create a "remove fields" button after new fields are dynamically added?

create a "remove fields" button after new fields are dynamically added? - javascript

I have a simple form that adds an extra row of fields on the click of
a green button.
I would like a 2nd red button to appear to the right of the green button
after the the green button is clicked for the 1st time.
I would like this red button to remove the most recent row of fields
added every time it is clicked
i would like for the red button to disappear when all added rows
have been removed.
Can anyone help me with this? I'm not very experienced with javascript or jquery obviously.
The code is as follows:
test.php
<form role="form">
<h3>
Band Details
<small>Enter each band name and primary contact information...</small>
</h3>
<div class="well" id="newBandRows">
<div class="row">
<div class="col-md-3">

At a high level, here are the steps you will need to implement:
Generate the HTML for the new red button.
This new red button will be hidden and unhidden based on a condition.
Example:
if (condition) {
$('#secondRedButton').hide();
} else {
$('#secondRedButton').show();
}
http://api.jquery.com/hide/
Bind an event handler to the "click" JavaScript event
Example:
$('#secondRedButton').click(function() {
// do something
});
https://api.jquery.com/click/
Please let me know if this helps.

You might as well use simple hiding statements as this:
var band_i = 0;
function addNewBandRow(con){
var e = con.getAttribute('name');
var c = document.getElementById('delBtn');
if(e == 'addRowBtn'){
band_i++;
var bandDiv = document.createElement('div');
bandDiv.innerHTML = '<div class="row" id="' + band_i + '"><div class = "col-md-3"><input type="text" class="form-control" id="newBandName' + band_i + '" name="newBandName' + band_i + '" placeholder="Enter Band Name"/></div><div class="col-md-3"><input type="text" class="form-control" id="primaryContact' + band_i + '" name="primaryContact' + band_i + '" placeholder="Enter Name"/></div> <div class="col-md-3"><input type="email" class="form-control" id="primaryEmail' + band_i + '" name="primaryEmail' + band_i + '" placeholder="Enter Email"/></div><div class="col-md-3"><input type="text" class="form-control" id="primaryPhone' + band_i + '" name="primaryPhone' + band_i + '" placeholder="Enter Phone #"/></div></div><br>';
document.getElementById('newBandRows').appendChild(bandDiv);
if(band_i != 0){
c.style.display = 'block';
}
}
}
function removeBandRow(con){
var e = con.getAttribute('name');
var c = document.getElementById('delBtn');
if(e == 'delRowBtn'){
var container = document.getElementById("newBandRows")
var nodes = container.childNodes;
container.removeChild(nodes[nodes.length - 1]);
band_i--;
if(band_i == 0)
c.style.display = 'none';
}
}
And modify buttons using this attributes.
<div class="col-md-1">
<button type="button" name="addRowBtn" class="btn btn-success pull-left" onClick="addNewBandRow(this);">+</button>
<button type="button" name="delRowBtn" id="delBtn" class="btn btn-danger pull-left" onClick="removeBandRow(this);" style='display:none' >-</button>
</div>

This should work for removing last child.
function removeBandRow(){
var container = document.getElementById("newBandRows")
var children = container.childNodes;
container.removeChild(children[children.length - 1]);
}

proplem in jquery when creating inputs cannot create a limit for the created elements

I am trying to create inputs with jquery when user click on specific button as i create the inputs i want them to stop creating if the number of inputs exceeds 10
and here is the code
<script>
$(document).ready(function(){
var inputs = $('.product-options').length;
var max_inputs = 15;
var i=inputs;
var number = inputs;
if(inputs < 2){
$('.add_field_button').click(function(e){
e.preventDefault();
number++
i++;
$('.form-product').append('<span id="row'+i+'" class="myinput" style="transition:1s ease;"><div class="form-group"> <div class="col-sm-7"> <input type="text" class="form-control product-options" name="childen'+number+'"'+'value="" placeholder="the option"></div><div class="col-sm-3"> <input type="text" class="form-control product-options" name="childprice'+number+'"'+ 'value="" placeholder="option price"></div> </div> <div class="form-group"> <div class="col-sm-7"> <input type="text" class="form-control product-options" name="childsrb'+number+'"'+'value="" placeholder="the option in serbian"></div><button type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove"><i class="fas fa-times"></i></button></div></span>');
});
}
$(document).on('click', '.btn_remove', function(){
var button_id = $(this).attr("id");
$('#row'+button_id+'').remove();
number--
i--;
});
});
</script>
html code
<div class="form-group product-option">
<label class="col-sm-2 control-label"></label>
<div class="col-sm-10 product-option">
<button type="button" class="add_field_button on-hover" style="background: none; border:none;">

<label for="option">Product options</label><br>
<div class="form-group product-option form-product">
</div>
</div>
</div>

You can use an if statement to check whether i is smaller than 11:
$(document).ready(function() {
var inputs = $('.product-options').length;
var max_inputs = 15;
var i = inputs;
var number = inputs;
if (inputs < 2) {
$('.add_field_button').click(function(e) {
e.preventDefault();
number++
i++;
if (i < 11) {
$('.form-product').append('<span id="row' + i + '" class="myinput" style="transition:1s ease;"><div class="form-group"> <div class="col-sm-7"> <input type="text" class="form-control product-options" name="childen' + number + '"' + 'value="" placeholder="the option"></div><div class="col-sm-3"> <input type="text" class="form-control product-options" name="childprice' + number + '"' + 'value="" placeholder="option price"></div> </div> <div class="form-group"> <div class="col-sm-7"> <input type="text" class="form-control product-options" name="childsrb' + number + '"' + 'value="" placeholder="the option in serbian"></div><button type="button" name="remove" id="' + i + '" class="btn btn-danger btn_remove"><i class="fas fa-times"></i></button></div></span>');
}
});
}
$(document).on('click', '.btn_remove', function() {
var button_id = $(this).attr("id");
$('#row' + button_id + '').remove();
number--
i--;
});
});

Add new row (html form) after click 'Add row' button

Hi , I would to ask how to add new row after we click on the 'Add row' button. I found some Javascript code and try to edit it but it doesn't work. Thank you in advance :) Here is the code that I have been using. Would you guys tell what to do or share with me any sources regarding this matter since I haven't found one. There are some similar questions in Stackoverflow but there's no answers there.
The html code :
<h1 class="h3 mb-4 text-gray-800">Requirement Validation Principles</h1>
<div class="jumbotron jumbotron-fluid">
<div class="container">
<form>
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName1"></label>
<input type="Name" class="form-control" id="inputName1" placeholder="Name">
</div>
<div class="form-group col">
<label for="inputPassword1"></label>
<input type="name" class="form-control" id="inputPassword1" placeholder="Position">
</div>
</div>
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName2"></label>
<input type="Name" class="form-control" id="inputName2" placeholder="Name">
</div>
<div class="form-group col">
<label for="inputPassword2"></label>
<input type="name" class="form-control" id="inputPassword2" placeholder="Position">
</div>
</div>
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName3"></label>
<input type="Name" class="form-control" id="inputName3" placeholder="Name">
</div>
<div class="form-group col">
<label for="inputPassword3"></label>
<input type="name" class="form-control" id="inputPassword3" placeholder="Position">
</div>
</div>
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName4"></label>
<input type="Name" class="form-control" id="inputName4" placeholder="Name">
</div>
<div class="form-group col">
<label for="inputPassword4"></label>
<input type="name" class="form-control" id="inputPassword4" placeholder="Position">
</div>
</div>
</div>
<button id="btn">Add row</button>
The javascript code :
var count=1;
$("#btn").click(function(){
$("#container").append(addNewRow(count));
count++;
});
function addNewRow(count){
var newrow='<div class="row">'+
'<div class="col-md-4">'+
'<div class="form-group label-floating">'+
'<label class="control-label">Name '+count+'</label>'+
'<input type="text" class="form-control" v-model="act" >'+
'</div>'+
'</div>'+
'<div class="col-md-4">'+
'<div class="form-group label-floating">'+
'<label class="control-label">Position '+count+'</label>'+
'<input type="text" class="form-control" v-model="section">'+
'</div>'+
'</div>'+
'</div>';
return newrow;
}

Here is the code that perfectly working.
<div class="jumbotron jumbotron-fluid" id="dataAdd">
<div class="container">
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName1"></label>
<input type="Name" class="form-control" id="inputName1" placeholder="Name" v-model="name">
</div>
<div class="form-group col">
<label for="inputPassword4"></label>
<input type="name" class="form-control" id="inputPassword1" placeholder="Position" v-model="position">
</div>
</div>
</div>
<button id="btn">Add row</button>
HTML Code input start with one.
$("#btn").click(function(){
var len=$('#dataAdd .container .form-row').length+1;
//if(len>1)
$("#dataAdd .container:last").append(' <div class="form-row">'+
'<div class="form-group col-md-7">'+
' <label for="inputName'+len+'"></label>'+
' <input type="Name" class="form-control" id="inputName'+len+'" placeholder="Name" v-model="name">'+
' </div>'+
' <div class="form-group col">'+
' <label for="inputPassword4"></label>'+
' <input type="name" class="form-control" id="inputPassword'+len+'" placeholder="Position" v-model="position">'+
' </div>'+
'</div>');
});
});
JavaScript Code added HTML in last form-control.
I have Created a working Example you can check here

Turns out there's a Javascript method called insertRow().
You'd just need to get a handle on your form by giving it and ID and then accessing that in Javascript:
var table = document.getElementById("[the ID I gave my form");
after that, use the insertRow() method on that table variable and give it a position. Then add cells to the row you just created using insertCell():
var row = table.insertRow(0);
var cell1 = row.insertCell(0);

Instead of using InsertRow() you can alternatively put the button outside your container (the div containing the "container" class) and then use javascript to create your elements.
After all elements are created, you can simply append them to follow your desired structure.
const button = document.getElementById(#btn);
button.addEventListener('click', addRow);
function addRow(event) {
const container = document.querySelector('.container');
const row = document.createElement('div');
row.classList.add('form-row');
const group = document.createElement('div');
group.classList.add('form-group');
group.classList.add('col-md-7'); // Adjust after need.
const label = document.createElement('label');
label.setAttribute('for', 'myNewInputName');
const input = document.createElement('input');
input.setAttribute('type', 'text');
input.classList.add('form-control');
input.setAttribute('placeholder', 'My new placeholder');
// Assemble our structure.
group.appendChild(label);
group.appendChild(input);
row.appendChild(group);
container.appendChild(row);
}

the more simple is to use a DOMParser
const DomParser = new DOMParser()
, myForm = document.getElementById('my-form')
, bt_Add = document.getElementById('btn-add')
;
function newRow(numRow)
{
let row_N = `
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputName${numRow}"></label>
<input type="Name" class="form-control" id="inputName${numRow}" placeholder="Name ${numRow}">
</div>
<div class="form-group col">
<label for="inputPassword${numRow}"></label>
<input type="name" class="form-control" id="inputPassword${numRow}" placeholder="Position ${numRow}">
</div>
</div>`
return (DomParser.parseFromString(row_N, 'text/html')).body.firstChild
}
bt_Add.onclick =()=>
{
let rowCount = myForm.querySelectorAll('div.form-row').length
myForm.appendChild(newRow(++rowCount))
}

Do not use same id for multiple elements, user class instead of id. See below code to get amount
$(function(){
$(document).on("blur", "div.row .col-md-3 input[name='estamount[]']", function(){
var $row = $(this).closest('.row'); // get parent row
var est = $(this).val(); // read estimante
var count = $row.find('input[name="pcount[]"]').val(); // read count
$row.find('span.Amount').html(est*count); // put product

I have made following changes in your code, where in you are finding the first element inside the array. You will get the desired results
$('#EstmTotal').blur(function() {
$('.add_new_field').each(function() {
var elem = $($('#PCount')[0]).val();
var elem2 = $($('#EstmTotal')[0]).val();
$(this).find('#Amount').html(elem * elem2);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="add_new_field">
<div class="row">
<div class="col-md-4">
<div class="form-group">
<label class="col-form-label"> Enter Product Name</label>
<input type="text" class="form-control" name="pname[]" id="PName" placeholder="Product Name" />
</div>
</div>
<div class="col-md-4">

<input type="text" class="form-control" name="pcount[]" id="PCount" placeholder="No.Of Items" />

<!--<div class="col-md-1 removebtn"><i class="fa fa-remove"></i></div>-->
</div>
</div>

$('#EstmTotal').blur(function(){
$('.add_new_field').each(function() {
$(this).find('#Amount').html($('#PCount').val()*$('#EstmTotal').val());
});
});

I changed your code a bit. Now it checks on the blur event of both elements and it checks if both have a value. If both have it sets the calculated value. If not the div will me emptied.
Also parsing the value to a floating point number. You can change this to integers if you prefer that. The typing checking to number will be same for integers. I round the number down to 2 decimals, mainly to get around floating point number precision issues.
Last, since i thought you will have the ability to create more rows dynamically I made the blur event delegated by your .add_new_field element. This assumes your
.add_new_field is a static element. If not change this to the closest static parent of your row. For this I also changed some id selectors to class selectors because id's need to be unique.
$('.add_new_field').on('blur', '.EstmTotal, .PCount', function() {
$(this).closest('.row').each(function() {
var pcCount = parseFloat($(this).find('.PCount', this).val());
var estTotal = parseFloat($(this).find('.EstmTotal', this).val());
if (typeof pcCount === 'number' && pcCount && typeof estTotal === 'number' && estTotal) {
var calculatedValue = pcCount * estTotal;
calculatedValue = Math.round(calculatedValue * 100) / 100;
$(this).find('.Amount').text(calculatedValue);
} else {
$(this).find('.Amount').text('');
}
});
});
$('.add_another_product').on('click', function(){
$('.add_new_field').append($('.row').first().clone());
});

Dynamic forms with dynamic elements with related array index

Note: Newbie to javascript and PHP
Requirement:
User has the option to add multiple forms and multiple levels as shown in the image.
structure:
idnum = 0
next = 1;
dimandlevels = [{}];
$(document).on('click', '.addlevel', function() {
clickedIdnum = $(this).data('idnum');
//console.log(idnum+'\n');
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + clickedIdnum + next);
newTextBoxDiv.after().html('<input class="input form-control textboxclass" id="textbox' + next + '" name="dimdetail[' + idnum + '][2][' + next + ']" type="text" placeholder="Enter Level ' + (next + 1) + ' value ">');
newTextBoxDiv.appendTo(".TextBoxesGroup" + idnum);

Issue: 1. The add level works only on first form
2. And the array indexes should be proper
So i need a way such that i can create multiple dimensions with levels with proper level ids.
Thank you and sorry for my bad code !!!! I am very new to programming :/

JavaScript is the programming language of the Web.

create a "remove fields" button after new fields are dynamically added? - javascript

This should work for removing last child. function removeBandRow(){ var container = document.getElementById("newBandRows") var children = container.childNodes; container.removeChild(children[children.length - 1]); }
