We Keep Coding

Im trying to create a pop-up box type when hovering over specific text, but the text only hides and does not show further

Im trying to create a pop-up box that will pop-up when you hover over text. The text disappears but it does not reappear when you hover your mouse over it. Any improvements that can be made to the code below?
$(document).ready(function(){
$("clo-t").hide();
$("clo").hover(function(){
$("clo-t").show();,
$("clo-t").hide();
});
})

You should use mouseout and mouseover instead
$(document).ready(function() {
$(".clo").mouseover(() => {
$(".clo-t").show();
}).mouseout(t => {
if (!$(t.target).hasClass("clo-t"))
$(".clo-t").hide();
})
})

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

Switch between two pages with toggleClass

I've got a page with 2 buttons and 2 divs which are hidden.
When you click the first button the first div should appear, and if you click the second button the second div should appear.
I've managed to get that to work, but what I can't get to work is, that if I have the first div open, and click the second button, I would like it to show the second div and close the first div.
$(document).ready(function() {
$('button.hh').click(function() {
$(".hh_facebook").toggleClass("vis");
$(".hg_facebook").toggleClass("skjul");
});
});
$(document).ready(function() {
$('button.hg').click(function() {
$(".hg_facebook").toggleClass("vis");
$(".hh_facebook").toggleClass("skjul");
});
});
Here is my fiddle:

Best regards

your js code is a bit incorrect.
You call twice $(document).ready(function() { ... Is enough once time.
try this:
$(function(){
$("button.hh").on("click", function(){
$(".hh_facebook").show();
$(".hg_facebook").hide();
});
$("button.hg").on("click", function(){
$(".hh_facebook").hide();
$(".hg_facebook").show();
});
});
see the updated fiddle: http://jsfiddle.net/4mWLk/5/
update if you want to hide div after clicking on same button: http://jsfiddle.net/4mWLk/8/
Use toggle instead of show (for your comment at my answer)
PS: I updated CSS because there was not neccessary.

If you want it with classes so you can have more control over the effect in case you decide to change it later, you should do it like this:
http://jsfiddle.net/4mWLk/7/
$(document).ready(function() {
$('button.hh').click(function() {
$(".hh_facebook").toggleClass("skjul vis");
$(".hg_facebook").removeClass("vis").addClass("skjul");
});
$('button.hg').click(function() {
$(".hg_facebook").toggleClass("skjul vis");
$(".hh_facebook").removeClass("vis").addClass("skjul");
});
});
Html:
<div class="hh_facebook skjul">test1</div>
<div class="hg_facebook skjul">test2</div>
What it does is like this:
first the divs start with skjul class so they are in hidden state.
when a button is pressed, toggle both the skjul and vis classes (one is removed, the other is added)
make sure the second div is hidden.

Drop down only one menu at a time

So far I have this drop-down menu. When I click on either "Menu", "Menu1" or "Menu2", the links under it will drop down.
The problem:
I need to display only one drop-down at a time, so that the user can switch between them.
I tried to apply css('overflow', 'hidden'); to the menu currently dropped down, but it won't work, since the overflow: visible !important; is applied to the .clicked class.
Please help, anything will be highly appreciated!

Try when you click on a element remove class clicked from all elements and add class clicked to the element that is clicked
$("#product-menu>ul>li").click(function () {
var hidden = $(this).find('.clicked');
$("#product-menu>ul>li").removeClass('clicked');
$(this).addClass('clicked');
$('.productSubmenu').width(menuWidth);
});
DEMO
UPDATE
If you want also on second click menu to be closed try checking if clicked item has already class clicked:
$("#product-menu>ul>li").click(function () {
var hidden = $(this).find('.clicked');
if ($(this).hasClass('clicked')) {
$(this).removeClass('clicked')
} else {
$("#product-menu>ul>li").removeClass('clicked');
$(this).addClass('clicked');
}
$('.productSubmenu').width(menuWidth);
});
DEMO2

You also might want to close the links
$("#product-menu>ul>li").click(function () {
var hidden = $(this).find('.clicked');
$("#product-menu>ul>li").removeClass('clicked');
$("#product-menu .productSubmenu2").hide(); // this one I added
$(this).addClass('clicked');
$('.productSubmenu').width(menuWidth);
});

Mouse hover and click to display text with CSS and JS

Currently I have this: http://jsfiddle.net/TW2Le/95/
I want to be able to click the box to display the text, then click anywhere else to hide the text. One click = show, 2nd click anywhere else = hide. (This part works)
When it is not "clicked", it should show the text when I hover over, but it should not display the text on top of the old text when I hover it while it is clicked.
i am running into a problem, where it displays double the text when I hover over while it is clicked. I have no idea how to disable "hover" while it is under the show condition. It should not repeat the same texts.

http://jsfiddle.net/TW2Le/97/
Try this.
$('.wrap').removeClass('reveal');
$('.wrap').addClass('reveal');
I added these into your jquery so that when "show" is visible, hovering does nothing.

DEMO
JS
$(function() {
$(document).on('click', function(e) {
if ( $(e.target).closest('.wrap').length ) {
$('.show').slideToggle();
$('.noshow').slideToggle();
$(".here").addClass("hide");
}else{
$('.show').slideDown();
$('.noshow').slideUp();
$(".here").removeClass("hide");
}
});
});
Add new CSS rule
.wrap:hover .here.hide {
display:none;
}
