On change attribut is not initialised in thymeleaf

I have the following problem with javascript integrated into thymeleaf template.
I have the following table with different input fields which are filled up with data from a model.
Furthermore i have for each of this input field a hidden additional input field.
Idea is that when I change not hidden input tag, the hidden ones will receive the new value
<tr th:each=" item : ${products}">
<td>
<input class="form-control" type="text" th:value="${item.product.name}" id="productName" name="productName" />
</td>
<td>
<input class="form-control" type="text" th:value="${{item.product.price}}" id="productPrice" name="productPrice" />
</td>
<td>
<input class="form-control" type="text" th:onchange="substituteOnClick()" th:value="${item.quantity}" id="quantityItem" name="quantityItem" />
</td>
<td>
<input class="form-control" type="text" th:value="${item.MinQuantity}" th:onchange="substituteOnClick()" id="minquantityItem" name="minquantityItem" />
</td>
<td>
<form th:action="#{/deleteWarehouseItem/{id_del}/(id_del=${item.id})}" method="post" role="form" class="ui form">
<button type="submit" class="ui form" name = "itemDel" th:value="${item.id}">Löschen</button>
</form>
</td>
<td>
<form class="ui form" method="post" th:action="#{/updateItem}" >
<input type="hidden" name="productName_mvc" id="productName_mvc" value="0" th:value="${item.product.name}"/>
<input type="hidden" name="productPrice_mvc" id="productPrice_mvc" value="0" th:value="${{item.product.price}}"/>
<input type="hidden" name="quantityItem_mvc" id="quantityItem_mvc" value="0" th:value="${item.quantity}"/>
<input name="minquantityItem_mvc" id="minquantityItem_mvc" value="0" />
<input type="hidden" name="inventoryIdentifier_mvc" id="inventoryIdentifier_mvc" th:value="${item.id}"/>
<button type="submit" class="ui labeled icon button" name = "updateItem" th:text="#{management.updateItem}">
</button>
</form>
</td>
</tr>
Here is my javascript file
function substituteOnClick() {
var pN=document.getElementById("productName").value;
var pP=document.getElementById("productPrice").value;
var qI=document.getElementById("quantityItem").value;
var MqI=document.getElementById("minquantityItem").value;
document.getElementById("productName_mvc").value=pN;
document.getElementById("productPrice_mvc").value=pP;
document.getElementById("quantityItem_mvc").value=qI;
document.getElementById("minquantityItem_mvc").value=MqI;
}
As you see my problem is that for each row I need 2 buttons for different actions, since that I decided that It would be useful just to change values of hidden inputs. It is possible because I use hidden inputs only if I need to update an object and it happens mainly on change event. But my problem is that even if I write anything new in not hidden inputs, it does not influence my hidden ones. I have cheked it by not hidding one of them.
How is it possible to change values in other inputs by changing them firstly in other ones.
Best wishes

first of all, you need to remove these extra brackets from this line
<input class="form-control" type="text" th:value="${{item.product.price}}" id="productPrice" name="productPrice" />
and then in your javascript use console.log() to check whether on onchange event its fetching the change value or not like
console.log("In js function");
console.log(qI);
if you are not getting these values then Instead of onchange event add a button for each input or for all input use a single button inside form and then use the onClick function or onsubmit like this:
<form onsubmit="return substituteOnClick()">
<td>
<input class="form-control" type="text" th:value="${item.product.name}" id="productName" name="productName" />
</td>
<td>
<input class="form-control" type="text" th:value="${item.product.price}" id="productPrice" name="productPrice" />
</td>
<td>
<input class="form-control" type="text" th:value="${item.quantity}" id="quantityItem" name="quantityItem" />
</td>
<td>
<input class="form-control" type="text" th:value="${item.MinQuantity}" id="minquantityItem" name="minquantityItem" />
</td>
<input type="submit" name="Submit" value="Submit"/>
</form>
Let me know if this helps

Can't get input value from laravel contoller

I update input with id='total' with event onchange. When I fill quantity input, the input total is updated with correct value but when i try to get the value from controller, it returns null. Any idea? Thanks
This is the code:
<div class="form-group" >
<input type="text" name="quantity" class="form-control" id="quantity" onchange="updateInput(this.value)" >
</div>
</td>
<td align="center">
<div class="form-group ">
<input type="text" class="form-control" id="total" name="total" value="" disabled >
</div>
</td>
And this is function onchange
function updateInput(x)
{
var price=parseFloat(document.getElementById('price').value);
document.getElementById('total').value=parseFloat(x)*price;
}

Solved it, just removed disabled attribute and it works.

Using JQuery on changing sibling input of the same div group only

So I've been working on a code that would try to pre-fill some disabled inputs with a keyup() function from another enabled input that are all enclosed in one div element. What happens is that upon key release, it tries to change the value of the disabled inputs from that specific row of divs. Here's what I currently have on my code
<div class="container-fluid" id="clonegrp">
<div class="row grpit">
<div class="col-md-7">
<input type="text" name="it[]" class="form-control" id="item" placeholder="Chemical/Equipment*" required="true">
</div>
<div class="col-md-2">
<input type="text" name="amount[]" class="form-control" placeholder="Amount*" required="true">
</div>
/<div class="col-md-1">
<input type="text" class="form-control" id="max" placeholder="Max" readonly="readonly">
</div>
<div class="col-md-1">
<input type="text" class="form-control" id="unit" placeholder="Unit" readonly="readonly">
</div>
</div>
so this group of inputs can be cloned by some button and through this JQuery code
var $button2=$('#add-item'),
$row2=$('.grpit').clone(),
$try2=$('#clonegrp');
$button2.click(function() {
$row2.clone().appendTo($try2);
});
the problem lies at the part where I try to do the live keyup function
$(document).ready(function() {
$('#clonegrp').on('keyup','#item', function() {
$('#max').val('some text');
});
});
I know that this is wrong since the id part would mess up which of the cloned inputs with the #max id gets to change the input. I can't seem to figure out how to get the #max sibling of the currently focused #item input. How do I do that?

jquery how to detect current input id

screenshoot : http://www.imagebam.com/image/569de2398154258
the input sp2d will check input anggaran and do some validation if (sp2d > anggaran) then "sp2d exceed anggaran limit"
Here the initial javascript function to check that function is triggered via onchange
function tesbos(){
var sp2d = $(".sp2d").attr("id");
console.log(sp2d);
}
when i go to row no 2 in sp2d input, still when i check my console log, it still print the sp2d input id of row #1, how to get my input id automatically/dynamically when i go to any row? any help would be appreciated

Assuming you can change the markup, you need to pass the element refernce to the click handler
<input type="text" id="kegbulan-4-sp2d" class="form-control sp2d" name="KegBulan[4][sp2d]" value="680000" onchange="tesbos(this)">
then
function tesbos(el) {
alert(el.id)
}
But I would recommend using jQuery event handlers instead of inlined one, so remove onchange="" from the markup
<input type="text" id="kegbulan-4-sp2d" class="form-control sp2d" name="KegBulan[4][sp2d]" value="680000">
then
jQuery(function($){
$(".sp2d").change(function(){
alert(this.id)
})
})

If I understand correctly, each row of your table includes :
an anggaran (budget) field [fixed value]
a sp2d (spend to date) field [user entered].
And you want to perform a check, on change of every sp2d (spend to date) value against its corresponding anggaran (budget) value.
For this, you do not need to know either of the the fields' IDs. Simply find the anggaran field relative to whichever sp2d field triggers the change event.
First, delete onchange="tesbos()" from the HTML.
Then paste this code between <script></script> tags in your document's HEAD (or in a .js file if your code is organised that way).
jQuery(function($) {
$("#containerID").on('change', ".sp2d", tesbos); // where containerID is the ID of eg. a DIV in which the YII table sits
function tesbos() {
var sp2d_value = $(this).val();
var anggaran_value = $(this).closest("tr").find(".anggaran").val();//find the anggaran field in the same row, and grab its value.
console.log(anggaran_value, sp2d_value);
if(sp2d_value > anggaran_value) {
//anggaran is exceeded
...
} else {
//anggaran is not exceeded
...
}
}
});

Input field show/hide and submit issue with Javascript and html code

Well I've html form where 2 radio button exist. 1) Fixed 2) Tiered.
Fixed radio button has 2 field: 1) Fees 2) Additional Fees
Tiered radio button has 3 field : 1) Tier 1% 2) Tier 1$ 3) Tier 2%
So, If fixed radio button is selected then "Fees" and "Additional Fees" field should be show.
And if Tiered radio button is selected then only "Tier 1%" and "Tier 1$" and "Tier 2%" and "Additional Fees" field should be show.
Now First issue is : after first load the page it's showing Fees and Addition Fees field. It's ok. But if i select Tiered radio button it's show all field including "Fees". but I don't want to show this only "Fees" field.
Second Issue is : If i select Tirered it's process the page but if select Fixed then it's don't submit the page.

Okay, this puzzled me for a bit and I tore apart your form bit by bit until I realized you have your fixed fees wrapped in a div that is nested around table rows. That ain't gonna work.
Make sure one of your radios is checked on load and you set your displays accordingly.
Make sure you can correctly hide-show elements (you can't partially hide row elements by wrapping them in a div. That is not allowed. You can wrap a table in a div, but not a row or cell. You can, however, simply hide/show the tr instead (which I do in the fiddle).
I would recommend adding just one listener (binding) and putting all the logic in there instead of two different binds.
I made a fiddle here: http://jsfiddle.net/C9jad/6/
$(function () {
$('tr#feesFixed')[0].style.display = 'none';
$('div#feesTiered')[0].style.display = 'none';
toggleFees(); // Call this once on ready
console.log($('#offer_typef').prop('checked'))
console.log($('#offer_typet').prop('checked'))
// Single binding here to call encapsulated logic
$('#regForm input:radio').on('click', function(event){
toggleFees();
});
});
function toggleFees() {
if( $('#offer_typef').prop('checked') ) {
$('#feesTiered').hide();
$('#feesFixed').show();
} else {
$('#feesFixed').hide();
$('#feesTiered').show();
}
};
I tore up a few pieces until I realized your real problem was the illegal nesting.
But that should help you fix it straight away.

#1 I will assume that you're working under Bootstrap CSS framework because your <input> class is form-control
#2 I did remove all <table> tags because I couldn't understand anything from your HTML structure
First issue is : after first load the page it's showing Fees and
Addition Fees field. It's ok. But if i select Tiered radio button it's
show all field including "Fees". but I don't want to show this only
"Fees" field.
the solution for this is to wrap:
fixed input into a its own div
tierd inputs (3) into a another div
Leaving Additional fees input without a div since it must be present in both cases
I swapped and assigned show-me to Fixed and show-me2 to tierd (to keep things organized)
HTML:
<form action="" method="post" name="regForm" id="regForm" >
Type: <input type="radio" value="F" id="offer_typef" name="offer_type" required checked /> <b>Fixed</b>
<input type="radio" value="T" id="offer_typet" name="offer_type" required /> <b>Tiered</b>
<!-- Fixed -->
<div id='show-me'>
% <input name="feestructure" placeholder=" Fees " class="form-control" onKeyPress="validate(event)" value="" type="text" id="feestructure" size="40" required />
</div>
<!-- Tierd -->
<div id='show-me2' style='display:none'>
<div class="form-group">
% <input name="trate1" onkeypress="validate(event)" placeholder=" Tier 1 %" type="text" id="trate1" value="<?=$trate1?>" size="40" class="form-control" required />
$ <input name="trate1dollar" onkeypress="validate(event)" placeholder=" Tier 1 $" type="text" id="trate2" value="<?=$trate2?>" size="40" class="form-control" required />
% <input name="trate2" onkeypress="validate(event)" placeholder=" Tier 2 %" type="text" id="trate2" value="<?=$trate2?>" size="40" class="form-control" required />
</div>
</div>
<!-- Additional field -->
$ <span class="required inputfield2"></span><br>
<input name="budget" placeholder=" Additional fees " onkeypress="validate(event)" type="text" value="<?=$budget?>" id="fees" size="40" class="form-control" required />
<!-- Submit button -->
<input name="doRegister" type="submit" id="doRegister" value="Submit Quote" class="btn btn-primary" />
</form>
Second Issue is : If i select Tirered it's process the page but if
select Fixed then it's don't submit the page.
this caused because all of your form inputs has the attribute required, when you click tiered radio button the show-me display is set to none which makes impossible for the form to be submitted unless you remove the required attribute with JS help or validate the form on server-side
I did simple required changes on JS side
#offer_typef attribute changes effect the div #show-me
#offer_typet attribute changes effect the div #show-me2
JS:
$('#regForm').change(function() {
if ($('#offer_typef').prop('checked')) {
$('#show-me').show();
$('#show-me input').attr('required');
} else {
$('#show-me input').removeAttr('required');
$('#show-me').hide();
}
});
$('#regForm').change(function() {
if ($('#offer_typet').prop('checked')) {
$('#show-me2').show();
} else {
$('#show-me2').hide();
}
});
Here's the jsFiddle
Remember: Making an input hidden (display:none;) doesn't mean that it won't be passed to server!
