jQuery: Why is by box collapsing on first click - javascript

The homepage of our website (legendboats.com) is 4 small cells, that if you click on, the large image changes. Pretty standard stuff, but there is a problem.
When you click on one of them the first time, the large area collapses before the new image reappears. This doesn't happen again, you can continue to click on different images, and they will fade in and out properly. Here is the code I'm using:
$('.home_boxes a.content_box').on('click', function(e) {
e.preventDefault();
var new_slide = this.hash;
$('#home_box div.active').fadeOut(function() {
$('#home_box ' + new_slide).fadeIn().addClass('active');
}).removeClass('active');
});
Any ideas on what I'm doing wrong, or any improvements?

It collapses because you're removing the class="active".
The reason it doesn't collapse after the first time is because jQuery is adding an inline style "display:block" which overrides the missing class="active".
Initially:
<div id="standard_equipment" class="active">
Subsequently:
<div id="more_power" style="display: block;" class="active">

Well I don't know why it happens, but I can see the symptoms. For some reason on first click the content collapses. This causes the odd flashing. If you set a min-height on home_box it sorts it out.
#home_box { min-height: 482px; }

Try doing this way
$('.home_boxes a.content_box').on('click', function(e) {
e.preventDefault();
var new_slide = this.hash;
$('#home_box div.active').fadeOut(function() {
var parent = this;
$('#home_box ' + new_slide).fadeIn(function(){
//You can shuffle following two lines and try
$(parent).removeClass('active');
$(this).addClass('active');
});
});
});
Hope this works you.

Showing a div when an image in a slider is active

I am working with a plugin image slider and am attempting to show specific text that will be associated with image. For instance, image 1 will show paragraph 1, image 2 will show paragraph 2, etc.
I was going to upload a snippet showing what I am doing, but the plugin code was too much. Therefore, here is a jsfiddle link that shows what I am doing. The main code in question is at the bottom of the javascript and the text that I want to show is at the bottom of the html. This code:
$(document).ready(function() {
$('.ma5slider').ma5slider();
var court = $('#slide-1');
var activeSlide = $('.slide--active') == true;
if(court == activeSlide) {
court.show();
console.log('It is working');
}
});
I have the text set at display: none; on page load and then when the specific image is displaying (I believe I narrowed this down to the class .slide--active), that text set to show().
Does anyone see what I am doing wrong?
This is because you are not targeting the right active class when each slide takes turn to slide in, I have amended your code below:
$(document).ready(function() {
$('.ma5slider').ma5slider();
var court = $('.slide');
var activeSlideClassName = 'slide--active';
setInterval(function(){
if(court.hasClass(activeSlideClassName)){
console.log('It is working');
}
}, 1000);
});
Also your slide will need to have a callback function to capture the event whenever the new slide comes in. In this case I have used setInterval() to monitor the DOM, it isn't the best solution but you get the idea....
Working code here
you can check it $('.ma5slider').on('ma5.activeSlide') same as below :

Jquery accordion not collapsing

So im busy creating a Newsletter archive by using a Jquery accordion for my client. Each month in essence is an accordion (So the month itself is expandable and collapsible) and every article too. My first month (January) is working perfectly but for some reason, none of the others work as expected. The other "months" can expand and collapse but not their articles. I have tried amending the Javascript countless times but to no avail.
Here is the link to the test site:
http://promisedev.co.za/eam/gt/
If anybody has any suggestions or advice it would be greatly appreciated!
i think the problem is with your jquery.akordeon.js file. you can delete this file and use this JQuery code. I edited your code you can use this:
jsFiddle is here
$(document).ready(function(){
//Hide the tooglebox when page load
$(".togglebox").hide();
$(".togglebox:first").show();
$(".akordeon-item-head").next(".akordeon-item-body").hide();
//slide up and down when click over heading 2
$("h1").click(function(){
// slide toggle effect set to slow you can set it to fast too.
$(this).next(".togglebox").slideToggle("slow");
return true;
});
/* here is the new Codes*/
$(".akordeon-item-head").click(function(){
$(this).next(".akordeon-item-body").slideToggle();
});
});
All you have to do is remove inline styles such as height: 154px and height: 0 and set height in a local/external css:
<style>
.akordeon-item-body { height: 154px; }
</style>
I had to use an accordeon mechanism on some site and finally ended up coding it on my own
Fiddle test case <HERE>
The important part is to store last slided element
$("#commonAncestor").on('click', function (e) {
var $me = $(this),
$clicked = $(e.target).closest('.clickableArea', this),
$lastClicked = $me.data('active') || $([]),
...
});

Scrollable DIV scrolls to top when TD is clicked

I have an interesting problem that I cannot seem to find an answer for on Google. I have a scrollable div that a simple table in it. There are 'heading' rows ('.sl-bucket') that when clicked the script shows the associated rows below that, hiding other shown rows. In Chrome and IE, there is no issues. In Firefox on a fresh load, when you click the first element, it scrolls the div back to the top. Everything else works great after that.
Any thoughts on how I could fix this?
Here is the example jsFiddle.
Here is my javscript:
$(window).on('click', '.sl-bucket', function() {
var bucket = $(this).attr('rel');
if ($('.sl-'+bucket).is(':visible') == false) {
$('.sl-unitRow:visible').hide();
$('.sl-'+bucket).show();
} else {
$('.sl-'+bucket).hide();
}
return false;
});
Working for me by using
$('.sl-'+bucket).css("display", "block");
instead of
$('.sl-'+bucket).show();

Hovering over <a> and displaying images based on value

I am currently displaying pictures when an tag is hover over. I have been able to workout the main problem of displaying the picture. The problem is that it has a glitch when hovering occurs quickly. Is there away to avoid that? Also how can i set a default image to display when page is loaded? JSFIDDLE
HTML
<div id="links">
Cheeseburger »
Tacos »
Salads »
Bread Sticks »
Dessert »
</div>
Jquery
$("div#links > a").hover(
function(){
var ID = $(this).data("content");
$("div#images").children("img#" + ID).fadeIn("slow");
},
function() {
var ID = $(this).data("content");
$("div#images").children("img#" + ID).hide();
}
);​
Glitch
The problem is that it has a glitch when hovering occurs quickly. Is
there away to avoid that?
This is not a glitch. fadeIn is using animation. As you are hovering over the links faster than the animations complete your experiencing that "glitch".
To ensure you are not clashing with the previous running animation you have to stop any current and any queued animation.
Replace
$("div#images").children("img#" + ID).fadeIn("slow");
with
$("div#images").children("img#" + ID).stop(true, true).fadeIn("slow");
DEMO - Clearing the animation queue before starting the next one
how can i set a default image to display when page is loaded?
I added the code to show a default image as well. To prevent any odd visuals when hovering over a menu item the first time when using a default image. The code checks if we are showing a default image and if we are it will further check if the image for the current menu is the default image.
If it is, it won't hide it as it is showing it anyway but if it is not, it will ide the default image before fading in the new one.
Hope this makes sense, see the full code and DEMO below.
// Indicates if default image is shown
var showingDefaultImage = true;
var $images = $("div#images");
var $defaultImage = $images.children("img#tacos");
// Display a default image
$defaultImage.show();
$("div#links > a").hover(
function() {
var ID = $(this).data("content");
var $image = $images.children("img#" + ID);
if (showingDefaultImage) {
showingDefaultImage = false;
if (!$image.is($defaultImage)) {
$defaultImage.hide();
}
}
$image.stop(true, true).fadeIn("slow");
}, function() {
$images.children().hide();
});​
DEMO - Showing a default image
The code in the above DEMO is also a little more optimized by caching the selectors.
would it be possible to leave up the most recent image from the last
hovered tag ?(instead of hiding the image and leaving a blank)
If I understood you correctly you don't want to hide the image when you leave menu with your mouse but instead want to leave the image of the menu you last hovered over visible.
To do that you remove the second function of the hover and as it is no longer needed you can now attach the mouseenter event instead.
var $images = $("div#images");
var $currentImage = $images.children("img#tacos");
$currentImage .show();
$("div#links > a").mouseenter(function() {
var ID = $(this).data("content");
var $image = $images.children("img#" + ID);
if (!$image.is($currentImage)) {
$currentImage.hide();
}
$currentImage = $image;
$image.stop(true, true).fadeIn("slow");
});
DEMO - Fading in images on mouseenter and leaving last image visible
The above code includes caching of selectors for optimisation and the logic to ensure no "flickering" occurs when the new hovered menu item is the same as the last one which was hovered.
See http://jsfiddle.net/7Wp9z/7/
As François Wahl said, use stop to stop the animations. But instead of using data-content and IDs, I think that you could use index:
HTML:
<div id="links">
Cheeseburger »
Tacos »
Salads »
Bread Sticks »
Dessert »
</div>
<div id="images">
<img src="http://media.smashingmagazine.com/wp-content/uploads/images/brand-ux/cb.jpg">
<img src="http://adventuresoflittlemiss.files.wordpress.com/2012/07/tacos.jpg">
<img src="http://www.growingappetite.com/wp-content/uploads/2011/05/chicken-salad1.jpg">

<img src="http://1.bp.blogspot.com/-IaURSrV70LI/T4YzPubl9EI/AAAAAAAAGSg/AEdd-eLuJUk/s1600/Cooking+Weekly.jpg">
</div>
JavaScript:
$("div#links > a").hover(
function(){
$("#images>img")
.hide()
.stop(true,true)
.eq($(this).index()).fadeIn("slow");
},
function() {
$("#images>img").hide();
}
);
Have you tried not specifying which children should hide on the mouse-out portion?
$("div#links > a").hover(
function(){
var ID = $(this).data("content");
$("div#images").children("img#" + ID).fadeIn("slow");
},
function() {
$("div#images").children().hide();
}
);​
The glitch probably occurs because the image isn't loaded yet, you should look up some preloading technique. You will always have to wait for the relevant images to be loaded though before you can show them.
But you could enhance the user experience by either indicating that the images are getting loaded or by simply not activating the hovering effect until the images are loaded.
I'd probably go with the last case since I'm lazy but thats just me.
A simple preloading technique is to declare several id's with different background images and then changing the id dynamically using javascript and thus showing the image.
$("#id-of-element").attr('id','preloaded-bg-div');

jQuery slide/fade functions

I'm trying to modify this snippet:
$(document).ready(function(){
$('.showscript').show();
$("div.content:not(.about)").hide();
$(".subnav a, .mainnav a").click(function(){
//remove possible hilights
$(".subnav a, .mainnav a").removeClass("active");
var href = $(this).attr("href");
//hilight the clicked link
$('a[href="'+href+'"]').addClass("active");
//hide possible shown content
$(".content").hide();
//show my content
$("div.content:has(a[name='" + href.replace("#","") + "'])").show();
});
});
So that when a link in the .subnav or .mainnav is clicked it animates the swap it's doing. I'd like to use jQuery's fadeIn/Out, but I'm not really sure how I could apply it to this? The script is very specific to allow the content to show from either the mainnav and subnav and change active class on both when either is clicked.
You can see what I mean here:
http://banderdash.net/design
But it feels much to choppy.
In addition to quickly fading out the content and quickly fading in the new content, I would like the window to slide down to the content space. I'm just using anchors like this:
<a name="work">
and then calling like this:
<a href="#work">
Which jumps the window down as far as it can, but because the content in the black isn't always enough to make a Y plane that would allow the white space on the top to be moved out of the viewable rang. So I think a slide would work much better. How can I tell it to slide down the value of the href on click?
first of all i wouldnt used named anchors. I could make those ids on divs that are children of content. That way you dont have to do any real selction on complex expresstions just a search on id for the div within content. Secondly this allows you to animate each div indivdually. ehich i think is goign to give you the most control. Lastly you need to return false, from your click handler otherwise its goign to do the normal "jump to" type functionality. My script might look something like this:
Content:
<div class="content">
<div id="about"> ... </div>
<div id="work"> ... </div>
<div id="education"> ... </div>
</div>
Relevant part of your onready:
$(document).ready(function(){
$(.subnav a, .mainnav a).click(function(){
$(".subnav a, .mainnav a").removeClass("active");
var selector = $(this).attr('href');
$('a[href="'+selector+'"]').addClass("active");
if($(selector, '.content').length > 0){
$('> :visible', '.content').slideUp('fast', function(){
$(this).fadeOut('fast', function(){
$(selector, '.content').fadeIn('fast', function(){
$(this).slideDown('fast');
});
});
});
}
return false;
});
});
Note that is only pseudo code so a simpel c&p may or may not work. but it should give you an idea.
