Why am I getting null values when submitting a form after editing some values with JS?

I have a form with some inputs that are filled from the result of an AJAX request. When I submit the form I get only null on the back-end. I tried to submit the values without editing it and it works
this is my java script code
editPayment = function() {
if ($('#entrytransId').val() != '') {
if ($('#entryReceiptTypesselect').val() == "1") {
$.ajax({
type: "GET",
url: "#Url.Action("GetInvoiceNumber", "Payment")",
data: {transId: $('#entrytransId').val()},
success: function(response) {
if (response.invNo == 0) {
window.location.reload();
} else {
$('#reciptNo').val(response.invNo);
$('#enteryAmt').val(response.Amt);
$('#entrytransId').attr("disabled", "true");
$('#enteryhide').show(500);
}
},
error: function(reponse) {
window.location.reload();
}
});
}
}
This is Exactly My HTML Form with inputs I have tried more times and its failures
but when I deleted the javascript function and fill the data manually its works
<form action="/Payment/EditPayment" id="MF" method="post">

The issue is not with setting the values via javascript/jquery, but specifically with setting the inputs to disabled.
$('#entrytransId').attr("disabled", "true");
when an input is set to disabled, it is not included (it is excluded) from the form's POST, so will appear as null in the server-side code.
You can:
- not set them to disabled (will affect your UX)
- enable them just before POST (icky)
- use hidden fields
MVC does this for checkboxes, so you can copy that idea here:
<input type='text' name='entryid' />
<input type='hidden' name='entryid' />
POST uses the input's name field, not its id, so it's ok to have multiple inputs with the same name.
POST will then use the first input that is not disabled (so don't put the hidden one first...)
Then just update the jquery to apply the value to both inputs (if you also want it shown in the UI) rather than by id, eg:
$("name[entryid]").each(function() { $(this).val(newvalue); });
(other ways to set this may be better, not checked if .val() will apply to all, likely only applies to the first)

The proplem was on $('#entrytransId').attr("disabled", "true");
i have another function onselectChange() is disabled all inputs , i tried $('#entrytransId').attr("disabled", "true"); and its works well

Undefined value set by previous Jquery event

I am trying to post a form with dynamic set value on click event by getting undefined respose Here is my code.
$( ".paymentselect" ).click(function() {
var bookingid=$(this).data('id');
$('#paymentstats').css('display','block');
$('#paymentform').attr('action', document.location.origin +"/accounts/" + bookingid);
});
$('#paymentform').submit(function(event){
event.preventDefault();
var data=$('#paymentform').serialize();
$.ajax({
url: $(this).attr('action'),
method: 'POST',
data: data,
beforeSend: function() {
// setting a timeout
$('#wait').html('<i class="material-icons">cached</i>');
},
success: function(data){
if(data.status){
$('#paymentstats').css('display','none');
alert("UPDATED");
//location.reload();
}else
{
alert("something went wrong");
}
}
});
});
On POST bookingid is Undefind. Little Help will be appriciated

As requested Above is my html Code As requested.
I ALREADY TRIED SETTING bookingpaymentid Val on click event But It Also shows Undefined when Form is POST On the Server.
I just figured out that value become undefined when i post form . Any Suggestion

Because you declare bookingid inside $( ".paymentselect" ).click(function() {.
You can try this:
var bookingid = null;
$( ".paymentselect" ).click(function() {
bookingid=$(this).data('id');
$('#paymentstats').css('display','block');
$('#paymentform').attr('action', document.location.origin +"/accounts/" + bookingid);
});

In plunker bookingid is not undefined. Go to plunker address and check browser console to see variable's values.
You might be having trouble to load order of your scripts file. As you can see in plunker make sure to load your js codes end of the body tag.

jQuery and Ajax not working $.on

I want when I click on Clear button, all fields in the form to be cleared.
The ajax request is only replacing the form from the tag <form> to </form>.
When it is clicked on Clear button, the console output is working.
I have the following form:
<div class="col-lg-5 formWrapper">
<form data-th-fragment="layoutForm" id="layoutForm" class="form-horizontal" data-th-object="${layout}" data-th-action="#{/layouts/add}" method="POST" role="form">
<div class="row">
<input id="objectId" data-th-field="*{id}" type="hidden">
<input data-th-if="*{filePath} !=null" data-th-field="*{filePath}" type="text" hidden="hidden">
<label for="layoutName" >Layout name</label>
<input data-th-field="*{name}" id="layoutName" class="form-control" type="text">
</div>
<div class="row">
<div class="col-lg-4">
<label for="status">Status</label>
<select id="status" data-th-field="*{status}"class="form-control">
<option value="1">Active</option>
<option value="0">Blocked</option>
</select>
</div>
<div class="col-lg-6">
<label for="exhibitorName">Exhibitor</label>
<select data-th-field="*{exhibitor}" name="exhibitorName" id="exhibitorName" class="form-control">
<option data-th-each="exhibitor : ${exhibitorsList}" data-th-value="${exhibitor.id}" data-th-text="${exhibitor.exhibitorName}"></option>
</select>
</div>
</div>
<div class="row">
<div class=" col-lg-3">
<input id="clearForm" type="reset" value="Clear" class="form-control btn-lg btn btn-default">
</div>
<div class=" col-lg-3 col-lg-offset-4">
<input id="submitButton" type="submit" value="Add" class="form-control btn-lg btn btn-success">
</div>
</div>
</form>
</div>
The form looks something like this:
The jQuery is as follow:
$(document).ready(function() {
$('.formWrapper').on('click','#clearForm', function (event) {
$(this).closest('form').find("input[type=text]").val("");
console.log("ASD");
});
});
The snipped is how I replace the form:
$("body").on('click','#editLayout', function(event){
var ajax = $.ajax({
url : "/layouts/edit/" + $(this).data("id"),
dataType : "html",
success: function (data) {
$("#layoutForm").replaceWith(data);
$('#submitButton').val('Edit').addClass('btn-warning').removeClass('btn-success');
}
});
});

Try this,
$('#form_id').trigger("reset");
or
$('#form_id')[0].reset();
A reset button doesn't need any script at all (or name or id):
<input type="reset">
and you're done. But if you really must use a script, note that every form control has a form property that references the form it's in, so you could do:
<input type="button" onclick="this.form.reset();">
But a reset button is a far better choice.

Try to use $('#clearForm').reset(); or $('#clearForm')[0].reset();

Stop my form moving on error

Why does my form shift down and a little to the right when validate.js displays an error? I just can't figure it out and where I can adjust this. I am using bootstrap. I'd really appreciate any help. Thanks.
The jquery
$(document).ready(function(){
$("#message").hide();
//Define your validation rules.
$("#bill_cost").validate({
expression: "if (!isNaN(VAL) && VAL) return true; else return false;",
message: "error"
});
//Define the event that will occur when the entire form is validated (on form submission)
$('#myform').validated(function(){
var formdata = $('#myform').serialize();
//Post form data
$.post('../php_includes/insert.php', formdata, function(data){
//Process post response
$("#message").html(data);
$("#message").fadeIn(500);
$("#message").fadeOut(500);
});
//Reset Form
$('#myform')[0].reset();
});
});
This is the form
<form class="form-inline" action="" id="myform" method="post">
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="bill_cost"></label>
<div class="col-md-8">
<input id="bill_cost" name="bill_cost" type="text" placeholder="Bill Cost" class="form-control input-lg" required>
</div>
</div>
<!-- Button -->
<div class="form-group">
<label class="col-md-4 control-label" for="submit1"></label>
<div class="col-md-4">
<button type="submit" id="submitButtonId" name="submit1" class="btn btn-primary btn-xl">Submit</button>
</div>
</div>
</form>

Ajax call is not working?

Hi i am trying to submit a form in bootstrap modal. This modal is going to open based on a href click event. This a href tag is going to b generated dynamically in ajax call using Jquery.
format of the a href tag is below to call bootstrap modal.
'<a id="addvideo" data-toggle="modal" data-title="'+field.title+'" data-id="'+field.video_id+'" data-desc="'+field.description+'" data-channelname="'+field.channel_name+'" data-yudate="'+field.created_date+'" href="#form-content">'+field.title+'</a>'
The modal which i am calling is below shown.
<div id="form-content" class="modal hide fade in" style="display: none;">

Now to call modal based on click i am using below javascript code and in this code only i am passing data to modal by setting text boxes values in modal using Jquery like below.
$(document).on("click", "#addvideo", function () {
var videoid = $(this).data('id');
var videotitle = $(this).data('title');
var videodesc = $(this).data('desc');
var channelname = $(this).data('channelname');
var yudate = $(this).data('yudate');
$(".modal-body #videoid").val( videoid );
$(".modal-body #videotitle").val( videotitle );
$(".modal-body #videodesc").val( videodesc );
$(".modal-body #channelname").val( channelname );
$(".modal-body #yudate").val( yudate );
});
Ajax call function is below one.
$(document).ready(function(e) {
$('input#submit').click(function() {
var title = $('#videotitle').val();
var videoid = $('#videoid').val();
var description = $('#videodesc').val();
var channel = $('#channelname').val();
var actors = $('#actors').val();
var directors = $('#directors').val();
var producers = $('#producers').val();
var musicians = $('#musicians').val();
var cast = $('#cast').val();
var yudate = $('#yudate').val();
var orderno = 0;
if($("#orderno").is(':checked'))
{
var orderno = 1;
}
var hidevideo = 0;
if($("#hidevideo").is(':checked'))
{
var hidevideo = 1;
}
var postdata = "title="+title+"&videoid="+videoid+"&description="+description+"&channel="+channel+"&actors="+actors+"&directors="+directors+"&producers="+producers+"&musicians="+musicians+"&cast="+cast+"&orderno="+orderno+"&hidevideo="+hidevideo+"&yudate="+yudate;
$.ajax({
type: 'POST',
url: 'addvideo.php',
data: "title="+title+"&videoid="+videoid+"&description="+description+"&channel="+channel+"&actors="+actors+"&directors="+directors+"&producers="+producers+"&musicians="+musicians+"&cast="+cast+"&orderno="+orderno+"&hidevideo="+hidevideo+"&yudate="+yudate,
datatype:'json',
success: function(response) {
$("#form-content").modal('hide');
alert(response);
},error: function(){
alert("video categorization failed");
}
});
});
});
Now my modal is loading fine and values are showing up in assigned text boxes once the modal loaded on click on href tag. But after click on submit it is redirecting to the same php url and all the parameters are adding as query parameters and weird thing is if i open modal second time and try to submit ajax call is working.

$('input#submit').click(function(e) {
e.preventDefault();//
.....rest of the code here
});
if the form elements are loaded dynamically then try delegating click
$(document).on("click", "#submit", function (e) {
e.preventDefault();
});

try using following tested and workinf code for AJAX call
// Get the form data. This serializes the entire form. pritty easy huh!
var form = new FormData($('#form_step4')[0]);
$.ajax({
type: "POST",
url: "savedata.php",
data: form,
cache: false,
contentType: false,
processData: false,
success: function(data){
//alert("---"+data);
alert("Settings has been updated successfully.");
window.location.reload(true);
}
});
You need to load jQuery for this.
