JavaScript remove element from multiple select boxes - javascript

I have a form where I have a select box and a drop down menu with two buttons and a text field. Enter an item into the text field and it gets added to BOTH the select box above AND the drop down menu. I can figure out how to remove the selected item from the select box but how do I ALSO remove it from the drop down menu??
Working JS FIDDLE EXAMPLE
NOTE: On the actual form these will be on different tabs so you won't be able to see them at the same time, the list just needs to populate from one area to the other.
CSS
#sbox {
overflow: hidden;
width: 200px;
}
HTML
<select id="sbox" name="selectbox" size="5"></select>
<BR>
<button type="button" class="btn btn-default" onclick="DeleteProbs();">Delete Selected Problem</button>
</td>
</tr>
<tr>
<td colspan="2" valign="top"><p>To add a problem to the list, type it in the New Problem text field and then click "Add to List". To remove a problem, click it in the list, then click, "Delete Selected Problem"<P>
<strong>New Problem</strong><P>
<input type="text" id="ProbAreaFrom">
<P>
<button type="button" class="btn btn-default" id="ProbListBtn" onclick="ListProbs();">Add to List</button>
</p>
Problem being detailed:<BR>
<select name="select" id="dbox">
</select>
JAVASCRIPT
function ListProbs() {
var x = document.getElementById("sbox");
var txt1 = document.getElementById("ProbAreaFrom").value;
var option = document.createElement("option");
option.text = txt1
x.add(option);
ListProbs2();
}
function ListProbs2() {
var y = document.getElementById("dbox");
var txt1 = document.getElementById("ProbAreaFrom").value;
var option = document.createElement("option");
option.text = txt1
y.add(option);
ProbAreaFrom.value="";
}
function DeleteProbs() {
var x = document.getElementById("sbox");
for (var i = 0; i < x.options.length; i++) {
if (x.options[i].selected) {
x.options[i].remove();
}
}
}

function DeleteProbs() {
var x = document.getElementById("sbox");
var y = document.getElementById("dbox");
var val;
for (var i = 0; i < x.options.length; i++) {
if (x.options[i].selected) {
val = x.options[i].value;
x.options[i].remove();
}
}
for (var i = 0; i < y.options.length; i++) {
if (y.options[i].value == val) {
y.options[i].remove();
}
}
}

working fiddle. Added a button to remove selected item from select element. The function's name is
DeleteProbs2

What im trying to do is within cel 5 (delete entry) is to add a delete button to each row that is entered into the table that will remove that row but don't know how to go about this. Ideally would like to do this without the use of JQuery if possible, since i've not touched upon it as of yet.
You can use the rowIndex property to delete the row.
function addRow() {
// get input values
var name = document.getElementById('name').value;
var currentAge = document.getElementById('currentAge').value;
var Birthday = document.getElementById('Birthday').value;
var carType = document.getElementById('carType').value;
var table = document.getElementsByTagName('table')[0];
const index = table.rows.length;
var newRow = table.insertRow(index);
newRow.setAttribute('data-index', index);
var cel1 = newRow.insertCell(0);
var cel2 = newRow.insertCell(1);
var cel3 = newRow.insertCell(2);
var cel4 = newRow.insertCell(3);
var cel5 = newRow.insertCell(4);
cel1.textContent = name;
cel2.textContent = currentAge;
cel3.textContent = Birthday;
cel4.textContent = carType;
cel5.innerHTML = '<button onclick="removeRow(this)" type="button" class="delete-button">Delete</button>';
}
function myFunction() {
var x = document.getElementById("table").rows.length;
document.getElementById("demo").innerHTML = "Found " + x + "tr elements in the table.";
}
function removeRow(evt) {
const deleteIndex = evt.parentElement.parentElement.rowIndex;
document.getElementById("table").deleteRow(deleteIndex);
}

What you should be doing is that you set the innerHTML of cel5 to a button, e.g.:
cel5.innerHTML = '<button type="button" class="delete-button">Delete</button>';
Then, you can simply add a click event listener on the table, and check if a click event has emitted from the button element. If it matches, you then delete the closest <tr> element:
document.getElementById('table').addEventListener('click', function(e) {
// Check if click event came from delete button
if (!e.target.classList.contains('delete-button'))
return;
e.target.closest('tr').remove();
});
See proof-of-concept example below:
function addRow() {
// get input values
var name = document.getElementById('name').value;
var currentAge = document.getElementById('currentAge').value;
var Birthday = document.getElementById('Birthday').value;
var carType = document.getElementById('carType').value;
var table = document.getElementsByTagName('table')[0];
var newRow = table.insertRow(table.rows.length / 2 + 1);
var cel1 = newRow.insertCell(0);
var cel2 = newRow.insertCell(1);
var cel3 = newRow.insertCell(2);
var cel4 = newRow.insertCell(3);
var cel5 = newRow.insertCell(4);
cel1.innerHTML = name;
cel2.innerHTML = currentAge;
cel3.innerHTML = Birthday;
cel4.innerHTML = carType;
cel5.innerHTML = '<button type="button" class="delete-button">Delete</button>';
}
function myFunction() {
var x = document.getElementById("table").rows.length;
document.getElementById("demo").innerHTML = "Found " + x + "tr elements in the table.";
}
document.getElementById('table').addEventListener('click', function(e) {
// Check if click event came from delete button
if (!e.target.classList.contains('delete-button'))
return;
e.target.closest('tr').remove();
});
<h2>Basic HTML table</h2> <button onclick="myFunction()">Press me for

In the head, add a function that understands rows and cells. Call some delete on a parent of a cell (Delete the <tr> in which the <td> is located at). then on the body add to each dynamic button an onClick event and set that function you created earlier ON.
You can use a script like this:
function deleteRow() {
var tableData = event.target.parentNode;
var tableRow = tableData.parentNode;
tableRow.parentNode.removeChild(tableRow);
}
In the button you create (dynamically or fixedly) you should add an onClick event. For example:
<tr>
<td>John Doe</td>
<td>$10,000</td>
<td><input type="submit" value="Delete" id="Delete" onclick="deleteRow()"></td>
</tr>

Loop through dynamically generated HTML elements with the same Class and build objects with their data

I am trying to collect data from a table that is dynamically generated on a button click. As you will see below, the button creates a new text box and a multiselect drop down. Currently, my code will only grab the first value from both the textbox and the dropdown.
My end goal is to create an object of key/values that will look like this:
{"group 1":[multiselect value, multiselect value], "group 2": [multiselect value, multiselect value, multiselect value], "group 3": [multiselect value, multiselect value]}
Below is my current code. Any guidance is appreciated!

How to select an option text matching those of an array value

I have an array with three elements, Im looping through that array to see the length of it so that it triggers a button click three times to dynamic add input select box. Each array value will go on each added select box and find if it match any option text if it does it have to select it. Below is my code not sure where I'm going wrong
var myArryValues = [
"Hello World",
"Javascript",
"Jquery"
]
for (var i = 0; i < myArryValues.length; i++) {
var bookIndex = 0;
$('#bookForm').on('click', '.mynewButton', function() {
$('.myDropdown').each(function(index) {
console.log("operatorString", operatorString);
var operatorCounter = 0;
var optionCounter = 0;
$(this).find('option').filter(function() {
if ($(this)[optionCounter] == myArryValues[operatorCounter]) {
$(this)[optionCounter].attr('selected', "selected");
operatorCounter++;
} else {
optionCounter++;
}
});
});
console.log("mynewButton");
bookIndex++;
var bookForm = $('#bookForm');
var $template = $('#bookTemplate'),
$clone = $template
.clone()
.addClass('myDropdown-row')
.removeClass('hide')
.attr('data-book-index', bookIndex)
.attr('id', '');
bookForm.append($clone);
// Update the name attributes
$clone
.find('[name="myDropdown"]').attr('name', 'myDropdown[' + bookIndex + '].myDropdown').end()
})
// Remove button click handler
.on('click', '.removeButton', function() {
$(this).parents('.form-group').remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<div class="row" id="bookForm" class="form-horizontal">
<div class="form-group">
<div class="col-md-2 button-div">

Try This on your click function
var data = ['bar','baz'];
for (var i = 0; i < data.length; i++) {
var s = $('<select id="'+i+'"/>');
for (var j = 0; j < data.length; j++) {
if (i==j) {
$('<option />', {value: data[j], text: data[j],selected:'selected'}).appendTo(s);
}else{
$('<option />', {value: data[j], text: data[j]}).appendTo(s);
}
}
s.appendTo('body');

Enter the values in the input fields and click " Add" button , The entered values gets added to the new row .
And When i click delete button, all the rows are getting deleted .
What I need to implement :
Checkbox should get added to every row .
If i select the checkbox and click "delete" button, only that particular row should get deleted and it should work if i select multiple check boxes as well.
3.Clear the Input fields after i click add button .
Can anyone check this out and tell me how to do that .

php codeigniter - managing values in multi select box

I am working on a multibox as a part of my codeigniter based project, here I am trying to move the values across the boxes using custom js code shared below
The values shown in first box are fetched from db when page loads and used to move the required values to second box using javascript. My goal it that the values already moved to second box should not be visible in the first box after saving the data and at the same time source data for the first box should not be altered.
Right now I am able to select the values to second box and save successfully but when I load the page again after saving I am seeing the moved values in the fist box and this is visually creating duplication of values and would confuse the user. On the other hand if I try to move back the values to the first box which is creating a conflict while saving the data.
Is there any way I could change my code so that moved values will not be available in the first box again
