Jquery function add/remove class from div on button hover

I have this jquery script that I got some help with in creating in order to add/remove an "active" class to a div when hovering over a button.
Below a CodePen of what I have put together:
CodePen Link: https://codepen.io/dustin-keeslar/pen/dapLWM
It works well, however what I'm trying to change is to have whatever button was last hovered on, to keep the "active" class on the content. So that the content only changes when a different button is hovered over.
jQuery(document).ready(function() {
jQuery(".toggle-button").hover(function() {
var target = jQuery(this).data("target");
if (jQuery(this).hasClass("expand")) {
jQuery(this).toggleClass("expand");
jQuery("#" + target).removeClass("active");
} else {
jQuery(".toggle-button").removeClass("expand");
jQuery(".hidden-content").removeClass("active");
jQuery(this).toggleClass('expand');
jQuery("#" + target).toggleClass("active");
}
});
});
This will find a button that has data-target=content1" for example, and when it is hovered over it will toggle an "active" class to a div with the ID "content1". The problem is that when you are no longer hovering, everything disappears. I need the most recent hovered button to keep the "active" class on the content. But I also need the content to change dynamically when the next button is hovered over.

Then fix it to use mouseenter, and move your remove code to the top to remove your classes before adding them back to the element that's been entered. I don't understand exactly what you're trying to do here, but using mouseenter it should be something like:
jQuery(document).ready(function() {
jQuery(".toggle-button").mouseenter(function() {
jQuery(".toggle-button").removeClass("expand");
// jQuery(".hidden-content").removeClass("active");
$(".active").removeClass("active");
var target = jQuery(this).data("target");
jQuery("#" + target).addClass("active");
if (jQuery(this).hasClass("expand")) {
jQuery(this).removeClass("expand");
jQuery("#" + target).removeClass("active");
}
});
});

All you are missing is a check, to ensure the current item matches the target:
jQuery(this).attr('id') == target

jQuery program not working

I am having a problem using jQuery, merely due to inexperience using it. My program is meant to give the CSS class current to the links in my navbar if they are clicked, and remove the class from the previous owner of it.
Keep in mind I am very inexperienced in javascript, only picking it up in a few minutes for the sake of a school assignment.The script is simply not doing anything.
My Code:
$(document).ready(function() {
$('a').click( function(i){
var $current = $('a.current');
$(this).addClass('current');
$current.removeClass('current');
});
});
Edit 1: Strange bug, current class is applied to the whole document if I do not click a link, but instead click the document.

You should first remove the class, and then add it. Otherwise you will not have a class added if you click an anchor twice.
$(function() {
$('a').click(function() {
$('a.current').removeClass('current');
$(this).addClass('current');
});
});

Try this:
$current.removeClass('current');
$(this).addClass('current');
You need to first remove the active class, then add the current class for the current element.

You need to narrow down your code to only affect the links in the nav bar, as currently, you are targetting all <a> tags.
var navLink = $('.nav a');
navLink.on('click', function(e){
navLink.removeClass('current');
$(this).addClass('current');
});
In this code, the variable gets all instances of the nav links, and if one of them is clicked, will remove the current class from all of the links before adding it onto the one that was clicked.

Simple issue with jQuery Accordion

I have a simple jQuery accordion which works... almost perfectly :)
As you can see from the demo, I currently have the navigation "open" as I'm in the "Team" page.
Is it possible when I click 'About Us', it closes the element altogether. As you can see from the demo it closes it, but then quickly re-opens it. I guess this occurs because of the code on line 27 of my CSS.
Here is my demo: http://jsfiddle.net/URYzK/5/
Here is my JavaScript:
jQuery(function($) {
$('#accordion > li > a').click(function (e) {
if ($(this).next('ul').length == 0) {
// link is for navigation, do not set up accordion here
return;
}
// link is for accordion pane
//remove all the "Over" class, so that the arrow reset to default
$('#accordion > li > a').not(this).each(function () {
if ($(this).attr('rel')!='') {
$(this).removeClass($(this).attr('rel') + 'Over');
}
$(this).siblings('ul').slideUp("slow");
});
//showhide the selected submenu
$(this).siblings('ul').slideToggle("slow");
//addremove Over class, so that the arrow pointing downup
$(this).toggleClass($(this).attr('rel') + 'Over');
e.preventDefault();
});
});
Many thanks for any help here.

Remove display:none from #accordian ul and remove the .children CSS entirely. I believe this creates the behavior you want. You were setting the children ul to be display:none, and then trying to force .children, which is a ul, to be display:block later, which is why they were fighting.
Updated your jsFiddle as well.

.each() on JQuery Dropdown

I'm trying to create a JQuery Dropdown similar to the one used in bootstrap.
The problem which arises is that when an individual list item is clicked, all sub navigation's display block.
Now I know this issue can be resolved with .each() but my code does not seem to work.
Please find the example here; http://jsfiddle.net/N7xgC/
Apologies if this question has already been asked before.

Try this modification:
http://jsfiddle.net/N7xgC/1/
$(function() {
$('.main > li > a').each(function() {
$(this).click(function() {
// When the anchor is clicked, find the next .sub element and toggle it
$(this).next('.sub').toggle();
});
});
});
I changed yours to toggle the element with the class .sub 'next' to the clicked anchor.

You cannot select all .sub and toggle them. You need to get only the one next to the a-element that is clicked.
Try this instead:
$(this).next(".sub").toggle();
Updated your fiddle so you can see it in action: http://jsfiddle.net/N7xgC/3/

$('.main li a').on('click', function() {
$(this).next('.sub').toggle();
});

Using $(this) with jQuery not always working

On line 6 below, I have $("ul.tabrow li").removeClass("active"); //Remove any "active" class If I change it to use $(this).removeClass("active") instead then it does not work as I thought it was.
The code works how I want it to right now, I am just wanting to know why what I mentioned above does not work, on line 7 below I use $(this) on what appears to be the same selector and that works on line 7's code but differently on line 6.
Can anyone explain this?
$("ul.tabrow li").bind({
click: function() {
return false;
},
mouseenter: function() {
$("ul.tabrow li").removeClass("active"); //Remove any "active" class
$(this).addClass("active"); //Add "active" class to selected tab
$(".tab-box").hide(); //Hide all tab content
var activeTab = $(this).find("a").attr("href"); //Find the rel attribute value to identify the active tab + content
//$(activeTab).fadeIn(); //Fade in the active content
$(activeTab).show(); //Fade in the active content
return false;
}
});

You actually want to use $("ul.tabrow li") on line 6. This is because $(this) only refers to the current list item, not all of them.
$(this) is not a replacement for the selector, it refers to the current active element (the one you are mousing over). So using this on line six removes the active class from the current element and then immediately adds it back. The result is essentially nothing happening.
If you don't want to repeat the selector then you may want to use something more generic like
$(this).siblings().removeClass('active');
