hide all but one element of certain class in Jquery

I am trying to create an effect whereby clicking on a title toggles the corresponding content div. Clicking on another title while some content is showing should hide that content div and show the content div corresponding to the title just clicked.
However the code is not doing anything, as you can see on the following jquery: http://jsfiddle.net/dPsrL/
Any ideas?
HTML:
<div class="row title">
<div class="title" industry_id="education">Ed</div>
<div class="title" industry_id="tech">Tech</div>
<div class="title" industry_id="finance">Fin</div>
</div>
<br>
<br>
<div class="row content">
<div class="content" id="education">Education is great</div>
<div class="content" id="tech">Technology is awesome</div>
<div class="content" id="finance">Finance is super</div>
</div>
JAVASCRIPT:
$(document).ready(function () {
$('.content').hide();
});
('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$("#"+clicked).toggle(400);
$("#"+clicked).siblings().hide();
});

Instead of toggling the clicked element first and then hiding the others, why don't you just hide everything first and then show the clicked one? Saves you a check, and all you have to do is switch the order
$('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$('.content').hide();
$('#' + clicked).show(400);
});

Your attribute doesn't have the id selector in it. You need to do a string concatenation :
$('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$('#' + clicked).toggle(400);
$('#' + clicked).siblings().hide();
//The two last lines could be :
//$('#' + clicked).toggle(400).siblings().hide();
});
Also you have to remove the class content and title on the row since it trigger the click event and the hide part.
Here's a working fiddle : http://jsfiddle.net/dPsrL/3/

Typo on ('.title'). Should be $('.title'). Also, you should probably not give the container divs the same class as the child divs and then use that same class in your CSS and jQuery. It just makes selection more difficult.

Jquery Slidedown First

I'm working with someone else html else I would of approached this differenty, but I'm trying to create a simple accordion from it.
The problem is it only slides show the first lot of div, it should find its parent div and slide show.
JS
$('h3.jqueryheading').click(function() {
$(this).parent().find('div:first').slideToggle( "slow", function() {});
});
HTML
<h3 class="jqueryheading" style="cursor:pointer">Heading One</h3>
<div style="display:none;">
<p><img src="one.jpg"/></p>
<p><img src="two.jpg"/></p>
</div>
<h3 class="jqueryheading" style="cursor:pointer">Heading Two</h3>
<div style="display:none;">
<p><img src="three.jpg"/></p>
<p><img src="four.jpg"/></p>
</div>
Any ideas why this is happening?

Targeting the parent, then all DIV's gets you all the DIV's as they are children of the same parent, just target the next() DIV instead
$('h3.jqueryheading').click(function () {
$(this).next('div').slideToggle("slow");
});
FIDDLE

You can use next to target the next element
$('h3.jqueryheading').click(function() {
$(this).next().slideToggle( "slow", function() {});
});
Or the next div tag, if you want to be specific
$('h3.jqueryheading').click(function() {
$(this).next('div').slideToggle( "slow", function() {});
});
FIDDLE

Only one issue you have to use the :first-child or :eq(0)
$('h3.jqueryheading').click(function() {
$(this).parent().find('div:eq(0)').slideToggle( "slow", function() {});
});

jQuery hovering a cloned item

I got some HTML structure like this:
<div id="mobileWrapper" class="ios">
<div class="hoverWrapper">
<div class="acvCouponPreviewWrap clearfix">
<div class="previewLeft">
<span class="previewLeftInner"> 10% </span>
</div>
<div class="previewRight">
<span class="previewUser"> Some Text here </span>
</div>
</div>
<!-- clone will placed here -->
</div>
<div class="hoverWrapper">
<div class="acvCouponPreviewWrap clearfix">
...
</div>
<!-- clone will placed here -->
</div>
<div class="hoverWrapper">
<div class="acvCouponPreviewWrap clearfix">
...
</div>
<!-- clone will placed here -->
</div>
</div>
Now when I'am hovering the .hoverWrapper Items, I want to clone the hovered Item and place it bigger over the hovered Item. Okay, so far this is working. Problem here is a flickering effect while hovering. Some help would be gracefull!
http://jsbin.com/oJeDUmU/2/edit
I tried this, but does not what I want:
if ($(this).parent().find('.hoverWrapper')) {
if ($(this).find('.previewActive')) {
return false;
}
}

It's because you're inserting the cloned item outside of the .hoverWrapper. The instant you move your mouse the script detects that you're no longer hovering over it so it removes the clone. Then it detects you're hovering again so it inserts it again, then detects it again, and so on.
All you have to do is insert the clone inside the wrapper.
hoveredItem.before(cloneItem);
//change to this line
hoveredItem.append(cloneItem);
http://jsbin.com/oJeDUmU/4/edit

The flickering is caused by the fact that, as soon as you display the cloned item, you hover out of the original item. Then the clone disappears, and you've hovered in again.
You can fix this by changing your code so that you mouseenter the original element but mouseleave the clone:
$(document).ready(function () {
$("div.hoverWrapper").on('mouseenter', function () {
console.log('enter');
var hoveredItem = $(this);
var position = hoveredItem.offset().top - $('#mobileWrapper').offset().top - hoveredItem.height() / 2;
var cloneItem = $(this)
.clone()
.addClass('previewActive')
.css('top', position)
.css('left', '-34px')
.on('mouseleave', function () {
console.log('leave');
$(this).fadeOut(300, function () {
$(this).remove();
});
$(this).remove();
});
$('#mobileWrapper').find('.previewActive').remove(); // remove other boxes
hoveredItem.before(cloneItem);
});
});

JS slidetoggle on UL Tree

When i click on second item with slideToggle, first item close.
$(function() {
$('.toggleSitemap').find('ul').css('display','none')
$('.toggleSitemap').click(function(){
$(this).parent().find('ul').slideToggle('slow');
});
});
http://jsfiddle.net/qHZsZ/2/

I dont know how much will this help you. I also needed to implement accordian(toggle) in my MVC project once, and I used something like this:
View.aspx:
<div class='toggle' style="float: left">
<div style="float: left;clear:both;">
<br />
<span class="ulGroup" jqattr="<%:Group.Key %>" style="font-weight: bold;font-color: black;cursor: pointer"><img src="<%: Url.Content("~/Images/imageplus.gif")%>"/>
<%:Group.Key%></span>
</div>
<div class="togglebox" style="clear:both;" >
<!-- Write contents as you wish -->
<!-- as
<ul> test
<li>Test1></li>
<li>Test2></li>
<li>Test3></li>
</ul>
.
.
.
-->
</div>
</div>
And called a design.js (javascript file) as :
$(document).ready(function () {
//Hide the tooglebox when page load
$(".togglebox").hide();
//slide up and down when click over span
$(".ulGroup").click(function () {
var valueText = $(this).attr('jqAttr');
// slide toggle effect set to slow you can set it to fast too.
var x = $(this).parent().next(".togglebox").css("display");
if (x == "block") {
$(this).text('');
$(this).append($('<img src="../../Images/imageplus.gif"/>'))
$(this).append(' ' + valueText);
}
else {
$(this).text('');
$(this).append($('<img src="../../Images/imageplus.gif"/>'))
$(this).append(' ' + valueText);
}
$(this).parent().next(".togglebox").slideToggle("fast");
return true;
});
});

You're pretty close. I think the key ingredient you're missing is to prevent propagation of the click event.
Also, to make it a little less quirky, you only want the click event to fire if the target's direct parent has the toggleSitemap class.
$(function() {
$('.toggleSitemap').click(function(e){
if ($(e.target).parent().hasClass('toggleSitemap')) {
e.stopPropagation();
$(this).children('ul').slideToggle('slow');
}
});
});

jquery expand / collapse?

Im trying to make my jquery expand when clicked anywhere ( except the top left box ) and try to collapse when clicking only in the ( top left box )
http://jsfiddle.net/wzbAh/1/
HTML:
<div id="box">
<div class="collapsed container" >
<div class="nav" class="closed">0</div>
box 1 - click me
<div class="expanded_content">
extra content only for expanded state
</div>
<div class="collapsed_content">
collapsed only content #1
</div>
</div>
<div class="collapsed container">
<div class="nav" class="closed">0</div>
box 2 - click me
<div class="expanded_content">
extra content only for expanded state
</div>
</div>
<div class="collapsed container">
<div class="nav" class="closed">0</div>
box 3 - click me
<div class="expanded_content">
extra content only for expanded state
</div>
</div>
</div>
JavaScript:
$("#box").delegate(".container", "click", function(e) {
$(this).addClass("expanded");
});
$("#box").delegate(".container.expanded .nav ", "click", function(e) {
$(this).addClass("collapsed");
});
Seems to be almost there but not quite, what would be the right way to do it? Since toggle seems not the option here.

Here you go mate...
$("#box").delegate(".container", "click", function(e) {
if ($(e.target).hasClass("container")) {
$(this).addClass("expanded");
}
});
$("#box").delegate(".container.expanded .nav", "click", function(e) {
$(this).parent().removeClass("expanded");
e.stopPropagation();
});
​
The class "collapsed" is never removed so to remove the expanded state you need to use removeClass("expanded"), so it goes back to its initial state. Also, when the .nav element is clicked, the div you want to affect is the parent.
Finally, e.stopPropagation() stops the click firing both event handlers and removing the class and then adding it again.
Here's a working jsfiddle...
http://jsfiddle.net/wzbAh/11/

$("#box").delegate(".container", "click", function(e) {
if (!$(e.target).is("div.nav")) {
$(this).addClass("expanded");
}
});
$("#box").delegate(".container .nav ", "click", function(e) {
$(this).parent().removeClass("expanded").addClass("collapsed");
});
