Hide element when I click on an other element with jQuery

So i want to have a function to toggle some text under my image.
Here is the script for the toggle :
$(document).ready(function(){
$('.mariage').click(function(event){
event.stopPropagation();
$(".result_mariage").slideToggle("fast");
});
$(".result_mariage").on("click", function (event) {
event.stopPropagation();
});
});
$(document).on("click", function () {
$(".result_mariage").hide();
});
The script is working as intended except when the user click on another link who do an other toggle of information, the toggle stack instead of hidding the last one. If i click anywhere else except another toggle, the information will hide and everything work fine.
( here an image of where i click to trigger the 'bug')
In blue are the other link who toggle stuff
JS Fiddle exemple:
https://jsfiddle.net/karg007/z6y54uro/
sorry if my english is not so good , its not my main language.
Hope those explanation was clear enough for you to help me even if i doubt it :/
Plz dont hesitate to ask more information so i can provide you with what u need to help me.
So to make it short, how do i do to hide my previous toggle when i click my new one?

Edited Answer
So the big issue you're running into OP is that you're not trying to understand the code. A big issue with many new programmers (and unfortunately just as many who have been coding forever) is that they are what I call Copy-Coders. Copying tutorials and answers on stackoverflow may allow you to create your site, complete a few consulting jobs, or even support your whole career but it's not the same as actually knowing how to program.
Doing tutorials and asking questions on SO is perfectly fine (and is in fact how I learned 90% of what I know) but you have to do it with the intent to learn from what you find and not just to complete what you're working on. My advice to you is to really re-read my original answer (I've left it untouched below) and understand how what I showed could be used to accomplish what you want.
With that said, I finish what I start so let's get on with the solution:
I've copied your JSFIDDLE into a Github snippet so you and future users can see the result in the answer. The first thing I immediately noticed is that my code
from the original answer was copied into your existing JS. While this is fine and you correctly changed "text" to "_result", you missed a few things:
My code takes the ID of the clicked element and uses that to look up the id of what should be unhidden. While you correctly changed the lookup code to fit with the ids on your text, you didn't add any ids to the images being clicked on so my code couldn't do anything.
You also didn't remove the 4 functions that you were originally using to implement this feature so it made it look like my code was doing something and working incorrectly, when in fact my code was doing nothing and your code was still doing what it did before (although I definitely see what bug you were talking about before).
Related to my copy-coder rant above, notice how you and I both approached the problem differently and what you can learn from that.
Whereas you wanted to attach a listener function to each item by looking up it's class (which completely unrelated but you aren't using classes correctly and "mariage", etc... fit better as ids which you can still style like classes) I chose to attach a listener to all elements of a single class and then look them up by id.
Your solution requires you to write new JS code for each item you add, and runs the risk of spelling mistakes or forgetting to change something each time you code those functions.
My solution allows you to add as many elements to the HTML as you want and there's no need to change the JS. As long as your images have an id and the text has an id equal to "image id" + "_result" the functionality happens automatically.
I've tried to modify your code as little as possible and only had to delete the 4 functions and add IDs ("mariage" and "amour") to the images in order to get your fiddle to work.
The four functions I removed from your fiddle:
// My toggle code for mariage_result ->text #1
$(document).ready(function() {
$('.mariage').click(function(event) {
event.stopPropagation();
$("#mariage_result").slideToggle("fast");
});
$("#mariage_result").on("click", function(event) {
event.stopPropagation();
});
});
$(document).on("click", function() {
$("#result_mariage").hide();
});
// My toggle code for amour_result ->text #2
$(document).ready(function() {
$('.amour').click(function(event) {
event.stopPropagation();
$("#amour_result").slideToggle("fast");
});
$("#amour_result").on("click", function(event) {
event.stopPropagation();
});
});
$(document).on("click", function() {
$("#amour_result").hide();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
The final code:
// Test code to untoggle the previous element toggled
let lastClicked = null;
$(".hover_selection").click(function() {
if (lastClicked) {
lastClicked.hide();
}
let me = $("#" + this.id + "_result");
me.show();
lastClicked = me;
});
// slick slider option
$(document).ready(function() {
$('.slider_index').slick({
infinite: true,
arrows: true,
centerMode: true,
slidesToShow: 1,
variableWidth: true
});
});

Original Answer
As far as I understand your question, you simply need a variable to keep track of the previously clicked on item. As for what I've done in the demo beloww, I think it's close enough to what you want to do given we don't have a sample to work with. I imagine the only part where you may differ greatly from my example is in how you look up me as I don't know the exact structure of your DOM or what your exact naming scheme is.
let lastClicked = null;
$(".clickable").click(function() {
if (lastClicked) {
lastClicked.hide();
}
let me = $("#" + this.id + "text");
me.show();
lastClicked = me;
});
#root {
width: 300px;
height: 300px;
background-color: black;
}
.text {
display: none;
}
#one {
width: 50px;
height: 50px;
background-color: red;
}
#two {
width: 50px;
height: 50px;
background-color: green;
}
#three {
width: 50px;
height: 50px;
background-color: blue;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="root">
<div class="clickable" id="one">
<p class="text" id="onetext"> 1 </p>
</div>
<div class="clickable" id="two">
<p class="text" id="twotext"> 2 </p>
</div>
<div class="clickable" id="three">
<p class="text" id="threetext"> 3 </p>
</div>
</div>

As far as i understand from your problem, may be this will help.
$(document).ready(function(){
var checker = false;
$('.mariage').click(function(event){
event.stopPropagation();
if(!checker){
$(".result_mariage").hide("slow");
checker = true;
}
else{
$(".result_mariage").show("slow");
checker = false;
}
});
$(".result_mariage").on("click", function (event) {
event.stopPropagation();
});
$(document).on("click", function () {
if(!checker){
$(".result_mariage").hide("slow");
checker = true;
}
else{
$(".result_mariage").show("slow");
checker = false;
}
});
});

Waypoints not working properly with my sidenav

I'm attempting to make a side nav on my site which adds the "active" class to it's four buttons but I cannot seem to make it work properly.
I've successfully added waypoints to the code but they always seem to be a little off and it takes a bit of extra scrolling from the user to activate the waypoint. I've also tried to follow the {offset} rules in the documentation but to no veil. They either stop working properly from last to first or they stop doing so from first to last.
In order to make the sidenav work, I've split the page in columns, as shown in the CSS below. Feel free to provide insight on the code, as this is a learning exercise and I KNOW my code is pretty dirty at the moment (particularly Javascript)
The side nav:
<div class="sidebar verticalized" id="sidebar-verticalized">
<ul id="sidenav" class="side nav-fixed hide-on-med-and-down">
<li class="side-link">
<a class="side-link-first link1" onclick="clickOne()" href="#">01</a>
</li>
<li class="side-link">
02
</li>
<li class="side-link">
03
</li>
<li class="side-link">
04
</li>
</ul>
</div>
The CSS:
html {
overflow: scroll;
overflow-x: hidden;
}
::-webkit-scrollbar {
width: 0px; /* remove scrollbar space */
background: transparent; /* optional: just make scrollbar invisible */
}
.page{
display: grid;
grid-template-columns: 300px auto;
}
.sidebar{
position:fixed;
width:300px;
}
.main{
grid-column-start:2;
}
.verticalized {
margin: 0px;
padding:0px;
float: left;
top: 50%;
transform: translateY(-50%) translateX(-50%);
left:9%;
}
my mess of JS (each section is declared below):
var $section1 = $('.header');
var $section2 = $('.portfolio');
var $section3 = $('.what-we-do');
var $section4 = $('.contact');
var $link1 = $('.link1');
var $link2 = $('.link2');
var $link3 = $('.link3');
var $link4 = $('.link4');
$section1.waypoint(function (){
$link1.addClass('active');
$link2.removeClass('active');
$link3.removeClass('active');
$link4.removeClass('active');
});
$section2.waypoint(function(){
$link1.removeClass('active');
$link2.addClass('active');
$link3.removeClass('active');
$link4.removeClass('active');
});
$section3.waypoint(function(){
$link1.removeClass('active');
$link2.removeClass('active');
$link3.addClass('active');
$link4.removeClass('active');
});
$section4.waypoint(function(){
$link1.removeClass('active');
$link2.removeClass('active');
$link3.removeClass('active');
$link4.addClass('active');
});
What I've tried so far:
Offset: bottom-in-view (sections are sometimes too large and therefore the old active element remains)
Offset: +/- x% (This fixes the issue from one end but not the other one: I could be going from 1 to 4 on links and it works, but 4 to 1 is broken and vice versa)
Any and all advice/tips are welcome. I'm trying to imitate the bootstrap navbar behaviour with active items for each section.

Align list item images to center in html

I'm learning web development with responsive design(still a noob) so please go easy! I will try to be as thorough as possible but please let me know if you need more information!
So I'm trying to design a page which has jquery hover effects on images. You would think I'm having trouble in the JS but my problem is much simpler which makes it frustrating like hell. I want my images to align in the center while they're aligned to the extreme left. the image boxes are li's and I've tried to add them to a div and align the div to the center.
Please note that I also need it to be responsive so can't simply add a margin or padding.
Following is my html body:
<body>
<div class="body">
<div> <img src="images/logo.png" class="image"></div>
<div class="imgs">
<ul id="da-thumbs" class="da-thumbs">
<li>
<a href="http://dribbble.com/shots/502538-Natalie-Justin-Cleaning">
<img src="images/7.jpg" />
<div><span>Natalie & Justin Cleaning by Justin Younger</span></div>
</a>
</li>
<li>
<a href="http://dribbble.com/shots/501695-Cornwall-Map">
<img src="images/9.jpg" />
<div><span>Cornwall Map by Katharina Maria Zimmermann</span></div>
</a>
</li>
</ul>
</div>
</div>
<script type="text/javascript">
$(function() {
$(' #da-thumbs > li ').each( function() { $(this).hoverdir({
hoverDelay : 75
}); } );
});

Your edited code:
.da-thumbs li {
display:inline-block;
width:46%;
margin: 5px;
padding: 8px;
position: relative;
}
.da-thumbs li img{
box-shadow: 0 1px 3px rgba(0,0,0,0.1);
}

You were floating the li's for one thing, also you want to add the box shadows to the images, not the li. The reason for this is that the li is going to be larger than the image, so the box shadow will appear far away from the edges of the actual image. As the screen shrinks, the images will stack. You may need to eventually give the images this styling:
max-width:100%;
so that they don't go off the page at phone width (I didn't look at the size of the images). Hope this helps you.

Can't you do:
margin-left: auto; margin-right: auto;
? This would be responsive, it's not a fixed margin.

how to make transition effects(slide) in autocomplete

autocomplete working fine but i need a transition effect(slide down) in suggested menu,
I referred from this sites http://tutsforweb.blogspot.in/2012/05/auto-complete-text-box-with-php-jquery.html
and i tried
$(document).ready(function() {
$("#tag").autocomplete("autocomplete.php", {
selectFirst: true
});
});
.ac_results {
background-color: white;
border: 1px solid #5c5c5c;
left: 174.5px !important;
overflow: hidden;
padding: 0;
width: 247px !important;
z-index: 99999;
}
.ac_results ul {
width: 100%;
list-style-position: outside;
list-style: none;
padding: 0;
margin: 0;
}
.ac_results li {
margin: 0px;
padding: 2px 5px;
cursor: default;
display: block;
font-family: "armataregular";
font-size: 12px;
line-height: 16px;
overflow: hidden;
}
.ac_loading {
background: white url('indicator.gif') right center no-repeat;
}
.ac_odd {
background-color: #eee;
}
.ac_over {
background-color: #ccc;
color: black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="listone">
<input type="text" placeholder="Enter Keyword" id="tag">
</div>
I added transition property on id="tag" and .ac_results its not working,
please suggest any idea.,

Transitions work by listening to a property and will "animate" when that property changes. So in your case you would need to add a transition to #ac_results. Set the #ac_results height to 0, and when it finds results change the height that element and it should slide down
transition: height 0.5s ease-in-out;
height: 0;
Here is a quick example of it (note that it doesn't do any auto complete, just it shows when input is detected)
http://jsfiddle.net/schwqa7k/1/

center vertical line between divs

I have a div named welcome-inputs and within other two left and right
The div named left needs to be on the left side welcome-inputs and the div named right right side of welcome-inputs.
left and right have width = 100px
Need for a line that is at the MIDDLE of the two, signaling the separation.
view the code: http://jsfiddle.net/gn1asdmh/3/
The red line must be in the middle of the images (the images represent left and right)

jsFiddle demo
Add a span element between .left and .right
<span class="middleLine"></span>
CSS:
.welcome-inputs {
float: none;
margin: 0 auto;
width: 80%;
background:white;
height:100px;
text-align:center; /* ADD THIS */
}
.welcomeforms {
color: #6B6B6B;
margin: 0 auto;
width: 100px !important;
}
.left {
float: left;
/*border-right: 3px solid red; REMOVE THIS */
}
.right {
float: right;
}
body {
background:blue;
}
span.middleLine{
display:inline-block;
border-right: 2px solid red;
margin-left:-1px; /* cause the border is 2px */
height:100%;
}

JSFiddle
The other way to resolve it.
.left {
position:absolute;
top: 0;
left: 0;
}
.right {
position:absolute;
top: 0;
right: 0;
}

If you add position: relative to .welcome-inputs, you can use an ::after or ::before pseudo-element on .left or .right like this:
.left::after {
border-right: 3px solid red;
content: "";
height: 100px;
position: absolute;
top: 0;
left: calc((100% - 3px) / 2); // or use '50%' for better compatibility, but less exactness
}
and get rid of the border-right on .left
JSFiddle Here

Just use generated content on the parent element. There is no reason in the given example to use structural markup for this.
Updated fiddle, http://jsfiddle.net/gn1asdmh/26/
.welcome-inputs {
float: none;
margin: 0 auto;
width: 80%;
background:white;
height:100px;
position: relative;
}
.welcome-inputs::before {
content: '';
display: block;
position: absolute;
outline: 1px solid red;
left: 50%;
width: 0;
height: 100px;
}
.welcomeforms {
color: #6B6B6B;
margin: 0 auto;
width: 100px !important;
}
.left {
float: left;
}
.right {
float: right;
}
body {
background:blue;
}

The cleanest way to do it would be to use an HTML table. This will keep it responsive. Try something like the below code.
.welcome-inputs {
width: 100%;
}
#leftInput,
#rightInput {
width: 100px;
}
#separatorInput {
text-align: center;
}
#dividingLine {
display: inline-block;
height: 100%;
width: 5px;
background: red;
}
<table class="welcome-inputs">
<tr>
<td id="leftInput">
<img width="100%" src="http://news.bbcimg.co.uk/media/images/71832000/jpg/_71832498_71825880.jpg" />
</td>
<td id="separatorInput"><div id="dividingLine"</td>
<td id="rightInput">
<img width="100%" src="http://news.bbcimg.co.uk/media/images/71832000/jpg/_71832498_71825880.jpg" />
</td>
</tr>
</table>

Even better: no need to use any empty/dummy elements. We rely on using pseudo-elements instead. In this case I will use ::before:
.welcome-inputs {
float: none;
margin: 0 auto;
width: 80%;
background:white;
height:100px;
position: relative; /* new property added to original one */
}
.welcome-inputs::before {
content: '';
position: absolute;
top: 0;
bottom: 0;
width: 3px;
background-color: red;
left: 50%;
transform: translateX(-50%);
}
Just remember to declare position: relative on the parent element. See fiddle here: http://jsfiddle.net/teddyrised/gn1asdmh/28/
p/s: You might want to use vendor prefixes for transform, to maximise cross-browser compatibility.

to add some idea to these answers , you may think as well of :box-sizing, calc() for instance , or even a simple background image/repeat/sizing
