We need to be able to hide and show elements based on currently hovered element. We have tried the following below, but it does not add the is-active class and remove it based on what other element is on hover.
How can we hide and show elements based on the current hovered element?
Goal (based on example below):
when you hover over some under first, display <div class="two" id="some-link">some link</div> using is-active class
when you hover over path under first, <div class="two" id="some-link">some linke</div> should not display (remove is-active class), and <div class="two" id="path-link">path link</div> should display (add is-active class)
Current issue:
is-active class is not being removed when on hover element is changed
$(function() {
$('li#two').hover( function() {
var el_two = $(this);
var el_id = el_two.attr('id');
var el_link = el_two.attr('data-at');
var el_sel = '#'+el_link+'.'+ el_id;
var el_parent = el_two.parent().parent();
el_parent.find('.is-active').removeClass('is-active');
$(el_sel).addClass('is-active');
});
});
.two {
display: none;
}
.is-active {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li id="one">
first
<div class="one">
<ul>
<li data-at="some-link" id="two">
some
</li>
<li data-at="path-link" id="two">
path
</li>
<li data-at="another-one" id="two">
another one
</li>
</ul>
<div class="dropdown">
<div class="two" id="some-link">some link text</div>
<div class="two" id="path-link">path link</div>
<div class="two" id="another-one">another one</div>
</div>
</div>
</li>
<li id="one">

<div class="one">
<ul>
<li>

</li>

</li>
</ul>

First your .find() is using the wrong selector. You have find('is-active') which is an element name selector, you wanted a css class selector ie .is-active.
el_parent.find('.is-active').removeClass('is-active');
Note for removeClass() you don't use a css selector you just use a class name hence why you don't need the dot in that call
Now if you wanted to also have the class removed on hovering out of the element as well then you need to add an event listener for that, and call removeClass from there. .hover() uses a second argument for setting such an event listener callback.
$('li#two').hover(onHoverCallback,function(){
//code for finding the right element
$(el_sel).removeClass('is-active');
})
$(function() {
$('li#two').hover( function() {
var el_two = $(this);
var el_id = el_two.attr('id');
var el_link = el_two.attr('data-at');
var el_sel = '#'+el_link+'.'+ el_id;
var el_parent = el_two.parent().parent();
el_parent.find('.is-active').removeClass('is-active');
$(el_sel).addClass('is-active');
},function(){
var el_two = $(this);
var el_id = el_two.attr('id');
var el_link = el_two.attr('data-at');
var el_sel = '#'+el_link+'.'+ el_id;
$(el_sel).removeClass("is-active");
});
});
.two {
display: none;
}
.is-active {
display: block;

I am using handlebars to show data. I have a ul that filters the data and populates another ul. The filter ul has a couple of choices that currently output an empty ul. I want the empty ul to show a message that says "There are no sessions yet."
I am trying to use handlebars if helper. The problem I am running into is the message is showing up in all ul, even if it is not empty.
<div class="session-details-inner">
<div class="sidebar left-sidebar left-align">
<ul id="session_filter_15308050681959955093" class="session_filters no-list-style">

<script type='text/javascript'>
$(document).ready(function($) {
$('.accordion').on('click', function() {
$parent_box = $(this).closest('.accordion-panel');
//$parent_box.siblings().find('.panel').slideUp(500);

$(".session_filters a").click(function(){
jQuery(".session_filters a").removeClass("active");
jQuery(this).addClass("active");
currentSessionType=jQuery(this).attr("data-filter");
jQuery(".individual-session").hide();
jQuery(".individual-session[data-track='"+currentSessionType+"'").show();
individualSession = jQuery('.individual-session');
if(currentSessionType == 'All'){
jQuery(".individual-session").show();
}
});
});
</script>
If you want to check & conditionally render if there are no sessions, shouldn't you do the length check on your Sessions instead of the TrackDescription?
Added this snippet of jQuery to check if all li had a style of display: none. If all li have display: none, show message li else hide message li.
if($('.scheduleday_wrapper').children(':visible').length == 0){
jQuery(".no-sessions").show();
}
else{
jQuery(".no-sessions").hide();
}
First, my HTML tag is here
<ul>
<li>
<form>...</form>
<div>
<div class="A"></div>
<div class="B"><img class="wantToShow"></div>
</div>
<div class="C"></div>
</li>
<li>...</li>
</ul>
What I want to do is that when I mouse over <li>, the small image, <img class="wantToShow"> , is shown up(like hover).
But when I add event on each <li> element the following problems occur.
If I use jQuery.mouseover(<li>, function), the whole element in <li> shown up whenever I move mouse cursor in <li>.
If I use jQuery.mouseenter(<li>, function), an element, my mouse cursor enter at first, shown up. In this case, the real problem is that the event do not catch <li> but an element in <li>.
What can I do for this... Thank you!
I think something like this is what you are after:
$('li').on('mouseover',function() {
var $this = $(this);
if($('.wantToShow').is(':hidden')) {
$this.find('.wantToShow').show();
} else {
$this.find('.wantToShow').hide();
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>
<form>This is A</form>
<div>
<div class="A"></div>
<div class="B">
<img src='https://placebear.com/200/300' class="wantToShow">
</div>
</div>
<div class="C"></div>
</li>
<li>This is B</li>
</ul>
So essentially I am trying to find the value of an attribute, in this instance, 'data-location', and then search for that value elsewhere, in this instance in the form of an ID, and alter the CSS for that matched value.
I have the below so far which I thought would work, but I am not sure how to check for various different values for various elements and apply accordingly, so I have grouped the different sections in div's with classes so I can break them up from one another
Thanks guys
var getvalue = $('ul#test').find('li').attr('data-location');
if( $('div.other div').attr('id').val() == getvalue ) {
$( this ).css('background-color','red');
};
#thebirchplot3 {
padding:30px;
background:#fff;
}
#theashplot3 {
padding:30px;
background:blue;
color:#fff;
}
#thediveplot1 {
padding:30px;
background:yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<div id="thediveplot1">

You need to do it like below:-
Working Example:-
$('ul#test').find('li').each(function(){ // iterate over each li element
var ultest = $(this); //assign current li object to variable
$('div.other').children().each(function(){ // now iterate to each child div of other div
if($(this).attr('id') == ultest.data('location')){ // compare id with data-location
$( this ).css('background-color','red'); // if same then add background color
}
});
});
#thebirchplot3 {padding:30px;background:#fff;}
#theashplot3 {padding:30px;background:blue;color:#fff;}
#thediveplot1 {padding:30px;background:yellow;}

</ul>
<ul id="show">

<li>three</li>
</ul>
<ul id="display">

<li>two</li>
<li>three</li>
</ul>
------
<div>
<div class="other">
<div id="thebirchplot3">

</div>
<div id="thebirchplot355435">

<div id="theashplot3">

</div>
<div id="theashplot35465464">

</div>
<div id="thediveplot1">

</div>
</div>
</div>
use jquery find() method for your requirement as
var getvalue = $('ul#test').find('li').attr('data-location');
$('div.other').find('#'+getvalue).css('background-color','red');

I want to show the div of selected HTML link.
For example:
I clicked on the html link Categories the <div id="categories" ... > will be showed and the other div's will hide.
HTML
<div id="col-navigation">
<ul>
<li>
Quizzes
</li>
<li>
Categories
</li>
<li>
Jump
</li>
</ul>
</div>
<div id="quizzes"> //default showed
Quizzes!
</div>
<div id="categories" style="display:none">
Categories!
</div>
<div id="jump" style="display:none">
Jump!
</div>
Try this:-
$('#col-navigation a').click(function(){
$('#quizzes,#categories,#jump').hide();
$('#' + $.trim($(this).text()).toLowerCase()).show();
});
Fiddle
OR
$('#col-navigation a').click(function(){
$('#quizzes,#categories,#jump').show()
.not('#' + $.trim($(this).text()).toLowerCase()).hide();
});
Fiddle
$("#col-navigation a").click(function(e) {
var getText = $(this).text().trim().toLowerCase();
$("#"+getText).toggle().siblings().hide();
e.preventDefault();
});
use the above code to make it work.

You can use css :target, general siblings selector ~
:target {
display: block !important;
}
:target ~ div[id] {
display: none;
}
<div id="col-navigation">
<ul>
<li>

<li>
Categories
</li>
<li>
Jump
</li>
</ul>
</div>
<div>
<div id="categories" style="display:none">
Categories!
</div>
<div id="jump" style="display:none">
Jump!

I'm working on a responsive menu for a quite complex website. The horizontal menu collapses to a vertical one for smaller screens and I've used javascript to toggle the sub-menu items open/closed when clicked.The product section is the only sub-menu that has another sub-menu a level deeper and it's not quite working for it as only the third level items close again on click, but not the parent item.
Here's the code
<nav id="navigation">
<ul id="nav-list">
<li class="nav-list_item nav-about">About us
<div id="about-drop" class="dropdown">
<ul>
<li>....</li>
<li>....</li>
</ul>
</div>
</li>
<li class="nav-list_item nav-products">Products
<div id="prod-drop" class="dropdown">
<div id="subnav_products1" class='targetDiv'>
<div class="drop-section">
<h5 class="nav-title">Purpose</h5>
<ul>
<li>...</li>
<li>...</li>
</ul>
</div>
<div class="drop-section">
<h5 class="nav-title">Series</h5>
ul>
<li>...</li>
<li>...</li>
</ul>
</div>
</div>
</div>
</li>
</ul>
And the javascript :
if ($(window).width() <= 760) {
$('li.nav-list_item').click(function(){
$('li.nav-list_item').not(this).find('ul').hide();
$(this).find('ul').toggle();
});
}
I think it might be because when the parent item (products) is clicked the ul close as specified in the javascript but the nav-title items (Purpose/ Series) are still open and can't be closed. I've been trying to work this out but just can't get it to work that when the title items are being clicked the third level menu closes and when the parent item(Products) is clicked the title items close. Any suggestions?
First off, I do not know how to debug your code as what you provided is not a working example. Head over to Codepen and create a pen where we can reproduce the issues.
Apart from that it is possible to implement the navigation with css only using hidden radio buttons or active states.
$('li.nav-list_item a, .nav-title').on('click', function(e){
e.preventDefault();
var el = $(this);
el.parent().siblings().find('> .dropdown:visible, > ul:visible').toggle();
el.parent().find('> .dropdown, > ul').toggle();
});
#nav-list .nav-list_item {
display: block;
}
#nav-list .nav-list_item .dropdown{
display: none;
}
#nav-list .nav-list_item .dropdown .drop-section ul {
display:none;
}
