How to implement previously declared jquery.validate rules on dynamically added form fields [duplicate]

This question already has answers here:
Validate dynamic field jquery
(2 answers)
Closed 2 years ago.
I have to clone the certain section of form and have to implement same validation rules defined previously.
As I researched on this issue, almost all them recommended to add new rules again in the newly generated elements. So, I had tried by adding new rule with following code
let $contactItem = $(".contact")
.first()
.clone()
.insertAfter($(".contact").last());
$contactItem.find("input").each(function(){
$(this).rules("add", {
required : true,
messages : { required : 'field is required.' }
});
});
But my bad luck, this technique did not solve my issue. So I am looking for another solution for it.
Some details on library I am using:
jQuery v1.9.1
jQuery Validation Plugin v1.17.0
$(document).ready(function() {
let $validator;
$("#btnAddNew")
.off("click")
.on("click", function() {
let $contactItem = $(".contact")
.first()
.clone()
.insertAfter($(".contact").last());
});
$validator = $("#contactForm").validate({
rules: {
firstName: {
required: true
},
lastName: {
required: true
}
},
messages: {
firstName: {
required: "* Required"
},
lastName: {
required: "* Required"
}
},
ignore: ":hidden, :disabled"
});
$("#btnSave")
.off("click")
.on("click", function() {
if ($validator.form()) {
console.log("ok");
}
});
});

Just adding required to the elements is probably the simplest solution and modify the default message.
I've also commented out an approach for setting class rules.
Note you also need to modify the names in order for them to be unique. I've used very simple incremental logic , modify if you will be adding and removing
$.extend($.validator.messages, {
required: "* required."
})
// Alternate using class rules
/*jQuery.validator.addClassRules("name-field", {
required: true
});*/
$(document).ready(function() {
let $validator;
$("#btnAddNew")
.off("click")
.on("click", function() {
let $contact = $(".contact");
let $contactItem = $contact
.first()
.clone()
.insertAfter($(".contact").last());
// increment input names
$contactItem.find('input').attr('name', function(_, curr) {
return curr + $contact.length
});
});
$validator = $("#contactForm").validate();
$("#btnSave")
.off("click")
.on("click", function() {
if ($validator.form()) {
console.log("ok");
}
});

Jquery validator moves input field

I've got three fields inline and one of them is a inpt field, this is how it look like when they are validated
https://ibb.co/X8c1jDZ
the problem is when I enter some values into the input fiedl then it moves all the other fields as you can see from the image
https://ibb.co/Fn666cw
I believe something is wrong with the way I unhighlight the field once has been filled but not sure, maybe someone can help me. Please let me know if you need more details. many thanks

This is my javascript code
form.validate({
// doNotHideMessage: true, //this option enables to show the error/success messages on tab switch.

},

},
errorPlacement: function(error, element) { // render error placement for each input type
if (element.parent(".input-group").length > 0) {
error.insertAfter(element.parent(".input-group"));
} else {
error.appendTo(element.closest('.form-group'));
}
},
invalidHandler: function(event, validator) { //display error alert on form submit
success.hide();
error.show();
App.scrollTo(error, -200);
},
highlight: function(element) { // hightlight error inputs
$(element).closest('.form-group').removeClass('has-success').addClass('has-error');
},
unhighlight: function(element) { // revert the change done by hightlight

},
success: function(label) {
label.addClass('valid').closest('.form-group').removeClass('has-error').addClass('has-success'); // set success class to the control group
},
This is how i clone the fields
//add more fields group
var fieldGroup = $(".fieldGroup").clone();
// Hide remove button
$(".remove").parent('span').hide();
$(".addMore").click(function(e) {
var fgc = $('body').find('.fieldGroup').length;
var fieldHTML = '<div class="form-group fieldGroup">' + fieldGroup.html() + '</div>';
fieldHTML = fieldHTML.replace('kmg_admin_new_building_owner_type-1', 'kmg_admin_new_building_owner_type-' + (fgc + 1));
fieldHTML = fieldHTML.replace('kmg_admin_new_building_owner-1', 'kmg_admin_new_building_owner-' + (fgc + 1));
fieldHTML = fieldHTML.replace('kmg_admin_new_building_owner_quota-1', 'fkmg_admin_new_building_owner_quota-' + (fgc + 1));
$('body').find('.fieldGroup:last').after(fieldHTML);
var el = $('.fieldGroup').next();
// Hide add new button
el.find('.addMore').parent('span').hide();
// Show remove button
el.find('.remove').parent('span').show();
// Load selectpicker again after cloning the inputs
$('.bs-select').selectpicker({
iconBase: 'fa',
tickIcon: 'fa-check',
dropupAuto: false
});
});
//remove fields group
$("body").on("click", ".remove", function() {
$(this).parents(".fieldGroup").remove();
});

This is not a serious problem, I think, you just have to think of the changes of the layout, and prepare for them in your CSS.
Here's an example of what's happening:
(You can find a short explanation at the bottom of the answer.)
jQuery(document).ready(function($) {
$(".modify").on('click', function(e) {
// $.fn.toggle() switches between display: none and
// display: block
$('#il3').find('label').toggle()
})
})
.inputandlabel {
float: left;
}
input[type="text"],
label {
display: block;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<div class="container">
<div class="row">
<div class="col-6">
<button type="button" class="btn btn-primary modify">Just push it to see the problem</button>
</div>
</div>
<div class="row">
<div class="col-12">
<div id="il1" class="inputandlabel">
<label for="form1">Form1</label>
<input id="form1" type="text" />
</div>
<div id="il2" class="inputandlabel">
<label for="form2">Form2</label>
<input id="form2" type="text" />
</div>
<div id="il3" class="inputandlabel">
<label for="form3">Form3</label>
<input id="form3" type="text" />
</div>
<div id="il4" class="inputandlabel">
<label for="form4">Form4</label>
<input id="form4" type="text" />
</div>
<div id="il5" class="inputandlabel">
<label for="form5">Form5</label>
<input id="form5" type="text" />
</div>
<div id="il6" class="inputandlabel">
<label for="form6">Form6</label>
<input id="form6" type="text" />
</div>
</div>
</div>
</div>
And here's a solution:
jQuery(document).ready(function($) {
$(".modify").on('click', function(e) {
e.preventDefault()
if ($('#il3').find('label').css('visibility') !== 'hidden') {
$('#il3').find('label').css('visibility', 'hidden')
} else {
$('#il3').find('label').css('visibility', 'visible')
}
})
})
.inputandlabel {
float: left;
}
input[type="text"],
label {
display: block;
}

<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<div class="container">
<div class="row">
<div class="col-6">
<button type="button" class="btn btn-primary modify">Just push it to see "nothing"</button>
</div>
</div>
<div class="row">
<div class="col-12">
<div id="il1" class="inputandlabel">
<label for="form1">Form1</label>
<input id="form1" type="text" />
</div>
<div id="il2" class="inputandlabel">
<label for="form2">Form2</label>
<input id="form2" type="text" />
</div>
<div id="il3" class="inputandlabel">
<label for="form3">Form3</label>
<input id="form3" type="text" />
</div>
<div id="il4" class="inputandlabel">
<label for="form4">Form4</label>
<input id="form4" type="text" />
</div>
<div id="il5" class="inputandlabel">
<label for="form5">Form5</label>
<input id="form5" type="text" />
</div>
<div id="il6" class="inputandlabel">
<label for="form6">Form6</label>
<input id="form6" type="text" />
</div>
</div>
</div>
</div>
You can see from the two snippets, that by setting display: none; on the label scrambles the layout. display: none; takes the element out of the flow (not the DOM itself, but from the object flow), while visibility: hidden; just makes the element invisible. Quite a difference, isn't it?
So, setting the display CSS property to none "removes the height" that kept your layout in order - try setting the elements visibility to hidden with JS.
If that's not working, then give the form-group a fixed height (the height with success / error message), and don't change that value on success / error.

Hidden input not submitted after updating value in on submit event

Using Laravel framework.
I don't get it. I have a hidden input with id = prime near the top.
<form name="paymentForm" action="/parking_302/upload_payment" method="POST" role="form" class="form-horizontal">
{{ csrf_field() }}
<input type="hidden" id="parking_lot_id" name="parking_lot_id" value="{{ $parking_lot_id }}">
<input type="hidden" id="booking_id" name="booking_id" value="{{ $booking_id }}">
<input type="hidden" id="Price" name="Price" value="{{ $Price }}">
<input type="hidden" id="prime" name="prime"> {{-- To be obtained --}}

</div>
</div>
</form>
I then have a on submit event which does a few things. At the bottom is me updating the hidden input with id = prime.
$('form').on('submit', function (event) {
//Code for first part of form begin
var boolFlag = true; //Default is submit
var errorMsg = ""; //Initial message
//Begin validation
var numOfNonEmptyFields = 0;
if(document.forms["paymentForm"]["CustomerEmail"].value != "") {
numOfNonEmptyFields++;
}
if(document.forms["paymentForm"]["CustomerPhone"].value != "") {
numOfNonEmptyFields++;
}
if(numOfNonEmptyFields == 0) {
errorMsg += "請輸入至少一個電子信箱或手機號碼.\n";
boolFlag = false;
}
//End validation
//Final steps: overall error message + success or fail case
if(boolFlag == false) {
alert("錯誤:\n" + errorMsg);
return false;
}
//Code for first part of form end
// fix keyboard issue in iOS device
forceBlurIos()
const tappayStatus = TPDirect.card.getTappayFieldsStatus()
console.log(tappayStatus)
// Check TPDirect.card.getTappayFieldsStatus().canGetPrime before TPDirect.card.getPrime
if (tappayStatus.canGetPrime === false) {
bootbox.alert({
title: "錯誤訊息",
message: "取得不了Prime.",
buttons: {
ok: {
label: "OK",
className: "btn btn-primary"
}
}
});
return false
}
// Get prime
TPDirect.card.getPrime(function (result) {
if (result.status !== 0) {
bootbox.alert({
title: "錯誤訊息",
message: result.msg,
buttons: {
ok: {
label: "OK",
className: "btn btn-primary"
}
}
});
return false
}
$("#prime").val(result.card.prime);
})
})
I've tested the hidden input with alert($("#prime").val()) directly after and it seems updated, however after submission, my Controller receives the value as null while other hidden input values are correct. So I suspect it's something got to do with the on submit event.

Added id attribute to the form element:
<form id="paymentForm" name="paymentForm" action="/parking_302/upload_payment" method="POST" role="form" class="form-horizontal">
Removed type from the button and added id:
<button id="submit-btn" class="btn btn-default">Pay</button>
Introduced a new click listener:
$(document).on("click","#submit-btn", function(event){
event.preventDefault();
validateAndSendForm();
});
Introduced a new function for the final form submit:
function submitForm(){
//do other stuff here with the finalized form and data
//.....
$( "#paymentForm" ).submit();
}
And put all of your old things into a new function as well:
function validateForm(){
//Code for first part of form begin
var boolFlag = true; //Default is submit
var errorMsg = ""; //Initial message
...
...
...
}
// Get prime
TPDirect.card.getPrime(function (result) {
if (result.status !== 0) {
bootbox.alert({
title: "錯誤訊息",
message: result.msg,
buttons: {
ok: {
label: "OK",
className: "btn btn-primary"
}
}
});
return false;
}
$("#prime").val(result.card.prime);
//use when you are ready to submit
submitForm();
})
}
So, basically you will have a "submitForm" function that you can use whenever you are ready to submit the form.

Seems like TPDirect.card.getPrime is something that gets data asynchronously so the $('form').on('submit' function won't wait for it to finish.

Trying to send custom inputs to braintree but only payment_method_nonce works

I am attempting to have the user inputs( first name, last name, contract number, amount) pass to payment.php and then be sent via $result = Braintree_Transaction::sale but payment_method_nonce is the only thing that passes to payment.php.

Remember when you collect form data on your server, you need to reference those inputs by their name attribute. Once you add the respective name values to each of these inputs, it should work as expected.
For example, your first name input;
<input type="text" placeholder="John" class="form-control" id="first-name" name="first-name">

jQuery ajax form submission to php not working with response from server

Note: this is a jQuery coding exercise and I am not allowed to use plugins or other modules.
I have a typical signup form. When the user completes registration and everything is valid I want to fade in a sign in element that the user can use to sign in right away.
Note: I am using the Skeleton framework
HTML:
<div class="container">
<form id="myForm" action="validate_signup.php" method="post">
<div class="row">
<div class="twelve columns">
<h3 class="center">Sign Up</h3>
</div>
</div><!--end row-->
<div class="row">
<div class="four columns offset-by-four">
<input class="u-full-width" type="email" placeholder="Email" id="email" name="email">
<span class="error">Email not entered</span>
</div>
</div><!--end row-->
<div class="row">
<div class="four columns offset-by-four">
<input class="u-full-width" type="password" placeholder="Password" id="pword" name="pword">
<span class="error">Password not entered</span>
</div>
</div><!--end row-->
<div class="row">
<div class="four columns offset-by-four">
<input class="u-full-width" type="text" placeholder="First Name" id="fname" name="fname">
<span class="error">First Name not entered</span>
</div>
</div><!--end row-->
<div class="row">
<div class="four columns offset-by-four">
<input class="u-full-width" type="text" placeholder="Last Name" id="lname" name="lname">
<span class="error">Last Name not entered</span>
</div>
</div><!--end row-->
<div class="row">
<div class="six columns offset-by-four">
<input class="button-primary" type="submit" value="Submit" name="signup">
</div>
</div><!--end row-->
</form>
<div class="row">
<div class="twelve columns">
<p id="response" class="center no-display"></p>
</div>
</div>
</div><!--end container-->
<script src="../js/jquery.js"></script>

jQuery:
// jQuery form validation
$(document).ready(function(){
// field mapping
var form_fields = {
'email' : 'email',
'pword' : 'password',
'fname' : 'first name',
'lname' : 'last name'
};
// ajax data
var ajaxData = {};
// make sure form fields were entered
$('#myForm').on('submit', function() {
for (var field in form_fields) {
if (!$('#' + field).val()) {
$('#' + field).next().addClass('error_show');
} else if ($('#' + field).val()) {
$('#' + field).next().removeClass('error_show');
ajaxData[field] = $('#' + field).val();
}
}
// 'signup' post field to indicate to php a submission was made
ajaxData['signup'] = 'Submit';
// send data if it is all there
if (Object.keys(ajaxData).length === 5) {
$('#response').hide().empty();
var request = $.ajax({
url : 'validate_signup.php',
method : 'POST',
data : ajaxData,
dataType : 'html'
});
request.done(function(response) {
if (response === 'Sign up complete.') {
$('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn();
}
$('#response').html(response).fadeIn();
$("input[name=email], input[name=pword], input[name=fname], input[name=lname]").val('');
});
request.fail(function() {
alert('Your request could not be processed.');
});
}
return false;
});
});
I am not going to post the php as it is a big piece of code. Just know that if all user data is valid and a successful registration is made PHP outputs, Sign up complete. That is the response.
The main line in question is:
if (response === 'Sign up complete.') {
$('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn();
}
First I tested this condition with console.log('response was Sign up complete) in place of $('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn(); to make sure the condition worked, which it did. But, the fading in of a signin.php link does not work. Instead I am only seeing,
Sign up complete.

change this line
if (response === 'Sign up complete.') {
$('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn();
}
$('#response').html(response).fadeIn();
to
if (response === 'Sign up complete.') {
$('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn();
}else{
$('#response').html(response).fadeIn();
}
Your can also change the div style to see the fadein effect. example:
<div id="response" style="display:none">
Use time parameter to see the real effect.
$('#response').html(response + "<a href='signin.php'>Sign in</a>").fadeIn(1000);
