How to check if inner <div> has text

what I'm trying to do is to check if my inner <div> has a text for example Ended and then remove if it has a text. I have multiple <div> with the same class name. I tried using .filter(). I would like to remove the div container_one that contains the found element.
Here is my HTML:
var $filstatus = $('.status').filter(function() {
return $(this).text() == 'Ended';
});
$filstatus.remove();
<div class="main_container">
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">On going</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
</div>
Thank you for the help!

I would use the jQuery's selector by content
combined with .closest(). This might be the shortest way:
$('.status:contains("Ended")', $('.main_container')).closest('.container_one').remove();
First ('.status:contains("Ended")') will select all elements that have a class status, contain the text "Ended" and are children of main_container (not needed but is recommended to speed up selection of elements on complex pages).
Then the method .closest('container_one') will climb up the parents tree for each of the elements from the previous step and select the first parent element with class 'container_one'.
At last it will remove all elements found.
Note: all those methods work both with single element and collections of elements, so no need of any for/foreach.
Working JSFiddle Demo

Pure JavaScript solution with forEach:
var div = document.querySelectorAll('.container_one');
div.forEach(function(el){
var target = el.querySelector('.status');
if(target.textContent == 'Ended'){
el.remove();
};
})
<div class="main_container">
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">On going</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
</div>

Try this
$filstatus.parent().parent().remove();

filter will return an array , then use each to loop over that and delete the element. In this case it will remove that specific div but the parent div will still be in dom
var $filstatus = $('.status').filter(function() {
return $(this).text().trim() === 'Ended';
});
$filstatus.each(function(index, elem) {
$(elem).remove();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main_container">
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">On going</div>
</div>
</div>
<div class="container_one">
<div class="inner_container">
<div class="status">Ended</div>
</div>
</div>
</div>

If you want to remove .container_one whose inner child has the text Ended, try
const ended = $('.status').filter((index, element) => $(element).text() === 'Ended')
ended.parents('.container_one').remove()

Since you want to remove the closest ansistor with class .container_one, you will need to use closest
$filstatus.closest(".container_one").remove();
Check this: https://jsfiddle.net/n3d5fwqj/1/
https://api.jquery.com/closest/

Try using this if you don't need $filstatus in other places
$('.status').each(function(){
if ($(this).text() == "Ended"){
$(this).parent().parent().remove();
}
})

I see your problem is you are able to remove the child div status but what you want is to remove the entire parent div with class container_one
you can use $.each for that and use closest(class_name) to remove the parent including its child
$.each($('.status'), function(idx, div) {
if ($(this).text() == 'Ended') {
$(this).closest('.container_one').remove();
}
});
Demo
or you can continue your filter and just add .closest('.container_one') to your jquery selector
var $filstatus = $('.status').filter(function() {
return $(this).text() == 'Ended';
});
$filstatus.closest('.container_one').remove();

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 hide and show when the data matches

I made a snippet and I am working a jQuery show/hide when the data attr matches.
HTML structure is like below
<div class="container">
<div class="item" data-item="1">1
<div class="inside" data-content="1">
</div>
</div>
<div class="item" data-item="2">2
<div class="inside" data-content="2">
</div>
</div>
<div class="item" data-item="2">3
<div class="inside" data-content="3">
</div>
</div>
</div>
the class class="item" will be append (ed) to outside div, I'd like to achieve that,
if content data-num is existing, do not "append()", show()instead, then the slides can be showed properly. I wanted to learn how to check if data-num existing?
so the concept is like that,
if click on class item if item 's data-item(e.g. data-item = "2") matches outside > content data-num (e.g data-num = "2" ), then show() that content class.
Hope I made it clear. Thanks a lot.
Here is online sample: http://jsfiddle.net/8VD9R/

You have to iterate over the content class.
I am writing the sample code here ,Please update it accordingly:
$('.item').click(function(){
$('.content').hide();
$('.content').each(function(i, obj) {
if($(this).attr('data-item')==$(obj).attr('data-num'))
{
$(obj).show();
return;
}
});
});

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;
});
});
