JQuery: Get Text from another <div> only by class

I'm trying to access text from an other div only by classes and with JQuery. I'm always struggling with JQuery because I'm not that familiar with it but for the most times i can get it to work somehow.
I tried something like this:
$(function() {
$(".quote_button").click(
function () {
var text = $(this).parent('.openticket_footer').prev('.openticket_warper').find('.answer_message').text();
alert(text);
}
);});
And many other ways but i cant figure it out.
The easiest way to show you what i want to do is by this picture:
Quote function
I want to click on the class="quote_button"button to access the text in class="answer_message"
Here the html code:
<div class="openticket_warper">
<div class="openticket_sidebar float_left">';
if($result["uID"]==$result_answer["uID"]){
echo '<p style="font-size: 8pt">Ersteller</p>';
}
echo '<p><strong>'. $result_answer["uName"] .' '. $result_answer["Firstname"] .'</strong></p>
<p style="font-size: 10pt">'. $result_answer["pName"] .'</p>
<div class="openticket_sidebar_userpicture">
<img src="images/default-user-icon.png" alt="User Picture">
</div>
</div>
<div class="openticket_ticketmesssage">
<p class="answer_message">'. $result_answer["Message"] .'</p>
</div>
<div class="clear"></div>
</div>
<div class="openticket_footer">
<input class="answerbutton float_right quote_button" type="button" value="Zitieren">
<div class="clear"></div>
</div>
Thank You!

Try this : Get parent using parent method, move to previous div and then find answer_message to get the text
$(function() {
$(".quote_button").click(function () {
var $parent = $(this).parent('.openticket_footer').prev('.openticket_warper');
var text = $parent.find('.answer_message').text();
alert(text);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="openticket_warper">
<div class="openticket_sidebar float_left">';
<p style="font-size: 10pt">Name of the candidate</p>
<div class="openticket_sidebar_userpicture">
<img src="images/default-user-icon.png" alt="User Picture">
</div>
</div>
<div class="openticket_ticketmesssage">
<p class="answer_message">Text Message is here</p>
</div>
<div class="clear"></div>
</div>
<div class="openticket_footer">
<input class="answerbutton float_right quote_button" type="button" value="Zitieren">
<div class="clear"></div>
</div>

$(document).on('click', '.quote_button', function(){
alert($(this).parents('.openticket_warper').find('.answer_message').text());
});

});
});
2) .css
$(this).closest(".cb-window").css("visibility", "visible");
Can someone please show me how to do it? Thank you.
or any other ways using jquery? .show/.hide , .toggle?

The problem was with your way of reaching the proper element and your understanding on closest option of jquery.
As per definition - The closest() method returns the first ancestor of the selected element. An ancestor is a parent, grandparent,
great-grandparent, and so on.
When you say closest on btnSubmit click event, the .cb-window was never its ancestor so $(this).closest('.cb-window') would basically fail. You need to traverse back to btnSubmit's parent who will be sibling of .cb-window and then you can easily get that element. Below is how you can achieve it. Also, you do not need multiple $(function(){ which is equivalent to $(document).ready and only one is sufficient.
$(function() {
$(".btnSubmit").click(function() {
$(this).closest(".ask-button-container").siblings('.cb-window').removeClass("hidden");
//closest ancestor would be .ask-button-container and its sibling is .cb-window
$(this).closest(".my-tab").addClass("hidden");
//did not find .my-tab element in your `html`
});
$(".minus").click(function() {
$(this).closest('.cb-window').addClass("hidden");
$(this).closest(".my-tab").removeClass("hidden");
});
});
.hidden {
display: none;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />

<div id="control-bar">

<iframe id="chatbot-window" name="chatbot-window" scroll="" width="100%" height="100%" frameborder="2" src="{{ 'page1'|page }}"></iframe>
</div>

When we click or do operation on an element we can add or remove class and you can try like this.
$('#elm').hover(
function(){ $(this).addClass('hover') },
function(){ $(this).removeClass('hover') }
)

the problem that you don't target the element you want in a right way .. you need to use
$(function(){
$(".tab-close").click(function() {
$(this).closest(".my-tab").addClass("hidden"); //working
});
$(".tab-expand").click(function() {
var chatbot = $(this).closest('.my-tab').next(".cb-window");
chatbot.removeClass("hidden");
$(this).closest(".my-tab").addClass("hidden"); //working
});
$(".btnSubmit").click(function() {
var chatbot = $(this).closest('div').next().next(".cb-window");
chatbot.removeClass("hidden");
$(this).closest('div').next(".my-tab").addClass("hidden");
});
$(".minus").click(function() {
var chatbot = $(this).closest(".cb-window");
chatbot.addClass("hidden");
chatbot.prev(".my-tab").removeClass("hidden");
});
});
.hidden{
display : none;
}
.minus{
padding : 5px;
background : red;
color: #fff;
text-align : center;
}

Get data from element without id or class

I am building a Chrome extension (and therefore can only use JavaScript) and I need to get the link that resides in the h2 with the heading2 class.
However, there are multiple h2 items with that class (not shown here), and I will not know what the link will point to, as it changes monthly.
In this example, the content of the header is "Think before you tweet". It will always be under another header that contains the words "Featured Topic."
What I am looking to get is the /think_before_you_tweet from the href= of that h2 item. It shows that I have already completed the topic underneath the h2, but that will not always be the case.
Here is the code for the website:
<div class="chosen_for_you_section">
<div class="internal_container">
<h2 class="section_header"><img src="/public/s360/img/360-spinner.png" class="s360LogoHeader">Featured Topic <i class="fa fa-info-circle"></i> <span class="infoTxt">Read about what to do</span></h2>
<article class="article_block masonry_item " data-article_id="431">
<div class="article_image">
<img src="/thumb/public/media/nh/images/twitter_tweet_think_before_send.png?q=&h=278" />
<i class="fa fa-check-square-o article_complete article_type_icon" title="Article"></i>
<div class="action_icons">
<span class="like "><a title="Favorite"><i class="fa fa-heart"></i></a></span>
</div>
</div>
<header>
<h2 class="heading2">Think Before You Tweet!</h2>
<div class="article_required_complete">Congratulations, you've completed this required topic.</div>
<div class="category_blocks">
<p>
Social Media
</p>
</div>
</header>
</article>
<div class="focus_items">
<div class="home_side">
<p>
<img alt="" src="" style="width: 430px; height: 422px;" /><!-- I hid the img src here because it reveals some personal information and is not important -->
</p>
<p></p>
</div>
</div>
</div>
</div>
I can use jQuery in my extension, but I do not have any back-end capabilities.

Use jQuery :contains selector:
$('h2.section_header:contains("Featured Topic") + article a')[0].href

Looks like you've gotta loop through the h2.section_header headers, see if the text matches whatever you want, and then grabs the link from the header following itself.
$('h2.section_header').each(function(index, element) {
var $element = $(element);
if ($element.text().match(/Featured Topic/i)) {
$('#result').html($element.next('article').find('h2.heading2 a').attr('href'));
}
});
#result {
border: 3px solid red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="result"></div>
<div class="chosen_for_you_section">
<div class="internal_container">
<h2 class="section_header"><img src="/public/s360/img/360-spinner.png" class="s360LogoHeader">Featured Topic <i class="fa fa-info-circle"></i> <span class="infoTxt">Read about what to do</span></h2>
<article class="article_block masonry_item " data-article_id="431">
<div class="article_image">
<img src="/thumb/public/media/nh/images/twitter_tweet_think_before_send.png?q=&h=278" />
<i class="fa fa-check-square-o article_complete article_type_icon" title="Article"></i>
<div class="action_icons">
<span class="like "><a title="Favorite"><i class="fa fa-heart"></i></a></span>
</div>
</div>
<header>
<h2 class="heading2">Think Before You Tweet!</h2>
<div class="article_required_complete">Congratulations, you've completed this required topic.</div>
<div class="category_blocks">
<p>
Social Media
</p>
</div>
</header>
</article>
<div class="focus_items">
<div class="home_side">
<p>
<img alt="" src="" style="width: 430px; height: 422px;" /><!-- I hid the img src here because it reveals some personal information and is not important -->
</p>
<p></p>
</div>
</div>
</div>
</div>

with jQuery's :contains selector use this:
jQuery('h2:contains("Featured Topic") ~ article h2.heading2 a').attr('href')
try at http://jsfiddle.net/ug01a0d2/
without jQuery try to bind to class "section_header" or use a cycle with the textContent check to iterate all "h2.section_header"

If there are multiple H2 class heading2 :
$('h2[class*="heading2"] a').each(function(){
var href = $(this).attr('href');
// Do what you want with this href
});

Use XPath! The syntax is pretty, uh, unfortunate, but it's very powerful:
var result = document.evaluate('//h2[#class="section_header"]/following-sibling::article//h2[#class="heading2"]/a', document, null, XPathResult.ANY_TYPE, null );
That should select that anchor node. I'm not sure if it's available to extensions, but Chrome defines a handy helper method called $x that eliminates all that boilerplate around the query.

<a> element not working properly when hiding parent?

I made this script, and despite one oddity, it works fine. It's hiding/showing the parent of div element with a class containing specific content. The problem when I press my <a> elements, that act as buttons, they "filter" the divs, but it leaves the first comment <a>? If I change the element do a <div> instead no problem, but with an <a> element it behaves weirdly? Is this just a bug or?
here is a JSFiddle: https://jsfiddle.net/g1puxhs7/2/
HTML:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
<a class='viewBtn'>Published<a>
<a class='viewBtn'>Completed<a>
<a class='viewBtn'>Created<a>
<div class="orders" id="orders">
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
</div>
<style>
.row {
width: 200px;
margin: 10px;
background: #ccc;
padding: 4px;
}
</style>
SCRIPT:
//--Filter by Status--//
$('.viewBtn').click(function() {
var txt = $(this).text();
$('.status:contains("' + txt + '")').parent().toggle();
$(this).toggleClass('down');
});

The problem is with your links:
<a class='viewBtn'>Published<a>
<a class='viewBtn'>Completed<a>
<a class='viewBtn'>Created<a>
You have 6 opening a tags, instead of 3 opening and 3 closing tags.
This is why the browser adds closing a tags in your script in a bunch of places, one of them in your first div—and then your whole DOM tree looks different than what you want.

Your markup needed to be cleaned up. Here is your markup cleaned up. Also, i find it best to add href for you anchor tags, and then you can comment them out with #, or you can add javascript:void(0). If you use the # approach, in your JS, you can add e.preventDefault();
HTML Cleaned:
<div>
<a class='viewBtn' href="#">Published</a>
<a class='viewBtn' href="#">Completed</a>
<a class='viewBtn' href="#">Created</a>
</div>
<div class="orders" id="orders">
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff" onclick="Comment">Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff">Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff">Comment</a>
</div>
</div>
JS with preventDefault():
$('.viewBtn').click(function(e) {
e.preventDefault();
var txt = $(this).text();
$('.status:contains("' + txt + '")').parent().toggle();
$(this).toggleClass('down');
});

Minor tweak to this javascript function?

I have a script that shows/hides used via onClick. I can get it to show/hide just fine, but I can't get it to show/'hide everything else'. So what I get is a bunch of open containers when I really want just the one.
Javascript:
<script>
function showfields(fields){
if(document.getElementById(fields).style.display=='none'){
document.getElementById(fields).style.display='block';
}
else{
document.getElementById(fields).style.display = 'none';
}
}
</script>
HTML:
<div id="hidden" class="steps" style="display: block;">
<div class="section" style="margin-right: 10px;">
<h2>Something</h2>
</div>
<button class="continue dropdown" id="showLink" onClick="showfields('hidden2');return false;" href="#">Continue</button>
</div>
<div id="hidden2" class="steps" style="display: block;">
<div class="section" style="margin-right: 10px;">
<h2>Something2</h2>
</div>
<button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button>
</div>
<div id="hidden3" class="steps" style="display: block;">
<div class="section" style="margin-right: 10px;">
<h2>Something3</h2>
</div>
<button class="continue dropdown" id="showLink" onClick="showfields('hidden3');return false;" href="#">Continue</button>
</div>
<div id="hidden4" class="steps" style="display: block;">
<div class="section" style="margin-right: 10px;">
<h2>Something4</h2>
</div>
<button class="continue dropdown" id="showLink" onClick="showfields('hidden4');return false;" href="#">Continue</button>
</div>
Thanks

Since you've tagged this with jQuery I assume that is an option:
function showfields(fields){
$('.steps').hide()
$('#' + fields).show();
}

Edit:
Is this what you're trying to do: http://jsfiddle.net/Rykus0/67cjt/2/
(without jQuery)
(ps - this can be done better)
Your question is not very clear, but I'm guessing that you want the page to start with the everything but the first div hidden.
In that case, what you have is fine, just set style="display:none;" on the elements you don't want to show at first (you can also use a class).
Also, I believe you should change the onclick call on hidden3 to be showfields('hidden4') and remove the onclick event from hidden4

I agree with Porco,
Another option would be using a class as a flag, for example
function showFields(fields){
$(fields).each(function(){
if($(this).hasClass('visible'){
$(this).hide();
}
else {
$(this).show();
}
}
}

Without using jquery .This piece of javascript may help you
<script>
function showfields(fields){
for(var i=0;i<document.body.getElementsByTagName("*").length;i++)
{ if(document.body.getElementsByTagName("*")[i].id==field)
{
document.body.getElementsByTagName("*")[i].style.display='block';
}
else{
document.body.getElementsByTagName("*")[i].style.display='block';
}
}
</script>
