Show/Hide Multiple Divs Javascript - html

Looking for a good JavaScript to help me hide/show multiple divs with a button click not an a href click so I can use it in blogger.
I've been looking for an answer for a while now and have been unable to find a good one that uses JavaScript and/or CSS. I am a bit of a novice so bear with me.
Following is my code that works but I would like to simplify it and make it work so that it will close the div when I click the appropriate button again.
css
<head>
<style>
#myDIV1 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV2 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV3 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV4 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
</style>
</head>
I know there is an easier way but this is the only way that I can find that works for what I want it to do for the most part
html
<body>
<p>Click button to see div.</p>
<button onclick="myFunction1()">One</button>
<button onclick="myFunction2()">Two</button>
<button onclick="myFunction3()">Three</button>
<button onclick="myFunction4()">Four</button>
<div id="myDIV1">
This is the div1 element.
</div>
<div id="myDIV2">
This is the div2 element.
</div>
<div id="myDIV3">
This is the div3 element.
</div>
<div id="myDIV4">
This is the div4 element.
</div>
Javascript
<script>
function myFunction1() {
document.getElementById("myDIV1").style.display = "block";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction2() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "block";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction3() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "block";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction4() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "block";
}
</script>
Any help would be appreciated thanks in advance.

I would suggest to separate your code first - it would be then more clean and reusable - like myStyle.css, myScript.js, index.html
Add the css and js file in the html file like -
<link rel="stylesheet" type="text/css" href="myStyle.css">
<script type="text/javascript" src="myScript.js"></script>
src -> indicates the source path of the file. Here I assume that all our css, js, 'html' file in same place.
var divs = ["Div1", "Div2", "Div3", "Div4"];
var visibleDivId = null;
function divVisibility(divId) {
if(visibleDivId === divId) {
visibleDivId = null;
} else {
visibleDivId = divId;
}
hideNonVisibleDivs();
}
function hideNonVisibleDivs() {
var i, divId, div;
for(i = 0; i < divs.length; i++) {
divId = divs[i];
div = document.getElementById(divId);
if(visibleDivId === divId) {
div.style.display = "block";
} else {
div.style.display = "none";
}
}
}
.buttons a {
font-size: 16px;
}
.buttons a:hover {
cursor:pointer;
font-size: 16px;
}
<div class="main_div">
<div class="buttons">
Div1 |
Div2 |
Div3 |
Div4
</div>
<div class="inner_div">
<div id="Div1">I'm Div One</div>
<div id="Div2" style="display: none;">I'm Div Two</div>
<div id="Div3" style="display: none;">I'm Div Three</div>
<div id="Div4" style="display: none;">I'm Div Four</div>
</div>
</div>

if you want to hide/show all divs simultaneously than you have to give all divs same class for ex: .toggle and than you can do this:
function myFunction1(){
$(".toggle").slideToggle();
}
if you want to hide/show one div at a time than you can do this with id :
function myFunction1(){
$("#myDIV1").slideToggle();
}
with different buttons :
function myFunction1(id){
$("#"+id).slideToggle();
}
pass id here :
<button onclick="myFunction1('myDIV1')">One</button>
<button onclick="myFunction1('myDIV2')">Two</button>
<button onclick="myFunction1('myDIV3')">Three</button>
<button onclick="myFunction1('myDIV4')">Four</button>

I found the answer to what I wanted with the .toggle function thanks for the help. The answer I found here: radomsnippets.com

We can easily add an unlimited amount of buttons using reusable code.
here is a full example! Enjoy

Div showing on clicking button twice in the initial state

In the very initial state, I need to click on Read More button TWICE to have the content below show. Weird - how do i fix this problem? I only want to click on Read More button once to show the content underneath it.
function myFunction() {
var x = document.getElementById("myDIV");
var btnText = document.getElementById("myBtn");
if (x.style.display === "none") {
x.style.display = "block";
btnText.innerHTML = "Read less";
} else {
x.style.display = "none";
btnText.innerHTML = "Read More";
}
}
#myDIV {
display: none;
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top: 20px;
}
<p>Click the "Try it" button to toggle between hiding and showing the DIV element:</p>
<div id="myDIV">
This is my DIV element.
</div>
<button onclick="myFunction()" id="myBtn">Read More</button>
<p><b>Note:</b> The element will not take up any space when the display property set to "none".</p>
You should include a check if myDiv's display style is empty.
function myFunction() {
var x = document.getElementById("myDIV");
var btnText = document.getElementById("myBtn");
if (x.style.display === "none" || x.style.display === "") { // notice this line
x.style.display = "block";
btnText.innerHTML = "Read less";
} else {
x.style.display = "none";
btnText.innerHTML = "Read More";
}
}
#myDIV {
display: none;
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top: 20px;
}
<p>
Click the "Try it" button to toggle between hiding and showing the DIV element:
</p>
<div id="myDIV">
This is my DIV element.
</div>
<button onclick="myFunction()" id="myBtn">Read More</button>
<p>
<b>Note:</b> The element will not take up any space when the display property set to "none".
</p>
The reason it's working on two clicks is that the DOM is ready but the script does not knows that the div's style is display: none.
There are two ways you can fix this:
Using window.getComputedStyle()
The Window.getComputedStyle() method returns an object containing the values of all CSS properties of an element, after applying active stylesheets and resolving any basic computation those values may contain.
This way it will ensure that content will show in one click.
Demo:
function myFunction() {
var x = document.getElementById("myDIV");
var displayDiv = window.getComputedStyle(x).display; //this function
var btnText = document.getElementById("myBtn");
if (displayDiv === "none") {
x.style.display = "block";
btnText.innerHTML = "Read less";
} else {
x.style.display = "none";
btnText.innerHTML = "Read More";
}
}
#myDIV {
display: none;
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top: 20px;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
</style>
</head>
<body>
<p>Click the "Try it" button to toggle between hiding and showing the DIV element:</p>
<div id="myDIV">
This is my DIV element.
</div>
<button onclick="myFunction()" id="myBtn">Read More</button>
<p><b>Note:</b> The element will not take up any space when the display property set to "none".</p>
</body>
</html>
Using Inline styling on the div
You could simply set the display to inline style as display:none.
This way it will ensure that content will show in one click.
Demo:
function myFunction() {
var x = document.getElementById("myDIV");
var btnText = document.getElementById("myBtn");
if (x.style.display === "none") {
x.style.display = "block";
btnText.innerHTML = "Read less";
} else {
x.style.display = "none";
btnText.innerHTML = "Read More";
}
}
#myDIV {
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top: 20px;
}
<!DOCTYPE html>

How can I make an accordion panel clickable, not just text

Sorry in advance if this is a stupid question but I've been trying a load of different things and nothing is quiet right.
I'm also relatively new to all of this and working off someone else' code.
I'm trying to make the whole panel clickable and not just the text for an accordion.
This is the code.
<div uib-accordion-group is-open="topic6.open">
<uib-accordion-heading>
<strong>
<span id="help" style="font-size:16px;text-decoration:none;cursor:pointer;)" translate="help">
<i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-up': topic6.open, 'glyphicon-chevron-down': !topic6.open}" style="font-size:21px;"></i>
</span>
</strong>
</uib-accordion-heading>
<span translate="help_aboutmessage1"></span>
<br>
</div>
And this is what it looks like. As you can see all that is clickable at the moment is the "help" text.
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.accordion {
background-color: #eee;
color: #444;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
transition: 0.4s;
}
.active, .accordion:hover {
background-color: #ccc;
}
.panel {
padding: 0 18px;
display: none;
background-color: white;
overflow: hidden;
}
</style>
</head>
<body>
<h2>Accordion</h2>
<button class="accordion">Section 1</button>
<div class="panel">
<p>Panel #1</p>
</div>
<button class="accordion">Section 2</button>
<div class="panel">
<p>Panel #2.</p>
</div>
<button class="accordion">Section 3</button>
<div class="panel">
<p>Panel #3</p>
</div>
<script>
var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].addEventListener("click", function() {
this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.display === "block") {
panel.style.display = "none";
} else {
panel.style.display = "block";
}
});
}
</script>
</body>

by the way, i just copied this code from W3schools, so dont give me any credit

w3 schools modal tutorial not working [duplicate]

This question already has answers here:
Why does jQuery or a DOM method such as getElementById not find the element?
(6 answers)
Closed 6 years ago.
Hi im following the tutorial on w3 schools on modals
http://www.w3schools.com/howto/howto_css_modals.asp
but i cant seem to get mine to open at all. is there anything in my code that is going wrong or am i missing something.
or is there any different ways that you would recommend i do this?
<?php
session_start();
include 'loginlogoutregister.php';
//connecting to database
$link = mysqli_connect("localhost","root","","authentication");
if(isset($_POST['Login_Btn'])){

<p>Some text in the Modal..</p>
</div>
</div>
</body>
</html>
#PopUpLR{
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
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(0,0,0,0.4); /* Black w/ opacity */
}
.PopUpLRContent{
background-color: #fefefe;
margin: 15% auto; /* 15% from the top and centered */
padding: 20px;
border: 1px solid #888;
width: 80%; /* Could be more or less, depending on screen size */
}
.closeLR {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.closeLR:hover,
.closeLR:focus {
color: black;
text-decoration: none;
cursor: pointer;
}
moving the script to the bottom of the body tag solved this issue
Move your script <script>
var modal = document.getElementById('PopUpLR');
var btn = document.getElementById("myBtn");
var span = document.getElementsByClassName("closeLR")[0];
btn.onclick = function() {
modal.style.display = "block";
}
span.onclick = function() {
modal.style.display = "none";
}
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
under your HTML so the button knows what its sending to!

Hover header+Sub-header that adapts when scrolling

I'm new and learning to code a website!
I'm trying to do this hover header that when the user scroll down, it will remain on the screen and when the user reaches Sub-Header 1, it will hover it too and changes if the user reaches Sub-Header 2(Sub-Header 1 will then disappear)
This is what I'm working on http://goo.gl/KqAM2R
Thanks in advance!

You need to use JavaScript to achieve this effect. SSCCE:
NewFile.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
<script src="NewFile.js"></script>
<link rel="stylesheet" type="text/css" href="NewFile.css"></head>
<body>
<header class="fixed-top">Europe</header>
<div class="much-text">doge</div>
<header class="whatever1 doge">Heatwave</header>
<div class="much-text">doge</div>
<header class="whatever2 doge">2k15</header>
<div class="much-text">doge</div>
</body>
</html>
NewFile.js:
function isElementInViewport (el, topOrBottom) {
//special bonus for those using jQuery
if (typeof jQuery === "function" && el instanceof jQuery) {
el = el[0];
}
var rect = el.getBoundingClientRect();
if(topOrBottom == "top"){
return rect.top >= 0;
}else{
return rect.bottom <= $(window).height();
}
}
function onVisibilityChange () {
var headers = document.getElementsByClassName("doge");
var headerAbove = null;
for(i = 0; i<headers.length; i++){
$( headers[i]).css("position","");
$( headers[i]).css("top","");
if(!isElementInViewport(headers[i], "top")){
headerAbove = headers[i];
}
}
if(headerAbove != null){
$( headerAbove).css("position","fixed");
$( headerAbove).css("top","30px");
}
}
$(window).on('DOMContentLoaded load resize scroll', onVisibilityChange);
And NewFile.css
#CHARSET "UTF-8";
.fixed-top{
width:100%;
position:fixed;
top:0px;
background-color: red;
}
.whatever1{
width:100%;
background-color: green;
}
.whatever2{
width:100%;
background-color: blue;
}
.much-text{
height: 2000px;
}
.doge {
}
Thanks to authors of answers in How to tell if a DOM element is visible in the current viewport? for an inspiration. Also, I am aware that this code doesn't meet all good practices writing in js & css but OP clearly can find the idea from this one. Notice that you may need to sort headers (from the top header to the bottom header) in your own way before iterating on them in function onVisibilityChange
Try this...
HTML
<div id="page" class="page">
<div class="container">
<div class="contentheadercontainer">
<div class="fsh"><div class="firstheader">Sub header 1</div></div>
<div class="fsh"><div class="secondheader" id='secondheader'><p style='margin-left: 15px;'>Sub header 2</p></div></div>
</div>
</div>
</div>
</div>
CSS
body{
padding: 0px; margin: 0px;
}
.container{
height: 1000px;
}
.fsh{
position: absolute; width: 100%;
}
.firstheader{
height: 30px;width: 100%; position:fixed; background: #B14345; padding: 15px; color: #fff;
}
.secondheader{
border-top: 1px solid #bbb; padding: 5px 0px 5px 0px; margin-top: 300px; width: 100%; background: #B14345;color: #fff;
}
Javascript
document.addEventListener("scroll", function(){
scrollDetect();
});
function scrollDetect(){
var html = document.documentElement;
var top = (window.pageYOffset || html.scrollTop) - (html.clientTop || 0);
if(top > 235){
document.getElementById('secondheader').style.position = 'fixed';
document.getElementById('secondheader').style.marginTop = '60px';
document.getElementById('secondheader').style.width='100%';
}else{
document.getElementById('secondheader').style.position = 'inherit';
document.getElementById('secondheader').style.marginTop = '300px';
}
}

I want to design the dialog in html5. This dialog should accept the freetext and image as parameters. I tried to open dialog as below.. Now I want to pass the parameters so that I can use that dialog everywhere..
