hi i have a javascript script for when i click on a img class other images go from invisible to visible and i can keep switching between them.i have added display:none on the css for the images i want to show up. but nothing seems to be working
Javascript
<script>
$('img.home').click(function() {
$('img.video && img.news && img.games && img.music').hide();
});
</script>
HTML
<nav align="middle">
<ul>
<li>
<img src="images/video-1.png" class="video" style="width:100px;height:50px;">
</li>
<li>
<img src="images/news-1.png" class="news" style="width:100px;height:50px;">
</li>
<li>
<img src="images/logo-4.png" class="home" style="width:80px;height:80px;" onclick="$('.video' || '.news' || '.games' || 'music').toggle();" onmouseover="this.src='images/logo-4-hover.png';" onmouseout="this.src='images/logo-4.png';">
</li>
<li>
<img src="images/games-1.png" class="games" style="width:100px;height:50px;">
</li>
<li>
<img src="images/music-1.png" class="music" style="width:100px;height:50px;">
</li>
</ul>
</nav>
CSS
li {
display: inline;
margin-right: .75em;
list-style: none;
margin: 0;
padding: 0;
}
html,body {
height: 100%;
/* new */;
}
ul {
position: fixed;
bottom: 0;
width: 100%;
list-style: none;
margin: 0;
padding: 0;
border: 2px solid #ccc;
border-width: 3px 0;
}
img.video {
display: none;
}
img.news {
display: none;
}
img.games {
display: none;
}
img.music {
display: none;
}
You need to update your code to
$('img.home').click(function() {
$('img.video, img.news, img.games, img.music').hide();
});
Additionally, if you want to toggle on the images then in place of hide(), use toggle()
And also, as #Mark suggested, enclose your script within document ready block.
Try this, use commas instead of the && and try loading script with document ready.
<script>
$(document).ready(function(){
$('img.home').click(function() {
$('img.video , img.news , img.games , img.music').hide();
});
});
</script>
Apart from the selector syntax problem which was already explained in another answers, all your images are placed inside anchor tags. You should also attach a click event handler to these anchors in order to stop event bubbling
This should work for you:
$("li a").click(function(e) {
e.preventDefault();
e.stopPropagation();
})
$('img.home').click(function(event) {
$('img.video , img.news , img.games , img.music').hide();
// OR:
// $(this).closest('li').siblings().find('img').hide();
});
You should also remove onClick attribute from the 'img.home' element as it's unnecesary (and improperly written)

I want to add a CSS class to a nav menu item each time it's clicked (so i can then style that menu item so people know this is the page they are on). I know I need to loop through the .menu-item class and add / remove a new CSS class using a loop, but I can't seem to get it to play ball.
I'm guessing I need to make the .menu-item the 'this' object and use a boolean to add or remove the CSS class, dependent on whether the currentItem variable is set to true or false.
I can't seem to get this to play though and I'm not 100% sure I'm using the event listener in the correct way.
Any help would be awesome.

Here is a modified codepen for your problem: https://codepen.io/anon/pen/RjJEWe?editors=1010
The code simply add current-item class to the clicked anchor, so you can style it however you want in css. You can also see event.preventDefault() in the code to prevent anchor from following your link, as it will reload the page and js won't do anything. It depends on the stack that you are using. If you have server backed website, the current link will be handled by the server and html returned will already have the class set appropriately, if you have frontend js framework (Angular, VueJS, ReactJS), you must handle it appropriately.
Just for your example you can see the code below:
var navlinks = document.querySelectorAll('li.menu-item > a');
// Loop through all the links and add event listener
navlinks.forEach(function(item) {
item.addEventListener('click', function(event) {
event.preventDefault();
// Remove the class from all elements
navlinks.forEach(function(item) {
item.classList.remove('current-item');
})
// add the class to the current one
this.classList.add('current-item');
});
});
Guys I was trying to make a notification menu which dropdown on click event.I have make that with below code but I have a problem that I can't hide it back.I want to hide it by clicking on body and div itself.How can I do that?
My html part.
<li class="clicker" >
<a>Notification</a>
<div class="display_noti">
<ol>
<span>This is it :D</span><br>
<span>This is it :D</span><br>
<span>This is it :D</span><br>
</ol>
</div>
</li>
My css part
.display_noti
{
width: 400px;
height: fixed;
display:none;
background-color: black;
color: white;
position: absolute;
top: 40px;
z-index: 2;
padding: 5px;
}
My jquery part.
$('.clicker').on('click',function(){
if($('.display_noti').css("display","none")){
$('.display_noti').show();
}
});
I am trying with this jquery code too but when I keep this code show() function doesn't work.
$('body').on('click',function(){
$('.display_noti').css("display","none");
});
just make your js code as:
$('.clicker').on('click',function(){
$('.display_noti').toggle();
});
http://jsfiddle.net/jp42q7t8/5/
Update:
also, if you want you may consider change the cursor shape on the li element to show that it is clickable like this:
.clicker { cursor:pointer; }
Update2:
If you add this somehow you can make the <div class="display_noti"> disappear when you click on it i don't know why though but it fixes it:
$('.display_noti').on('click',function(){
$(this).css({'background':'black'}); //same background color of the inner div
});
// hide some divs when click on window
var actionwindowclick = function(e){
if (!$(".display_noti, .clicker").is(e.target) // if the target of the click isn't the container...
&& $(".display_noti , .clicker").has(e.target).length === 0) // ... nor a descendant of the container
{
$(".display_noti").hide();
}
}
$(window).on('click',function(e){
actionwindowclick (e);
});
$('.clicker').on('click',function(){
$(".display_noti").slideToggle();
});
Jsfiddle
$(document).click(function(e) {
$('.display_noti').hide();
});
$('.clicker').on('click', function(e) {
$('.display_noti').toggle();
e.stopPropagation();
});
$('.display_noti').click(function(e){
e.stopPropagation();
});
.display_noti {
width: 400px;
height: fixed;
display: none;
background-color: black;
color: white;
position: absolute;
top: 40px;
z-index: 2;
padding: 5px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="clicker"> <a>Notification</a>
<div class="display_noti">
<ol> <span>This is it :D</span>
<br> <span>This is it :D</span>
<br> <span>This is it :D</span>
<br>
</ol>
</div>

I am trying to do an overview page on my website so that when I hover over a div on the overview page different sections of that div show different images. Essentially a slideshow but the image changes depending on where the cursor is.
I have managed to find some code that does what I want but it uses an a href to pull in the images which means if you click it, it goes to the link of the image.
Currently I just have placeholder images in but when finished each one will have specific project images in. As each div will just be one project the whole div should go to one html link and not just a specific image link of the image the user is hovering over.
All I want is the user to click and it go to a html link and not an img link.
Here is the code I am using:
The coding savvy people out there will probably have a much better solution for what I would like to achieve, I am interested to see any better solutions.

if($rotators.children(imgclass).hasClass('active')) {
// already active icon -- do nothing
} else {

$rotators.children('span').removeClass('active');
$rotators.children(imgclass).addClass('active');

});
Any help would be greatly appreciated!
Thanks,

I think you could best use a data attribute for this instead (if I understand the intention correctly) :
var imglink = $(this).data('image');
<div class="multi">
<ul class="rotator-nav fifth clearfix">
<li>
<a data-image="/img/FoI.jpg" href="#" class="img1"></a>
</li>
<li>
<a data-image="/images/card.jpg" href="#" class="img2"></a>
</li>
<li>
<a data-image="/images/amareal.jpg" href="#" class="img3"></a>
</li>
<li>
<a data-image="/images/edeva.jpg" href="#" class="img4"></a>
</li>
<li>
<a data-image="/images/amacover2.gif" href="#" class="img5"></a>
</li>
</ul>
...
If you'd still like to see the image over the original div, a pseudo element could be used. Advantage there is that they are not actual DOM elements and will not register clicks :
Demo
Now it would be great if the data attribute could be directly used for the content of the pseudo element as well but that doesn't seem possible. And you can't target them with JavaScript so each image would have to be defined with nth-of-type() in the stylesheet additionally.
You don't need to use .parent().parent()
Just use the parent's class to find the item.
Your $(this).parent() * 3 is the $(".multi")
So your $rotators can't find .rotator-icons,
you need to use one more parent or use siblings
And I suggest do not use class if there are no need to do one thing to lots of items.
I'm unable to make the popups 'redItem', 'blueItem' and 'greenItem' below visible again after setting their display to 'none'. I'm using a CSS selector to get them visible again when the mouse hovers over a node higher up in the nested list to no avail.
Here's the code:
<ul class="popups" style="vertical-align: bottom; padding: 0px; margin: 0px;">
<li style="width: 165px"><a id="topmostBox" href="#">One_high-up_item</a>
<ul class="popups">
<li>First-lower-item
<ul class="popups">
<li name="redItem" >Red</li>
<li name="blueItem">Blue</li>
<li name="greenItem">Green</li>
</ul>
</li>
</ul>
</li>
</ul>
.popups:hover > li {
display: block;
}
.popups {
background-color: white;
font-family: sans-serif;
font-size: 13.5px;
list-style: none;
position: relative;
border: 1px solid lightgray;
border-width: .05em;
border-top-color: rgb(165,165,165);
line-height: 1.2em;
display: inline-table;
}
function setTopColorAndVis(theNestedPopupAnchor)
{
var theColorName = theNestedPopupAnchor.innerHTML;
var topMenuBox = document.getElementById('topmostBox');
topMenuBox.innerHTML = theColorName ;
theNestedPopupAnchor.parentNode.style.display = "none";
}
What happens is this:
1) I select the color 'Red' (the 1st list item)
2) my call to setTopColorAndVis(this) makes the popup disappear (because the user selected an item, the color "Red", and now the popup is not needed for now)
3) but when I later hover the mouse over the "First-lower-item" list item, the child li that has the ul containing 'redItem', 'greenItem', 'blueItem' does not appear.
So my experience here is that I'm successfully able to hide the list items named 'redItem', 'blueItem' and 'greenItem' -- but when I hover over the "First-lower-item", despite my CSS code:
.popups:hover > li {
display: block;
}
The 'redItem', 'greenItem' and 'blueItem' do NOT reappear.
What am I missing here?
The inline style overrides you style in your css code. you should use onmouseover event and onmouseout instead.
Try
<li name="redItem" >Red</li>
function show(elem){
elem.parentNode.style.display = "block";
}
function hide(elem){
elem.parentNode.style.display = "none";
}
You cannot :hover over an element with display:none as it has no size...
instead of working with display, you can work with visibility - which will leave an area to hover over.
like so:
theNestedPopupAnchor.parentNode.style.visibility = 'hidden'
.popups:hover > li {
visibility: visible;
}

HTML:
<div class="section-header section-header-on" id="section_header_289" style="left: 50px;">
<span class="collapse"></span>
<div class="section-name">
<span class="name">Testing Facebox suff</span></div>
<ul class="tools">
<li>
<a class="trash" href="#"></a>
</li>
<li>
</li>
</ul>
<div class="clear"></div>
</div>
js:
$j = jQuery.noConflict();
$j(".section-header").hover(function(){
$j(this).find("ul").show();
});
So, I need this to be relative, because there are multiple "section-header"s and the ID is generally unknown / generated by the app. But, basically, I want to be able to hover over the section-header, and then have ul.tools change from display: none; to display: block. So I figured .show() could do that. but.. I guess my selector is wrong. =\
Your css specifies:
.section-header ul.tools,
.section-content li.content ul.tools {
visibility: hidden;
position: absolute;
top: 0;
left: -40px;
z-index: 1002;
cursor: default;
width: 40px;
height: 35px;
list-style: none;
}
Most notably visibility: hidden; which is not affected by the show()/hide() functions. So you need to change the css visibility property so your list will show-up.
Change:
$j(this).find("ul").show();
To:
$j(this).find("ul").css({visibility: 'visible'});
Or set the CSS to display: none; rather than use the visibility property.
show() documentation: http://api.jquery.com/show/
Demo
just needed a little coercion ;)
$j = jQuery.noConflict();
$j(".section-header").hover(function(){
$j(this).find(".tools").css({visibility:"visible"});
},function(){
$j(this).find(".tools").css({visibility:"hidden"});
});
Just needed a little css.
.tools {
display: none;
}
div.section-header:hover ul {
display: block;
}
