Expand / Show and hide div element in a listview - javascript

As you can see, is this a list view and my mission is when you click on an element / div then the div with the images expand / show. Now that is easy, even for a backend developer, but I would like to:
1. when I click again on the same element, then the element will hide.
2. When I click on another element, then the element that is already expand will hide and the other element that I click on, will expand / show.
I need Script and CSS for this please.
<div class="row">
#foreach(var post in CurrentPage.Children)
{
<div class="col-md-12">
<div class="content equal" onclick="showhide()">
<a href="#post.Url">
<div class="date">#post.CreateDate.ToLongDateString()</div>
<h2>#post.Name</h2>
<p>#Umbraco.Truncate(post.Introduction, 240, true)</p>
</a>
</div>
<div class="images(-expand)">
<img src="#post.Image" />
</div>
</div>
}
</div>

Try as follows.
$('.content.equal').click(function() {
$('.content.equal').not(this).next().slideUp();
$(this).next().slideToggle();
});
$('.content.equal a').click(function(event) {
event.preventDefault();
});
.images {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-12">
<div class="content equal">
<a href="#post.Url">
<div class="date">12-01-2017</div>
<h2>Name1</h2>
<p>#Umbraco.Truncate(post.Introduction, 240, true)</p>
</a>
</div>

whats the best way to control showing and hiding multiple charts and divs in a page

I am new in javascript,i have a page consist of different Card layouts and each card has its own chart or buttons or grids,some of them should be hidden by default and some of them should be hide or visible by click,since the page is growing by more demands ,controlling these hid/e/show is becoming a nightmare,i would like you tell me whats the best way to do this?for example i have a following div which has a chart:
<section style="width:100%;margin-top:2%;" >
<div id="btnCurrentStatID" class="card ShowHide" style="float:right;width:20%;height:350px;display:none;">
<div class="wrapper">
<div class="containerBtns" style="width:100%;float:right" >
<button type="button" id="btnErrorStat" class="btnsForCrew-Common "></button>
<button type="button" id="btnIdle" class="btnsForCrew-Common "></button>
<button type="button" id="btnService" class="btnsForCrew-Common "></button>
<button type="button" id="btnLinkDn" class="btnsForCrew-Common"></button>
<button type="button" id="btnDataIn" class="btnsForCrew-Common" ></button>
<button type="button" id="btnrepOff" class="btnsForCrew-Common"></button>
</div>
</div>
</div>
<div id="faultStatChartID" class="card ShowHide" >
<div id="chart">
</div>
</div>
<div id="pieChartID" class="card ShowHide">
<div id="pieChart"></div>
</div>
</section>
<section style="width:100%;float:left;margin-top:3%;" id="faultStatSubGroupsSec">
<div id="subcatNameChartSectionID" class="card" style="width:49%;float:left;display:none">
<div class="container">
<div id="subcatNameChart"></div>
</div>
</div>
<div id="subcatErrorChartSectionID" class="card" style="width:49%;float:right;display:none">
<div class="container">
<div id="subcatErrorChart"></div>
</div>
</div>
<div id="subCatIdnameSectionID" class="card" style="width:49%;float:left;display:none">
<div class="container">
<div id="subCatIdname"></div>
</div>
</div>
<div id="subCatITurNameSectionID" class="card"style="width:49%;float:right;display:none">
<div class="container">
<div id="subCatITurName"></div>
</div>
</div>
<div></div>
<div></div>
</section>
i gave it showhide class,and by default its hidden,when i click on filter button it will be visible,and other divs should be hidden,it this continues,imagine how many time i should do it and manage to control them all,
$(".ShowHide").css("display", "block");
$("#subcatNameChartSectionID").hide();
$("#subcatErrorChartSectionID").hide();
$("#subCatIdnameSectionID").hide();
$("#subCatITurNameSectionID").hide();
A way would be to use a class for hiding.
.hide {
display: none;
}
And a hideable class for accessing every item that should be able to be hidden. The class hide can be added to hide the element.
<div class="hideable">1 hideable</div>
jQuery offers methods for class manipulation:
$('.hideable').toggleClass('hide');
$('#unique4').removeClass('hide');
$('#unique5').addClass('hide');
Here is the full snippet code:
$('.hideable').toggleClass('hide');
$('#unique4').removeClass('hide');
$('#unique5').addClass('hide');
.hide {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="unique1" class="hideable">
1 hideable
</div>
<div id="unique2" class="hideable">
2 hideable
</div>
<div id="unique3" class="hideable hide">
3 hideable
</div>
<div id="unique4" class="hideable hide">
4 hideable
</div>
<div id="unique5" class="hide">
5 other

Trying to filter non-hovered elements with jquery

I have an image gallery. Basically I am trying to go for something that lets the hovered image maintain its styling properties but the background (non-hovered images, I should say) filter to grayscale.
This is my first project and I am trying to push myself. I am making some mistakes but learning from each one. Your help is appreciated.
HTML:
<section id="image-gallery">
<div class="container">
<div id="imageboxing" class="disciplines">

<div class="imagetext">

JQUERY:
$(document).ready(function() {
$(".disciplines img").hover(function(){
var images = $(".disciplines img");
$(this).toggleClass("active-image");
$(this).css("cursor", "pointer");
$(this).next().find('h3').slideToggle();
if (images.not(".active-image") {
$(images).css("filter", blur("20px"));
}
});
You have to do it like below:-
$(document).ready(function() {
$("#image-gallery img").hover(function(){ // on hover of image
$(this).toggleClass("active-image");
$(this).css("cursor", "pointer");
$(this).parent().css({"filter": ""}); //remove it's parent filter css
$('img').not($(this)).parent().css({"filter":'blur(5px)'}); //add filter css to all othe images parent-div apart from thr current clicked-one
}, function () { //when hover-out
$('.disciplines').css({"filter": ""}); //remove filter css from all div
});
});

Hide parent div class if child div class does not have content when there are multiple parent divs with the same class name

I have a slider where some of the images in the slider can have an optional photo- credit containing text or link in a popper. I would like to iterate over all of the popper instances and if all of the p tags in the .photo-credit p class are empty, then hide only that instance of the parent popper. I've tried to piece together a solution from some other posts, but have not been able to get it to work. The code I have does not hide a popper if all p tags are empty for that popper. I'm a JavaScript newbie and would appreciate any help.

JavaScript
$('.popper').each(function () {
//var $thisPopper = $(this);
var hasContent = 0;
$('.photo-credit p').each(function () {
if($(this).html().length > 0) {
hasContent++;
}
});
if(hasContent > 0){
//$thisPopper.hide();
$(this).hide();
}
});
You were on the right direction. However a couple mistakes in your javascript.
You tried to target all the div with "popper" class. However, the div with "popper" and "photo-credit" are on the same level. Why not targeting their parent div instead?
Try this code. It's been tested (Link to jsfiddle)
$('.slider-item').each(function () {
var thisSilerItem = $(this);
var hasContent = 0;
thisSilerItem.find('.photo-credit p').each(function () {
if($(this).html().length > 0) {
hasContent++;
}
});
if(hasContent <= 0){
thisSilerItem.find('.popper').hide();
}
});
Edit:
Bonus:
If your page has a large amount of sliders, this jquery solution will cause some UX issues ("jumpy" div on/after page load)
Try a CSS only solution.
When you render your DOM elements. Add a class to "popper" div if the content of "photo-credit" is empty.
<div class="popper hide">
// img
</div>
Then in your CSS, add
.popper.hide { display: none; }
It's hard to fully gather what you want to do, but if I understand correctly...
$('.popper').each(function () {
var photoCredit = $(this).find(".photo-credit p")
if ( $(photoCredit).is(':empty') ){
$(this).hide();
}
});
It's worth pointing out that CSS4 developers are working on a 'has' selector but as of July 2017 there is no support for any browser just yet.
It is expected to work in the following manner:
.popper:has(> p:empty) { display: none }
I hope this helps... :)
You can check this code.
$.each($('.popper'), function (index, popper) {
var isEmptry = true;
$.each($(popper).next('.photo-credit').children(), function (index, ptag) {
if ($.trim($(ptag).html()) != '')
isEmptry = false;
});
if (isEmptry)
$(popper).hide();
});
Working code
$.each($('.popper'), function (index, popper) {
var isEmptry = true;
$.each($(popper).next('.photo-credit').children(), function (index, ptag) {
if ($.trim($(ptag).html()) != '')
isEmptry = false;
});
if (isEmptry)
$(popper).hide();
});

What I'm trying to do is when I click Photography, it will change the font color and when I click Graphics, the photography color would go back to black and graphics would now be the colored font.
function chgfont(type){

if(type=="A"){
document.getElementById("colorA").style.color ="blue";
// document.write("<font color=\"blue\">Font colors is blue</font>");
}else{
document.getElementById("colorA").style.color ="red";
// document.write("<font color=\"red\">Font colors is red</font>");
}
}

I hope i can help you.
I would suggest a little different formation of your function. Select the .btn elements and, depending on the clicked element, get the id and perform your actions.
As for the font color, write up a css rule giving the desired color and simply add, or remove this class form the respective elements:
jQuery
$('.btn').on('click', function() {
var that = $(this);
var id = that.attr('id');
//Remove .colored class form all .btn elements
$('.btn').removeClass('colored');
//Add .colored class to the clicked element
that.addClass('colored');
var ph = $("#photography");
var gr = $("#graphics");
//Permorm the appropriate action depending on the clicked id
if (id == '#hideshow1') {
ph.slideToggle("slow");
gr.slideUp("slow");
} else if (id == '#hideshow2') {
gr.slideToggle("slow");
ph.slideUp("slow");
}
});
CSS
.colored { color:red }
