Develop Reference

if one item is clicked, remove the other items?

I'm learning Javascript and jQuery and I'm stuck at this one problem. Let's say my code looks like this:
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
Now, if i click one of the div's, i want the other ones to disappear.
I know, I could create 4 functions for each one of them with on.click hey and display none with how , are and you. But is there a easier way? I bet there is, with classes maybe?
Thanks for responding!

Use siblings to get reference to its "brothers".
Given a jQuery object that represents a set of DOM elements, the .siblings() method allows us to search through the siblings of these elements in the DOM tree and construct a new jQuery object from the matching elements.
$('div').click(function(){
$(this).siblings().hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
Or you can hide all the other div which not the clicked element using not
Remove elements from the set of matched elements.
$('div').click(function() {
$('div').not(this).hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>

You can just hide siblings() of clicked div.
$('div').click(function() {
$(this).siblings().fadeOut()
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey">hey</div>
<div id="how">how</div>
<div id="are">are</div>
<div id="you">you</div>

Yeah there are some easier ways and I could tell a one from it,
Set a common class to all the elements that you are gonna target,
<div class="clickable" id="hey"> hey </div>
<div class="clickable" id="how"> how </div>
<div class="clickable" id="are"> are </div>
<div class="clickable" id="you"> you </div>
And you have to bind a single click event by using a class selector,
$(".clickable").on("click", function(){ });
Now use the .siblings() functions to hide the required elements,
$(".clickable").on("click", function(){
$(this).siblings(".clickable").hide();
});
But using a toggle instead of hide would sounds logical,
$(".clickable").on("click", function(){
$(this).siblings(".clickable").toggle();
});
Since you can do the same operation over all the elements.

You can use not to avoid element and this will indicate current instance.
$(document).ready(function(){
$("div").on("click",function(){
$("div").not(this).hide("slow");
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>

Assign a class to each of the elements:
<div id="hey" class='sth'> hey </div>
<div id="how" class='sth'> how </div>
<div id="are" class='sth'> are </div>
<div id="you"class='sth' > you </div>
And write a js function onclick.
Remove class 'sth' from 'this' element in this function
Hide all elements with class 'sth' $('.sth').hide();

For this example - you don't need to add any further selectors to target the div's although in reality - this solution wwould cause all divs on the page to be affectecd - adding classes would be my actual suggestion: - but this works for this example. Click a div and all divs are hidden then the clicked one is shown. I also added a reset button to allow all divs to reappear.
$('div').click(function(){
$('div').hide();
$(this).show();
});
$('#reset').click(function(){
$('div').show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
<hr/>
<button type="button" id="reset">Reset</button>

$(document).ready(function(){
$("div").on("click",function(){
$("div").not(this).toggle("slow");
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>

Only show parent if child contains certain string

I have a group of divs that appear on multiple pages, that have this pattern:
<div class=“entry”>
<div id=“post”>
<div class=“text”>
<div class=“service”></div>
<div class=“timeline”>
<div class=“entry-title”>
#hashtagOne
</div>
</div>
</div>
</div>
</div>
<div class=“entry”>
<div id=“post”>
<div class=“text”>
<div class=“service”></div>
<div class=“timeline”>
<div class=“entry-title”>
#hashtagTwo
</div>
</div>
</div>
</div>
</div>
<div class=“entry”>
<div id=“post”>
<div class=“text”>
<div class=“service”></div>
<div class=“timeline”>
<div class=“entry-title”>
#hashtagThree
</div>
</div>
</div>
</div>
</div>
This group appears on multiple pages.
My ideal javascript/jquery solution is something like this:
display:none on all div class="entry"
if child div class="entry-title" contains #something, change parent div class="entry" to display:block
so that on Page One I can insert this code to only show #hashtagOne, on Page Two only #hashtagTwo, etc. etc.

Try something like this:
$('.entry-title').each(function(i,v){
if ($(this).text().trim().charAt(0) =="#") {
$(this).closest('.entry').show();
}
});
https://jsfiddle.net/0ybstx9o/

This simply works fine :
$(document).ready(function(){
$(".entry").each(function(){
if($(this).find(".entry-title:contains('#something')").length > 0){
$(this).css("display","block");
}
});
});

Its pretty simple, just use :contains() and .closest() together either on page load or whatever event you want this display:block behavior to run.
As you want to show based on differnt pages, I suggest to use page title and set it to title="Page One" and title="Page Two" etc and then compare it in document ready state and show accordingly the desired div
jQuery(document).ready(function(){
jQuery('div.entry').hide();
if(jQuery(document).find("title").text() == 'Page One')
{
jQuery( "div.entry-title:contains('#something')" ).closest('.entry').show();
}
else if(jQuery(document).find("title").text() == 'Page Two')
{
jQuery( "div.entry-title:contains('#something Else')" ).closest('.entry').show();
}
});

$(".entry").find(".entry-title").text(function(key, text) {
if (text.indexOf("#")>=0) {
$(this).parents(".entry").hide()
}
})
Here is the working Plunker

JQuery - Show multiple divs

I'm having some trouble making a working show div and I just can't get it.
So I have the following:
function GetCaptcha() {
$(".panel-captcha").fadeIn(500);
}
Get
<div class="panel-captcha">
TEXT
</div>
The div has the display:none tag.
It works very well, but I have one problem. I need to have many divs inside the same page ( not the same, it may change from database ). If I have 3 or 4 panels, when I click the button it will show them all instead only the div where I have the link to show.
Anyone can help me? Thanks.
Complete HTML file...
<div class="col-md-4">
<div class="panel panel-blue" data-widget='{"draggable": "false"}'>
<div class="panel-heading">
<h2>TEXT</h2>
<div class="panel-ctrls">
<i class="ti ti-eye"></i>
<!-- BUTTON TO SHOW CAPTCHA -->
</div>
</div>
<div class="panel-body">
<small>Other Text...</small>
</div>
<div class="panel-footer">
<div class="tabular">
<div class="tabular-row tabular-row">
<div class="tabular-cell">
<span class="status-total"><strong>More Text...</strong></span>
</div>
<div class="tabular-cell">
<span class="status-pending">Other Text...</span>
</div>
</div>
</div>
</div>
<div class="panel-captcha">
<!-- HIDDEN DIV -->
<div class="tabular-cell">
HIDDEN TEXT
</div>
</div>
<!-- END HIDDEN DIV -->
</div>
</div>

You can pass the reference of element to click handler, then use .next()
Script
function GetCaptcha(elem) {
$(elem).next(".panel-captcha").fadeIn(500);
}
.panel-captcha {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Get
<div class="panel-captcha">
TEXT
</div>
As you are using jQuery bind event using it.
HTML
Get
<div class="panel-captcha">
TEXT
</div>
Script
$(function() {
$('.captcha').on('click', function () {
$(this).next(".panel-captcha").fadeIn(500);
});
});
EDIT
As per updated HTML use
function GetCaptcha(elem) {
$(elem).closest('.panel').find(".panel-captcha").fadeIn(500);
}

jquery select div below parent div

I have a few divs set up like so:
<div class="menu_options">
<div class="parent_div">input field</div>
<div class="children_div">
<div class='something">field</div>
<div class="something_else">field</div>
</div>
</div>
<div class="menu_options">
<div class="parent_div">input field</div>
<div class="children_div">
<div class='something">field</div>
<div class="something_else">field</div>
</div>
</div>
<div class="menu_options">
<div class="parent_div">input field</div>
<div class="children_div">
<div class='something">field</div>
<div class="something_else">field</div>
</div>
</div>
in jquery i am doing
$('.parent_options').each(function() {
$(this).click(function() {
});
});
right now $(this) is giving me the parent_div that i clicked on and I need to be able to move down to the children_div and hide the entire children_div. Any ideas. I know in prototype i used a down function but not sure if jquery has it.

If you want to hide .children_div after clicking on .parent_div use
$('.parent_div').click(function() {
$(this).siblings(".children_div").hide();
});
Demo here

$('.parent_div').each(function() {
$(this).click(function() {
$(this).next().hide();
});
});​

If you're binding the function to all .menu-options, there's no need for each(). This should work if I understood your query properly:
$('.parent_div').click(function() {
$(this).siblings('.children_div').hide();
});

try .next()
$( this ).next( ".tb-contents'" ).show();
This will work.

using jQuery to slide one div down and the other visible divs up (sliding content based navigation)

Figured I would ask here because I can't seem to find an easy solution or a solution on here that fits my needs. The problem I'm having with my site at the moment is when dealing with slide animations and with timing of those animations.
So when a user clicks one of my navigation buttons there is a panel that slides out the content based on the button pressed. if you click another button it will slide that one previous div back up and slide down the new content panel.
The main problem I'm getting is either I get animation timing issues because the other one starts sliding as the other one is for some reason.
All my content panels are siblings to one another...so here's the jQuery I'm using....any suggestions would be greatly appreciated!
$('a.navBtn').click(function(){
var divName = this.name;
$.when(function(){
$("#"+divName).siblings().filter(":visible").slideUp("slow");
}).then(function(){
$("#"+divName).slideDown("slow");
})
});
<div id="services">
<div class="noise_overlay">
<div id="contact"><img src="i/contact.png" /></div>
<div id="linkedin"><img src="i/linkedin.png" /></div>
<div id="facebook"><img src="i/facebook.png" /></div>
<div id="twitter"><img src="i/twitter.png" /></div>
<div id="flickr"><img src="i/flickr.png" /></div>
</div>
</div>
<div id="serviceContent">
<div id="contactContent" class="contentPane mpHidden">
<div class="noise_overlay_300">
<div id="contactData">
<span>contact</span>
</div>
</div>
<div class="contentFooter"></div>
</div>
<div id="linkedinContent" class="contentPane mpHidden">
<div class="noise_overlay_300">
<div id="linkedinData" class="mpCenter">
</div>
</div>
<div class="contentFooter"><span></span></div>
</div>
<div id="facebookContent" class="contentPane mpHidden">
<div class="noise_overlay_300">
<div id="facebookData" class="mpCenter">
<span>facebook</span>
</div>
</div>
<div class="contentFooter"><span></span></div>
</div>
<div id="twitterContent" class="contentPane mpHidden">
<div class="noise_overlay_300">
<div id="twitterData" class="mpCenter">
<span>twitter</span>
</div>
</div>
<div class="contentFooter"><span></span></div>
</div>
<div id="flickrContent" class="contentPane mpHidden">
<div class="noise_overlay_300">
<div id="flickrData" class="mpCenter">
<span>flickr</span>
</div>
</div>
<div class="contentFooter"><span></span></div>
</div>
</div>

You need to chain your animation events so the slideDown doesn't happen until the slideUp is done:
http://api.jquery.com/slideUp/
$("#"+divName).siblings().filter(":visible").slideUp("slow", function() {
$("#"+divName).slideDown("slow");
});
Should be something like that.

I have made a simple jQuery snippet for you. The javascript:
$(function() {
$('a.navBtn').click(function(e) {
var pane = $(this).attr('name'),
switchPanes = function(name) {
if($('.contentPane:visible').attr('id') === name){
return;
}
if($('.contentPane:visible').length > 0){
$('.contentPane:visible').slideUp('fast', function() {
$('#' + name).slideDown('medium');
});
} else {
$('#' + name).slideDown('medium');
}
};
switchPanes(pane);
e.preventDefault();
});
});

Here's a working(?) version. I use the callback of the slideUP to call the slideDown.
