If one anchor is hidden, show another anchor?

How do you show one anchor, when another anchor is hidden? (I tried to do a custom context menu. And if you hover over the datasafety tab, the lock icon should close, to do this you have to do two different anchors with an open and a closed lock, that is why i wondered, how to show a anchor if another is hidden aka. display:none)
window.addEventListener("contextmenu", function(event) {
event.preventDefault();
var contextElement = document.getElementById("context-menu");
contextElement.style.top = event.offsetY + "px";
contextElement.style.left = event.offsetX + "px";
contextElement.classList.add("active");
});
window.addEventListener("click", function() {
this.document.getElementById("context-menu").classList.remove("active")
});

Thank you for your help

This problem is already Solved, i made a
onmouseenter=scriptStart();
and with
onmouseleave=scriptStop();
or in the Code
<div class="item" id="context-menu-home" onmouseleave="contextMenuHome_notActive()" onmouseenter="contextMenuHome_active()">
<i class="fa-solid fa-house"></i>Home
</div>
and it worked!

How to add javascript onclick event listener to container div?

Add onclick event listener to container div.
I tried the following, and as you can see, the event does not seem to be registered. How can I add the listener to this div?
The div id I want is "engineersContainer."
document.getElementById("engineersContainer").addEventListener("click", function(e) {
console.log("It was clicked");
alert("It was clicked");
});
.barContainer {
margin: 2px;
border: 2px solid black;
border-radius: 20px;
width: 200px;
//width:-moz-fit-content;
//width: fit-content;
padding: 5px;
overflow: hidden;
position: relative;
background: #34e8eb;
z-index: -1;
}
.containerHeader:before {
content:"";
background: skyblue;
position: absolute;
inset: 0;
z-index: -1;
height:45px
}
<div id="engineersContainer" class="barContainer">
<div id="engineerList" class="containerHeader" style="font-size:1.5em; text-align:center">Current Engineer </div>
<div> Engineer's Name</div>
<div id="clickText" style="padding-bottom: 10px; font-size:0.75em; text-align:center "> (Click to See All Permits) </div>
</div>

Remove the -1 z-index, otherwise it will be under the rest of the page
Add the event listener in the page load event
See second example for a workaround
window.addEventListener("load", function() {
document.getElementById("engineersContainer")
.addEventListener("click", function(e) {
console.log("It was clicked");
});
});
.barContainer {
margin: 2px;
border: 2px solid black;
border-radius: 20px;
width: 200px;
//width:-moz-fit-content;
//width: fit-content;
padding: 5px;
overflow: hidden;
position: relative;
background: #34e8eb;
/* z-index: -1 */
}
.containerHeader:before {
content: "";
background: skyblue;
position: absolute;
inset: 0;
z-index: -1;
height: 45px
}
.containerHeader {
font-size: 1.5em;
text-align: center
}
#clickText {
padding-bottom: 10px;
font-size: 0.75em;
text-align: center
}
<div id="engineersContainer" class="barContainer">
<div id="engineerList" class="containerHeader">Current Engineer </div>
<div> Engineer's Name</div>
<div id="clickText"> (Click to See All Permits) </div>
</div>
Otherwise add another div on top of it
window.addEventListener("load", function() {
document.getElementById("engineersContainerClick").addEventListener("click", function(e) {
console.log("It was clicked");
});
});
.barContainer {
margin: 2px;
border: 2px solid black;
border-radius: 20px;
width: 200px;
//width:-moz-fit-content;
//width: fit-content;
padding: 5px;
overflow: hidden;
position: relative;
background: #34e8eb;
z-index: -1
}
#engineersContainerClick {
margin: 2px;
border-radius: 20px;
width: 200px;
height:70px;
padding: 5px;
border:none;
overflow: hidden;
position: absolute;top:0;
background-color: transparent;
z-index:999;
}
.containerHeader:before {
content: "";
background: skyblue;
position: absolute;
inset: 0;
z-index: -1;
height: 45px
}
.containerHeader {
font-size: 1.5em;
text-align: center
}
#clickText {
padding-bottom: 10px;
font-size: 0.75em;
text-align: center
}
<div id="engineersContainer" class="barContainer">
<div id="engineerList" class="containerHeader">Current Engineer </div>
<div> Engineer's Name</div>
<div id="clickText"> (Click to See All Permits) </div>
</div>
<div id="engineersContainerClick" class="barContainer">

You need to remove the z-index: -1 in your CSS.
Any user clicks are not making contact with the element, but with the document above the element.
Working Example:
document.getElementById("engineersContainer").addEventListener("click", function(e) {
console.log("It was clicked");
alert("It was clicked");
});
.barContainer {
margin: 2px;
border: 2px solid black;
border-radius: 20px;
width: 200px;
/* width:-moz-fit-content; */
/* width: fit-content; */
padding: 5px;
overflow: hidden;
position: relative;
background: #34e8eb;
}
.containerHeader:before {
content:"";
background: skyblue;
position: absolute;
inset: 0;
z-index: -1;
height:45px
}
<div id="engineersContainer" class="barContainer">
<div id="engineerList" class="containerHeader" style="font-size:1.5em; text-align:center">Current Engineer </div>
<div> Engineer's Name</div>
<div id="clickText" style="padding-bottom: 10px; font-size:0.75em; text-align:center "> (Click to See All Permits) </div>
</div>

document.getElementById("engineersContainer").onclick=function(){
console.log("your event");
}
.barContainer {
margin: 2px;
border: 2px solid black;
border-radius: 20px;
width: 200px;
//width:-moz-fit-content;
//width: fit-content;
padding: 5px;
overflow: hidden;
position: relative;
background: #34e8eb;
}
.containerHeader:before {
content:"";
background: skyblue;
position: absolute;
inset: 0;
z-index: -1;
height:45px
}
<body>
<div id="engineersContainer" class="barContainer">
<div id="engineerList" class="containerHeader" style="font-size:1.5em; text-align:center">Current Engineer </div>
<div> Engineer's Name</div>
<div id="clickText" style="padding-bottom: 10px; font-size:0.75em; text-align:center "> (Click to See All Permits) </div>
</div>
</body>
ng-js -->
document.getElementById("engineersContainer").onclick=function(){
console.log("your event");
}
<div id="engineersContainer"> Here is the Engineers Container
</div>
I would use an anonymous function for this. You must call the script after your div has been created, as Javascript is read top to bottom and will not have a reference if it is run before the div has been placed.
Beware that if you have a listener on the container div, it will impact your ability to introduce any clickable options within the divs child elements such as buttons later on. Could this cause you problems in the future? If so rethink the design possibly to save you some trouble later. Also, the negative Z index needs to be removed as it is being drawn beneath the layer that Javascript detects the clicks. Sorry for the edits I'm new to StackO.

Changing display of elements in hover of another element does not work as it should

I want to change the display of the elements with the .slide-prev and .slide-next classes. As I'm using a slide plugin, it automatically creates the navigation elements outside the ul, so the only way the display change worked was with javascript. The problem is that it did not work as it should.
When I move the mouse over the div with the class .intro-noticias the elements appear, and when I leave they disappear, so far so good. The problem is when I hover over the elements .slide-prev and .slide-next, they are shaking, disappearing depending on where the arrow is and do not activate the hover.
It may be that I let something simple go by, but I really have not found it, if anyone knows what's causing it, I appreciate it.
Video demonstrating the problem
$(".intro-noticias").hover(function() {
$('.slide-prev,.slide-next').css("display", "block");
}, function() {
$('.slide-prev,.slide-next').css("display", "none");
});
.intro-noticias {
width: 100%;
height: 85vh;
margin-top: 70px;
}
.slide-prev {
z-index: 20;
position: absolute;
top: 70px;
left: 0;
text-indent: -9999px;
height: 40px;
width: 40px;
border: solid 1px #fff;
background: rgba(0,0,0,0.5);
display: none;
}
.slide-prev:after {
content:"icon";
width: 20px;
height: 20px;
position: absolute;
bottom: 9.5px;
left: 2px;
display: block;
background: url("img/icones/previous.png") left center no-repeat;
}
.slide-prev:hover {
background: red;
transition: all 0.2s ease-in;
}
.slide-next {
z-index: 20;
position: absolute;
top: 70px;
left: 40px;
text-indent: -9999px;
height: 40px;
width: 40px;
border: solid 1px #fff;
background: rgba(0,0,0,0.5);
display: none;
}
.slide-next:after {
content:"icon";
width: 20px;
height: 20px;
position: absolute;
bottom: 9.5px;
right: 2px;
display: block;
background: url("img/icones/next.png") right center no-repeat;
}
.slide-next:hover {
background: red;
transition: all 0.2s ease-in;
}
<ul>
<li>
<div class="intro-noticias">
<div>
<h2></h2>
</div>
</div>
</li>
</ul>
Previous
Next

You can wrap ul and anchors into the <div class="cont"> and bind events mouseenter and mouseleave to this div.
<div class="cont">
<ul>
<li>
<div class="intro-noticias">
<div>
<h2></h2>
</div>
</div>
</li>
</ul>
Previous
Next
</div>
$(".cont").mouseenter(function() {
$('.slide-prev,.slide-next').css("display", "block");
});
$(".cont").mouseleave(function() {
$('.slide-prev,.slide-next').css("display", "none");
});

<div> tags move up when other is selected

I have a jsfiddle:
http://jsfiddle.net/aritro33/y6wBy/
And when you hit the compose button on this jsfiddle, a post drops down revealing an assortment of colors above it. Notice how when you click on a color in the middle, or any color for the matter, all the colors to the left of that color move up slightly giving a weird effect. How would it be possible to prevent all the colors on the left of the div selected from moving up and in fact keeping them where they are.
Thanks!
HTML:
<div id="red" class = "color"></div>
<div id="orange" class = "color"></div>
<div id="yellow" class = "color"></div>
<div id="green" class = "color"></div>
<div id="turquoise" class = "color"></div>
<div id="blue" class = "color"></div>
<div id="purple" class = "color"></div>
<div id="gray" class = "color"></div>
CSS:
#red {
background-color: #2ac0a3;

background-color: #104c41;
}
#gray {
height: 16px;
width: 40px;
position: relative;
left: 645px;
bottom: 332px;
background-color: #0c3930;
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
.active{
height: 18px;
width: 45px;
z-index: 1;
border: 1px solid white;
}
JS:
$('.color').click(function(){ $('.active').removeClass('active'); $(this).addClass('active'); });

Your #active property changes the size of the colors:
.active{
height: 18px;
width: 45px;
z-index: 1;
border: 1px solid white;
}
If you change it to this:
.active{
height: 14px;
width: 45px;
z-index: 1;
border: 1px solid white;
}
the effect seems to go away.

It looks like the CSS for #gray has a few other properties, if you mimic the others, the slight movement seems to go away:
#gray {
position: relative;
left: 645px;
bottom: 332px;
background-color: #0c3930;}
Hopefully this helps!

For me, you may rewrite your CSS at all. To place every Element with position will let you run in to more problems at the end i think.

Hero Carousel Problems

The slider/carousel I'm trying to implent is this: http://www.paulwelsh.info/jquery-plugins/hero-carousel/
I know that I have to add HTML code for it, which I am unable to due to little experience with designing websites (started my course around a month ago). Can you help me with the HTML code I am supposed to add to get this to work? This is my HTML, CSS & Javascript. The HTML is what I THINK it should look like, which is obviously wrong.
HTML

You have to change the mark-up to:
<div class="hero">
<div class="hero-carousel">
<article>
<img src="slide-1.jpg" />
<div class="contents">text goes here</div>
</article>
<article>
<img src="slide-1.jpg" />
<div class="contents">text goes here</div>
</article>
</div>
</div>
Do not forget to add the jQuery mark-up like:
<script>
$(document).ready(function(){
$('.hero-carousel').heroCarousel({
easing: 'easeOutExpo',
css3pieFix: true
});
});
</script>
This should work for you.
EDIT - Try to use inspect element or view source to help you solve similar issues.
