I would like to implement a popup when I click on a part of a mathjax equation.
Here is what I have so far :
/* Popup container */
.popup {
position: relative;
display: inline-block;
cursor: pointer;
}
/* The actual popup (appears on top) */
.popup .popuptext {
visibility: hidden;
width: 160px;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 8px 0;
position: relative;
z-index: 1;
bottom: 125%;
left: 50%;
margin-left: -80px;
}
/* Popup arrow */
.popup .popuptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
/* Toggle this class when clicking on the popup container (hide and show the popup) */
.popup .show {
visibility: visible;
-webkit-animation: fadeIn 1s;
animation: fadeIn 1s
}
/* Add animation (fade in the popup) */
#-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
#keyframes fadeIn {
from {opacity: 0;}
to {opacity:1 ;}
}

I would like to make appear "this is the acceleration" when someone clicks on "a" but I don't find a way to associate my click function to a subsection of my equation by only using the \cssId{popup}{a}.

Driving me a bit insane, should be simple to figure out for all you vets.
Simply, the code works in browser preview if I just delete and then paste back in the Javascript file location line <script src="/JS/scripts.js"></script> (sometimes have to do this a few times) then all of a sudden it works in a browser preview but never in live view inside dreamweaver. Code stops working again if I save all files and reload.
The code seems to work fine if it's all included in the HTML file, but once I separate the script to an external file all hell breaks loose. Any insight/help would be much appreciated. Thanks in advance. Here is the code:
HTML:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="CSS/styles.css" rel="stylesheet" type="text/css">
<script src="JS/scripts.js"></script>
</head>
<body>
<h2>Image Modal</h2>
<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>
<img src="images/thumbnail4.jpg" id="myImg" alt="Testes123" style="width:100%;max-width:300px">
<!-- The Modal -->
<div id="myModal" class="modal">
<span class="close">×</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>
</body>
</html>
JAVASCRIPT:
// JavaScript Document
// Get the modal
var modal = document.getElementById("myModal");
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById("myImg");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
CSS:
body {font-family: Arial, Helvetica, sans-serif;}
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {opacity: 0.7;}
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
}
/* Modal Content (image) */
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}
/* Caption of Modal Image */
#caption {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}
/* Add Animation */
.modal-content, #caption {
-webkit-animation-name: zoom;
-webkit-animation-duration: 0.6s;
animation-name: zoom;
animation-duration: 0.6s;
}
#-webkit-keyframes zoom {
from {-webkit-transform:scale(0)}
to {-webkit-transform:scale(1)}
}
#keyframes zoom {
from {transform:scale(0)}
to {transform:scale(1)}
}
/* The Close Button */
.close {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
}
.close:hover,
.close:focus {
color: #bbb;
text-decoration: none;
cursor: pointer;
}
/* 100% Image Width on Smaller Screens */
#media only screen and (max-width: 700px){
.modal-content {
width: 100%;
}
}
Ok I guess I solved this on my own - if the scripts location line is at the beginning of the document it will fail, the scripts location line has to be at the end of the body after the modal code in order for it to function correctly.
How do I make a popup close when I click off it/click on a different one?
I've used EventListener to perform the function for the first popup, but when I do the same to a second popup the first popup stops working.
I've tried duplicating the JS code using different Function names and ID for the popups.
var popup = document.getElementById("myPopup");
function myFunction() {
popup.classList.toggle("show");
}
window.addEventListener('click', ({ target }) => {
if (!target.closest('.popup') && popup.classList.contains('show')) myFunction();
});
var popup = document.getElementById("myPopup2");
function myFunction2() {
popup.classList.toggle("show");
}
window.addEventListener('click', ({ target }) => {
if (!target.closest('.popup') && popup.classList.contains('show')) myFunction2();
});
/* Popup container - can be anything you want */
.popup {
position: relative;
display: inline-block;
cursor: pointer;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
/* The actual popup */
.popup .popuptext {
visibility: hidden;
width: 160px;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 8px 0;
position: absolute;
z-index: 1;
bottom: 125%;
left: 50%;
margin-left: -80px;
}
/* Popup arrow */
.popup .popuptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
/* Toggle this class - hide and show the popup */
.popup .show {
visibility: visible;
-webkit-animation: fadeIn 1s;
animation: fadeIn 1s;
}
/* Add animation (fade in the popup) */
#-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
#keyframes fadeIn {
from {opacity: 0;}
to {opacity:1 ;}
}
<body style="text-align:center">
<h2>Popup</h2>
<div class="popup" onclick="myFunction()">Click me to toggle the popup!
<span class="popuptext" id="myPopup">A Simple Popup!</span>
</div>
<h2>Popup2</h2>
<div class="popup" onclick="myFunction2()">Click me to toggle the popup!
<span class="popuptext" id="myPopup2">A Simple Popup again!</span>
</div>
</body>
Simply add another listener on the document, which will close any open modals.
Then add/modify one on your modal which will stop click events from bubbling up.
The end result is, click anywhere and if the click was over the modal, the modal will intercept and block, otherwise clicking anywhere else, then the document will receive the bubbled event and close the modal...
For good measure you can add a listener for the esc keydown event and close any open modals too
How do i customize css so the popup alert just like this but instead alert popup focus in a button.
i have use this kind of validation on text box
<div class="form-group">
<label class="control-label col-sm-3" for="judul_laporan">Judul Laporan </label>
<div class="col-sm-5">
<input type="email" class="form-control" id="judul_laporan" >
<span style="color: red" id="warnlaporan"></span>
</div>
</div>
<button type="button" id="save_laporan"></button>
JQuery
$("#save_laporan").click(function(){
var judul_laporan = $('input[name="judul_laporan"]');
if(judul_laporan.val() == ''){
judul_laporan.parent().parent().addClass('has-error');
$('#warnlaporan').text("Judul Laporan Belum Ada");
judul_laporan.focus();
result
}else{
judul_laporan.parent().parent().removeClass('has-error');
$('#warnlaporan').text("");
}
But i dont know how to make a popup alert likes the image ( and it should be button )
You can see the x3schools' documentation. It gives you a sample popup at the top of a div.
This code opens a popup:
// When the user clicks on <div>, open the popup
function myFunction() {
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
}
/* Popup container */
.popup {
position: relative;
display: inline-block;
cursor: pointer;
}
/* The actual popup (appears on top) */
.popup .popuptext {
visibility: hidden;
width: 160px;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 8px 0;
position: absolute;
z-index: 1;
bottom: 125%;
left: 50%;
margin-left: -80px;
}
/* Popup arrow */
.popup .popuptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
/* Toggle this class when clicking on the popup container (hide and show the popup) */
.popup .show {
visibility: visible;
-webkit-animation: fadeIn 1s;
animation: fadeIn 1s
}
/* Add animation (fade in the popup) */
#-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
#keyframes fadeIn {
from {opacity: 0;}
to {opacity:1 ;}
}
<div class="popup" onclick="myFunction()" style="left: 35px; top: 60px">Click me!
<span class="popuptext" id="myPopup">Popup text...</span>
</div>
You also can use microtip, it is a pretty library witch give you the opportunity to create simply popup. This is the only declaration: <button aria-label="Hey tooltip!" data-microtip-position="top-left" role="tooltip">. However, you have to download a package (just 1kb) with rpm in your server.
I am trying to make popups containing list of lines:
Support
Contact
Demo
In the 1st line, it should display Support. In the 2nd line, it should display Contact and in the 3rd line, it should display Demo.
I was able to create popups containing one line by following the w3schools link http://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_popup but I am not sure how to create popups having multiple lines.
The pictorial representation of what I am trying to get is shown here:
The code which I have used from the w3schools link is shown below:
<!DOCTYPE html> <html> <style> /* Popup container - can be anything you want */ .popup {
position: relative;
display: inline-block;
cursor: pointer;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none; }
/* The actual popup */ .popup .popuptext {
visibility: hidden;
width: 160px;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 8px 0;
position: absolute;
z-index: 1;
bottom: 125%;
left: 50%;
margin-left: -80px; }
/* Popup arrow */ .popup .popuptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent; }
/* Toggle this class - hide and show the popup */ .popup .show {
visibility: visible;
-webkit-animation: fadeIn 1s;
animation: fadeIn 1s; }
/* Add animation (fade in the popup) */ #-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;} }
#keyframes fadeIn {
from {opacity: 0;}
to {opacity:1 ;} } </style> <body style="text-align:center">
<h2>Popup</h2>
<div class="popup" onclick="myFunction()">Click me to toggle the popup! <span class="popuptext" id="myPopup">Support</span> </div>
<script> // When the user clicks on div, open the popup function myFunction() {
var popup = document.getElementById('myPopup');
popup.classList.toggle('show'); } </script>
</body> </html>
In place of A Simple Popup, I have written Support. At this moment, I am able to get only one line as shown here:
As a quick try do these steps to design what you want
1- open you mentioned link
2- change the html code to :
<div class="popup" onclick="myFunction()">Click me to toggle the popup!
<div class="popuptext" id="div">
<div><span id="myPopup">Support</span><br/></div>
<div><span id="myPopup1">Contact</span><br/></div>
<div><span id="myPopup2">Demo</span><br/></div>
</div>
</div>
3- change myFunction() code block to :
var popup = document.getElementById('div');
popup.classList.toggle('show');
4- Add this css class to style element in head
.popup .popuptext div{
text-align: center;
background:#ad4747;
border-radius: 6px;
width: 160px;
margin-top:2px;
}
5- At the end run and see the result
but as you know there are several ways to design popup menu by front-end tools ,
but my solution is a quick design hope give you some help.

I am creating a portfolio for the freecodecamp course. I want my portfolio page to have a slide out navigation menu, that slides out once you click on the menu button. I also want to have an image covering the body completely and when the menu slides into the page the picture would move with the body. I already have the slide out menu and the body moves along with the menu as it slides into the viewport, now I just need to figure out a way to add an image to the body that also responds to the slide out menu. Any help would be greatly appreciated!
This is my HTML and JS code that I have written so far.
<!DOCTYTPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" href="css/style.css">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body class="menu menu-open">
<header>
Menu
<nav class="menu-side">
This is a side menu
</nav>
</header>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
(function() {
var body = $('body');
$('.menu-toggle') .bind('click', function(){
body.toggleClass('menu-open');
return false;
});
})();
$(document).ready(function(){
$(".menu").css({"height":$(window).height() + "px"});
});
</script>
</body>
</html>
This is my CSS.
.menu{
overflow-x: hidden;
position: relative;
left:0;
}
.menu-open{
left:231px;
}
.menu-open .menu-side{
left: 0;
}
.menu-side,
.menu{
-webkit-transition: left 0.2s ease;
-moz-transition: left 0.2s ease;
transition: left 0.2s ease;
}
.menu-side{
background-color: #333;
border-right: 1px solid #000;
color: #fff;
position: fixed;
top: 0;
left:-231px;
width: 210px;
height: 100%;
padding: 10px;
}
.menu-toggle{
z-index: 1;
}
I think all you need to do is add a background image to the class you add to the body when the menu is open if I understand the question correctly.
.menu-open {
background-image: url('your-image.jpg');
}
You can simply add a div into a body (so you can have more flexibility to manipulate with the content):
<body>
<nav></nav>
<div>
<p>Menu</p>
</div>
</body>
Then use CSS to fill the window with the background and set style of your navigation:
html,
body {
margin: 0;
padding: 0;
}
html {
width: 100%;
height: 100vh; /* Relative to 100% of the height of the viewport (browser
automatically recognizes height of the window) */
box-sizing: border-box;
}
/* Adjust body size to the html */
body {
width: 100%;
height: 100%;
display: flex;
}
nav {
width: 200px;
height: 100%;
}
div {
width: 100%;
height: 100%;
/* Background resizes automatically when menu appears */
background-image: url('yourimage.jpg');
background-size: cover;
background-repeat: no-repeat;
}
And animate navigation with jQuery:
$("p").click(function() {
$("nav").animate({width:'toggle'}, 350);
});
