I have created a form which can be dynamically changed using the buttons included. These buttons allow for more input fields to be added/removed. The issue is that the input fields created are not posting any data/ Values in those fields not being added to the $POST array on the submit of the form.
The main functions below resposible for adding and removing rows is RemoveRows() and addRows()
What should happen is that on submit all values in the form should be "posted" then I can access all of those fields via $_POST["nameOfField"].
The way I have currently approached this is to create an input fields with the relevant id's and names then append that field to where the "hard coded" fields exists.
From my initial debugging none of the fields that have been added via javascript are in $Post which I have checked via var_dump($_REQUEST);
I have also seen that the nodes that are added are not elements of the form tag even though the nodes are added between the opening and closing tag. This can be seen in the doBeforeSubmit() Function where we can see all elements that are children of the and this never changes as rows are added/removed.

PHP:
<?php
var_dump($_REQUEST)

UPDATE:
The code has been changed to use a php array by adding square brackets into the name which produces the following html:
<input type="text" id="partNum0" class="form-control" name="partNum[]">
<input type="text" id="partNum1" name="partNum[]" class="form-control">
<input type="text" id="partNum2" name="partNum[]" class="form-control">
You just need to use the name property of the input and add [] at the end, as GrumpyCrouton said. PHP parse it as an array, and you can access it as:
$partNum = $_POST["partNum"];
FIXED: It turns out the above code did not have any issues with the logic or the way it should work, in the source code in visual studio the indentation of some of the Divs was off causing the browser to have issues in rendering the form correctly hence why the added boxes were not included in the form and their values not POSTED.
As a heads up to anyone with maybe a similar issue, it pays to have your code neat.

You can try in html with below button type as well.
<input type="reset" value="Reset">
If you want reset form from javascript then
document.getElementById("your-form-id").reset();
Change
1. <form class="form-inline">
2. refresh3.addEventListener("click", emptyInput);
to
1. <form class="form-inline" id="form">
2. document.getElementById("btnRefresh3").addEventListener("click", emptyInput);
3. function emptyInput() {
document.getElementById("form").reset();
}
I'm beginner in JS.
I have 2 functions. How to do :
if I click first button, make first function work, if I click second button, make second function work?
Apply pressed button value to function and then apply it to input field.
Example: when I type 'ABC' using Caesar Cipher , it would return 'NOP', when I type 'ABC' using my cipher (or any other), it would return 'BCD' (or any other value, it depends on which cipher is selected). Thanks everyone in advance

I whipped up a simplified example of contextually switching input handler functions for you, here ya go:
// use an object as a key-value store for your functions
var funcs = {
caesar: encryp1, // i dont know if i got these the right way around :D
mine: encryp2
}
// store which funciton is currently selected in a variable
var selected = "caesar"
// call this function just to show the default selected function
determineOutput()
// CAESAR
$("#caesarButton").click(function() {
console.log("caesar button clicked!")
// here assign which function to use
selected = "caesar"
determineOutput()
});
//MINE
$("#mineButton").click(function() {
console.log("mine button clicked!")
// here assign which function to use
selected = "mine"
determineOutput()
});
$('#field1').on('keyup keypress blur', function () {
// this function is alled every time one of the events
// listed happens on the #field1 element
determineOutput()
});
function determineOutput(){
var textvalue = $('#field1').val();
//use the function currently selected by addressing it with
// [] on the funcs object
var correctFunction = funcs[selected]
// then call the selected function with the input text
$('#field2').val(correctFunction(textvalue));
// show the user which cipher we're using
$("#currentCipher").html("current cipher:" + selected)
}
function encryp1(tekst) {
var result = "";
var str = tekst.toUpperCase();
for (var i=0; i<str.length ; i++) {
var ascii = str[i].charCodeAt();
if(ascii>=65 && ascii<=77) {
result+=String.fromCharCode(ascii+13);

I have a html form, where user need to enter the name and address of their office. The number of offices are dynamic.
I want to add an Add More button, so that users can enter the details of any number of offices.
My question is, how can I create an array of inputs where new elements can be added and removed using JavaScript. Currently, I'm doing it using js clone method, but I want an array, so that input data can easily be validated and stored to database using Laravel.
What I'm currently doing..
This is my HTML form where users have to enter the address of their clinic or office. I've taken a hidden input field and increasing the value of that field whenever a new clinic is added, so that I can use loop for storing data.
<div class="inputs">
<label><strong>Address</strong></label>
<input type="text" class="hidden" value="1" id="clinicCount" />
<div id="addresscontainer">
<div id="address">
<div class="row" style="margin-top:15px">
<div class="col-md-6">
<label><strong>Clinic 1</strong></label>
</div>
<div class="col-md-6">
<button id="deleteclinic" type="button" class="close deleteclinic"
onclick="removeClinic(this)">×</button>
</div>
</div>
<textarea name="address1" placeholder="Enter Clinic Address" class="form-control"></textarea>
<label class="text-muted" style="margin-top:10px">Coordinates (Click on map to get coordinates)</label>
<div class="row">
<div class="col-md-6">
<input class="form-control" id="latitude" type="text" name="latitude1" placeholder="Latitude" />
</div>
<div class="col-md-6">
<input class="form-control" id="longitude" type="text" name="longitude1" placeholder="Longitude" />
</div>
</div>
</div>
</div>
</div>
<div class="text-right">
<button class="btn btn-success" id="addclinic">Add More</button>
</div>
And my js code..
function numberClinic(){
//alert('test');
var i=0;
$('#addresscontainer > #address').each(function () {
i++;
$(this).find("strong").html("Clinic " + i);
$(this).find("textarea").attr('name','name'+i);
$(this).find("#latitude").attr('name','latitude'+i);
$(this).find("#longitude").attr('name','longitude'+i);
});
}
$("#addclinic").click(function(e){
e.preventDefault();
$("#addresscontainer").append($("#address").clone());
numberClinic();
$("#addresscontainer").find("div#address:last").find("input[name=latitude]").val('');
$("#addresscontainer").find("div#address:last").find("input[name=longitude]").val('');
$("#clinicCount").val(parseInt($("#clinicCount").val())+1);
});
function removeClinic(address){
if($("#clinicCount").val()>1){
$(address).parent('div').parent('div').parent('div').remove();
$("#clinicCount").val(parseInt($("#clinicCount").val())-1);
}
numberClinic();
}
This way, I think I can store the data to the database but can't validate the data. I'm using the laravel framework.
One way you could do this is by using the position of the input in the parent as the index in the array, then saving the value in the array every time each input is changed. Then you can just add and remove inputs.
Sample code:
var offices = document.getElementById('offices');
var output = document.getElementById('output');
var data = [];
var i = 0;
document.getElementById('add').addEventListener('click', function() {
var input = document.createElement('input');
input.setAttribute('type', 'text');
input.setAttribute('placeholder', 'Office');
var button = document.createElement('button');
var index = i++;
input.addEventListener('keyup', function() {
for (var i = 0; i < offices.children.length; i++) {
var child = offices.children[i];
if (child === input) {
break;
}
}
// i is now the index in the array
data[i] = input.value;
renderText();
});
offices.appendChild(input);
});
document.getElementById('remove').addEventListener('click', function() {
var children = offices.children;
if (children.length === data.length) {
data = data.splice(0, data.length - 1);
}
offices.removeChild(children[children.length - 1]);
renderText();
});
function renderText() {
output.innerHTML = data.join(', ');
}

I would like to know how can I create textboxes and insert data at page load.
What I'm trying to do is open an array string from a database, create the textboxes and populate the textboxes at page load.
I have an array string from an ms sql database that looks something like this
test,test;bla;bla2;test44;test55;test66
I separated each individual array with ; and I would like to create textboxes and insert the values into a textbox, one-by-one, so the end result would look like this:
I don't know how to do it using the code below.
Whatever I try I mess up the add/remove functions or I end up cloning all textboxes when the plus button is clicked.
THANKS

Here's what I changed to your code :
Changed the template which was a <script> to a <div>, and hid it by default using style="display: none;" :
<div id="template_add_form" type="text/template" style="display: none;">
Initialized array empty, so that we can put our own first line : formArray = [ ],
Created a function to add a string in the form :
var addToForm = function (stringValue) {
values = stringValue.split(";");
for (var i = 0; i < values.length; i+=3) {
var newLine = clone($template);
var fields = newLine.find('.form-control');
var toAdd = Math.min(values.length-i, 3);
for (var j = 0; j < toAdd; j++) {
fields[j].value = values[i+j];
}
formArray.push(newLine);
}
}
At the end, I added some example data, then pushed an empty line and updated the form :
addToForm("2;3;4;5;6;7");
formArray.push(clone($template));
updateForm();
EDIT : I also deleted the template div at the end so that it isn't taken into the form when you submit :
$('#template_add_form').remove();
To be able to do that, I cloned it entirely at start :
$template = $('<div>').addClass("entry input-group col-xs-9").append(clone($('#template_add_form'))),
I have several div tags with the class of opt that have an input and button element inside them. I am trying to create a function that will take the value from the input tag and when you click the button, the next input and button field will pop up and ask you to enter different information, while the previous input and button tags will hide itself. However, the function is not working here is the jsfiddle.
HTML
<div id="container">
<div class="opt active"> <input type="text" placeholder ="Enter Name"name="name"> <button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder ="Enter Age" name="age"> <button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder ="Enter Race" name="race"> <button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder ="Enter Sex" name="sex"> <button id="done">Done</button>
</div>
</div>
Javascript
function init(){
var opt = document.getElementsByClassName('opt');
var num = 0;
var prop = [];
var propVal = [];
for (var i = 0 ; i < opt.length; i++)
{
opt[i].querySelector('input').value = "";
}
opt[num].querySelector('button').onclick = function()
{
prop[num] = opt[num].querySelector('input').name;
propVal[num]= opt[num].querySelector('input').value;
opt[num].className = "opt";
opt[num+1].className ="opt active";
console.log(prop +" "+ propVal);
num++;
};//button function
}
init();
You need bind the click handlers in the loop as well. You also don't need to use parallel arrays to store the properties when you could use an object instead.
Make sure that there is a "next input" before trying to change the class of the next one.
var opt = document.getElementsByClassName('opt'),
num = 0, prop = {};
function nextInput() {
var input = opt[num].querySelector('input');
prop[input.name] = input.value;
console.log(prop);
opt[num].className = "opt";
if (num + 1 < opt.length) {
opt[num + 1].className = "opt active";
num++;
} else {
// submit?
}
}
for (var i = 0; i < opt.length; i++) {
opt[i].querySelector('input').value = "";
opt[i].querySelector('button').onclick = nextInput;
}
.opt { display: none }
.opt.active { display: block }
<div id="container">
<div class="opt active">
<input type="text" placeholder="Enter Name" name="name">
<button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder="Enter Age" name="age">
<button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder="Enter Race" name="race">
<button>OK</button>
</div>
<div class="opt">
<input type="text" placeholder="Enter Sex" name="sex">
<button id="done">Done</button>
</div>
