I'm trying to figure out a function that will allow me to hide divs and show them if referring link is clicked.
Hard to explain but here is what I am looking for:
<ul>
<li>Link 1</li>
<li class="active">Link 1</li>
<li>Link 1</li>
<ul>
<div id="id-1">Some content</div> // Hidden
<div id="id-2">Some content</div> // This should only show in document
<div id="id-3">Some content</div> // hidden
Whenever other anchor is being clicked other divs should hide.
I hope his make sense and thank you for your help in advance
Dom
You can use something like this (untested so may need tweaking):
$(document).ready(function() { //fires on dom ready
$("a").click(function(e) { //assign click handler to all <a> tags
$(".classForYourDivs").hide(); //hide all divs (put class on ones you want to hide)
var element = $(e.target);
var href = element.attr("href"); //get the attribute
$(href).show(); //show the relevent one
return false; //important to stop default click behavior of link
});
});
Incidentally you should consider using something other than the href to store this information... take a look at the docs for the jquery data() function
Add a class to the ul and the divs.
<ul class="myUL">
<li>Link 1</li>
<li class="active">Link 1</li>
<li>Link 1</li>
<ul>
<div id="id-1" class="myDivs">Some content</div> // Hidden
<div id="id-2" class="myDivs">Some content</div> // This should only show in document
<div id="id-3" class="myDivs">Some content</div> // hidden
then in CSS,
.myDivs { display: none; }
and Try below js code,
var $myDivs = $('.myDivs');
$('.myUL a').on('click', function () {
$myDivs.hide();
$($(this).attr('href')).show();
});
DEMO: http://jsfiddle.net/LYKVG/
$("body").on("click","a", function(){
var divtoshowselector = $(this).attr("href");
$(divtoshowselector).show().siblings().hide();
})

html
<ul>
<li>Link 1</li>
<li class="active">Link 2</li>
<li>Link 3</li>
<ul>
<div id="id-1">Some content 1</div>
<div id="id-2">Some content 2</div>
<div id="id-3">Some content 3</div>
css
div {display: none;}
javascript/jquery
$("a").click( function(e) {
e.preventDefault();
var elId = $(this).attr('href');
$('div').hide();
$(elId).show();
});
I've set up a fiddle for you, check out: http://jsfiddle.net/UsGag/
function currentActive()
{
return $("li.active a").attr("href");
}
$("div:not(" + currentActive() + ")").hide();
$("li a").on("click", function()
{
//hide old active div
$("div" + currentActive()).hide();
$("li").removeClass("active");
//activate new div
$(this).parent().addClass("active");
$("div" + currentActive()).show();
});
Hope this helps you, extend to your own needs. And just for completeness: Don't use the - in ids / classnames.
Try
$("a").click( function( ) {
var elId = $(this).attr("href");
$(elId).show().siblings("div[id^=id-]").hide();
});

I have three div elements:
<div class="hide_banner" id="1"><img src="1.png"></div>
<div class="hide_banner" id="2"><img src="2.png"></div>
<div class="hide_banner" id="3"><img src="3.png"></div>
After the page is loaded the user should see the 1st div only. Here is the JS/jQ code (this works perfectly):
$(document).ready(function() {
$('.hide_banner').not('#' + 1).hide(3000);
});
The user can pick another banner by click at links on this page:
<ul class="dropdown-menu" role="menu">
<li>Image 1</li>
<li>Image 2</li>
<li>Image 3</li>
</ul>
After click for example on the 3rd link (href="#3") the div with id="1" should hide and the div with id="3" shold be shown. I have an idea how to maintain the problem combaining with PHP, but i want to solve it with JS/jQ only, so please help! ;) Here is my JS/jQ code which doesn't work:
$(document).ready(function() {
$('.hide_banner').not('#' + 1).hide(3000);
$('a').click(function() {
var id = $(this).attr('href');
if(id == 1) {
$(id).show(3000);
$('#2').hide(3000);
$('#3').hide(3000);
}
if(id == 2) {
$(id).show(3000);
$('#1').hide(3000);
$('#3').hide(3000);
}
if(id == 3) {
$(id).show(3000);
$('#1').hide(3000);
$('#2').hide(3000);
}
});
});
P.s.: I know that it is incorrect to start id's names with a number ;)
Really, no need for if...else logic here, nor any need to specify the first id - just use :first:
$('.hide_banner').not(':first').hide(3000);
$('a').click(function() {
var id = $(this).attr('href');
$(id).show(3000);
$('.hide_banner').not(id).hide(3000);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="hide_banner" id="1">1</div>
<div class="hide_banner" id="2">2</div>
<div class="hide_banner" id="3">3</div>
<ul class="dropdown-menu" role="menu">
<li>Image 1</li>
<li>Image 2</li>
<li>Image 3</li>
</ul>
You already know how to use jQuery not, so use it to exclude the selected target:
JSFiddle: http://jsfiddle.net/vk94mmv2/2/
$(document).ready(function () {
$('.hide_banner:not(:first)').hide(3000);
$('a').click(function () {
var id = $(this).attr('href');
var $show = $(id);
$show.show(3000);
$('.hide_banner').not($show).hide(3000);
});
});
Note: you can change the first selector to use the :not(:first) pseudo selectors to select all but the first banner.
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();
});
html structure:
<div class="row">
<div class="span"></div>
<div class="span"></div>
<div class="navMenu">
<ul>
<li>Link 1</li>
<li>Link 1</li>
</ul>
</div>
</div>
Then I am adding a "new" div just after the above html:
<div class="row">
<div class="span"></div>
<div class="span"></div>
<div class="navMenu">
<ul>
<li>Link 1</li>
<li>Link 1</li>
</ul>
</div>
</div>
<div class="new"></div>
$(".navMore li a").each(function() {
$(this).on("click", function() {
$('<div class="new"></div>').insertAfter($(this).closest('.row'));
$('<div class="span"></div>').appendTo('.new');
});
});
Finally I need to check if a div with class .new exists RIGHT AFTER the div containing the menu, and if so add a .span div in it, and if a div with class .new doesn't exist, then create it and then insert a div with class .span in it:
$(".navMore li a").each(function() {
$(this).on("click", function() {
if($(this).next().hasClass("new")){
$('<div class="span"></div>').appendTo('.new');
}
else {
$('<div class="new"></div>').insertAfter($(this).closest('.row'));
$('<div class="span"></div>').appendTo('.new');
}
});
});
It is IMPORTANT that the new div with class .new is a div with such a class right next the div container the menu. The reason why is because I will many menus with many different .row divs, so I wanted to target the correct one.
The above final code doesn't work tho
You don't need the each loop - also you notice how .new and .row are siblings?
$(".navMore li a").on("click", function() {
var $el = $(this);
var $row = $el.closest('.row'); // <-- get to row first
if($row.next('.new').length){ // check next element
$('<div class="span"></div>').appendTo('.new');
}
else {
$('<div class="new"></div>').insertAfter($row);
$('<div class="span"></div>').appendTo('.new');
}
});
You also have your classes mixed up.. So you need to make sure they match
<div class="navMenu"> <!-- <-- here -->
<ul>
<li>Link 1</li>
<li>Link 1</li>
</ul>
</div>
and
$(".navMore li a") // <-- here
The foreach loop is unnecessary. You can just bind a click event to all the items in a selector directly rather than looping through a set and binding them individually.
I would bind the click event to the .row divs since the click event will bubble up ... this will make your selectors very easy to test if the next sibling has a .new class.
$('.row').click(function() {
var newDiv = $(this).next();
if(newDiv.hasClass('new')){
$('<div class="span"></div>').appendTo(newDiv);
}
else {
newDiv = $('<div class="new"></div>');
newDiv.insertAfter($(this));
$('<div class="span"></div>').appendTo(newDiv);
}
});
Edit:
The reason why I chose to bind to the .row is because part of the DOM rules about how events propagate up to their parents says that if someone clicks an Anchor tag then it will send the event up the parents in the DOM. So this means that if we are listening for a click on a parent of an tag, it will appear as if the click came from that said parent (in this case, a .row div).
$(".navMenu ul li a").on("click", function () {
if ($(this).closest('.row').next('.new').length) {
$('<div class="span"></div>').appendTo('.new');
} else {
$('<div class="new"><div class="span">This is a span.</div></div>').insertAfter($(this).closest('.row'));
}
});
i am having some trouble with the menu bar on this website: http://www.re-generation.ro/ro/campanii/minerit-aurifer .
Now, the second li element is active. What i want to do, is that on hover over any other li element in the menu, the class of the current active li element becomes blank and on on hover out, it becomes active again. If you visit the link you can easily understand what i what.
If you need any information pls ask.
thank you in advance!
My code:
var lis = document.getElementsByTagName('ul');
for (var i=0, len=lis.length; i<len; i++){
lis[i].onmouseover = function(){
var firstDiv = this.getElementsByTagName('li')[1];
firstDiv.className = '';
var ul = $(this).parent(document.this.getElementsByTagName('ul')[1]);
ul.className = '';
};
lis[i].onmouseout = function(){
var firstDiv = this.getElementsByTagName('li')[1];
firstDiv.className = 'active';
};
};
EDIT: Thank you all for your answers! That really helped!
The first thing you probably want to do is assign two different states/classes: active and current. One tells you which one should be shown, and the other actually toggles the visibility.
$('#menu').on('mouseover', '> li', function(e) {
# attach hover event to the menu, and check which LI you are hovering
if (!$(this).hasClass('.current)')) {
$('.current', '#menu').removeClass('active');
}
}).on('mouseout', '> li', function (e) {
if (!$(this).hasClass('.current)')) {
$('.current', '#menu').addClass('active');
}
});
Here you are selecting just the direct descendants and updating the class, provided it's not the currently active list item.
HTML:
<ul id="menu">
<li>Item 1</li>
<li class="current active">Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
JavaScript:
$('#menu li').on('mouseover', function() {
var li$ = $(this);
li$.parent('ul').find('li').removeClass('active');
li$.addClass('active');
})
.on('mouseout', function() {
var li$ = $(this);
li$.removeClass('active');
li$.parent('ul').find('li.current').addClass('active');
});
DEMO
I would use JQuery for this. Something like this:
$('li').hover(function(){
$('li.active').removeClass('active').addClass('normal');
});
$('li').mouseleave(function(){
$('li.normal').removeClass('normal').addClass('active');
});
What you're missing is a way to remember what the default state is. Here is my answer, and a Fiddle
HTML:
<ul class="menuWithDefault">
<li>Link One</li>
<li class="active">Link One</li>
<li>Link One</li>
<li>Link One</li>
</ul>
Javascript:
$(".menuWithDefault").each(function() {
var defaultItem = $(this).find(".active").first();
$(this).find("li").hover(function() {
defaultItem.toggleClass('active', false);
$(this).toggleClass('active', true);
}, function() {
$(this).toggleClass('active', false);
defaultItem.toggleClass('active', true);
});
});
$(document).ready(function(){
$('li').hover(function(){
$(this).addClass('active').siblings().removeClass('active')
});
});
li.active{
color:red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li class="active">List Item 1</li>
<li>List Item 2</li>
<li>List Item 3</li>
<li>List Item 4</li>
</ul>
I have attached a snippet of my HTML.
Is it possible if I hover over the hyperlink with ID li1link that div#li1 is displayed, and if I hover over the hyperlink with ID li2link then div#li2 is displayed. Is this easily achievable?
So I guess the default is the DIVs are set to display:hidden until that particular related link is hovered over/active.
To confirm, only one DIV will be visible at any time.
Here is my current HTML:
<ul>
<li>Test 1 - hover over to display ul#li1</li>
<li>Test 2 - hover over to display ul#li2</li>
</ul>
<div id="li1">
<ul>
<li>Content 1</li>
<li>Content 1</li>
</ul>
</div>
<div id="li2">
<ul>
<li>Content 2</li>
<li>Content 2</li>
</ul>
</div>
I'm open to using jQuery or CSS, I'm just not totally sure how to approach this issue. Confused is an understatement.
Many thanks for any pointers with this.
You could try:
// for all links that have link keyword in their ids
$('a[id*="link"]').mouseenter(function(){
// get the div id out of this
var id = this.id.replace('link', '');
// hide all other divs
$('div[id^="li"]').hide();
// show the needed div now
$('#' + id).show();
});
// hide when mouse moves away
$('a[id*="link"]').mouseout(function(){
var id = this.id.replace('link', '');
$('#' + id).hide();
});
To confirm, only one DIV will be visible at any time.
These lines take care of that:
$('div[id^="li"]').hide();
// show the needed div now
$('#' + id).show();
$("#li1link).hover(function(){
$("#li1").attr('display','block');
});
$("#li1link).mouseover(function(){
$("#li").attr('display','none');
});
You can do similar thing when #li2link and display #li2 and hide it.
try this:
<!DOCTYPE html>
<html>
<head>
<script>
var p = {
onmouseover: function(link) {
document.getElementById(link.id.substring(0, 3)).style.display = "block";
},
onmouseout: function(link) {
document.getElementById(link.id.substring(0, 3)).style.display = "none";
}
};
</script>
</head>
<body>
<ul>
<li>Test 1 - hover over to display ul#li1</li>
<li>Test 2 - hover over to display ul#li2</li>
</ul>
<div id="li1" style="display: none;">
<ul>
<li>Content 1</li>
<li>Content 1</li>
</ul>
</div>
<div id="li2" style="display: none;">
<ul>
<li>Content 2</li>
<li>Content 2</li>
</ul>
</div>
</body>
</html>
You can check it here
CSS:
#li1link, #li2link {
display: none;
}
jQuery:
$("#li1, #li2").hover(
function () {
$('#' + $(this).attr('id') + 'link').show();
},
function () {
$('#' + $(this).attr('id') + 'link').hide();
});
With a minor html change (adding a class to your ul) you can handle it all in 1 function,
Assumption: The a->href value and the div ID are same.
DEMO
HTML Change:
<ul class="showDivOnHover">
<li>Test 1 - hover over to display ul#li1</li>
<li>Test 2 - hover over to display ul#li2</li>
</ul>
JS:
$('.showDivOnHover a').hover (function() {
$($(this).attr('href')).show();
}, function () {
$($(this).attr('href')).hide();
});
I used jQuery, tried to give you a quick solution:
http://jsfiddle.net/88nKd/
<ul id="nav">
<li>Test 1 - hover over to display ul#li1</li>
<li>Test 2 - hover over to display ul#li2</li>
</ul>
<div id="li1" class="none">
<ul>
<li>Content 1</li>
<li>Content 1</li>
</ul>
</div>
<div id="li2" class="none">
<ul>
<li>Content 2</li>
<li>Content 2</li>
</ul>
</div>
css:
.none{
display:none;
}
js:
$(document).ready(function(){
$(".liLink").mouseover(function(){
var linkNumber = $(this).attr('id');
var divNumber = '#li'+linkNumber;
$(divNumber).show();
}).mouseout(function(){
var linkNumber = $(this).attr('id');
var divNumber = '#li'+linkNumber;
$(divNumber).hide();
});
});
Cheers!
I find having a class which deals with the styles and then adding and removing those works well for me, so:
(Please note the below code will remove the class when not hovering over the link and I would recommend giving the links sensible class names to do the selector on rather than all a tags, same with the divs)
CSS:
div {
visibility:hidden; // Or display:none; or left: -999em; depending on what your page is there for.
}
div.show {
visibility: visible;
}
JS:
$('a').hover(function() {
$($(this).attr('href')).addClass('show');
}, function() {
$($(this).attr('href')).removeClass('show');
});
