Dynamic add/delete input rows javascript,jquery

The dynamic add/delete input rows is not working properly. The rows are created using add function, but it is not deleted properly. Basically the delete function call is not working.
$(document).ready(function(){
var counter = 1; //initlal text box count
$("#addButton").click(function () {
if(counter > 3){
alert("Only 3 textboxes allowed");
return false;
}
var selectfield = $('#selectcolumnlist option:selected').val();
var newTextBoxDiv = $(document.createElement('div')).attr("id", 'TextBoxDiv');
newTextBoxDiv.after().html('<label>'+ selectfield + ' : </label>' + '<input type="text" name="textbox_' + selectfield + '" id="textbox_'+selectfield+'" placeholder="' + selectfield + '" value="" /><input type="button" value="Remove Button" class="remove_this" id="removeid" />');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
alert(counter);
});
$("#removeid").click(function() {
alert("i'm in");
});
}

Assuming you're creating elements in a correct way, I mean, using unique ids, you should use event-delegation:
// This example selects the element with the class
// .removeid (here you need to set a specific class) or set something unique
// per new dynamically created element.
$("#TextBoxesGroup").on('click', '.remove_this', (function() {
alert("i'm in");
}));

How to add a function to an appended element

I have an input-text. If you type something, the text appears below (see code snippet).
Now, I need to do the same with a previous step: clicking a button (preferably a checkbox) to append/remove all. Here is my failed idea: DEMO (it appends the input text, but when you type, text won't apear below like it does on my code snippet).
I feel like the function to add text below does not work because there is a problem with selecting the appended element. How do I do this?
Any more simple idea to do this would be great
var name1 = document.getElementById('name');
name1.addEventListener('input', function() {
var result = document.querySelector('.X');
console.log(this.value );
result.innerHTML = this.value;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>What is your name? </label><input type="text" id="name">
<p>Your name is: <span class="X"></span></p>

Put your first part of the snippet into appending logic while clicking the add button. As in your codes, the input box is appended to the document after its listener being attached.
if (!added) {
$content = $(NewContent).appendTo('.firstappend');
// attach listener after input box actually exists!
var name1 = document.getElementById('A');
name1.addEventListener('input', function() {
var result = document.querySelector('span.Y');
console.log(this.value );
result.innerHTML = this.value;
});
}

$(function() {
let NewContent = '<div class="added">' +
'<p>' +
'<label>What is your name? </label>' +
'<input type="text" id="A">' +
'</p>' +
'<p>Your name is: <span class="Y"></span></p>' +
'</div>';
$(".addremove").on('click', function() {
if ($(".added").length) {
$(".added").remove();
} else {
$(".firstappend").append(NewContent);
}
});
$(document).on('change keyup', '#A', function(event) {
$("span.Y").html($(event.currentTarget).val());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="toadd">
<button type="button" class="addremove">Do you have a name?</button>
</div>
<div class="firstappend"></div>
as from the DEMO you included,
appended elements to document cannot be invoked explicitly, since you're using jQuery, you can do this
$(document).on('change keyup', '#A', function(event) {
$("span.Y").html($(event.currentTarget).val());
});

How to get the value from dynamically created checkbox using Jquery with class

I am trying to get the value from checkbox when checked which is created dynamically with jquery associated with html table am using class to get the value but am unable to get it
My code is like this
Input created with Jquery
"<td><div class=" + "checkbox checkbox-primary" + "><input type=" + "checkbox" + " class=" + "cbCheck" + " value=" + "" + data.d[i].Rowname + "" + "" + data.d[i].one + "" + "></div></td>"
Jquery to get the value
$("#table").on(":checked", ".cbCheck", function () {
var id = $(this).attr("value");
alert(id);
});
Please help me how to fix this.
Thanks in advance

Working Fiddle
Try:
$('table tr td').on('click','.cbCheck',function() {
if ($(this).is(':checked')) {
alert($(this).attr('id'))
}
else
alert('unchecked');
});

Use 'change' event:
$("#table").on("change", ".cbCheck", function () {
var id = $(this).attr("value");
alert(id);
});

Instead of creating it like that
use Create element and add id dynamically then use your function I guess it will work, actually worked in my case
var newCheckBox = document.createElement('input');
newCheckBox.type = 'checkbox';
newCheckBox.id = 'ptworkinfo';

You can do using following for dynamically created elements:
$(document).on("click", ".cbCheck", function () {
var value=$(this).attr("value");
alert(value);
});

Renaming form fields added or deleted dynamically

I'm looking for help to rename the name attributes of some fields created dynamically.
Now, my code assigns new values to the added fields (it increments according to the length of the div) but the problem appears when I delete a field, I don't know how to rename the remaining according to the number of fields deleted.
jQuery:
$(document).ready(function () {
$("#add").click(function () {
var intId = $("#reglas div").length;
var fieldWrapper = $('<div></div>', {
class: 'fieldwrapper',
id: 'field' + intId
});
var fPath = $('<input align="left" type="text" placeholder="Path" class="reglas_wrapper" id="path" name="field1_' + intId + '" required /> ');
var fTTL = $('<input type="text" class="reglas_wrapper" placeholder="TTL" id="ttl" name="field2_' + intId + '" required />');
var removeButton = $('<input align="right" type="button" id="del" class="remove" value="-" /> <br><br>');
removeButton.click(function () {
$(this).parent().remove();
});
fieldWrapper.append(fPath);
fieldWrapper.append(fTTL);
fieldWrapper.append(removeButton);
$("#reglas").append(fieldWrapper);
});
$("#cache").each(function () {
$(this).qtip({
content: {
text: $(this).next('.tooltiptext')
}
});
});
});
$('#formsite').on('submit', function (e) {
//prevent the default submithandling
e.preventDefault();
//send the data of 'this' (the matched form) to yourURL
$.post('siteform.php', $(this).serialize());
});
HERE'S MY FULL CODE: http://jsfiddle.net/34rYv/131/

You will want an incrementor. Check out this updated fiddle.
Here is the beginning of the code:
$(document).ready(function() {
var myIncr = 0;
$("#add").click(function() {
myIncr++;
var intId = myIncr;

You can add a class or id to each input field, and then depending on that class or id add the name as
<input type="text" class="something" />
Use this jQuery:
var classval = $('input[type=text]').attr('class'); // get class..
// now add the name as
$(this).attr('name', classval);
You can have as many inputs, they will be added the name depending on their class or id!
So even if the input fields are deleted, you will still have the class attributes in the control!

jQuery text to input?

I have a simple layout with a textblock and one <a>, like:
text1 edit
When I click on the <a>, I want this textblock to become text input. How is that possible with jQuery?

Use jQuery replaceWith():
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
$(this).parent().replaceWith("<input />");
});
});
http://jsfiddle.net/Dqkyg/1/
Furthermore, you can fill the textbox with the text outside the link like so:
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
var txt = $(".text").html();
$(".text").replaceWith("<input value='" + txt + "' />");
});
});
http://jsfiddle.net/Dqkyg/5/
The following will replace the edit with Save & Cancel options:
<div>
<span class="text">testing</span> <a href='#'>test</a>
</div>
$(document).ready(function(){
$("a").click(function(e){
e.preventDefault();
var txt = $(".text").html();
$(".text").replaceWith("<input value='" + txt + "' />");
$(this).replaceWith("<a href='#'>Save</a> | <a href='#'>Cancel</a>");
});
});
http://jsfiddle.net/Dqkyg/6/

There are plenty of plugins that you can use... No need to reinvent the wheel

Hmm ... ur a bit unclear... but
http://jsfiddle.net/mMYrf/4/
<div class="dataGrid">
<span>test</span>
edit
</div>
And
$('.dataGrid a').click( function(e) {
e.preventDefault();
var EditGrid = $(this).parent().children('span');
var DataTxt = EditGrid.text();
var InputHtml = '<input type=text" value="'+DataTxt +'" />';
$(this).text('Save?');
EditGrid.html(InputHtml);
});

<div class="editable">This is the content.</div>
<script type="text/javascript">
$(function() {
$('.editable').each(function() {
var a = $('edit');
(function(link, parent) {
link.click(function() {
link.remove();
var textField = $('<textarea/>').val(parent.html());
parent.replaceWith(textField);
delete parent, link;
});
})(a, $(this));
$(this).append(" ").append(a);
});
});
</script>
