How to select only one row in table with checkbox - javascript

I have a table with x numbers of rows and 4 columns, one column is checkbox and other three are readonly selectboxs. I want the user to select just 1 row to be editable by checking checkbox in first column then if he check another checkbox in another row, the checkbox he previously checked get unchecked and row get readonly again.
So I want the user to select 1 row only to edit and others be readonly.
here is my code but it is not working.
$(document).ready(function(){
$('.col1, .col2, .col3').attr('disabled', true)
selectRow();
$('.tbl').on('change', '.selectRow', selectRow);
function selectRow() {
$('.tbl tbody tr').each(function () {
$(this).find('.selectRow').each(function () {
var checkedRow = $(this).closest('tr').find('input:checkbox:checked'),
col1 = $(this).closest('tr').find('.col1'),
col2 = $(this).closest('tr').find('.col2'),
col3 = $(this).closest('tr').find('col3');
if (checkedRow){
$('.col1, .col2, .col3').removeAttr('disabled')
checkedRow.siblings().prop('checked', false);
}else{
$('.col1, .col2, .col3').attr('disabled', true)
checkedRow.siblings().prop('checked', false);
}
});
});
}
});

this is my code:

Without jQuery and using event delegation things may be somewhat simpler:
document.addEventListener(`click`, handle);
// disable all selectors initially
document.querySelectorAll(`td select`)
.forEach(s => s.setAttribute(`disabled`, true));
function handle(evt) {
// only do something if a checkbox was clicked
if (evt.target.type === `checkbox`) {
const isChecked = evt.target.checked;
const selectedRow = evt.target.closest(`tr`);
// reset checkboxes, row coloring and disabled state
document.querySelectorAll(`input[type='checkbox']`)
.forEach(cb => {
cb.checked = cb !== evt.target ? false : isChecked;
const row = cb.closest(`tr`);
row.classList[isChecked && row === selectedRow ?
`add` : `remove`](`selected`);
[...row.querySelectorAll(`select`)].filter(r => r !== selectedRow)
.forEach(s => s.setAttribute(`disabled`, true));
selectedRow.querySelectorAll(`select`)
.forEach(s => s[isChecked ?
`removeAttribute` : `setAttribute`](`disabled`, true));
});
}
}
body {
margin: 2rem;

tr.selected {
background-color: lightgreen;

Here's an even more simplified version, acting on the table rows
document.addEventListener(`click`, handle);
// create the table dynamically to keep demo lean
createTable();
function handle(evt) {
if (evt.target.type === `checkbox`) {
const selectedRow = evt.target.closest(`tr`);
document.querySelectorAll(`tr`)
.forEach( row => {
// not selected
if (row !== selectedRow) {
row.querySelector(`[type=checkbox]`).checked = false;
row.classList.remove(`selected`);
return row.querySelectorAll(`select`)
.forEach(s => s.setAttribute(`disabled`, true));
}
// selected
row.classList[[`remove`, `add`][+evt.target.checked]](`selected`);
row.querySelectorAll(`select`).forEach(s =>
s[`${[`set`,`remove`][+evt.target.checked]}Attribute`](`disabled`, true));
});
}
}
function createTable() {
const table = document.createElement(`table`);
const repeat = (str, n) => Array(n + 1).join(str);
const select = `<td><select>
<option>A</option>
<option>B</option>
<option>C</option>
<option>E</option></select></td>`;
const row = `<tr>
<td><input type="checkbox" /></td>
${repeat(select, 3)}</tr>`;
table.insertAdjacentHTML(`beforeend`, repeat(row, 3));
document.body.appendChild(table);
// disable all selectors initially
document.querySelectorAll(`td select`)
.forEach(s => s.setAttribute(`disabled`, true));
}
body {
margin: 2rem;
}
tr.selected {
background-color: lightgreen;
}
tr td:nth-child(1) {
padding-right: 6px;
}

The issue is because checkedRow holds a jQuery object. When you use that in an if condition it will always equate to true. You instead need to get the checked property from that element and use that in the condition instead.
Also note that the logic can be made much more succinct and extensible through the use of common selectors instead of incremental ones. In addition, you should look to add the disabled attribute to the HTML directly. Adding it via JS means that there will be a visible flash where the element is loaded as enabled, then when the DOM loads it will be disabled which is not good for your UX.
jQuery($ => {
selectRow();
$('.tbl').on('change', '.selectRow', selectRow);
function selectRow() {
$('.tbl tbody tr').each(function() {
let $row = $(this);
let $checkbox = $row.find('.selectRow');
$row.find('select').prop('disabled', !$checkbox.prop('checked'));
});
}
});

This works great! uncheck all checkboxes except the one having current focus '.tbl [type="checkbox"]:not(:focus)' then manipulate the select boxes
$(document).ready(function(){
$('.tbl [type="checkbox"]').on('click', function() {
$('.tbl [type="checkbox"]:not(:focus)').prop('checked', false);
$('.tbl select').attr('disabled', true);
$(this).parent().parent().find('select').attr('disabled', !$(this).prop('checked'));
});
});

Save the input the user make even after reload/refresh

I wanted to to add a function that every time the user refresh, reload or even close the page, the user to able to see the data whatever the user had entered previously or choose in the <select>.
Also when the user make an update and refresh they show be able to see the change.
let doc, htm, bod, nav, M, I, S, Q, hC, aC, rC, tC; // for use on other loads
addEventListener('load', () => {
doc = document;
htm = doc.documentElement;
bod = doc.body;
nav = navigator;
M = tag => doc.createElement(tag);
I = id => doc.getElementById(id);
mobile = /Mobi/i.test(nav.userAgent);
S = (selector, within) => {
let w = within || doc;
return w.querySelector(selector);
}
Q = (selector, within) => {
let w = within || doc;
return w.querySelectorAll(selector);
}
hC = (node, className) => {

}
aC = (node, ...classNames) => {
node.classList.add(...classNames);
return aC;

rC = (node, ...classNames) => {
node.classList.remove(...classNames);
return rC;
}
tC = (node, className) => {
node.classList.toggle(className);
return tC;

The localStorage and sessionStorage properties allow to save key/value pairs in a web browser.
The localStorage object stores data with no expiration date. The data will not be deleted when the browser is closed, and will be available the next day, week, or year.
The localStorage property is read-only.
Example:
localStorage.setItem("lastname", "Smith");
// Retrieve
document.getElementById("result").innerHTML = localStorage.getItem("lastname");
If you want to store for example your data ya to local storage, you have to stringify the data, because localstorage accepts only string:
localStorage.setItem("savetab", JSON.stringify(ya));
to retrieve data, you do invers:
ya = JSON.parse(localStorage.getItem("savetab"));
after you rebuild your display yes or no for each row/column
ya is an array of 12 columns and 6 rows so 72 selects
so when you loop over ya, you'll do something like that to reload all selects with data saved:
for(var row = 0; row < 6; row++){
for(var col = 0; col < 12; col++){
$("select").eq(row * 12 + col).val(ya[row, col] == 1 ? "Yes" : "No");
}
}
following your sample:
you execute the localStorage.setItem inside showAverages()
and before the last line you load the data saved
//restore your data here before calling the function average
showAverages();
});

Calculating total average percentage

trying to calculate the average of from Response Percent of each months from Jan to Dec display the average in the total average. I tried all the possible ways by looking at examples and posts from online but nothing seems to be working.
In new to javascript and learning throught online class and looking posts online but its not helping. can any one help me figure it out
const $select_rows = $('.select_row');
const $percent_row = $('.percent_row');
function update_column(col_index) {
const child_index = col_index + 2; // 1 indexed plus 1 for row heading
const $selects = $select_rows.find('td:nth-child(' + child_index + ') select');
if ($selects.length) {
let yes_count = 0;
$selects.each(function() {
if ($(this).val() == 'Yes') {
yes_count++;
}
});
$percent_row.find('td:nth-child(' + child_index + ') .cnt-percent-y').text((yes_count * 100 / $selects.length).toFixed(2));
}
}
function setup() {
$select_rows.each(function() {
$(this).find('select').each(function(index) {
const col_index = index;
$(this).change(function() {
update_column(col_index);
});
update_column(col_index);
});
});
}
setup();
function average(perResponse) {
var total = 0;
var perResponse;
for (var i = 0; i < perResponse.length; i++) {
total += perResponse[i];
}
var avg = total / source.length;
alert(avg)
document.getElementById("result").innerHTML = avg;

Looking to your "average()" function:
"source.length" in your is not initialized - or maybe you intended to use "perResponse.length" instead?
Aside from that "var perRseponse;" seems to be an unnecessary declaration of your parameter (plus typo).

Calculate Percentage of YES/NO and find average

I'm trying to to get the percentage of Yes or No on the HTML Table from the response of the user from the questions of each month and then display the average percentage in the average in the average column of each month (For example if the the user selects 'no'for saving and 'yes' for over budget it should display the average
50% for the month of Jan) but all I'm getting is NaN% for each month . I tried creating a script of each month but shows the same result in average.
Then I trying to add all the Response Percent and get its average and display the average in the total average under total response.
HTML, CSS and JS:
$(function() {
mon_jan();
});
function mon_jan() {
var target_span = $('#span1');
count_yes_no(target_span);
}
function count_yes_no(spn) {
var yes = 0;
var no = 0;
var l = 0;
spn.find('select').each(function() {
if ($(this).val() == 'Yes') {
yes++;
}
if ($(this).val() == 'No') {
no++;
}
l++;
});
// update count values summary
$('.cnt-yes').text(yes);
$('.cnt-no').text(no);
$('.len').text(parseInt(l));
$('.cnt-percent-y').text((yes * 100 / l).toFixed(2));
$('.cnt-percent-n').text((no * 100 / l).toFixed(2));
}
$(function() {
mon_feb();
});
function mon_feb() {
var target_span = $('#span1');
count_yes_no(target_span);
}
function count_yes_no(spn) {
var yes = 0;
var no = 0;
var l = 0;
spn.find('select').each(function() {
if ($(this).val() == 'Yes') {
yes++;
}
if ($(this).val() == 'No') {
no++;
}
l++;
});
// update count values summary
$('.cnt-yes').text(yes);
$('.cnt-no').text(no);
$('.len').text(parseInt(l));
$('.cnt-percent-y').text((yes * 100 / l).toFixed(2));
$('.cnt-percent-n').text((no * 100 / l).toFixed(2));

One problem is that span is not a valid child element of a tr. Removing the span and giving the id to the tr would probably work better.
My jQuery is pretty rusty but I took a stab at a partially working solution in case it helps:
const $select_rows = $('.select_row');
const $percent_row = $('.percent_row');
function update_column(col_index) {
const child_index = col_index + 2; // 1 indexed plus 1 for row heading
const $selects = $select_rows.find('td:nth-child(' + child_index + ') select');
if($selects.length) {
let yes_count = 0;
$selects.each(function() {
if($(this).val() == 'Yes') {
yes_count++;
}
});
$percent_row.find('td:nth-child(' + child_index + ') .cnt-percent-y').text((yes_count * 100 / $selects.length).toFixed(2));
}
}
function setup() {
$select_rows.each(function() {
$(this).find('select').each(function(index) {
const col_index = index;
$(this).change(function() {
update_column(col_index);
});
update_column(col_index);
});
});
}
setup();

multiple selects with same value do this

i have diferent select options with the same values in a table.
how do i make that when all selects get the same value ("2") do something (add disabled atributte to an input)?
<table>
<td>
<select class="class1">
<option value="1">SI</option>
<option value="2">NO</option>
</select>
</td>
<td>
<select class="class1">
<option value="1">SI</option>
<option value="2">NO</option>
</select>
</td>
<td>
<select class="class1">
<option value="1">SI</option>
<option value="2">NO</option>
</select>
</td>
</table>
<input type="checkbox" class="checkbox" id="x">
Read the values into an array values. If all of the values are 2 the disable the checkbox using .prop('disabled', true):
$('.class1').on('change', function() {
let values = $('.class1').map(function() {
return +this.value;
}).get();
values.some(checkValue) || $('#x').prop('disabled', true);
});
function checkValue( value ) {
return value !== 2;
}

<input type="checkbox" class="checkbox" id="x">
You can do it as follows: Push the value of each select in an array and use unique() to only keep unique values. In case you want to disable the input if the values of the selects are the same (either 1 or 2), disable the input if the length of this array is 1.
$("select").on("change", function() {
let a = [];
$("select").each(function() {
a.push($(this).val());
$.unique(a);
});
if (a.length === 1) {
$(".checkbox").attr("disabled", true);
}
else {
$(".checkbox").removeAttr("disabled");
}
});

How do I unhide a row after it is hidden?

The following code hides the first row of the table but it doesn't make the first row visible again when the checkbox is clicked again. Can someone help?
I even tried looping through the tables and toggling the row visibility but that is very slow due to the amount of tables in the html.
Alternate suggestions are welcome. This would be too painful to do in C#.
$(document).ready(function() {
$('#chkNA,#chkSC,#chkNS,#chkIss,#chkIP').click(function() {
var row;
if (this.id == 'chkNS') {
row = $('.TF-StatusNotStarted').closest('tr');
}
if (this.id == 'chkSC') {
row = $('.TF-StatusCompleted').closest('tr');
}
if (this.id == 'chkNA') {
row = $('.TF-StatusNA').closest('tr');
}
if (this.id == 'chkIss') {
row = $('.TF-StatusIssue').closest('tr');
}
if (this.id == 'chkIP') {
row = $('.TF-StatusInProgress').closest('tr');
}
var tabletest = row.parent().parent();
row.toggle();
if (tabletest.find('tbody > tr:gt(0):visible').length > 0) {
if (tabletest.find('tbody > tr:first').is(":visible") == false) {
tabletest.find('tbody > tr:first').show();
}
}
if (tabletest.find('tbody > tr:gt(0):visible').length > 0 && tabletest.find('tbody > tr:first').is(':visible')) {
tabletest.find('tbody > tr:first').hide();
}
});
});

Update 2
Updated the scenario to target the header row instead of the rows.
Update 1
I have updated the code snippet with relevant details to help you come to a proper solution for you scenario.
Added select with same options
Select the Option with same value as the input being checked,
If the checkbox is checked it will show the valid rows, otherwise it hides them
Intial Answer
From your code it is apparent you are using jQuery to show/hide the rows. jQuery has 3 functions that perform this behavior. The obvious ones show() and hide(), and the less obvious toggle(). If your intent is to 'toggle' the visibility of an element, you should be using toggle() otherwise you have to track the state of the element yourself.
Here are some reference material for these methods to help you out.
show()
hide()
toggle()
Here is a simple example to help you out.
$(function() {
function showSelected() {
var selected = [];
$('input:checked')
.map(function(idx, elm) {
selected.push($(elm).val());
});
$('#report').text(JSON.stringify(selected));
}
$('input').click(function(event) {
// update the selected report
showSelected();
// get the value of this element
var value = $(this).val();
// options that have this value and are checked
var selector = `option[value="${value}"]:checked`;
if ($(this).is(':checked')) {
$(selector).closest('table').find('thead tr').show()
} else {
$(selector).closest('table').find('thead tr').hide()
}
});
showSelected();
$('input').click();
});
