How to add and remove class with the condition of CSS display. For example, I have some Div that can be hidden and shown. I want that, if the div is hidden with the display:none;, then the class of the div is removed.
But if the div is shown with the display:block;, I want to add a class to the div.
Here is what I have been trying:
$(document).ready(function(){
if($('.bigPicture').css('display') == 'block')
{$('.bigPicture').find('div').addClass('easyzoom easyzoom--overlay');};
if($('.bigPicture').css('display') == 'none')
{$('.bigPicture').find('div').removeClass('easyzoom easyzoom--overlay');}
});
EXPLANATION
I have multiple slideshows in one pages. Not all of the slideshow is going to be shown in the page, one of them will only show if the link to that slideshow is clicked. It sames like auto hide and show function. If one slideshow is shown, then other slideshows are hidden.
Each slideshow has their own thumbnails to control them.
The problem is all of the slideshow has no ID and has the same class, while all the slideshow is run with the same script.
If the thumbnail in the second slideshow I click, the slideshow doesn't move. And I realize it slides only the first slideshow.
SO, the solution is I have to remove the class of the slideshow.
Try is visible:
$(document).ready(function(){
if($('.bigPicture').is(':visible')){
$('.bigPicture').find('div').addClass('easyzoom easyzoom--overlay');
} else {
$('.bigPicture').find('div').removeClass('easyzoom');
}
});
This is what you are trying to do?
If so, it's easy to convert it to jquery syntax instead.
It would be easier if you had provided a jsFiddle of your problem.
CSS
.bigPicture {
width: 50px;
height: 20px;
border-style: solid;
border-width: 2px;
}
.hidden {
display: none;
}
.easyzoom {
background-color: red;
}
HTML
<div class="bigPicture">
<div>One</div>
</div>
<div class="bigPicture hidden">
<div class="easyzoom easyzoom--overlay">Two</div>
</div>
<div class="bigPicture hidden">
<div class="easyzoom easyzoom--overlay">Three</div>
</div>
Javascript
document.addEventListener('load', function () {
Array.prototype.forEach.call(document.querySelectorAll('.bigPicture'), function (bigPicture) {
var div = bigPicture.querySelector('div:first-of-type');
if (div) {
if (window.getComputedStyle(bigPicture).display === 'none') {
div.classList.remove('easyzoom', 'easyzoom--overlay');
} else {
div.classList.add('easyzoom', 'easyzoom--overlay');
}
}
});
}, true);
On jsFiddle
I think your code is somewhat working. Here is a fiddle where I have shown and hidden on the click of the buttons.
Code Snippet:
$(document).on('click','#addBigPicture',function(){
$('.bigPicture').css('display','block');
if($('.bigPicture').css('display') == 'block')
{$('.bigPicture').find('div').addClass('easyzoom easyzoom--overlay');};
});
$(document).on('click','#hideBigPicture',function(){
$('.bigPicture').css('display','none');
if($('.bigPicture').css('display') == 'none')
{$('.bigPicture').find('div').removeClass('easyzoom easyzoom--overlay');}
});
The if loops are as desired by you. Hope it helps!!

I'm adding animation to show a hidden div when a checkbox is changed,
The first time it's clicked the div appears with no animation but it works both ways after the first time.
How can I make it work also on the first time?
Here is my div (also using bootstrap)
var postOptionsSourcesWrapper = $("#post-options-sources-wrapper");
var postOptionsExclusiveCheckbox = $("#post-exclusive-cb");
postOptionsExclusiveCheckbox.change(function() {
if ($(this).is(":checked")) {
postOptionsSourcesWrapper.slideUp(300, "easeOutCirc", function() {
postOptionsSourcesWrapper.addClass("hidden");
});
} else {
postOptionsSourcesWrapper.removeClass("hidden");
postOptionsSourcesWrapper.slideDown(300, "easeOutCirc");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="post-options-sources-wrapper" class="margin-b-5 hidden">
<label class="text-md thick-600">Original post references</label>
<div class="box-marker box-marker-white">
<div class="thick-600 color-gray text-sm text-uppercase">
Add one or multiple sources.
</div>
</div>
</div>
UPDATE: this issue is solved by adding display:none; to the div
When adding the bootstrap class .hidden to hide for some reason it's not adding the display:none; that is part of the .hidden class in bootstrap... not sure why, but adding the style display:none; or calling postOptionsSourcesWrapper.hide() solves this issue.
This code will achieve what you want to achieve.
You just have to replace your script with this one.
var postOptionsSourcesWrapper = $("#post-options-sources-wrapper");
var postOptionsExclusiveCheckbox = $("#post-exclusive-cb");
postOptionsSourcesWrapper.hide();
postOptionsExclusiveCheckbox.change(function() {
postOptionsSourcesWrapper.slideToggle(300,postOptionsSourcesWrapper.is(":checked"));
});
Things have gotten out of hand for me. What started off as the simplest solution has ballooned to the point where it is no longer manageable. I need to come up with a way to simplify a process.
Currently I have a map with pins denoting specific countries world-wide. As the mouse hovers over a pin, a hidden div appears. When you mouse over another one, the previous div disappears and a new one opens. I started with like 5 of these and it wasn't an issue but I keep getting requests for more and want to manage the script in a different way now.
$('#PH1').mouseenter(function () {
$('#BO2').hide();
$('#US2').hide();
$('#UK2').hide();
$('#CH2').hide();
$('#BZ2').hide();
$('#QC2').hide();
$('#OT2').hide();
$('#VA2').hide();
$('#RU2').hide();
$('#JT2').hide();
$('#HK2').hide();
$('#SH2').hide();
$('#BJ2').hide();
$('#XI2').hide();
$('#BE2').hide();
$('#AT2').hide();
$('#FR2').hide();
$('#MX2').hide();
$('#PH2').show();
});
$('#PH1').click(function (e) {
e.stopPropagation();
});
$('#mint').click(function () {
$('#PH2').hide();
});
In this instance div id #PH1 is the pin, when the mouse enters the div it hides all of the other div's #**2 and displays the one related to #PH1, which is #PH2
This list is repeated for each DIV. Every time I need to add a new DIV I need to make each existing list longer as well as create a new one. How can this process be made much simpler?
Thats not a right way to do this, you should use classes for this. But their is a wayaround for this all you need to is add a class add class ele1 to all #**1 and ele2 to all #**2:
then
$('.ele1').mouseenter(function () {
$(".ele2").hide();
var id = this.id;
var newId = id.substring(0,2)+"2";
$("#"+newId).show();
});
Make a loop:
var all= ['#BO2', '#US2', '#UK2', '#CH2', '#BZ2', '#QC2', '#OT2', '#VA2', '#RU2', '#JT2', '#HK2', '#SH2', '#BJ2', '#XI2' , '#BE2', '#AT2', '#FR2', '#MX2', '#PH2']
all.forEach(function (i){
$(i).hide();
});
Use a class selector on all of the DIVs you want to hide/show instead of an ID.
First, add a shared class to all DIVs so we target all of them by class.
HTML: class="hidden-divs"
jQuery: $('.hidden-divs').hide();
Then show the relevant DIV.
$('#PH2').show();
Using your first example, it would look like this:
$('#PH1').mouseenter(function () {
$('.hidden-divs').hide();
$('#PH2').show();
});
You can use jquery to hide multiple divs if you can select them. For example, suppose you have a common class ".map_divs" on all your divs, you could easily do:
$(".map_divs").hide();
On a side-note, you could solve all this on CSS, using :hover. For example:
.map_divs:hover {
display: block;
}
If you can edit the div's yourself (if it is not generated by a library) I would do it like this.
Add a common class to all your divs. Then on each div, add a data attribtue to the related id.
<div class="pin" id="PH1" data-rel="PH2"></div>
Then you can have a simple function like this:
$(".pin").mouseenter(function() {
var relatedId = $(this).data("rel");
$(".pin[id$='2']").hide(); // Hide all pins with id ending in 2
$("#" + relatedId).show() //show PH2
})
Using classes might be a better option here. You can then just attach the mouseenter event on document ready to all pins. This will work for an infinite number of pins too.
$('.pin').mouseenter(function () {
$('.popup').removeClass('show');
var id = this.id.split('_')[1];
$('#popup_' + id).addClass('show');
});
.pin {
width:30px;
height:30px;
margin-bottom:20px;
background-color:red;
}
.popup {
display:none;
width:100px;
height:100px;
margin-bottom:20px;
background-color:blue;
}
.popup.show {
display:block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="pin_1" class="pin"></div>
<div id="popup_1" class="popup"></div>
<div id="pin_2" class="pin"></div>
<div id="popup_2" class="popup"></div>
If your div element is ordered like below, you can get the same result using css only, which will increase speed and overall experience (especially on phones and tablets).
When "hover" the yellow squares, the popup will be visibible even when "hover" the popup.
.pin {
width:30px;
height:30px;
margin-bottom:20px;
background-color:red;
}
.popup {
display:none;
width:100px;
height:100px;
margin-bottom:20px;
background-color:blue;
}
.pin:hover + .popup {
display:block;
}
.pin.type2 {
background-color:yellow;
}
.pin.type2:hover .popup {
display: inline-block;
margin-top: 30px;
}
<div id="pin_1" class="pin"></div>
<div id="popup_1" class="popup"></div>
<div id="pin_2" class="pin"></div>
<div id="popup_2" class="popup"></div>
<div id="pin_3" class="pin type2"><div id="popup_3" class="popup"></div></div>
<div id="pin_4" class="pin type2"><div id="popup_4" class="popup"></div></div>
I have got 1 area, and on mouseenter I am fading in the following div:
$( "area.hasmore" ).mouseenter(function() {
$(this).next(".popup").stop().fadeIn();
});
Let's say the popup appears on the right hand side. What if the user leaves the area on the left hand side? Let's fade that popup out:
$( "area.hasmore, .popup" ).mouseleave(function() {
$(".popup").fadeOut();
});
Here comes my problem: users should be able to move the cursor into the fresh opened popup to the right and maybe even click a link in there. My problem is that it fades out due to the mouseleave event on the area. One problem might be the fact that the popup is no child. As a child of the area hovering the popup would still count as being 'inside' the area I guess. So I am kind of trying to find out how to keep the popup visible when mouseentering it and mouseleaving the area.
Here's the code:
<area class="hasmore" />
<div class="popup">...
Sry if I missed a question where this exact problem is being discussed.
jsfiddle here: fiddle
You could manage what is visible in the hover instead of mouseenter and mouseleave:
Something like this:
$('div').hover(function () {
console.log(this.className);
if (this.className === 'hasmore') {
$(this).next(".popup").stop().fadeIn();
} else if (this.className !== 'hasmore' && this.className !== 'popup') {
$(".popup").fadeOut();
}
});
Here is a fiddle demonstrating
html
<div class="hasmore">hover me</div>
<div class="popup">Popup 1</div>
<div class="evenmore">stuff</div>
<div class="popup">2nd popup. don't mind me</div>
Javascript
$( ".container" ).mouseenter(function() {
$(".popup").stop().fadeIn();
});
$( "div.container" ).mouseleave(function() {
$(".popup").fadeOut();
});
CSS (include this)
.container {
display: block;
line-height: 1em;
margin: 0;
padding: 0;
}
The trick is to create a div (.container) with display: block and enclosure .hasmore and .popup inside it!
this is going to be my first question so far cause i always do a research before using forums, but i dont get this to work.
I have an Image that works as a button for a toggle animation (button.png) and i want that image to change after clicking on it for another image (button2.png), and once you click the second image it changes again to the first image, i have:
<script type="text/javascript">
$(document).ready(function() {
// when click on the tag with id="btn"
$('#btn').click(function() {
// change the state of the "#idd"
$('#idd').toggle(800, function() {
// change the button text according to the state of the "#idd"
if ($('#idd').is(':visible')) {
$('#btn').attr('images/button2.png', this.href); // Show Less.. button
} else {
$('#btn').attr('images/button.png', this.href); //Learn More.. button
}
});
});
});
</script>
and my Html:
<div id="idd" style="display:none;">
- Here my hidden content -
</div>
<!-- Button -->
<img src="images/button.png" style="cursor: pointer;" id="btn">
What im doing wrong? Please Help :(
Check the syntax for .attr. It should be something like
$('#btn').attr('src', 'your image src');
Function Reference: http://api.jquery.com/attr/
To change the value of src you use 'attr' like this:
$('#btn').attr('src', 'images/button2.png');
Here is a DEMO
HTML
<div id="idd" class='display-none'>
- Here my hidden content -
</div>
<!-- Button -->
<img src="http://placekitten.com/40/40" id="btn">
CSS
.display-none {
display:none;
}
jQuery
var btn = $('#btn');
var idd = $('#idd');
btn.click(function() {
idd.toggle(800, function() {
// change the button text according to the state of the "#idd"
if (idd.hasClass('display-none')) {
btn.attr('src', 'http://placekitten.com/50/50');
idd.removeClass('display-none');
} else {
btn.attr('src', 'http://placekitten.com/40/40');
idd.addClass('display-none');
}
});
});
take one division e.g #play-pause-button and other in this i.e #play-pause. now put ur images in the src of inner division , on the click of outer divison source of innner division will change..
here is simillar example i'm working on. hope will help you.!
$('#play-pause-button').click(function () {
// $('#play-pause-button').play();
if ($("#media-video").get(0).paused) {
$("#media-video").get(0).play();
$("#play-pause").attr('src', "Image1 path");
}
else {
$("#media-video").get(0).pause();
$("#play-pause").attr('src', "Image2 path");
}
});
You should use css to associate image(s) on your "button" and a css class to determine which to show.
You can then use Jquery's ToggleClass() to add/remove the class. You can use the same class to show/hide your hidden content.
markup
<div id="idd">
- Here my hidden content -
</div>
<div id="btn">Click Me</div>
css
#idd.off {
display:none;
}
#btn {
border:1px solid #666;
width:100px; height:100px;
background:#fff url(images/button.png) no-repeat 0 0; // Show Less.. button
}
#btn.off {
background:#fff url(images/button2.png) no-repeat 0 0; //Learn More.. button
}
jquery
$('#btn').click(function(){
$('#idd').toggleClass('off');
$('#btn').toggleClass('off');
});
I have a number of parent divs (.parent_div), which each contain a child div (.hotqcontent) where I output data from my database using a loop.
The following is my current markup:
<div class="content">
<div class="parent_div">
<div class="hotqcontent">
content of first div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of second div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of third div goes here...
</div>
<hr>
</div>
<div class="parent_div">
<div class="hotqcontent">
content of fourth div goes here...
</div>
<hr>
</div>
</div>
What I would like to achieve is when a user hovers / mouseovers a parent div, the contents of the child div contained within should be revealed.
To achieve this I wrote the following jQuery script but it doesn't appear to be working. It's not even showing the alert!
<script>
$(document).ready(function() {
$(function() {
$('.parent_div').hover(function() {
alert("hello");
$('.hotqcontent').toggle();
});
});
});
</script>
How can I modify or replace my existing code to achieve the desired output?
If you want pure CSS than you can do it like this....
In the CSS below, on initialization/page load, I am hiding child element using display: none; and then on hover of the parent element, say having a class parent_div, I use display: block; to unhide the element.
.hotqcontent {
display: none;
/* I assume you'll need display: none; on initialization */
}
.parent_div:hover .hotqcontent {
/* This selector will apply styles to hotqcontent when parent_div will be hovered */
display: block;
/* Other styles goes here */
}
Demo
Try this
$(document).ready(function() {
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
});
});
Or
$(function() {
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
});
});
You can use css for this,
.parent_div:hover .hotqcontent {display:block;}
This can be done with pure css (I've added a couple of bits in just to make it a bit neater for the JSFIDDLE):
.parent_div {
height: 50px;
background-color:#ff0000;
margin-top: 10px;
}
.parent_div .hotqcontent {
display: none;
}
.parent_div:hover .hotqcontent {
display:block;
}
This will ensure that your site still functions in the same way if users have Javascript disabled.
Demonstration:
http://jsfiddle.net/jezzipin/LDchj/
With .hotqcontent you are selecting every element with this class. But you want to select only the .hotqcontent element underneath the parent.
$('.hotqcontent', this).toggle();
$(document).ready(function(){
$('.parent_div').on('mouseover',function(){
$(this).children('.hotqcontent').show();
}).on('mouseout',function(){
$(this).children('.hotqcontent').hide();
});;
});
JSFIDDLE
you don't need document.ready function inside document.ready..
try this
$(function() { //<--this is shorthand for document.ready
$('.parent_div').hover(function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
//or
$(this).children().toggle();
});
});
and yes your code will toggle all div with class hotqcontent..(which i think you don't need this) anyways if you want to toggle that particular div then use this reference to toggle that particular div
updated
you can use on delegated event for dynamically generated elements
$(function() { //<--this is shorthand for document.ready
$('.content').on('mouseenter','.parent_div',function() {
alert("hello");
$(this).find('.hotqcontent').toggle();
//or
$(this).children().toggle();
});
});
you can try this:
jQuery(document).ready(function() {
jQuery("div.hotqcontent").css('display','none');
jQuery("div.parent_div").each(function(){
jQuery(this).hover(function(){
jQuery(this).children("div.hotqcontent").show(200);
}, function(){
jQuery(this).children("div.hotqcontent").hide(200);
});
});
});
