select elements by condition using jquery

I am having a ul with li and <i> tag as children. The code is as below
<li class="accordion put">
<span><i class="fa fa-plus-circle"></i></span><span style="padding-left:5px;font-size: 18px;">Topic-Heading</span>
<ul class="panel2" style="display: none;">
<li class="testing"><i class="fa fa-chevron-right"></i> section 1</li>
<li class="testing"><i class="fa fa-chevron-right"></i> section 2 </li>
<li class="testing"><i class="fa fa-chevron-right"></i> section 3</li>
<li class="testing"><i class="fa fa-chevron-right"></i> section 4 </li>
</ul>
</li>
I have the below jquery code to toggle the class on click on the li as shown below:
$(".put.accordion" ).click(function() {
$(this).children("ul").toggle("slow");
$(this).find("i").toggleClass("fa-plus-circle fa-minus-circle");
});
The above code is working fine when I click on the li tag but since I have mentioned find('i') both the i tags are changing. I need to toggle only the i element having the class as fa-plus-circle and to ignore the i with class fa-chevron-right.
Please let me know where I am going wrong.

If you want a class independent way of selecting the first <i>, you can use .first() to reduce the matched results to the first returned <i> only.
In your case you could replace this line:
$(this).find("i").toggleClass("fa-plus-circle fa-minus-circle");
With this:
$(this).find("i").first().toggleClass("fa-plus-circle fa-minus-circle");
A generic example:
$('body').on('click', function() {
console.log( $(this).find('i').first().text() )
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Click anywhere to return the contents of the first <code><i></code>.</p>
<i class="first">First</i>
<i class="second">Second</i>
<i class="third">Third</i>

You can use the same syntax in find() as with other jQuery selectors. Just specify the class:
$(".put.accordion" ).click(function() {
$(this).children("ul").toggle("slow");
$(this).find("i.fa-plus-circle i.fa-minus-circle").toggleClass("fa-plus-circle fa-minus-circle");
});

You can find with :
find("i[class=fa-plus-circle]")

Javascript code for Bootstrap Sidebar menu not working

I have a Sidebar / Menu that I am working with. It has been created with Bootstrap, DJango, and Javascript.
Basically, I am trying to write Javascript so that when on clicks on a menu-item, the background changes color (dark blue), the icon change color (light green / turquoise) and it gets a type of "wedge"
Below is an example of a menu-item that has been chosen (Dashboard) along with menu-items that have not been chosen (Security and Messages). The "wedge" has a red arrow pointing to it.
Here is the HTML code that is being used:
[... snip ...]
<div class="page-container">
<div class="page-sidebar-wrapper">
<div class="page-sidebar navbar-collapse collapse">
<ul class="page-sidebar-menu page-header-fixed page-sidebar-menu-hover-submenu "
data-keep-expanded="false" data-auto-scroll="true" data-slide-speed="200">
<li class="nav-item start active open">
<a href="{% url 'mainadmin:dashboard' %}" class="nav-link nav-toggle">
<i class="fa fa-tachometer"></i>
<span class="title">Dashboard</span>
<span class="selected"></span>
<span class="arrow open"></span>
</a>
</li>
<li class="nav-item ">
<a href="{% url 'mainadmin:security' %}" class="nav-link nav-toggle">
<i class="fa fa-users"></i>
<span class="title">Security</span>
<span class="arrow"></span>
</a>
</li>
<li class="nav-item ">
<a href="{% url 'mainadmin:in_progress' %}" class="nav-link nav-toggle">
<i class="fa fa-comment"></i>
<span class="title">Messages</span>
<span class="arrow"></span>
</a>
<ul class="sub-menu">
<li class="nav-item ">
<a href="{% url 'mainadmin:in_progress' %}" class="nav-link ">
<span class="title">List All Messages</span>
</a>
</li>
<li class="nav-item ">
<a href="{% url 'mainadmin:in_progress' %}" class="nav-link ">
<span class="title">List My Messages</span>
<span class="badge badge-danger"></span>
</a>
</li>
</ul>
</li>
[... snip ...]
Here is the Javascript code:
<script>
$(document).ready(function () {
$('.nav-item a').click(function(e) {
$('.nav-item a').removeClass('selected');
$('.nav-item a').removeClass('arrow');
$('.nav-item a').removeClass('open');
$('.nav-item a').removeClass('active');
alert("I have gotten in");
var $parent = $(this).parent();
$parent.addClass('selected');
$parent.addClass('arrow');
$parent.addClass('open');
$parent.addClass('active');
e.preventDefault();
});
});
</script>
I do get the alert message - but - what happens is :
-> the background of the chosen menu-item does change color - which is correct
--> The icon of the chosen menu-item changes color (to light blue / turquoise) - which is correct
-> the tick of the arrow does not take place for the chosen menu-item :(
-> the old chosen menu item does not "de-select"
What am I doing wrong?
TIA
Hi #Joe Lissner
Thanks so much for the response!
I had to add the following to get the "wedge" portion to work. It required span tags
// REFERENCE: https://stackoverflow.com/questions/2013710/add-span-tag-within-anchor-in-jquery
$(this).append('<span class="selected"></span>');
$(this).append('<span class="arrow open"></span>');
While this works when clicking on the main-menu item, I'm not so lucky when it comes to clicking on sub-menu items. As of now, I am pretty much new to Javascript.
How would one get the sub-menu items to work?
Also, when clicking on an item, it does not go to the page specified in "href="
How would can one make changes to the code so that when the menu-item is clicked, it would go to the page specified in "href="
Again, thanks for the response :-)

You are removing the classes from the a tags, not the .nav-item elements.
Try this:
$(document).ready(function () {
$('.nav-item a').click(function(e) {
e.preventDefault(); // best practice to have this first, if you remove this line then the link will function as expected.
var $parent = $(this).parent();
var $arrow = $parent.find('.arrow');
$('.nav-item').removeClass('selected arrow open active'); // simplified
$('.nav-item .arrow').removeClass('open');
$('.nav-item .selected').detach(); // remove the span that was there before
alert("I have gotten in");
$parent.addClass('open active'); // simplified
$arrow.addClass('open').before('<span class="selected" />')
});
});
Edit - Fixed the issue with the arrow

jQuery: how to select the exact element of the same class?

Not sure I've formulated my question well, hope the details will cover the issues.
So, I'm building an "artificial" full-height slide-like submenu, and I have an empty container there:
<section class="masking_sublevel">
</section>
Further, I have a bunch of ul elements in my HTML that are hidden by default in their containing section:
I'm updating the HTML part with a more complete piece:
<div id="sldbr_overlay" class="newully">
<section class="masking_sublevel">
</section>
<ul class="sidebar_bumenu">
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
Beauty <i class="fa fa-chevron-right bu_chevright"></i>
<i class="fa fa-chevron-down bu_chevdown"></i>
</a>
<section class="hidden_ul">
<ul>
<li>Aerobics</li>
<li>Pilates</li>
<li>Yoga</li>
<li>Massage</li>
<li>Peeling</li>
<li>Bikini Area Sugaring</li>
<li>Piercing</li>
<li>Tattoo</li>
<li>Shaping</li>
<li>Sauna</li>
<li>Mud SPA</li>
<li>Needle Therapy</li>
<li>Shaping</li>
<li>Leech Therapy</li>
<li>Thai Massage</li>
<li>Wushu</li>
</ul>
</section>
</li>
<li>Clothing</li>
<li>Computers</li>
<li>Construction</li>
<li>Entertainment</li>
<li>Financial</li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
Food <i class="fa fa-chevron-right bu_chevright"></i>
<i class="fa fa-chevron-down bu_chevdown"></i>
</a>
<ul class="hidden_ul">
<li>Pizza</li>
<li>Cheboorackee</li>
<li>Khash</li>
<li>Pork</li>
<li>Hamburgers</li>
<li>Greek Salad</li>
<li>BBQ</li>
<li>Tortillas</li>
<li>Spaghetti</li>
<li>Pasta</li>
<li>Ice Cream</li>
<li>Jelly Sugar</li>
<li>Lolly Pop</li>
<li>Cupcakes</li>
</ul>
</li>
<li>Health</li>
<li>Kids</li>
<li>Services</li>
<li>Travel</li>
<li>Tourism</li>
</ul>
<div class="pzik">
<a href="javascript:void(0);" data-toggle=".sidebar_wrapper" id="sidebar-toggle_abs">
<img src="svg/filter.svg" class="filter_icon hvr-wobble-bottom">
</a>
<a href="javascript:void(0);" id="go-2-top" class="gotop_chevron">
<i class="fa fa-chevron-up"></i>
</a>
</div>
</div>
So, what I'm doing is selecting the above mentioned ul and put it within the empty section on a hover event and emptying it on a mouseleave, like this:
$(document).ready(function(){
var dropdownLi = $('li.dropdown');
var maskingSubLvl = $('.masking_sublevel');
var importedUl = $('.masking_sublevel ul');
var hiddenUl = $('.hidden_ul ul');
$(dropdownLi).on('mouseover',function(){
$(hiddenUl).appendTo(maskingSubLvl);
$(maskingSubLvl).css('display','block');
});
$(dropdownLi).on('mouseleave',function(){
$(maskingSubLvl).css('display','none');
$(importedUl).empty();
$(maskingSubLvl).on('mouseenter',function(){
$(this).css('display', 'block');
});
});
});
The problem is that with this piece of code I probably select just the first ul with the class of .hidden_ul', since as I hover on the other items (randomly), it keeps on loading the content of the first list. How can I select the VERY ul element with the same class that I'm currently hovering?
Thanks!

So you want to traverse from the element that has mouseover to the parent ul, which is a child of the grand-parent .hidden_ul
// remove this, it has no context to each drop down
// var hiddenUl = $('.hidden_ul ul');
$(dropdownLi).on('mouseover',function(){
$(this).closest('.hidden_ul').children('ul').appendTo(maskingSubLvl);
// though if there are no child uls in your lis, this will do
$(this).closest('ul').appendTo(maskingSubLvl);

Since your hidden_ul is direct child of .dropdown you need to get it using its parent context as below:
$(dropdownLi).on('mouseover',function(){
var hiddenUl=$(this).find('.hidden_ul')[0];//find the child
$(hiddenUl).appendTo(maskingSubLvl);
$(maskingSubLvl).css('display','block');
});
Update
Instead of appendTo try keeping changing the html of .maskingSubLvl so that no need to remove the content again before appending another. For Ex:
DEMO
$(document).ready(function(){
var dropdownLi = $('li.dropdown');
var maskingSubLvl = $('.masking_sublevel');
var importedUl = $('.masking_sublevel ul');
$(dropdownLi).on('mouseover',function(){
$(maskingSubLvl).css('display','block');
var hiddenUl = $(this).find('.hidden_ul ul').clone(); //clone the content
$(maskingSubLvl).html(hiddenUl);
});
$(dropdownLi).on('mouseleave',function(){
$(maskingSubLvl).css('display','none');
});
$(maskingSubLvl).on('mouseenter',function(){
$(this).css('display', 'block');
});
});

Hide my menu using jquery

I have the following bootstrap html menu:
<ul class="nav navbar-top-links navbar-right">
<li class="dropdown menustatus">
<a class="dropdown-toggle" href="#">
<div class="busy-status"></div>
<div class="online-status" style="display:none;"></div>
</a>
<ul class="dropdown-menu dropdown-user" style="margin-top: 10px;">
<li class="status">
<i class="fa fa-circle online"></i> Online
</li>
<li class="status">
<i class="fa fa-circle busy"></i> Busy
</li>
</ul>
</li>
</ul>
I'm trying to hide the menu when the user click on any item, like this:
$("#online-status").click(function (){
$(".busy-status").hide();
$(".online-status").show();
$("li.dropdown.menustatus.open").removeClass("open");
});
$("#busy-status").click(function (){
$(".online-status").hide();
$(".busy-status").show();
$("li.dropdown.menustatus.open").removeClass("open");
});
But it does not work.
I also tried:
$(".dropdown.menustatus.open").removeClass("open");
or
$("dropdown.menustatus").removeClass("open");
or
$(".menustatus").removeClass("open");
or
$(".open").removeClass("open");
But I couldn't hide the menu.
What I'm doing wrong.
Thanks for your help

#online-status is an anchor.
Try:
$("#online-status").click(function(e){
e.preventDefault();
....
});

Check how you did it with the other elements in the click events: You can in a similar way use .hide() and .show(), or even .toggle() if needed.
$(".menustatus").hide();
How specific the selector needs to be is up to you to decide / find out.
If you absolutely want to do it the "class way", my guess is that your ".open" class sets the visibility or display properties to visible/block or something similar to show the element, but your ".menustatus" does not seem to hide it. What I mean is: if you remove the .open class from the element, there is nothing that specifies whether it should be hidden or not. Try this:
.menustatus {
display: none;
}
.menustatus.open {
display: block; // Add !important if needed.
}
Change "block" to whatever you want, as long as it's not none.

How to add class dynamically using ajax.?

When i click on any name I have to add class "active" for selected name's anchor tag and as well as department names of that user.
<ul id="orglistingid">
<li>
<a>Sales </a> <!--Deparemtn Name -->
<ul id="dId">
<li>
<a>Rahul </a> <!--User -->
</li>
<li>
<a>Nitin </a>
</li>
</ul>
</li>
</ul>
<ul id="orglistingid">
<li>
<a class="active">Development</a>
<ul>
<li id="dId">
<a class="active">Rokesh </a>
</li>
<li>
<a>Preeti</a>
</li>
</ul>
</li>
</ul>
I am using below code, can anyone tell what correction i need to do..?
if (orgID != null && orgID == 'dId') {
$("#dId li a").removeClass("orglistactive");
$(this).attr("class","orglistactive");
var parentID = $(e.target).parent().parent().parent().attr("id");
alert($(e.target).parent().parent().parent().attr("id"));
$("#"+parentID+" a").attr("class","orglistactive");
}

Looks like you are trying to achieve something as shown below:
<script type="text/javascript">
var orgID = $('#dId');
if(orgID.attr('id') == 'dId'){
orgID.find('>li>a').addClass("orglistactive");
var parentID = orgID.attr("id");
alert(orgID.attr("id"));
}
</script>
But couple of things are found, are not correct from html and jquery perspective.
Id are unique but you have used 'dId' for more than one time.
e.target works only when there is an event attached with an element or can be captured using "window.event || e". In your code I could not see the purpose of e.target
Hope this helps! :)

This can be quickly achieved with a little of jQuery.
First Approach
$('ul a').click(function(){
$(this).addClass('orglistactive');
$(this).parent().parent().parent().find('a:first').addClass('orglistactive');
});
Take a look at a live demo: http://jsfiddle.net/augusto1982/6xM2P/
Second Approach
One thing to keep in mind is that this code works ok if there's no other list in the page. If this is not the case, you should use some CSS class to determine the object to bind the click function. Otherwise, the jQuery selector gets a bit messy.
$('#orglistingid li ul li a').click(function(){
$(this).addClass('orglistactive');
$(this).parent().parent().parent().find('a:first').addClass('orglistactive');
});
Example: http://jsfiddle.net/augusto1982/GXcvD/
Third Approach
I would also recommend you to add a class to each user anchor, to make it easier.
HTML
<ul id="orglistingid">
<li>
<a>Sales </a> <!--Deparemtn Name -->
<ul id="dId">
<li>
<a class='user'>Rahul </a> <!--User -->
</li>
<li>
<a class='user'>Nitin </a>
</li>
</ul>
</li>
</ul>
<ul id="orglistingid">
<li>
<a class="active">Development</a>
<ul>
<li id="dId">
<a class="active user">Rokesh </a>
</li>
<li>
<a class='user'>Preeti</a>
</li>
</ul>
</li>
</ul>
jQuery
$('.user').click(function(){
$(this).addClass('orglistactive');
$(this).parent().parent().parent().find('a:first').addClass('orglistactive');
});
Take a look at this second example: http://jsfiddle.net/augusto1982/GW4mt/
Final Approach
In order to avoid all the parent()...parent() calls, you could use the closest method, but you need to change your HTML a bit.
HTML
<ul id="orglistingid">
<li class='department'>
<a>Sales </a> <!--Deparemtn Name -->
<ul id="dId">
<li>
<a class='user'>Rahul </a> <!--User -->
</li>
<li>
<a class='user'>Nitin </a>
</li>
</ul>
</li>
</ul>
<ul id="orglistingid">
<li class='department'>
<a class="active">Development</a>
<ul>
<li id="dId">
<a class="active user">Rokesh </a>
</li>
<li>
<a class='user'>Preeti</a>
</li>
</ul>
</li>
</ul>
jQuery
$('.user').click(function(){
$(this).addClass('orglistactive');
$(this).closest('.department').find('a:first').addClass('orglistactive');
});
Demo: http://jsfiddle.net/augusto1982/e7PVF/
Like other comments, I'd recommend you to have unique IDs. While this is not a restriction, is a best practice.
