Can't select the siblings of an element using jQuery - javascript

I've tried seemingly every combination of .siblings, .parents().siblings, with and without $(this). or just 'this', and I can't for the life of me get jquery to select the sibling of an element that's clicked on.
Here's the relevant html:
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>
Here's the relevant jquery that i've gotten to work, but it selects and opens every single instance of that class on the page:
$('.opener').click( () => {
if(clickCount == 0){
$('.hideShow').css('visibility', 'visible');
$('.hideShow').css('position', 'static');
Any form of $(this), $(this > '.hideShow'), $(this).siblings(), or $(this).parents('.showButton').siblings() seems to have zero effect, whether it's my design or from the internet. The JS you see above is literally the only thing that will affect the page in any way.
I have multiple of these .opener classes on the page, and I'd just like to change the CSS on the sibling of the clicked element. Am I going about this the wrong way?
edit: It currently selects every instance of the class, as that's the only thing that works in any way.

$('.hideShow') will match all .hideShow, instead you need to use this and find the .hideShow within its parent.
$('.opener').click(function(e) {
const hideShow = $(e.currentTarget).parent().find('.hideShow');
hideShow.css('visibility', 'visible');
hideShow.css('position', 'static');
});
.hideShow {
visibility: hidden;
}

<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>

Please use the below approach. Use next() to select the next element or prev() to select the previous element. And use normal function then arrow function to bind the this keyword.
jQuery(document).ready(function() {
let clickCount = 0;
$('.opener').click(function() {
if (clickCount == 0) {
$(this).next().css('visibility', 'visible');
$(this).next().css('position', 'static');
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow' style="visibility: hidden;">Code tag</code>
</div>

When opener element click you need to first find the parent, for that you can use closest() and after that, you find the hideShow element and apply your CSS over that.
Try below code-
$('.opener').click(function() {
$('.hideShow').hide()
const hideShow = $(this).closest('.showButton').find('.hideShow').show();
});
.hideShow {
display: none;
}
<script src="https://code.jquery.com/jquery-3.4.1.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>
<div class='showButton'>
<p class='opener'>Get The Code</p>
<code class='hideShow'>Code</code>
</div>

JavaScript code not working with multiple HTML elements

I've build myself a sign input on my website inside a modal popup. The problem is that I can have an unknown amount of modals generated in a foreach within PHP. Because of this my JavaScript code don't works anymore. Do you have any idea how I can improve my function to make it workable for a undefined amount of signature modals?
var signaturePad;
jQuery(document).ready(function () {
jQuery(document).on('opened', '#sign-modal', function () {
var signaturePadCanvas = document.querySelector('.signature-pad-canvas');
var parentWidth = jQuery(signaturePadCanvas).parent().outerWidth();
signaturePadCanvas.setAttribute("width", parentWidth);
signaturePad = new SignaturePad(signaturePadCanvas);
jQuery('#clear-signature').click(function () {
if (signaturePad) {
signaturePad.clear();
}
});
});
});

The reason why your modals have stopped working is because each modal you create is created with the same id.
This means that when you access the element with DOM, only the first element would be returned. Using a class is not the best idea as you lose the ability to target specific elements without looping.
The best solution in my opinion is to dynamically generate the id as you create your modals. This means you could have something like sign-modal-1, sign-modal-2 etc for each modal you create.
Then, in JQuery, you target elements with ID's that get opened, that begin with sign-modal, i.e. using the JQuery attribute selector.

Hide div when input is empty

I need to hide a div when an input element is empty (the user has not typed anything in). I have tried this and this but they do not work for me. the div I want to hide has an id of search-result-container and the input has an id of search-input. I need to hide the div when the input is empty.
Here is the relevant part of my HTML code:
<!-- Html Elements for Search -->
<div id="search-container">
<input type="text" name="search-input" id="search-input" placeholder="🔎 type to search...">
<h1></h1>
<h1></h1>
<h1></h1>
</div>
</div>
<h1></h1>
<h1></h1>
<h1></h1>
<h1></h1>
<div class="container" id="search-result-container" class="show_hide">
<ul id="results-container"></ul>
<!-- Script pointing to search-script.js -->
<script src=[SEARCH JS]></script>
<!-- Configuration -->
<script>
SimpleJekyllSearch({
searchInput: document.getElementById('search-input'),
resultsContainer: document.getElementById('results-container'),
searchResultTemplate: '<h1>{title}</h1><h2 class="searchresults">{date}</span></h2>',
json: [JSON URL]
})
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</div>
</div>
Any help will be very much appreciated, Thank you in advance.
Here is a very simple way of doing what you want using jquery:
$('#search-input').on('input', function() {
$('#search-result-container').css('display', $(this).val() !== '' ? 'block' : 'none')
});
#search-result-container {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id ="search-input">
<div id="search-result-container">This will be hidden</div>
Based on both links you post:
HTML:
<input id="search-input" type="text" placeholder="Write here"/>
<div id="search-result-container" class="hide">
<p>
Results...
</p>
</div>
CSS:
.hide {
display: none
}
JS:
$('#search-input')
.on('keyup', function(e) {
var input = $(this).val();
input.length ?
$('#search-result-container').show() :
$('#search-result-container').hide();
})
JSFIDDLE
Use This Way:
<script>
// Your div id which you wants to hide
var hide = document.getElementById("yourDivId");
//Your input field id
var textarea = document.getElementById("YourInputFieldId");
//Simple Logic
if (textarea.value == "") {
hide.style.display = "none";
}
</script>

Getting the selector, not the handler

HTML:
<div id="div1">
<div class="close">close</div>
</div>
<div id="div2">
<div class="close">close</div>
</div>
jQuery:
$('.close').on('click', '#div1, #div2', function(){
console.log ( $(this) ); // .close
});
If I have multiple elements with close buttons, how do I get the parent element as this and not the button?
So if I click the .close on #div1, I need #div1 as this to work with it.
By instinct, I would look to closest, which takes a selector as a param:
var selector = '#div1, #div2';
$('.close').on('click', selector, function(){
console.log ( $(this).closest(selector) ); // .close
});
.closest will return a jQuery object representing first node that matches the selector. It starts with the current object and continues to .parent() until it finds a match
since the element is a child of the element you want to reference, use a parent selector.
$(this).parent().hide()
Most of the time we would use a class on the element and use closest to select it.
$(this).closest('.msg').hide()
$('.close').on('click', function(){
$(this).closest(".msg").hide();
});
.msg{
.border: 1px solid black
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1" class="msg">
<div class="close">close</div>
<p>test 1</p>
</div>
<div id="div2" class="msg">
<div class="close">close</div>
<p>test 2</p>
</div>
You actually don't need any selector, just a .closest("div").
If you want to be a bit more specific like "The closest ID starts with div" than you could do like:
$('.close').on('click', function(){
$(this).closest("[id^='div']").fadeOut();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1">
<div class="close">close1</div>
</div>
<div id="div2">
<div class="close">close2</div>
</div>
Or, by doing it the way you started you could use the event.delegateTarget -
which refers to the actual selector-delegators $('#div1, #div2')
$('#div1, #div2').on('click', '.close', function(event) {
$(event.delegateTarget).fadeOut();
});
// or use also for brevity:
// $("[id^='div']").on(...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1">
<div class="close">close1</div>
</div>
<div id="div2">
<div class="close">close2</div>
</div>

two division put the details in inner div using jquery

i have 2 divisoin
<div id="details">
<div id="feature">
</div>
</div>
I need to put the content using $("#details").html(content); (it is working correctly) like that way i need to put the content inside feature div i am using following way:
$("#details #feature").html(content);
but it is not working..how to solve?
When you use $("#details").html(content); you override the content of the div. So you're inner div with the id feature gets removed. Maybe you use $("#details").prepend(content); or you add another div for the main content and replace that content.
Look here is an example:
https://jsfiddle.net/morrisjdev/s9u7rfcu/
ID is a unique attribute so you can directly use id like below.
$(function() {
var content = "Some text here";
$('#feature').html(content);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="details">
<div id="feature">
</div>
</div>
OR
$(function() {
var content = "Some text here";
$('#details').find('#feature').html(content);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="details">
<div id="feature">
</div>
</div>
$(document).ready(function(){
var htmldetail ="Hello! I am Here";
var details = $("#details").html(htmldetail);
$("#userfeature").html(details);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<div id="details">
<div id="userfeature">
</div>
</div>
The second is #feature and not #userfeature. And also add the jQuery Library as well. You can replace test with content variable.
$("#feature").html("test");
<div id="details">
<div id="feature">
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
And also remember Id is unique and hence no need to mention its parent.
Run the following snippet and you can get the output.
Simple way..Go Through this
HTML
<div id="details">
<div id="feature">
</div>
</div>
JQUERY
$(document).ready(function()
{
var content="contain sample data";
// $("#details").html(content); if you wrote like this,
this will replace all content, so the inner div will be replaced
$("#details").append(content); // outer div
$("#feature").html(content);
});
Or you can use css-like selector method:
$(document).ready(function() {
$('#details > #feature').html('Hello <strong>World!!!</strong>');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="details">
<div id="feature">
</div>
</div>
I have created a plunk for it and it is working.
Try including the action inside
$( document ).ready(function() {
console.log( "ready!" );
var content = 'Hey there';
$("#details #feature").html(content);
});

How do I show and hide dive on button click in html css trick?

I have responsive Html website
I want to hide and show on click of next in simple html
DEMO PAGE
Q1.WHAT IS YOUR NAME
ANS - JAMES
Q2.WHAT IS YOUR ADDRESS
ANS- PUNE
here Q1 and Q2 are on the same page but
I want to show only one question at a one time but do not want to create multiple physical pages.
I tried using hide and show trick of css but I want to do it on simple html button click NEXT
want output like following
Q1.WHAT IS YOUR NAME
ANS- JAMES
[CLICK NEXT]
it will load Q2 on same page.
I tried not using one page with different pages like below.
<link rel='stylesheet' type='text/css' href='css/style.css' />
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'></script>
<script type='text/javascript' src='js/jquery.ba-hashchange.min.js'></script>
<script type='text/javascript' src='js/dynamicpage.js'></script>

<li>Q2</li>
</ul>
</nav>
<section id="main-content">
<div id="guts">
Q1.WHAT IS YOUR NAME
ANS - JAMES
</div>
</section>
Using just Javascript you can do this fairly easily. Something like this should work:
HTML
<label id="name">What is your name?<input type="text" /></label>
</br>
<label id="address">What is your address?<input type="text" /></label>
</br>
<button id="next">Next</button>
CSS
#address {
display: none;
}
Javascript
document.getElementById('next').onclick=function(){
document.getElementById('address').style.display='block';
};
Here is a fiddle: http://jsfiddle.net/YJRbE/
Or, if you'd prefer to use jQuery, something like this:
$('#next').on('click', function() {
$('#address').show();
});
Here is a fiddle for the jQuery version: http://jsfiddle.net/XyNXq/
Here some example with jQuery which supports more than two questions:
Try to wrap all your questions in a div and use jquery for the click event so each time you click the button a next question will appear.
In this method you should include all your questions inside the wrapper div and set their display to none.
http://jsfiddle.net/ZFZfY/1/
Edit: http://jsfiddle.net/ZFZfY/3/
HTML:
<div class="questionWrapper">
<div class="question show" id="questionOne">
<label>foo bar?</label>
<input type="text">
</div>
<div class="question" id="questionTwo" style="display: block;">
<label>foo bar?</label>
<input type="text">
</div>
</div>
<a class="NextQuestion" href="#">Next Question</a>
CSS:
.question{ display: none;}
.show{ display: block;}
jQuery:
$('.NextQuestion').click(function(e){
e.preventDefault();
loadNext();
});
$('.PrevQuestion').click(function(e){
e.preventDefault();
loadPrev();
});
function loadNext(){
// loop to verify what is visible
$('.questionWrapper').children().each(function(i){
if($(this).css('display') === 'block' && $(this).next().length > 0){
$(this).css('display','none');
$(this).next().fadeIn();
return false;
}
});
}
function loadPrev(){
// loop to verify what is visible
$('.questionWrapper').children().each(function(i){
if($(this).css('display') === 'block' && $(this).prev().length > 0){
$(this).css('display','none');
$(this).prev().fadeIn();
return false;
}
});
}
here is script
<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-migrate/1.2.1/jquery-migrate.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('.content').each(function() {
var $this = $(this);
$this.find(':not(.col:first,.active)').hide();
$('.col').children().removeAttr('style');
});
$("#add").click(function() {
$(".col:hidden:first").show("slow");
$('.col').prev().hide();
});
});
</script>
here demo html
<div class="content">
<div class="col">
<h3>What Is Your Name</h3>
<input type="text">
</div>
<div class="col">
<h3>What Is Address</h3>
<input type="text">
</div>
<button id="add" class="active">Add</button>
</div>
Hope this helps.
You can change the visibility of elements on button click like this.
document.getElementById('name').style.display='none';
document.getElementById('address').style.display='block';
Here is the working demo
