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.

Input with a copy button just like github clone view

I need to develop a view with similar tooltip which is on github.
I tried using the css but was not able to create the exact ui.
My CSS is as follow
[tooltip] {
display: inline;
position: relative;
}
[tooltip]:hover:after {
background: #333;
background: rgba(0, 0, 0, .8);
border-radius: 5px;
bottom: 26px;
color: #fff;
content: attr(tooltip);
left: 20%;
padding: 5px 15px;
position: absolute;
z-index: 99;
white-space: nowrap;
}
[tooltip]:hover:before {
border: solid;
border-color: #333 transparent;
border-width: 6px 6px 0 6px;
bottom: 20px;
content: "";
left: 50%;
position: absolute;
z-index: 99;
}
Please advise how can I get the same effect.

For what is worth if you consider bootstrap, similar, or a partial bootstrap installation or related classes, you can achieve this like this:
HTML
<div class="container">
<div class="col-xs-4 col-xs-push-4 martop50">
<div class="input-group">
<span class="input-group-addon">https://</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-addon"><i class="fa fa-clipboard" data-toggle="tooltip" data-placement="bottom" title="Copy to clipboard"></i></span>
</div>
<span class="download-btn"><button class="btn btn-sm" ><i class="fa fa-download"></i></button></span>
</div>
</div>
CSS
.martop50{
margin-top:50px;
}
.download-btn{
display:inline;
float: left;
margin: 0px 2px;
}
.btn-group-sm>.btn, .btn-sm {
padding: 7px 12px;
font-size: 12px;
line-height: 1.5;
border-radius: 3px;
}
.input-group {
position: relative;
display: table;
border-collapse: separate;
width: 88%;
float: left;
}
Tooltip JQUERY
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})
The rest of your work would be practically cosmetics and replacing the http:// with a dropdown. That should be fairly easy for you to do.
Here is the DEMO

Try removing , adjusting left:20% , also possibly padding: 5px 15px; at [tooltip]:hover:after

Here's a tooltip that opens downwards.
[tooltip] {
display: inline;
position: relative;
border-bottom: 1px dotted rgba(0,0,0,.21);
}
[tooltip]:hover {
border-bottom: 1px solid transparent;
}
[tooltip]:hover:after {
background: #333;
background: rgba(0, 0, 0, .8);
border-radius: 5px;
top: calc(100% + 3px);
color: #fff;
content: attr(tooltip);
left: 50%;
transform: translateX(-50%);
padding: 5px 15px;
position: absolute;
z-index: 99;
white-space: nowrap;
box-sizing: border-box;
}
[tooltip]:hover:before {
border: solid;
border-color: transparent transparent rgba(0,0,0,.8);
border-width: 6px;
bottom: -3px;
left: calc(50% - 3px);
content: "";
position: absolute;
z-index: 99;
}
<div tooltip="I am tooltip">
I am some content.
</div>
<hr>
Let's see a tooltip on an <span tooltip="Hey, I'm a tooltip, too!">inline element.</span>
However, the way to go here is to have tooltip arguments on the html element and build specific positioning rules for your alignment params (You probably want to have tooltip-position attribute set to top|bottom|left|right and have specific CSS for each case). For example:
[tooltip][tooltip-position="bottom"]:hover:after { /*code here*/ }
From the looks of it, considering the required coding effort and your apparent CSS knowledge, using a library might save you some time. Possible candidates:
Bootstrap Tooltip
jQuery tootip
tooltipster
qtip2
tipped
tooltipsy
These are only a few examples, I'm not endorsing any of them and there are plenty of others. You should research this yourself and decide based on your projects' needs.

Position div at bottom of containing div

I am having issues placing my dT(Date/Time) div at the bottom of it's containing div. I have tried setting bottom: 0px; to no avail. Below is the html and css code I am using.
HTML:
<div class='container'>
<aside>
<img id="user-pic" src="images/blank-user.jpg">
#User_Name
<div id="trend"><h6>TRENDING</h6></div>
</aside>
<section class="main">
</section>
</div>
CSS:
#dT{
width:inherit;
bottom: 0px;
border-top: gray;
background-color: gray;
font-size: small;
}
.container{
margin-top: 80px;
}
section{
margin: auto;
width: 400px;
clear: left;
top: 100px;
}
.tweet{
width: 450px;
height: 225px;
background-color: #FFFFFF;
border: 4px solid #F1433F;
border-top-left-radius: 20px;
border-bottom-right-radius: 20px;
margin-bottom: 15px;
padding: 25px 15px 0px 15px;
}
.tweetContent{
width: inherit;
height: inherit;
margin: 5px 5px 0 5px;
border-bottom: 1px solid #EEEEEE;
border-top: 1px solid #EEEEEE;
}
There is some JQuery elements within my code that I have not poseted because I do not believe it would have any effect on the positioning of a div.
It appears that the jquery aspect of the code might have something to do with it so here it is.
UPDATE: removed JQuery because it was not relevant.

Add position:relative to parent of your #dT element . Only if it is relative you can control the child elements using left , right , bottom and top.
Update:
And to the child elements for which you want to change position using left add position:absolute
P.S : Need to add relative for the div that contains #dT and absolute for #dT
#parentofdT
{
position:relative;
}
#dT
{
position:absolute
}

Easily pixed with position:absolute;: https://jsfiddle.net/1Lsnjou9/
Good luck.

You should add position: relative or position: absolute property to make the bottom: 0px work
#dT{
width:inherit;
bottom: 0px;
border-top: gray;
background-color: gray;
font-size: small;
position: relative;
}

use position property like position absolute or position relative so as to work with top, left,right,bottom properties

Preview Images from mysql database of particular product Id only

I've created a script in which every data fetched from mysql database has maximum 4 Image's name and path. Problem is to view those Images user must click on preview link which shows a <div id='previewdivofimage'> as per the product Id link clicked and blur rest background. That div
should fetch name and path of the images from mysql database and display in that div but when I click on preview link it just display the last added product images and not the particular id linked which was clicked because to fetch mysql data of that particular product I need to go back and call php functions via jquery or ajax. I am not able to understand how can I fetch the product id and its image's name & path of that particular product Id from that div now, because page should not reload again for doing this activity. Since I am not familiar with Ajax have no clue how does it work. This is JSFIDDLE

Please help me convert this script to a simple image slider

Can some please, PLEASE! help me with this problem. Okay so I have a code that at first I thought worked well but I forgot that when the default <img src="test-img-1.jpg" class="actual-img"> content is loaded the first of the three buttons below the image should take the active css state that I've specified for the active buttons to take. Now what I want is for this little code to behave like a normal slider by loading in the css hidden contents into the ".image-area" div and it works when I click on the buttons. Problems only surface when I am I trying to give the first loaded content an active state. One way I believe can fix this (I can't implement it) is to let the first immediate default content be this inline hidden div: (
<div id="image-area2">
<div class="img-area-wrapper">
<img src="test-img-2.jpg" class="actual-img">
</div>
</div>) while somehow letting the first button be set to active. I should also mention that I'm not the best with jquery. Please help me fix this someone!
Here is a fiddle to get a better understanding: http://jsfiddle.net/pyrot/84sU4/
If my way of going about this is totally absurd please let me know.
this is my code:
<script type="text/javascript">
$(document).ready(function() {
//loads default content
//$('#image-area').load($('.menu_top a:first-child').attr('href'));
$('.o-links').click(function() {
// href has to be the id of the hidden content element
var href = $(this).attr('href');
$('#image-area').fadeOut(1000, function() {
$(this).html($('#' + href).html()).fadeIn(1000);
});
return false;
});
});
$(function() {
$('.o-links').click(function(e) {
//e.preventDefault();
$('.o-links').not(this).removeClass('O_Nav_Current');
$(this).addClass('O_Nav_Current');
});
});
</script>
this is my html:
<section id="image-slider-container">
<div class="image-slider-inner">
<div id="image-area">
<div class="img-area-wrapper">
<!--currently this is the default I want to change-->
<img src="test-img-1.jpg" class="actual-img">
</div>
</div>
<div id="image-area2">
<div class="img-area-wrapper">
<!--I would like this to be the default content that when

Does this mean that you want to add a class to the first button?
$('.o-links').click(function(e) {
// ...
}).first().addClass('O_Nav_Current');
instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:
CSS:
.image-area {
width: 100%;
height: auto;
display: none;
}
.image-area:first-of-type {
display: block;
}
JavaScript:
var $slides = $('.image-area'),
$btns = $('a.o-links');
$btns.on('click', function (e) {
var i = $btns.removeClass('O_Nav_Current').index(this);
$(this).addClass('O_Nav_Current');
$slides.filter(':visible').fadeOut(1000, function () {
$slides.eq(i).fadeIn(1000);
});
e.preventDefault();
}).first().addClass('O_Nav_Current');
