hi everyone i cant find the solution for my question on google. i just want to hide the images using there icon-value
like in the below example i just want to hide the image which have icon-value="1" in the div which have .box class
<div class="box">
<div class="icon"><img src="xyz/smiley.png" icon-value="1" icon-index="0"></div>
<div class="icon"><img src="xyz/1.png" icon-value="2" icon-index="1"></div>
</div>
use an attribute selector.
.box img[icon-value="1"] {
display: none;
}
CSS solution:
.box img[icon-value="1"] {
display: none;
}
Demo
PS: Notice the value in quotes. I don't think CSS attribute selectors will work if the value is not specified in quotes
jQuery solution:
$(".box img[icon-value=1]").css("display", "none");
Demo
using css try following
.box .icon img[icon-value="1"] {
display: none;
}
or if you are using jquery you can try this also
$(".box img[icon-value=1]").hide();

Ok so I have a div that contains a canvas and a span which contains an image. I want it such that if the user hovers over or focuses on the div that the image inside of the span will appear. The image wil be invisible otherwise.
Long story short I want to have a canvas with a red 'X' on the corner that is only visible when the canvas is active
$('image-canvas').hover(function() {
$('delete-image').addClass('active');
}, function() {
$('delete-image').removeClass('active');
})
.delete-image {
position: absolute;
top: 0px;
right: 0px;
}
.delete-image>img {
width: 32px;
visibility: hidden;
}
.delete-image.active>img {
width: 32px;
visibility: visible;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="canvas-container" tabindex="1">
<canvas id="imageCanvas"></canvas>
<span class="delete-image">
<img src="file:///E:/Apps/Emoji-App/emojis/icons/if_erase_delete_remove_wipe_out_181387.png"/>
</span>
</div>
The hover event fires just fine but the image refuses to toggle visibility. Any help?
When you use a class within your selector, write it like this:
$('.myDiv')
When you use an ID within your selector, write it like this:
$('#myDiv')
For further informations, check out jQuery's learning center website.
Seems like you have misspelled or have not specified the jQuery selector type (class . or id #). Please try this:
$('#imageCanvas').hover(function () {
$('.delete-image').addClass('active');
}, function () {
$('.delete-image').removeClass('active');
})
See here .
$("#control").mouseover(function(){
$('#img').show();
});
$("#control").mouseout(function(){
$('#img').hide();
});
#img{
display:none;
}
#control{
margin-bottom:10px;
padding:5px;
background-color:#eee;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='control'>Show/Hide</div>
<img src='https://cdn.sstatic.net/Sites/stackoverflow/img/404.svg' id='img'>
The question is not well-phrased, so I ain't sure I totally understood what you wanted.
When you try to select by class, don't forget the dot '.'
$('image-canvas').hover(function () {
$('.delete-image').addClass('active');
}, function () {
$('.delete-image').removeClass('active');
})
When using functions 'addClass', 'removeClass', 'toggleClass', etc. - you don't use the '.' sign because it is a function that refers only to classes. On the other hand, when using jQuery selector $(' ') or vanilla querySelector(' '), you should declare what kind of attribute you are selecting by, those will be '#' for ID, '.' for Class, and if you want to select by anything else you can use $('*[anyattribute=anyvalue]'), in your clase it could be $('span[class=delete-image]').
Good luck
Thanks for taking a look at my question.
I'm trying to be able to hover over portfolio items but I need to loop through them using each() because I need some way of identifying each item.
I'm trying to hover over .recent-work-item to show .recent-work-item__overlay the .show-none class does display:none;
Neither the hover nor the on.("mouseenter", function(){}) is working.
Here is the HMTL:
<section class="recent-work-item" data-portfolio-id="rwi-<?php echo $i;?>">
<div class="recent-work-item__overlay show-none">
<h3 class="color-white bolder-font"><?php the_title(); ?></h3>
VIEW CASE
</div>
<div class="recent-work-img">
<img src="<?php echo get_template_directory_uri();?>/assets/img/work1.jpg" class="portrait">
</div>
Here is the jQuery:
$.each($('.recent-work-item'), function(){
var thisid = $(this).attr("data-portfolio-id");
console.log(thisid);
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseenter', function(){
$(thisid).find('.recent-work-item__overlay').removeClass('show-none');
});
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseleave',function(){
$(thisid).find('.recent-work-item__overlay').addClass('show-none');
});
});
This is not working, I can't get the hover to work and all I want to do is add or remove a class, can I not do this in each().
I've researched thoroughly in StackOverflow but can't find an answer. I would REALLY appreciate any help I can get on this.
I have test your code in my codepen, and the problem you should use $(this) than use $(thisid)
$.each($('.recent-work-item'), function(){
var thisid = $(this).attr("data-portfolio-id");
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseenter', function(){
$(this).find('.recent-work-item__overlay').removeClass('show-none');
});
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseleave',function(){
$(this).find('.recent-work-item__overlay').addClass('show-none');
});
});
Here look at my codepen
Here I have added an example that shows how you could use CSS to show/hide elements. It might not give you exact answer to your problem, but it will help you change your stylesheets as per your requirement.
Essentially, as per the discussion in comments, I don't think you need javascript to design the page the way you need it.
.container {
padding: 10px;
border: 1px solid gray;
}
.container > .hideOnHover {
display: block;
}
.container > .showOnHover {
display: none;
}
.container:hover > .hideOnHover {
display: none;
}
.container:hover > .showOnHover {
display: block;
}
<div class="container">
<div class="hideOnHover">
This text will be hidden on hover.
</div>
<div class="showOnHover">
This text will be shown on hover.
</div>
</div>
I have a problem with the width of a select2 dropdown in my ASP.NET page. When I try to view the page with the Chrome emulator of devices screen, the select2 is larger than the containing div, and on the right it goes out of the screen. I saw with code inspection that it adds automatically a style attribute style="width: 498px;" in the <span class="select2 select2-container select2-container--bootstrap select2-container--below"> element that I did not set anywhere. The only operation that I did is to set $("#ContentPlaceHolderContent_mySelect").select2(); in the document.ready function(). My select2 dropdown is contained in a block:
<div class="form-group">
<label class="control-label col-md-3">Select structure</label>
<div class="col-lg-5 col-md-9">
<select class="form-control" id="mySelect" runat="server"></select>
</div>
</div>
How can I remove that style="width" option?
Select2 adds class .select2. You can override what script does using css.
Here I'm set select2 to have 100% width, using !important. If I would not do that select2 would have 24px width.
You can further customize other classes that select2 generates using some principle.
$(document).ready(function(){
$("#mySelect").select2();
});
.select2 {
width:100%!important;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.js"></script>
<div class="form-group">
<label class="control-label col-md-3">Select structure</label>
<div class="col-lg-5 col-md-9">
<select class="form-control" id="mySelect" runat="server"></select>
</div>
</div>
This works for me:
$('select').select2({
width: '100%'
});
and add CSS:
.select2-selection { overflow: hidden; }
.select2-selection__rendered { white-space: normal; word-break: break-all; }
Add to CSS "!important" if you need.
Getting Overflow? Do it with JS also
Using CSS width:100% sometimes get scrolling issue if some elements have overflow property. I would recommend using js also.
Add below js
$('select').select2({
width: '100%'
});
Add below CSS
.select2-selection { overflow: hidden; }
.select2-selection__rendered { white-space: normal; word-break: break-all; }
/*Copied from already given :) */
if you are using bootstrap ,use the below style
.form-group > .select2-container {
width: 100% !important;
}
try use dropdownParent
$('#mySelect2').select2({
dropdownParent: $('#myModal')
});
https://select2.org/dropdown#dropdown-placement
You don't need to use !important, you just can override it with max-width like:
.select2{
max-width: 100%;
}
The <span> with the .select2 class is created by the Select2 plugin just after creation a new select2 on a given <select>.
To make this span.select2 element responsive, we may have some possibilities, such as:
Use a % width (either on the original before creating the select2 element, or in the select2 width configuration option).
Override via CSS (for example when we use #media() queries). Note that this may affect the plugin's functionality or display.
For the 2nd one, we can use the adjacent sibling combinator (+) with the !important on the width value to style our select2's <span>, since normally the select2's span is created and inserted right after our <select>.
An example below:
#media (max-width: 400px) {
select.my-x-select + span.select2 {
width: 200px !important;
}
}
Note: select and span element selectors aren't needed, #media as an example use case.
First of all add Select2 class .select2 in select tag and used these CSS
.select2-container{
width: 100% !important;
}
.control-label {
width: 100%;
}
How do I delete pseudo-elements with jquery.
I tried before:
$('.myclass a:after').hide();
and it's not working like that.
You can't modify the pseudo elements directly using scripts, but you can use some workarounds.
One of them is to use a class like
$('button').click(function() {
$('.myclass a').addClass('hide-after');
})
.myclass a:after {
content: '++'
}
.hide-after:after {
display: none
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="myclass">
<a>something</a>
</div>
<button>Test</button>
When I click on it changes background. It works fine. But what if I want to click on it again to restore the original background? I have this code:
jQuery(document).ready(function($) {
$(".select").on("click", function () {
$(this).css("background-image", "url(images/selected.png)");
});
});
Here is jsfiddle EXAMPLE
Basically when I click on the div it changes the background, which is fine. But I want to have ability to click on it again to restore the original background.
It will be an alternative solution for tick box, but just for demo purposes.
Thanks
JS
replace
$(this).css("background-image", "url(images/selected.png)");
with
$(this).toggleClass("active");
Style
#multiselect .active {
background-image: url('...');
}
Fiddle http://jsfiddle.net/09xgrhxo/4/
Instead of using .css() to change the background-image I would add a class in your CSS and use .toggleClass().
Also be aware that simply adding a class will not be specific enough because your css is using:
#multiselect .select
you're going to have to target the class you add as a child of #multiselect:
#multiselect .change
CSS
#multiselect .change{
background-image: url(http://t2.gstatic.com/images?q=tbn:ANd9GcSZ51HqKXkejWAFcSBrodHd5eUN2QaIJro0jhN1YpmljSdQ5dj2)
}
JS
$(".select").on("click", function () {
$(this).toggleClass("change");
});
FIDDLE
You could use data-* attribute.
$('.select').attr('data-img', $('.select').css('background-image'));
$(".select").on("click", function() {
$(this).css("background-image", ($(this).css('background-image') == $(this).data('img')) ? "url(http://t2.gstatic.com/images?q=tbn:ANd9GcSZ51HqKXkejWAFcSBrodHd5eUN2QaIJro0jhN1YpmljSdQ5dj2)" : $(this).data('img'));
});
#multiselect .select {
background: url(http://t0.gstatic.com/images?q=tbn:ANd9GcQF_ErOlc78eOGZaEWb-dwPkrv2uyAoKx0Pbn3-e0tAZoUDSQRCsA) center;
width: 250px;
height: 100px;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="multiselect">
<div class="select">Option1</div>
<div class="select">Option2</div>
<div class="select">Option3</div>
</div>
Instead of writing background-img url in javascrpt, I would suggest to create two classes having same properties but different background-img url which you want to toggle. so here we will be toggling class (ultimately background-img) in javascript.
