Trying to add new form fields for additional data and getting weird return

I have a jquery script that is supposed to create new table and input fields with a _1 for the new data field. The code does add the table and the fields however the input fields have this when doing a view source of the code.
I am not sure why I am getting [object Object]1 for the form fields.
Also if I add an additional table the other fields get this.
visitor_first_name_NaN where this should be 2 or 3
I am sure I am missing something just not sure what. If anyone has an idea or a fix it would be great.
<script type='text/javascript'>//<![CDATA[

jQuery("##visitorRegFrm").validate({
errorElement : "div",

how to serialize a form under specific conditions

Taka a look at this fiddle here this is a form where a business user enters the offered services.I sent the data with ajax and by serializing the form.
Click edit and add(plus sign) a service...in the example an input is added where it's name attribute value is of this **form= form[5]...**contrast with this with the form of the name attribute value in the other inputs...only the newly added services have the name attribute like this and the reason for that is to serialize only these...and not the others already present in the DOM/stored in the DB.
And now my problem:
Imagine that the user goes to edit the already registered services(or that he goes to edit them and add a new one)...at this case the already registered services wont'be serialized cause of the form the name attribute value has...(and the reason for this is explained above).
What can I do in this case?Sometimes I must serialize only part of a form and sometimes whole of the form.If all the inputs have name attribute value of form[1....] then along with the newly added input...already registered services will be serialized again.
Thanks for listening.
Code follows(you can see it in the fiddle too)
$('.editservices').click(function() {
//console.log(('.wrapper_servp').length);
originals_ser_input_lgth = $('.services').length;
var originals = [];

I have an Idea for you. What you can do is when you show the currently existed value in you html instead of giving name attribute just give data-name attribute. I.e
Change this
<input class="services text" data-service="21" size="40" value="hair" type="text" name="service0" readonly="">
To This
<input class="services text" data-service="21" size="40" value="hair" type="text" data-value="hair" data-name="service0" readonly="">
Now when user update this values you can bind an event in jQuery like below.
$(document).ready(function(){
$(".services input").on("change paste keyup", function() {
if($(this).val() === $(this).attr("data-value"))
{
$(this).removeAttr("name");
}else{
$(this).attr("name",$(this).attr("data-name"));
}
});
});
By this way you can give name attribute to only those elements whose values are changed. Now each time you can serialize the whole form and it will only get the value of changed elements.
Don't forget to give unique class to already existed elements so you can bind on change event. Hope its clear to you.

I want to remove an array item when generated check box checked

I made a todolist which is taking value from input and add an item from array so when the given value shown in page i want to remove an item form array whn checkbox checked.
Html part :
<input type="text" id="field" placeholder="Type name" />
<button type="submit" onclick="insertitem()">Submit</button>
<p id="para"></p>
javascript part:
var list = [];
var input;
function insertitem() {
input = document.getElementById('field').value;
list.push(input);
DisplayItem(list);
document.getElementById('field').value='';
}
function DisplayItem(data) {
var contain = document.getElementById('para');
contain.innerHTML='';
for ( var i in data) {
contain.innerHTML +="<div><input id='box' onClick='remove()' type='checkbox' /><label>" + data[i] + "</label></div>";
}
}
function remove() {
var check = document.getElementById('box').value;
for ( var i in list) {
if (list[i]!= check) {
}
}
}

Try this with pure javascript :
Array.splice and Array.indexof()
Add with checkbox inside the label tag.
And click event change with remove(this).Then easly find the label
text and match with list array.
contain.innerHTML +="<div><label><input id='box' onClick='remove(this)' type='checkbox' />" + data[i] +
"</label></div>";
}
var list = [];
var input;
function insertitem() {
input = document.getElementById('field').value;
list.push(input);
DisplayItem(list);
document.getElementById('field').value='';
}
function DisplayItem(data) {
var contain = document.getElementById('para');
contain.innerHTML='';
for ( var i in data) {
contain.innerHTML +="<div><label><input id='box' onClick='remove(this)' type='checkbox' />" + data[i] +
"</label></div>";
}
}
function remove(that) {
var check = that.parentElement.textContent;
//that.remove() if you need remove clicked box
for ( var i in list) {
if (list[i] == check) {
list.splice(list.indexOf(check),1);
}
}
console.log(list)
}
<input type="text" id="field" placeholder="Type name" />
<button type="submit" onclick="insertitem()">Submit</button>
<p id="para"></p>

var list = [];
var input;
function insertitem() {
input = document.getElementById('field').value;
list.push(input);
DisplayItem(list);
document.getElementById('field').value='';
}
function DisplayItem(data) {
var contain = document.getElementById('para');
contain.innerHTML='';
for ( var i in data) {
contain.innerHTML +="<div id='remove" + i + "'><label for='box" + i + "'><input id='box" + i + "' onClick='remove(" + i + ")' type='checkbox' />" + data[i] + "</label></div>";
}
}
function remove(targetId) {
var check = document.getElementById('box' + targetId).checked;
if(check){
console.log('Remove box' + targetId);
document.getElementById('remove' + targetId).innerHTML='';
}
}
<input type="text" id="field" placeholder="Type name" />
<button type="submit" onclick="insertitem()">Submit</button>
<p id="para"></p>
I just modified your JavaScript to pass an ID with a number to set each label apart from each other..

Jquery custom filters in HTML

Filters must fulfill,comatibile with:
Take limits to attention in add, remove and change. If limit is equal to instance of length in HTML document filter must be disabled
Basic filters are users, title when filters is only one this two option must be not disabled rest must be disabled when event is add, remove or change
Any ideas how I could do that? I try various method but result always are the same , filters is not compatibile.
If you want some more information how it should work just say.
I see it like this when add,remove and change:
if(users.length >= limit){
//set all option in select where filter is user to disabled = true
}
if(title.length >= limit){
//set all option in select where filter is title to disabled = true
}
if(filters.length > 1){
//options in select set to disable=false
}
if(filters.length < 1){
//options in select set to disable=true and title, users set to false
}

How to get the values of all textfields in add/remove textfields and form JSON

I'm using a plugin to duplicate textfields on add and remove buttons. Now, after getting the fields added and removed, I want to form JSON out of all the textfields and POST it on submit.
Below is the code -
$(function () {
var scntDiv = $('#p_scents');
var i = $('#p_scents p').size() + 1;
$('#addScnt').live('click', function () {
$('<p><label for="p_scnts"><input type="text" id="p_scnt_' + i + '" size="20" name="p_scnt_' + i + '" value="" placeholder="Input Value" /></label> Remove</p>').appendTo(scntDiv);
i++;
return false;
});
$('#remScnt').live('click', function () {
if (i > 2) {
$(this).parents('p').remove();
i--;
}
return false;
});
});
JSFiddle can be referred to.
I want to get the values of all textfields and form JSON.

Iterate through the input fields, grab their values, and push them through JSON.stringify to create your desired JSON.
function serializeAndPost() {
var values = [];
$( '#p_scents input[id^=p_scnt_]' ).each( function ( index, element ) {
values.push( element.value );
} );
var json = JSON.stringify( { "welcomesList": values } );
// Do your POSTing here
}
Updated fiddle:
https://jsfiddle.net/tZPg4/11019/

I don't know if this is the best solution as I am building a string rather than an JSON object but here is my solution:
HTML
<input type="button" id="btnSubmit" value="Submit"></input>
JS:
$(function () {
var scntDiv = $('#p_scents');
var i = $('#p_scents p').size() + 1;
$('#addScnt').live('click', function () {
$('<p><label for="p_scnts"><input type="text" id="p_scnt_' + i + '" size="20" name="p_scnt_' + i + '" value="" placeholder="Input Value" /></label> Remove</p>').appendTo(scntDiv);
i++;
return false;
});
$('#remScnt').live('click', function () {
if (i > 2) {
$(this).parents('p').remove();
i--;
}
return false;
});
$('#btnSubmit').click(function(e) {
e.preventDefault();
var str = [];
$.each($('input[type=text]'), function(i, val) {
var el = $(this);
str.push('"' + el.attr("id") + '":"' + el.val() +'"');
});
var json_string = "{" + str + "}";
});
});
