I'm trying to find the element using jQuery from the following html.
<ul class="gdl-toggle-box">
<li class="">
<h2 class="toggle-box-title"><span class="toggle-box-icon"></span>Volunteer Form</h2>
<div class="toggle-box-content" style="">
</div>
</li>
</ul>
What I'm looking to do is when the h2 is clicked find the li above the h2 add a class active to it. Tried a few different calls but no luck.
EDIT
The biggest issue is that there are multiple toggle boxes on a page so something like this works on pages with a single toggle but pages with multiple the result is they all open together.
var gdl_toggle_box = jQuery('ul.gdl-toggle-box');
gdl_toggle_box.find('li').each(function(){
jQuery(this).addClass('item');
});
gdl_toggle_box.find('li').not('.active').each(function(){
jQuery(this).children('.toggle-box-content').css('display', 'none');
});
gdl_toggle_box.find('h2').click(function(){
if( jQuery('.item').hasClass('active') ){
jQuery('.item').removeClass('active').children('.toggle-box-content').slideUp();
}else{
jQuery('.item').addClass('active').children('.toggle-box-content').slideDown();
}
});
You can use closest.
closest will match the first parent element that matches the selector traversing up the DOM tree.
Demo
$('h2.toggle-box-title').click(function(){
$(this).closest('li').addClass('active');
});
Try this.
$('h2.toggle-box-title').click(function(){
$(this).parent().addClass('newclass');
});
try this:
$('h2.toggle-box-title').click(function() {
$(this).parent('li').addClass('active');
});
On you click in the button you can use the event:
$("something").parent().find("h2.myClass");
// And if you want you can add class after you find you object
http://api.jquery.com/find/
Selecting an element's parent
In order to select an element parent, you can use the parent() function.
Try this:
$('h2.toggle-box-title').click(function() {
$(this).parent('li').addClass('active');
});
*to be more specific, you target the parent you would like to choose by specifying its selector
Check the jQuery API Documentation here
parent() - Get the parent of each element in the current set of matched elements,
optionally filtered by a selector.

I have a list of links, one has the class active.
On my next button click id like to remove the class from the current element and add it to the next only I cant seem to get it to add?
Ive made a fiddle to hopefully explain my problem, any help would be great, thanks
http://jsfiddle.net/h6D4k/
$('.next').click(function(){
$('ul.pagination').find('a.active').removeClass('active');
$('ul.pagination').find('a.active').next('a').addClass('active');
return false;
});
One of the jQuery most usable conveniencies is that its methods are (usually) chainable - in other words, they return the very object they are called from. So you can simply write this:
$('ul.pagination').find('a.active').removeClass('active').closest('li')
.next('li').find('a').addClass('active');
... as it's <li> elements that should be 'nexted', not <a> ones. But in fact, you shouldn't probably discard 'active' altogether if it's the last element in question:
var $a = $('ul.pagination').find('a.active'),
$li = $a.closest('li'),
$nextLi = $li.next('li');
if ($nextLi.length) {
$a.removeClass('active');
$nextLi.find('a').addClass('active');
}
This is actually what you want based on your html structure in you fiddle. http://jsfiddle.net/h6D4k/1/
$('ul.pagination').find('a.active').removeClass('active').parent()
.next().find('a').addClass('active');
Because once you've done this...
$('ul.pagination').find('a.active').removeClass('active');
There is no more a.active - the active classname has been removed from that element. So repeating the same selector...
$('ul.pagination').find('a.active')//...
... will select nothing.
Chain it all together instead.
$('ul.pagination').find('a.active').removeClass('active').next('a').addClass('active');
You have a second problem. According to the jQuery API for next(), it will:
Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.
You're not trying to get the following sibling:
<ul class="pagination">
<li><a class="one active" href="#">X</a></li>
<li><a class="two" href="#">X</a></li>
<li><a class="three" href="#">X</a></li>
</ul>
Next

You're trying to get the next <a> in the whole document. That's more challenging - and I'm not sure how to do it.
I would write it this way, preventing the action from doing anything on the last li as well.
http://jsfiddle.net/h6D4k/6/
$('.next').click(function(e){
e.preventDefault();
if ($("ul.pagination a.active").parent().is(":last-child")) return;
$('ul.pagination a.active').removeClass('active').parent().next().find("a").addClass('active');
});
You have two errors in your code:
Once removed, the active class can't be found anymore
your a tags are nested in li tags so next() doesn't work as you expect
To simplify things, you could attach the active class to the li tags.
Live demo: http://jsfiddle.net/h6D4k/7/
Code:
$('.next').click(function(){
$('ul.pagination').find('li.active').removeClass('active')
.next().addClass('active');
return false;
});
<div class="panels">
<div>
<h2>
Test
</h2>
</div>
<div class="inner_panel statict">
Test2
</div>
</div>
I want so that when people click on Test, Test2 appears. If not, they don't see Test2, How can I make that happen using jquery?
I tried the following but it does not work.
$('.inner_panel').hide();
$('.panels').click(function () {
$(this).closest('div .inner_panel').toggle();
});
I have multiple divs with class panels in the file, so I don't want click on Test affecting the other "panels."
closest method looks up in the DOM tree, not down. You can check it here. http://api.jquery.com/closest/
Maybe you should use .children('div.inner_panel') to get your element. children method allows you to get elements, that are a single level down the DOM. Check http://api.jquery.com/children/ fo details.
You have an extra space -> $(this).closest('div .inner_panel').toggle();
This should be: $(this).closest('div.inner_panel').toggle();
But .closest() is not going to work for you because it travels up the DOM tree and not up and then down to siblings etc.
I would do this:
$('.inner_panel').hide();
$('.panels').click(function () {
$(this).find('div.inner_panel').toggle();
});
See jsbin demo
$('.inner_panel').hide();
// Within .panels get the div's which contain an H2
var containers = $('.panels h2').closest("div");
// make them clickable
containers.click(function () {
// For the clicked panel, get the next element div which
// has the inner_panel class
$(this).next('div.inner_panel').toggle();
});
Hello I have some HTML that looks like this,
<div id="music_interests">
<ul class="interests">
<li >
<div class="interest inline">
<img src=""/>
<div class="interest_popup">
1 users have this interest.
Remove interest </div>
</div>
</li>
</ul>
When users clicks the remove button I need to select the parent div (in this case music_interests). How would I go about that?
I have tried doing the following,
$(this).parent().parent().parent().parent() but is there a more elegant way?
To complicate things futher I will not actually no the parents ID when in the app as the remove button occurs in 4 or 5 different areas on the page.
you should use closest()
$(this).closest('div#music_interests');
//find the nearest div with id "music_interests"
//if i omitted the id, it retrieves the div with class "interest_popup"
or parents()
$(this).parents('div:eq(1)');
//get ALL the ancestor divs (until it reaches root tag)
//since music_interests is just 2 levels up, use :eq(1)
If the ID of the DIV you want to remove is static you should only use the ID selector (not something like $("div#music_interests")) as the ID selector is directly mapped to the DOM function document.getElementsById which is pretty fast:
$("#music_interests").remove();
If the ID isn't static you could get the UL just like that:
$(function(){ //execute when page has been loaded
$(".remove").click(function(){ //attach click handler
var removeDiv = $(this).closest("ul").parent().remove(); //get next UL -> DIV is its parent
return false; //stop further processing of "click" event
});
});
if remove button always exist in ul tag (in all your 4 or 5 different areas) then you can use the following code.
$(this).closest("ul").parent()
in this case u don't even need to give id to DIV tags
I have a dropdown function that I need to work only on the div clicked, not all (I have 14+ of the same classes on the page that need to be displayed when a certain one is clicked)
At the moment my jQuery is as follows.
$('.qacollapsed').hide();
$('.qa').click(function () {
$('.qacollapsed').slideToggle();
$(this).toggleClass('active');
});
Of course, that is toggling all qacollapsed classes when there is 14 on the page (Q&A)
Is there a way for it to only drop down the one that is clicked?
the HTML
<div class="qa">
<h4 class="question"> </h4>
</div>
<div class="qacollapsed">
<p> </p>
</div>
It would be helpful to provide a snippet of HTML here, but I'll take a guess at the structure of your markup for now..
Instead of referencing all .qacollapsed elements, you need find elements that are close to the .qa that was clicked, e.g.:
$('.qa').click(function () {
$(this) // start with the clicked element
.find('.qacollapsed') // find child .qacollapsed elements only
.slideToggle();
$(this).toggleClass('active');
});
This will work if .qacollapsed is inside .qa - if not, you might need to use next (for siblings), or one of the other jQuery tree traversal methods.
Yo could find() it or use this as a context in the selector to choose only a descendent of the clicked object
$('.qa').click(function () {
$('.qacollapsed', this).slideToggle();
//You could do $(this).find('.qacollapsed').slideToggle();
$(this).toggleClass('active');
});
Check out the jQuery selectors and why not just use $(this)?
$('.qacollapsed').hide();
$('.qa').click(function () {
$(this).toggleClass('active').next().slideToggle();
});
Personally, I'd give all the divs IDs, the clickable bit being the ID of the question in the database for example, and the answer just being id='ID_answer' or something, then use jquery to slide in the div with the id corresponding to the link clicked, ie
Var showIt = $(this).attr('id') + '_answer'
$('.qacollapsed').not('#'+showIt).hide();
$('#'+showIt).slideToggle;
That will hide all the divs without that ID and show the required one.
Dexter's use of .next above looks simpler though, I've not tried that as being relatively new to jquery too.
i want to read all links in ".vm-video-title"-divs and post them each in the same div. So i made this script:
$('.vm-video-title').each(function(i) {//all divs
$(this).html($(this).html()+$("div.vm-video-title>a").text());//add to div the link
});
but i have the problem that it reads ALL the links of all divs and put them in one div.
example:
<div class="vm-video-title">Text1</div>
<div class="vm-video-title">Text2</div>
<div class="vm-video-title">Text3</div>
output:
Text1Text1Text2Text3
Text2Text1Text2Text3
Text3Text1Text2Text3
wanted output:
Text1Text1
Text2Text2
Text3Text3
You can select the <a> elements directly, and use the after()[docs] method to append the content of each after each one respectively.
$("div.vm-video-title > a").after(function() { return $(this).text(); });
This doesn't do a "destroy then recreate" of the existing elements like the html()[docs] method will.
Working example: http://jsfiddle.net/CCr9C/
This should do the job for you,
you need to find the div inside current element in the loop (el).
$('.vm-video-title').each(function(i, el) {
el = $(el);
el.html(el.html()+el.find("a").text());
});
in your code you are adding text() of all matching "a" tags in your divs (i.e. Text1Text2Text3)
You were almost there. Instead of : $("div.vm-video-title").text(), which gives you text inside any div with class vm-video-title, you need to find a tag inside current div and get text from it. We pass this as context for selecting a inside current div jQuery( selector, [context] )
$('.vm-video-title').each(function(i) {//all divs
$(this).html($(this).html()+$("a", this).text());
});
