
.device {
display: none;
}
.device.active {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-3">
<div class="device active">
<p>Device 1</p>
</div>
<div class="device">
<p>Device 2</p>
</div>
<div class="device">
<p>Device 3</p>
</div>
</div>
<button id="search2">click</button>
Check on the following, the id on the button to click should be search2 and not #search2, may be just typo stuffs.
after that update your code as follows
/**
*#description - gets the next image to slide, if the last image is the current image, it will loop the sliding
*#param {Element} current - the currently active image
*#param {Boolean} islooped - boolean value indicating if a looping just started
*/
var nextImage = function(current, islooped) {
var next = islooped? current : current.nextSibling;
while(next && next.nodeName.toLowerCase() !== 'div') {
next = next.nextSibling;
}
next = next? next : nextImage(current.parentNode.firstChild, true);
return next;
};
$('#search2').bind('click', function(event) {
var current = $('.device.active').removeClass('active').get(0);
var next = nextImage(current, false);
$(next).addClass('active');
});

Add Class to Following Element

I had a look out on the interwebs for a jQuery image gallery and couldn't find one that suited what I wanted to do. So I, ended up creating one myself and am trying to figure out how to get the prev and next buttons to work.
<div class="gallery portrait">
<nav>
<div class="close"></div>
<div class="prev"></div>
<div class="next"></div>
</nav>
<div class="cover">
<img src="image.jpg">
</div>
<ul class="thumbs">
<li class="thumb">
<img src="image.jpg">
</li>
...
</ul>
</div>
I'm also using a bit of jQuery to add a class of .full to the .thumb a element, which makes the thumbnails go fullscreen.
$( ".thumb a" ).click(function() {
$( this ).toggleClass( "full" );
$( "nav" ).addClass( "show" );
});
Now I can't work out this next bit, I need a way when the .prev or .next buttons are clicked for it to remove the class of .full from the current element and add it to the next or previous .thumb a element, depending on which was clicked.
I've got a demo setup here: http://codepen.io/realph/pen/hjvBG
Any help is appreciated, thanks in advance!
P.S. If this turns out well, I plan on releasing it for free. I guess you can't have too many jQuery image galleries, eh?
You can use $.next() and $.prev():
$(".prev").click(function () {
var current = $('.full');
current.prev('.thumb').addClass('full');
current.removeClass('full');
return false; // stop propagation; prevents image click event
});
$(".next").click(function () {
var current = $('.full');
current.next('.thumb').addClass('full');
current.removeClass('full');
return false; // stop propagation; prevents image click event
});
I suggest the following additions to your code to handle wrapping around with your next and previous links:
$(".next").click(function (event) {
navigate("next");
return false;
});
$(".prev").click(function (event) {
navigate("prev");
return false;
});
function navigate(operation) {
var $thumbs = $(".thumb"),
$full = $thumbs.find("a.full").closest(".thumb"),
$next;
$thumbs.find('a').removeClass('full');
if (operation == 'prev' && $full.is($thumbs.first()))
$next = $thumbs.last();
else if (operation == 'next' && $full.is($thumbs.last()))
$next = $thumbs.first();
else
$next = $full[operation]();
$next.find('a').click();
}
Here is a forked CodePen.
Something like this will get you started, but what you're wanting to do takes a little time to get just right.
<script type="text/javascript">
var imgSrcs = ['/imgs/this.jpg', '/imgs/will.jpg', '/imgs/work.jpg', '/imgs/just.jpg', '/imgs/fine.jpg'];//img url loaded into an array
var btnPrev = document.getElementById('prev'),
btnNext = document.getElementById('next'),
cover = document.getElementById('cover'),
thumb = document.getElementById('thumb'),
currImgIx = 0;
btnPrev.onclick = function () {
if (currImgIx === 0) { return; };
currImgIx--;
cover.src = imgSrcs[currImg];
thumb.src = imgSrcs[currImgIx];
};
btnNext.onclick = function () {
if (currImgIx === imgSrcs.length - 1) { return; };
currImgIx++;
cover.src = imgSrcs[currImgIx];
thumb.src = imgSrcs[currImgIx];
};
</script>
<div class="gallery portrait">
<nav>
<div class="close">X</div>
<div id="prev" class="prev">Prev</div>
<div id="next" class="next">Next</div>
</nav>
<div class="cover">
<img id="cover" src="image.jpg">
</div>
<ul class="thumbs">
<li class="thumb">
<img id="thumb" src="image.jpg">
</li>
...
</ul>
</div>

Add one or two pictures to the jQuery Slider

I need to add a jQuery slider to my website and I found this one met my requirement. But the slider just show 3 pictures, how to add one or two other pictures to the slider?
Demo: http://d.lanrentuku.com/down/js/jiaodiantu-883/
The html code
<div id="preview-slider">
<div id="preview-slide-1" style="display: none;"><a target="_blank" href="http://www.lanrentuku.com/"><img width="930" height="300" alt="" src="images/01.jpg"></a></div>
<div class="preview-hide" id="preview-slide-2" style="display: block;"><a target="_blank" href="http://www.lanrentuku.com/"><img width="930" height="300" alt="" src="images/02.jpg"></a></div>
<div class="preview-hide" id="preview-slide-3" style="display: none;"><a target="_blank" href="http://www.lanrentuku.com/"><img width="930" height="300" alt="" src="images/03.jpg"></a></div>
<div id="preview-slider-line">
<ul id="preview-slider-holder">
<li class="preview-first">
<div class="preview-slider-thumbnail"><a target="_blank" href="http://www.lanrentuku.com/"><img width="66" height="36" id="preview-thumbnail-im1" alt="" src="images/01.png" style="top: 0px;"></a></div>
<span><a target="_blank" href="http://www.lanrentuku.com/">Picture 1</a></span></li>
<li class="preview-second">
<div class="preview-slider-thumbnail"><a target="_blank" href="http://www.lanrentuku.com/"><img width="66" height="36" id="preview-thumbnail-im2" alt="" src="images/02.png" style="top: -15px;"></a></div>
<span><a target="_blank" href="http://www.lanrentuku.com/">Picture 2</a></span></li>
<li class="preview-third">
<div class="preview-slider-thumbnail"><a target="_blank" href="http://www.lanrentuku.com/"><img width="66" height="36" id="preview-thumbnail-im3" alt="" src="images/03.png" style="top: 0px;"></a></div>
<span><a target="_blank" href="http://www.lanrentuku.com/">Picture 3</a></span></li>
</ul>
</div>
</div>
The javascript code
(function($){
$(document).ready(function() {
var ready = true, position = 1, timer = null, domer = $('ul#preview-slider-holder > li');
var anima = function () {
if (!ready) {
$("#preview-slider > div:not(':last'):not(':eq(" + position + ")')").each(function(){
if($(this).is(':animated')){
$(this).stop(true, true);
}
});
}
ready = false;
$("#preview-slider > div:not(':last'):not(':eq(" + position + ")')").hide();
$('img', this).animate({"top": "-15px"}, 200);
$('#preview-slide-' + (position + 1)).fadeIn(600, function(){
ready = true;
});
$('img[id^="preview-thumbnail-im"]:not([id="preview-thumbnail-im' + (position+1) + '"])').stop(true, false).animate({'top': '0px'}, 200);
position = ++ position % 3;
};
timer = setInterval(function(){anima.apply(domer)}, 2000); // interval time
domer.mouseover(function () {
timer == null || clearInterval(timer);
if($(this).hasClass('preview-first')){
position = 0;
} else if($(this).hasClass('preview-second')){
position = 1;
} else if($(this).hasClass('preview-third')){
position = 2;
}
anima.apply(this);
});
domer.mouseout(function () {
timer = setInterval(function(){anima.apply(domer)}, 2000);
});
});
})(jQuery);
I tried to add a li element , but it didn't work. I think I need to modify the javascript code. But I am not good at the programming, will someone tell how to do?
While I agree with DevlshOne, that many other quality sliders are out there. To answer the OP's question, you have to fix the code to not have hard-coded positions. Instead, I chose to use the index method present with jQuery.
Here is the jsFiddle that shows 4 images working (though I used the original code, so no actual images are displayed).
http://jsfiddle.net/a5yqx/
The key changes to the code are from:
position = ++ position % 3;
...
if($(this).hasClass('preview-first')){
position = 0;
} else if($(this).hasClass('preview-second')){
position = 1;
} else if($(this).hasClass('preview-third')){
position = 2;
}
To:
position = ++position % domer.length;
...
position = $(this).index();
Since I don't have the CSS to accompany it, I'm not sure what else you'll need to keep your style up, but good luck.
Last note, I changed the image size from your default to 10x10 in order to see it on my screen in the fiddle.

If class also is class then.. move active class on click

(New at jQuery)
Trying to write a function that moves an active class along as an arrow is clicked..
html
<div id="steps">
<a href="#1" data-ref="dynamic-tabs slider-id">
<div class="step step-1 active">
<div class="step-img">
<img width="175" height="120" src="http://site.com/img.png">
</div>
<div class="step-title">Schedule Online or Wave Down a Biker</div>
<div class="step-over"></div>
</div>
</a>
<a href="#2" data-ref="dynamic-tabs slider-id">
<div class="step step-2">
<div class="step-img">
<img width="175" height="120" src="http://site.com/img.png">
</div>
<div class="step-title">We Bike to & Clean Your Car</div>
<div class="step-over"></div>
</div>
</a>
<a href="#3" data-ref="dynamic-tabs slider-id">
<div class="step step-3">
<div class="step-img">
<img width="175" height="120" src="http://site.com/img.png">
</div>
<div class="step-title">Come Back to a Clean Car</div>
<div class="step-over"></div>
</div>
</a>
</div>
<div class="nav-right" data-dir="next" title="Slide right">
right »
</div>
jQuery I'm trying
$(".nav-right a").click(function() {
if( $(".step-1").is('.active') ) {
$(".step-1").removeClass("active");
$(".step-2").addClass("active");
}
});
$(".nav-right a").click(function() {
if( $(".step-2").is(".active") ) {
$(".step-2").removeClass("active");
$(".step-3").addClass("active");
}
});
$(".nav-right a").click(function() {
if( $(".step-3").is(".active") ) {
$(".step-3").removeClass("active");
$(".step-1").addClass("active");
}
});
The problem seems to be that you create 3 (sic!) event handlers which fire sequentially when you click the link.
The first handler, as step 1 is active, sets step 2 to active.
The second handler, as step 2 is now active, sets step 3 to active
The third handler, as step 3 is now active, sets step 1 to active again.
In the end, nothing has happened.
Solution: Use only one event handler, and if-else-statements instead of only if-statements:
$(".nav-right a").click(function() {
if( $(".step-1").is('.active') ) {
$(".step-1").removeClass("active");
$(".step-2").addClass("active");
} else if( $(".step-2").is(".active") ) {
$(".step-2").removeClass("active");
$(".step-3").addClass("active");
} else if( $(".step-3").is(".active") ) {
$(".step-3").removeClass("active");
$(".step-1").addClass("active");
}
});
Of course, we can do much better and write a generic function, which also does not need the step-N classes:
var rotatedElements = $(".step");
$(".nav-right a").click(function() {
var cur = rotatedElements.filter(".active");
cur.removeClass("active");
var index = rotatedElements.index(cur) + 1;
if (index >= rotatedElements.length)
index = 0;
rotatedElements.eq(index).addClass("active");
});
As suggested in comment by theScientist you should use only one event handler.
$(".nav-right a").click(function() {
if( $(".step-1").is('.active') ) {alert('1');
$(".step-1").removeClass("active");
$(".step-2").addClass("active");
return;
}
if( $(".step-2").is(".active") ) {alert('2');
$(".step-2").removeClass("active");
$(".step-3").addClass("active"); return;
}
if( $(".step-3").is(".active") ) {alert('3');
$(".step-3").removeClass("active");
$(".step-1").addClass("active"); return;
}
});
Here it is in a single handler and about as concise as I can make it :
$(".nav-right a").click(function() {
var $steps = $(".step"),
index = $steps.filter('.active').removeClass("active").index();
$steps.eq((index + 1) % $steps.length).addClass('active');
});
There's a couple of problems here, but to address the question you could simplify your code to just this and remove the dependency on .step1, .step2, etc in case you decide to add more steps.
$('.nav-right').find('a').on('click', function(e) {
e.preventDefault();
var $activeStep = $('.step.active'),
$expectedNextStep = $activeStep.closest('a').next().find('.step'),
$nextActiveStep = $expectedNextStep.length ? $expectedNextStep : $('.step').first();
$activeStep.removeClass('active');
$nextActiveStep.addClass('active');
});
​
However; I would highly recommend putting this in an ordered list, and not wrapping block elements in an anchor. The page will work as you have it but it's just poor semantics.

How to zoom in a group of element using jqzoom

I'm using Jqzoom to provide zoom for a given image. These images are placed side by side and each one have the same size. I want to find a way to make the same zoom happen on all images in the same time.
Code # jsfiddle: http://jsfiddle.net/Fam43/23/
Sample IMG:
Sample HTML code:
<div>
<!-- Omitted stuff here -->
<a href="img1_big.png" class="zoom">
<img src="img1.png" width="100%" />
</a>
</div>
<div>
<!-- Omitted stuff here -->
<a href="img2_big.png" class="zoom">
<img src="img2.png" width="100%" />
</a>
</div>
<div>
<!-- Omitted stuff here -->
<a href="img3_big.png" class="zoom">
<img src="img3.png" width="100%" />
</a>
</div>
JQZoom function:
$('.zoom').jqzoom({
zoomType: 'innerzoom'
});
After having a think about the situation i came up with the folowing:
in jqZoom 2.3 in the first section there is an $.extend(obj. { and one of the members is init: in that function replace the section setting the mouse events with:
At the end of the mouseenter mouseover event:
$(".zoomPad", el).bind('mouseenter mouseover', function(event) {
// *snip
if (settings.linked && event.srcElement === this) {
$(settings.linked).not(el).find(".zoomPad").trigger('mouseover');
}
});
Change mouseleave function like so:
$(".zoomPad", el).bind('mouseleave', function(event, notSource) {
obj.deactivate();
if (settings.linked && !notSource) {
$(settings.linked).not(el).find(".zoomPad").trigger('mouseleave', [true]);
}
});
the mouse move function needs to have the parameters changed and the code at the beginning and end of the function added:
$(".zoomPad", el).bind('mousemove', function(e, thisx, thisy) {
if (thisx && thisy) {
e = $.extend(e, {
pageX: (thisx + this.offsetLeft),
pageY: (thisy + this.offsetTop)
});
}
// *snip*
if (settings.linked && !(thisx && thisy)) {
$(settings.linked).not(el).find(".zoomPad").trigger('mousemove', [e.pageX - this.offsetLeft, e.pageY - this.offsetTop]);
}
});
my example:
http://jsfiddle.net/7FQHt/
Integrated OP's example:
http://jsfiddle.net/Fam43/24/
You can even limit the linking to just one item: http://jsfiddle.net/Fam43/25/ OR http://jsfiddle.net/Fam43/26/
This might not make 100% sense to you and that is ok, just ask me a question. Some things make sense in my head and not yours.
