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

How to move several divs up the DOM with jQuery

I would like to move several divs up the DOM with jQuery.
<section>
<div class="title"></div>
<div class="temps"></div>
<div class="list"></div>
</section>
I would like to move all the .list divs after the .title div. How can I do this with jQuery.
This $('.temps').insertAfter('.title'); does not work, it places all the .list after the first .title

I would like to move all the .list divs after the .title div.
You can use each method like this:
$('.list').each(function(){
$(this).insertAfter(
$(this) //.list div
.closest('section') //find parent div section
.find('.title') //find child div
);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section>
<div class="title">title</div>
<div class="temps">temps</div>
<div class="list">list</div>
</section>
<section>
<div class="title">title</div>
<div class="temps">temps</div>
<div class="list">list</div>
</section>
<section>
<div class="title">title</div>
<div class="temps">temps</div>
<div class="list">list</div>
</section>

simply try this, demo
$('.list').insertAfter($('.title'));
or
$('.list').insertAfter('.title'); //only selector no object

Try this
$('.list').each(function(){
$(this).prevAll('.title').after($(this));
});

I wouldn't of been anble to get this working without #Bhojendra Nepal help in his answer above, and while his solution worked in his code snippit it did not work on my application. In the end the below worked for me.
jQuery('.list').each(function(){
jQuery(this).insertAfter(jQuery(this).parent().find('.title'));
});

toggle hide javascript function

I have a div with two divs inside that I want div A to show, with the other hidden. by default I want div A to show
<div id="0">
<div id="A">this is A</div>
<div id="B">this is B</div>
</div>
<div id="1">
<button1>this is 1</button>
<button2>this is 2</button>
</div>
Separate to this is the buttons to action it.
Here is where I got with the javascript:
$(document).ready(function() {
$('.toggle').hide();
$('a.togglelink').click(function() {
$('.toggle').hide();
$(this).parent().next('.toggle').toggle();
return false;
});
});

EXAMPLE
HTML
<div>
<div id="divA" class="toggle">this is A</div>
<div id="divB" class="toggle">this is B</div>
</div>
<div>
<button value="divA">this is 1</button>
<button value="divB">this is 2</button>
</div>
JavaScript
showHideDivs("divA");
$("button").on("click", function(){
showHideDivs(this.value)
});
function showHideDivs(id){
$(".toggle").hide();
$("#" + id).show();
}
Edit: #ShowcaseImagery - I realized that this question was asked specifically for bootstrap and that my solution is more of a JS/jQuery implementation. If you need similar functionality and you're using bootstrap you should look into the collapse accordions. The collapse documentation should outline how to do this correctly.

div0 and div1 is not valid XHTML. I'm guessing that's where your problem is. Instead use the id tag like so:
<div id="div0">YOUR STUFF HERE</div>
<div id="div1">MORE STUFF HERE</div>

Javascript click specific to ID

I have a div setup like so:
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
I have the following code:
$('.show-comments').click(function(e){
e.preventDefault();
$('.comments-wrapper').slideToggle('slow');
});
As you would assume, the code works but on a class basis. I'd like for it to open up only the .comments-wrapper of its associated id (i.e. open slideToggle comments2 if content 2 button is clicked and so on and so on).
How would I do this?

$('.show-comments').click(function(e){
e.preventDefault();
$(this).closest(".content").next('.comments-wrapper').slideToggle('slow');
});
Note that this is dependent on the .content element being immediately followed by the .comments-wrapper.
If you have access to modify the html itself, I would suggest adding a wrapper element and then doing the following to avoid the reliance on the exact order of elements:
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
</div>
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
</div>
$(this).closest(".wrapper").find('.comments-wrapper').slideToggle('slow');
This way, if you add an element between the .content and the .comments-wrapper it does not break the code.

You can do this:
$(this).parent("div").next('.comments-wrapper').slideToggle('slow');
This will find the related div of class .comments-wrapper and slide toggle.
And a fiddle: http://jsfiddle.net/xCJQB/

$('.show-comments').click(function (e) {
e.preventDefault();
var num = this.id.match(/\d+$/)[0];
$("#comment" + num).slideToggle('slow');
});
Demo ---> http://jsfiddle.net/7pkyk/1/

Use this context
$(this).closest('.comments').next('.comments-wrapper').slideToggle('slow');
If it is not the immediate element then you might try this as well
$(this).closest('.comments')
.nextAll('.comments-wrapper').first().slideToggle('slow');

you can add a common class to associate a button with a div.
html:
<div class="content">
<button class="show-comments group1" id="content1"></button>
</div>
<div class="comments-wrapper group1" id="comment1">1</div>
<div class="content">
<button class="show-comments group2" id="content2"></button>
</div>
<div class="comments-wrapper group2" id="comment2">2</div>
javascript:
$('.show-comments').click(function(e){
var associate = $(this).attr('class').match(/group\d+/).pop();
var selector = '.comments-wrapper.' + associate;
e.preventDefault();
$(selector).slideToggle('slow');
});
