I'm using javascript to build a list of results. I have a for-loop that iterates over some data and creates a mydata div, and adds that to the results div. Let's pretend it looks something like this:
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
...
<div class="mydata">data 20</div>
</div>
What I want to do is only display 5 results at a time, and should the user wish to see more, they can click a show next 5 or show more button (or something similar). Any ideas?
Just to clarify, every time the user clicks "show more" I want to 'unhide' the next 5 elements, not ALL the remaining elements. So each click reveals more elements until all are displayed.
You can use the gt() and lt() selectors along with :visible pretty well here.
The following will show the next 5 results on clicking and removes the link once all items are visible.
$('.mydata:gt(4)').hide().last().after(
$('<a />').attr('href','#').text('Show more').click(function(){
var a = this;
$('.mydata:not(:visible):lt(5)').fadeIn(function(){
if ($('.mydata:not(:visible)').length == 0) $(a).remove();
}); return false;
})
);
working example: http://jsfiddle.net/niklasvh/nTv7D/
Regardless of what other people are suggesting here, I would not hide the elements using CSS, but do it in JS instead, because if a user has JS disabled and you hide the elements using CSS, he won't get them visible. However, if he has JS disabled, they will never get hidden, nor will that button appear etc, so it has a full noscript fallback in place + search engines don't like hidden content (but they won't know its hidden if you do it on DOM load).
My solution is here: jsFiddle.
You can put this link somewhere:
show more
and use the following code:
var limit = 5;
var per_page = 5;
jQuery('#results > div.mydata:gt('+(limit-1)+')').hide();
if (jQuery('#results > div.mydata').length <= limit) {
jQuery('#results-show-more').hide();
};
jQuery('#results-show-more').bind('click', function(event){
event.preventDefault();
limit += per_page;
jQuery('#results > div.mydata:lt('+(limit)+')').show();
if (jQuery('#results > div.mydata').length <= limit) {
jQuery(this).hide();
}
});
where limit is your current number of results displayed and per_page is number of results shown with each click on "show more". The link disappears if all the results are displayed. See how it works on jsFiddle.
You can create a CSS class like:
.hiddenData { display: none }
and attach it to any quantity of divs that exceeds 5.
After that make handlers for adding/deleting this class from the needed quantity of divs.
jQuery for class removing:
$(".hiddenData").removeClass("hiddenData")
Create a class with something like:
.hidden_class{
display: none;
}
Add this class to all the mydata div's that you dont want seen.
when the user click the button, remove it from the next 5 div's.
repeat everytime the user clicks the "read more" button
This should work...Let me know how it goes
<script type="text/javascript">
function ShowHide(id) { $("#" + id).toggle(); }
</script>
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
<div class="mydata">data 3</div>
<div class="mydata">data 4</div>
<div class="mydata">data 5</div>
<div style="clear:both" onclick="ShowHide('grp6')">More</div>
<div id="grp6" style="display:none">
<div class="mydata">data 6</div>
<div class="mydata">data 7</div>
<div class="mydata">data 8</div>
<div class="mydata">data 9</div>
<div class="mydata">data 10</div>
</div>
<div style="clear:both" onclick="ShowHide('grp11')">More</div>
<div id="grp11" style="display:none">
<div class="mydata">data 11</div>
<div class="mydata">data 12</div>
<div class="mydata">data 13</div>
<div class="mydata">data 14</div>
<div class="mydata">data 15</div>
</div>
</div>
In your forloop, you also have to add these divs hidden container
<div style="clear:both" onclick="ShowHide('grp6')">More</div>
<div id="grp6" style="display:none">
You get the idea.
Here you have:
<style>
/*This hides all items initially*/
.mydata{
display: none;
}
</style>
Now the script
<script>
var currentPage = 1; //Global var that stores the current page
var itemsPerPage = 5;
//This function shows a specific 'page'
function showPage(page){
$("#results .mydata").each(function(i, elem){
if(i >= (page-1)*itemsPerPage && i < page*itemsPerPage) //If item is in page, show it
$(this).show();
else
$(this).hide();
});
$("#currentPage").text(currentPage);
}
$(document).ready(function(){
showPage(currentPage);
$("#next").click(function(){
showPage(++currentPage);
});
$("#prev").click(function(){
showPage(--currentPage);
});
});
</script>
And a sample html:
<div id="results">
<div class="mydata">data 1</div>
<div class="mydata">data 2</div>
<div class="mydata">data 3</div>
<div class="mydata">data 4</div>
<div class="mydata">data 5</div>
<div class="mydata">data 6</div>
<div class="mydata">data 7</div>
<div class="mydata">data 8</div>
<div class="mydata">data 9</div>
<div class="mydata">data 10</div>
<div class="mydata">data 11</div>
<div class="mydata">data 12</div>
</div>
Previous
<span id="currentPage"></span>
Next
The only thing remaining is to validate fot not going to a page lower than 1 and higher than the total. But that will be easy.
EDIT: Here you have it running: http://jsfiddle.net/U8Q4Z/
Hope this helps. Cheers.

I have 2 identical div blocks on the page, inside of which there are several div blocks with different texts. It looks something like this:
<div class="dynamic_titles">
<div class="dynamic_title active">text 1</div>
<div class="dynamic_title inactive">text 2</div>
<div class="dynamic_title inactive">text 3</div>
<div class="dynamic_title inactive">text 4</div>
<div class="dynamic_title inactive">text 5</div>
</div>
<div class="dynamic_titles">
<div class="dynamic_title active">text 6</div>
<div class="dynamic_title inactive">text 7</div>
<div class="dynamic_title inactive">text 8</div>
<div class="dynamic_title inactive">text 9</div>
<div class="dynamic_title inactive">text 10</div>
</div>
I need to change classes from inactive to active in each dynamic_title block in turn. That is, the next one takes active, and the previous one with active in inactive and so on in a circle.
When I have one dynamic_titles block, everything works fine, but 2 interfere with each other, break. I'm trying not to make 2 functions for each block separately, I want to make one universal one that would be applied to each block separately.
Now I have such a code, but it does not work as expected. It runs once and goes no further. If done without .each, it works, but again not as expected and eventually breaks. What is my mistake?
$('.dynamic_titles').each(function () {
var index = 1,
max = $(this).find('.dynamic_title').length;
function setActiveHeadline() {
setTimeout(function () {
$(this).find('.active').removeClass('active').addClass('inactive');
index++;
if (index > max) {
index = 1;
}
$(this).find('.dynamic_title:nth-of-type(' + index + ')').addClass('active').removeClass('inactive');
setActiveHeadline();
}, 3000);
}
setActiveHeadline();
widthTitle = $(this).find('.dynamic_title.active').width();
$(this).css({
'width': widthTitle,
});
function setWidthHeadlines() {
setTimeout(function () {
widthTitle = $(this).find('.dynamic_title.active').width();
$(this).css({
'width': widthTitle,
});
setWidthHeadlines();
}, 3000);
}
setWidthHeadlines();
})
Thank you for your help!
I think you could simplify this into one function that uses setInterval, please see the following snippet:
$(function(){
//use setInterval to continue the changes
setInterval(() => {
//iterate the blocks
$('div.dynamic_titles').each(function() {
//get the children
const $children = $(this).find('div.dynamic_title');
//get the number of children
const numofchildren = $children.length;
//index for switching active in children
let activeindex = 0;
//iterate children to find the active one
$children.each(function(i, el) {
//if active, remove active and add inactive classNames
//store the index
//break the each loop
if($(el).hasClass('active')){
$(el).removeClass('active').addClass('inactive');
activeindex = i + 1;
return false;
}
});
//if index has reached the last child, reset to zero
if(activeindex > numofchildren - 1){
activeindex = 0;
}
//set the next child to active and remove inactive className
$children[activeindex].classList.add('active');
$children[activeindex].classList.remove('inactive');
});
}, 3000);
})
.active {
color:green;
}
.inactive {
color:grey;
}
<div class="dynamic_titles">
<div class="dynamic_title active">text 1</div>
<div class="dynamic_title inactive">text 2</div>
<div class="dynamic_title inactive">text 3</div>
<div class="dynamic_title inactive">text 4</div>
<div class="dynamic_title inactive">text 5</div>
</div>
<div class="dynamic_titles">
<div class="dynamic_title active">text 6</div>
<div class="dynamic_title inactive">text 7</div>
<div class="dynamic_title inactive">text 8</div>
<div class="dynamic_title inactive">text 9</div>
<div class="dynamic_title inactive">text 10</div>
</div>

Well, I have n elements with the class "class_one"
and certain other elements with the class "class_two".
These elements are nested and in some cases there are other elements in that nest, what I need is to select the next element with a specific class.
let class_one = document.querySelectorAll('.class_one');
class_one.forEach(element => {
element.addEventListener('click',()=>{
console.log("From this element, the next one containing the class class_two");
})
});
<div class="class_one">
click 1
</div>
<div class="class_two">elemento 1</div>
<div class="class_one">
click 2
</div>
<div class="class_four"></div>
<div class="class_two">elemento 2</div>
<div class="class_one">
click 3
</div>
<div class="class_six"></div>
<div class="class_two">elemento 3</div>
<div class="class_one">
click 4
</div>
<div class="class_five">click 5</div>
<div class="class_two">elemento 4</div>
<div class="class_one">
click 6
</div>
<div class="class_two"></div>
Personally, I would like an answer without using Jquery, but all are welcome.
I have the next code:
<div class="components_container">
<div class="first_group">Element 1</div>
<div class="first_group">Element 2</div>
<div class="first_group">Element 3</div>
<div class="second_group">Element 4</div>
<div class="second_group">Element 5</div>
<div class="second_group">Element 6</div>
</div>
And I would like to wrap both groups in different div tags, like this:
<div class="components_container">
<div class="group1">
<div class="first_group">Element 1</div>
<div class="first_group">Element 2</div>
<div class="first_group">Element 3</div>
</div>
<div class="group2">
<div class="second_group">Element 4</div>
<div class="second_group">Element 5</div>
<div class="second_group">Element 6</div>
</div>
</div>
To do what you are trying to accomplish, you can do this in pure javascript:
Get a reference to the container (this code implies that you have only one element with that class):
var container = document.querySelector(".components_container");
Create the two external divs, add the classes and append them to the container:
var first_cont = document.createElement("div");
var second_cont = document.createElement("div");
first_cont.classList.add("group1");
second_cont.classList.add("group2");
container.appendChild(first_cont);
container.appendChild(second_cont);
Get the divs with a specific class and change their parent (remove child / append child):
var first_elements = container.querySelectorAll(".first_group");
var second_elements = container.querySelectorAll(".second_group");
for (el of first_elements) {
container.removeChild(el);
first_cont.appendChild(el);
}
for (el of second_elements) {
container.removeChild(el);
second_cont.appendChild(el);
}
This will do what you want, but please, next time try to add some more information, like some context, the steps that you tried or where are you finding difficulties :)
I have managed to toggle a div with different links. But when i'm trying to make more boxes which the same it doesn't work anymore.
Imagine I have like 10 entries - all separated divs 'entry'
<div class="entry" id="1">
where i want to separately hide and show content with multiple links.
My Question is, I'm trying to fix this since 5 hours, but which one div entry its working, with more than one it is not working.
I tried to use
$(".entry").each(function() {
Here is my code:
$(document).ready(function() {
$(".entry").each(function() {
var b4c = $('.lower_menu').html(); // content of box 4 so that we cn refer to it later
$(".menu1,.menu2,.menu3").click(function() {
var active_content = $(".lower_menu").data('content');
var cls = $(this).attr('class');
if (active_content == '') {
$(".lower_menu").html($("." + cls + '_CONTENT').html())
$(".lower_menu").data('content', cls);
} else {
if (active_content == cls) {
$('.lower_menu').html(b4c).data('content', '');
} else {
$(".lower_menu").html($("." + cls + '_CONTENT').html())
$(".lower_menu").data('content', cls);
}
}
});
});
});
.menu1 {height:40px; background-color:red;}
.menu2 {height:40px; background-color:green;}
.menu3 {height:40px; background-color:blue;}
.menu1_CONTENT {display:none; background-color:red;}
.menu2_CONTENT {display:none; background-color:green;}
.menu3_CONTENT {display:none; background-color:blue;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="entry">
<div class="menu1">
<span id="arrow_prod" class="glyphicon glyphicon-chevron-down arrow"></span> Heading 1
</div>
<div class="menu2">BOX 2</div>
<div class="menu3">BOX 3</div>
<!-- data-content is to check do we have content or which boxes's content do we hv now -->
<div class="lower_menu" data-content=""></div>
<div class="menu1_CONTENT">CONTENT FOR BOX 1</div>
<div class="menu2_CONTENT">CONTENT FOR BOX 2</div>
<div class="menu3_CONTENT">CONTENT FOR BOX 3</div>
</div>
<div class="entry">
<div class="menu1">BOX 1</div>
<div class="menu2">BOX 2</div>
<div class="menu3">BOX 3</div>
<!-- data-content is to check do we have content or which boxes's content do we hv now -->
<div class="lower_menu" data-content=""></div>
<div class="menu1_CONTENT">CONTENT FOR BOX 1</div>
<div class="menu2_CONTENT">CONTENT FOR BOX 2</div>
<div class="menu3_CONTENT">CONTENT FOR BOX 3</div>
</div>
... and a JSFiddle
it's a official bug of the jquery! We found one guys ! YEEEHAA
Lets say I have 100 divs and I want to show 5 divs each time.
onclick - I'm loading 5 more.
Any idea how to check if I reached the last div?
<div id="results">1</div>
<div id="results">2</div>
<div id="results">3</div>
<div id="results">4</div>
<div id="results">100</div>
$(function () {
$("results").slice(0, 5).show();
$("#moreresults").on('click', function(e){
e.preventDefault();
$("div:hidden").slice(0, 5).slideDown();
});
});

First of all the id attribute should be unique in the same document, so use common classes instead, e.g :
<div class="results">1</div>
<div class="results">2</div>
<div class="results">3</div>
<div class="results">4</div>
...
You could use index's with the help of the jQuery selectors lt() and gt(), check the working example below.
Hope this helps.
$(function () {
var number = 5;
var count = $('.results').length;
//Show just 5 first and hide the rest
$(".results:gt("+(number-1)+")").hide();
//Attach the click event
$("#moreresults").on('click', function(e){
e.preventDefault();
//Increment the 'number'
number = number+5;
//Show 'number' of element
$(".results:lt("+number+")").slideDown();
//Check if all divs are loaded
if( number >= count ){
console.log('All the divs are loaded');
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="results">1</div>

You can check to see if the last div is visible
if($('div:last').is(":visible")) {
//do things here
}
I made an working example for you here
First you have to use class not id on the 'results', and use $(".results:lt(5)")
Using last() and is():
var $results = $('.results');
$results.slice(5).hide();
$('#moreresults').click(function(e){
e.preventDefault();
var $nextResults = $results.filter(':hidden').slice(0,5).slideDown()
if( $nextResults.last().is( $results.last() ) ){
$(this).hide();
console.log('Last one')
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="results">Item 1</div>
<div class="results">Item 2</div>
<div class="results">Item 3</div>
<div class="results">Item 4</div>
<div class="results">Item 5</div>
<div class="results">Item 6</div>
<div class="results">Item 7</div>
<div class="results">Item 8</div>
