CKEditor 5-insert html and move the caret outside it

i have a button outside ckeditor, when clicked i want to insert a span element at caret position, this is what i have so far:
var el = document.querySelector('#editor');
ClassicEditor.create(el, {
licenseKey: ''
}).then( editor => {
appConfigs.editor = editor; //storing the editor for later usage
}).catch( error => {
//...
});
when the button is clicked i do:
function clickHandler(){
var editor = appConfigs.editor;
editor.model.change( writer => {
var html = '<span class="special-class-name" data-name="something">special word or button</span>';
var viewFragment = editor.data.processor.toView(html);
var modelFragment = editor.data.toModel(viewFragment);
var insertPosition = editor.model.document.selection.getFirstPosition();
editor.model.insertContent(modelFragment, insertPosition);
});
}
the code have the following issues:
1)the inserted span get stripped off all its attributes(class, data-name) which i want to preserve.
2)the editing caret doesn't go back automatically to the editor when the button clicked.
3)when i click the editor to restore caret and start typing, i noticed it edits the text inside inserted span, i want inserted span to be untouched and any further typing goes after it.
i will be so grateful if anyone could help me with those issues.

Create div scrollable elements according to the number of elements in an String array

I'm quiet new above all on Javascript technology. I want to create various div according to the number of string into an array of checked checkboxes but after my code it only displays one div every time... I must go through a jquery dialog to display it !
My JSP
<div style="overflow: scroll;" id="listCurrentContact"></div>
My listContact.js
varPopup = $('#dialogMultiplesDeleteConfirmation').dialog({
resizable : false,
modal : true,
autoOpen : false,
width : 500,
open: function(){
var SuppressCheckboxItems = [];
// I put into an array the different value of checked checkboxes
$("input:checkbox[id=suppressCheckbox]:checked").each(function() {
SuppressCheckboxItems.push($(this).val());
});
var z = document.createElement('div');
// I suppress the ',' between each element
var test = SuppressCheckboxItems.toString();
var tab = test.split(",");
for(var i = 0; i < tab.length; i++){
z.innerHTML = tab[i];
$('#listCurrentContact').html(z);
}

Have you tried using .append instead of .html while concatenating your checkboxes to #listCurrentContact.
You can refer this document: https://www.w3schools.com/jquery/html_html.asp to see that .html() replaces the previous content with the new content whereas what you are trying to achieve here is appending the entire array of values to the div. Look at how .append() works in this link : https://www.javascripttutorial.net/javascript-dom/javascript-append/. Just to give you a brief overview, when you write a .append() on any element, it doesnot replace the previous content with the new content but instead attaches/concatenates the new content after the previous content.

You should use $('#listCurrentContact').append(z);

Thanks to SaloniMishra Ive found the good answer. It just needed to change the .html() to .append() but with that if the customer just quit the jquery dialog and retry the previous elements stayed in the div so you need to clean every elements before to relaunch the function with the function removeChild()! Thanks all !
open : function() {
var SuppressCheckboxItems = [];
const currentDiv = document.getElementById('listCurrentContact');
while (currentDiv.firstChild) {
currentDiv.removeChild(currentDiv.lastChild);
}
$("input:checkbox[id=suppressCheckbox]:checked").each(function() {
var z = document.createElement('div');
z.innerHTML = $(this).attr("name");
$("#listCurrentContact").append(z);
});

Storing variable via .text() isn't uptodate

I have <span> tags in a div that is removed when user clicks on them. Works fine.
I want to store the .text() inside that div in a variable. The problem is that the updated text doesn't get stored.
Click on a word to remove it in this jsFiddle.
As you can see, the content variable returns the old text, not the new revised one.
How can I store a variable with the updated text?
jQuery:
jQuery(document).ready(function() {
jQuery(document).on("mousedown", ".hello span", function() {
// don't add full stop at the end of sentence if it already ends with
var endChars = [".", "?", "!"];
jQuery(this).fadeOut(function(){
var parentObj = jQuery(this).parent();
jQuery(this).remove();
var text = parentObj.find("span").first().html();
parentObj.find("span").first().html(ta_capitalizeFirstLetter(text));
text = parentObj.find("span").last().html();
if ( endChars.indexOf(text.slice(-1)) == -1 )
{
parentObj.find("span").last().html(text+".");
}
});
var content = jQuery(this).parent().parent().find('.hello').text();
alert(content);
});
});

The code to get the new text should be moved inside the fadeOut callback. Once the animation is completed and element is removed, then the innerText of the parent element will be updated. At this time, the updated content should be read from the DOM.
Demo
// Cache the element
var $el = jQuery(this).parent().parent().find('.hello');
jQuery(this).fadeOut(function () {
jQuery(this).remove();
// Irrelevant code removed from here
...
var content = $el.text();
alert(content);
});
Here's another simple demo with minimal code that'll help to understand the code better.
Demo

I tried to debug your jsfiddle in chrome, and it looks like the priority of your code is like this:
declare on this event - jQuery(this).fadeOut(function(){
get the the current data of the div var content = jQuery(this).parent().parent().find('.hello').text();.
alert your data without changes.
calling the funcntion of fadeout
I think all you have to do is to call your alert and 2 from your anonymous function of fadeout

Just put your alert inside the callback:
jQuery(this).fadeOut(function(){
var parentObj = jQuery(this).parent();
jQuery(this).remove();
var text = parentObj.find("span").first().html();
parentObj.find("span").first().html(ta_capitalizeFirstLetter(text));
text = parentObj.find("span").last().html();
if ( endChars.indexOf(text.slice(-1)) == -1 ) {
parentObj.find("span").last().html(text+".");
var content = parentObj.parent().find('.hello').text();
alert(content);
}
});

Using Javascript to hide text shown on currency switch

I'd like to use Javascript (on page load) to remove the wording 'Choose a currency to display the price:'.
Leaving just the currency icons in the box (Div id = currency-switch).
How can I do this?
Page url: http://www.workbooks.com/pricing-page
Image example:

You can remove this text with for example:
window.onload = function(){
var el = document.getElementById("currency-switch");
var child = el.childNodes[0];
el.removeChild(child);
};

If you want to keep it stupid simple just add an span around the text and give it an id like "currency_text".
Then you only need this code:
var elem = document.getElementByid("currency_text");
elem.remove();

Try
$(document).ready(function() {
var currencyDiv = $('#currency-switch');
currencyDiv.innerHTML(currencyDiv.innerHTML().replace("Choose a currency to display the price:", ""));
}
This will remove the text as soon as the DOM is ready.

Please see below which will just remove the text:
This will trigger on page load
<script>
// self executing function here
(function() {
var selected_div = document.getElementById('currency-switch');
var text_to_change = selected_div.childNodes[0];
text_to_change.nodeValue = '';
})();
</script>

Since it's a text node, you could do the following in jQuery. This will be triggered on DOM ready.
$(function() {
jQuery("#currency-switch").contents()
.filter(function() {
return this.nodeType === 3;
}).remove();
});

You can use this code:
var requiredContent = document.getElementById('currency-switch').innerHTML.split(':')[1];
document.getElementById('currency-switch').innerHTML = requiredContent;
See it working here: https://jsfiddle.net/eg4hpg4z/
However, it is not very clean, but should work, if you cant directly modify the html.
A better solution would be to modify your code to move the text content within a span and show hide the text like so:
HTML:
<div id="currency-switch">
<span class="currency-label">Choose a currency to display the price: </span>
<span class="gb-background"><span class="GB"> £ </span></span><span class="es-background"><span class="ES"> € </span></span><span class="au-background"><span class="AU"> $ </span></span></div>
Javascript:
document.getElementsByClassName('currency-label')[0].style.display = 'none';

Append HTML Tag Into Codemirror and Center Cursor Location

Fiddle - http://liveweave.com/kzBlq3
I'm trying to add custom html tags into CodeMirror and focus the cursor into the center of these tags.
Here's an example of how it'd be done for a textarea.
// Mirror Codemirror Code to Textarea
$(".code").val( editor.getValue() ).on('keyup change', function() {
editor.setValue( $(this).val() );
});
// Add center code
$(".bold").click(function() {
// For a regular textarea & center cursor
var start = $('.code').get(0).selectionStart;
$('.code').val($('.code').val().substring(0, start) + "<strong></strong>" + $('.code').val().substring($('.code').get(0).selectionEnd));
$('.code').get(0).selectionStart = $('.code').get(0).selectionEnd = start + 8;
$('.code').focus();
return false;
});
The lines and locations will always be different so I have to grab it's location first before I add and move it aside the added characters as I did with the textarea demo.
However I don't want to use a blank textarea. I want to use Codemirror.
I can add the html tag without a problem, but getting the cursor location inside of the appended tag is where I'm having trouble.
editor.replaceRange("<strong></strong>", editor.getCursor());

Add the following code to move cursor to center of tag. Also I updated your code, Please use the below link for accessing it
http://liveweave.com/LLq9GS
$(".bold").click(function() {
// For codemirror & center cursor
editor.replaceRange("<strong></strong>", editor.getCursor());
editor.focus();
var str="</strong>";
var mynum=str.length;
var start_cursor = editor.getCursor(); //I need to get the cursor position
console.log(start_cursor); //Cursor position
var cursorLine = start_cursor.line;
var cursorCh = start_cursor.ch;
//Code to move cursor back [x] amount of spaces. [x] is the data-val value.
editor.setCursor({line: cursorLine , ch : cursorCh -mynum });
