How do i apply a function to only a specific div in a collection of divs generated by foreach loop?

When i click on SHOW MORE in one of the divs generated, in every div the footer div shows up with options Test1, Test2. I want the function to apply to the div im clicking on only. Help please :(
#foreach ($articles as $article)
<div class="row">
<div class="panel-heading">{{$article->title}}</div>
<div class="panel-body">{{$article->content}}</div>
<div class="panel-footer">
<div class="more" onclick="showPortals()">
Show More</div>
<div class="other_sources">Other Sources:
Test 1,
Test 2
<span class="less" onclick="hidePortals()">Show Less</span>
</div>
</div>
</div>
#endforeach
<script>
function showPortals() {
$(".other_sources").show();
$(".more").hide();
}
function hidePortals() {
$(".other_sources").hide();
$(".more").show();
}
</script>

Send the current element to the method
<div class="more" onclick="showPortals(this)">
<span class="less" onclick="hidePortals(this)">Show Less</span>
Use jquery to and hide/show the desired elements
function showPortals(element) {
var $panelFooter = $(element).closest('.panel-footer');
$panelFooter.find(".other_sources").show();
$panelFooter.find(".more").hide();
}
function hidePortals(element) {
var $panelFooter = $(element).closest('.panel-footer');
$panelFooter.find(".other_sources").hide();
$panelFooter.find(".more").show();
}

You can access the object you’re clicking via this object. You can pass it to your function:
<div class="more" onclick="showPortals(this)">
<span class="less" onclick="hidePortals(this)">Show Less</span>
Once you have the object representing your element (here, it will be div and span respectively), you can wrap it inside $ to get a jQuery object. Then, you can use .closest('.panel-footer') on the jQuery object to get your panel footer, and .find(selector) to find relevant objects inside the current panel-footer:
function showPortals(clickedElement) {
var $panelFooter = $(clickedElement).closest('.panel-footer');
$panelFooter.find(".other_sources").show();
$panelFooter.find(".more").hide();
}
function hidePortals(clickedElement) {
var $panelFooter = $(clickedElement).closest('.panel-footer');
$panelFooter.find(".other_sources").hide();
$panelFooter.find(".more").show();
}
However, onclick="hidePortals(this)" is not a recommended way of doing things because you’re mixing JavaScript with HTML. Instead, it’s recommended that you remove onclick="..." handlers and use jQuery’s .click handler, like this:
<script>
$(function() {
$('.more').click(function () {
var $panelFooter = $(this).closest('.panel-footer');
$panelFooter.find(".other_sources").show();
$panelFooter.find(".more").hide();
});
$('.less').click(function () {
var $panelFooter = $(this).closest('.panel-footer');
$panelFooter.find(".other_sources").hide();
$panelFooter.find(".more").show();
});
});
</script>

Change your selector to reflect each record's id.
#foreach ($articles as $article)
<div class="row">
<div class="panel-heading">{{$article->title}}</div>
<div class="panel-body">{{$article->content}}</div>
<div class="panel-footer">
<div class="more-{{$article->id}}" onclick="showPortals({{$article->id}})">
Show More</div>
<div class="other_sources-{{$article->id}}">Other Sources:
Test 1,
Test 2
<span class="less" onclick="hidePortals()">Show Less</span>
</div>
</div>
</div>
#endforeach
<script>
function showPortals(id) {
$(".other_sources-"+id).show();
$(".more-"+id).hide();
}
function hidePortals() {
$(".other_sources").hide();
$(".more").show();
}
</script>

Add a click event to every div:
One way:
$( document ).on( "click", 'div', doSomething);
But if you are trying on an specific id, you may change your selector.

Jquery Dropdown List not sliding up after mouse leave

So I was basically trying to create a drop-down list with jquery. I was successful in achieving but came across with a slight problem. Here's the code
HTML
<div class="dropdown_heading">
text
</div>
<div class="dropdown_container">
<div class="">
Competition1
</div>
<div class="">
Competition2
</div>
<div class="">
Competition3
</div>
</div>
JQUERY
$(document).ready(function(){
$(".dropdown_heading").mouseenter(function(){
$(".dropdown_container").slideDown();
});
$(".dropdown_container").mouseleave(function(){
$(".dropdown_container").slideUp();
});
});
Once I hover over the dropdown_heading the dropdown shows-up and I'm able to navigate over it but the only way the it slides back up is if i actually have the cursor in the dropdown_container. If I try to slide it up removing the mouse from dropdown_heading, the dropdown is still visible. How would I be able to slide the submenu back up when the mouse leaves both div_container and div_heading?
I've tried to execute this function but therefore I am unable to navigate over the container. Thanks.
$(".dropdown_heading").mouseleave(function(){
$(".dropdown_container").slideUp();
});

You can try a timer based solution like
jQuery(function($) {
var $target = $(".dropdown_container");
$('.dropdown_heading').hover(function() {
clearTimeout($target.data('hoverTimer'));
$target.stop(true, true).slideDown(500);
}, function() {
var timer = setTimeout(function() {
$target.stop(true, true).slideUp();
}, 200);
$target.data('hoverTimer', timer);
});
$target.hover(function() {
clearTimeout($(this).data('hoverTimer'));
}, function() {
$(this).stop(true, true).slideUp();
});
});
.dropdown_container {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="dropdown_heading">
text
</div>
<div class="dropdown_container">
<div class="">
Competition1
</div>
<div class="">
Competition2
</div>
<div class="">
Competition3
</div>
</div>

The toggleClass() method toggles between adding and removing one or more class names from the selected elements.
This method checks each element for the specified class names. The class names are added if missing, and removed if already set - This creates a toggle effect..
Try this,
$(document).ready(function(){
$(".dropdown_heading").mouseenter(function(){
$(".dropdown_container").toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="dropdown_heading">
text
</div>
<div class="dropdown_container">
<div class="">
Competition1
</div>
<div class="">
Competition2
</div>
<div class="">
Competition3
</div>
</div>

Toggle multiple classes

I'm stuck with a menu I'd love to add to my website.
I have branched my work in:
Commercial
Fashion
Music
Portrait
So I have a menu like this one above.
When I click on one section, let's say "Commercial" I want all the others to be display:none.
Have a look at this FIDDLE: http://jsfiddle.net/bfevLsj2/8/
$(document).ready(function() {
$("#commercial").click(function() {
$(".commercial").toggleClass("show");
$(".fashion").toggleClass("hid");
$(".music").toggleClass("hid");
$(".portrait").toggleClass("hid");
});
});

You need siblings() width jquery
Description: Get the siblings of each element in the set of matched elements, optionally filtered by a selector.
$("[id]").click(function(){ //onclick on element with ID
var selected = $(this).attr("id"); // save the value of that ID
$("."+ selected).show().siblings("[class]").hide()//find the class with the same value as class and show it then find all siblings class and hide them
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="commercial">Commercial</div>
<div id="fashion">Fashion</div>
<div id="music">Music</div>
<div id="portrait">Portrait</div><br />
<div class="commercial">C</div>
<div class="fashion">F</div>
<div class="music">M</div>
<div class="portrait">P</div>
BUT a better approach would be to use data-*
$("[data-tab]").click(function(){
var current = $(this).attr("data-tab");
$("[data-content="+ current +"]").show().siblings("[data-content]").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div data-tab="commercial">Commercial</div>
<div data-tab="fashion">Fashion</div>
<div data-tab="music">Music</div>
<div data-tab="portrait">Portrait</div><br />
<div data-content="commercial">C</div>
<div data-content="fashion">F</div>
<div data-content="music">M</div>
<div data-content="portrait">P</div>
AGAIN it is better to use pure javascript
function runClick (event) {
var current = this.getAttribute("data-tab");
for( var content = 0; content < dataContent.length; content++) {
dataContent[content].style.display = "none"
}
document.querySelector("[data-content="+ current + "]").style.display = "block"
}
var dataTabs = document.querySelectorAll("div[data-tab]"),
dataContent = document.querySelectorAll("div[data-content]");
for(var tab = 0; tab < dataTabs.length; tab++){
dataTabs[tab].addEventListener("click", runClick , false);
}
<div data-tab="commercial">Commercial</div>
<div data-tab="fashion">Fashion</div>
<div data-tab="music">Music</div>
<div data-tab="portrait">Portrait</div><br />
<div data-content="commercial">C</div>
<div data-content="fashion">F</div>
<div data-content="music">M</div>
<div data-content="portrait">P</div>

HTML:
<div id="commercial" class="menuItem">Commercial</div>
<div id="fashion" class="menuItem">Fashion</div>
<div id="music" class="menuItem">Music</div>
<div id="portrait" class="menuItem">Portrait</div><br />
<div class="commercial content">C</div>
<div class="fashion content">F</div>
<div class="music content">M</div>
<div class="portrait content">P</div>
JavaScript:
$(document).ready(function(){
$(".menuItem").click(function(){
var id = this.id;
$('.content').removeClass('show').addClass('hid');
$('.'+id).addClass('show').removeClass('hid');
});
});
CSS:
.hid {
display:none;
}
.show {
display:block;
}
Fiddle

Have a look at this fiddle, think it's what you want
Essentially you can use .toggle() to traverse and show/hide according to whether it's the one you want to show.
$(function(){
// find all the links that you can click
$("div.clickable a").click(function(e) {
// when they're clicked, find the identifier of
// the tab/div you want shown
var clickedId = $(e.target).parent("div").attr("id");
// traverse all of the divs and show/hide according
// to whether it's the tab you want
$("div.section").each(function(index, div) {
$(div).toggle($(div).hasClass(clickedId));
});
});
});
And the HTML:
<div id="commercial" class="clickable">Commercial</div>
<div id="fashion" class="clickable">Fashion</div>
<div id="music" class="clickable">Music</div>
<div id="portrait" class="clickable">Portrait</div>
<br />
<div class="commercial section">C</div>
<div class="fashion section">F</div>
<div class="music section">M</div>
<div class="portrait section">P</div>
HTH
Edited to add an "ALL" link in this fiddle
$("div.clickable a").click(function(e) {
// when they're clicked, find the identifier of
// the tab/div you want shown
var clickedId = $(e.target).parent("div").attr("id");
// traverse all of the divs and show/hide according
// to whether it's the tab you want
$("div.section").each(function(index, div) {
$(div).toggle($(div).hasClass(clickedId) || clickedId=="ALL");
});
});
After adding this to the list of clickable divs:
<div id="ALL" class="clickable">
ALL
</div>

Your could that more easy like:
<div class="link" id="commercial">Commercial</div>
<div class="link" id="fashion">Fashion</div>
<div class="link" id="music">Music</div>
<div class="link" id="portrait">Portrait</div><br />
<div class="commercial elem">C</div>
<div class="fashion elem">F</div>
<div class="music elem">M</div>
<div class="portrait elem">P</div>
<script type="text/javascript">
$(document).ready(function(){
$(".link").click(function(){
var id = $(this).attr('id');
$('.elem').hide();
$('.' + id).show();
});
});
</script>

same function for same elements

I've got a function that, when you click in a textarea, it will slide down a button.
However, I have multiple textareas on the page with the same class and the problem is that if you click on any of the textareas, all of them will slide down the button.
How can I make it so that it only slides down on the textarea element that you click on, and not the others?
Here's a quick JSFiddle I made: http://jsfiddle.net/MgcDU/6100/
HTML:
<div class="container">
<div class="well">
<textarea style="width:462px" placeholder="Comment..."></textarea>
<button class="btn btn-primary btn-toggle" type="button">Post</button>
<div class="clearfix"></div>
</div>
</div>
<div class="container">
<div class="well">
<textarea style="width:462px" placeholder="Comment..."></textarea>
<button class="btn btn-primary btn-toggle" type="button">Post</button>
<div class="clearfix"></div>
</div>
</div>
JavaScript:
$("textarea").click(function(){
$(".btn-toggle").slideDown();
});
$(document).click(function(e){
e.stopPropagation();
if($(e.target).parents(".well").length == 0){
$(".btn-toggle").slideUp();
}
});

Have to find the elements relative to the element that was clicked.
$(this) is the element that was clicked, and siblings() finds elements that are siblings.
http://jsfiddle.net/P9nMq/
$("textarea").click(function(){
$(this).siblings('.btn-toggle').slideDown();
});
$(document).click(function(e){
e.stopPropagation();
if($(e.target).parents(".well").length == 0){
$(this).find('.btn-toggle').slideUp();
}
});

How about instead of relying on a class lookup, use the event target:
$("textarea").click(function(evtTarget){
$(evtTarget.target).parent().find($(".btn-toggle")).slideDown();
});
http://jsfiddle.net/paulprogrammer/MgcDU/6103/

The following snippet selects all the buttons:
$(".btn-toggle").slideUp();
You should replace it with this:
$(this).siblings(".btn-toggle").slideUp();
Update
I would rewrite your script with these lines :
$(".well").('focus blur', "textarea", function(e){
$(this)
.siblings(".btn-toggle")
.stop(true, true)
.slideToggle();
});
The advantage is that you delegate the events on the same parent of the two targeted elements and that you do not rely on any click event handlers.

Toggle single Div layer using jQuery

At runtime I have a loop that creates a number of divs with the same class depending on the number in the database.
<div class="show">....</div>
<div class="show">....</div>
<div class="show">....</div>
I want to display this div using the slideToggle() function with jQuery. For each of these I have a separate hyperlink which when clicked should display the div. Also there are a number of tags in between the hyperlink and the div that I want to toggle.
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
<div>
<div>
View
</div>
<br />
</div>
<div>
<div class="clear"></div>
</div>
<div class="show">....</div>
$(function () {
$(".display").click(function(){
$(".show").slideToggle();
return false;
});
});
Naturally when this is called each div layer is toggled, regardless of which hyperlink is clicked. I want to just toggle the div closest to the given hyperlink.
Thanks in advance.

Find the <div> relatively by going from this using tree traversal functions, like this:
$(function () {
$(".display").click(function () {
$(this).next().slideToggle();
return false;
});
});
In this case since it's the next sibling element we care about, use .next(), if the structure is different from the question, you'll need to adjust it accordingly, go get from the <a> you clicked on (this) to the <div> you want to toggle.

$(function () {
$(".display").click(function () {
$(this).next.(".show").slideToggle();
return false;
});

Or while you loop through creating your divs, can you add (for example) a rel value that's incremented by one every time? Giving you something like...
View
<div class="show" rel="1">....</div>
View
<div class="show" rel="2">....</div>
View
<div class="show" rel="3">....</div>
This would then link the two divs so that you could get the rel value of your clicked element and use that to identify the shown / hidden div.
<script type="text/javascript">
$(function () {
$(".display").click(function () {
var element_id = $(this).attr('rel');
$(".show").attr('rel', element_id).slideToggle();
return false;
});
});
