I have a bunch of inline-block divs on my web page,
<div class="container">
<div class="text">Text 1</div>
<div class="text">Text 2</div>
<div class="text">Text 3</div>
<div class="text">Text 4</div>
<div class="text">Text 5</div>
<div class="text">Text 6</div>
<div class="text">Text 7</div>
</div>
and they wrap around like this:
I want to be able to delete the first row of them, that is in this case 1-5. But if I scale this to where only 1-3 are in the first row, I would only like to delete those. (you get it)
I don't have any clue what kind of javascript can be applied for this particular use case, but for simplicity, heres the JSFiddle. I would rather not use JQuery.
If the width of each item is the same, you can get the width of container, divide by the width of each item (to determine the number of items in each row), then delete that many items from the start.
const item = document.querySelector('.text');
const itemWidth = item.offsetWidth + 2 * parseFloat(window.getComputedStyle(item).getPropertyValue("margin"));
const containerWidth = document.querySelector('.container').offsetWidth;
const itemsInFirstRow = Math.floor(containerWidth / itemWidth);
document.querySelectorAll('.text').forEach((e,i) => {
if(i < itemsInFirstRow) e.remove()
})
.text {
height: 50px;
width: 50px;
background-color: red;
display: inline-block;
margin: 5px;
color: white;
text-align: center;
}
.container{
width:200px;
}
<div class="container">
<div class="text">Text 1</div>
<div class="text">Text 2</div>
<div class="text">Text 3</div>
<div class="text">Text 4</div>
<div class="text">Text 5</div>
<div class="text">Text 6</div>
<div class="text">Text 7</div>

I have the following structure example:
<div class="main">
<div class="image">Image1</div>
<div class="image">Image2</div>
<div class="image">Image3</div>
</div>
<div class="side">
<div class="Banner">Banner1</div>
<div class="Banner">Banner2</div>
<div class="Banner">Banner3</div>
<div class="Banner">Banner4</div>
</div>
I want to make a script that will take each banner and placed under each image.
<div class="main">
<div class="image">Image1</div>
<div class="Banner">Banner1</div>
<div class="image">Image2</div>
<div class="Banner">Banner2</div>
<div class="image">Image3</div>
<div class="Banner">Banner3</div>
<div class="Banner">Banner4</div>
</div>
<div class="side"></div>
Basically there are some images placed one after another and then some banners placed one after another.
Image1
Image2
Image3
Banner1
Banner2
Banner3
Banner4
I need to take each banner and place it under each image so I can have:
Image1
Banner1
Image2
Banner2
Image3
Banner3
Banner4
I cannot change the html to manually placed the banners, I need to use a more advanced script JS and or jquery ..
.content {display:flex; max-width:800px;min-width:300px;gap:20px;margin:auto;}
.main { flex: 70%;}.main2 {max-width:400px;}
.side { flex: 30%; padding:10px;}.img { background:blue;}.banner { background:red;}
.img, .banner { width:100%; min-width:50px; height:50px;display:grid;place-items:center; color: #fff; margin:10px auto;}

To do what you require you can loop through the .banner elements and use their index to place them underneath the related .img element by their indexes using insertAfter(). Something like this:
let $imgs = $('.content .main .img');
$('.content .side .banner').each((i, el) => $(el).insertAfter($imgs[i]));
.content {
display: flex;
max-width: 800px;
min-width: 300px;
gap: 20px;
margin: auto;
}
.main {
flex: 70%;
}
.img,
.banner {
width: 100%;
min-width: 50px;
height: 50px;
display: grid;
place-items: center;
color: #fff;
margin: 10px auto;
}
.img {
background: blue;
}
.banner {
background: red;
}

Well, to answer my own question, it was hard for me since I don't know JS that well.
I managed to make something that also randomizes the banners and I've used jquery.
jQuery("#btn").click(function() {
var cards = jQuery(".side .banner");
for(var i = 0; i < cards.length; i++){
var target = Math.floor(Math.random() * cards.length -1) + 1;
var target2 = Math.floor(Math.random() * cards.length -1) +1;
cards.eq(target).before(cards.eq(target2));
}
cards = jQuery(".side .banner");
var images = jQuery(".content.desk .img");
if (cards.length < images.length) {
for (var i=0; i<cards.length; i++) {
images.eq(i).after(cards.eq(i));
}
} else {
for (var i=0; i<images.length; i++) {
images.eq(i).after(cards.eq(i))
}
for (var i=images.length; i<cards.length; i++){
cards.eq(i-1).after(cards.eq(i));
}
}
});

Original:
You need to loop over the elements and then merge/combine the arrays as you are looping. There are multiple ways this can be done. Here's one way (with comments) that uses reduce to combine the elements.
If you're starting out with JS, I would suggest using a simple for loop to start off.
When you run the code snippet below, the original will be in Red. Clicking the button will merge the elements, append them, and display them in Green.
Good luck!
// I've wrapped this in a function so I can call it.
function rearrange() {
// First I'm going to query all the divs with 'img' class
// From that, I'll call 'Array.from' to create an array.
const images = Array.from(document.querySelectorAll('.img'));
// Similar to above, but for all the 'banner' divs.
const banners = Array.from(document.querySelectorAll('.banner'));
// This is my loop. I'm using .reduce, but for/while/.forEach/etc
// would all have worked.
// I'm going to loop over the images and push image/banner into
// a new container
const container = images.reduce(function (el, image) {
// get the first "banner" div
const banner = banners.shift();
// append the image div, first
el.appendChild(image);
// if a banner exists, append that
if (banner) {
el.appendChild(banner);
}
// as this is a reducer, i return my accumulator of divs
return el;
}, document.createElement('div'));
// As image/banner could differ in length, push any additional
// banner divs to the container
if (banners.length > 0) {
banners.forEach(banner => container.appendChild(banner));
}
// Add the new class name
container.classList.add('main2');
// Finally, append to body
document.querySelector('.body').appendChild(container);
}
// My event handler to run
document.querySelector('#rearrange').addEventListener('click', rearrange);

<h2>Rearranged:</h2>

</div>
first sorry if you don't understand the title
I have a list that contains elements
once I click on an item, "s" class must be added to it and removed from others
I try to remove by loop but didn't work
function selectIt(x) {
x.classList.add('s');
var items = document.querySelectorAll('item');
for (i = 0; i < items.length; i++) {
items[i].classList.remove('s');
}
}
.s {
background: red;
}
<div class="list">
<div class="item" onclick="selectIt(this)">item 1</div>
<div class="item s" onclick="selectIt(this)">item 2</div>
<div class="item" onclick="selectIt(this)">item 3</div>
<div class="item" onclick="selectIt(this)">item 4</div>
<div class="item" onclick="selectIt(this)">item 5</div>
</div>
You are not defining the type of selector in querySelectorAll like you want to search for a class or id.
Add the s class at the end and not in the beginning, as defining it in the start will remove the s class from the current element also.
Also, you can search for s class in the querySelector instead of searching for item.
function selectIt(x) {
var items = document.querySelectorAll('.s');
for (i = 0; i < items.length; i++) {
items[i].classList.remove('s');
}
x.classList.add('s');
}
.s {
background: red;
}
<div class="list">
<div class="item" onclick="selectIt(this)">item 1</div>
<div class="item s" onclick="selectIt(this)">item 2</div>
<div class="item" onclick="selectIt(this)">item 3</div>
<div class="item" onclick="selectIt(this)">item 4</div>
<div class="item" onclick="selectIt(this)">item 5</div>
</div>
You don't have to run a loop at all. First, remove the class s from the previous div element and add it to the new div element which is clicked.
function selectIt(x) {
let item = document.querySelector('.s');
item.classList.remove('s')
x.classList.add('s');
}
.s {
background: red;
}
<div class="list">
<div class="item" onclick="selectIt(this)">item 1</div>
<div class="item s" onclick="selectIt(this)">item 2</div>
<div class="item" onclick="selectIt(this)">item 3</div>
<div class="item" onclick="selectIt(this)">item 4</div>
<div class="item" onclick="selectIt(this)">item 5</div>
</div>
You can do this like this
function selectIt(x) {
var elements = document.getElementsByClassName('item');
for (var i = 0; i < elements.length; i++) {
elements[i].style.backgroundColor = 'white';
}
x.style.backgroundColor = "red"
}
<div class="list">
<div class="item" onclick="selectIt(this)">item 1</div>
<div class="item" onclick="selectIt(this)">item 2</div>
<div class="item" onclick="selectIt(this)">item 3</div>
<div class="item" onclick="selectIt(this)">item 4</div>
<div class="item" onclick="selectIt(this)">item 5</div>
</div>
Basically first i have made background color of class item = white
then i have made background of "this" red
I am still getting to grips with jQuery and wondered if anyone had a suggestion for this?
Basically on click I want to show the div with the matching class, so if you click the btn with class '.project1' then it should show the content div with the same class of '.project1'.
I'm just stuck on how it would find this so any suggestions would be awesome :)
Thanks in advance.
Snippet:
$('div[class*="project"]').click(function (e) {
$(this).closest('.content').show();
});
.content {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="project1 btn">BTN 1</div>
<div class="project2 btn">BTN 2</div>
<div class="project3 btn">BTN 3</div>
<div class="project4 btn">BTN 4</div>
<div class="project1 content">CONTENT 1</div>
<div class="project2 content">CONTENT 2</div>
<div class="project3 content">CONTENT 3</div>
<div class="project4 content">CONTENT 4</div>
CodePen: https://codepen.io/nickelse/pen/mYrOdz?editors=1111
One option is to use data() to store arbitrary data associated with the matched elements or return the value at the named data store for the first element in the set of matched elements.
$('div[class*="project"]').click(function (e) {
var project = $(this).data("project"); //Get the data-project of the clicked element
$(".content.project" + project).toggle(); //Toggle the element with content and project class
});
.content {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="project1 btn" data-project="1">BTN 1</div> <!-- Add data-project on HTML-->
<div class="project2 btn" data-project="2">BTN 2</div>
<div class="project3 btn" data-project="3">BTN 3</div>
<div class="project4 btn" data-project="4">BTN 4</div>
<div class="project1 content" data-project="1">CONTENT 1</div>
<div class="project2 content" data-project="2">CONTENT 2</div>
<div class="project3 content" data-project="3">CONTENT 3</div>
<div class="project4 content" data-project="4">CONTENT 4</div>
You need to find the project number you clicked on.
You can do that by filtering the classes of the button you clicked on and extracting the number :
+[...this.classList].find(c => c.startsWith('project')).replace('project', '');
Then all you have to do is toggle the targeted project content :
$('.content.project'+project).toggle();
Here's a working example:
$('div[class^="project"]').on('click', function(){
const project = +[...this.classList].find(c => c.startsWith('project')).replace('project', '');
$('.content.project'+project).toggle();
});
.content {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="project1 btn">BTN 1</div>
<div class="project2 btn">BTN 2</div>
<div class="project3 btn">BTN 3</div>
<div class="project4 btn">BTN 4</div>
<div class="project1 content">CONTENT 1</div>
<div class="project2 content">CONTENT 2</div>
<div class="project3 content">CONTENT 3</div>
<div class="project4 content">CONTENT 4</div>
Toggling based on class matching is one of the harder thing to do in JQuery, however to achieve what you require you could do the following:
/* When a btn is clicked */
$('.btn').click(function(e) {
/* Extract the classes of this button element */
const classes = $(this).attr('class');
/* Parse the project class part of the classes string */
const projectClass = classes.match(/project\d+/)[0];
/* Construct a matcher for the projects corresponding
content and "toggle" the content's visiblity */
$('.content.' + projectClass).toggle();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div class="project1 btn">BTN 1</div>
<div class="project2 btn">BTN 2</div>
<div class="project3 btn">BTN 3</div>
<div class="project4 btn">BTN 4</div>
<div class="project1 content">CONTENT 1</div>
<div class="project2 content">CONTENT 2</div>
<div class="project3 content">CONTENT 3</div>
<div class="project4 content">CONTENT 4</div>
You can try to use regex to the class started with "project" and then show or hide it
$('.btn').click(function (e) {
var classArray = $(this).attr("class"),
re = /^project[0-9]+/ ,
className = re.exec(classArray)[0];
$('.content.'+ className).toggle();
});
$('.btn').click(function (e) {
var classArray = $(this).attr("class"),
re = /^project[0-9]+/ ,
className = re.exec(classArray)[0];
$('.content.'+ className).toggle();
});
.content {
display: none
}
.btn {
cursor:pointer
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="project1 btn">BTN 1</div>
<div class="project2 btn">BTN 2</div>
<div class="project3 btn">BTN 3</div>
<div class="project4 btn">BTN 4</div>
<div class="project1 content">CONTENT 1</div>
<div class="project2 content">CONTENT 2</div>

I want to insert html after a particular element but insertAdjacentHTML wont let me add a closing tag first.
If I do
elm.insertAdjacentHTML('afterend', '</div><section class="block">');
the expected result is
<element></element></div><section class="block">
the result it's returning
<element></element><section class="block"></div>
Is there a way around this?
Edit:
Basically what i'm trying to do is loop through each element and split them into two divs
<div class="column">
<div class="block">block 1</div>
<div class="block">block 2</div>
<div class="block">block 3</div>
<div class="block">block 4</div>
<div class="block">block 5</div>
<div class="block">block 6</div>
<div class="block">block 7</div>
<div class="block">block 8</div>
</div>
Expected result
<div class="column">
<div class="block">block 1</div>
<div class="block">block 2</div>
<div class="block">block 3</div>
<div class="block">block 4</div>
</div>
<div class="column">
<div class="block">block 5</div>
<div class="block">block 6</div>
<div class="block">block 7</div>
<div class="block">block 8</div>
</div>
JS
const blocks = document.querySelectorAll(".block");
let half = Math.ceil(blocks.length / 2 - 1);
blocks[half].insertAdjacentHTML('afterend', '</div><div class="column">');
If I get your requirement right, this is what you want to do:
elm.parentNode.insertAdjacentHTML('afterend', '<section class="block"></section>');
If the div is not the direct parent element, you might want to use Element.closest(selector) instead:
elm.closest('div.myDiv').insertAdjacentHTML('afterend', '<section class="block"></section>');
update
You have elaborated on your requirements further, this is how to do it in Javascript:
const blocks = [...document.querySelectorAll('.block')];
const middle = Math.ceil(blocks.length / 2 - 1);
const column = document.querySelector('.column');
const parent = document.querySelector('.parent');
const col1 = document.createElement('div');
col1.className = 'column';
const col2 = document.createElement('div');
col2.className = 'column';
blocks.forEach((block, index) => {
if (index <= middle) {
col1.appendChild(block)
} else {
col2.appendChild(block)
}
})
parent.removeChild(column)
parent.appendChild(col1);
parent.appendChild(col2);
.column+.column {
color: green;
}
<div class="parent">
<div class="column">
<div class="block">block 1</div>
<div class="block">block 2</div>
<div class="block">block 3</div>
<div class="block">block 4</div>
<div class="block">block 5</div>
<div class="block">block 6</div>
<div class="block">block 7</div>
<div class="block">block 8</div>
</div>
</div>
Resulting DOM:
I know this question is kind of weird but i am not able to find out this
For Example : there is some div with ids
HTML
<div id="test1">test 1</div>
<div id="test2">test 2</div>
<div id="test3">test 3</div>
<div id="test4">test 4</div>
<div id="test5">test 5</div>
<div id="test6">test 6</div>
and i want to toggle some specific div
like
test1, test4 and test6
so i have to do like this
$('#test1').toggle();
$('#test4').toggle();
$('#test6').toggle();
but i want to know is there any way to do that like
$('#test1', '#test4', '#test6').toggle();
I know it can be done if i just give same class on the div which i want to toggle.
but i want to know this for that reason i asked
Sure you can, simply comma separate your ID selector:
$('#test1, #test4, #test6').toggle();
$("#toggle").on("click", function(){
$('#test1, #test4, #test6').toggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="toggle">TOGGLE 1, 4, 6</button>
<div id="test1">test 1</div>
<div id="test2">test 2</div>
<div id="test3">test 3</div>
<div id="test4">test 4</div>
<div id="test5">test 5</div>
<div id="test6">test 6</div>
A much reusable code would allow you to toggle any desired elements without copy/pasting your JavaScript functions.
Here's an example where the desired selector to toggle is stored within the data-toggle attribute of the action element:
$("[data-toggle]").on("click", function(){
$(this.dataset.toggle).toggle();
});
.hidden{display:none;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button data-toggle="#test1,#test6">Toggle 1, 6</button>
<button data-toggle="#test3,#test4">Toggle 3, 4</button>
<div id="test1">test 1</div>
<div id="test2">test 2</div>
<div id="test3">test 3</div>
<div id="test4">test 4</div>
<div id="test5">test 5</div>
<div id="test6">test 6</div>
<button data-toggle=".info">Toggle .info</button>
