JQuery Toggle Slide – display element when other elements toggle closed

JSFiddle: http://jsfiddle.net/ncuacvcu/
DIV home is displayed by default.
When I click on LINK one/LINK two, DIV one/DIV two replaces DIV home. When I click on LINK one/LINK two again, DIV one/DIV two toggles shut, leaving an empty white space. How do I get DIV home to display again at that moment?
At the same time, if DIV one is open and I click on LINK two, I want DIV one to be replaced by DIV two (i.e. without going through DIV home).
Here's what I tried (and some variations), but I can't get it to work:
$("a#one_toggle").click(function()
{
$(".hideall").not(".one").slideUp();
$(".one")slideToggle(function(){
if($('#client1').is(':visible')){
$('#client0').SlideUp();
} else{
$('#client0').SlideDown();
}
});
});
Thanks in advance for any tips!

You need to use the callback of slideToggle and check if the div with class home is visible or not then you show it.
http://api.jquery.com/slidetoggle/
http://api.jquery.com/is/
$(function() {
$("a#one_toggle").click(function() {
$(".hideall").not(".one").slideUp();
$(".one").slideToggle('slow', function() {
showHome($('.one'));
});
});
$("a#two_toggle").click(function() {
$(".hideall").not(".two").slideUp();
$(".two").slideToggle('slow', function() {
showHome($('.two'));
});
});
});
function showHome(elementToCheck) {
// now we know if the div to check is visible or not
if (!$(elementToCheck).is(':visible')) {
// the div is not visible so we show it
$('.home').slideDown();
}
}
.one,
.two {
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
link one
link two
<div class="home hideall">

</div>
<div class="one hideall">

</div>
<div class="two hideall">

How to use jQuery .hover() in combination with Overflow

Well, i am stucked and can't find the answer myself. Hopefully someone can give me a hint.
I try to fullfill the following requirements:
There should be a Newsblock within a HTML Page with a fixed width and
height.
In this Newsblock only the title of the news are visible.
Those news are "collapsed" by default and should "expand" if the Mouse is over it.
Due the fact that the 'Newsblock' is limited by its height, there should be a Scrollbar visible. But only if the currently expanded news makes it necessary, so the user can Scroll down.
Newstitle and Newstext should never leave the Newsblock.
so far so good, i was able to fullfill all those demands except the one with the Scrollbar. If i try to reach the Scrollbar out of the currently expanded news it collapses again and the Scrollbar disappears. I understand that my .hover is configured that it always SlideUp if i leave the newsentry and the Scrollbar isn't a part of the newsentry div. But i have no idea what to change to still have an overall Scrollbar for the Newsblock, but won't disappear if i try to 'reach' it.
P.s.: A Scrollbar only per Newsentry looks weird. Thats why i want 'bind' the scrollbar to the parent container :S
HTML
<div id="newsblock">
<div> // some auto generated div's i have to life with, so the news entries are not 'direct' children of the newsblock.
<div class="newsentry">
<div class="newstitle">...</div>
<div class="newstext">...</div>
</div>
... another 9 'newsentry' divs.
</div>
</div>
JS
$(".newsentry").hover(
function() {
$(this).children(".newstext").stop(true,true).slideDown();
},
function() {
$(this).children(".newstext").stop(true,true).slideUp();
}
);
CSS
.newsblock {
height: 200px;
overflow-y: auto;
}

Instead of closing a .newsentry when the cursor goes out of it, a solution can be to close it only when it enters another .newsentry or when it leaves #newsblock.
The scrollbar being part of #newsblock, the entry isn't closed anymore when you go on it.
EDIT: Following our discussion about the scroll issue, I added a step callback to the closing animation to make sure that the top of the .newsentry getting opened remains visible when the other entries are getting closed.
Here is a working example:
var $newsblock = $("#newsblock");
function closeAllNews(slideUpArgs){
return $(".newstext").stop(true).slideUp(slideUpArgs);
}
function openNews(news, slideDownArgs){
$(news).find(".newstext").stop(true).slideDown(slideDownArgs);
}
function ensureNewsTopVisible(news){
// Check if the top of the newsentry is visible...
var top = $(news).position().top;
if(top < 0){
// ...and if not, scroll newsblock accordingly.
$newsblock.scrollTop($newsblock.scrollTop() + top);
}
}
$(".newsentry").each(function(){
var $this = $(this);
// When the mouse enter a news entry...
$this.on("mouseenter", function(){
// ...close all opened entries (normally there is at most one)...
closeAllNews({
// (while making sure that the top of this entry remains visible
// at each step)
step: ensureNewsTopVisible.bind(null, $this)
});
// ...open this newsentry.
openNews($this);
});
});
// When the mouse get out of the newsblock, close all news.
$newsblock.on("mouseleave", closeAllNews);
.newstitle {
font-size: 2em;
}
.newstext {
display: none;
}
#newsblock {
max-height: 150px;
overflow: scroll;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="newsblock">
<div>
<div class="newsentry">
<div class="newstitle">News 1</div>
<div class="newstext"></div>
</div>
<div class="newsentry">
<div class="newstitle">News 2</div>
<div class="newstext"></div>
</div>
<div class="newsentry">
<div class="newstitle">News 3</div>
<div class="newstext"></div>
</div>
<!-- Etc. -->
</div>
</div>
<!-- Ignore the script below. It is just filling in the news' text. -->
<script>
$(".newstext").each(function(i, newstext){
$.get("http://baconipsum.com/api/?type=meat-and-filler&format=html&paras=5&num=" + i)
.then(function(ipsumHtml){
$(newstext).html(ipsumHtml);
});
});
</script>

Try this:
$(".newsentry, .newsblock").hover( // <-- changed
function() {
$(this).children(".newstext").stop(true,true).slideDown();
},
function() {
$(this).children(".newstext").stop(true,true).slideUp();
}
);
This makes sure the block stays open when you hover either over the header or the block itself.
Is that what you mean?

There would be a joke , if i am wrong .. what i thing just change your css as
/* not .newsblock **/
#newsblock {
height: 200px;
overflow-y: scroll;/* not auto*/
}

It will be a lot better if you use click operation instead of hover to slide down news text block because the user can accidentally hover over any of the news entry in order to reach for the scroll bar. I think you need a accordion like functionality. You can use the below code if you are fine with click instead of hover.
$(".newsentry").click(
function() {
$(".newstext").stop(true,true).slideUp();
$(this).children(".newstext").stop(true,true).slideDown();
}
);
Or use the below one to go with hover.
$(".newsentry").hover(
function() {
$(".newstext").stop(true,true).slideUp();
$(this).children(".newstext").stop(true,true).slideDown();
},
function(){}
);
This will not close the news text block until you accidentally hover over another news entry.

Jquery Hover - allow hover on another DIV the appears on hover of a button

I have a homepage with 4 buttons. When hovered over a button, a menu appears behind the buttons. When you hover over another button, a different colored menu appears in it's place.
Currently, I can get the buttons to show the menus, but when I hover onto the menus (and hover off the button) I lose the menu.
Here's my simple code:
Jquery at top:
$(".mybutton").hover(
function () {
$(".mybox").fadeIn();
},
function () {
$(".mybox").fadeOut();
}
);
$(".mybutton2").hover(
function () {
$(".mybox2").fadeIn();
},
function () {
$(".mybox2").fadeOut();
}
);
And my HTML:
<div class="mybox">
<div style="position: absolute;">
Item 1
Item 2
</div>
</div>
<div class="buttons">
<div class="mybutton">
/* Button image here */
</div>
<div class="mybutton2">
/* Button 2 image here */
</div>
</div>
So I need some way to keep the box that fades in active when it is hovered over. I was thinking of not doing the callback for the fadeout, and somehow only doing the fadeout if they fade off the .mybox DIV or if they hover over another button. But it's a little unclear to me how to accomplish that.
Thanks in advance.

you need to include your menu and the button inside a container and have a hover event on the container. this way your menu will be visible as long as you're hovering over the container.
here's what you need to do.
declare the container like this with your menu and button both inside it.
<div id='container'>
<div class="mybox box">
<div style="position: absolute;">
Item 1
Item 2
</div>
</div>
<div class="buttons">
<div class="mybutton">
/* Button image here */
</div>
</div>
</div>
here's what you need to do in jquery.
$(document).ready(function() {
$("#container").hover(
function() {
console.log($(".mybox").fadeIn());
$(".mybox").fadeIn();
},
function() {
$(".mybox").fadeOut();
}
);
});
here's a working JSFIDDLE with 2 buttons

It's because you're no longer hovering over the button and instead going to a different element "mybox" so you could rearrange the html structure for it to work by keeping the menu in the button class like so:
<div class="buttons">
<div class="mybutton">
/* Button image here */
<div class="mybox">
<div style="position: absolute;">
Item 1
Item 2
</div>
</div>
</div>
</div>
this should keep the menu active as long as the curser is in there.

I don't recommend this as a UI design pattern for various reasons (one of them being the complexity of implementing it); you could instead consider changing it so that the menu appears when the user clicks.
Having said that, here's a way to do it. Get rid of your existing fadeOut() calls and add this:
$("body").on("mousemove", function(e) {
var $hovered = $(e.target);
var $myButton = $(".myButton");
var $box = $(".myBox");
if ( $hovered.is( $myButton ) ) return;
if ( $hovered.is( $box ) ) return;
if ( $.contains( $box.get(0), $hovered ) ) return;
$box.fadeOut();
});
...and similar for button2. The basic principle is this - whenever the mouse moves, we check whether the mouse is hovering over the button, or the box, or over an element contained in the box (using $.contains()). If not, we hide the box.

displaying a group of divs by clicking next and back buttons

I have 5 divs that contain copy.
I have a back and next button, to display each div.
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
// hide the divs, except the first one.
.vote-result { display: none; }
.vote-result.first { display: block; }
The first time the next button link is clicked, I want to remove the off class, to show it as clickable, I probably should disable the link initially too and re-enable it too.
$(".back-btn").removeClass("off");
Once I display the last div, I need to add the off class to the next-btn and disable it.
I thought about using a carousel js plugin to accomplish this, but it is overkill for now.
I know of a way to do this, but it would involve assigning subclasses to the links based on what next or back button was clicked, so it will know what div to show next, as well as removing or adding the off class to the links.
I am hoping to find a solution that allows me to add more div's to display without modifying the code. Any help is appreciated, thank you.

Here is solution for you. I have created Fiddle for your requirement.
HTML code:
<a class="back-btn off">Back</a> | <a class="next-btn">Next</a>
<div class="vote-result first selectedDiv">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result last">
this is the last div
</div>
JS/JQuery Code:
$(".back-btn").click(function(){debugger;
var prevElement=$('.selectedDiv').prev();
prevElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
prevElement.addClass("selectedDiv");
if($('.first').css('display')=="block"){
$(".back-btn").addClass("off");
}
else{
$(".next-btn").removeClass("off");
}
});
$(".next-btn").click(function(){debugger;
var nextElement= $('.selectedDiv').next();
nextElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
nextElement.addClass("selectedDiv");
if($('.last').css('display')=="block"){
$(".next-btn").addClass("off");
}
else{
$(".back-btn").removeClass("off");
}
});
CSS code:
.vote-result { display: none; }
.vote-result.first { display: block; }
.off{display:none;}

Your HTML file:
<html>
<head>
<style>
.vote-result { display: none; }
.vote-result.first { display: block; }
.off {
color: Red;
}
a {
color: blue;
}
</style>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="code.js"></script>
</head>
<body>
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
</body>
</html>
Your new "code.js" file in the same directory:
/**
* The zero-based index of the <div class="vote-result"> element that is currently being shown
* #var {Number}
*/
var activeIndex = 0;
function getNumberOfItems() {
return $('.vote-result').length;
}
function synchronizeInterface() {
var numberOfItems = getNumberOfItems(),
lastIndex = numberOfItems - 1;
$('.vote-result').removeClass('first');
$('.vote-result').each(function(index) {
if (index == activeIndex) {
$(this).addClass('first');
}
})
$('.back-btn').toggleClass('off', activeIndex == 0);
$('.next-btn').toggleClass('off', activeIndex == lastIndex);
}
$(function() {
$('.back-btn,.next-btn').on('click', function() {
// If the button clicked is not deactivated
if (!$(this).hasClass('off')) {
// Determine whether the "Next" button was clicked (otherwise "Back" was clicked)
var clickedNext = $(this).hasClass('next-btn');
// Move the active index in the appropriate direction while not allowing it to fall outside the boundaries of appropriate indices
activeIndex = clickedNext
? Math.min(activeIndex + 1, getNumberOfItems() - 1)
: activeIndex = Math.max(0, activeIndex - 1);
// Make sure the interface now reflects the updated JavaScript variables
synchronizeInterface();
}
return false;
});
});
Some notes: You had an unclosed double-quote for one of your class attributes in your provided HTML. Also, I added some additional styling -- you may want to rename the ".first" CSS class to ".active" instead.

take a look at jquerys .next() function for navigating - jQuery - Next(). you can also check for the last item like this.
if($(this).is(':last-child'))
{
$('.next-btn').removeClass('off');
}else{
$('.next-btn').addClass('off');
}
check everytime a navigation button is clicked and do the same for the first button

Hiding the closest div with the specified class

I'm working on an application in which mimics desktop style application windows that open, minimize and close. I've managed to get them to expand and collapse, but I am unable to get the to close, and I can't figure out why. I need to be able to close the current div by clicking a button, see code / eg. below.
<script>
$(document).ready(function () {
$("form.common").first().show();
$(".expand").click(function () {
$(this).parents().next("form.common").show();
})
$(".collapse").click(function () {
$(this).parents().next("form.common").hide();
});
$(".close").click(function () {
$(this).parents().next("div.module").hide();
});
});
</srcipt>
<div id="task_manager" class="module"> <!-- Need the x with class close to hide this div-->
<h3>Task Manager</h3> <!-- This header and below icons are shown when minimized-->
<div class="module_actions">
<span class="icons_small right close">X</span>
<span class="icons_small right collapse">-</span>
<span class="icons_small right expand">+</span>
</div>
<form class="common">
<fieldset>
<legend> Some Titlee/legend>
</fieldset>
</form>
</div>
Can anyone see why this is not hiding the div?
THanks,

The answer is in the question:
$(".close").click(function () {
$(this).closest("div.module").hide();
});
Demo fiddle
Also you should change your calls to parents() to just parent() so you just go up one level in the DOM tree

You had a missing < in <legend> Some Titlee/legend>, after that it works.
Check here

This should work :
$(".close").click(function () {
$(this).parent().hide();
});
