stopPropagation() div inside div onmouseover - javascript

I want to put a div inside another div, and when the user put the mouse on the parent div the two divs show up.
The problem is that when I put the mouse over the parent div the two divs show up but when I move the mouse over the child div the show() function execute it self again, how can I stop that?
HTML code:
<div id="parent" onmouseover="show(this)">
<div id="child"></div>
</div>
JavaScript code:
function show(element) {
setTimeout(function () {
opacity(element)
}, 100);
}
function opacity(element) {
element.style.opacity = "1"
}

This can and should be solved using CSS only, without JavaScript.
Example
<div id="parent">
Parent Text
<div id="child">Child Text</div>
</div>
#parent {
opacity: .2;
transition: .1s opacity;
}
#parent:hover {
opacity: 1;
}

using jquery :
$('#child').hover(function(e){e.stopPropagation();});
with normal js :

How to set transition when button is clicked and it changes from display 'none' to display 'block'

I am trying to make it so, that when a button is clicked like a toggle, the texts and everything below it move smoothly below it instead of suddenly moving it. An example of this is bootstrap navbar hamburger menu. When the menu is clicked in mobile view, the rest of the items under it move in a smooth manner to make room for the navbar items.
Here are my codes in the snippet.
let box = document.querySelector("#box");
let seconddiv = document.querySelector("#seconddiv");
box.addEventListener("click", myfunc);
function myfunc() {
if(seconddiv.style.display == "none") {
seconddiv.style.display = "block";
}
else {
seconddiv.style.display = "none"
}
}
#box {
height: 50px;
width: 50px;
background-color: red
}
#seconddiv {
display: none;
}
<div id="box">
</div>
<div id="seconddiv">
<p>whats up</p>
<p>whats up</p>
<p>whats up</p>
<p>whats up</p>
<p>whats up</p>
</div>
<p>hello</p>
When I click the red box, the "hello" text moves instantly when the "seconddiv" is set to display. Is it possible to move "hello" smoothly like in bootstrap?
You can use jQuery for this purpose. jQuery can handle better and in easy way.
Please include jQuery file for following jQuery code:
$('#box').click(function(){
$('#seconddiv').slideToggle();
});
If you want more slow speed for displaying and hiding div on click, then pass "slow" parameter in slideToggle function.
$('#seconddiv').slideToggle("slow");
display:none is not handled with transitions. But you can add a class to the button with javascript on click. And then give the button height:30px when it has class '.clicked'
#seconddiv {
height: 0;
transition: height 0.5s
}
#seconddiv.clicked{
height: 30px;
}
You can work with width or opacity too instead of height, but the difference with opacity is that the element will still use the space even when set to opacity:0

How to use JQuery to detect Mouseover and add animation on dynamic item

I have a series of div's that get loaded dynamically. There ID is set when the page loads, and they all have the same class of "pp-post". When the user hovers over an item with class="pp-post" the 'p' items within that become visible.
I want to add a different animation for each of these 'p' tags when they become visible.
I have minimal experience with JQuery so I am wondering how I can detect which "pp-post" item is hovered and apply the animations to the 'p' tags.
As for the animations not sure yet what to use but it could be JQuery animations or maybe use animations.css and add a class to the p tags when visible.
HTML:
<div id="{post_id}" class="pp-post">
<div id="{post_id}" class="pp-post-item">
<p id="{post_id}" class="pp-post-title"></p>
<p id="{post_id}" class="pp-arrow-down"></p>
</div>
</div>
CSS:
.pp-post-title {
visibility: hidden;
}
.pp-arrow-down {
visibility: hidden;
}
.pp-post-item:hover > p {
visibility: visible;
}
how I can detect which "pp-post" item is hovered and apply the animations to the 'p' tags
You can use $(this) to get the hovered pp-post.
The code will look like
$('.pp-post').hover(function(){
$(this).animate({
//animation code
});
});
To make p tag visible,
$('pp-post').hover(function(){
$(this).find('p').animate({
//animation code
});
});
Instead of animation function, you can also use certain specific functions like fadeIn
Sample snippet
$(document).ready(function() {
$('.pp-post').hover(function() {
$(this).find('p').fadeIn(2000);
});
});
.pp-post p {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="pp-post">Hover
<p>Sample1</p>
</div>
<div class="pp-post">Hover
<p>Sample1</p>
</div>
<div class="pp-post">Hover
<p>Sample1</p>
</div>
<div class="pp-post">Hover
<p>Sample1</p>
</div>
<div class="pp-post">Hover
<p>Sample1</p>
</div>

On hover add / remove class - not always working

I'm implementing some animation by adding and removing classes to an element on mouseover and mouseout. I'm using this method as I found using CSS alone was not reliable; the animation would not complete if the mouse exited the element before the animation finished.
So I have the following code:
<div class="one flip-container">
<div class="flipper">
<div class="front">
<!-- front content -->
</div>
<div class="back">
<!-- back content -->
</div>
</div>
</div>
<script>
jQuery(".flip-container").hover(function () {
jQuery(this).addClass("hover");
},function () {
jQuery(this).delay(2000).queue(function(){
jQuery(this).removeClass("hover");
});
});
</script>
<style>
.flip-container.hover .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
</style>
This works but sometimes the class 'hover' is not removed, it stays, leaving the element in its animated state. Any idea how to make this more reliable?
Try using mouseenter and then set a timeout function to remove the class that way you wont be adding and removing classes except once each time the mouse enters the area. Also you may want to check to see if the area already has the class to avoid the function from being executed too many times like so:
jQuery(".flip-container").mouseenter(function () {
var el = jQuery(this);
if(!el.hasClass("hover")){
el.addClass("hover");
setTimeout(function(){
el.removeClass("hover");
}, 2000);
}
});

jQuery slideDown not functioning correctly

I wish to animate a div to make it appear and slide down with jQuery.
I have got my script to work where you hover over an image and another div slides in, should the user leave the mouse hover, the div will slide up and disappear.
Problem:
The first time i hover over the image, nothing happens. I have to leave my mouse and hover over it a second time for the effect to start working, I dont get why this is???
jQuery:
function show_action(){
$(function(){
$(".action").hide();
$(".logo").hover(
function(){ $(".action").slideDown(); },
function(){ $(".action").slideUp(); }
);
});
}
CSS:
#action_text{
display:none;
}
HTML:
<div class="center_container">
<div class="action" id="action_text"><span>Click To Upload</span></div>
<img src="images/logo.png" class="logo" onmouseover="show_action();">
</div>
No need to call .hide() on the .action element. Just give it display: none in your css, so that it will not show when the page loads. That way, you don't need the .stop() to clear the animation queue, and it also prevents a 'flicker' effect where your .action element will show up when the page loads for a brief moment until .hide() gets called.
$(document).ready(function() {
$('.logo').hover(
function() {
$(".action").slideDown();
},
function() {
$(".action").slideUp();
}
);
});
.action {
width: 100%;
background-color: red;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<span class="logo">LOGO</span>
</div>
<div class="action">
<span>Action</span>
</div>
I think you are calling function show_action as onhover="show_action() remove that and move the rest code outside function wrapping, otherwise the hover() event handler will only bind after the first hover. additionally use stop() to clear the animation queue
$(function() {
$(".action").hide();
$(".logo").hover(
function() {
$(".action").stop().slideDown();
},
function() {
$(".action").stop().slideUp();
}
);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class=logo>Hover here</div>
<div class=action>content<br>here</div>
Update : You can remove $(".action").hide(); by adding following css
.action {
display: none;
}

Targeting previous div in javascript or css

HTML code:
<div class="content">
<textarea> hello.png </textarea>
</div>
<div class="content-btn">
Click me
</div>
Javascript code:
$(".button").click(function() {
if ($(this).parent().previousSibling('.content').css('display') == 'none'){
$('.content').hide();
$(this).parent().previousSibling('.content').show();
}else {
$('.content').hide();
}
});
How would I go about only showing the textarea when 'Cick me' is clicked or hovered preferably in css but if not javascript. Thanks guys

As exercise you could do this effect in pure css (using :target pseudoclass and a long delay in a simple transition) if you add a close button just below the textarea
http://codepen.io/anon/pen/JYoMRK
<div class="content" id="text">
<textarea> hello.png </textarea><br />
Close
</div>
<div class="content-btn">
Open
</div>
CSS
#text {
overflow: hidden;
height: 0;
opacity: 0;
transition: opacity 0s 999999s;
}
#text:target {
opacity: 1;
height: auto;
transition-delay: 0s;
}
#text:target ~ div a.button { display: none; }
Anyway if you look for a straight jQuery approach, a simple toggle() is enough (you might have to hide the .content element via css depending on the initial condition of your textarea)
https://jsfiddle.net/uway5hhg/39/
$(".button").click(function() {
var content = $(this).parent().prev('.content');
content.toggle();
});
As far as I know there is no way to catch previous sibling in CSS.
But it works with jQuery, here is your slightly changed code:
$(".button").on('click', function() {
var ele = $(this),
par = ele.parent(),
sbl = par.prev();
if (sbl.css('display') == 'none'){
$('.content').hide();
sbl.show();
}else {
$('.content').hide();
}
});
Working example is here: https://jsfiddle.net/y0ab3n0L/
That should do it's job
JS:
$(".button").click(function() {
var contentBtn = $(this).parent(".content-btn");
var content = $(contentBtn).prev(".content");
var textarea = $(content).find("textarea");
$(textarea).toggle();
});
or event shorter:
$(".button").click(function() {
$(this).parent(".content-btn").prev(".content").find("textarea").toggle();
});

Hope this helps :)
Solution provided by Fabrizio is a good one if you want no javascript.
However you can also modify the DOM to have a similar effect.
<div class="content-wrapper">
<div class="content" id="text">
<textarea>hello.png</textarea>
</div>
Click me
</div>
CSS
.content {
display:none;
}
.content-wrapper:hover .content {
display:block;
}
.content-wrapper:hover .button {
display:none;
}
https://jsfiddle.net/2Lsszgqz/
There is no such CSS pseudo element - a.button:click, so only JS solution will work (without changing your HTML structure). You can also get to close of it using :focus CSS pseudo class. But you will lack to go up one level in CSS and then show the textarea. So, only solution left is using JS.
In your sample JS code you have used .previousSibling('.content') which is native JS, which you are calling on jQuery object, that's why it will not work. jQuery equivalent of this function is .prev('.content')
Correct Syntax would be -
$(".button").click(function() {
if ($(this).parent().prev('.content').css('display') == 'none'){
$('.content').hide();
$(this).parent().prev('.content').show();
}else {
$('.content').hide();
}
});
