I got an accordion code from W3Schools but I'd like to replace a class of an icon <i>.
How may I switchClass() of a element within this on this code?
Code from W3Schools:
var acc = document.getElementsByClassName("course-row");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].onclick = function(){
this.classList.toggle("active");
this.nextElementSibling.classList.toggle("unit-row-hide");
}
}
My HTML:
<div class="row-history">
<div class="row course-row active">
<div class="course-name col-md-4">
<i class="fa fa-caret-right" aria-hidden="true"></i>
Curso Teste 4
</div>
<div class="course-progress col-md-2">
<div class="course-progress-bar-wrapper col-md-8">
<div class="course-progress-bar"> </div>
</div>
<div class="course-progress-percent col-md-4">100%</div>
</div>
<div class="course-remaining col-md-2">Completo</div>
<div class="course-timestamp col-md-2">21 horas atrás</div>
<div class="course-remove col-md-2"><i class="fa fa-times" aria-hidden="true"></i></div>
</div> <!-- .course-row -->
<div class="unit-row">
<div class="row single-unit">
<div class="unit-name col-md-4">
<i class="fa fa-angle-double-right" aria-hidden="true"></i>
Curso Teste 4 - Unidade 3
</div>
<div class="unit-nbsp col-md-4"> </div>
<div class="unit-timestamp col-md-2">21 horas atrás</div>
<div class="unit-remove col-md-2"><i class="fa fa-times" aria-hidden="true"></i></div>
</div>
</div> <!-- .unit-row -->
</div>
I need to replace the class fa-caret-right from <i class="fa fa-caret-right" aria-hidden="true"></i> to fa-caret-down when the div is collapsed and back to fa-caret-right when it is not collapsed.
You already use the appropriate function: classList.toggle(). Just select the <i> element and apply the function on it for both classes:
var fa = this.getElementsByTagName("i")[0];
fa.classList.toggle("fa-caret-right");
fa.classList.toggle("fa-caret-down");
The first one removes the right arrow, the second one adds the down arrow. On the next click it is vice versa (toggled).

In the following example I am trying to update the value of #viewer_campaign3 with new data and move the older values to other HTML elements. But I think what happens is that I end up overwriting the old data.
$('#viewer_campaign1').html($('#viewer_campaign2'));
$('#viewer_campaign2').html($('#viewer_campaign3'));
$('#viewer_campaign3').html("new data");
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

</div>
</div>
</div>
</div>
Any help is appreciated
In your .html() on $('#viewer_campaign1') and $('#viewer_campaign2'), you are not actually assigning the .html() value of each of the corresponding elements as intended.
So change this
$('#viewer_campaign1').html($('#viewer_campaign2'));
$('#viewer_campaign2').html($('#viewer_campaign3'));
To this
$('#viewer_campaign1').html($('#viewer_campaign2').html());
$('#viewer_campaign2').html($('#viewer_campaign3').html());
This will assign the values as you're intending. There were minor edits I made in the full code below, but these changes were all you needed to update appropriately.
$('#viewer_campaign1').html($('#viewer_campaign2').html());
$('#viewer_campaign2').html($('#viewer_campaign3').html());
$('#viewer_campaign3').html("new data");

I tried design a Web Page.
I am using carousel.
The Left and Right options doesn't work, Instead all the images gets added on the Vertical Manner.
<h3 style="text-align:center;">Top Visiting Sites</h3>
<div class="row">
<div class="col-lg-1 col-md-1 col-sm-1 col-xs-1"></div>
<div class="col-lg-10 col-md-10 col-sm-10 col-xs-10">
<div class="carousel slide media-carousel" id="media">
<div class="carousel-inner">
<div class="row" id="Places">
</div>
</div>
</div>
<a data-slide="prev" href="#media" class="left carousel-control">‹</a>
<a data-slide="next" href="#media" class="right carousel-control">›</a>
</div>
</div>
This is what i have used on html.
And this is the Js I have used.
for (var i = 0; i < total.length; i++) {
var stars = '<i class="glyphicon glyphicon-star"></i>';
var obj = sort[i];
$('#Places').append(`
<div class="carousel-item active">
<div class="col-md-3" style="border-right:2px solid gray;">
<div class="panel panel-info">
<div class="panel-body">
<div style="background-image: url(/Images/${ obj.Name}.JPG)" class="TourismImage"></div>
<h4><span> ${ obj.Name}</span></h4>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
</div>
</div>
</div>
</div>
`); }
You are adding all of your elements inside of the div with the class="item active". You need to add them to the carousel-inner div, each in a separate div with only the "item" class.
Your end result should look like this :
<div class="carousel slide media-carousel" id="media">
<div class="carousel-inner">
<div class="carousel-item active">
<!-- html of your first item -->
</div>
<div class="carousel-item">
<!-- html of your second item -->
</div>
<div class="carousel-item">
<!-- html of your third item -->
</div>
<div class="carousel-item">
<!-- html of your fourth item -->
</div>
</div>
</div>
The content inside append function misses the ending quote. Please check that.
$('#Places').append('
<div class="carousel-item">
<div class="col-md-3" style="border-right:2px solid gray;">
<div class="panel panel-info">
<div class="panel-body">
<div style="background-image: url(/Images/${ obj.Name}.JPG)" class="TourismImage"></div>
<h4><span> ${ obj.Name}</span></h4>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
<i class="glyphicon glyphicon-star"></i>
</div>
</div>
</div>
</div>
');
Can you try and see whether the above with end quote works?
You should also have your carousal-inner class id as Places and remove the class=row div
<div class="carousel slide media-carousel" id="media">
<div class="carousel-inner" id="Places">
</div>
</div>
Also remove active class as it should be set only on the first item, which you can do separately.
I have a div object that should be clickable when it contains the class "clickable". In the Click function I remove the "clickable" class, but it still fires when clicking the object. Will it continue to fire even when I remove the class?
HTML:
<div class="item-wrap" data-id="218" data-index="4" data-filename="gthspill.jpg">
<div class="info-wrap">
<div class="vote-wrap">
<div class="circle clickable" title="Like" data-toggle="tooltip" data-placement="bottom">
<i aria-hidden="true" class="icon exist d-none fas fa-thumbs-up"></i>
<i aria-hidden="true" class="icon no-vote far fa-thumbs-up"></i>
</div>
<div class="existing-wrap d-none">
<div class="inner">
<span class="separator">/</span>
<span class="count">0</span>
</div>
</div>
</div>
<div class="caption-wrap">
<h2 class="caption">Close Up</h2>
</div>
</div>
</div>
jQuery:
$("div.vote-wrap > div.circle.clickable").click(function () {
let $circle = $(this);
$circle.removeClass("clickable");
}
because you didn't unbind the event in the click callback.
You just remove the class.
$("div.vote-wrap > div.circle.clickable").click(function() {
let $circle = $(this);
$circle.removeClass("clickable");
$(this).unbind('click');//unbind the click event
alert('clicked , and unbind now!');
})
div.vote-wrap > div.circle.clickable {
background:pink;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item-wrap" data-id="218" data-index="4" data-filename="gthspill.jpg">
<div class="info-wrap">

<i aria-hidden="true" class="icon exist d-none fas fa-thumbs-up"></i>

</div>
<div class="existing-wrap d-none">

</div>
</div>
</div>
<div class="caption-wrap">
<h2 class="caption">Close Up</h2>
</div>
</div>
</div>
and another way:
$("div.vote-wrap").on('click','div.circle.clickable',(function() {
let $circle = $(this);
$circle.removeClass("clickable");
alert('clicked');
}))
div.vote-wrap > div.circle.clickable {
background:pink;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item-wrap" data-id="218" data-index="4" data-filename="gthspill.jpg">
<div class="info-wrap">

</div>
</div>
</div>

</div>
</div>
Use delegate event on() and unbind the click event with unbind('click') for dynamically created element.
$("div.vote-wrap > div.circle.clickable").on('click',function () {
let $circle = $(this);
$circle.removeClass("clickable");
$circle.unbind('click');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item-wrap" data-id="218" data-index="4" data-filename="gthspill.jpg">
<div class="info-wrap">
<div class="vote-wrap">
<div class="circle clickable" title="Like" data-toggle="tooltip" data-placement="bottom">
<i aria-hidden="true" class="icon exist d-none fas fa-thumbs-up"></i>
<i aria-hidden="true" class="icon no-vote far fa-thumbs-up"></i>
</div>
<div class="existing-wrap d-none">
<div class="inner">
<span class="separator">/</span>
<span class="count">0</span>
</div>
</div>
</div>
<div class="caption-wrap">
<h2 class="caption">Close Up</h2>
</div>
</div>
</div>
The element event handler is attached to is determined when listener is attached, not when the event is emitted.
you could rewrite that code like this:
// element instance is captured once
var $elem = $("div.vote-wrap > div.circle.clickable")
$elem.click(function () {
let $circle = $(this)
$circle.removeClass("clickable")
})
For solution to your problem check the answers of this question: Event binding on dynamically created elements?
I have a bit long info submission form. I have an option that someone click "add another", there is a notification box display with text like "Success!" like that with close button. Please check this image.
Therefore I have three "add another" buttons and three success alerts. When someone click close, that alert message needs to be disappear.
The problem
I used javascript for that success box. It does these things.
Click "Add another" button, appears success box. Click close button on
success box, box disappears.
Here is my code.
document.querySelector(".add-box").addEventListener("click", function() {
document.querySelector(".add-box-wrap").style.display = "inline-block";
});
document.querySelector(".add-box1").addEventListener("click", function() {
document.querySelector(".add-box-wrap1").style.display = "inline-block";
});
document.querySelector(".add-box2").addEventListener("click", function() {
document.querySelector(".add-box-wrap2").style.display = "inline-block";
});
$(".claim-btn-close").click(function() {
$(".add-box-wrap").hide();
});
$(".claim-btn-close1").click(function() {
$(".add-box-wrap1").hide();
});
$(".claim-btn-close2").click(function() {
$(".add-box-wrap2").hide();
});
<!-- This goes end of html page -->
function hide(target) {
document.getElementsByClassName(target).style.display = 'none';
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!--Success form-->
<div class="add-box-wrap">
<div class="claim-btn-close" onclick="hide('.claim-btn-close')">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<!--Add another button -->
<div class="col-lg-10 col-md-10 col-sm-12 no-padding">
<a class="add-box">Add another<i class="fa fa-plus"></i></a>
</div>
See.. there is a major problem with code repeating. (I didn't repeat html codes, just post here one example) I would like to know the best practice to achieve things like this.
For displaying the notification box without repeating the code, one of the way is you could make use of data attributes. Change the data attribute for all the buttons and let the class .add-box be the same. like so:
<div class="add-box-wrap1" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<div class="add-box-wrap2" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<!--Add another button -->
<div class="col-lg-10 col-md-10 col-sm-12 no-padding">
<a class="add-box" data-target="1">Add another<i class="fa fa-plus"></i></a>
</div>
<!--Add another button -->
<div class="col-lg-10 col-md-10 col-sm-12 no-padding">
<a class="add-box" data-target="2">Add another<i class="fa fa-plus"></i></a>
</div>
And change your Jquery to just one function.
$(".add-box").click(function() {
$(".add-box-wrap" + $(this).data('target')).show(); //.add-box-wrap1 or .add-box-wrap2
});
Explanation of the above line: It just means we are getting the value of the "clicked" button's data-target value(which is 1 or 2) AND appending that value to the "add-box-wrap"(which will be add-box-wrap1 or add-box-wrap2) to search for that element to display it using .show().
Using show() or .css jquery functions is upto you. But I suggest not to mix both vanilla JS and JQuery codes(like in your question).
Closing
You can simply use closest or parent, like so:
$(".claim-btn-close").click(function(){
$(this).parent().hide();
});
$(".add-box").click(function() {
$(".add-box-wrap" + $(this).data('target')).show();
});
$(".claim-btn-close").click(function(){
$(this).parent().hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="add-box-wrap1" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<div class="add-box-wrap2" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<!--Add another button -->
<div class="col-lg-10 col-md-10 col-sm-12 no-padding">
<a class="add-box" data-target="1">Add another<i class="fa fa-plus"></i></a>
</div>
<!--Add another button -->
<div class="col-lg-10 col-md-10 col-sm-12 no-padding">
<a class="add-box" data-target="2">Add another<i class="fa fa-plus"></i></a>
</div>
Update on another question(3 column):
Using bootstrap, you can wrap the add-box-wrap divs within a .row and give each of it a class like col-*-4(class="col-xs-4 col-md-4 col-lg-4") assuming you have 3 success buttons(12/3 = 4). So the first part of your html would become
<div class="row">
<div class="add-box-wrap1 col-md-4 col-lg-4" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<div class="add-box-wrap2 col-md-4 col-lg-4" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
<div class="add-box-wrap3 col-md-4 col-lg-4" style="display: none;">
<div class="claim-btn-close">
<i class="fa fa-times" aria-hidden="true"></i>
</div>
Success!
</div>
</div>
You can use DOM relationship to target the desired element. Bind event handlers using a common class then use .closest() to traverse up desired element.
$(".claim-btn-close").click(function(){
$(this).closest(".add-box-wrap").hide();
});
If element are dynamically generate use Event Delegation approach.
$(staticParentElemet).on('click',".claim-btn-close",function(){
$(this).closest(".add-box-wrap").hide();
});
