so ive got this code
<div class="col-lg-12 video-meta">
<div class="container">
<span class="views"><i class="far fa-eye"></i>{{ Counter::show('post', $post->id) }}</span>
<span class="lnd">
<a class="like" href="#"><i class="far fa-thumbs-up"></i></a>
<a class="like" href="#"><i class="far fa-thumbs-down"></i></a>
</span>
and i target it with
$('.like').on('click', function(event) {
event.preventDefault();
var isLike = event.target.previousElementSibling == null;
console.log(isLike);
and it returns "true" in both cases, why?! is there a reason for this? ive been on it for 4 hours straight now and it worked ONCE , i did change nothing just took a break and then it didnt work after my break? i think this is some kind of bad joke. what am i missing here?
it should basically take the "like" class, and as the first a tag has no previousSiblingElement which is null, it should return true, but the second has an element with the same tag as a sibling and still returns true..
event.target is the <i> element, because that's the element on which the click really occured.
If you want the <a> (on which you did attach the event handler), you need to request event.currentTarget or even just this:
$('.like').on('click', function(event) {
event.preventDefault();
console.log(event.target); // <i>
var isLike = event.currentTarget.previousElementSibling == null;
console.log(isLike);
});

help me get the value from the button, I can not
my code:
<i class="fas fa-shopping-cart"></i> press
<script>
funk = (a) => {
console.log(a.value)
}
</script>
Set a value in HTML and retrieve it on click with getAttribute
<i class="fas fa-shopping-cart"></i> press
const funk = (a) => {
console.log(a.getAttribute("value"))
}
There's a few issues in your code:
The link will transfer the page, so you probably need to preventDefault
a elements don't have a value attribute. Use a data attribute to add custom metadata to an element
Use an unobtrusive event binding, not outdated onclick attributes
Here's a corrected version using plain JS:
document.querySelectorAll('.price-button').forEach(el => {
el.addEventListener('click', e => {
e.preventDefault(); // stop the page transfer
const button = e.target;
console.log(button.dataset.value);
});
});
<a href="#" data-value="123" class="price-button">
<i class="fas fa-shopping-cart"></i>
press
</a><br />
<a href="#" data-value="456" class="price-button">
<i class="fas fa-shopping-cart"></i>
press
</a>
And the same thing in jQuery, as you tagged that as well:
jQuery($ => {
$('.price-button').on('click', e => {
e.preventDefault(); // stop the page transfer
const $button = $(e.target);
console.log($button.data('value'));
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.1/jquery.min.js"></script>
<a href="#" data-value="123" class="price-button">
<i class="fas fa-shopping-cart"></i>
press
</a><br />
<a href="#" data-value="456" class="price-button">
<i class="fas fa-shopping-cart"></i>
press
</a>
Hi I am building a small slideshow of icons and also want to have data inside the icons like its speed and color. I've loaded jQuery from the top of my page.
<body>
<div class="main-container">
<div class="object-container">
<div class="icon-container">
<i class="fa fa-car" id="active"></i>
<i class="fa fa-bicycle" id="not-active"></i>
<i class="fa fa-plane" id="not-active"></i>
<i class="fa fa-ship" id="not-active"></i>
<i class="fa fa-fighter-jet" id="not-active"></i>
<i class="fa fa-space-shuttle" id="not-active"></i>
</div>
<div class="arrow-buttons">
</div>
</div>
</div>
</body>
Here is the jquery to press the right arrow button to change slide across the icons but it doesnt seem to be working?
$(document).ready(function(){
$('.right-arrow').on('click', function(){
let currentImg = $('#active');
let nextImg = currentImg.next();
if(currentImg.length){
currentImg.removeAttr('#active').css('z-inex', -10)
nextImg.attr('#active').css('z-index', 10);
}
});
});
First of all, I recommend using class instead of id. Even if you are going to use id, it is not recommended to use this way. The id value must be uniq. In your case, your ID's are not uniq. And also this is better to use like this ID selector.
id="notActive"
You can just try with each function to get current div. I tried with your code but did not work, with each yes.
$('.fa').each(function(){
if( $(this).hasClass('active') ){
currentImg = $(this);
}
})
And bonus : You can also use current div index value, then you dont have to use prev, next. You can increase or decrease index the value one by one. Just a suggestion.
You are using the id attribute incorrectly, as every id must be unique.
Also, setting the z-index on elements has no effect.
Finally, jQuery is not helping and can be eliminated.
Here's a more standard way to make something active/inactive, using a class named `active':
// control buttons
const right = document.querySelector('.right-arrow');
// handle right click
right.onclick = function() {
const activeImg = document.querySelector('i.active');
const nextImg = activeImg.nextElementSibling;
if (activeImg && nextImg) {
activeImg.classList.remove('active');
nextImg.classList.add('active');
}
};
i {
font-size: 32px;
z-index: -10; /* this has no effect */
}
.active {
z-index: 10;
background-color: yellow;
}

I have the following code which adds divs within a container (#subtask_container) via clicking a link (similar to Google Tasks):
HTML:
<p class="text-muted">
<i class="fas fa-tasks mr-2"></i>
Add subtasks
</p>
<div id="subtask_container"></div>
JS (this successfully adds unique inputs within the subtask container div along with a clickable x after each input)
var i = 1
$("#add_subtask").click(function () {
$("#subtask_container").append('<input name="subtask'+i+'" class="mt-1" id="subtask'+i+'" placeholder="Enter subtask"><i class="fas fa-times ml-1 text-muted"></i><br>');
i++;
});
What logic do I need to add to the x class to remove it's associated input?
I've tried
$('.fa-times').click(function(){
$(this).prev('input').remove();
});
but it doesn't seem to work...
Thanks!
You can simply wrap your subtask append in a div and simply use .parent() and .remove() function on that. No need to use <br>
Also, do not use .fa-times as primary click event handler as you might have other fa-times on the same page as well Which might cause issues later on. Add a custom class to your fa item (.subtask_remove_icon)
Live Demo:
var i = 1
$("#add_subtask").click(function() {
$("#subtask_container").append('<div><input name="subtask' + i + '" class="mt-1" id="subtask' + i + '" placeholder="Enter subtask"><i class="fas fa-times ml-1 text-muted subtask_remove_icon"></i></div>');
i++;
});
$(document).on('click', '.subtask_remove_icon', function() {
$(this).parent().remove(); //remove the input when X clicked
});

<script src="https://kit.fontawesome.com/a076d05399.js"></script>
<p class="text-muted">
<i class="fas fa-tasks mr-2"></i>
Add subtasks

<div id="subtask_container"></div>
The event handler gets attached to all elements that are on the page load. Since the icons are appended, the right way to do this would be the following:
var i = 1
$("#add_subtask").click(function () {
$("#subtask_container").append('<div><input name="subtask'+i+'" class="mt-1" id="subtask'+i+'" placeholder="Enter subtask"><i class="fas fa-times ml-1 text-muted removeIcon"></i><br></div>');
i++;
});
$(document).on('click', '.removeIcon', function(){
$(this).parent().remove();
});

<p class="text-muted">
<i class="fas fa-tasks mr-2"></i>
Add subtasks
</p>
<div id="subtask_container"></div>
I'm having trouble figuring out why my click event is not firing. I am trying to click on the trash can icon and have a function run that deletes the list element. After the click event, it fails to execute anything else in the script. It doesn't even console.log anything directly below. Below is the markup and my script.
HTML CODE
<div class="col-6">
<div class="js-list-item">
<h3 class="js-list-title"></h3>
<i class="fa fa-pencil" aria-hidden="true"></i>
<i class="fa fa-trash-o" aria-hidden="true"></i>
<p>Date: <span class="js-date"></span></p>
<p>Schedule: <span class="js-schedule"></span> at <span class="js-schedule-time">
</span></p>
</div>
</div>
javascript code
function handleDelete() {
$('.js-list-item').on('click', 'fa-trash-o', function(e) {
console.log('test');
e.preventDefault();
deleteShow(
$(e.currentTarget).closest('.js-list-item').attr('id')
);
});
}
The second parameter of the .on() function is a selector.
http://api.jquery.com/on/
Change:
$('.js-list-item').on('click', 'fa-trash-o', function(e) {
to:
$('.js-list-item').on('click', '.fa-trash-o', function(e) {
('click', 'fa-trash-o', function(e)
fa-trash-o is not a proper selector, use class or id
I'm wanting to use toolbar.js from http://paulkinzett.github.io/toolbar but even though I have the tool bar working the the handling of the events as documented I don't seem to be able to get identify which toolbar button/icon I clicked.
Below is the code snippit, which it pretty much lifted from the example site.
I'm no expert in JS, so if someone could enlighten me as to how to handle the toolbarItemClick event so that I can preform the correct action, that would be awesome.
Thanks
Lionel
<div id="user-options" class="toolbar-icons" style="display: none;">
<i class="icon-edit"></i>
<i class="icon-trash"></i>
</div>
<div class="tooltip-container normal">';
<section class="left">';
<div id="normal-button" class="settings-button"><img src="/3rdparty/paulkinzett-toolbar/documentation/img/icon-cog-small.png" /></div>';
</section>';
</div>
$('#normal-button').toolbar({content: '#user-options', position: 'top'});
$('#normal-button').on('toolbarItemClick',
function(event) {
console.log(event);
}
);
I was trying to figure out the same thing, eventually i deciphered the mechanism. A bit late to help you but maybe it will save someone else some time.
Firstly, I gave the button anchor tags IDs, though one could use data- attributes etc (note i am using img tags instead of the default glyph support)
<div id="user-toolbar-options">
<a id="menu-insert" href="#"><img src="add.png" width="18px" height="18px" /></a>
<a id="menu-remove" href="#"><img src="remove.png" width="18px" height="18px" /></a>
</div>
The key is to use a different function signature which isn't publicized in the documentation (function (event, buttonClicked){}, the 2nd parameter (buttonClicked) is the a element that was clicked on.
in the code below i also set targetBlock to the div that the button was in (as i have potentially dozens of articles and the button thats hows the toolbar appears on each) so i need to get the article in question to act on it.
$('#normal-button').on('toolbarItemClick',
function (event, buttonClicked) {
var targetBlock = $(event.target).parents('.article') // get article
var buttonClickedID = buttonClicked.id // get the id of the button click
switch (buttonClickedID) {
case 'menu-insert':
insertNewArticleBelow(targetBlock)
break;
case 'menu-remove':
removeArticle(targetBlock)
break;
}
}
$('#button').toolbar({
content: '#toolbar-options',
position: 'top',
style: 'primary',
event: 'click',
hideOnClick: true
});
$('#button').on('toolbarItemClick',
function( event,buttonClicked ) {
alert(buttonClicked.id);
}
);
