so i have a menu and i add a font awesome icon on each parent menu.
and if they click the icon it will show slide down animation to show their child menu.
currently my code is like this
on css
li {
a {
border-bottom: solid thin $color-green;
#include font-size(1.2);
padding: 5px 0px;
}
.sub-menu {
display: none;
list-style: none;
padding: 0;
a {
padding: 5px 20px;
display: block;
}
}
&.menu-item-has-children {
a {
&::after {
content: '\f055';
font-family: FontAwesome;
font-weight: normal;
font-style: normal;
float: right;
}
&::before{
content: '\f056;';
font-family: FontAwesome;
font-weight: normal;
font-style: normal;
float: right;
}
}
}
}
on my php file( im using wp)
<div id="navbar-main-menu" class="collapse navbar-collapse">
<?php
if (has_nav_menu('primary_navigation')) :
wp_nav_menu(['theme_location' => 'primary_navigation', 'menu_class' => 'nav top-menu ']);
endif;
?>
</div>
<!--/.nav-collapse -->
i want to jquery active only on max resolution 767, so my script is like this.
but i dont know how to target the after and make specifict code so when i click 1 parent link it didnt trigger the other parent link to show their child menu.
var resizeTimer;
$(window).resize(function(e) {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(function() {
if ($(window).width() <= 767) {
$('.menu-item-has-children a::after').click(function() {
$('a').slideToggle();
});
} else {
}
});
});
this is my progress now
please help
Use this keyword instead of targeting a element.
var resizeTimer;
$(window).resize(function(e) {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(function() {
if ($(window).width() <= 767) {
$('.menu-item-has-children a').click(function() {
$(this).slideToggle();
});
} else {
}
});
});
On a separate note why are you using a timer to check the width. I am not sure if this is hindering with your code or not. If the above code doesn't work, please create a JSfiddle and share the link so that I can have a better look.
Update
Pseudo element doesn't work with jquery selector. Updated the code for the same. But this may not be complete solution OP is looking for.

I have This simple website that i need to make it change from light theme to dark theme, the light theme works fine, but the dark theme only changes its button properly because when i click in the button to change the "body" elements should change its class from "light-theme" to "dark-theme", instead it changes to "light-theme dark-theme"
here's HTML
`
<body class="light-theme">
<h1>Task List</h1>
<p id="msg">Current tasks:</p>
<ul>
<li class="list">Add visual styles</li>
<li class="list">add light and dark themes</li>
<li>Enable switching the theme</li>
</ul>
<div>
<button class="btn">Dark</button>
</div>
<script src="app.js"></script>
<noscript>You need to enable JavaScript to view the full site</noscript>
Heres CSS
:root {
--green: #00FF00;
--white: #FFFFFF;
--black: #000000;
}
.btn {
position: absolute;
top: 20px;
left: 250px;
height: 50px;
width: 50px;
border-radius: 50%;
border: none;
color: var(--btnFontColor);
background-color: var(--btnBg);
}
.btn:focus {
outline-style: none;
}
body {
background: var(--bg);
}
ul {
font-family: helvetica;
}
li {
list-style: circle;
}
.list {
list-style: square;
}
.light-theme {
--bg: var(--green);
--fontColor: var(--black);
--btnBg: var(--black);
--btnFontColor: var(--white);
}
.dark-theme{
--bg: var(--black);
--fontColor: var(--green);
--btnBg: var(--white);
--btnFontColor: var(--black);
}
and heres JavaScript
'use strict';
const switcher = document.querySelector('.btn');
switcher.addEventListener('click', function () {
document.body.classList.toggle('dark-theme')
var className = document.body.className;
if(className == "light-theme") {
this.textContent = "Dark";
} else {
this.textContent = "Light";
}
console.log('current class name: ' + className);
});
`
I tried to change some things in css but later found that the problem might be in the javascript, but my code is exactly as the code in my course is.
when i click in the button to change the "body" elements should change its class from "light-theme" to "dark-theme", instead it changes to "light-theme dark-theme"
That's indeed true - your JS code is only toggling the class "dark-theme" and does nothing with the "light-theme" class.
So a simple fix would be to toggle both classes:
switcher.addEventListener('click', function () {
document.body.classList.toggle('dark-theme')
document.body.classList.toggle('light-theme'); // add this line
var className = document.body.className;
if(className == "light-theme") {
this.textContent = "Dark";
} else {
this.textContent = "Light";
}
console.log('current class name: ' + className);
});
But you could simplify your code because you really don't need 2 classes here. If light theme is the default, just remove the light-theme class and all its CSS rules, and apply those to body instead. The .dark-theme rules will override these when the class is set, but not otherwise.
I am trying to show a description when hovering over an option in a select list, however, I am having trouble getting the code to recognize when hovering.
Relevant code:
Select chunk of form:
<select name="optionList" id="optionList" onclick="rankFeatures(false)" size="5"></select>
<select name="ranks" id="ranks" size="5"></select>
Manipulating selects (arrays defined earlier):
function rankFeatures(create) {
var $optionList = $("#optionList");
var $ranks = $("#ranks");
if(create == true) {
for(i=0; i<5; i++){
$optionList.append(features[i]);
};
}
else {
var index = $optionList.val();
$('#optionList option:selected').remove();
$ranks.append(features[index]);
};
}
This all works. It all falls apart when I try to deal with hovering over options:
$(document).ready(
function (event) {
$('select').hover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
alert('yeah!');
};
})
})
I found that code while searching through Stack Exchange, yet I am having no luck getting it to work. The alert occurs when I click on an option. If I don't move the mouse and close the alert by hitting enter, it goes away. If I close out with the mouse a second alert window pops up. Just moving the mouse around the select occasionally results in an alert box popping up.
I have tried targeting the options directly, but have had little success with that. How do I get the alert to pop up if I hover over an option?
You can use the mouseenter event.
And you do not have to use all this code to check if the element is an option.
Just use the .on() syntax to delegate to the select element.
$(document).ready(function(event) {
$('select').on('mouseenter','option',function(e) {
alert('yeah');
// this refers to the option so you can do this.value if you need..
});
});

That you want is to detect hover event on option element, not on select:
$(document).ready(
function (event) {
$('#optionList option').hover(function(e) {
console.log(e.target);
});
})
I have the same issue, but none of the solutions are working.
$("select").on('mouseenter','option',function(e) {
$("#show-me").show();
});
$("select").on('mouseleave','option',function(e) {
$("#show-me").hide();
});
$("option").mouseover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
alert('yeah!');
};
});
Here my jsfiddle https://jsfiddle.net/ajg99wsm/
I would recommend to go for a customized variant if you like to ease
capture hover events
change hover color
same behavior for "drop down" and "all items" view
plus you can have
resizeable list
individual switching between single selection and multiple selection mode
more individual css-ing
multiple lines for option items
Just have a look to the sample attached.

I have a code to make bs nav, but I don't understand how to make submenu always open without clicking menu name.
This is the code:
http://jsfiddle.net/6hrmodok/2/
and please answer this question with the new code.
To make the submenu always open in bootstrap navbar, you just need to add a class "open" like this <li class="dropdown open"> this will make your bootstrap's navbar submenu always open and it will toggle also.
.gw-nav-list>li.always-active>a,
.gw-nav-list>li.always-active>a:hover,
.gw-nav-list>li.always-active>a:focus,
.gw-nav-list>li.always-active>a:active {
background-color: #fff;
color: #2574A9;
font-weight: bold;
font-size: 13px;
}
.gw-nav-list>li.always-active:before {
display: inline-block;
content: "";
position: absolute;
left: 0px;
top: -1px;
bottom: 0;
z-index: 1;
border: 2px solid #2574A9;
border-width: 0 0 0 5px;
}
.always-active .gw-submenu,
.gw-nav-list>li.always-active .gw-submenu {
display:block;
}
And for JavaScript;
$('.gw-nav > li:not(.always-active) > a').click(function () {
....
Updated fiddle
you can open the submenu on page load with simple jquery code as below in your script file.
var pageload = function()
{
$(".gw-nav > li").each(function ()
{
var checkElement = $(this);
var ulDom = checkElement.find('.gw-submenu')[0];
if (ulDom != undefined) {
checkElement.addClass('active');
checkElement.find('ul').slideDown(300);
return;
}
});
}();

I have written a script to add a Pinterest button to most images on my site. The issue is that when someone has the Chrome Pin it extension enabled in their browser, the "pin it" button shows up twice for the user.
Is there anyway, in JavaScript, to check if the user has this extension enabled in their browser?
(function($) {
$(function() {
$('.container img').each(function() {
if ($(this).parent('a')) {
var $permalink = $(this).parent('a').attr('href');
}
else {
var $permalink = $(location).attr('href');
}
var $permalink = $(location).attr('href'),
$title = $('h1.product_name').text() || $('h2.header');
var $linkhtml = $('<a/>', {
'class':'pin-it-button pinme',
'html': '<img src="//assets.pinterest.com/images/pidgets/pinit_fg_en_rect_gray_20.png" />',
'count-layout': 'horizontal',
'style': 'cursor:pointer; position:absolute; bottom:30px; left:0; border:0 none; opacity: 0.4;',
'href': 'http://pinterest.com/pin/create/button/?url=' + $permalink + '&media=' + $(this).attr('src') + '&description=' + $title
});
if ($(this).parent('a')) {
$(this).addClass('pinme').parent('a').after($linkhtml);
}
else {
$(this).addClass('pinme').after($linkhtml);
}
$('.pinme').hover(
function() {
if ($(this).hasClass('pin-it-button')) {
console.log('hello');
$(this).css('opacity', '1');
}
else {
$(this).parent().siblings('.pin-it-button').css('opacity', '1');
}
}, function() {
if ($(this).hasClass('pin-it-button')) {
$(this).css('opacity', '0.4');
}
else {
$(this).parent().siblings('.pin-it-button').css('opacity', '0.4');
}
}
);
});
});
})(jQuery);

So a simple check would be:
var pin = document.querySelector('body > span[style*="8675309"][style*="rgb(189, 8, 28)"]')
Or you can check for the entire background base64 string which contains the P logo.
Old answer for the old PinIt extension:
Examining a page with Pin It extension installed we can see that it adds its own attribute to <body>:
<body data-pinterest-extension-installed="cr1.39.1">
It's easy to determine the presence of the attribute in js:
if (document.body.dataset.pinterestExtensionInstalled) {
console.log("Pin It extension detected!");
}
Note that the attribute is added after the page has been loaded so you can't check it right in DOMContentLoaded event handler; make a pause with setInterval or use MutationObserver:
Content script with "run_at": "document_end" or "document_idle" (the default mode):
var PinItInstalled = undefined;
new MutationObserver(function(mutations) {
PinItInstalled = document.body.dataset.pinterestExtensionInstalled;
this.disconnect();
}).observe(document.body, {
attributes: true,
attributeFilter: ["data-pinterest-extension-installed"]
});
Content script with "run_at": "document_start":
var PinItInstalled = undefined;
document.addEventListener("DOMContentLoaded", function() {
new MutationObserver(function(mutations) {
PinItInstalled = document.body.dataset.pinterestExtensionInstalled;
this.disconnect();
}).observe(document.body, {
attributes: true,
attributeFilter: ["data-pinterest-extension-installed"]
});
});
P.S. Don't forget to test what happens if the Pin It extension's option to show its button on hover is disabled.
While detecting the presence of the extension or pinit.js on the page may be worthwhile, the easier solution is to simply add the data-pin-no-hover attribute to your images. This will tell the extension to ignore the images.
<img src="whatevz" data-pin-no-hover="true" />
There really isn't any reason to care if it is installed or not if the data-pin attribute is set.
The other option is to not create your own hover buttons, but use pinit.js that creates the hover buttons for you. See the docs.
<script
type="text/javascript"
async defer
data-pin-hover="true"
src="//assets.pinterest.com/js/pinit.js"
></script>

Here my jsfiddle https://jsfiddle.net/ajg99wsm/
I would recommend to go for a customized variant if you like to ease
capture hover events
change hover color
same behavior for "drop down" and "all items" view
plus you can have
resizeable list
individual switching between single selection and multiple selection mode
more individual css-ing
multiple lines for option items
Just have a look to the sample attached.
