How to Replace li text but keep its child element? - javascript

I tried to do some functionalities like a Trello Card on editing card, that is to provide some options prompted to edit, move or copy card.
My sample code to do this is like this
$(document).ready(function() {
$('i').click(function() {
text = $(this).parentsUntil('ul').text();
$('body').addClass('bckg');
console.log(text);
// alert(text);
$(this).parentsUntil('li').append('<textarea class="textarea">' + text + '</textarea><ul class="opts"><li>Edit</li><li>change icon</li><li>delete</li></ul><br><br><br><button class="btn btn-success">Save</button>');
});
$('body').on('blur', 'textarea', function() {
textarea = $(this).val()
$(this).parentsUntil('ul').text(textarea);
$(this).remove();
// $(this).sibling('button').remove();
$('body').removeClass('bckg');
console.log(textarea);
})
})
.textarea {
position: absolute;
left: 0px;
z-index: 100;
float: left;
}
.opts {
position: absolute;
left: 150px;
top: 0px;
z-index: 100;
list-style-type: none;
/*background: #FFF;*/
}
.opts li {
padding: 15px;
background: rgba(0, 0, 0, .8);
}
.bckg {
background: rgba(0, 0, 0, .6);
}

<ul>
<li style="position: relative;">Option1 <i class="fa fa-pencil" aria-hidden="true"></i></li>
<li style="position: relative;">Option2 <i class="fa fa-pencil" aria-hidden="true"></i></li>
<li style="position: relative;">Option3 <i class="fa fa-pencil" aria-hidden="true"></i></li>
</ul>
The above script is working fine as I want to replace the <li> text with text from <textarea>, however, the problem is after jQuery Event .blur() I lost the edit icon <i> that I bind an event handler to it. Therefore I could not call it from the second time onward. How can I just change the text and keep edit icon with its event handler as it? Thanks.

This will help you with nested ul;
$(document).ready(function() {
})
var child;
$('body').on('click','i',function() {
$('body').addClass('bckg');
var text = $(this).closest("li").clone() //clone the element
.children() //select all the children
.remove() //remove all the children
.end() //again go back to selected element
.text();
child = $(this).closest("li").children();
$(this).closest("li").append('<textarea class="textarea">' + text + '</textarea><ul class="opts"><li>Edit</li><li>change icon</li><li>delete</li></ul><br><br><br><button class="btn btn-success">Save</button>');
});
$('body').on('blur', 'textarea', function() {
textarea = $(this).val()
var appendItem = textarea;
$(this).closest("li").text('').empty().append(appendItem).append(child);
$('body').removeClass('bckg');
})
.textarea {
position: absolute;
left: 0px;
z-index: 100;
float: left;
}
.opts {
position: absolute;
left: 150px;
top: 0px;
z-index: 100;
list-style-type: none;
/*background: #FFF;*/
}
.opts li {
padding: 15px;
background: rgba(0, 0, 0, .8);
}
.bckg {
background: rgba(0, 0, 0, .6);

$('body').on('blur', 'textarea', function() {
textarea = $(this).val()
var appendItem = textarea + '<i class="fa fa-pencil" aria-hidden="true"></i>'
$(this).parent().text('').empty().append(appendItem);

I wanted to toggle the sidebar, that means triggering a hide function when someone clicks on the hamburger menu indicated by the spann tag, as you can probably tell by the following:
<script>
function toggleSidebar(){
document.getElementsByClassName("sidebar");
}
</script>
So far it's not working yet as excepted, given that I'm an absolute beginner to CSS & Javascript. I would be super appreciative if someone could point out the things I might have done wrong.
In CodePen
I could fix the toggle functionality, hope this helps:
function toggleSidebar() {
var x = document.getElementsByClassName("sidebar")[0];
if(x.classList.contains('active')) {
x.classList.remove('active')
return;
}
x.classList.add('active')
}
if you check the sidebar div you'll see that class is being added and removed on toogle
You can use jQuery's toggle method. You need to have an onclick event on your .toggle-button with the name of your method (toggleSidebar), so it knows to call it when it's clicked.
You can also add an EventListener to your button instead of onclick.
.toggle-btn {
position: absolute;
left: 180px;
top: 70px;
}
.toggle-btn span {
display: block;
width: 30px;
height: 5px;

margin: 5px 0px;
}
.sidebar {
height: 100%;
width: 160px;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
padding-top: 70px;
}
.sidebar a {
padding: 6px 8px 6px 16px;
text-decoration: none;
font-size: 18px;

How make drop down menu on JavaScript?

please help me with the implementation of the drop-down menu from the list. Now, for practice, I make a site using the Bootstrap 4 library, and I encountered such a problem when clicking on any of the buttons, the list only appears from the first button, but it is necessary that when you click on any of the buttons a nested list will drop out. Thanks!
let getList = document.querySelectorAll('.sideBtn');
for(let a of getList) {
console.log(a);
a.addEventListener('click' , showList);
}
function showList () {
let getHide = document.querySelector('.hide');
console.log(getHide);
for (let i = 0; i < 1; i++) {
if(getHide.style.display == 'block') {
getHide.style.display = 'none';
} else {
getHide.style.display = 'block';
}
}
}
/*for(let b of getHide) {
console.log(b);
if(b.style.display == 'none') {
b.style.display = 'block';
} else {
b.style.display = 'none';
}
}*/

How to change font Awesome plus to minus using j Query

I have a plus font Awesome icon i want to change it into minus when user clicks on plus and vice versa
I am using it in my HTML table to expand some rows
$('i').click(function() {
$(this).find('i').toggleClass('fas fa-plus fas fa-minus');
});
.icon {
color: green;
cursor: pointer;
margin-right: 6px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<i class="fas fa-plus icon" data-toggle="collapse" data-target=".row1"></i>
You're almost there, but your selector is incorrect (you can just use $(this) inside of an event handler to reference the clicked element):
$('i').click(function() {
$(this).toggleClass('fa-plus fa-minus');
var color = ($(this).hasClass('fa-minus')) ? 'red' : 'green';
$(this).css('color', color);
});
.icon {
color: green;
cursor: pointer;
margin-right: 6px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<i class="fas fa-plus icon" data-toggle="collapse" data-target=".row1"></i>
No need to use find $this represent i, and toggle multi pal class to change class and shape like below.
$('i').click(function() {
$(this).toggleClass('fa-plus green fa-minus red');
});
.icon {
color: green;
cursor: pointer;
margin-right: 6px;
}
.green{
color: green;
}
.red{
color: red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<i class="fas fa-plus icon" data-toggle="collapse" data-target=".row1"></i>
You have to remove find() and it will be work.
$('i').click(function() {
$(this).toggleClass('fa-plus fa-minus');
$(this).hasClass('fa-minus')? $(this).css('color','red'): $(this).css('color','green');
});
.icon {
color: green;
cursor: pointer;
margin-right: 6px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<i class="fas fa-plus icon" data-toggle="collapse" data-target=".row1"></i>

Help much appreciated.
Try taking height: 100%; off of #side-menu h1. This will put your glyphicons inside the navigation area box instead of below it
#side-menu h1 {
height: auto;
}

How do i make my nav bar transparent when I scroll down and come back when I scroll up or when I hover my mouse over is?

How do i make my nav bar transparent when I scroll down and come back when I scroll up or when I hover my mouse over it? I tride to do this with jquery but i didn't really work.
Here's My HTML and CSS:
<DOCTYPE html>
<head>
<link rel="stylesheet" type="text/css" href="LunchWebsiteCSS.css">
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap-theme.min.css">
<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(window).scroll(
{
previousTop: 0
},
function () {
var currentTop = $(window).scrollTop();
if (currentTop < this.previousTop) {
//$(".sidebar em").text("Up"); /* optional for demo */
$(".nav").css({ opacity: 0.5 });
} else {
//$(".sidebar em").text("Down");
$(".nav").css({ opacity: 0 });
}
this.previousTop = currentTop;
});
});
</script>
<script src="js/jjquery.js"></script>
</head>
<body>
<div class="nav">
<ul>
<div class="btn-group">
<li>Browse
</li>
<li>Sign Up
</li>
<li>BHS Lunch</li>
<li>Log In
</li>
<li>Help
</li>
</div>
</ul>
</div>
</body>
.nav {
height: 35px;
font-size: 16px;
font-family: Tahoma, Geneva, sans-serif;
font-weight: bold;
width: 100%;
/*border: 1px solid black;*/
/*background-color: #AA3C39;*/
background-color: #AA3C39;
/*opacity: 0.7;*/
position: fixed;
}
This is how you can do it.
$(document).ready(function(){
$(window).scroll(function(){
if($(window).scrollTop()>100)
$(".nav").css({"background-color" : "rgba(0,0,0,.5)"});
else
$(".nav").css({"background-color" : "rgba(0,0,0,1)"});
});
});
Use CSS to see it back on hover
.nav:hover
{
background-color:rgba(0,0,0,1);
}
