Add a class with hover effect in jquery - javascript

I want creating a website with some small news on the start-page. I show only the pics and show the headline and a small sentence with an hover-effect. Unfortunately I have no experience with jQuery and my code doesn't work.
$(document).ready(function () {
$(this).removeClass("#news-container .newscontent")
});
$(document).ready(function () {
$("#news-container img").hover(function () {
$(this).addClass("#news-container .newscontent");
}, function () {
$(this).removeClass("#news-container .newscontent");
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

If you want to toggle some class or the visibility of some childs with jquery the dom stucture is key. Let's assume you got the following structure:
<div class="newscontent">
<img class="image" src="...">
<div class="text">Some text</div>
</div>
The following code registers for the hover event on every image within an element with a newcontent class. The image with the hover $(this) searches for the next element with a text class and toggles the visibility.
$('.newscontent img').hover(function(){
if ( $(this).next('.text').css('visibility') === 'visible' ){
$(this).next('.text').css('visibility', 'hidden');
}else{
$(this).next('.text').css('visibility', 'visible');
}
});

Child div affects parent div in css and triggers jquery method

I have parent div with class a "very-big-div" that nests another "container-div" that by its turn also nests another child divs. The very big div's made to act like a button and the div that come right after it is a container that appears when I click the very big div.
<div class="very-big">
<div class="container">
<!-- Some other more nested divs that has anchors and buttons -->
<div class="friend-request">
<div class="button-div">
<button class="accept">Trigger</button>
<button class="refuse">Trigger</button>
</div>
</div>
</div>
</div>
The problem is 2 things first: the css problem has not yet been solved
I assigned a hover pseudo class for the "very-big-div", and whenever I hover the "container-div" the hover properties(background-color) is applied to the "very-big-div". This is not what I intend to make, I want to only hover "very-big" div for the hover to apply.
.very-big{
background-color:green;
}
The second problem is : I have a jquery that deals with the container so it is toggled on/off by the "very-big-div"
$(document).ready(function(){
$("#container-div").hide();
$("#very-big-div").click(function(){
$("#container-div").toggle();
});
});
the container has both anchor and button tags whenever I click the an anchor or a button inside the container it is toggled to close itself, and that is not what I want, what I want is just when I only press the "very-big-div" the toggle is activated.
Same as #Jhecht has given the answer, I have just inherited his to mine.
You can stop propagation of the click of child element that trigger toggle by using target and excluding all the child elements of your .very-big container as:
$(".very-big").click(function(e) {
var target = $(e.target);
if (!target.is('.very-big *')) {
$(".container").toggle();
}
});
Code Snippet:
$(document).ready(function() {
$(".container").hide();
$(".very-big").click(function(e) {
var target = $(e.target);
if (!target.is('.very-big *')) {
$(".container").toggle();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="very-big">
Other Text
<div class="container">
This is text to fill stuff out so I can click on it.
</div>
</div>
This works for me, but I am not sure if it is what you need.
Please add in the minimum HTML, CSS, and Javascript needed to fully recreate the error you are seeing.
$(document).ready(function() {
$(".container").hide();
$(".very-big").click(function(e) {
console.log(e);
var current = $(e.toElement);
if (current.is('.container')) {
e.stopPropagation();
return false;
}
$('.container').toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="very-big">
Other Text
<div class="container">
This is text to fill stuff out so I can click on it.
</div>
</div>

jquery detect class and add css to div

This is an example of a scenario I have got:
<div id="portfolio">
<a class="show-project" href="#">
<!-- some content here -->
</a>
<div class="scrollable">
<!-- full height container with scroll -->
</div>
</div>
When link is clicked, additional class is added to "scrollable move-left".
I would like to detect when it is added and replace css "overflow-y: auto;" with "overflow-y: hidden;"
I am trying to achieve this with:
<script>
$(document).ready(function () {
$("#portfolio .show-project").click(function(){
if ($("#portfolio .scrollable").hasClass("move-left")) {
$("#portfolio").css("overflow-y", "hidden");
} else {
$("#portfolio").css("overflow-y", "auto");
}
});
});
</script>
Could you advice me how to fix this please?
Very appreciated!
You can use jQuery toggleClass and hasClass in order to toggle the class on the element and change the overflow-y attribute accordingly.
Ref:
Add or remove one or more classes from each element in
the set of matched elements, depending on either the class's presence
or the value of the state argument.
Code:
$(document).ready(function () {
$("#portfolio .show-project").click(function () {
$("#portfolio .scrollable").toggleClass('move-left');
var overflow;
($("#portfolio .scrollable").hasClass("move-left")) ? overflow = 'hidden' : overflow = 'auto';
$("#portfolio").css("overflow-y", overflow);
});
});

Trying to build a gallery, how to fade out currently displayed div and fade in the next one?

I'm currently working on a new personal portfolio site using very basic html/css/jquery code. I'm trying to build my own gallery to display my work (instead of using an already existing one like lightbox) but I've run into an annoying issue: I've tried to make the "forward-button" display the immediate following div but instead it fades in all the following divs. Here's my (condensed) code:
HTML:
<!--navigation buttons for gallery-->
<a id="back-button"><img src="image.png" /></a>
<a id="forward-button"><img src="image.png"/></a>
<!--gallery begins here-->
<div id="gallery">
<div id="first-div" class="work-display">
<img src="images/albumust-display.png" class="work-image" />
<div class="caption" id="wd1c">
<p class="caption-text">caption</p>
</div>
</div>
<div id="second-div" class="work-display">
<img src="images/ce-display.png" class="work-image" />
<div class="caption">
<p class="caption-text">caption</p>
</div>
</div>
<div id="third-div" class="work-display">
<img src="images/display.png" class="work-image" />
<div class="caption">
<p class="caption-text">caption</p>
</div>
</div>
CSS (all divs inside gallery are hidden by default):
.work-display {
display:none;
position:absolute;
}
What I'm trying to do with Jquery is that everytime someone opens a thumbnail, give the corresponding div that displays the image on full size a "true" state of "active" and then fade in, like this:
$( "#thumb-1" ).click(function(){
$( "#first-div" ).prop("active",true);
$( "#first-div" ).fadeIn();
});
all divs originally have a state of "active" = false:
$( "#gallery" ).children("div").prop("active",false);
then this is what I've tried to do with the "forward-button":
$("#forward-button").click(function () {
$("#gallery").find( $("div").prop("active",true) )
.prop("active",false)
.fadeOut()
.next().fadeIn();
$(".caption").fadeIn();
});
But then what it does is that instead of fading in only the next div, it fades all the divs that come after. what am I doing wrong?
I'm very new to Javascript/Jquery so probably this isn't the smartest way to go about this, if you have a simpler solution, do tell me.
I couldn't test it properly, because I don't have the whole code (and the images either). But this should do the trick:
$(function () {
$("#gallery div").attr("active", false);
$("#thumb-1").click(function () {
$("#first-div").attr("active", true).fadeIn();
});
$("#forward-button").click(function () {
$("#gallery div[active=true]:first")
.attr("active", false)
.fadeOut()
.next()
.attr("active", true)
.fadeIn();
});
$("#back-button").click(function () {
$("#gallery div[active=true]:first")
.attr("active", false)
.fadeOut()
.prev()
.attr("active", true)
.fadeIn();
});
});
Kind of demo: http://jsfiddle.net/W8VLh/13/
Just in case you have a reason to use 'active' properties instead of classes:
$("#forward-button").click(function () {
$("#gallery").find( "div[active='true']")
.prop("active",false)
.fadeOut()
.next().fadeIn().prop("active",true);
$(".caption").fadeIn();
});

JQuery does not hide div if p element is before it?

I am trying to make use of a JQuery snippet to hide some content on SharePoint. It works without the <p> element, but SharePoint has a lot of stuff in between the div so I think that's why it's not working.
JQuery:
jQuery(document).ready(function() {
jQuery(".ms-wpcontentdivspace").hide();
//toggle the componenet with class msg_body
jQuery(".ms-webpart-chrome-title").click(function(e)
{
e.preventDefault();
jQuery(this).next("div.ms-wpcontentdivspace").slideToggle(200);
});
});
Here's the working code:
<div class="ms-webpart-chrome-title"><h2><span>Hello</span> </h2></div>
<div class="ms-wpcontentdivspace">Hi there. I am hidden</div>
<div class="ms-webpart-chrome-title"><h2>Another title</h2></div>
<div class="ms-wpcontentdivspace">More hidden stuff</div>
Here's the code that doesn't:
<div class="ms-webpart-chrome-title"><h2><span>Hello</span></h2></div>
<p>some text</p>
<div class="ms-wpcontentdivspace">Hi there. I am hidden</div>
<div class="ms-webpart-chrome-title"><h2>Another title</h2></div>
<div class="ms-wpcontentdivspace">More hidden stuff</div>
Here's a Jsfiddle. Thanks!
The jQuery version used 1.3.x is pretty old, anyway try
jQuery(document).ready(function () {
jQuery(".ms-wpcontentdivspace").hide();
//toggle the componenet with class msg_body
jQuery(".ms-webpart-chrome-title").click(function (e) {
e.preventDefault();
jQuery(this).nextAll("div.ms-wpcontentdivspace").eq(0).slideToggle(200);
});
});
Demo: Fiddle
$.next() only gets the immediately following sibling, so you will want to use $.nextAll()
jQuery(document).ready(function() {
jQuery(".ms-wpcontentdivspace").hide();
//toggle the componenet with class msg_body
jQuery(".ms-webpart-chrome-title").click(function(e)
{
e.preventDefault();
jQuery(this).nextAll("div.ms-wpcontentdivspace").eq(0).slideToggle(200);
});
});

How to implement a blinds toggle effect with jQuery

I'm trying to write a "blinds" function that would close a DIV in a display:none mode. The unseen DIV is inside a wider DIV, containing the blind trigger.
This:
$(document).ready(function () {
$("#toggle_blind").click(function () {
$(this).toggle("fast");
});
});
Well, this blinds the button. How can I add a DIV to $this? Something like:
<div id="blind" class="wider_div">
<h3 id="closeButton">Close</h3>
<div style="display:none;" id="closeThis">
<p>some text</p>
</div>
</div>
How do I make the Close Button on H3 to close/open the CloseButton DIV on each click?
The div is the next sibling of the h3 so you can use .next()
E.g
$('#closeButton').click( function(){
$(this).next().toggle();
});
Reference the div directly, you may put something else in between it and the h3.
$(document).ready(function()
{
$("#closeButton").click(function()
{
$("#closeThis").toggle("fast");
});
});
