Enable textbox withing a loop when checked - javascript

How can i enabled my textbox within a loop when it check the checkbox?. Can you help me guys how to do it.
<table class="table table-bordered table-hover mt-2">
<thead>
<tr>
<th>Select</th>
<th>Duties and Responsibilities</th>
<th>Weight of Duties</th>
<th>Rate of Department Head</th>
<th>Remarks</th>
</tr>
</thead>
<tbody>
#for (int x = 0; x <= 7; x++)
{
<tr>
<td><input type="checkbox" class="form-control" /></td>
<td><input type="text" name="JdDescription" class="form-control" disabled/></td>
<td><input type="text" readonly name="WeightofDuties" class="form-control" /></td>
<td><input type="text" name="RateofHead" class="form-control" disabled/></td>
<td><input type="text" name="Remarks" class="form-control" disabled/></td>
</tr>
}
</tbody>

Fetch the parent <tr> element upon clicking a checkbox, then enable text inputs within this <tr> node:
$('input[type=checkbox]').change(function () {
var disabled = this.checked ? '' : 'disabled';
$(this).parents('tr').find('input[type=text]').prop('disabled', disabled);
});
This will also disable the input[type=text] fields again upon unchecking the checkbox. If you only want to enable a specific text field, modify the argument of .find('input[type=text]') selector accordingly.
If you also want to toggle the readonly text field, do it like so:
$(this).parents('tr').find('input[name="WeightofDuties"]')
.attr('readonly', !this.checked);

How to calculate sum of one field in table and put it in an input

I have a table in razor and I sent the data by ViewBag from controller
<table>
<thead>
<tr>
<th>Name</th>
<th>Category</th>
<th>Price</th>
<th>Count</th>
</tr>
</thead>
<tbody>
#foreach(var item in ViewBag.Products)
{
<tr>
<td>#item.Name</td>
<td>#item.Category</td>
<td>
<input type="text" class="form-control" value="#item.Price" />
</td>
<td>
<input type="text" class="form-controll" value="#item.Count" />
</td>
</tr>
}
</tbody>
</table>
<input type="text" class="form-control" value="#Model.TotalPrice" />
I want to multiple count and price of each row and put it in another input using javascript. and when the user change the value of input, that input that holds the value could change automatically.
if anyone can help me i would be appreciated.
If you are using jquery then it can be achieve as below.
You can update your total on every key press in price or count input.
Add some class to your input. In my example I've took class as price, and class total for display sum.
Add keyup event as below. Also trigger it on $(document).ready to initially set the total value.
$('.price').on('keyup', function() {
var val = +$(this).val();
var valSibling = +$(this).parent().siblings('td').find('.price').val();
if (isNaN(val) || isNaN(valSibling))
return;
$(this).parent().siblings('td').find('.total').val(val * valSibling);
var finaltotal = 0;
$('.total').each(function() {
if(!isNaN($(this).val()))
finaltotal += Number($(this).val());
});
$('.finaltotal').val(finaltotal);
});
$(document).ready(function(){
$('.price').trigger('keyup');
});

I want to multiple count and price of each row and put it in another input using javascript.
You can add another td in each tr. Then loop through all the tbody tr to calculate the value:
var tr = document.querySelectorAll('tbody tr');
function calculate(){
tr.forEach(function(el){
var td = el.querySelectorAll('td');
// If there is invalid number in input then no change in total.
if (isNaN(td[2].querySelector('input').value) || isNaN(td[3].querySelector('input').value))
return;
td[4].querySelector('input').value = td[2].querySelector('input').value * td[3].querySelector('input').value;
});
}
calculate();
.form-control{
width: 50px;
}
<table>
<thead>
<tr>
<th>Name</th>

<th>Price</th>

<th>Total</th>

How to get reference to another object on other column on same row in a table in Javascript?

I want to set disabled=false for the input box on 3rd column when a user 'check' the checkbox on the 2nd column on Same row
And again disable if user 'uncheck' the checkbox.
<!DOCTYPE html>
<html>
<body>
<p>Check the checkbox to display which type of form element it is.</p>
<table border='1' cellpadding='5'>
<tr>
<td>Item1</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type='number' disabled></td>
<tr>
<tr>
<td>Item2</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type='number' disabled></td>
<tr>
<tr>
<td>Item3</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type='number' disabled></td>
<tr>
</table>
<script>
// function myFunction(item) {
// var x = document.getElementById(item).....how to get a reference to parent;
// x.disabled=false;
// }
</script>
</body>
</html>
I tried with this reference but that have not gave me any solution.
So how can i get the reference to the input box from the checkbox?
I browsed internet but have not get any solution .
You could give the inputs an id attribute for later addressing this element.
function myFunction(item) {
var x = document.getElementById(item);
x.disabled = !x.disabled;
}
<p>Check the checkbox to display which type of form element it is.</p>
<table border="1" cellpadding="5">
<tr>
<td>Item1</td>
<td><input type="checkbox" onclick="myFunction('itemInput1')"></td>
<td><input type="number" id="itemInput1" disabled></td>
</tr>
<tr>
<td>Item2</td>
<td><input type="checkbox" onclick="myFunction('itemInput2')"></td>
<td><input type="number" id="itemInput2" disabled></td>
</tr>
<tr>
<td>Item3</td>
<td><input type="checkbox" onclick="myFunction('itemInput3')"></td>
<td><input type="number" id="itemInput3" disabled></td>
<tr>
</table>
With Element.closest, as #August mentioned and Document.querySelector
function myFunction(element) {
var x = element.closest('tr').querySelector('input[type="number"]');
x.disabled = !x.disabled;
}
<p>Check the checkbox to display which type of form element it is.</p>
<table border="1" cellpadding="5">
<tr>
<td>Item1</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type="number" disabled></td>
</tr>
<tr>
<td>Item2</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type="number" disabled></td>
</tr>
<tr>
<td>Item3</td>
<td><input type="checkbox" onclick="myFunction(this)"></td>
<td><input type="number" disabled></td>
<tr>
</table>
Don't go back to DOM with document.getElementById to get your element, there is no point of doing that.
Try to use the event reference, when calling myFunction the event (onclick) is passed which has property "target".
To understand better do console.log(item); inside the function.
From there, inside your function you could do item.target.closest('tr') to identify the parent of the cell.
<script>
function myFunction(item) {
console.log(item);
var x = item.target.closest('tr');
x.disabled=false;
}
</script>

Apply function in dynamically added each row differently with jQuery

I have added new rows dynamically with jQuery and applied a function but I want to apply this differently for each row. right now its applying commonly for every rows.
HTML code:
<button type="button" id="addBankRow" >add</button>
<table class="table table-bordered" id="dynamic_field_bank">
<thead>
<tr>
<th width="10%">Deposit Date</th>
<th width="10%">Deposit Method</th>
<th width="25%">Bank Title</th>
<th width="25%">Account No</th>
<th width="20%">Deposit Amount</th>
<th width="10%">#</th>
</tr>
</thead>
<tbody>
<tr class="bank_deposit">
<td><p>12/10/17</p></td>
<td>
<select class="form-control" id="deposit_method">
<option>Bank</option>
<option>Vault</option>
</select>
</td>
<td><input id="bank_title" name="bank_title" required="required" type="text"></td>

</select>
</td>
<td><input id="deposit_amount" name="deposit_amount" required="required" type="number" min="0"></td>
<td>
</td>
</tr>
</tbody>

Jquery Codes:
var i=1;
$('#addBankRow').click(function(){
i++;
$('#dynamic_field_bank').append('<tr id="row'+i+'" class="dynamic-added" ><td><p>12/10/17</p></td><td><select class="form-control" id="deposit_method"><option>Bank</option><option>Vault</option></select></td><td><input id="bank_title" name="bank_title" required="required" type="text"></td><td><select class="form-control" id="bank_ac_no"><option>151035654646001</option><option>151035654646002</option><option>151035654646003</option></select></td><td><input id="deposit_amount" name="deposit_amount" required="required" type="number" min="0"></td><td>X</td></tr>');
});
$(document).on('click', '.btn_remove', function(e){
e.preventDefault();
var button_id = $(this).attr("id");
$('#row'+button_id+'').remove();
});
$("tbody").on('change', "#deposit_method", function() {
if ($(this).val() == 'Vault'){
$('#bank_title, #bank_ac_no').hide();
}
else if ($(this).val() == 'Bank'){
$("tr.bank_deposit").each(function (){
$('#bank_title, #bank_ac_no').show();
});
}
});
When I am changing the deposit method I want to hide/show the two fields in each row but its applying in every row.
see the demo with codes:
https://jsfiddle.net/wasid/33qp9ewn/3/
You can add an attribute (like row-id) for inputs to determine which row has been processed. I modified HTML and Javascript codes. Also, you can take a look modifed codes as Fiddle Demo

Detect html table cell value change

How am I able to detect change in html table on any cell? Currently I can only detect change in one cell, I could repeat the same code for all table cell ID but wondering if there is an efficient way.
Note that I have other inputs in my form and only wish to detect ones relevant to the table below:
Code:
html:
<table id="myTable" border="1" data-mini="true" >
<tbody>
<tr>
<th>Drawing Number</th>
<th>Description</th>
<th>Sheet Number</th>
<th>Issue</th>
</tr>
<tr>
<td><input name="drawing-n-1" id="drawing-n-1" type="text" /></td>
<td><input name="drawing-d-1" type="text" /></td>
<td><input name="drawing-s-1" type="text" /></td>
<td><input name="drawing-i-1" type="text" /></td>
<td><input name="drawing-n-2" id="drawing-n-2" type="text" /></td>
<td><input name="drawing-d-2" type="text" /></td>
<td><input name="drawing-s-2" type="text" /></td>
<td><input name="drawing-i-2" type="text" /></td>
</tr>
</tbody>
</table>
javascript:
var drawing_input = 'drawing-n-1';
$('#'+drawing_input).change(function(e) {
alert("aha");
var data = $('#'+drawing_input).val();
});
With jQuery you needn't be so specific. Just change the selector to listen for all <input>s.
$('input').on('change',
This selector will pick every <input> on the page.
Or if you need to isolate the table's inputs, add the table's id in the selector.
$('#xTable input').on('change'...
This selector will pick every <input> within the table.
Saw that you needed only to listen for inputs with ids. If so then you can use the brackets and ^=:
$("#xTable input[id^='drawing-n-']").on('change'....
This means get any <input> that has an [ id that starts ^= with "drawing-n-" ] which is in a <table> with the id of xTable.
That selector will pick only input#drawing-n-1 and input#drawing-n-2
Demo
$("#xTable input[id^='drawing-n-']").on('change', function(e) {
var data = $(this).val();
console.log(data);
});
<table id="xTable" border="1" data-mini="true">
<tbody>
<tr>
<th>Drawing Number</th>
<th>Description</th>
<th>Sheet Number</th>
<th>Issue</th>
</tr>
<tr>
<td><input name="drawing-n-1" id="drawing-n-1" type="text" /></td>

<td><input name="drawing-i-1" type="text" /></td>

Column search on top of table with responsive table

I have prepared table with server side script for column search, everything works fine, but stuck with one issue for responsive table,
Below is my table,
<table class="table table-striped table-bordered table-hover dt-responsive nowrap" width="100%" id="3table">
<thead>
<tr>
<th> ID</th>
<th>Number</th>
<th>Number1</th>
<th> Number2</th>
<th>Plant</th>
<th>Part</th>
<th>Description</th>
<th>Quantity</th>
<th>Date</th>
<th>To</th>
<th>Date3</th>
<th>Transport</th>
<th>Docket</th>
</tr>
</thead>
<thead>
<tr>
<td><input type="text" data-column="1" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="2" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="3" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="4" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="5" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="6" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="7" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="8" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="9" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="10" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="11" class="form-control" placeholder="Search"></td>
<td><input type="text" data-column="12" class="form-control" placeholder="Search"></td>
</tr>
</thead>
<tbody>
</tbody>
</table>
I had kept another with for search box, then sending search value with below jquery code
// Apply the search
$('.form-control').on( 'keyup click', function () { // for text boxes
var i =$(this).attr('data-column'); // getting column index
var v =$(this).val(); // getting search input value
var table = $('#3table').DataTable();
table.columns(i).search(v).draw();
});
Now when i change resolution, search boxes are not changed resolution as other columns and rows, All search boxes are not wrapping, but showing in 1 row only. if i remove 2nd , then my datatable is completely responsive,means i can see + sign for first column for columns which are getting hidden.
How can i make search boxes responsive as well?
CAUSE
You have two thead elements, there should be only one.
SOLUTION
Combine two header rows under one thead element.
<table class="table table-striped table-bordered table-hover dt-responsive nowrap" width="100%" id="3table">
<thead>
<tr>
<th> ID</th>
<th>Number</th>
<th>Number1</th>
<th> Number2</th>
<th>Plant</th>
<th>Part</th>
<th>Description</th>
<th>Quantity</th>
<th>Date</th>
<th>To</th>
<th>Date3</th>
<th>Transport</th>
<th>Docket</th>
</tr>
<tr>
<th><input type="text" data-column="1" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="2" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="3" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="4" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="5" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="6" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="7" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="8" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="9" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="10" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="11" class="form-control" placeholder="Search"></th>
<th><input type="text" data-column="12" class="form-control" placeholder="Search"></th>
</tr>
</thead>
<tbody></tbody>
</table>
NOTES
There are other issues with your code:
ID should not start from a number, consider giving your table another ID
Your code for search boxes should be changed to:
// Prevent sorting when search boxes are clicked
$('#3table thead').on( 'click', '.form-control', function (e) { // for text boxes
e.stopPropagation();
});
// Perform column search
$('#3table thead').on( 'keyup change', '.form-control', function (e) {
var i = $(this).attr('data-column'); // getting column index
var v = $(this).val(); // getting search input value
var table = $('#3table').DataTable();
table.columns(i).search(v).draw();
});
Use orderCellsTop: true option to use top header row for sorting.
