Hover CSS with JQuery

I want to edit the rendering of an element when hovering. To achieve this, I created a button and I want the first click to set the hover rendering and the second click to reset the hover rendering. Currently, the hover style appears even when I'm not on the div:
$("#editer-script").click(function() {
var clicks = $(this).data('clicks');
if (clicks) {
$('.contenu-editable').mouseover(function(){
$('.contenu-editable').css("background-color", "transparent");
$('.contenu-editable .fa.fa-pencil').css("display", "none");
});
$("#editer-script").text('Rendre éditable');
} else {
$('.contenu-editable').mouseover(function(){
$('.contenu-editable').css("background-color", "#f4f6f9");
$('.contenu-editable .fa.fa-pencil').css("display", "inline-block");
});
$("#editer-script").text('Ne pas rendre éditable');
}
$(this).data("clicks", !clicks);
});
Thank you in advance for your help.

I would use two different css classes. One default and one for the change of the hover effects. And then just toggle the second class on click of the button element.
It's mutch easier than try to do it your way and it could be easily changed and extended just in css. No need to touch the script in the future.
$("#editer-script").click(function() {
var clicks = $(this).data('clicks');
$('.contenu-editable').toggleClass('special', !clicks);
$("#editer-script").text(clicks ? 'Rendre éditable' : 'Ne pas rendre éditable');
$(this).data("clicks", !clicks);
});
.contenu-editable:hover {
background-color: transparent;
}
.contenu-editable:hover .fa.fa-pencil {
display: none;
}
.contenu-editable.special:hover {
background-color: #f4f6f9;
}
.contenu-editable.special:hover .fa.fa-pencil {
display: inline-block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="editer-script">Rendre éditable</button>
<div class="contenu-editable">
<i class="fa fa-pencil">pencil</i>

Add & remove classes with fewer lines of code

I'm trying to learn how to shorten my jQuery code. Any suggestions or tips would be awesome:
jQuery(document).ready(function($){
$('#checkout_timeline #timeline-4').click(function() {
if ($('#checkout_timeline #timeline-4').hasClass('active')) {
$('#checkout-payment-container').addClass('cpc-visible');
}
});
$('#checkout_timeline #timeline-1, #checkout_timeline #timeline-2, #checkout_timeline #timeline-3').click(function() {
$('#checkout-payment-container').removeClass('cpc-visible');
});
});
To avoid clutter, please find the working version here:
My JSFiddle Code
I know I can use .show() and .hide() but due to other CSS considerations I want to apply .cpc-visible.

There are a handful of things you can improve here. First, you're over-specifying. Ids are unique. No need to select #checkout_timeline #timeline-4 when just #timeline-4 will do. But why even have ids for each li? You can reference them by number using the :nth-child(n) selector. Or better yet, you've already given them application-specific class names like billing, shipment, and payment. Use those! Let's simplify the original content to:
<ul id="checkout_timeline">
<li class='billing'>Billing</li>
<li class='shipping'>Shipping</li>
<li class='confirm'>Confirm</li>
<li class='payment active'>Payment</li>
</ul>
<div id='checkout-payment-container' class='cpc-visible'>
This is the container to show and hide.
</div>
Notice I left the active class, and indeed further initialized the checkout
div with cpc-visible to mirror the payment-is-active condition. Usually I would keep HTML as simple as possible and put "starting positions" initialization in code. But "in for a penny, in for a pound." If we start with payment active, might as well see that decision through, and start the dependent div in a consistent state.
Now, revised JavaScript:
jQuery(document).ready(function($) {
$('#checkout_timeline li').click(function() {
// make clicked pane active, and the others not
$('#checkout_timeline li').removeClass('active');
$(this).addClass('active');
// show payment container only if payment pane active
var paymentActive = $(this).hasClass('payment');
$('#checkout-payment-container').toggleClass('cpc-visible', paymentActive);
});
});
This code is much less item-specific. It doesn't try to add separate click handlers for different tabs/panes. They all get the same handler, which makes a uniform set of decisions. First, that whichever pane is clicked, make it active and the others not active. It does this by removing all active classes, then putting active on just the currently selected pane. Second, it asks "is the current pane the payment pane?" And it uses the toggleClass API to set the cpc-visible class accordingly. Often such "set class based on a boolean condition" logic is simpler and more reliable than trying to pair appropriate addClass and removeClass calls.
And we're done. Here's a JSFiddle that shows this in action.

Try this : You can user jquery selector with timeline and active class to bind click event handler where you can add required class. Same selector but not having active class to remove class.
This will be useful when you add / remove elements and will be more flexible.
jQuery(document).ready(function($){
$('#checkout_timeline .timeline.active').click(function() {
$('#checkout-payment-container').addClass('cpc-visible');
});
$('#checkout_timeline .timeline:not(.active)').click(function() {
$('#checkout-payment-container').removeClass('cpc-visible');
});
});
JSFIddle

Here is one of the ways, you can shorten this code by using :not(). Also its better to use elements than to reference and get them via JQuery always.
jQuery(document).ready(function($) {
var showHideContainer = $('#checkout-payment-container');
$('#checkout_timeline .timeline.active').click(function() {
showHideContainer.addClass('cpc-visible');
});
$('#checkout_timeline .timeline:not(.payment)').click(function() {
showHideContainer.removeClass('cpc-visible');
});
});

try this code its working fine with fiddle
$('.timeline').click(function() {
if ($(this).hasClass('active') && $(this).attr("id") == "timeline-4")
$('#checkout-payment-container').addClass('cpc-visible');
else
$('#checkout-payment-container').removeClass('cpc-visible');
});

This would of been my approach cause you still have to add/remove the active class between each li.
jQuery(document).ready(function($) {
$('ul li').click(function() {
$('ul li.active').removeClass('active');
$(this).closest('li').addClass('active');
k();
});
var k = (function() {
return $('#timeline-4').hasClass('active') ? $('#checkout-payment-container').addClass('cpc-visible') : $('#checkout-payment-container').removeClass('cpc-visible');
});
});
#checkout-payment-container {
float: left;
display: none;
background: red;
color: white;
height: 300px;
width: 305px;
padding: 5px;
}
ul {
list-style: none;
width: 100%;
padding: 0 0 20px 0px;
}
li {
float: left;
padding: 5px 11px;
margin-right: 5px;
background: gray;
color: white;
cursor: pointer;
}
li.active {
background: black;
}
.cpc-visible {
display: block !important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="checkout_timeline">
<li id='timeline-1' class='timeline billing'>Billing</li>
<li id='timeline-2' class='timeline shipping'>Shipping</li>
<li id='timeline-3' class='timeline confirm'>Confirm</li>
<li id='timeline-4' class='timeline payment'>Payment</li>
</ul>
<div id='checkout-payment-container'>
This is the container to show and hide.
</div>

Your code look great, i would have written it the same.
bit sure how much it helps but if you like, you can use inline if like this:
$(document).ready(function(){
$('#B').click(function() { (!$('#B').hasClass('active')) ?
$('#A').addClass('active') : ''; });
$('#C').click(function() { $('#A').removeClass('active'); });
});

Click Propagation failing in Jquery

For part of the site I'm working on, I have a set of sidebars that can pull out. To have them hide when the users are done with them, I've set up a div with a click event (see below) so that whenever the user clicks somewhere outside of the sidebar, the sidebar closes. The problem that I'm running into, however, is that the click event handler is grabbing the event, running its method, and then the click event seems to stop. I've tried using return true and a few other things I've found around here and the internet, but the click event just seems to die.
$('.clickaway').click(function() {
$('body').removeClass(drawerClasses.join(' '));
return true;
});
EDIT: Here is a fiddle with an example: https://jsfiddle.net/2g7zehtn/1/
The goal is to have the drawer out and still be able to click the button to change the color of the text.

The issue is your .clickaway layer is sitting above everything that's interactive, such as your button. So clicking the button, you're actually clicking the layer.
One thing you could do is apply a higher stacking order for elements you want to interact with, above the .clickaway layer. For example, if we apply position: relative, like this:
.show-drawerHotkey .ColorButton {
position: relative;
}
The element will now be in a higher stacking order (since it comes after the clickaway, and we've applied no z-index to clickaway)
Here's a fiddle that demonstrates: https://jsfiddle.net/2g7zehtn/5/

Using this somewhat famous SO answer as a guide, you can bind to the $(document).mouseup(); event and determine whether certain "toggling" conditions apply:
[EDIT] - Example updated to illustrate clicking a link outside of the containing div.

var m = $('#menu');
var c = $('#menuContainer');
var i = $('#menuIcon');
i.click(function() {
m.toggle("slow");
});
$(document).mouseup(function(e) {
console.log(e.target); // <-- see what the target is...
if (!c.is(e.target) && c.has(e.target).length === 0) {
m.hide("slow");
}
});

How to toggle two images onClick

I'm making a collapsible treeView.
I made it all, I just need my + and - icons to toggle whenever they are clicked.
I did the part when I change an icon from + to -, on click, with jQuery with the following code:
$(this).attr('src','../images/expand.gif');
Problem is, I don't know how to make it go other way around, when i click on the node again :)

This should work:
<style>
.expand{
content:url("http://site.com/expand.gif");
}
.collapse{
content:url("http://site.com/collapse.gif");
}
</style>
<img class="expand">
<script>
//onclick code
$('img.expand').toggleClass('collapse');
</script>

Look for jquery function toggleClass :)
http://jsfiddle.net/Ceptu/
Html:
<div id="box">
Hello :D
</div>
Jquery:
$("#box").click(function () {
$(this).toggleClass("red");
});
Css:
#box {
width: 200px;
height: 200px;
background-color: blue;
}
.red {
background-color: red !important;
}
Remember that !important is realy important!!!
Lots of ways to do this :D

I wanted to do this without making classes. Inside your click event function, you could do something like this:
if($(this).attr('src') == '../images/collapse.gif')
$(this).attr('src', '../images/expand.gif');
else
$(this).attr('src', '../images/collapse.gif');

add plus as a default img src then define a minus-class to change the image source to minus image
$("selector_for_your_link").click(function () {
$(this).toggleClass("minus-class");
});

jQuery Drop Down Hover Menu

I'm new to jQuery, I was hoping you guys could help me. I'm trying to make a hover dropdown menu, but it's extremely buggy. Can you help me clean up my Javascript? Look at my code please.
http://jsdo.it/mretchin/4Ewk
It doesn't work on jsdo.it for whatever reason, but it works in Komodo Edit.
Try out the code yourself if you really want to, the problem is mainly the Javascript. Can you help me make it so that when the user hovers over img.menu_class, ul.file_menu drops down, and then, if I wanted, I could hover over #something in ul and it would drop out horizantally, not vertically.
Thanks for helping! I appreciate it!
Should I just give up and make it work in CSS?

You can do something like this:
$(document).ready(function() {
$(".hoverli").hover(
function() {
$('ul.file_menu').stop(true, true).slideDown('medium');
},
function() {
$('ul.file_menu').stop(true, true).slideUp('medium');
}
});
});
And here an example with sub-menus:
$(document).ready(function() {
$(".hoverli").hover(
function() {
$('ul.file_menu').slideDown('medium');
},
function() {
$('ul.file_menu').slideUp('medium');
}
);
$(".file_menu li").hover(
function() {
$(this).children("ul").slideDown('medium');
},
function() {
$(this).children("ul").slideUp('medium');
}
);
});

For anyone who finds this in the future Aram's answer can be shortened with .slideToggle() to handle both up and down.
Here's the modified fiddle
http://jsfiddle.net/4jxph/2009/
If you have a sub-menu set to display: none; it will trigger it also, so what you'll want to do is set it to block, then add something like this
var subMenu = $('li.hoverli > ul > li');
subMenu.hover(function () {
$(this).find("ul").slideToggle(200);
});
And place it right below your first slideToggle. Why don't I just show you?
$(document).ready(function () {
$(".hoverli").hover(function () {
$(this).find('ul').slideToggle('medium');
});
var subMenu = $('li.hoverli > ul > li');
subMenu.hover(function () {
$(this).find("ul").slideToggle(200);
});
});

Not sure if you care but you want to make sure that you run the .stop() method that way the animations dont build themselves up and run over and over. Here's an example
http://jsfiddle.net/4jxph/1335/
$(document).ready(function () {
$(".hoverli").hover(
function () {
$('ul.file_menu').stop(true, true).slideDown('medium');
},
function () {
$('ul.file_menu').stop(true,true).slideUp('medium');
}
);
});

Use the finish function in jQuery to prevent the bug where you rapidly hover your mouse over the menu and out of the menu. Finish is better than the stop function previously suggested.
$(document).ready(
function () {
$(".hoverli").hover(
function () {
$('ul.file_menu').finish().slideDown('medium');
},
function () {
$('ul.file_menu').finish().slideUp('medium');
}
);
});

Aram Mkrtchyan's answer was almost there for me. Problem with his was if you add anything below the menu then it gets all screwy. Here is an example of what I mean, I added a div below his menu:

I am submitting this updated answer using div instead of lists and list items (which I find much easier to work with, and way more flexible) and jQuery version 1.9.1

);

I know this is probably a bit late but just found this thread saw that your question above about things below the menu 'getting a bit screwy' was unanswered.
If you give your div with the class 'file menu' a position of absolute then it should cease to affect any elements ahead of it as you will have taken it out of the normal flow.

To get a select box to open on hover to the exact height required by its contents, figure out how many elements there are:
JavaScript
function DropList(idval) {
//
// fully opens a dropdown window for a select box on hover
//
var numOptgroups = document.getElementById(idval).getElementsByTagName('optgroup').length;
var numOptions = document.getElementById(idval).getElementsByTagName('option').length;
document.getElementById(idval).size = numOptgroups + numOptions;
}
HTML
<select class="selectpicker" id="heightMenu" onmouseover="DropList('heightMenu')" onmouseout="this.size=1;" size="1">
<option value="0">Any height</option>
etc.
</select>
