Remove form input not working - javascript

I am having a problem removing an element from a form when a select input option is changed. When the select input is placed to "Manually Specify" the javascript correctly adds to the form as i would expect. When the option is changed again to anything other than "Manually Specify i would like it to remove the form inputs previously added, but can not seem to get this to work.
$(function() { /* DOM ready */
$("#distanceSelect").change(function() {
if ($(this).val() == "Manually Specify") {
var html = $("#distanceSpecifyInput").html();
$("#distanceSelectInput").after(html);
} else {
var child = document.getElementById("distanceSpecifyInput");
if (child) {
child.parentNode.removeChild(child);
}
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<form>
<div class="form-group row" id="distanceSelectInput">
<div class="col-sm-3">
<label for="distanceSelect" class="control-label">Distance:</label>
<select class="form-control" id="distanceSelect">
<option>5km</option>
<option>10km</option>
<option>Half Marathon</option>
<option>Marathon</option>
<option>Manually Specify</option>
</select>
</div>
</div>
<div class="hide" id="distanceSpecifyInput">
<div class="form-group row">
<div class="col-sm-1">
<input type="number" class="form-control" step="0.1" id="distance">
</div>

</div>
<div class="col-sm-1">

</div>
<div class="form-group">

</div>
</form>
</div>
Thanks for any help.


You should create a specific DIV to hold the content, rather than using .after(). That way you can clear it with .empty().
$(function() { /* DOM ready */
$("#distanceSelect").change(function() {
if ($(this).val() == "Manually Specify") {
var html = $("#distanceSpecifyInput").html();
$("#distanceOutput").html(html);
} else {
$("#distanceOutput").empty();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<form>
<div class="form-group row" id="distanceSelectInput">
<div class="col-sm-3">
<label for="distanceSelect" class="control-label">Distance:</label>
<select class="form-control" id="distanceSelect">
<option>5km</option>
<option>10km</option>
<option>Half Marathon</option>
<option>Marathon</option>
<option>Manually Specify</option>
</select>
</div>
</div>
<div class="hide" id="distanceSpecifyInput">
<div class="form-group row">
<div class="col-sm-1">
<input type="number" class="form-control" step="0.1" id="distance">
</div>
<div class="col-sm-2">
<select class="form-control" name="distanceFormat" id="distanceFormat">
<option>miles</option>
<option>km</option>
<option>meters</option>
</select>
</div>
</div>
</div>
<div id="distanceOutput">
</div>
<div class="form-group row">
<div class="col-sm-12">
<label for="hours" class="control-label">Desired Finish Time:</label>
</div>
<div class="col-sm-1">
<input type="number" class="form-control" required step="1" placeholder="hours" required name="hours" id="hours">
</div>
<div class="col-sm-1">
<input type="number" class="form-control" required step="1" placeholder="mins" required name="mins" id="mins">
</div>
<div class="col-sm-1">
<input type="number" class="form-control" required step="1" placeholder="secs" required name="secs" id="secs">
</div>
</div>
<div class="form-group">
<button type="button" class="btn btn-default" onclick="calculateRacePace()">Submit</button>
</div>
</form>
</div>
Note that copying the HTML like this results in duplicate IDs distance and distanceFormat. IDs are supposed to be unique, so you should fix up the IDs after copying.

I want to add the data of input fields and wanna show them in other input field

I have three input fields I want to get the sum of two input fields and put the result 3rd input field like this.
<div class="row mt-2">
<div class="col-md-2">
<label for="subTotal" class="form-label">SubTotal</label>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="subTotal" required>
</div>
</div>
<div class="row mt-2">
<div class="col-md-2">
<label for="discount" class="form-label">Discount</label>
</div>
<div class="col-md-2">

</div>
<div class="col-md-2">
<input type="number" class="form-control" id="discountResult">
</div>
</div>
In this code, I want to add the Subtotal value with discount value and show the result in the discount input text field.

I created a function below using your HTML.
It will take the value of subtotal and subtract the discount value onchange.
var subTotal = document.getElementById('subTotal');
var discount = document.getElementById('discount');
var discountResult = document.getElementById('discountResult');
discount.addEventListener("change", function() {
discountResult.value = subTotal.value - discount.value;
});
<div class="row mt-2">
<div class="col-md-2">
<label for="subTotal" class="form-label">SubTotal</label>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="subTotal" required>
</div>
</div>
<div class="row mt-2">
<div class="col-md-2">
<label for="discount" class="form-label">Discount</label>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="discount" required>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="discountResult">
</div>
</div>

<div class="row mt-2">
<div class="col-md-2">
<label for="subTotal" class="form-label">SubTotal</label>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="subTotal" required>
</div>
</div>
<div class="row mt-2">
<div class="col-md-2">
<label for="discount" class="form-label">Discount</label>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="discount" required>
</div>
<div class="col-md-2">
<input type="number" class="form-control" id="discountResult">
</div>
</div>
function sum()
{
var subTotal = document.getElementById("subTotal");
var discount = document.getElementById("discount");
var result=subTotal+discount;
document.getElementById("discountResult").value = result;
}

Since you're using HTML5 validation, use HTML5 DOM methods:
$(document).ready(function() {
// Add the e (event) argument to your event handler...
$("#saveBtn").on("click", function(e) {
// and call preventDefault() on it to prevent submission of the form.
e.preventDefault();
let allValid = true;
$("form").each(function (index, form) {
allValid = allValid && form.reportValidity();
});
if (allValid) {
/*$.ajax({
// ajax code to submit
}); */
}
});
});
form { border: 1px solid blue; }
input:invalid { border: 1px solid red; }

Things to note:
This will show the validation message on the last invalid field on the last form in document order.
I added CSS to highlight the form boundaries and invalid fields to make it more obvious.
The font element has been deprecated for a long time. Use a span and CSS.

Don't use HTML5 validation, instead create your own validation methods using Ajax to prevent client side user manipulation.
Using JavaScript to validate the forms before POST as follows:
<!--Html Form-->
<form name="contact-form" action="" method="post" onsubmit="return checkFields()">
<label for="nameinput">Name</label>
<input type="text" name="name">
<label for="emailinput">Email address</label>
<input type="email" name="email">
<label for="textarea-input">Message</label>
<textarea rows="5" name="message"></textarea>
<button type="submit" name="contactSubmitBtn">Submit</button>
</form>
function checkFields() {
var x = document.forms["example-form"]["name"].value;
var y = document.forms["example-form"]["email"].value;
var z = document.forms["example-form"]["message"].value;
if (x == "") {
Response Here
return false;
}
if (y == "") {
Response Here
return false;
}
if (z == "") {
Response Here!
return false;
}
}

<!--END OF TEMPLATE-->
and after that here is my jquery code
$("#add_more").click(function(e){
e.preventDefault();
$("#questions").append($("#questions_template").html());
})

First, add div for your template question, this is the one you will duplicate.
<form method="POST">
<div class="question">
.....
</div>
<button>submit</button>
<button>add_more</button>
</form>
Now use jquery to duplicate this 'question' and update it with correct id.
$("#add_more").click(function(e) {
e.preventDefault();
var id = $(".question").length;
id++;
var $newQuestion = $("form").find(".question:last").clone();
$newQuestion.find("label").attr("value", id);
$newQuestion.find("#question_no").text(id);
$newQuestion.insertBefore($(".btn-success"));
})

How to repeat a section on click?

I have this fiddle https://jsfiddle.net/74mh06v9/ where I am stuck on how to repeat the form group?
This code I am using is as below;
$(function () {
$(".repeat").on('click', function (e) {
e.preventDefault();
var $self = $(this);
$self.before($self.prev('table').clone());
});
});
My HTML is
<div class="col-md-12" class="repeatable">
<h4>Invoice Details </h4>
<table>
//various form groups here to repeat
</table>
<button class="repeat">Add Another</button>

First of all your html ws wrong inside table there should be td,tr etc but u placed div's i dont kno why. i hv corrected it
its working now.
HTML:
<div class="col-md-12" class="repeatable">
<div class="base-group" style="display:none;">
<h4>Invoice Details </h4>
<div class="col-sm-3">
<div class="form-group">
<label>Service User</label>
<div class="input-group">
<input name="service_user" id="service_user" class="form-control" type="text"></div>
</div>
</div>
<div class="col-sm-3">
<div class="form-group">

JS:
$(function() {
$(".repeat").on('click', function(e) {
var c = $('.base-group').clone();
c.removeClass('base-group').css('display','block').addClass("child-group");
$("#main-form").append(c);
});
});
fiddle https://jsfiddle.net/riazxrazor/74mh06v9/9/
if you want to try

Firslty, there is no need of table(no rows and columns), and replace table to div and add a class frm to it, then make a clone and append it.
$(function() {
$(".repeat").on('click', function(e) {
var frm =$('.frm:first').clone();
frm.find('input').val('');
$('.frm:last').after(frm);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-12 repeatable">
<div class="frm">
<h4>Invoice Details </h4>
<div class="col-sm-3">
<div class="form-group">
<label>Service User</label>
<div class="input-group">
<input name="service_user" id="service_user" class="form-control" type="text"></div>
</div>
</div>
<div class="col-sm-3">
<div class="form-group">
<label>Hours</label>
<div class="input-group">
<input name="total_hours" id="total_hours" class="form-control" type="text">

</div>
</div>
<div class="col-sm-3">
<div class="form-group">
<label>Rate</label>
<div class="input-group">

<button class="repeat">Add Another</button>

Slight changes to the answer above:
<script>
$(function () {
$(".repeat").on('click', function (e) {
e.preventDefault();
var clonedForm = $(".frm").clone();
clonedForm.appendTo("#table");
frm.find('input').val('');
});
});
</script>
<div class="col-md-12" class="repeatable">
<table id ="table">
<div class="frm">

<div class="col-sm-3">
<div class="form-group">

<div class="input-group">

</div>
</div>
<div class="col-sm-3">
<div class="form-group">
<label>Hours</label>
<div class="input-group">

<button class="repeat">Add Another</button>

Form submits even when i use prevent default on submit button click

what i want is that when i click on button "find reservation", the form submit should not refresh the page. Instead it should enable some fields in find reservation form underneath. But I am not able to achieve that. I am using bootstrap.
Here is my html part:-
<div class="container">
<div class="jumbotron checkInGuest">
<h3 class="h3Heading">Request for following information from guest</h3>
<form class="form-horizontal" id="checkInForm">
<div class="form-group">
<label for="reservationId" class="col-md-4">Reservation Id</label>
<div class="col-md-8">
<input type="text" class="form-control" id="reservationId" name="reservationId" required>
</div>
</div>
<div class="form-group">
<label for="dlNum" class="col-md-4">Driver License #</label>
<div class="col-md-8">
<input type="number" class="form-control" id="dlNum" min="0" name="dlNum" required>
</div>
</div>
<div class="form-group">
<div class="col-md-2">
<button type="submit" class="btn btn-success" id="findResButton">Find Reservation</button>
</div>
</div>
</form>
<!-- Form when info is found. Initially all fields are disabled-->
<div class="clear clearWithBorder"></div>
<h3 class="h3Heading">Information Found</h3>
<form class="form-horizontal">
<div class="form-group">
<label for="resId" class="col-md-3">Reservation Id</label>
<div class="col-md-3">
<input type="text" class="form-control" id="resId" name="resId" disabled>
</div>
<label for="dlNumReadOnly" class="col-md-3">Driver License #</label>
<div class="col-md-3">
<input type="number" class="form-control" id="dlNumReadOnly" min="0" name="dlNumReadOnly" disabled>
</div>
</div>
<div class="form-group">
<label for="guestFullName" class="col-md-3">Guest Full Name</label>
<div class="col-md-3">
<input type="text" class="form-control" id="guestFullName" name="guestFullName" disabled>
</div>
<label for="email" class="col-md-3">Email</label>
<div class="col-md-3">
<input type="email" class="form-control" id="email" name="email" disabled>
</div>
</div>
<div class="form-group">
<label for="numRooms" class="col-md-3">Rooms Booked</label>
<div class="col-md-3">
<input type="number" class="form-control readable" id="numRooms" name="numRooms" disabled>
</div>
<label for="roomType" class="col-md-1">Room Type</label>
<div class=" col-md-2">
<label for="smoking">
<input type="radio" name="roomType" id="smoking" class="roomType readable" disabled> Smoking
</label>
</div>
<div class=" col-md-3">
<label for="nonSmoking">
<input type="radio" name="roomType" id="nonSmoking" class="roomType readable" disabled>Non-Smoking
</label>
</div>
</div>
<div class="form-group">
<label for="discount" class="col-md-3">Discount</label>
<div class="col-md-3">
<select class="form-control readable" id="discount" disabled>
<option selected>0%</option>
<option>10%</option>
<option>20%</option>
<option>30%</option>
</select>
</div>
<label for="checkInDate" class="col-md-3">CheckIn Date</label>
<div class="col-md-3">
<input type="date" class="form-control readable" id="checkInDate" name="checkInDate" disabled>
</div>
</div>
<div class="form-group">
<label for="checkOutDate" class="col-md-3">CheckOut Date</label>
<div class="col-md-9">
<input type="date" class="form-control readable" id="checkOutDate" name="checkInDate" disabled>
</div>
</div>
<div class="form-group">
<div class="col-md-2">
<button type="button" class="btn btn-success" id="roomOrdButton">Confirm Room Order</button>
</div>
</div>
</form>
<div class="clear clearWithBorder"></div>
<h3 class="h3Heading">Final Room Order</h3>
<form class="form-horizontal">
<div class="form-group">
<label for="perInEachRoom" class="col-md-12">Number of people in each room</label>
<div class="col-md-8 " id="perInEachRoom">
</div>
<div class="form-group">
<div class="col-md-2">
<button type="button" class="btn btn-success" id="checkInButton">Check In</button>
</div>
</div>
</div>
</form>
</div>
</div>
And this is jquery part:-
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="js/jquery.validate.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script>
$("#checkInForm").validator();
$("#findResButton").click(function(e){
e.preventDefault();
$(".readable").prop("disabled",false);
});
$("#roomOrdButton").click(function(){
var numberOfRooms=$("#numRooms").val();
var counter=0;
var container=$('<div/>');
$(".readable").prop("disabled",true);
for(counter=1;counter<=numberOfRooms;counter++){
container.append('<label for="room">Room '+counter+'</label><input type="number" class="form-control readable" name="checkInDate" />');
}
$("#perInEachRoom").html(container);
});
$("#checkInButton").click(function(){
$("#perInEachRoom").html("");
});
</script>

You need to put your code in a document.ready() function, so:
$(document).ready(function() {
$("#checkInForm").validator();
$("#findResButton").click(function(e){
e.preventDefault();
$(".readable").prop("disabled",false);
});
$("#roomOrdButton").click(function(){
var numberOfRooms=$("#numRooms").val();
var counter=0;
var container=$('<div/>');
$(".readable").prop("disabled",true);
for(counter=1;counter<=numberOfRooms;counter++){
container.append('<label for="room">Room '+counter+'</label><input type="number" class="form-control readable" name="checkInDate" />');
}
$("#perInEachRoom").html(container);
});
$("#checkInButton").click(function(){
$("#perInEachRoom").html("");
});
});
You should also have a look at this question: Form is submitted when I click on the button in form. How to avoid this?
Long story short, you should use
<button type="button"...
not
<button type="submit"...

Actually, all I did is:-
$("#checkInForm").submit(function(e)
{
e.preventDefault();
});
And that solved it. I didnt have to change button type or anything. Basically, in future when I will make AJAX calls I will have the code underneath preventDefault statement.
