Adding preventDefault() and stopPropagation()

Adding preventDefault() and stopPropagation() - javascript

I am new in coding in general, most especially javascript.
I made a flip div effect. But I noticed that when clicking one .button to trigger the flip effect, all the other divs that are similar in a page are also triggered. So I am trying to add both .preventDefault() and .stopPropagation() when flipping a div, so far its a big FAIL
As a starter, I came up with this code..
$('.insidecontent .button').click(function () {
$('.insidecontent').addClass('flipped');
$('.insidecontent').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$('.insidecontent').removeClass('flipped');
$('.insidecontent').addClass('unflipped');
});
Demo here: http://jsfiddle.net/uriri/ke7kqvvk/3/
A friend of mine suggested that I should use .parents() on the current target inside the .click() function. But after reading the jQuery documentation, I am totally lost!

You don't need to stop click event or prevent default. You just need to flip right element. Right not you are adding/removing classes to/from all .insidecontent, while you need to select only parent element of the clicked button:
$('.insidecontent .button').click(function () {
$(this).closest('.insidecontent').addClass('flipped').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).closest('.insidecontent').removeClass('flipped').addClass('unflipped');
});
Demo: http://jsfiddle.net/ke7kqvvk/5/
Or shorter optimized version can be:
$('.insidecontent').find('.button, .button-c').click(function () {
$(this).closest('.insidecontent').toggleClass('flipped unflipped');
});
Demo: http://jsfiddle.net/ke7kqvvk/6/

preventDefault() and stopPropagation() won't help here. You need to use a selector that's more specific than all the elements with the same class.
$('.insidecontent .button').click(function () {
$(this).closest('.insidecontent').addClass('flipped').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).closest('.insidecontent').removeClass('flipped').addClass('unflipped');
});

Have you learned about the "this" keyword yet? In a JQuery click handler, $(this) refers to the element that the handler is called on. So, if you put removeClass and addClass methods on $(this) it will only affect that one element. You can traverse using this too... so your code would look like this:
$('.insidecontent .button').click(function () {
$(this).parent().find('.insidecontent').addClass('flipped');
$(this).parent().find('.insidecontent').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).parent().find('.insidecontent').removeClass('flipped');
$(this).parent().find('.insidecontent').addClass('unflipped');
});
you may not even need the find method in your case, but it is better to be explicit.

Jquery Click this or that and toggle class

Im stuck on toggeling a class when there is a click event on either the parent or child item. It is about a navigation menu that can be clickable on the entire bar or just the icon.
Current situation: (according to the fiddle)
When you click on the red block, the class is-active will be toggled on the .hamburger-menu class. Allowing the icon to transition via CSS.
But when you click on the hamburger icon it does not toggle the class.
How can the class is-active be toggled when there is a click event on either the #menuContainer or the .hamburger-menu div?
jQuery(function($) {
$(document).ready(function() {
$("#menuContainer, .hamburger-menu").click(function() {
$(".hamburger-menu").toggleClass("is-active");
});
});
});
.menu_container {
display: block;
position: absolute;
left: 45%;
top: 45%;
width: 100px;
height: 100px;
background-color: red;
cursor: pointer;
}
.menu_container .menu-active {
background-color: blue;
}
.hamburger-menu {
display: inline-block;
position: absolute;
left: 35%;
top: 45%;
margin: 0 auto;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu:hover {
cursor: pointer;
}
.hamburger-menu span {
display: block;
width: 40px;
max-width: 100%;
height: 3px;
background-color: #414042;
margin-bottom: 5px;
border-radius: 5px;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu.is-active span:nth-child(2) {
display: none;
}
.hamburger-menu.is-active span:nth-child(1) {
-webkit-transform: translateY(4.5px) rotate(45deg);
-ms-transform: translateY(4.5px) rotate(45deg);
-o-transform: translateY(4.5px) rotate(45deg);
transform: translateY(4.5px) rotate(45deg);
}
.hamburger-menu.is-active span:nth-child(3) {
-webkit-transform: translateY(-4.5px) rotate(-45deg);
-ms-transform: translateY(-4.5px) rotate(-45deg);
-o-transform: translateY(-4.5px) rotate(-45deg);
transform: translateY(-4.5px) rotate(-45deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="menuContainer" class="menu-trigger menu_container">
<div class="hamburger-menu">
<span></span>
<span></span>
<span></span>
</div>
</div>

The issue is because you've added the click event handler to two elements, #menuContainer and .hamburger-menu. The latter is a child of the former, so when you click that the handler fires twice. This means that the class is toggled on, then immediately off again (or vice versa)
To fix this issue, call stopPropagation() on the event. This stops the event bubbling up the DOM and being handled twice.
jQuery(function($) { // Note you only need one document.ready handler here
$("#menuContainer, .hamburger-menu").click(function(e) {
e.stopPropagation();
$(".hamburger-menu").toggleClass("is-active");
});
});
.menu_container {
display: block;
position: absolute;
left: 45%;
top: 45%;
width: 100px;
height: 100px;
background-color: red;
cursor: pointer;
}
.menu_container .menu-active {
background-color: blue;
}
.hamburger-menu {
display: inline-block;
position: absolute;
left: 35%;
top: 45%;
margin: 0 auto;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu:hover {
cursor: pointer;
}
.hamburger-menu span {
display: block;
width: 40px;
max-width: 100%;
height: 3px;
background-color: #414042;
margin-bottom: 5px;
border-radius: 5px;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu.is-active span:nth-child(2) {
display: none;
}
.hamburger-menu.is-active span:nth-child(1) {
-webkit-transform: translateY(4.5px) rotate(45deg);
-ms-transform: translateY(4.5px) rotate(45deg);
-o-transform: translateY(4.5px) rotate(45deg);
transform: translateY(4.5px) rotate(45deg);
}
.hamburger-menu.is-active span:nth-child(3) {
-webkit-transform: translateY(-4.5px) rotate(-45deg);
-ms-transform: translateY(-4.5px) rotate(-45deg);
-o-transform: translateY(-4.5px) rotate(-45deg);
transform: translateY(-4.5px) rotate(-45deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

The problem is that the event is propagating up to the parent when you click on the hamburger menu causing the class to toggle twice and make it look like it's not working. To fix this, you need to add e.stopPropagation(); to the click function.
jQuery(function($) {
$(document).ready(function() {
$("#menuContainer, .hamburger-menu").click(function(e) {
$(".hamburger-menu").toggleClass("is-active");
e.stopPropagation();
});
});
});
.menu_container {
display: block;
position: absolute;
left: 45%;
top: 45%;
width: 100px;
height: 100px;
background-color: red;
cursor: pointer;
}
.menu_container .menu-active {
background-color: blue;
}
.hamburger-menu {
display: inline-block;
position: absolute;
left: 35%;
top: 45%;
margin: 0 auto;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu:hover {
cursor: pointer;
}
.hamburger-menu span {
display: block;
width: 40px;
max-width: 100%;
height: 3px;
background-color: #414042;
margin-bottom: 5px;
border-radius: 5px;
-webkit-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
.hamburger-menu.is-active span:nth-child(2) {
display: none;
}
.hamburger-menu.is-active span:nth-child(1) {
-webkit-transform: translateY(4.5px) rotate(45deg);
-ms-transform: translateY(4.5px) rotate(45deg);
-o-transform: translateY(4.5px) rotate(45deg);
transform: translateY(4.5px) rotate(45deg);
}
.hamburger-menu.is-active span:nth-child(3) {
-webkit-transform: translateY(-4.5px) rotate(-45deg);

-o-transform: translateY(-4.5px) rotate(-45deg);

Make hamburger menu fadeout work

I am doing a "hamburger" menu, responsive style, with a menu that will cover the page the viewer is at.
I got all HTML/CSS figured out, but I wanted to add fade in and fade out effects.
Fade in works with jquery code but the menu isn't fading out. Already tried some ideas that were on SO but none works.
Any help? Fiddle: https://jsfiddle.net/f19kz640/

Javascript/JQuery
$(document).ready(function(){
$('#nav-icon').click(function(){
$(this).toggleClass('open');
if($('#menu').css('opacity') == '0'){
$('#menu').css('opacity','1');
$('#menu').fadeIn(300).css('display','table');
}else{
$('#menu').css('opacity','0');
$('#menu').fadeOut(300).css('display','none');
}
});
});

You could easily simplify things a great deal:
$(document).ready(function(){
$('#nav-icon').click(function(){
$(this).toggleClass('open');
$('#menu').fadeToggle(300);
});
});
Updated Fiddle
There's no reason to play with opacity properties or display properties, it's all part of the jQuery fade() function, which you can merely toggle.

jquery combining multiple variables (elements set as vars)

I am trying to learn a bit of Javascript/JQuery for school and got stuck on something I don't quite understand.
Everything in my function "works" as I wanted it to, but it feels odd that I have to list each of my selectors on a different line in order to remove all classes from each.
I've tried .merge and .add as suggestions i read on other posts, but I couldn't make it work (possibly not implementing it right) and I was hoping someone can show me how to do it and maybe explain why something like this doesn't work:
$(menuWrapper, menuTrigger, menuIcon, contentWrapper).removeClass();
This is my entire function, along with it working(just desktop css) on jsFiddle
// JavaScript Document
function toggleNavSettings(swipeDirection) {
menuWrapper = $("#menu-wrapper");
menuIcon = $('#menu-icon');
menuTrigger = $("#menu-trigger-wrapper");
contentWrapper = $("#custom-wrapper");
if(menuWrapper.width() > 199){//if nav expanded
if($( document ).width() > 480){//if screen is not mobile
menuWrapper.removeClass();
menuTrigger.removeClass();
menuIcon.removeClass();
contentWrapper.removeClass();
menuWrapper.addClass("menu-collapsed");//collapse the emenu
menuTrigger.addClass("menu-trigger-wrapper-d-closed");//swing the trigger
menuIcon.addClass("open-d");
contentWrapper.addClass("closed-d");//collapse the content pane
}
else{//if screen is Mobile
menuWrapper.removeClass();
menuTrigger.removeClass();
menuIcon.removeClass();
contentWrapper.removeClass();
menuWrapper.addClass("menu-collapsed-m");//expand menu for desktop
menuTrigger.addClass("menu-trigger-wrapper-d-closed");//swing the trigger
menuIcon.addClass("open-d");
contentWrapper.addClass("closed-d");
}
}
else{//if NAV is collapsed
if($( document ).width() > 480){//if screen is not mobile
menuWrapper.removeClass();
menuTrigger.removeClass();
menuIcon.removeClass();
contentWrapper.removeClass();
menuWrapper.addClass("menu-expanded");//expand menu
contentWrapper.addClass("open-m");//expand the content pane
}
else{//if window screen is MOBILE
menuWrapper.removeClass();
menuTrigger.removeClass();
menuIcon.removeClass();
contentWrapper.removeClass();
menuWrapper.addClass("menu-expanded-m");//expand the menu
menuTrigger.addClass("menu-trigger-wrapper-m-open");//swing the trigger
menuIcon.addClass("open-m");
contentWrapper.addClass("open-d");//expand the content pane
}
}
}
$(document).ready(function() {
var menuTrigger = $("#menu-trigger-wrapper");
menuTrigger.click(function() {
toggleNavSettings(null);
});
});

Thanks in advance!

You could use something like this
$('#menu-wrapper, #menu-icon, #menu-trigger-wrapper, #custom-wrapper').removeClass();
EDIT
You can keep your variables and use following syntax object.selector to get the ID value. The only "messy" thing are the string commas.
$(menuWrapper.selector+","+ menuTrigger.selector+","+menuIcon.selector+","+ contentWrapper.selector).removeClass();

This is riding the line of a duplicate question to: How to combine two jQuery results
One slight difference is you'd have to pass each collection individually, eg:
var allMenuObjects = menuWrapper.add(menuIcon).add(menuTrigger).add(contentWrapper);
Hopefully this helps and I appreciate your efforts in understanding how to use jQuery efficiently. (eg without engaging the selector engine repeatedly)

Try the below code,
You can use toggleClass
Find more information about toggleClass
function toggleNavSettings(swipeDirection) {
menuWrapper = $("#menu-wrapper");
menuIcon = $('#menu-icon');
menuTrigger = $("#menu-trigger-wrapper");
contentWrapper = $("#custom-wrapper");
if ($(document).width() > 480) { //if screen is not mobile
menuWrapper.toggleClass("menu-collapsed");
menuTrigger.toggleClass("menu-trigger-wrapper-d-closed");
menuIcon.toggleClass("open-d");
contentWrapper.toggleClass("closed-d");
} else { //if screen is Mobile
menuWrapper.toggleClass("menu-collapsed-m");
menuTrigger.toggleClass("menu-trigger-wrapper-d-closed");
menuIcon.toggleClass("open-d");
contentWrapper.toggleClass("closed-d");
}
}
$(document).ready(function() {
var menuTrigger = $("#menu-trigger-wrapper");
menuTrigger.click(function() {
toggleNavSettings(null);
});
});

jquery button trigger css

i want to make a button which have jquery function can trigger the css which will flip the card.
i do not know Trigger , toggle or addClass to use. Help thanks !
I actually want it to automatically flip from num 1 to 10.
With looping , how is it going to achieve ?
html
<div class="panel" id="card2">
<div class="front card">
<img src="0.png">
</div>
<div class="back card">
<img src="2.png">
</div>
</div>
css
.panel {
width: 200px;
height: 300px;
margin: auto;
position: relative;
}
.card {
width: 100%;
height: 100%;
-o-transition: all .5s;
-ms-transition: all .5s;
-moz-transition: all .5s;
-webkit-transition: all .5s;
transition: all .2s;
-webkit-backface-visibility: hidden;
-ms-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;
position: absolute;
top: 0px;
left: 0px;
}
.front {
z-index: 2;
}
.back {
z-index: 1;
-webkit-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
transform: rotateY(-180deg);
}
.panel:hover .front, .togglefront {
z-index: 1;
-webkit-transform: rotateY(180deg);
-ms-transform: rotateY(180deg);
-moz-transform: rotateY(180deg);
transform: rotateY(180deg);
}
.panel:hover .back ,.toggleback{
z-index: 2;
-webkit-transform: rotateY(0deg);
-ms-transform: rotateY(0deg);
-moz-transform: rotateY(0deg);
transform: rotateY(0deg);
}

You could use jQuery UI's .switchClass() function to remove and add the specified class. Here is an example:
$("#flip").click(function() {
$(".card").each(function(index) {
if ($(this).hasClass("front")) {
$(this).switchClass("front", "back");
return;
}
if ($(this).hasClass("back")) {
$(this).switchClass("back", "front");
return;
}
});
});
.panel {
width: 200px;
height: 300px;
margin: auto;
position: relative;
}
.card {
width: 100%;
height: 100%;
-o-transition: all .5s;
-ms-transition: all .5s;
-moz-transition: all .5s;
-webkit-transition: all .5s;
transition: all .2s;
-webkit-backface-visibility: hidden;
-ms-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;
position: absolute;
left: 0px;
}
.front {
z-index: 2;
}
.back {
z-index: 1;
-webkit-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
transform: rotateY(-180deg);
}
.panel:hover .front,
.togglefront {
z-index: 1;
-webkit-transform: rotateY(180deg);
-ms-transform: rotateY(180deg);
-moz-transform: rotateY(180deg);
transform: rotateY(180deg);
}
.panel:hover .back,
.toggleback {
z-index: 2;
-webkit-transform: rotateY(0deg);
-ms-transform: rotateY(0deg);
-moz-transform: rotateY(0deg);
transform: rotateY(0deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js"></script>
<button type="button" id="flip">Flip!</button>
<div class="front card">
<img src="http://i.stack.imgur.com/lSjRc.jpg">
</div>
<div class="back card">
<img src="http://i.stack.imgur.com/j5qcg.jpg">
</div>
Or you just use the .removeClass() and .addClass() functions. Here is an example without jQuery UI:
$("#flip").click(function () {
$(".card").each(function (index) {
if ($(this).hasClass("front")) {
$(this).removeClass("front");
$(this).addClass("back");
return;
}
if ($(this).hasClass("back")) {
$(this).removeClass("back");
$(this).addClass("front");
return;
}
});
});

JQUERY
$('.btn').click(function() {
$('.front').addClass('front-flip');
$('.back').addClass('back-flip');
});
You'll need to create a <button> element, and assign an event handler to that button using the code above. Essentially you'll create two new classes front-flip and back-flip which mimic the same CSS that you're currently assigning on hover to flip the card/image over.
See working example here - should set you on the right path EXAMPLE

Example Fiddle
I'm not sure this is the right way to do that, but it's work and you can improve it :
HTML :
<div class="panel panel_1" id="card2">
<div class="front card">
<img src="http://fr.fordesigner.com/imguploads/Image/cjbc/zcool/png20080526/1211813364.png">
</div>
<div class="back card">
<img src="http://fr.fordesigner.com/imguploads/Image/cjbc/zcool/png20080526/1211808744.png">
</div>
</div>
<button id='flip_card'>Flip card</button>
CSS :
.panel {
width: 200px;
height: 300px;
margin: auto;
position: relative;
}
.card {
width: 100%;
height: 100%;
-o-transition: all .5s;
-ms-transition: all .5s;
-moz-transition: all .5s;
-webkit-transition: all .5s;
transition: all .2s;
-webkit-backface-visibility: hidden;
-ms-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;
position: absolute;
top: 0px;
left: 0px;
}
.front {
z-index: 2;
}
.back {
z-index: 1;
-webkit-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
transform: rotateY(-180deg);
}
JS :
//Flip card function
$('#flip_card').click(function(){
var card_id = 'card2';
if($('#'+card_id+' .front').css('z-index')==1)
flip_front(card_id);
else
flip_back(card_id);
});
//Flip back of card
flip_back = function(card_id){
$('#'+card_id+' .front').css({
"z-index": 1, "-webkit-transform": "rotateY(180deg)", "-ms-transform": "rotateY(180deg)", "-moz-transform": "rotateY(180deg)", "transform": "rotateY(180deg)"
});
$('#'+card_id+' .back').css({
"z-index": 2, "-webkit-transform": "rotateY(0deg)", "-ms-transform": "rotateY(0deg)", "-moz-transform": "rotateY(0deg)", "transform": "rotateY(0deg)"
});
}
//Flip front of card
flip_front = function(card_id){
$('#'+card_id+' .back').css({
"z-index": 1, "-webkit-transform": "rotateY(180deg)", "-ms-transform": "rotateY(180deg)", "-moz-transform": "rotateY(180deg)", "transform": "rotateY(180deg)"
});
$('#'+card_id+' .front').css({
"z-index": 2, "-webkit-transform": "rotateY(0deg)", "-ms-transform": "rotateY(0deg)", "-moz-transform": "rotateY(0deg)", "transform": "rotateY(0deg)"
});
}
Hope this helps.

Why are the CSS transforms not displayed?

I'm trying to make a navigation panel slide in on the click of a nav button in the main menu. Needless to say, it's not working. I've made this work before, so I'm not sure what's going on. Help?

Yes, I am using FontAwesome. :)

Your biggest issue that solves your original question is due to overflow: hidden; on .wrapper.
Here it is removed: DEMO. But that opens up a whole new world of problems. I advise you to go back and refactor your code.

Ctrl-Shift-Del so your browser will reload your css.
Note: If this happens to your users, try changing the link to your css in your header like this:
<link rel="stylesheet" href="css/main.css?v=2">
