Update total in table row with jquery - javascript

I have a table
<table>
<tbody>
<tr>
<td><input type="text" name="quantity" /></td>
<td><input type="text" name="price" /></td>
<td><input type="text" name="total" disabled />
</tr>
<tr>
<td><input type="text" name="quantity" /></td>
<td><input type="text" name="price" /></td>
<td><input type="text" name="total" disabled />
</tr>
<tr>
<td><input type="text" name="quantity" /></td>
<td><input type="text" name="price" /></td>
<td><input type="text" name="total" disabled />
</tr>
<tr>
<td><input type="text" name="quantity" /></td>
<td><input type="text" name="price" /></td>
<td><input type="text" name="total" disabled />
</tr>
</tbody>
</table>
How can I update the total input field when a change in quantity or price happens?
I have thought of something like
$('table tbody tr td').filter(':nth-child(1), :nth-child(2)').children('input').change(function() {
$(this).parent('td').siblings('td').filter(':nth-child(3)').val(?);
});
but it seems a bit unhandy.


You can use:
$('table tbody tr td').find('input').keyup(function() {
var total=0;
total=(parseInt($(this).parent('td').siblings('td').not(':nth-child(3)').find('input').val())||0)+(parseInt($(this).val())||0);
$(this).closest('tr').find('input:last').val(total)
});
Working Demo


Much easy to read and control if you can assign some dummy class to quantity, price and total input.
Something like this:
HTML
<table>
<tbody>
<tr>
<td><input type="text" class="qty" name="quantity" /></td>
<td><input type="text" class="prc" name="price" /></td>
<td><input type="text" class="total" name="total" disabled />
</tr>
<tr>
<td><input type="text" class="qty" name="quantity" /></td>
<td><input type="text" class="prc" name="price" /></td>
<td><input type="text" class="total" name="total" disabled />
</tr>
<tr>
<td><input type="text" class="qty" name="quantity" /></td>
<td><input type="text" class="prc" name="price" /></td>
<td><input type="text" class="total" name="total" disabled />
</tr>
<tr>
<td><input type="text" class="qty" name="quantity" /></td>
<td><input type="text" class="prc" name="price" /></td>
<td><input type="text" class="total" name="total" disabled />
</tr>
</tbody>
</table>
Script
$('table tbody tr').find('.qty, .prc').on('keyup',function() {
var parent = $(this).parents('tr');
var quantity = parseInt(parent.find('.qty').val())||0;
var price = parseInt(parent.find('.prc').val())||0;
parent.find('.total').val(quantity*price);
});
Check working example here


Personally, i prefer not to select elements by their position. If you wind up changing them later, or adding another your code is broken.
I would do something like:
$(this).closest('tr').find('input[name=total]').val(?);

When i change the value in table tblProducts it calculate grand total of two table, how to separate the grand total for each table.
Sorry to ask, i really have no idea

You need to only select the .subtot input inside the current table you're in before updating it. Try this.
$(function () {
$('.pnm, .price, .subtot, .grdtot').prop('readonly', true);
$('table').each(function(){
var $tbl = $(this);
var $tblrows = $tbl.find('tbody tr');
$tblrows.each(function (index) {
var $tblrow = $(this);
$tblrow.find('.qty').on('change', function () {
var qty = $tblrow.find("[name=qty]").val();
var price = $tblrow.find("[name=price]").val();
var subTotal = parseInt(qty, 10) * parseFloat(price);
if (!isNaN(subTotal)) {
$tblrow.find('.subtot').val(subTotal.toFixed(2));
var grandTotal = 0;
$tbl.find(".subtot").each(function () {
var stval = parseFloat($(this).val());
grandTotal += isNaN(stval) ? 0 : stval;
});
$tbl.find('.grdtot').val(grandTotal.toFixed(2));
}
});
});
});
});

In your jquery selectors just add your table id, and if you have multiple tables you can wrap the code in a function
function addTotal(tableID) {
$('.pnm, .price, .subtot, .grdtot').prop('readonly', true);
var $tblrows = $(tableID + " tbody tr");
$tblrows.each(function(index) {
var $tblrow = $(this);
$tblrow.find( '.qty').on('change', function() {
var qty = $tblrow.find("[name=qty]").val();
var price = $tblrow.find("[name=price]").val();
var subTotal = parseInt(qty, 10) * parseFloat(price);
if (!isNaN(subTotal)) {
$tblrow.find('.subtot').val(subTotal.toFixed(2));
var grandTotal = 0;
$(tableID + " .subtot").each(function() {
var stval = parseFloat($(this).val());
grandTotal += isNaN(stval) ? 0 : stval;
});
$(tableID + ' .grdtot').val(grandTotal.toFixed(2));
}
});
});
}
addTotal("#tblProducts");

You really don't need to loop over the rows to add the event listener.
You can use closest() within the handler function to isolate the row and table the element is in then use find()
$('.pnm, .price, .subtot, .grdtot').prop('readonly', true);
$('.qty').on('change', function() {
var $row = $(this).closest('tr'),
qty = $(this).val(),
price = $row.find(".price").val(),
subTotal = parseInt(qty, 10) * parseFloat(price);
if (!isNaN(subTotal)) {
$row.find('.subtot').val(subTotal.toFixed(2));
var grandTotal = 0;
var $table = $row.closest('table')
$table.find(".subtot").each(function() {
var stval = parseFloat($(this).val());
grandTotal += isNaN(stval) ? 0 : stval;
});
$table.find('.grdtot').val(grandTotal.toFixed(2));
}
});

Changing the value of multiple inputs [duplicate]

This question already has answers here:
jQuery change input text value
(6 answers)
Closed 3 years ago.
Sorry for the simple question. I have a form with multiple input fields.
<table>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
</table>
I want to change the value of all class=amount inputs to 10. I've tried the following simple script but it doesn't seem to be working?
$(".amount").each(function(){
this.value = '10';
})

If you really just want to change the value of all .amount, no need to iterate them.
$(".amount").val(10)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
</table>

Change your jQuery code to the following:
$(".amount").val(100);

$('.amount').val(10);
OR
$('.amount').each(function(index,element) {
element.value = 10;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>
<tr>
<td><input type="number" name="amount[]" class="amount" value="0"></td>
<td><input type="text" name="name[]" class="name"></td>
</tr>

EDGE laggy in showing keyboard input

The code below, when executed by edge shows a lot of input lag.
Steps to reproduce:
copy paste the snippit in a local html file.
It will not be reproducable from the snippit editor in stackoverflow.
open it with edge
make sure auto fill form fields are ON in edge settings/advanced . there is no need to actually have these form fields
slam your keyboard with random keys (more than 10 keys/sec)
it's a bit rude but necessary to demonstrate. On a production page where there is css, normal typing is enough to see the issue.
Not sure if it matters, Version where this issue works
Microsoft Edge 42.17134.1.0
Microsoft EdgeHTML 17.17134
You will see the input still being filled in even if you already stopped slamming the keyboard.
Workaround found but not acceptible for our situation
Disable "save form entries" option in edge. (not acceptable as we cannot force all our users to do this)
remove form element (obviously not acceptable)

How to search by filter in a table with rowspan

I need to search all my table and display the corresponding line.
I can not display the result of the search correctly when the search is on the first column, this column contains a rowspan. Instead of displaying the 2 or 3 corresponding lines, it's just the first one displayed
Input search
<div>
<input id="searchInput" type="text" placeholder="Search.."

Validation errors with form

I am doing an assignment for school and it is a restaurant website. I am working on the "order online" page. I must include a table in my website so I put it in my form with all of my menu items and their cost and the total. The problem I am having is: I have each menu item wrapped in a form element in order to make my Javascript work but when I try to validate it, I get errors because my fieldset is outside of a form element and if I move it around I go from 3 errors to 150 and I just don't really understand why. Also, this is causing a problem with my reset button because the reset button is in a different form element then each menu item, and finally I can't get my grand total at the bottom working.

Use a single form element around everything and you can still access the correct inputs, relative to the row.
For example, your function could look like:
function multiply(element) {
var row = element.parentNode.parentNode;
row.querySelectorAll('input[name=TOTAL]')[0].value = element.value * row.querySelectorAll('input[name=PRICE]')[0].value;
}
First it gets the row that contains the three inputs, then from there it finds the TOTAL and PRICE inputs by name using querySelectorAll.
Note: querySelectorAll isn't supported by IE7 or lower but I doubt that will matter for an assignment.
