I'm finishing my website and I have a script which is hiding or showing a div when a button is pressed.
Here is code :
function display(id) {
var e = document.getElementById(id);
if (e.style.display === "none") {
e.style.display = "block";
} else {
e.style.display = "none";
}
}
But this code is not truly what I'd like because I only want that one div can be displayed at the same time (ex : if div 4 is active and the user need to see the div 2, it has to hide the first one). I have just used JS for quick things therefore I don't have any idea how to do this.
Also would it be possible to hide a specific div depending from which link the user comes on the page.
Exemple of my html :
<a onclick="display('1_1_1')">button</a>
<div id="1_1_1" class="well" style="display: none;">
<h1>Title</h1>
</div>
Thank you for your help !
It is better to add a class which contains display: none like
.no-display {
display: none;
}
then just add or remove that class when you click on a div like
parentDiv.addEventListener("click", function() {
const elem = getElemenyById("elemID");
if(something) {
elem.classList.add("no-display");
else if(something) {
elem.classList.remove("no-display");
};
});
You can create a class with display property and you can add it using Jquery.
CSS:
.display_none_class {
display: none;
}
Jquery:
<script>
$( "#element_ID" ).addClass( "display_none_class" );
</script>
But this sometimes has aligning issues. So, you can use CSS as:
.display_none_class {
width:0;
visibility: none;
}
You can implement this by toggle class:
$("#button_ID").click(function(){
$("#element1_id").toggleClass("display_none_class");
$("#element2_id").toggleClass("display_none_class");
});
First, add this class to the element which you want to hide first. Then On clicking button, it will toggle the class and will make one element visible and other hide.
First add this

I would like to create a curriculum presentation by Java Script similar to the one on Udemy.
https://prnt.sc/22zxxrp
I have tried to put both button and content in the same div and to add an event listener which would on click trigger conditional check if both of the elements are of the same parent and if true to display the content.
But it does not work.
The code would be something like this but with more buttons.
let batonceros = document.getElementsByClassName("batno");
let paragraph = document.getElementsByClassName("para");
batonceros.addEventListener("click", function() {
if( batonceros != paragraph && batonceros.parentNode == paragraph.parentNode) {
batonceros.style.display = "block";
}
else {
batonceros.style.display = "none";
}
});
Not exactly sure what you're trying to accomplish, but maybe this might help. It shows how to reference the parent container to find the relative .para from its .batno
let batonceros = document.querySelectorAll(".batno");
let paragraph = document.querySelectorAll(".para");
batonceros.forEach(button => button.addEventListener("click", e => {
e.target.closest('div').querySelector('.para').classList.toggle('show');
}));
.para {
display: none;
}
.show {
display: block;
}
<div>
<p class='para'>This is a paragraph</p>
<button class='batno'>Button</button>
</div>
<div>
<p class='para'>This is a paragraph</p>
<button class='batno'>Button</button>
</div>
To debug, try to see if it works without checking the parent. Also, no need to check to see if the button equals the paragraph. Also, you are changing the button style, not the paragraph style.
batonceros.addEventListener("click", function() {
paragraph.style.display = "block";
}
If this does cause the paragraph to display, your problem may in your element structure.
I'm trying to make a menu (with buttons) that open links.
when you hover on the buttons, a slideDown reveals more information on that link.
I've gotten all those features to technically work, however i can't get the animation speed to go any slower than instantly.
I'm really new to javascript and Jquery, and it took me 2-3 days to get the javascript and CSS to do what i have so far... and yeah it's probably bloated... but i'm still proud i got this done so far :D
PS, I know most menus are made w/ul's but I really like the way the buttons look and detested trying to put the list together. last time i tried used a seperate ul for the information and it kept styling the second list like the first because it was inside it... so annoying. I also tried vertical-link list w/CSS but still think flat 'buttons' are so boring. i really like the 3D esk of the actual html
HTML:
<div class="mainmenu">
<div id="homemenu">
<button id="home" class="mmbutton active">Home</button>
<div id="homesub" class="sub active">-just a bit about this page</div>
</div>
<div id="photosmenu">
<button id="photos" class="mmbutton">Photos</button>
<div id="photossub" class="sub inactive">-just a bit about this page
</div>
</div>
</div>
javascript/jquery:
$(function(){
var mmbutton = $('.mmbutton');
var start = "http://";
var address = "[my web address"; //add "http:
var about = "[web address]/aboutme.html";
var id = 0;
var rel = 0;
var mmsub = 0;
//<click link buttons:
$(mmbutton).click(function(){
var id = $(this).attr('id');
if (id === "home") {
location.replace(start+address);
}else if (id === "about") {
window.alert("I'm sorry I don't have this page set up yet. Thank you for visiting my page!");
//add additional buttons here under 'else if' unless its a subdomain
}else {
location.replace(start+id+'.'+address);//goes to any subdomain by id
}});
//>detect hover
$(mmbutton).hover(function(){
id = $(this).attr('id');
rel = '#'+id+'sub';
mmsub = '#'+id+'menu';
console.log('mouseenter'+rel);
$(rel).removeClass('inactive');
$(rel).stop().slideDown(500000);
}, function(){
console.log('mouseleave'+rel);
$(rel).addClass('inactive');
if ( $(this).hasClass('active')) {
$(rel).removeClass('inactive');
console.log('this is active');
}if ($(rel).hasClass('inactive')){
$(rel).stop().slideUp(500000);
}});});
relevante CSS:
.inactive {
display: none;
}
.sub {
transition-duration: 1s;
}
You can do it setting all that info divs to display:none and use slideToggle() function for that. Considering you want to keep the subdiv's opened when you're over them, one option is create a span element that include the button and the subdiv, and apply the hover to that span. So...
HTML:
<div class="mainmenu">
<div id="homemenu">
<span class="subcontainer">
<button id="home" class="mmbutton active">Home</button>
<div id="homesub" class="sub">-just a bit about this page</div>
</span>
</div>
<div id="photosmenu">
<span class="subcontainer">
<button id="photos" class="mmbutton">Photos</button>
<div id="photossub" class="sub">-just a bit about this page</div>
</span>
</div>
</div>
CSS:
.sub {
display: none;
/*transition-duration: 1s; IMPORTANT: REMOVE THIS!!*/
}
JQUERY:
$('span.subcontainer').hover(function() {
$(this).find('div.sub').slideToggle('slow');
});
IMPORTANT: Check that to make it work you have to remove the transition style you've created for .sub divs (it interfeers with the jquery function).
NOTE: I don't use the div.homemenu or div.photosmenu as the containers for the hover because div's normally have some styles pre-applied by default and can interfeer with the desired behaviour (for example, they normally have width=100% so the hover applies even when you're outside of the button or subdiv in the same line). span is normally more innocuous to use it just as a wrapper.
I hope it helps
Oh! i got it. i was trying to do too much (show off.../ using what im learning).
I removed the line that added and removed the class 'inactive' and just toggled the SlideUp and slideDown when i wanted it too. now i can adjust the animation speed:
(HTML remains unchanged)
CSS: removed the "transition-duration: 1s;"
JavaScript:
$(function(){
var mmbutton = $('.mmbutton');//any/all buttons
var activebut= 0; //detect button classes
var mmdiv = $("div[id$='menu']");//detect button sub info
var start = "http://";
var address = "[address]/index.html"; //add "http://" + [blog or games] + address
var about = "http://[address]/aboutme.html";
var id = 0;
var sub = 0;
var slidespeed= 450; //slideUP/slideDown animation speed //added var for speed
//<click link buttons: (unchanged)
$(mmbutton).click(function(){
id = $(this).attr('id');
if (id === "home") {
location.replace(start+address);
}else if (id === "about") {
location.replace(start+'[address]/aboutme/index.html')
//add additional buttons here under 'else if' unless its a subdomain
}else {
location.replace(start+id+'.'+address);//goes to any subdomain by id
}
});
//<hover display:
//<detect mouse ON button
$(mmbutton).hover(function(){
id = $(this).attr('id');
sub = '#'+id+'sub';
activebut= $(this);
if ( $(activebut).hasClass('active')) {
}else {
$(sub).stop().slideDown(slidespeed);
}
});
//<detect mouse off button AND div
$(mmdiv).mouseleave(function(){
if ( $(activebut).hasClass('active')) {
}else {
$(sub).stop().slideUp(slidespeed);
}
});
});
I am trying to make webpage where there is a div in the center which is being changed, instead of going to different pages.
Ultimately, I would like to have the new div, when clicking on an arrow, to flow from right or left in to the center. But first I would like to make the divs appear and disappear when clicking on the arrows but unfortunately this doesn't work.
This is my javascript:
<script>
function changeToHome() {
document.getElementById("mainmain").style.display="block";
document.getElementById("mainmain2").style.display="none";
document.getElementById("mainmain3").style.display="none";
document.getElementById("mainmain4").style.display="none";
}
function changeToStudy() {
document.getElementById("mainmain").style.display="none";
document.getElementById("mainmain2").style.display="block";
document.getElementById("mainmain3").style.display="none";
document.getElementById("mainmain4").style.display="none";
}
function changeToJob() {
document.getElementById("mainmain").style.display="none";
document.getElementById("mainmain2").style.display="none";
document.getElementById("mainmain3").style.display="block";
document.getElementById("mainmain4").style.display="none";
}
function changeToContact() {
document.getElementById("mainmain").style.display="none";
document.getElementById("mainmain2").style.display="none";
document.getElementById("mainmain3").style.display="none";
document.getElementById("mainmain4").style.display="block";
}
function changePageRight() {
var displayValue5 = document.getElementById('mainmain').style.display;
var displayValue5 = document.getElementById('mainmain2').style.display;
var displayValue6 = document.getElementById('mainmain3').style.display;
var displayValue7 = document.getElementById('mainmain4').style.display;
if (document.getElementById('mainmain').style.display == "block") {
document.getElementById("mainmain").style.display="none";
document.getElementById("mainmain2").style.display="block";
}
else if (document.getElementById('mainmain2').style.display == "block") {
document.getElementById("mainmain2").style.display="none";
document.getElementById("mainmain3").style.display="block";
}
else if (document.getElementById('mainmain3').style.display == "block") {
document.getElementById("mainmain3").style.display="none";
document.getElementById("mainmain4").style.display="block";
}
else if (displayValue8 == block) {}
}
function changePageLeft() {
var displayValue = document.getElementById('mainmain').style.display;
var displayValue2 = document.getElementById('mainmain2').style.display;
var displayValue3 = document.getElementById('mainmain3').style.display;
var displayValue4 = document.getElementById('mainmain4').style.display;
if (displayValue == "block") { }
else if (displayValue2 == "block") {
document.getElementById("mainmain").style.display="block";
document.getElementById("mainmain2").style.display="none";
}
else if (displayValue3 == "block") {
document.getElementById("mainmain2").style.display="block";
document.getElementById("mainmain3").style.display="none";
}
else if (displayValue4 === "block") {
document.getElementById("mainmain3").style.display="block";
document.getElementById("mainmain4").style.display="none";
}
}
</script>
Now I have a few divs that look like this:
<div id="mainmain4">
<img style="width:400px;height:327px;margin-left:auto;margin-right:auto;display:block;" src="Untitled-22.png" />
<h2> My name </h2>
<p>Hi,</p>
<p>Some text</p>
</div>
With these css atributes:
#mainmain {
float: left;
width: 575px;
display: block;
position: relative;
}
And all other divs with display: none; so I can change this to block and the one that was block to none.
For some reason, after when I click on one button of the menu, which activates a changeToX() function, the arrows work great. But before that, when you first go to the website, it doesn't.
Can someone explain me what I do wrong?
You don't tell the browser which divs shall be displayed on load. You can use theonloadevent for this:
<body onload="changeToHome()">
One additional hint: you maybe don't want to use inline JavaScript and CSS.
jQuery is as this simple:
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
toggle!
<div id="mainmain">test text</div>
<script>
// you need this, only apply javascript when all html (dom) is loaded:
$(document).ready(function() {
$('.toggle-container').on('click', function(e) {
e.preventDefault(); // this prevents the real href to '#'
// .toggle() is like "on / off" switch for hiding and showing a container
$($(this).data('container')).toggle();
});
});
</script>
This function can be reused, because it is based on classes instead of id's.
Check this JSFiddle: http://jsfiddle.net/r8L6xg15/
Maybe this is of some use. I've tried to make a page control-like behaviour. You can select any container div and put elements in there that have the class 'page'. The JavaScript code will let you navigate those with buttons.
You can make it more fancy by adding the buttons through JavaScript. What you then have is basically a list of pages which are normally displayed as regular divs, but when the script kicks in, it changes them to a page control.
You can call this for any parent element, and in that sense it behaves a bit like a jQuery plugin. It is all native JavaScript, though. And not too much code, I hope. Like you said, I think it's good to learn JavaScript at first. It is very powerful by itself, and it's becoming increasingly powerful. jQuery adds a lot of convenience functions and provides fallbacks in case browser don't support certain features, or when implementations differ. But for many tasks, bare JavaScript will do just fine, and it certainly can't hurt to know your way around it.
Press the 'Run this snippet' button at the bottom to see it in action.
function Pages(element)
{
// Some initialization
var activePage;
// Find all pages within this element.
var pages = document.querySelectorAll('.page');
var maxPage = pages.length - 1;
// Function to toggle the active page.
var setPage = function(index)
{
activePage = index;
for (p = 0; p <= maxPage; p++)
{
if (p == activePage)
pages[p].className = 'page active';
else
pages[p].className = 'page inactive';
}
}
// Select the first page by default.
setPage(0);
// Handler for 'previous'
element.querySelector('.prev').onclick = function()
{
if (activePage == 0)
return;
setPage(activePage - 1);
}
// Handler for 'next'
element.querySelector('.next').onclick = function()
{
if (activePage == maxPage)
return;
setPage(activePage + 1);
}
// Add a class to the element itself. This way, you can already change CSS styling
// depending on whether this code is loaded or not. So in case of an error, the
// divs are just all show underneath each other, and the nav buttons are hidden.
element.className = element.className + ' js';
}
Pages(document.querySelector('.pages'));
.pages .page {
display: block;
padding: 40px;
border: 1px solid blue;
}
.pages .page.inactive {
display: none;
}
.pages .nav {
display: none;
}
.pages.js .nav {
display: inline-block;
}
<div class="pages">
<button class="nav prev">Last</button>
<button class="nav next">Next</button>
<div class="page">Page 1 - Introduction and other blah</div>
<div class="page">Page 2 - Who am I? Who are you? Who is Dr Who?</div>
<div class="page">Page 3 - Overview of our products
<ul><li>Foo</li><li>Bar</li><li>Bar Pro</li></ul>
</div>
<div class="page">Page 4 - FAQ</div>
<div class="page">Page 5 - Contact information</div>
</div>
To dos to make this a little more professional:
Add the navigation through JavaScript
Disable the buttons when first/last page has been reached
Support navigation by keys too (or even swipe!)
Some CSS transform (fade or moving) when toggling between pages
Smarter adding and removing of classes. Now I just set className, which sucks if someone would like to add classes themselves. jQuery has addClass and removeClass for this, which is helpful. there are also stand-alone libraries that help you with this.
Visible indication of pages, maybe with tabs at the top?
I have the following working Javascript function:
function collapsible(zap) {
if (document.getElementById) {
var abra = document.getElementById(zap).style;
if (abra.display == "block") {
abra.display = "none";
} else {
abra.display = "block";
}
return false;
} else {
return true;
}
}
When I use the following in html code it displays or hides the "element" div:
<li>Element</li>
Thats working fine. But the problem is, that I want to use the function for multiple links, and then the other elements, that were clicked before, stay, open.
How can I reprogram the code, so that only one div stays open and the other gets closed if i click on another link?
Thanks beforehand!
If you could use jQuery and more importantly jQueryUI accordion I think it would accomplish exactly what you're looking for.
However, without using those two, here is how I would structure it. Like mentioned above, I would use classes to modify the styles of the divs you want shown or hidden. Then the js code can just toggle those classes on each of your elements. The slightly more difficult part (without jquery) is modifying class values since in your final application you may have lots of classes on each div. This is just a very crude example to get you going.
Working JSFiddle Example
Sample DOM
<div >
<li>Element1</li>
<div id='elem1' class='myelem visible'>
Element 1 contents
</div>
</div>
<div >
<li>Element2</li>
<div id='elem2' class='myelem'>
Element 2 contents
</div>
</div>
<div >
<li>Element3</li>
<div id='elem3' class='myelem'>
Element 3 contents
</div>
</div>
Sample JS
window['collapsible'] = function(zap) {
if (document.getElementById)
{
var visDivs = document.getElementsByClassName('visible');
for(var i = 0; i < visDivs.length; i++)
{
visDivs[i].className = visDivs[i].className.replace('visible','');
}
document.getElementById(zap).className += " visible";
return false;
}
else
return true;
}
Sample CSS:
.myelem {
display: none;
}
.visible {
display: block;
}
The way to go is to create a class(or maybe two), like collapsible and active or open that has this style(display: block or none) and then you working adding or removing the class.
The logic would be:
Links that has the class collapsible when clicked would add the active or open class which would give the behavior that remains opens(or active) by css.
If you want to hide others elements you would look for the elements with the class collapsible and then remove the active(or open) class if has any.
Here is my solution: http://jsfiddle.net/g5oc0uoq/
$('.content').hide();
$('.listelement').on('click', function(){
if(!($(this).children('.content').is(':visible'))){
$('.content').slideUp();
$(this).children('.content').slideDown();
} else {
$('.content').slideUp();
}
});
show() and hide() can be used instead of slideUp() and slideDown() if you have performance issues.
i want to show button on div hover.
when i hover mouse on div then button show otherwise hide.
my button in divbutton div.
html
<div class="divbutton">
<button type="button" style="display: none;">Hello</button>
</div>
when I hover mouse on div it should show but how to do that i do not know.
when I remove mouse button again hide.
Thank you.
Use the below selector
button {
display: none; /* Hide button */
}
.divbutton:hover button {
display: block; /* On :hover of div show button */
}
Demo
Also make sure you assign some height or min-height to your div element, else it will be 0 as it doesn't hold any content. Also, don't use display: none; as inline style, as inline styles have highest specificity, and hence, you will be forced to use !important which is bad.
In the above example am using button {/*Styles*/} but that is a general element selector, so make sure you define a class to your button element.
Use following jQuery to perform your task.
Here is a jsfiddle demo
$(document).ready(function () {
$(document).on('mouseenter', '.divbutton', function () {
$(this).find(":button").show();
}).on('mouseleave', '.divbutton', function () {
$(this).find(":button").hide();
});
});
Mr. Alien's answer gives a nice CSS implementation. If you need in jquery, use this -
$( ".divbutton" )
.on("mouseenter", function() {
$("button").show();
})
.on("mouseleave", function() {
$("button").hide();
});
In pure JavaScript -
var buttonDiv = document.getElementsByClassName("divbutton")[0]; //better use some id and then use getElementById
buttonDiv.onmouseover = function() {
document.getElementById("YourButtonId").style.display = 'block';
}
buttonDiv.onmouseout = function() {
document.getElementById("YourButtonId").style.display = 'none';
}
Try this:
$('.divbutton').mouseover(function(event)
{
$(this).find('button').show();
});
$('.divbutton').mouseout(function(event)
{
$(this).find('button').hide();
});
first hide the button with transform property.
button{
transform:translate(100%,100%)
//this will move the button right and buttom
}
then when you hover on div, you bring it back
.divbutton:hover button{
//class name should have been divButton
transform:translate(0,0)}
