Selecting only one div of entire css class in jQuery - javascript

my goal is to show an overlay on a div when that div is hovered on. The normal div is called .circleBase.type1 and the overlay is circleBase.overlay. I have multiple of these divs on my page. When I hover over one .cirlceBase.type1, overlays show on every .circleBase.type1. How do I prevent this?
Here is some code:
HTML
<div class="circleBase type1">
<p class="hidetext">Lorem ipsum</p>
<hr size="10">
<strong class="gray hidetext">gdroel</strong>
</div>
<div class="circleBase overlay">
<p class="date">11/12/14</p>
</div>
and jQuery
$(document).ready(function(){
$('.overlay').hide();
$('.date').hide();
$(".circleBase.type1").mouseenter(function(){
$(".overlay").fadeIn("fast");
$('.date').show();
$('.hidetext').hide();
});
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$('.date').hide();
$('.hidetext').show();
});
});

Use $(this) to get current element reference and do like this:
$(".circleBase.type1").mouseenter(function(){
$(this).next(".overlay").fadeIn("fast");
$(this).next(".overlay").find('.date').show();
$(this).find('.hidetext').hide();
});
and:
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$(this).find('.date').hide();
$(this).prev(".circleBase").find('.hidetext').show();
});

usually when I want to target something specific you just give it an ID.
ID's play better in JavaScript than classes.
If you had a specific container, using the container as your starting point is a good route as well
$('#container').find('.something.type1').doSomething();
This is much more efficient for jquery, because it only searches .something.type1 inside of #container.

Well I'm not sure exactly what you're looking to do, but it looks like you want to replace content in some kind of circle with a hover text, but with a fade. To do that you'll have to add some CSS and it would be best to change your HTML structure too.
The HTML should look like this:
<div class="circleContainer">
<div class="circleBase">
<p>Lorem ipsum</p>
<hr>
<strong class="gray">gdroel</strong>
</div>
<div class="overlay" style="display: none;">
<p class="date">11/12/14</p>
</div>
</div>
so your js can look like this:
$(function(){
$(".circleContainer").mouseenter(function(){
$(this).find(".overlay")
$(this).find('.circleBase').hide();
});
$(".circleContainer").mouseleave(function(){
$(this).find('.circleBase').show();
$(this).find(".overlay").hide();
});
});
Here's a working solution that includes some CSS to make it nice. Try taking it out and running it, you'll see the problems right away.

Javascript dom selection of next element

This is roughly my setup:
<div class="wrapper">
<div class="first">
<a class="button" href="">click</a>
</div>
<div class="second">
<div class="third">
Stuff
<div>
</div>
</div>
Ok, so what I want to is this: when you click the a tag, the .third div should animate.
What I have so far is this:
button.click ->
third.animate
left: '+=100%'
The problem is, I have multiple of these wrappers on one page. So when I click the button, every '.third' div on the page animates. How can I select the right one and only that one?
Thanks!
Try this:
$('a').click(function(){
var third = $(this).closest('.wrapper').find('.third');
//use third variable to animate
});
You can use closest or parents.
If you want only one div to animate, assign an id to the div and animate only that one by$("#third").animate("left", "100%");

Clone Div into another DIV

I am trying to clone a DIV to prevent data reputation; this is a frequent thing I want to do over various pages so I don't want to make bug structural changes.
I would like to Clone mApageLeft with the class maContent, and all of its inner div's and content into another div named cloneContent.
I have looked at other examples of Clone, and my attempt does not show anything. Thanks in advance for any help.
<div>
<div>
<div>
<div id="mApageLeft" name="mApageLeft" class="maContent">
<div> header and some text here
</div>
<div> text and image here
</div>
<div> text and another image here
</div>
</div>
</div>
</div>
</div>
<div id="mobileArea">
<div id="mobileMainArea">
headers, links and sme text
<div name="cloneContent" id="cloneContent" class="maContent"></div>
<script>
$(function(){
var $mainAreaClone = $('#mApageLeft').clone();
$('#cloneContent').html($mainAreaClone);
});
</script>
</div>
</div>
Your code works fine when I test it on fiddle. Even after that, if you wanna try something else, you can try append() instead of html() function. Usually when you clone, you want to append the cloned object, you don't want to put is as inner HTML. However, that will also work.

Trying to traverse the DOM so unique video will play when certain div is clicked

So, I have a requirement for dynamically generated content blocks on a page. These blocks have a thumbnail and when it is clicked, it should open a modal, and display an unique overlay window, as well as as the unique associated video.
I am trying to write some generic JavaScript that will traverse the DOM tree properly, so that when any particular thumbnail is clicked, a modal, the associated overlay, and the associated video will open.
Here is an example of what I have now (there are many of these, dynamically added):
<div class="block">
<div class="thumbnail">
//Thumbnail image
</div>
<p>Video Description</p>
<div class="window hide">
<div class="video hide">
//Video content
</div>
</div>
</div>
<div id="modal" class="hide"></div>
and after attempting to do a bunch of different things, I ended up trying to do something like this for the JavaScript, which doesn't work:
$(".thumbnail").on("click",function(){
$("#modal").removeClass("hide").addClass("show");
$(this).closest(".window").removeClass("hide").addClass("show");
$(this).closest(".video").removeClass("hide").addClass("show");
});
CSS is very basic:
.hide { display: none; }
.show { display: block; }
Trying to make the click function generic as possible so it would work on any .thumbnail that was clicked. I've also interchanged find(".window") and children(".window") but nothing happens. Any ideas on what I'm doing wrong? Thanks!
Depending on what you actually want your classes to be, I'd use this code:
$(".thumbnail").on("click", function () {
var $block = $(this).closest(".block");
$block.find(".window, .video").add("#modal").removeClass("hide").addClass("show");
});
DEMO: http://jsfiddle.net/gLMSF/ (using different, yet similar code)
It actually finds the right elements, based on the clicked .thumbnail. It finds its containing .block element, then looks at its descendants to find the .window and .video elements.
If you actually want to include . in your attributes, you need to escape them for jQuery selection.
As for styling, you should probably just have the styling be display: block; by default, and then toggle the hide class. It's less work, and makes more sense logically.
You have a huge issue with your class names in HTML:
<div class=".block">
it should be
<div class="block">
Your modal is the only one that has the class properly named. Your DOM traversals will not work because they are looking for "block" but it's called ".block"
So fix it all to this and you should find more success:
<div class="block">
<div class="thumbnail">
//Thumbnail image
</div>
<p>Video Description</p>
<div class="window hide">
<div class="video hide">
//Video content
</div>
</div>
</div>
<div id="modal" class="hide"></div>
Your code won't work because your selectors have periods (.) in your classes if that's actually what you want, you should try it like this:
$(".\\.thumbnail").on("click",function(){
$("#modal").removeClass("hide").addClass("show");
$(this).closest("\\.window").removeClass("hide").addClass("show");
$(this).closest("\\.video").removeClass("hide").addClass("show");
});
Otherwise just try removing the periods from the classes...
Also, you're using .closest() incorrectly, as it looks up through ancestors in the DOM tree...
You should change your code to:
$(".\\.thumbnail").on("click",function(){
$(this).next("\\.window").children(".video")
.addBack().add("#modal").removeClass("hide").addClass("show");
});

Adding Additional Div breaks Existing Jquery Code

I have a very simple div with an image inside:
<div class="stack4">
<img src="images/002m.jpg" width=200>
</div>
And a very simple Jquery function for when you hover over the image:
$(function () {
$('.stack4>img').hover(function(){
prompt('hello');
});
});
This all works fine. However, I'm trying to add additional content to the page, and so put the following HTML directly after the end of the first div:
<div id="menucontainer" class="menuContainer">
<div id="menu" class="menuContent">
<img src="images/003m.jpg" />
<img src="images/004m.jpg" />
</div>
</div>
After I add this, the jquery prompt no longer works. Why would adding anothing div break my existing javascript command like that?
There has to be a script error in the page that is causing a failure. Or there is a very slight chance that your new html in some way introduces an invisible element that covers your stack4 image. If you can provide a link somebody could debug it for you.
It breaks because the selector no longer matches any elements (because the class selector .stack4 does no longer match any element).
<div id="menucontainer" class="menuContainer">
<div id="menu" class="menuContent">
<img src="images/003m.jpg" />
<img src="images/004m.jpg" />
</div>
</div>
$(function () {
$('.stack4>img').hover(function(){
prompt('hello');
});
});
If you look at your javascript, it will:
match any child image of an element with class name stack4
Add a hover listener to each image
Display a prompt on hover.
IF you look at your updated DOM structure, class stack4 no longer exists. To make it work again, you have to replace this selector with your new equivalent, which would be the div with id=menu and class=menuContent.
Now, depending on your needs, you can target either #menu>img or .menuContent>img. If you go with the first one, the javascript fragment will only work for a single menu, with the id of menu. However, if you choose the second approach, any content with the class menuContent will have this functionality. So I'd go with:
$(function () {
$('.menuContent>img').hover(function(){
prompt('hello');
});
});

jQuery: get a reference to a specific element without using id

I'm tinkering a bit with jquery to show a hidden div when a link is clicked. This should be fairly simple, but there's a flaw to it in this case. I have the following markup:
<div class="first-row">
<div class="week">
<p>Uge 2</p>
<p>(08-01-11)</p>
</div>
<div class="destination">
<p>Les Menuires</p>
<p>(Frankrig)</p>
</div>
<div class="days">4</div>
<div class="transport">Bil</div>
<div class="lift-card">3 dage</div>
<div class="accommodation">
<p><a class="show-info" href="#">Hotel Christelles (halvpension)</a></p>
<p>4-pers. værelse m. bad/toilet</p>
</div>
<div class="order">
<p>2149,-</p>
<p class="old-price">2249,-</p>
</div>
<div class="hotel-info">
<!-- The div I want to display on click -->
</div>
</div>
When I click the "show-info" link I want the "hotel-info" div to display.
My backend devs don't want me to use ids (don't ask me why..) and the above markup is used over and over again to display data. Therefore I need to be able to access the "hotel-info" div in the "first-row" div where the link is clicked.
I've tried to do something like:
$(document).ready(function() {
$('.show-info').click(function() {
var parentElement = $(this).parent().parent();
var lastElementOfParent = parentElement.find(".show-hotel");
lastElementOfParent.show();
});
});
But without a result :-/ Is this possible at all?
Any help is greatly appreciated!
Thanks a lot in advance!
Try this:
$('.show-info').click(function() {
$(this).closest('.accommodation').siblings('.hotel-info').show();
});
Even better imo, as it would be independent from where the link is in a row, if every "row div" has the same class (I assume only the first one has class first-row), you can do:
$(this).closest('.row-class').find('.hotel-info').show();
Reference: .closest, .siblings
Explanation why your code does not work:
$(this).parent().parent();
gives you the div with class .accommodation and this one has no descendant with class .hotel-info.
It is not a good idea to use this kind of traversal for more than one level anyway. If the structure is changed a bit, your code will break. Always try to use methods that won't break on structure changes.
You're right in not using an ID element to find the DIV you want :)
Use closest and nextAll
Live demo here : http://jsfiddle.net/jomanlk/xTWzn/
$('.show-info').click(function(){
$(this).closest('.accommodation').nextAll('.hotel-info').toggle();
});
