jQuery firing parent functions before children (slideUp and slideDown)

In short, I have a 2 main links (Private Car and Commercial Vehicle) each with a specific class attached to their anchor tags. The same class names are used on the li tags of a second sublink ul to match them with to two top links. The idea is that each time a main link is clicked, the following happens:
The sublink ul slides up
All the li's inside are hidden
The li's with the corresponding main link class are shown
The sublink ul slides down showing only the correct li's
Unfortunately that is not the order that the functions fire in. What happens is this:
The sublink ul slides up
The sublink ul slides down
All list elements inside are hidden
The relevant list elements slide down
Any idea on how I can get the order to fire as I want it?
Here is the code
$('.insurer ul.toplinks a').click(function(e) {
e.preventDefault();
var sublinkCategory = $(this).attr('class'),
subLinksToShow = $(this).parent().parent().parent().find('li.' + sublinkCategory),
subLinksList = $(this).parent().parent().parent().find('ul.sublinks'),
allLinks = $(subLinksList).find('li');
// First time
if ($(subLinksList).is(":hidden")) {
$(subLinksToShow).slideDown();
$(subLinksList).slideDown();
// List visible but new links invisible
} else if ($(subLinksList).is(":visible") && $(subLinksToShow).is(":hidden")) {
$(subLinksList).slideUp(function() {
$(allLinks).hide(function() {
$(subLinksList).slideDown(function() {
$(subLinksToShow).slideDown();
});
});
});
}
});

Your code isn't working while we don't have the fully code.
This works, note the comments in the code to see what happens on the line under the comment.
$(function() {
// hide by default

// get the classname
var cl = $(this).attr('class');
// slide up
$('.sublinks').slideUp("slow", function() {
//on callback (= after slide up is done)
// show all links
$('.sublinks li').show();
// hide the ones not having the right class
$('.sublinks li:not(.'+cl+')').hide();
// slide down again
$('.sublinks').slideDown("slow");
});

How to change active class on li element in JQuery and redirect the user to the specified page when li elelment is clicked?

I have the the following in my script tag. However, whenever I click the on test.php or test2.php li links, I am not redirected to the respective pages.
However, the active class changes from the index.php file to the test.php or test2.php file depending on which link has been clicked but I am not directed to the page. I attempted to the solutions in the following links, but now of them produce the desired result that I want, which is to redirect me to the page clicked and update the active class to the li element.
How to change active class while click to another link in bootstrap use jquery?
Active link after click
Whenever I uncomment this line e.preventDefault(), I am able to navigate to the link that have been click but the active class is not updated to the the
li elememnt clicked, but when the said line is commented, I am not able to navigate to the page clicked, instead, the active class is updated on the li element clicked.
<div class="menu">
<ul class="list">
<li class="header">MAIN NAVIGATION</li>
<li class="active">
<a href="index.php">
<i class="material-icons">home</i>
<span>Home</span>
</a>
</li>
<li class="">
<a href="test.php">
<i class="material-icons">group</i>
<span>Test</span>
</a>
</li>
<li class="">
<a href="test2.php">
<i class="material-icons">people</i>
<span>Test2</span>
</a>
</li>
</ul>
</div>
And the script code:
$(document).ready(function () {
$('.menu .list a').click(function(e) {
$('.menu li.active').removeClass('active');
var $parent = $(this).parent();
$parent.addClass('active');
e.preventDefault();
});
});
The contents of test.php are as follows:
<body class="theme-red">
<nav class="navbar">
<?php include_once('navbar.html'); ?>
</nav>
<section>
<aside id="leftsidebar" class="sidebar">
<?php include_once('left-side-bar.html');?>
</aside>
</section>
<section class="content">
<div class="container-fluid">
<div class="row clearfix">
<table id="tbl-users" class="table">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
</thead>
<tfoot>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
</tfoot>
<tbody>
<?php
$accounts = get_details();
foreach($accounts as $acc){
?>
<tr>
<td><?php echo $acc['id']; ?></td>
<td><?php echo $acc['name']; ?></td>
</tr>
<?php
}
?>
</tbody>
</table>
</div>
</div>
</section>
</body>

Why is the problem arising?
The problem arises that, when you use e.preventDefault() on click of
anchor tag, the default behaviour is to redirect the page and that's
why the page doesn't load but the active class gets added. But when
you don't use e.preventDefault(), the page redirects immediately
and the change you did happen but before it was redirected and not
for the new page(which could be redirected current page or some other page), that's why you can't see the class active added to
it.
.
How to fix the problem?
Well, there are a couple of ways to go about it. I'd say that from the
test.php or test2.php return a value, which you can validate against
the javascript with if-else conditions, if the value matches you make
that li class as active.
Here's the changes you need to make:
Add a span on each of your pages to which you have hyperlinked i.e test.php, test2.php, etc. having text the same as your hyperlink in the anchor tag so for test.php add a span as:
<span id="curpage" style="display:none;">test.php</span>
Then, add a script at the end of your body tag (you may be able to add this script in a seperate file and include in all of your php files using <?php include(".."); ?> :
$('a[href=\"' + $("#curpage").text() + '\"]').parent().addClass("active");
Here's a sample code, that you can try and implement. Make 2 files in
the same directory named as a.html having the code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<span id="curpage" style="display:none;">a.html</span>
<div class="menu">
<li>1</li>
<li>2</li>
</div>
<script>
$('a[href=\"' + $("#curpage").text() + '\"]').parent().css("color","red");
</script>
</body>
</html>
And b.html having the code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<span id="curpage" style="display:none;">b.html</span>
<div class="menu">
<li>1</li>
<li>2</li>
</div>
<script>
$('a[href=\"' + $("#curpage").text() + '\"]').parent().css("color","red");
</script>
</body>
</html>
And now when you change the pages by clicking the link, you can see
how the color of bullet changes.

I don't think you should be changing the "active" class just when the li links are clicked. Think that when you redirect your users to a specific page from another, the li links "OnClick" event won't be fired at all, hence, the active menu link won't be displayed appropriately.
Now, what I usually do to solve this issue (don't know if it's the most elegant solution, but it works) is to place a tag at the top of each html content template (I'm assuming you're using templates for the Header, Footer and Content here), I give it a descriptive ID, like "page-name" or "section", and add a data attribute to it with the name of the menu link that this page "belongs" to:
<div id="page-name" data-page="home-page">
Then with JQuery you can ask for the div's data like this:
var current_page = $("#page-name").data("page");
And simply alter the menu links class depending on what page the user is currently in:
// remove the "active" class from ALL the links first
$(".menu li a").removeClass("active");
if (current_page === "home-page") {
// add the "active" class just to the link you want
$("#home-page-link").addClass("active")
}
Of course, you would do that with a switch and you would have to load the js file on ALL pages (that's why the use of the Header template is so important, since you would just need to include it once). Also, in the html "data-page" attribute, the "page" part can be anything, just remember to call it appropriately later.
Hope I helped.

To dynamically add a class, on page load, to the navigation item of the current page, consider:
Checking the current page url: $(location).attr('href') OR
$(location).attr('pathname')
Looping through anchor elements (a) of the navigation menu to
determine if any of the href attribute values match the current
page url with a conditional check using the .indexOf() method:
if(anchorEl.indexOf(currentPageUrl) >= 0)
If any do, add the required class, using the .addClass() method:
$(this).addClass('current');
Code Snippet Demonstration:
Note: Intended for the sake of demonstration
The code snippet embedded below uses specific urls to provide a working example and to demonstrate the intended functionality. Adjust accordingly to apply to a given production environment.
$(document).ready(function () {
var currentPageUrl = $(location).attr('href'), // store current page url in variable
anchorEl;
$('.menu a').each(function(){
anchorEl = $(this).attr('href'); // store href atribute of current anchor element in iteration
console.log('anchor link url:',anchorEl);
console.log('current url of window:',currentPageUrl);
if(anchorEl.indexOf(currentPageUrl) >= 0) { // if anchor element contains
$(this).addClass('current');
console.log('class "current" was added.');
}
});
});
/*
Note:
$(location).attr('href') = full absolute path (https://stacksnippets.net/js)
$(location).attr('pathname') = relative path (/js)
*/
.current {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="menu">
<ul class="list">
<li>
<a href="https://stacksnippets.net/foobar1">
<span>foobar #1</span>
</a>
</li>
<li>
<a href="https://stacksnippets.net/foobar2">
<span>foobar #2</span>
</a>
</li>
<li>
<a href="https://stacksnippets.net/js">
<span>This should be the <em>current</em> url</span>
</a>
</li>
</ul>
</div>

You should know e.preventDefault() will prevent default behavior of that object which called on it (redirect in this case). So you are preventing your application from redirect to that href you specified.
You can change your function code like this:
$(document).ready(function () {
$('.menu .list a').click(function(e) {
$('.menu li.active').removeClass('active');
var $parent = $(this).parent();
$parent.addClass('active');
e.preventDefault();
//Here is needed change
location.href = $(this).attr('href');
});
});
Edit 1:
So you can work like this approach:
1) Specify a class name for each li tag
2) Send the class name that must has active class after redirection and page load
3) Read the passed class name from url and add/remove to/from your li tags
So your html code will be as following:
<div class="menu">
<ul class="list">
<li class="header">MAIN NAVIGATION</li>
<li class="home active">
<a href="index.php">
<i class="material-icons">home</i>
<span>Home</span>
</a>
</li>
<li class="group">
<a href="test.php">
<i class="material-icons">group</i>
<span>Test</span>
</a>
</li>
<li class="people">
<a href="test2.php">
<i class="material-icons">people</i>
<span>Test2</span>
</a>
</li>
</ul>
</div>
If you need to script code according to this solution which I explained, so I will update my answer.
Edit 2:
You need to have below script codes in your file:
function setActiveClass() {
//Remove active class from all li tags
$('.menu li.active').removeClass('active');
//Find current url
var url = $(location).attr('href');
if (url.contains("activeClass")) {
//Find the index of active class in url
var start = url.indexOf("#activeClass");
//Add 6 unit to start index because of the longest class name is people which has 6 character
var end = start + 6;
//Fetch passed class name from url
var className = url.substring(start, end);
//Add active class corresponding to passed class name
if(className.contains("home"))
$(".home").addClass('active');
else if(className.contains("group"))
$(".group").addClass('active');
else
$(".people").addClass('active');
} else {
//Add active class for default mode (when we have not any redirect yet)
$("#defaultLiTag").addClass('active');
}
}
$(document).ready(function () {
//Call the function
setActiveClass();
$('.menu .list a').click(function(e) {
e.preventDefault();
var classNameOfParent = $(this).parent().attr('class');
var classNameToBePassedByUrl = "home";
if(classNameOfParent.contains("group"))
classNameToBePassedByUrl = "group";
else if(classNameOfParent.contains("people"))
classNameToBePassedByUrl = "people";
location.href = $(this).attr('href') + "#activeClass=" + classNameToBePassedByUrl;
});
});

i had the same problem after a lot of searching i could find this solution in this link i hope it could help you. Although you should remove class active and add class active to clicked navbar item ,you should use location.href to add active class when the new page reload.

JQuery each function toggle class

So i have some code like this
<ul>
<li>Example</li>
<li>Example</li>
<li>Example
>
<div class="Menu" style="display:none;">
Some thing
</div>
</li>
<li>Example
>
<div class="Menu" style="display:none;">
Some thing
</div>
</li>
<li>Example</li>
</ul>
Then i use a JS code like this
$("ul li .SplitCtrl").each(function(index) {
$(this).on("click", function(){
$(".Menu").fadeIn(800).slideDown(800);
});
});
But when i using this, all the ".Menu" element will be fade in :(
Please correct my code...

You need to target the specific .Menu that is the one next to this. ELse it will target all element with .Menu class. You can use jquery next
$("ul li .SplitCtrl").each(function(index) {
$(this).on("click", function(){ //changed here
$(this).next(".Menu").fadeIn(800).slideDown(800);
});
});
Check out this JSFIDDLE

jQuery doesn't know which element to open because there are no id's assigned to the menu items. So it opens everything in the .SplitCtrl class because it doesn't know any better. If you assign some id's to the elements, then it will know what to open and when. Using your code so as to minimize modifications, the following will work for you. Note the addition of id's to both of the .SplitCtrl items and the .Menu items, and using the click function and passing in the id of the item that the click originated from. If you embed further elements, this will still work in the case that it isn't the next element following your class, or if you want it to trigger other items on the page in addition to the menu items.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
</head>
<body>
<ul>
<li>Example</li>
<li>Example</li>
<li>Example
>
<div class="Menu" id="menu1" style="display:none;">
Some thing
</div>
</li>
<li>Example
>
<div class="Menu" id="menu2" style="display:none;">
Some thing
</div>
</li>
<li>Example</li>
</ul>
<div id="surprise1" style="display:none;">Now I'm open too!</div>
</body>
</html>
<script>
$(document).ready(function() {
$("ul li .SplitCtrl").click(function(event){
var item = '#menu' + event.target.id;
var surprise = '#surprise' + event.target.id;
$(item).fadeIn(800).slideDown(800); // open the menu item
$(surprise).fadeIn(800).slideDown(800); // open another element
});
});
</script>
In order to toggle the items, you can add something that first hides everything that's open and then makes the newly selected item visible:
//...same code as above to this point
<div id="surprise1" class="Surprise" style="display:none;">Now I'm open too!</div>
</body>
</html>
<script>
$(document).ready(function() {
$("ul li .SplitCtrl").click(function(event){
var item = '#menu' + event.target.id;
var surprise = '#surprise' + event.target.id;
$(".Menu").fadeOut(100); // Hide all items of class .Menu
$(".Surprise").fadeOut(100); // Hide other items of class .Surprise
$(item).fadeIn(800).slideDown(800); // open the menu item
$(surprise).fadeIn(800).slideDown(800); // open another element
});
});
</script>
So now, all the .Menu items in that class are toggled off before the new one is displayed (even though only one displays at a time). Note the added class for "Surprise" to be able to hide all the external elements as well. There are lots of ways to toggle items so this is just one way you could accomplish it.

Removing and adding Classes on Dropdown Menus on Hover

I have a Navigation built that have drop down menus,
HTML STRUCTURE LIKE SO
<li class="c-header__subnav-item c-header__subnav-item-is-hidden c-header__subnav-item-is-visible-md">
<a class="c-header__subnav-links u-caps js-c-header__subnav-trigger" href="#">
Action Review Review
<i class="fa fa-angle-down fa-lg c-btn__icon-right-sm"></i>
</a>
<ul class="c-header__subnav-dd">
<li class="c-header__subnav-dd-item">
<a class="c-header__subnav-links c-header__subnav-links--dd" href="#">

</a>
</li>
<li class="c-header__subnav-dd-item">
<a class="c-header__subnav-links c-header__subnav-links--dd" href="#">

</a>
</li>
<li class="c-header__subnav-dd-item">
<a class="c-header__subnav-links c-header__subnav-links--dd" href="#">

</a>
</li>
<li class="c-header__subnav-dd-item">
<a class="c-header__subnav-links c-header__subnav-links--dd" href="#">
Recent Recordings
</a>
</li>
</ul>
</li>
When You Hover On the a.js-c-header__subnav-trigger
It addes a class to its self as well as its sibling ul ( the dropdown menu)
This is perfect but since the hover is triggered on the 'a' element If I toggle the class when and I go to hover on the drop down menu it gets removed before I can because of hovering off the 'a' element.
If I just add the classes and do not use toggle how would I remove both classes once I hover off the A element or Dropdown menu.
What needs to be achieved is
1.) If main nav link is hovered add an active class to itself and drop down is triggered and can be seen. If you hover out WITHOUT engaging the dropdown both active and dropdown class are removed
2.) If main nav link is hovered add an active class to itself and if dropdown IS engaged by user keep both classes until dropdown is hovered out of or 'A' Element.
CURRENT JQUERY CODE
;(function($, window, document, undefined) {
var $win = $(window);
var $doc = $(document);
var $classes = {
SubNavTrigger : 'js-c-header__subnav-trigger',
SubNavItemActive : 'c-header__subnav-item-is-active',
SubNavDropDown : 'c-header__subnav-dd',
SubNavDropDownActive : 'c-header__subnav-dd-is-active'
};
var _isMobile = false;
_isMobile = ($win.width() <= 1024) ? true : false;
// Check if user is on touch on page load
// if isMobile use click events
// if not mobile use hover events
if(_isMobile) {
$("." + $classes.SubNavTrigger).on('click', function(){
if ( $(this).hasClass( $classes.SubNavItemActive ) ){
// If Item has active class removeClass
$(this).removeClass( $classes.SubNavItemActive )
} else {
// If Item does not have active class addClass
$(this).addClass($classes.SubNavItemActive);
} //End if
// Add Active Class To Subnav.
$(this).siblings().toggleClass($classes.SubNavDropDownActive);
});
} else {
$("." + $classes.SubNavTrigger).on('hover', function(){
$(this).addClass($classes.SubNavItemActive);
// Add Active Class To Subnav.
// If set to toggle impossible to hover on this menu.
$(this).siblings().addClass($classes.SubNavDropDownActive);
});
}
})(jQuery, window, document);
Thanks In Advance for any help.

So I would make a few changes, I would move the s-c-header__subnav-triggerclass to the parent li. I would then change the jquery to use the hover(in,out). The in function would look something like
function () {
$(this).addClass($classes.SubNavItemActive);
// Add Active Class To Subnav.
$(this).children().addClass($classes.SubNavDropDownActive);
}
and the out
function () {
$(this).removeClass($classes.SubNavItemActive);
// Add Active Class To Subnav.
$(this).children().removeClass($classes.SubNavDropDownActive);
}
Here is a jsfiddle

jQuery adding active class to nav, now nav not working

So, I'd like my breadcrumb nav to show the user which page he/she is on by having the be a different color according to the page they are on. I.e. if on home, the home link is gray whilst the others remain black.
To do this I've added the following code to my app:
$(function(){
$('.breadcrumb li a').on('click', function(e){
e.preventDefault(); // prevent link click if necessary?
var $thisA = $(this);
var $li = $thisA.parent('a');
if (!$thisA.hasClass('active'))
{
$li.find('a.active').removeClass('active');
$thisA.addClass('active');
}
})
})
However, with the above code it never releases the active class when I also click events for example they end up both just being gray. Also, the page doesn't switch it stays on home page but with home and events grayed out.
The css:
.breadcrumb li a.active { color: #999999;}
The html
<ul class="breadcrumb">
<li>
<a class="active" href="/profiles"> Home</a>
</li>
<li>
<a class="active" href="/events"> Events</a>
</li>
<li>
Messages
</li>
<li>
My Profile
</li>
</ul>

Change
var $li = $thisA.parent('a');
to
var $li = $thisA.parents('ul');
because this line
$li.find('a.active').removeClass('active');
looks for a child a.active and your original $li would be null because your original line is trying to find a a that is a parent of the clicked a.
