Pass multiple ID's to JS function - javascript

My goal in this code is to show specific div tags when the link is clicked and hide all other div tags. I keep rewriting it in different ways but can't seem to get it working properly.
JavaScript below...
function show(id1, id2, id3, id4)
{
document.getElementById(id1).style.visibility="visible";
document.getElementById(id2).style.visibility="hidden";
document.getElementById(id3).style.visibility="hidden";
document.getElementById(id4).style.visibility="hidden";
}
HTML below...
Home
Information
Payment
Contact
<div id="home">Content</div>
<div id="info">Content</div>
<div id="payment">Content</div>
<div id="content">Content</div>

Your code is not working properly because you are passing contact in your function instead of content.
Consider using display:none instead of visibility because if you use visibility your content will be hidden but it will leave a space behind:
function show(id1, id2, id3, id4)
{
document.getElementById(id1).style.display="block";
document.getElementById(id2).style.display="none";
document.getElementById(id3).style.display="none";
document.getElementById(id4).style.display="none";
}
Home
Information
Payment
Contact
<div id="home">Home Content</div>
<div id="info">Info Content</div>
<div id="payment">Pay Content</div>
<div id="contact">Con Content</div>

If this is your html:
<div id="home" class="singleVisible" onclick="disableOthers(this)">Content #1</div>
<div id="info" class="singleVisible" onclick="disableOthers(this)">Content #2</div>
<div id="payment" class="singleVisible" onclick="disableOthers(this)">Content #3</div>
<div id="content" class="singleVisible" onclick="disableOthers(this)">Content #4</div>
Then this could be your script:
function disableOthers(e) {
var all = document.getElementsByClassName('singleVisible');
for(var i = 0; i < all.length; i++) {
// First make all of the elements with the same class hidden.
if (all[i] !== this) {
all[i].style.visibility = 'hidden';
}
// Then make the clicked element visible.
e.style.visibility = 'visible';
}
}
While I feel that it's important that people learn JavaScript this is the sort of thing that jQuery DOES really help with. The 'onclick' attributes above are not recommended for multiple reasons but if you're going to want to remove those and replace them with actual event handler calls in JavaScript then you ALSO are probably going to want to make sure you support older (IE8, not THAT old) browsers as well. Check this out:
http://www.anujgakhar.com/2013/05/22/cross-browser-event-handling-in-javascript/
In any case, the JQuery version is as simple as removing those onclick attributes and using this script instead:
<div id="home" class="singleVisible">Content #1</div>
<div id="info" class="singleVisible">Content #2</div>
<div id="payment" class="singleVisible">Content #3</div>
<div id="content" class="singleVisible">Content #4</div>
<script>
$('.singleVisible').click(function() {
$('.singleVisible').hide();
$(this).show();
});
</script>
Also, note that best practice (if you can) is to have a parent container and attach the event to that instead. Otherwise in both examples I've given you're attaching four event handlers in each case. It's as simple as wrapping the links in a parent div and doing something like this:
<div id="parent">
<div id="home" class="singleVisible">Content #1</div>
<div id="info" class="singleVisible">Content #2</div>
<div id="payment" class="singleVisible">Content #3</div>
<div id="content" class="singleVisible">Content #4</div>
</div>
<script>
$('#parent').on('click', '.singleVisible', function() {
$('.singleVisible').hide();
$(this).show();
});
</script>
Have fun! =)

Give all your div elements a class. On click:
hide all of them by using
getElementsByClassName
https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByClassName
make the particular div visible by its id
Doing these kind of DOM manipulations is very easy with jQuery.

Apply change to all parent elements that contains a certain child element using jQuery

I'm trying to do the same thing as this question but my parent element does not have an id. It does have a class through. Basically I have multiple elements of the same class and some have a child element. If a member of the class example contains the child, apply some CSS change. Is this possible and how would I do it?
For example:
<div class="example">
<div id="findMe"></Div>
</div>
<div class="example">
<!-- This div would not be found -->
</div>
My guess was:
let parents = $(".example");
for (var i=0; i < parents.length; i++) {
if (parents[i].find('#test').length) {
parents[i].css("prop", "value")
}
}
but parents[i].find is not a function
So you shouldn't have multiple instances of the same ID in a document. But in your example, you were pretty close. However, if you're already using jQuery it will make your life a bit easier.
<div class="example">
<div class="findMe"></Div>
</div>
<div class="example">
<!-- This div would not be found -->
</div>
jQuery:
(I'm using the $ to denote a jQuery collection you wouldn't need it)
A jQuery collection (in this case created by find) always has a length. So you need to test if it's empty. Also $.each() is basically looping through the collection.
let $parents = $('.example');
$parents.each(
function(){
var $el = $(this);
if($el.find('.findMe').length !=0){
$el.css('background', 'red');
}
}
);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="height:100px;" class="example">
<div class="findMe">Hello, World!</Div>
</div>
<div style="height:100px;border: solid 1px #000" class="example">
<!-- This div would not be found -->
</div>
As Heretic Monkey said in the comments above, you can use has from jQuery to do this easily.
$(".example").has(".findMe").css("background-color", "red");
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="height:100px;" class="example">
<div class="findMe">Hello, World!</Div>
</div>
<div style="height:100px;border: solid 1px #000" class="example">
<!-- This div would not be found -->
</div>

Collapsible container/column. Adding more than one link

I'm trying to create a drop down effect similar to this image: GIF, however with what I have so far: EXAMPLE I can't seem to figure out a way to add more than one link, if I do add just another content div it doesn't show up.. Hope someone can help, been losing sleep over this haha. Thanks
HTML:
<div class="container">
<div class="header">Projects</div>
<div class="content" onclick="initContent('example')"><em>Example Project</em></div>
</div>
JS:
$(".header").click(function() {
$header = $(this);
//getting the next element
$content = $(this).next();
//checking if its already visible
$content.slideToggle(500, function() {
//execute this after slideToggle is done
//change text of header based on visibility of content div
$header.text(function() {});
});
});
What I would try:
<div class="container">
<div class="header">Projects</div>
<div class="content" onclick="initContent('example')"><em>Example Project</em></div>
<div class="content" onclick="initContent('exampleNew')"><em>Example Project 2</em></div>
</div>
Just put all your links in a single content div:
https://jsfiddle.net/sfcm95yz/3/
<div class="content">
<div class="item" onlclick="initContent('example')">
<em>Example Project</em>
</div>
<div class="item" onlclick="initContent('example2')">
<em>Example Project 2</em>
</div>
</div>
It's because you are sliding down the content div that is right after the header class element ($content = $(this).next();), which applies a display: block to it. If you add another content div, it isn't going to be right after that header and so won't be shown.
You can either change your JavaScript to target all content divs, or rearrange your HTML, something like this:
<div class="container">
<div class="header">Projects</div>
<div class="content">
<div onclick="initContent('example')">
<em>Example Project</em>
</div>
<div onclick="initContent('example')">
<em>Example Project 2</em>
</div>
<div onclick="initContent('example')">
<em>Example Project 3</em>
</div>
</div>
</div>
If you want to modify your JS and keep the existing markup, .nextAll() will select all of $header's siblings (.next() only selects one sibling). You can also add a selector argument to be sure you only select elements with the class "content".
$(".header").click(function() {
$header = $(this);
//getting the sibling ".content" elements
$content = $(this).nextAll(".content");
//checking if its already visible
$content.slideToggle(500, function() {
//execute this after slideToggle is done
//change text of header based on visibility of content div
$header.text(function() {});
});
});

Clone and append on click makes multiple elements and toggle not working

I am trying to clone and append elements. after i append i have added a toggle animation. on first click it works fine. after i am getting mutliple elements appended.
as well the animation not working.
here is the html:
<div class="parent hide">
<div class="header">
<h6>Header</h6>
</div>
<div class="content">
<p>paragraph content </p>
</div>
</div>
<div id="content">
</div>
<button>Add</button>
Js :
$('.parent').on('click', '.header', function () {
$(this).find('h6').toggleClass('name').end()
.siblings('.content').slideToggle();
});
$('button').on('click', function () {
var newParent = $('.parent').clone();
$('#content').append(newParent.removeClass('hide'));
});
JSfiddle
UPDATE:
I updated the cloning passing var newParent = $('.parent').clone(true); - animation works!
you should clone only the first element (or the last for that matter):
var newParent = $('.parent:first').clone(true);
EXAMPLE 1
Using .clone(true) seems to fix the animation. Another solution is targeting the parent on click and delegating .parent .header since the cloned .parent is being added to the DOM after the initial load:
$('#content ').on('click', '.parent .header', function () {
instead of
$('.parent').on('click', '.header', function () {
EXAMPLE 2
Cloning an elements means there will be two identical elements (having the same class aswell) afterwards.
Each time you click the button, all elements having the .parent class are cloned and appended to the #content
Regarding the animation:
The appended elements are not known to the DOM, so the .on('click') is not working.
Try to put a wrapper around your .parent elements and then use the following syntax:
HTML
<div class="wrapper">
<div class="parent hide">
<div class="header">
<h6>Header</h6>
</div>
<div class="content">
<p>paragraph content </p>
</div>
</div>
<div id="content">
</div>
</div>
<button>Add</button>
JS
$('.wrapper').on('click', '.parent .header', function(){ [...] });

When div is clicked - slidetoggle other div

I have a problem with my jQuery code, I want the page to slideToggle one div ones the other is clicked, the problem is that I don't want to write all the code again and again so I tried to create a code that works all the time, but I'm stuck. Box is the div which should be clicked and it should contain a class that's also used on the div that's gonna slideToggle. It should pull the class from the tab and then use it to slideToggle the right object. Please help :S (the elements are not placed close to each other which makes next or children not possible). If you have any questions - ASK!
The jQuery code of mine:
$(".box").click(function() {
var Klassen = $(this).attr("class");
$("Klassen").slideToggle(300);
});
HTML:
<!-- These should be clicked -->
<div data-toggle-target="open1" class="box ft col-lg-3">
<div class="mer">
Läs mer
</div>
<div class="bild"><img src="images/sakerhet.jpg"></div>
<h4>HöstlovsLAN</h4>
</div>
</a>
<div data-toggle-target="open2" class="box st col-lg-3">
<div class="mer">
Läs mer
</div>
<div class="bild"><img src="images/sakerhet.jpg"></div>
<h4>NyårsLAN</h4>
</div>
<div data-toggle-target="open3" class="box tt col-lg-3">
<div class="mer">
Läs mer
</div>
<div class="bild"><img src="images/sakerhet.jpg"></div>
<h4>Säkerhet</h4>
</div>
<!-- These should be toggled -->
<div class="infobox" id="open1">
<h1>HöstlovsLAN</h1>
</div>
<div class="infobox" id="open2">
<h1>NyårsLAN</h1>
</div>
<div class="infobox" id="open3">
<h1>Säkerhet</h1>
</div>
EDIT - NEW PROBLEM - STILL AIN'T WORKING!
The code didn't work in my situation and would like you to take a look at the JS-fiddle I created:
http://jsfiddle.net/Qqe89/
undefined has presented the solution.
I would warn you about using this approach, if you add any classes to the .box div then your code will break.
Instead consider using data attributes to target the div to be toggled:
<div data-toggle-target="open1" class="box green"></div>
<div id="open1">
Opens
</div>
Which can then target with
$('.box').click(function (e) {
$( '#' + $(this).data('toggleTarget') ).slideToggle(300);
});
jsFiddle with example using your html - crudely formatted sorry!
$(".box").click(function() {
var Klassen = $(this).attr("class");
$("."+Klassen).slideToggle(300);
});
class attribute may contain several classes ($(this).attr("class") OR this.className)
$("."+Klassen) will not work if there are several classes
"Klassen" does not correspond to any DOM element as there is no such tag in HTML.

Javascript - jquery,accordion

<div id="wrapper">
<div class="accordionButton">Personal Information</div>
<div class="accordionContent">
Personal text
</div>
<div class="accordionButton">Experience</div>
<div class="accordionContent">
Experience information
</div>
<div class="accordionButton">Training</div>
<div class="accordionContent">
No skills
<div class="accordionButton">Career</div>
<div class="accordionContent">
Never had a job
</div>
<div class="accordionButton">Referers</div>
<div class="accordionContent">
None.
</div>
</div>
This code works how i want it to. It is a horizontal accordion. However, when it is loaded on my webpage, they content divs have to be hidden for my jquery to work.
Jquery:
$(document).ready(function() {
// When div is clicked, hidden content divs will slide out
$('div.accordionButton').click(function() {
$('div.accordionContent').slideUp('normal');
$(this).next().slideDown('normal');
});
// Close all divs on load page
$("div.accordionContent").hide();
});
If i don't hide the divs, all the divs display. Is there any way to display the 1st page without changing too much of my jquery or would i have to set different class names for the button and the content so that when a specified button is clicked, the affiliated content will slide out for that button div?
You can use jquery selector for first div and set it as show(). Something like :
$('div.accordionContent:first').show();
I think you have to try this:-
<script type="text/javascript">
$.fn.accordion = function(settings) {
accordion = $(this);
}
$(document).ready(function($) {
$('div.accordionContent').click(function() {
if($(this).next().is(":visible")) {
$(this).next().slideDown();
}
$('div.accordionContent').filter(':visible').slideUp();
$(this).next().slideDown();
return false;
});
});
</script>
Why not use slideToggle() instead of IF statements....
Try this very simple solution
HTML
<div class="accordion-container">
<div class="accordion-content">
<div class="accordion-title">Title</div>
<div class="accordion-toggle">Toggle content</div>
</div>
<div class="accordion-content">
<div class="accordion-title">Title</div>
<div class="accordion-toggle">Toggle content</div>
</div>
<div class="accordion-content">
<div class="accordion-title">Title</div>
<div class="accordion-toggle">Toggle content</div>
</div>
</div>
jQuery
$('.accordion-content .accordion-title').on('click', function(){
$(this).toggleClass('active');
$('.accordion-title').not($(this)).removeClass('active');
$(this).next().slideToggle();
$(".accordion-toggle").not($(this).next()).slideUp();
});
