If input not existing ( in dataset ) than display generic content - javascript

I'm working on a website with some kind of a JavaScript "input" tabs. Let say user type "running" in input and press submit than application display some quote about running, but when user type something that is not exist in predefined dataset (data-name) than application display generic content.
Everything is working except generic content(class="generic").
How can I add generic content when input value is not existing in dataset values in the app section.
You can try in this fiddle: http://jsfiddle.net/e10nLbg2/1/
Here is my code:
.data, .generic {
visibility: hidden;
opacity: 0;
background: blue;
padding: 50px;
color: white;
transition: opacity 1s ease;
position: absolute;
}
.active {
visibility: visible;
opacity: 1;
}
<input type="text" class="input">
<input type="submit" class="submit" value="SUBMIT">
<section class="app">
<div class="data" data-name="running">RUNNING - Lorem ipsum dolor sit...
</div>
<div class="data" data-name="walking">WALKING - Lorem ipsum dolor
sit...
</div>
<div class="generic">GENERIC - Lorem ipsum dolor sit...
</div>
</section>
var submit = document.querySelector('.submit');
submit.onclick = function(){
var input = document.querySelector('.input').value;
var e = input.toLowerCase();
var element = document.querySelector('[data-name="'+ e +'"]');
var generic = document.querySelector('.generic');
var active = document.querySelector('.active');
if(active){
active.classList.remove('active');
//generic.classList.add('active');
}else{
//generic.classList.remove('active');
}
element.classList.add('active');
}


On submit event you need to remove .active from active element and generic one as well, then set active the one that fits user input, else - set active generic:
var submit = document.querySelector('.submit');
submit.onclick = function() {
let e = document.querySelector('.input').value.toLowerCase();
let element = document.querySelector('[data-name="'+ e +'"]');
let generic = document.querySelector('.generic');
let active = document.querySelector('.active');
if (active) active.classList.remove('active');
generic.classList.remove('active');
if (element)
element.classList.add('active');
else
generic.classList.add('active');
}
.data, .generic {
visibility: hidden;
opacity: 0;
background: blue;
padding: 50px;
color: white;
transition: opacity 1s ease;
position: absolute;
}
.active {
visibility: visible;
opacity: 1;
}
input {
height: 30px;
border-radius: 5px;
box-sizing: border-box;
outline: none;
}
input[type="text"] {
background: #e6e6e6;
color: grey;
outline: none;
padding: 15px;
border: 0;
}
<input type="text" class="input">
<input type="submit" class="submit" value="SUBMIT">

How to change an image when hover over text? (Strictly HTML, CSS and JS)

When an (x) amount of images are located next to (x) different paragraphs, how do I change the image when to a different image entirely when hovering over different paragraphs, as seen on dart.dev by google?

Depending on exactly what the use case is, you can do this without Javascript.
In this snippet the paragraphs and the space for the image are within the same container and then when hovering over a paragraph its associated image is shown as a background image to its before pseudo element which is positioned at the (communal) image position.
body {
overflow-y: hidden;
}
.container {
position: relative;
width: 100%;
}
.container .image, .container p:hover::before {
width: 45%;
height: 100%;
}
.container .image {
display: inline-block;
}
.container div.pwrapper {
width: 45%;
height: 100vh;
display: inline-block;
overflow-y: auto;
}
.container p:hover::before {
position: absolute;
top: 0;
left: 0;
content: '';
background-image: var(--bg);
background-size: cover;
background-position: center center;
background-repeat: no-repeat no-repeat;
}
.container p:nth-child(1) {
--bg: url(https://picsum.photos/id/1015/1024/384.jpg);
}
.container p:nth-child(2) {
--bg: url(https://picsum.photos/id/1016/1024/384.jpg);
}
.container p:nth-child(3):hover {
--bg: url(https://picsum.photos/id/1018/1024/384.jpg);
}

This is indeed done using javascript as evidenced by it not working when you turn off javascript. What you'll want to do is have an img tag and use the javascript mouseover event. You could do something like this:
let img = document.getElementById("img-1");
let link1 = document.getElementById("link-1");
link1.addEventListener('mouseover', () => img.src = 'img1.png');
let link2 = document.getElementById("link-2");
link2.addEventListener('mouseover', () => img.src = 'img2.png');
... (Might want to use a loop)

Changing position from relative to fixed using jquery?

I want the following object to have position fixed, but it has to be located 800 px aprox from top margin below the slideshow, this means outside my screen size.I was told it can be made with jquery- toogle class but can t manage to do it myself - Thanks so much for your help!

<div id="book-now">
<a href="mailto:musictours#zzkrecords.com?subject=Music_Tours"><img
src="book_now.png" alt="" width="90"></img></a>
</div>
#book-now{
position: fixed;
top: 800px;
right: 100px;
width: 160px;
height: 120px;
text-align: right;
}

Basically, you need to measure scrollTop(); and if it goes beyond a certain value (in your case, 800px, in this example - 300px) then give it a fixed position in your id of #book-now
Check it out below:
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 300) {
$(".fixed-header").addClass("fixedPos");
}
else{
$(".fixed-header").removeClass("fixedPos");
}
});
.fixed-header {
background-color: #fff;
width: 100%;
position: absolute;
top: 300px;
left: 0;
}
/*the fixed snippet, triggered by js*/
.fixedPos{
position: fixed;
left: 0;
right: 0;
width: 100%;
z-index: 100;
top: 0;
}
.fixed-header__nav li {
display: inline-block;
list-style-type: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

I assume, you use a normal desktop screen, then its behind your big picture :)
If you add a z-index: 1; it will be above it. Do you realy want it to be always on 800px? On Small devices it never will be within the viewable area.

If you are unfamiliar with JQuery. Try these changes in css;
#header1 {
padding: 20px;
position: relative;
z-index: 100000;
}
.slideshow-container {
max-width: 2000px;
position: relative;
margin: 0px;
z-index: 100000;
}
#book-now{
position: fixed;
top: 550px;
right: 100px;
width: 160px;
height: 120px;
text-align: right;
z-index: 9999;
}

Show hide left navigation?

Im working on a menu that is located on the left side of the screen, and with a button that is located on the main content area i hide/show the menu.
When the screen width is less than 768px i hide the menu using css, the problem that im having is that because the menu is already hided, when the user clicks on the button instead of showing the menu it is trying to hide the menu again.
Im having a lot of troubles trying to explain the problem,
Here is the live demo, with all the code of what I have.
The code works fine for desktop, the problem is when the screen is less that 768px.
This is the function tham using to show/hide the menu and to move the content
$('#menu-toggle').click(function(e)
{
e.preventDefault();
$('#sidebar').toggleClass('show-hide');
$('#page-content').toggleClass('show-hide');
});
CSS
.show-hide
{
margin-left: -250px;
}
Full Code Live Demo: https://jsfiddle.net/c7cpLq9m/

Just added this to the media query:
#wrapper .show-hide {
margin-left: 0;
}
$('#menu-toggle, .mobile-trigger').click(function(e) {
e.preventDefault();
$('#sidebar').toggleClass('show-hide');
$('#page-content').toggleClass('show-hide');
});

Update:
On mobile is better if you not push the content because it will look very messy. It's better to have the menu over the content and add a button inside the menu to close it. For this I added an extra element inside the menu, added the class mobile-trigger, I've hidden it by default on desktop and showed it on mobile using display: block;. Also added the selector mobile-trigger to the click event.

In lonut's answer its better adding this styles:
#menu-toggle {
position: absolute;
top: 0;
right: 10px;
}
To bring the toggle menu button top right of page.

How to show a particular text when clicked on another div?

What I'm trying to do is when someone clicks on the read more button. The rest of the hidden text should show up. To some extent I have been able to achieve what I want with this code. But the problem is when I click on the read more button all the articles are expanded, whereas I just want to expand the particular one which is clicked.
Also I could have used different div names for each article and used the hide show property on it but there are a lot of articles so I can't make my code redundant.
$(document).ready(function() {
$(".hide").hide();
$(".more").click(function(){
$(".hide").show(600);
$(this).hide();
});
});

Also if the text on expanding could fadeIn like a block instead of the animation now it would be better.

Use .next() instead of common class hide
$(document).ready(function() {
$(".hide").hide();
$(".more").click(function(){
$(this).next(".hide").show(600);
$(this).hide();
});
});

Your selector does affect all the elements of .hide class, you need to specify only the one that is in the same <div> as the clicked .more button. Like so:
$(".more").click(function(){
$(this).parent().children(".hide").show(600);
$(this).hide();
});

Fixed vertical navigation menu with dynamically changing menu buttons

I have created a theme for my website with a Fixed vertical navigation menu on the right hand side of the webpage to aid the users to scroll to different sections of the website. Now, these navigation menu buttons help the user in moving to the different sections of the page, but the color of the dots of the menu do not change when we click the dot of a section (or) if we traverse to a section by scrolling up/down. How do you make the color of the dots to change "Dynamically" in the below code? :-

What JavaScript/Ajax/jQuery/HTML/CSS code do I need to write to make it work?
That is how do we "Dynamically" change the { class="is-selected" } on the code :-
<li> <a data-number="2" href="#section2" class=""> <span class="cd-dot"> </span> <span class="cd-label">About</span> </a> </li>
etc etc on the other code sections/ nav sections ??? I guess that would solve the problem

You can do this for the active class (much like #Sachink suggested):
var $navLinks = $('#cd-vertical-nav a');
$navLinks.on('click', function(){
$navLinks.removeClass('is-selected');
$(this).addClass('is-selected');
});
For the scrolling, you need to watch the scroll position in each of your <section>s and when the scrollTop matches a section, set the corresponding menu item's class to is-selected like this:
var windowHeight = $(window).height();
$('section').each(function(){
var $this = $(this);
$(document).scroll(function(){
var scrollTop = $(window).scrollTop();
var offset = $this.offset().top;
var height = $this.outerHeight();
if (offset + height <= scrollTop || offset >= scrollTop + (windowHeight - (height / 2))) {
return;
}
var selector = '[href="#' + $this.prop('id') + '"]';
var $menuItem = $navLinks.filter(selector);
$navLinks.removeClass('is-selected');
$menuItem.addClass('is-selected');
});
});
You can see a working example here: http://jsfiddle.net/5w2bkd6k/2/

You need to add following jQuery code:
<script>
$(document).ready(function(){
$('nav li a').click(function(){
$('nav li a').removeClass('is-selected');
$(this).addClass('is-selected');
})
});
</script>
See fiddle : http://jsfiddle.net/sachinkk/5w2bkd6k/1/
OR
I suggest you to use following code for smooth scrolling
$(document).ready(function(){
$('nav li a').click(function(){
$('nav li a').removeClass('is-selected');
$(this).addClass('is-selected');
event.preventDefault();
var toGo = $(this).attr('href');
$('html, body').animate({
scrollTop: $(toGo).offset().top
}, 1000);
})
});
