Could some one please help with code.
I want to show the submenu only when submenu parent is clicked.
HTML
<ul>
<li>Item</li>
<li>Item
<ul class="sub-menu">
<li>Submenu</li>
<li>Submenu</li>
</ul>
</li>
<li>Item</li>
<li>Item
<ul class="sub-menu">
<li>Submenu</li>
<li>Submenu</li>
</ul>
</li>
<li>Item</li>
</ul>
So if you click on the parent submenu will show.
Here is fiddle link - http://jsfiddle.net/KhNCV/1/
$('.sub-menu').hide();
$("li:has(ul)").click(function(){
$("ul",this).slideDown();
});

OR
$('.sub-menu').hide();
$("li:has(ul)").click(function(){
$("ul",this).toggle('slow');
});

Here's your example working. It's unclear why you need the a tags, as you could use cursor: pointer in the CSS to make the li appear clickable. I'll assume you want to do some spiffy hovering on them in IE that's CSS only? If not, you could simplify by removing them.
Instead of doing hide() on .submenu, you should use CSS (parsed with DOM instead of onReady/load).
.sub-menu { display: none; }
And then here's you code to toggle the menus:
$('ul li a').click(function() {
$(this).parent().find('ul.sub-menu').toggle();
return false;
});
$('.sub-menu').hide();
$("a").click(function(){
$(this).parent().children("ul").toggle();
})
check out this link
http://jsfiddle.net/KhNCV/6/
$('li a').click(
function() {
$(this).next().slideToggle();
})
Try this
$(function(){
//Hide all the sub menus
$('.sub-menu').hide();
$("li:has(ul)").click(function(){
//Find the child ul and slideToggle
$(this).children("ul").slideToggle();
});
});

I have this code and when i press the link with a element i want to hide the ul with class name tab and show the ul with class tab-1 without hidding the both of ul elements.I have tried with jquery but with no success. The jQuery code is the following.
$("a").click(function() {
$(".tab").hide("slide", {direction: "left"}, "slow");
$(".tab-1").show("slide", {direction: "left"}, "slow");
});
How can i do it?
<ul class="tab">
<li>
Link 1
<ul class="tab-1">
<li>List 1</li>
<li>List 2</li>
</ul>
</li>
</ul>
You can't show a child of an element that is set to display:none. If parent is not displayed...anything inside parent can't be either
However you can set visibility:hidden on parent and visibility:visible on descendants
.tab {visibility:hidden}
.tab-1 {visibility:visible}
Note that this is very uncommon practice. It would help to have a better description of what you want to acheive
DEMO
Just hide all elements that match .tab > li > a.
Demo :
.tab, .tab ul {
list-style-type: none;
}
.tab > li > a {
display : none;
}
<ul class="tab">
<li>
Link 1
<ul class="tab-1">
<li>List 1</li>
<li>List 2</li>
</ul>
</li>
</ul>
I have a submenu like below:
<ul id="main-menu" class="" style="">
<li class="root-level has-sub">
Menu 1
<ul>
<li>Sub-menu 1</li>
<li>Sub-menu 2</li>
</ul>
</li>
<li>Menu 2</li>
<li class="root-level has-sub"> <!-- here -->
Menu 3
<ul>
<li class="root-level has-sub"> <!-- add class 'opened' here and -->
Sub-menu 3
<ul>
<li>Sub-sub-Menu 1</li> <!-- this -->
<li>Sub-sub-Menu 2</li> <!-- when user click this or -->
</ul>
</li>
</ul>
</li>
What I would like to have is, when I click to the child, it will add 'opened' class to parent and highlight the clicked element. My code only success on Menu 1 and failed on Menu 3.
Notice that, in Menu 3, there are 2 parents for Sub-sub-Menu 1 and Sub-sub-Menu 2. So my question is, if i click on Sub-sub-Menu 1 or Sub-sub-Menu 2 it will highlight and add 'opened' class to 2 parents li above.
Note: I try to implement unlimited level of menu
Here is my full code Fiddle
I think you should use a different selector(for the click event). Look for all li>a pairs, corresponding to the submenu items, inside your #main-menu list
$('#main-menu li>a').click(function (e) {
e.preventDefault();
$('.active').removeClass('active');
$('.opened').removeClass('opened');
$(this).parent('li').addClass('active').parents('.root-level').addClass('opened');
//------------------------------------------------------^-----------------------------
// selects all parents with the 'root-level' class
});
Modifying the css to:
#main-menu .active {
background-color:#df0000;
color:#fff;
}
DEMO
you simply use the not: attribute in your closest() method to exclude all classes root-level
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
//we search for the first ancestor of this which is a li
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$('.active:first').closest('ul').addClass('opened');
});
});
check the link http://jsfiddle.net/GEj4z/11/
If I understood correctly what was desired was being able to produce a menu like behavior and it is because of that I would like to present an alternate solution:
Sample Fiddle
$('#main-menu').on('click','li:not(.root-level)',function(e){
$('.parent').removeClass('parent');
$('.selected').removeClass('selected');
$(this).parents('li.root-level').children('a').addClass('parent');
$(this).children('a').addClass('selected');
});
In this solution the parent menus are highlighted and the clicked item is marked as selected again I wanted to share my POV of this problem. I hope it helps.
Inside your click event use $(this).parents('li') to get the top level parent li of the clicked element. I hope this helps.
I found the solution! my jquery is:
$(function () {
$('ul#main-menu li ul li').click(function (e) {
e.preventDefault();
$(this).closest('li:not(".root-level")').addClass('active').siblings().removeClass('active');
$(this).parents('li').addClass('opened');
$(this).closest('li:has(".root-level")').removeClass('active');
});
});
Here is my full code JSFiddle
I have a navigation from a ul, see below:
<nav>
<ul>
<li>Top Link 1</li>
<li>Top Link 2</li>
<ul>
<li><a href="#" >Sub Link 1</a></li>
<li>Sub Link 2</li>
<li>Sub Link 3</li>
</ul>
</li>
<li>Top Link 3</li>
<ul>
<li><a href="#" >Sub Link 1</a></li>
<li>Sub Link 2</li>
<li>Sub Link 3</li>
</ul>
</li>
</ul>
</nav>
I have my css, hiding the the sub link's "ul" unless hovering the parent "li". (Will not show unless asked, as this is not the issues)
I'm trying to use my JQuery to add a css style (margin-bottom:30px;) to the top level "li" only if it has a child "ul" nested in it. My JQuery is as below:
<script>
$(document).ajaxSuccess(function () {
if ($("nav ul >li").children("ul li")) {
$("nav ul >li").hover(function () {
$("nav ul >li").css("margin-bottom", "30");
});
}
});
</script>
This does not appear to be working for me, can anyone point out what I'm doing wrong? Or can they provide a better solution to this approach?
.children will always return an array, check .length
$(document).ajaxSuccess(function () {
if ($("nav ul >li").children("ul li").length > 0) {
$("nav ul >li").hover(function () {
$("nav ul >li").css("margin-bottom", "30");
});
}
});
Try a little something like this :
$('li > ul').each(function(){
$(this).parent().addClass("your class");
});
This will select all uls that are children of li's and apply the class to the respectful li.
you do have an extra </li> in your question which i think is a typo..
<li>Top Link 2</li>
//-------^^^^^here
<ul>
<li><a href="#" >Sub Link 1</a></li>
anyways you check check for length of children if present..
try this
$(document).ajaxSuccess(function () {
if ($("nav ul >li").children().length > 0) {
$("nav ul >li").hover(function () {
$(this).css("margin-bottom", "30");
});
}
});
.children() method returns an object and an object is a truthy value in JavaScript, apart from that if the condition is valuated to true, you are adding a listener to all the li elements not just those that have ul children, You can use .has() method which is a filtering method:
$("nav > ul > li").has('ul').on({
mouseenter: function() {
$(this).css("margin-bottom", "30px");
},
mouseleave: function() {
$(this).css("margin-bottom", "n");
}
});
Or:
li.hovered {
margin-bottom: 30px;
}
$("nav > ul > li").has('ul').on('mouseenter mouseleave', function(e){
$(this).toggleClass('hovered', e.type === 'mouseenter');
});
I got the following structure: - nested UL
<ul>
<li>Category 1
<ul>
<li> Category 1.1</li>
<li> Category 1.2</li>
<li> Category 1.3</li>
</ul>
</li>
<li> Category 2
<ul>
<li>Category 2.1</li>
<li>Category 2.2</li>
<li>Category 2.3</li>
</ul>
</li>
<li>Category 3
<ul>
<li>Category 3.1</li>
<li>Category 3.2</li>
<li>Category 3.3</li>
</ul>
</li>
I've applied a rule with CSS:
ul{
list-style: none;
padding:0;
margin:0;
}
ul ul{
display:none;
}
which leaves only the MAIN category shown.
What i was trying to do is, whenever a user clicks on the Category 1/2/3, its <ul> will be visible. I've tried this code:
$(document).ready(function() {
$("ul li").click(function() {
$(this + "ul").Slidedown(800);
});
});
well, basically I was trying to select the <ul element that was inside the main <ul>.
How do I do it?
Try this.
$(document).ready(function() {
$("ul li").click(function() {
$(this).find('ul').Slidedown(800);
});
});
Given your selector, click on Category 1.1 will also call the callback, but it won't do anything since it doesn't have any ul tags. Still, it's better to add a class and bind the event only on those.
this is not a string, it's a DOM element.
Instead of $(this + "ul"), you want $('ul', this).
P.S. .Slidedown should be .slideDown.
$(this).find('ul:hidden').slideDown(800);
something like this should work
$(document).ready(function() {
$("ul > li").click(function() {
$(this).find("> ul").Slidedown(800);
});
});
Although, an even more efficient approach(thanks to Ian) would be:
$(document).ready(function() {
$("ul").children('li').click(function() {
$(this).children("ul").Slidedown(800);
});
});
using the '>' operator tells jquery to only look for direct children, if you don't use '>' the code will apply to the li elements inside the nested ul as well. also, read the other answers info about using 'this' properly.
You're concatenating the DOM element with "ul" to a string - that's not a valid selector. Instead, use .find() to apply the ul selector in the context of the current element.
$(document).ready(function() {
$("ul li").click(function() {
$(this).find('ul').Slidedown(800);
});
});
And maybe make the ul li selector a bit more specific to match only the outer list items.
I plan to apply a custom show/hide effect on link, such that when a user hovers on a link, a different link appears in its place. I'm not so good in javascript and here is what I was trying:
<div id="nav">
<li id="a1">hover link 1</li>
<li id="a2">show link 1</li>
<li id="b1">hover link 2</li>
<li id="b2">show link 2</li>
<li id="c1">hover link 3</li>
<li id="c2">show link 3</li>
</div>
The javascript:
$("#nav a.li").hover(function () {
(this.id.charAt(0)+"1").hide();
});
Here is the fiddle
You missed $ and need to add # befor id your also need to change selector as you do not have anchor with class li
Change
(this.id.charAt(0)+"1").hide();
to
$('#' +this.id.charAt(0)+"1").hide();
Your code would be
Live Demo
$("#nav a li").hover(function () {
$('#'+ this.id.charAt(0)+"1").hide();
});
Edit If you want to remove the item being hovered then use $(this)
Live Demo
$("#nav a li").hover(function () {
$(this).hide();
});
