I need to hide a div from DOM when specific class included in middle of the html code. Please take a look at this example.
<body>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
</body>
I tried to achieve this with jQuery .closest() but no luck.
$( ".text-block" ).closest( ".first-group" ).css( "color", "red" );
Any solution?
if($(".second-group span").hasClass("text-block")) {
$('.first-group').css('display', "none");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
</body>
Simply if the length of .text-block inside the wrapper is greater then 0 then simply make .first-group display: none.
if($( ".wrapper" ).find( ".text-block" ).length > 0){
$('.first-group').css( "display", "none" )
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
If you have multiple .first-group and .wrapper then you can simply loop the wrapper and find its parent and previous element of that parent.
$( ".wrapper" ).find( ".text-block" ).each(function() {
$(this).parents('.wrapper').prev('.first-group').css( "display", "none" );
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
You can try with parents() and siblings() like the following:
$(".text-block").parents('.wrapper').siblings('.first-group').css( "color", "red" );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div class="first-group">
<h1>Hello world</h1>
</div>
<div class="wrapper">
<div class="second-group">
<div class="main">
<div class="small">
<span class="text-block">Hello mars</span>
</div>
</div>
</div>
</div>
</body>
The use of closest will only look for its ancestor, while .first-group is outside the .wrapper div.
In the below code, we are finding the ancestor of the element and then use prev() to get previous element with class .first-group
$(this).closest("div.wrapper").prev(".first-group").css('display', 'none');
See if it works.
Your basic problem is that closest() looks for an ancestor. .text-block is not a descendant of .first-group . Use prev() to find the previous sibling of the containing block.
In response to your comment prevAll works if there are intermediate siblings. I've added a few empty divs to the example to demonstrate. I need to check some fringe cases.
To get this a bit more robust I've used prevUntil to limit the sibling selection combined with prev to find the actual element of interest.
$( ".text-block" ).closest( ".wrapper" ).prevUntil(".first-group").prev().hide();

I have a list of 12 posts wrapped in a div tag and the structure looks like this:
<div class="row">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
Is there a way I can loop every third div with the class of content in another div tag?
At the end I would have my structure like this:
<div class="row">
<div class="wrapper">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
<div class="wrapper">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
<div class="wrapper">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
<div class="wrapper">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
</div>
Is there a way I can loop every third div with the class of content in another div tag?
You can do something like this
// get all element at position 1,4,7,...etc and iterate
$('.row .content:nth-child(3n + 1)').each(function() {
$(this)
// get all siblings next to it
.nextAll('.content')
// get only next 2 elements from it
.slice(0, 2)
// combine the current element with it
.add(this)
// wrap all elemnts with the div(3 divs)
.wrapAll('<div class="wrapper">')
})
$('.row .content:nth-child(3n + 1)').each(function() {
$(this).nextAll('.content').slice(0, 2).add(this).wrapAll('<div class="wrapper">')
})
console.log($('.row')[0].outerHTML)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
Or you can use jQuery :lt() pseudo-class selector to avoid slice() method.
$('.row .content:nth-child(3n + 1)').each(function() {
$(this).nextAll('.content:lt(2)').add(this).wrapAll('<div class="wrapper">')
})
$('.row .content:nth-child(3n + 1)').each(function() {
$(this).nextAll('.content:lt(2)').add(this).wrapAll('<div class="wrapper">')
})
console.log($('.row')[0].outerHTML)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
Loop through the children, every third child create a new wrapper and add each child in the respective wrapper.
var test = document.querySelector("#test");
var index = 2;
for (var child of test.querySelectorAll(".content")) {
if (index++ >= 2) {
var newWrapper = test.appendChild(document.createElement("div"));
newWrapper.className = "wrapper";
index = 0;
}
test.removeChild(child);
newWrapper.appendChild(child);
}
console.log(test.innerHTML);
<div class="row" id="test">
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
<div class="content">
</div>
</div>
Try this
function WrapUpAllDivs(){
var CurrentDivs = $(".row",".content");
for(var i = 0; i < CurrentDivs.length -1 ; i+=3) {
CurrentDivs
.slice(i, i+3)
.wrapAll("<div class=\"wrapper\"></div>");
}
}
This question already has answers here:
jQuery find an element by its index
(7 answers)
Closed 4 years ago.
I was wondering how I could add a class to a specific object inside a list?
Let me demonstrate the question with some code.
$('.box')[5].addClass('center')
.center{
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="box">
c-1
</div>
<div class="box">
c-2
</div>
<div class="box">
c-3
</div>
<div class="box">
c-4
</div>
<div class="box">
c-5
</div>
<div class="box">
c-6
</div>
<div class="box">
c-7
</div>
<div class="box">
c-8
</div>
<div class="box">
c-9
</div>
</div>
This does not work because I get an error:
Uncaught TypeError: $(...)[5].addClass is not a function
I only want to add the class to the fifth element of the list. What can I do?
$('.box') is an object not an array. So you can not use index like that.
You can simply use eq() selector which selects the element at the specified index within the matched set:
$('.box:eq(5)').addClass('center');
.center{
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="box">
c-1
</div>
<div class="box">
c-2
</div>
<div class="box">
c-3
</div>
<div class="box">
c-4
</div>
<div class="box">
c-5
</div>
<div class="box">
c-6
</div>
<div class="box">
c-7
</div>
<div class="box">
c-8
</div>
<div class="box">
c-9
</div>
</div>
In JQuery there is something called the eq selector
Select the element at index n within the matched set.
Here is how to use it in your instance (remember counting starts at 0)
$('.box:eq( 5 )').addClass('center')
.center {
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="box">
c-1
</div>
<div class="box">
c-2
</div>
<div class="box">
c-3
</div>
<div class="box">
c-4
</div>
<div class="box">
c-5
</div>
<div class="box">
c-6
</div>
<div class="box">
c-7
</div>
<div class="box">
c-8
</div>
<div class="box">
c-9
</div>
</div>
I hope you find this helpful.
I'm trying to hide the outer div when a nested div is empty (including white-space node). I've found a solution that works if there is NO whitespace:
Hide parent DIV if <li> is Empty
I need it to work when there IS white space present, ie:
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"> </div>
</div>
</div>
</div>
Example fiddle
Working fiddle
You could use the both :empty and :contain() selector :
$("div.product:contains(' '), div.product:empty").closest('div.wrapper').hide();
Hope this helps.
$("div.product:contains(' '), div.product:empty").closest('div.wrapper').hide()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"> </div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Visible if working 2</div>
<div class="content">
<div class="product">text</div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 3</div>
<div class="content">
<div class="product"></div>
</div>
</div>
</div>
You can iterate over each div.product and trim the text to remove whitespace. If there's anything left, show it, otherwise, hide its wrapper.
$("div.product").each(function() {
if ($(this).text().trim() == '') {
$(this).closest('div.wrapper').hide()
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 1</div>
<div class="content">
<div class="product"></div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Visible if working 2</div>
<div class="content">
<div class="product">text</div>
</div>
</div>
</div>
<div class="gen-customer">
<div class="wrapper">
<div class="heading">Hidden if working 3</div>
<div class="content">
<div class="product"></div>
</div>
</div>

//Try this using Jquery

Is there anyway i can find the current class number?
For example: Total elements with class 'TEST' are 20. $('.TEST').length
If i click on 4th test element i should get 4.
I played with index but couldn't get it to work.
Please look the example below.
<div class="a">
<div class="b">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="e">
<div class="f">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="k">
<div class="t">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
.....
Jquery
$(document).on('click','.TEST'){
.....
}
I think this is what you're looking for. Sounds like you were close.
$(function () {
$('.TEST').click(function () {
console.log($('.TEST').index(this));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="a">
<div class="b">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="e">
<div class="f">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="k">
<div class="t">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
Note, click on fourth .TEST element should return 3, as .index() uses 0-based index
$(document).on('click', '.TEST', function(e) {
console.log($(this).index(".TEST"))
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="a">
<div class="b">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="e">
<div class="f">
<div class="TEST">CLICK ON THIS.</div>
</div>
</div>
<div class="k">
<div class="t">
<div class="TEST">CLICK ON THIS.</div>

I have a following html as follows:
<div class="outerdiv">
<div class="title">
<div class="innerdiv">
<div class="outerdiv">
<div class="title">
<div class="innerdiv">
<div class="outerdiv">
<div class="innerdiv>
<div class="outerdiv">
<div class="title">
<div class="innerdiv">
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
I have to apply "border-width:10px" for all divs with class = innerdiv provided that "outerdiv" contains both "title" and "innerdiv"
.
My expected output is:
<div class="outerdiv">
<div class="title">
<div class="innerdiv" style="border-width:10px">
<div class="outerdiv">
<div class="title">
<div class="innerdiv" style="border-width:10px">
<div class="outerdiv">
<div class="innerdiv>
<div class="outerdiv">
<div class="title">
<div class="innerdiv" style="border-width:10px">
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
I am trying this:
$(element).find(".outerdiv").not("[class="title"]).css("border-width","10px").
Edit: The number of divs are dynamic and not fixed in number
You need to use :has selector along with immediate child selector to target innerdiv element:
$('.outerdiv:has(.innerdiv):has(.title) > ,.title > .innerdiv ').css("border-width","10px");
DEMO SNIPPET :
$(function(){
$('.outerdiv:has(.innerdiv):has(.title) > .title > .innerdiv ').css("border-width","100px").css('border' ,'1px solid grey')
}) ;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="outerdiv">
<div class="title">1
<div class="innerdiv">2
<div class="outerdiv">3
<div class="title">4
<div class="innerdiv">5
<div class="outerdiv">6
<div class="innerdiv">7
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
You can do this with good css hierarchy just apply the styles to
.outerdiv > .title > .innerdiv{
css goes here
}
and they will only affect divs in the hierarchy that you mentioned.
Simply use:
$('.innerdiv').css('border-width','10px');
It will add border-width to all divs with class 'innerdiv'.
