I guess this snippet is what you need.
This is the simplest way but you could do better if you want.
$(document).ready(function(){
$('input[type=checkbox]').change(function(){
var count = 0;
$.each($('input[type=checkbox]'), function(){
if($(this).prop('checked') == true){
count++;
}
});
if(count == 1) {
$('#btnEditID').prop('disabled', false);
$('#btnDeleteID').prop('disabled', false);
$('#btnAddID').prop('disabled', true);
}
else {
$('#btnDeleteID').prop('disabled', false);
$('#btnEditID').prop('disabled', true);
$('#btnAddID').prop('disabled', true);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div>
<button type="button" id="btnAddID" name="btnAdd"> Add </button>
<button type="button" id="btnEditID" name="btnEdit"> Edit </button>
<button type="button" id="btnDeleteID" name="btnDelete"> Delete </button>
</div>
<br/>
<div>
<table>
<thead>
<tr>
<th></th>
<th>ID</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="checkbox" /></td>
<td>1</td>
<td>ABC</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>2</td>
<td>XYZ</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>3</td>
<td>PQR</td>
</tr>
<tr>
<td><input type="checkbox" /></td>
<td>4</td>
<td>MLN</td>
</tr>
</tbody>
</table>
</div>
</div>


Try this:
$('input[type="checkbox"]').change(function(){
var checked = $('input[type="checkbox"]:checked').length;
if(checked === 0){
$("button").prop('disabled',false);
}else if(checked === 1){
$("button").prop('disabled',false);
$("#btnAddID").prop('disabled', true);
}else{
$("#btnAddID,#btnEditID").prop('disabled', true);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<button type="button" id="btnAddID" name="btnAdd"> Add </button>
<button type="button" id="btnEditID" name="btnEdit"> Edit </button>
<button type="button" id="btnDeleteID" name="btnDelete"> Delete </button>

Get different Column value when current row checkbox is selected

I have been looking around everywhere for a solution and I just can't find any.
What I'm trying to do here is get the third column value i.e price when the checkbox in the first column is selected. I'll eventually use the column value to calculate the total which will be thrown into a div.
<body>
<form action="" method="post"><table id="tableid">
<tr>
<th><b>Menu:</b></th>
</tr>
<tr>
<th></th>
<th>Item</th>
<th>Price</th>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="27"></td>
<td>Item1</td>
<td class="">100</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="28"></td>
<td>Item2</td><td class="">200</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="29"></td>
<td>Item3</td>
<td class="">300</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="30"></td>
<td>Item4</td>
<td class="">400</td>
</tr>
</table>
</form>
<div id="container"></div>
</body>
I've tried several options from $(this).parent().find()....and nth-child() but i don't seem to be getting how "this" works
sample code:
$(document).ready(function(){
$('.chkbx').change(function(){
$('.chkbx:checked').each(function(){
total+=parseInt($(this).parent().find("td").text());
});
//var item=$(".chkbx tr:nth-child(2)").text();
$("#container").html(total);
});
});
Is my approach wrong? How should I go about this? Will using classes be of any help?
Thanks in Advance!!
P.S: Very new to JS and JQuery.

You need to target last td element so you can use .closest() to traverse up-to <TR> then use .eq(index)1 to target the desired element
total+= parseInt($(this).closest('tr').find("td:eq(2)").text(), 10);
$(document).ready(function() {
$('.chkbx').change(function() {
var total = 0;
$('.chkbx:checked').each(function() {
total += parseInt($(this).closest('tr').find("td:eq(2)").text(), 10);
});
console.clear();
console.log(total);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tableid">
<tr>
<th><b>Menu:</b></th>
</tr>
<tr>
<th></th>
<th>Item</th>
<th>Price</th>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="27"></td>
<td>Item1</td>
<td class="">100</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="28"></td>
<td>Item2</td>
<td class="">200</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="29"></td>
<td>Item3</td>
<td class="">300</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="30"></td>
<td>Item4</td>
<td class="">400</td>
</tr>
</table>
1I would recommend, assigning a CSS class to target the element rather than using index.
HTML
<td class="price">400</td>
Script
total+= parseInt($(this).closest('tr').find("td.price").text(), 10);

You can use siblings with last like this.
$(this).parent().siblings(":last").text();

Use need to use closest() to find the tr then use find with :nth-child() to get the specific td
$(document).ready(function(){
$('.chkbx').change(function(){
var total = 0;
$('.chkbx:checked').each(function(){
total+=parseInt($(this).closest('tr').find("td:nth-child(3)").text());
});
//var item=$(".chkbx tr:nth-child(2)").text();
$("#container").text(total);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" method="post"><table id="tableid">
<tr>
<th><b>Menu:</b></th>
</tr>
<tr>
<th></th>
<th>Item</th>
<th>Price</th>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="27"></td>
<td>Item1</td>
<td class="">100</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="28"></td>
<td>Item2</td><td class="">200</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="29"></td>
<td>Item3</td>
<td class="">300</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="30"></td>
<td>Item4</td>
<td class="">400</td>
</tr>
</table>
</form>
<span id='container'> </span>

You were not tracking the TD for price column correctly, and you need to declare the total variable outside the .each() otherwise the scope wont allow to access the variable and populate the total, see below for a demo
var total = 0;
$(document).ready(function() {
$('.chkbx').change(function() {
$('.chkbx:checked').each(function() {
//console.log($(this).parent().next().next().text());
total += parseInt($(this).parent().next().next().text());
});
//var item=$(".chkbx tr:nth-child(2)").text();
$("#container").html(total);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
TOTAL
<div id="container"></div>
<form action="" method="post">
<table id="tableid">
<tr>
<th><b>Menu:</b></th>
</tr>
<tr>
<th></th>
<th>Item</th>
<th>Price</th>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="27"></td>
<td>Item1</td>
<td class="">100</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="28"></td>
<td>Item2</td>
<td class="">200</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="29"></td>
<td>Item3</td>
<td class="">300</td>
</tr>
<tr>
<td><input type="checkbox" class="chkbx" name="item" value="30"></td>

<td class="">400</td>

How can I get the value of the last th?

I need to print the word of Emails on click of all checkboxes. How can I do that? Here is my HTML structure:
$('td input').on('change', function() {
var header_name = $(this).closests('tr').sibilings('th').last().text();
console.log(header_name);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tbody>
<tr>
<th><input type="checkbox" class="all_checkboxes"></th>
<th>Emails</th>
</tr>
<tr>
<td><input type="checkbox" data-id="email"></td>
<td>email</td>
</tr>
<tr>
<td><input type="checkbox" data-id="gmail"></td>
<td>gmail</td>
</tr>
<tr>
<td><input type="checkbox" data-id="aol"></td>
<td>aol</td>
</tr>
<tr>
<td><input type="checkbox" data-id="chmail"></td>
<td>chmail</td>
</tr>
</tbody>
</table>

Firstly you have a couple of typos. closests() should be closest() and sibilings() needs to be siblings().
The issue itself is because your DOM traversal is not correct. You're trying to look at sibling th of the parent tr to the clicked input, when the th you're aiming for is in a completely different row.
To fix this you should use closest() to get the table, then find() the tr:last, like this:
$('td input').on('change', function() {
var header_name = $(this).closest('table').find('th:last').text();
console.log(header_name);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tbody>
<tr>
<th><input type="checkbox" class="all_checkboxes"></th>
<th>Emails</th>
</tr>
<tr>
<td><input type="checkbox" data-id="email"></td>
<td>email</td>
</tr>
<tr>
<td><input type="checkbox" data-id="gmail"></td>
<td>gmail</td>
</tr>
<tr>
<td><input type="checkbox" data-id="aol"></td>
<td>aol</td>
</tr>
<tr>
<td><input type="checkbox" data-id="chmail"></td>
<td>chmail</td>
</tr>
</tbody>
</table>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tbody>
<tr>
<th><input type="checkbox" class="all_checkboxes"></th>

</tr>
<tr>
<td><input type="checkbox" data-id="email"></td>
<td>email</td>
</tr>
<tr>
<td><input type="checkbox" data-id="gmail"></td>
<td>gmail</td>
</tr>
<tr>
<td><input type="checkbox" data-id="aol"></td>
<td>aol</td>
</tr>
<tr>
<td><input type="checkbox" data-id="chmail"></td>
<td>chmail</td>
</tr>
</tbody>
</table>
<script>
$('td input, th input').on('change', function(){
var header_name = $( "tr:first" ).last().text();
console.log(header_name);
})
</script>

Display respective text box when checkbox is checked in a table

Display respective text box when checkbox is checked in the table which is inside the form.
The rows will generate dynamically depending upon the data send from the server, along with the data.
When the checkbox is checked the text box of that row should be displayed otherwise it should be hidden
<div class="container-fluid">
<form class="available-products-table">
<table class="table">
<fieldset>
<legend>Avaliable Products</legend>
<thead>
<tr>
<th>S.no</th>
<th>Product Name</th>
<th>Quanity</th>
<th>Brand</th>
<th>Color</th>
<th>Status</th>
<th>Quanity</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Shoes</td>
<td>50</td>
<td>adidas</td>
<td>Black</td>
<td><input type="checkbox" name="product-status" id="product-status"/></td>
<td><input type="text" name="send-quality" id="send-quality"/></td>
</tr>
<tr>

<td><input type="submit" name="submit" value="submit" class="btn btn-primary/"></td>
</tr>
</tbody>
</fieldset>

</form>
</div>

You can try this:
$(".table input[name='product-status']").change(function(){
if($(this).is(":checked")){
$(this).parents("tr:eq(0)").find("input[name='send-quality']").show();
}
else{
$(this).parents("tr:eq(0)").find("input[name='send-quality']").hide();
}

Using $(this).is(":checked"), see if the checkbox is checked. If it is checked, show the relevant input box. I have added a class hidden to each input box for this demo:
$('input[type=checkbox]').on('click', function() {
if ($(this).is(":checked"))
$(this).parents("tr:first").find('.hidden').show();
else
$(this).parents("tr:first").find('.hidden').hide();
})
.hidden {
display: none;
}

I'm trying to make ckecked to be showing me the first name of which is ckecked.
As shown in the picture
Or make a for which to cross the table and show me the ones that are checked
enter image description here

This should work for you. You will need to remove the extra comma (,) at the end.
$(function() {
$('.sus').click(function(e) {
var checkedNames = '';
var $things = $('.case:checked');
if($things.length > 0){
for (var i = 0; i < $things.length; i++) {
checkedNames += $($things[i]).closest('tr').find('td:first').text() + ',';
}
alert("checkeado " + checkedNames);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" class="btn btn-success sus">Success</button>
<div class="container">
<table class="table">
<thead>

<tbody>
<tr>

Javascript to Disable checkboxes in a table with variable rows

I have a table which can have variable # of rows. how can I disable all checkboxes at once?
<table border="1" class="myTable grid">
<tr align="center">
<td> </td>
<td>A</td>
</tr>
<tr align="center">
<td>1</td>
<td><input type="checkbox" name="cb1;1" value="1"></td>
</tr>
<td>2</td>
<td><input type="checkbox" name="cb2;1" value="1" checked></td>
</tr>
<tr align="center">
</table>

Here is a javascript only solution that disables all checkboxes in myTable.
document.getElementByClassName("myTable").querySelectorAll("input[type='checkbox']").disabled = true;

A jQuery solution would be:
$('.myTable input[type=checkbox]').attr('disabled', 'disabled');
Alternatively:
document.querySelectorAll('.myTable input[type=checkbox]').disabled = true;

Try utilizing a for loop to iterate NodeList returned by document.querySelectorAll(selectors) , set each [type=checkbox] element to disabled within for statement
var inputs = document.querySelectorAll("[type=checkbox]");
for (var i = 0; i < inputs.length; i++) {
inputs[i].disabled = true;
}
<table border="1" class="myTable grid">
<tbody>
<tr align="center">
<td> </td>
<td>A</td>
</tr>
<tr align="center">
<td>1</td>
<td>
<input type="checkbox" name="cb1;1" value="1">
</td>
</tr>
<td>2</td>
<td>
<input type="checkbox" name="cb2;1" value="1" checked>
</td>
</tr>
<tr align="center">
</tbody>
</table>
