Show hide info.event.extendedProps.description Jquery

I am trying to make info.event.extendedProps.description field show hide when I click event title in Fullcalendar list view. But it only works partly.
Example here.
I added this under eventDidMount and works for line 1,3,5,7 etc. But not 2,4,6,8 etc
//Initially hide all the item-content
$('.item-content').hide();
// Attach a click event to item-title
$('.item-title').on('click', function() {
//Find the next element having class item-content
$(this).next('.item-content').toggle();
});

Use off(), off() method removes event handlers that were attached with .on(), so its works.
In your case:
$('.item-title').off().on('click', function () {
//Find the next element having class item-content
$(this).next('.item-content').toggle();
});
Note: I tested your code with off() on your codepen and it's work.

Animate icon don't take his original position on toggle click

I have a accordion menu which have for each parent menu a icon, and this icon is animated with css transition and transform. I added a class with a if condition to the click event. The problem is that when I click for example on Menu1, the icon animation does very well, but if I click directly on Menu2, the menu2 dropdown appear but icon from the menu1 don't take his original position.
This problem applies to each icon in each menu/submenu, I thinks that I have a mistake in my code.
$(document).ready(function() {
// Icons effect
$('#mw_nav .toggle').click(function() {
if($(this).hasClass('rotate_close'))
{
$(this).addClass('rotate_open').removeClass('rotate_close');
}
else {
$(this).addClass('rotate_close').removeClass('rotate_open');
}
});
// Toggle Menu Items
$(function () {
$("#m_nav > ul ul").hide();
$('#m_nav .toggle').click(function (e) {
e.preventDefault();
e.stopPropagation();
var $parentli = $(this).closest('li');
$parentli.siblings('li').find('ul:visible').slideToggle(400);
$parentli.find('> ul').stop().slideToggle(400);
$(this).remove;
});
});
});
FIDDLE
Any help would be appreciated

There are 2 issues I see with your code. The first is a recommendation to NOT have $(function() { // your code }) inside of $(document).ready(). $(function() {}) is actually just shorthand for $(document).ready() so you are adding code you do not need.
The second is an issue with your logic.
$('#mw_nav .toggle') and $('#m_nav .toggle') click listeners are essentially adding a click listener on the same exact element, but both run different logic. When the $('#mw_nav .toggle') click listener is getting called it checks for a class to exist to decide what class it needs to remove and add. When $('#m_nav .toggle') click listener is getting called it calls a slideToggle function on the current nested <ul> regardless if another menu is opened or closed and there is no check in place of whether or not the rotate_open/rotate_close classes exist allowing for the classes to get swapped. There is no relation between the swapping of rotate_open/rotate_close classes and the logic that slideToggles <ul> up/down.
UPDATE
I have edited your code and made updates that will now work seen here: https://jsfiddle.net/vhfn0q5a/9/
I have added a class of .top_level to the top level items in your HTML. I use this as a way of differentiating the top level <li> from the sub menus. Next, at the end of the click event listener I check to see if the .toggle element clicked is a top level element, if so I target all top level elements that are not the current selected and make sure they have the .rotate_close class.
$(function() {}) shorthand reference

Use this code in your first click handler:
$('#mw_nav .toggle').click(function() {
$(this).toggleClass('rotate_close rotate_open');
if ($('#mw_nav .toggle').not(this).hasClass('rotate_open')) {
$('#mw_nav .toggle').not(this).removeClass('rotate_open').addClass('rotate_close');
}
});
I've updated your FIDDLE with an working example.
Cheers!

D3 remove click events from one element out of a selection

I have a class in D3 say: selectors and I need to remove the click event from the selection
d3.selectAll('.selectors').on('click',function(){
//Remove the currently clicked element from the selection.
});
Ive got two problems:
The removed element is supposed to be moved to a different part of the page and the I need the click event on it to be removed.
Also, would it be possible to reinsert the removed element into the selection on doing something else, like clicking on the removed element again?
Edit:
Found a solution for problem 1
d3.selectAll('.selectors').on('click',function(){
//Remove the currently clicked element from the selection.
d3.select(this).on('click',null);
});
Is this the right way? Or is there a more graceful method?
A Demo Fiddle

here is the updated jquery it will work for your case
$(document).ready(function(){
$(document).on('click','.selectors',function(e){
//$(document).off( 'click','.selectors');
if(e.target.onclick==null)
{
e.target.onclick=
function(){
void(0);
};
alert('test');
console.log('Hello');
}
});
});

For problem 1, the best method(as far as I know) is to redefine the click event in D3 itself:
d3.selectAll('.selectors').on('click',function(){
//Remove the currently clicked element from the selection.
d3.select(this).on('click',null);
});
For problem 2, however, once you turn a click event callback to null, the only way is to redefine the click event again, perhaps recursively:
function clickDefine() {
d3.selectAll('.selectors').on('click', function () {
//Remove the currently clicked element from the selection.
console.log('Hello')
d3.select(this).on('click', null);
setTimeout(function(){clickDefine();},1000)
});
}
This function makes the click event inactive for 1 second on click. And reactivates this again. I'm hoping this is an effective solution.

Disable doubleclick event for an element in Opera

Is there a way to disable (with CSS, JS or jQuery) double-click for a given element?
The problem with Opera is that it displays a menu when I click on an element too fast. Note that I know how to disable this for me. I'd like to be able to disable this for all user that use the script.
The buttons in question are "next"/"previous" buttons and I use input type image for them, but the same happens with "a".

It turended out I need this:
/**
Disable text selection by Chris Barr, of chris-barr.com
*/
$.fn.disableTextSelect = function() {
return this.each(function(){
if($.browser.mozilla){//Firefox
$(this).css('MozUserSelect','none');
}else if($.browser.msie){//IE
$(this).bind('selectstart',function(){return false;});
}else{//Opera, etc.
$(this).mousedown(function(){return false;});
}
});
}
And then I could disable text selection on my button elements like this:
$(function(){ $('input[type=image]').disableTextSelect(); });
And now I can click buttons fast as hell and all works fine :-).

You cannot have a click and dblclick event handler attached on the same element because when you dblclick both the events are going to be triggered. In order to make it work there are few work arounds.
This might help you
Need to cancel click/mouseup events when double-click event detected
Looking at your problem there is a simple solution. In the click event handler once it is clicked set a disabled attribute or some class name(disabled). In the handler before exectuing your code checck for this attribute or class name. If it exists then dont do anything. After sometime remove this attribtue or class name. Try this
$("selector").click(function(){
var $this = $(this);
if(!$this.hasClass("disabled")){
//Do you stuff here
$this.addClass("disabled");
setTimeout(function(){
$this.removeClass("disabled");
}, 200);
}
});

JavaScript would do that for you.
DOMElement.ondblclick = (function () {return false;})();

how to make the menu close if it is clicked out

i have an menu with some values and i got someting hidden and while click on more button it shows like google more menu... if it is clicked out it is not hiding till the more menu is clicked once again
More<small>▼</small><div class="more list" id="one" style="display:none">test <span style="color:#329">|</span> test1 <span style="color:#169">|</span> test4</div></div>
Script:
function toggle(one)
{
var o=document.getElementById(one);
o.style.display=(o.style.display=='none')?'block':'none';
}
how to make it close while the mosuse clicks on any other place other than the menus

Try using the onblur event.

I see you've tagged this with jQuery, if that is an option, you can clear up the link a bit, like this:
More<small>▼</small>
And use unobtrusive script combined with event bubbling to your advantage, like this:
$(function() {
$(".more_link").click(function(e) {
$(this).next(".more").toggle();
e.stopPropagation();
});​​
$(".more").click(function(e) {
e.stopPropagation();
});
$(document).click(function() {
$(".more").hide();
});​
});
You can test it out here, this only closes the menu if you clicked neither the menu of the toggle, e.g. clicking one of the test links will not close it. If you want it to, just remove the $(".more").click(function(e) { e.stopPropagation(); }); portion.
It uses event.stopPropagation() to stop the click from bubbling up to document, which if happens (and would if you clicked anything else) triggers its click handler, closing all the .more elements.

I wouldn't use onBlur because it's not a good accessibility approach (for example if the user is using tab to navigate the page).
Look at this solution instead:
jQuery click event for document but ignore a div

Typically, I let the event bubble up to the 'body' or 'html' doc and check if the target is what i want (and/or isn't contained within what i want). If the event target is not contained within your menu, then perform your desired operation (in this case, hide the div).
i.e.
jQuery(document).ready(function(){
jQuery("html").bind("click", function(evt){
var $target = jQuery(evt.target);
var shouldShowMenu = $target.hasClass("menu_toggle");
shouldShowMenu |= $target.parents(".menu_toggle, .more_list").length;
if(!shouldShowMenu)jQuery(".more_list").hide();
});
});
NOTE: your markup would needs to be extended such that the "more" href becomes has a class attribute, class="menu_toggle"
