JS. How to Break selection/range into fragments per containing blocks and remove inline element formatting?

Lets say we have a div
<div id="my-div">
<p>Lorem ipsum dolor sit <strong>amet |consequat pharetra auctor </strong>condimentum lacus purus tortor habitasse molestie.</p>
<p>Auctor luctus lacus imperdiet <strong>pharetra| consequat</strong> egestas faucibus.</p>
</div>
And user selects a portion similar the one between "|".
function getSelectionPortion(){
const div = document.getElementById('my-div');
const selection = document.getSelection().getRangeAt(0).cloneContents(); // or extractContents();
return selection;
}
getSelectionPortion() will return the following:
<p><strong>consequat pharetra auctor </strong>condimentum lacus purus tortor habitasse molestie.</p>
<p>Auctor luctus lacus imperdiet <strong>pharetra</strong></p>
now we can get portions of the range by paragraphs, simply by e.g. fragment.querySelectorAll('p').
And if we extract the range contents and loop over each portion, we can take each strong inside each p and replace with its innerHTML
let blocks = getSelectionPortion().querySelectorAll('p');
for (let block of blocks){
let inlines = block.querySelectorAll('strong');
for (let inline of inlines){
inline.replaceWith(inline.innerHTML);
}
}
However, this outputs with additional paragraphs, because extracted fragment closes the paragraph tags. So we end up with
<div id="my-div">
<p>Lorem ipsum dolor sit <strong>amet</strong></p>
<p>consequat pharetra auctor condimentum lacus purus tortor habitasse molestie.</p>
<p>Auctor luctus lacus imperdiet pharetra</p>
<p><strong>consequat</strong> egestas faucibus.</p>
</div>
How do you remove the inline tag from the selection without creating additional block level elements with fragment? Is there a way to divide the range into peaces instead of its extract?

add value to existing class in jQuery

First of all, I have searched quite some hours to find this.. I presume it has an easy fix but I'm really new to jQuery and Javascript, so I'm here for your help.
The problem
I'm working with multiple divs and jQuery ToggleSlide(). I want the script to find the right div to open when I click the corresponding div.
For example, when I click the div 'hackandfly', I want it to open the div 'hackandfly-open'.
The code
$(document).ready(function() {
$('.project-open').hide();
$('.hackandfly, .scanergy, .connecting-food').click(function() {
$slidah = $(this);
$slidah.slideToggle();
$('div.project-open').not($slidah).slideUp();
});
});
HTML
<div class="content projects">
<h3>Projects</h3>
<div class="project project-big hackandfly">
<h3>Hack and Fly</h3>
</div>
<div class="hackandfly-open project-open" style="display: none;">
<img src="images/schiphol-logo.png" class="img-project-open"> Proin nec elit ac sapien facilisis ultrices. Integer pellentesque ex a luctus fringilla. Aenean in quam quam. Integer gravida quam eget mauris laoreet hendrerit. Vestibulum feugiat ipsum id.
<br>
<br>
Metus aliquet iaculis. Proin massa justo, maximus in tortor et, Proin massa justo, maximus in tortor et. In aliquam laoreet magna et iaculis. Vestibulum vel orci lobortis, elementum nulla eget, porta eros. Interdum et malesuada fames ac ante ipsum primis in faucibus.
<br>
<br>
Proin massa justo, maximus in tortor et, tincidunt efficitur nibh. Mauris vulputate euismod lorem, vel rutrum ipsum iaculis eu.
</div>
So what I'm looking for, is that when I push 'hackandfly' div, 'scanergy' div or the 'connecting-food' div, I want it to slideToggle the corresponding div that has -open behind it (I have 3 divs with info called hackandfly-open, scanergy-open, connecting-food-open).
I tried some things like:
$slidah = $(this).after('-open');
And some other stuff but it didn't work. Who can help me?
Cheers!

Use attr() like
$(document).ready(function() {
$('.project-open').hide();
$('.hackandfly, .scanergy, .connecting-food').click(function() {
$slidah = $($(this).attr('class')+'-open');
$slidah.slideToggle();
$('div.project-open').not($slidah).slideUp();
});
});
However, the above will fail if you have multiple classes.
A workaround would be to add data-* to the clicked elements like
<div class="hackandfly other-class" data-class-target="hackandfly-open"></div>
and then
$(document).ready(function() {
$('.project-open').hide();
$('.hackandfly, .scanergy, .connecting-food').click(function() {
$slidah = $('.'+$(this).attr('data-class-target'));
$slidah.slideToggle();
$('div.project-open').not($slidah).slideUp();
});
});

I would generate a unique click handler for each class. That way, you can store all the applicable class names in an array:
// Creates a new unique click function for each class name
function generateClickHandler(className) {
return function(e) {
// select the open class here
$slidah = $('.'+className+'-open');
$slidah.slideToggle();
$('div.project-open').not($slidah).slideUp();
};
}
// Iterate over all the class names and add a new function for each
var clsList = ["hackandfly", "scanergy", "connecting-food"];
$.each(clsList, function(className) {
$("."+className).click(generateClickHandler(className));
});

Use:
$('.hackandfly, .scanergy, .connecting-food').click(function() {
$slidah = $("."+$(this).attr('class')+"-open");
$slidah.slideToggle();
});

If you added a wrapper around each section like so:
<div class="content projects">
<h3>Projects</h3>
<div class="project-wrapper">
<div class="project project-big hackandfly">
<h3>Hack and Fly</h3>
</div>
<div class="hackandfly-open project-open" style="display: none;">
{...}
</div>
</div>
</div>
you could use parent and find to get the corresponding element as follows:
$('.hackandfly, .scanergy, .connecting-food').click(function() {
$(this).parent().find('.project-open').eq(0).slideToggle();
}

How to make next div open when previous closes using jquery?

I have tried so far and made some pretty long code. This seems okay when one is having less then five or ten divs. But what if these are to be implemented on 20 or more than that....?
Can there be any compact form of the code I have tried to write.
( I am some novice in jquery to build complex function but try to write these sorts. )
Any one can help..?
Fiddle is here : http://jsfiddle.net/Ud574/27/
The Code is as follows.
$(document).ready(function(){
$('.button').click(function() {
$('.content').hide(500)
$('.headOne').addClass("classRight");
$('.content1').show(500)
});
$('.button1').click(function() {
$('.content1').hide(500)
$('.headTwo').addClass("classRight");
$('.content2').show(500)
});
$('.button2').click(function() {
$('.content2').hide(500)
$('.headThree').addClass("classRight");

If I understand correctly, you need something similar to the Accordion control.
Have a look at jQuery UI Accordion on the following url: http://jqueryui.com/accordion/
Does this sound reasonable to you?

I played with your code a bit and simplified it a lot, using built-in jQuery functions. Here's the HTML:
<div class="closable"> Employee personal record
<div class="content">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum bibendum ullamcorper convallis.
</div></div>
<div class="closable"> Employee personal record
<div class="content">Pellentesque felis elit, tempor vitae dapibus felis eu erat. <br />
</div></div>
<div class="closable"> Employee personal record
<div class="content">Aliquam eget porta. Maecenas viverra mi id lectus pellentesque viverra</div></div>
<div class="closable"> Employee personal record
<div class="content">Aliquam a magna ac justo accumsan porttitor.</div></div>
<div class="button4">Go To Previous section </div></div>
Here's the Javascript:
$(document).ready(function(){
$('.content').first().show();
$('.closable').click(function() {
if ($(this).find('div').first().is(':visible')){
$(this).find('div').first().hide();
$(this).next().find('div').first().show();
}else{
$(this).find('div').first().show();
}
});
});
And the CSS:
.content{display:block;}
.content{font-weight: normal; border: 0;display:none;}
.closable{font-weight:bold;border:1px solid #CCC;}
Hope this helps!

jQuery popup box only show once in foreach loop

First, let me explain the purpose of the popup. I have a list from a database of products, in a foreach loop.
Now I added code so that when you click the product, it opens a new box and shows content about this product. But for some reason, it only works on the first product.
I will post the code here, since I am very bad at jQuery/Javascript.
Here is the jquery script:
;(function($) {
// DOM Ready
$(function() {
// Binding a click event
// From jQuery v.1.7.0 use .on() instead of .bind()
$('#wiki-button').on('click', function(e) {
// Prevents the default action to be triggered.
e.preventDefault();
// Triggering bPopup when click event is fired
$('#wiki-content').bPopup();
});
});
})(jQuery);
A snippet from the loop:
foreach ($getTheOffers as $getTheOffer ) { ?>
<div id="wiki-content">
<div class="box9">
<h1>Sample Box</h1>
<img src="imageurl">
<p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam luctus consectetur dolor a porttitor. Curabitur id sem sed ante fringilla pulvinar et id lectus. Nullam justo ipsum, hendrerit ut commodo nec, pellentesque nec erat. Pellentesque pharetra.</p><br/>
</div>
</div>
<?php } ?>
If you need to see more code, I will post it in pastebin.

Use class instead of id
So, in your HTML
<div class="wiki-content">
And in your jQuery
$('.wiki-button').on('click', function(e) {
// Prevents the default action to be triggered.
e.preventDefault();
// Triggering bPopup when click event is fired
$(this).bPopup();
}

Change id to class. Id should be unique otherwise only the first element will be select
;(function($) {
// DOM Ready
$(function() {
// Binding a click event
// From jQuery v.1.7.0 use .on() instead of .bind()
$('.wiki-button').on('click', function(e) {
//___^_____________
// Prevents the default action to be triggered.
e.preventDefault();
// Triggering bPopup when click event is fired
$('.wiki-content').bPopup();
// ___^___________
});
});
})(jQuery);
foreach ($getTheOffers as $getTheOffer ) { ?>
<div class="wiki-content">
<!-- _____^____________________-->
<div class="box9">
<h1>Sample Box</h1>
<img src="imageurl">
<p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam luctus consectetur dolor a porttitor. Curabitur id sem sed ante fringilla pulvinar et id lectus. Nullam justo ipsum, hendrerit ut commodo nec, pellentesque nec erat. Pellentesque pharetra.</p><br/>
</div>
</div>
<?php } ?>

Problem:
You have repeating ID's. The ID selector only expects one result, and gives you one, the first element. Hence, only the first is working.
Solution:
Use classes! Give a common class to your repeating elements and target that.

jQuery UI accordion that keeps multiple sections open?

I may be an idiot, but how do you keep multiple sections in jQuery UI's accordion open? The demos all have only one open at a time... I'm looking for a collapseable menu type system.

Pretty simple:
<script type="text/javascript">
(function($) {
$(function() {
$("#accordion > div").accordion({ header: "h3", collapsible: true });
})
})(jQuery);
</script>
<div id="accordion">
<div>
<h3>First</h3>
<div>Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.</div>
</div>
<div>
<h3>Second</h3>
<div>Phasellus mattis tincidunt nibh.</div>
</div>
<div>
<h3>Third</h3>
<div>Nam dui erat, auctor a, dignissim quis.</div>
</div>
</div>

This was originally discussed in the jQuery UI documentation for Accordion:
NOTE: If you want multiple sections
open at once, don't use an accordion
An accordion doesn't allow more than
one content panel to be open at the
same time, and it takes a lot of
effort to do that. If you are looking
for a widget that allows more than one
content panel to be open, don't use
this. Usually it can be written with a
few lines of jQuery instead, something
like this:
jQuery(document).ready(function(){
$('.accordion .head').click(function() {
$(this).next().toggle();
return false;
}).next().hide();
});
Or animated:
jQuery(document).ready(function(){
$('.accordion .head').click(function() {
$(this).next().toggle('slow');
return false;
}).next().hide();
});
"I may be an idiot" - You're not an idiot if you don't read the documentation, but if you're having problems, it usually speeds up finding a solution.

Posted this in a similar thread, but thought it might be relevant here as well.
Achieving this with a single instance of jQuery-UI Accordion
As others have noted, the Accordion widget does not have an API option to do this directly. However, if for some reason you must use the widget (e.g. you're maintaining an existing system), it is possible to achieve this by using the beforeActivate event handler option to subvert and emulate the default behavior of the widget.
For example:
$('#accordion').accordion({
collapsible:true,
beforeActivate: function(event, ui) {
// The accordion believes a panel is being opened
if (ui.newHeader[0]) {
var currHeader = ui.newHeader;
var currContent = currHeader.next('.ui-accordion-content');
// The accordion believes a panel is being closed
} else {
var currHeader = ui.oldHeader;
var currContent = currHeader.next('.ui-accordion-content');
}
// Since we've changed the default behavior, this detects the actual status
var isPanelSelected = currHeader.attr('aria-selected') == 'true';
// Toggle the panel's header
currHeader.toggleClass('ui-corner-all',isPanelSelected).toggleClass('accordion-header-active ui-state-active ui-corner-top',!isPanelSelected).attr('aria-selected',((!isPanelSelected).toString()));
// Toggle the panel's icon
currHeader.children('.ui-icon').toggleClass('ui-icon-triangle-1-e',isPanelSelected).toggleClass('ui-icon-triangle-1-s',!isPanelSelected);
// Toggle the panel's content
currContent.toggleClass('accordion-content-active',!isPanelSelected)
if (isPanelSelected) { currContent.slideUp(); } else { currContent.slideDown(); }
return false; // Cancels the default action
}
});
See a jsFiddle demo

Or even simpler?
<div class="accordion">
<h3>First</h3>
<div>Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.</div>
</div>
<div class="accordion">
<h3>Second</h3>
<div>Phasellus mattis tincidunt nibh.</div>
</div>
<div class="accordion">
<h3>Third</h3>
<div>Nam dui erat, auctor a, dignissim quis.</div>
</div>
<script type="text/javascript">
$(".accordion").accordion({ collapsible: true, active: false });
</script>

I have done a jQuery plugin that has the same look of jQuery UI Accordion and can keep all tabs\sections open
you can find it here
http://anasnakawa.wordpress.com/2011/01/25/jquery-ui-multi-open-accordion/
works with the same markup
<div id="multiOpenAccordion">
<h3>tab 1</h3>
<div>Lorem ipsum dolor sit amet</div>
<h3>tab 2</h3>
<div>Lorem ipsum dolor sit amet</div>
</div>
Javascript code
$(function(){
$('#multiOpenAccordion').multiAccordion();
// you can use a number or an array with active option to specify which tabs to be opened by default:
$('#multiOpenAccordion').multiAccordion({ active: 1 });
// OR
$('#multiOpenAccordion').multiAccordion({ active: [1, 2, 3] });
$('#multiOpenAccordion').multiAccordion({ active: false }); // no opened tabs
});
UPDATE:
the plugin has been updated to support default active tabs option
UPDATE:
This plugin is now deprecated.

Simple: active the accordion to a class, and then create divs with this, like multiples instances of accordion.
Like this:
JS
$(function() {
$( ".accordion" ).accordion({
collapsible: true,
clearStyle: true,
active: false,
})
});
HTML
<div class="accordion">
<h3>Title</h3>
<p>lorem</p>
</div>
<div class="accordion">
<h3>Title</h3>
<p>lorem</p>
</div>
<div class="accordion">
<h3>Title</h3>
<p>lorem</p>
</div>

Actually was searching the internet for a solution to this for a while. And the accepted answer gives the good "by the book" answer. But I didn't want to accept that so I kept searching and found this:
http://jsbin.com/eqape/1601/edit - Live Example
This example pulls in the proper styles and adds the functionality requested at the same time, complete with space to write add your own functionality on each header click. Also allows multiple divs to be in between the "h3"s.
$("#notaccordion").addClass("ui-accordion ui-accordion-icons ui-widget ui-helper-reset")
.find("h3")
.addClass("ui-accordion-header ui-helper-reset ui-state-default ui-corner-top ui-corner-bottom")
.hover(function() { $(this).toggleClass("ui-state-hover"); })
.prepend('<span class="ui-icon ui-icon-triangle-1-e"></span>')
.click(function() {
$(this).find("> .ui-icon").toggleClass("ui-icon-triangle-1-e ui-icon-triangle-1-s").end()
.next().toggleClass("ui-accordion-content-active").slideToggle();
return false;
})
.next()
.addClass("ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom")
.hide();

I found a tricky solution. Lets call the same function twice but with different id.
JQuery Code
$(function() {
$( "#accordion1" ).accordion({
collapsible: true, active: false, heightStyle: "content"
});
$( "#accordion2" ).accordion({
collapsible: true, active: false, heightStyle: "content"
});
});
HTML Code
<div id="accordion1">
<h3>Section 1</h3>
<div>Section one Text</div>
</div>
<div id="accordion2">
<h3>Section 2</h3>
<div>Section two Text</div>
</div>

Simple, create multiple accordian div each representating one anchor tag like:
<div>
<div class="accordion">
First heading
</div>
<div class="accordion">
First heading
</div>
</div>
It adds up some markup. But works like a pro...

Just call each section of the accordion as its own accordion. active: n will be 0 for the first one( so it will display) and 1, 2, 3, 4, etc for the rest. Since each one is it's own accordion, they will all have only 1 section, and the rest will be collapsed to start.
$('.accordian').each(function(n, el) {
$(el).accordion({
heightStyle: 'content',
collapsible: true,
active: n
});
});

Even simpler, have it labeled in each li tag's class attribute and have jquery to loop through each li to initialize the accordion.

Without jQuery-UI accordion, one can simply do this:
<div class="section">
<div class="section-title">
Section 1
</div>
<div class="section-content">
Section 1 Content: Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.
</div>
</div>
<div class="section">
<div class="section-title">
Section 2
</div>
<div class="section-content">
Section 2 Content: Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.
</div>
</div>
And js
$( ".section-title" ).click(function() {
$(this).parent().find( ".section-content" ).slideToggle();
});
https://jsfiddle.net/gayan_dasanayake/6ogxL7nm/

open jquery-ui-*.js

} else {
var toShow = clicked.next();
var toHide = $();

oldPanel: toHide,
newHeader: clicked,
newPanel: toShow
};
before active.removeClass( "ui-accordion-header-active ui-state-active" );
add if (typeof(active) !== 'undefined') { and closing }

I know this question specifically asks for jQuery UI.
I always find myself exploring jQuery UI Accordion and then remembering that I can just use the native DETAILS and SUMMARY elements (except for IE11) to implement essentially the same type of feature: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details
Just a reminder in case you forget as often as I do.
