Retrieving column values from a table by clicking row with jquery and html

I'm using html5 and jquery to set up a dynamic table, until then I can add the elements to the table without problems, but I can not retrieve the value of its columns. so I have the following questions:
How can I recover the table data by clicking the ROW?
Should I always use the data-name, id for example as in the first
line ?
$(document).on("change", "#TabClientesAdicionados", function(e) {
alert('?');
});
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<hr>
<table id="TabClientesAdicionados" class="table table-hover">
<thead>
<tr>
<th> ID </th>
<th> Name </th>
<th> Actions </th>
</tr>
</thead>
<tbody>
<tr>
<td data-id="Bruno">1</td>
<td data-nome="Bruno">Bruno</td>
<td>Details</td>
</tr>
<tr>
<td>2</td>
<td>Josep</td>
<td> Details </td>
</tr>
</tbody>
</table>

How can I recover the table data by clicking the ROW?
You can bind the click event to your TR elements and get the information.
Should I always use the data-name, id for example as in the first line?
Yes, because you don't want the parsed HTML to manipulate data. The data attributes are a better approach to keep related data (no HTML) to DOM elements.
Look at this code snippet
This approach binds the click event to TR elements
$('#TabClientesAdicionados tbody tr').click(function() {
var data = { name: '', id: '' };
$(this).children('td').each(function() {
var name = $(this).data('nome');
if (name) {
data.name = name;
}
var id = $(this).data('id');
if (id) {
data.id = id;
}
});
console.log(data);
});
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<hr>
<table id="TabClientesAdicionados" class="table table-hover">
<thead>
<tr>
<th> ID </th>
<th> Name </th>
<th> Actions </th>
</tr>
</thead>
<tbody>
<tr>
<td data-id="Bruno_1">1</td>
<td data-nome="Bruno">Bruno</td>
<td>Details</td>
</tr>
<tr>
<td>2</td>
<td>Josep</td>
<td> Details </td>
</tr>
</tbody>
</table>

I would do as the following snippet.
You need to bind the event to the row tr ant then get each of its children.
By adding a data attribute you could set a column name. This could also help if you eventually needed to extract the value of an specific cell.
Incidentally you could also add a second data attribute named like data-value or something similar- This in case you are worried that your parsed html content might cause you trouble with the values.
$(document).ready(function() {
$("#mytable").on('click', 'tr', onCellClick);
//Bind the event to the table row
function onCellClick() {
let row = $(this); //get the jquery Object for the row
let rowValues = {}; //An empty object to hold your data
let temp;
//extract the value of every cell in the row
//Doing it this way gives you flexibility on the amount of colums you have
row.find('td').each(function(item) {
temp = $(this);
rowValues[temp.data('column')] = temp.text();
//this could be changed to
//rowValues[temp.data('column')] = temp.data('value);
//if you desire to use a separate data-value property
});
console.log(rowValues);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table style="width:100%" id="mytable">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
</tr>
<tr>
<td data-column="name" data-value="Jill">Jill</td> <!-Adding value property-->
<td data-column="lastname">Smith</td>
<td data-column="age">50</td>
</tr>
<tr>
<td data-column="name">Eve</td>
<td data-column="lastname">Jackson</td>

Changing the <td> element of a table using DOM

I have been learning about DOMs lately and have been stuck on a problem for days. For some reason, I cannot change the contents of a html table. I have been looking at w3 schools HTML and using DOM to change the table element.
Here is the code for the table :
<div id="courseSummaryContainer" class="tab">
<table cellspacing="0" class="summaryTable courseSummary smallFontTable" summary="Health Care by province">
<thead><tr>
<th>Name</th>
<th>Description</th>
<th>Date of entry</th>
<th>Rating</th>
<th>Grade</th>
<th>Submission entry type</th>
</tr></thead>
<tbody>
<tr class="row-even">
<td>Illinois</td>
<td>Online system</td>
<td>201602</td>
<td>0100</td>
<td>5</td>
<td>Final</td>
</tr>
<tr class="row-odd">
<td>Alabama</td>
<td>Regional area health</td>
<td>201606</td>
<td>0100</td>
<td>7</td>
<td>Final</td>
</tr>
<tr class="row-even">
<td>Illinois</td>
<td>Online system</td>
<td>201602</td>
<td>0100</td>
<td>5</td>
<td>Final</td>
</tr>
</tbody>
</table>
</div>
What I have been trying to do is change the names of the states and their values. To do so, I have been trying to access the <td> element.
To change the contents, I tried the following:
Say for example want to change "Illinois" to "Georgia" I tried the following
document.getElementById("table.summaryTable.courseSummary.sm‌allFontTable").rows[‌2].cells;
x[1].innerHTML = "Georgia";
I am not sure what I am doing wrong however the console keeps giving errors all the time stating the values are null.
Can somebody please offer their guidance?

Use document#querySelector. In this case a simple selector can be .row-even > td:first-child because you only have one .row-even.
How can you be more specific?
If you've got multiple .row-even, by using tbody > tr:nth-child(1) > td:first-child.
If you have multiple tables with .row-even, you can add the id of the container #courseSummaryContainer .row-even > td:first-child or the class of the table .courseSummary .row-even > td:first-child.
var td = document.querySelector('.row-even > td:first-child');
td.innerText = 'Georgia';
<div id="courseSummaryContainer" class="tab">
<table cellspacing="0" class="summaryTable courseSummary smallFontTable" summary="Health Care by province">
<thead><tr>
<th>Name</th>
<th>Description</th>
<th>Date of entry</th>
<th>Rating</th>
<th>Grade</th>
<th>Submission entry type</th>
</tr></thead>
<tbody>
<tr class="row-even">
<td>Illinois</td>
<td>Online system</td>
<td>201602</td>
<td>0100</td>
<td>5</td>
<td>Final</td>
</tr>
<tr class="row-odd">
<td>Alabama</td>
<td>Regional area health</td>
<td>201606</td>
<td>0100</td>
<td>7</td>
<td>Final</td>
</tr>
</tbody>
</table>
</div>

You are not getting the right element in the DOM, if you are going to use the function: "getElementById", you need to pass it the id of the element that you want to have, like:
html:
<div id="courseSummaryContainer" class="tab">
<table id="myTable" cellspacing="0" class="summaryTable courseSummary smallFontTable" summary="Health Care by province">
//... Table content
</table>
</div>
js:
document.getElementById("myTable").rows[‌2].cells;

How to take the Dynamic-table cell value in JavaScript

This is a table of one of my jsp page. I want to take the selected value of the column empId for a javascript method.
<table class="table table-bordered">
<thead>
<tr>
<th>Employee ID</th>
<th>Employee Name</th>
<th>Casual Leave Balance</th>
<th>Annual Leave Balance</th>
<th>Sick Leave Balance</th>
</tr>
</thead>
<tbody>
<c:forEach var="leavebalances" items="${LeaveAllBalanceList}">
<tr>
<td><dev class="correct" name="empId" onclick="selectempId(this)"> ${leavebalances.empId}</dev></td>
<td>${leavebalances.empId}</td>
<td>${leavebalances.casual}</td>
<td>${leavebalances.annual}</td>
<td>${leavebalances.sick}</td>
</tr>
</c:forEach>
</tbody>
</table>
my javascript code segment
function selectempId(emp){
alert(emp);
}
But It (onclick) doesn't work. There are only methods to get selected values of dynamic dropdowns. Please tell me how to do this.
Thank you.

<dev class="correct" name="empId" onclick="selectempId(this)"> ${leavebalances.empId}</dev>
You don't need ()

You can pass value to javascript. But I don't know the dev tag in html. I think it is div.
<td><div class="correct" name="empId" onclick="selectempId(${leavebalances.empId})"> ${leavebalances.empId}</div></td>
Or you can pass to td's onclick action.
<td onclick="selectempId(${leavebalances.empId})">${leavebalances.empId}</td>

Here, my problem was being unable to pass td's values to javascript function, because there were no unique id's assigned for required td tags (dynamic table). So I gave dynamic ids.
<c:forEach var="leavebalances" items="${LeaveAllBalanceList}">
<tr>
<td id ="${leavebalances.empId}" class="correct" name="empId" onclick="selectEmpId(this.id)">${leavebalances.empId}</td>
<td>${leavebalances.empId}</td>
<td>${leavebalances.casual}</td>
<td>${leavebalances.annual}</td>
<td>${leavebalances.sick}</td>
</tr>
</c:forEach>
/////////////////////javascript function///////////////////////////////
function selectEmpId(val) {
alert(val);
}

Access each individual custom cell with Angular bootstrap calendar

I'm working on an app where I need a calendar skeleton (without the standard events) so I can put tables inside each cell, so I'm using the Angular Bootstrap Calendar with custom cell templates. I have everything working fine in terms of displaying the custom template in each cell and being able to navigate between months, but I need to be able to access each individual day and make data available in each one.
Here's my controller:
(function() {
angular.module('myApp')
.controller('calendarController', function($scope, $state, moment, calendarConfig) {
var vm = this;
calendarConfig.templates.calendarMonthCell = 'views/calendar/dayTemplate.html';
calendarConfig.dateFormatter = 'moment';
vm.events = [];
vm.calendarView = 'month';
vm.viewDate = moment().startOf('month').toDate();
$scope.$on('$destroy', function() {
calendarConfig.templates.calendarMonthCell = 'mwl/calendarMonthCell.html';
});
});
})();
and the corresponding dayTemplate.html:
<div class="cal-month-day">
<span
class="pull-right"
data-cal-date
ng-click="calendarCtrl.dateClicked(day.date)"
ng-bind="day.label">
</span>
<!--
<small style="position: absolute; bottom: 10px; left: 5px">
There are {{ day.events.length }} events on this day
</small> -->
<!-- <table class="table table-bordered table-condensed"> -->
<table class="table table-bordered table-condensed">
<thead>
<tr>
<td>Station</td>
<td>Position</td>
<td>Name</td>
</tr>
</thead>
<tbody>
<tr>
<td rowspan="3" align="top">1</td>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
</tbody>
</table>
<table class="table table-bordered table-condensed">
<tbody>
<tr>
<td rowspan="3" align="top">2</td>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
</tbody>
</table>
<table class="table table-bordered table-condensed">
<tbody>
<tr>
<td rowspan="3" align="top">3</td>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
<tr>
<td>Position</td>
<td>Name</td>
</tr>
</tbody>
</table>
</div>
When using the calendar as it normally is used, you can see that the days.events object has the data, but I need to access that object, or create my own so I can fill my tables. Is there a simple (or even not so simple) way to do that?
Thanks.
UPDATE: I just went back and read the docs and noticed this
An optional expression that is evaluated on each cell generated for
the year and month views. calendarCell can be used in the expression
and is an object containing the current cell data which you can modify
(see the calendarHelper service source code or just console.log it to
see what data is available). If you add the cssClass property it will
be applied to the cell.
Due to my lack of knowledge, I'm not understanding how to use this to override. If I console.log calendarCell in my calendarController it chokes because that object doesn't exist. If I'm reading this correctly, I can intercept the cell data and modify, but I'm not understanding how.

In this case, RTFM turned out to be the correct answer. Per the docs:
<div ng-controller="CellModifierCtrl as vm">
<ng-include src="'calendarControls.html'"></ng-include>
<mwl-calendar
events="vm.events"
view="vm.calendarView"
view-date="vm.viewDate"
cell-modifier="vm.cellModifier(calendarCell)">
</mwl-calendar>
</div>
goes with this in the controller:
vm.cellModifier = function(cell) {
console.log(cell);
if (cell.label % 2 === 1 && cell.inMonth) {
cell.cssClass = 'odd-cell';
}
cell.label = '-' + cell.label + '-';
};
and voila!, you have access to the data. I'm still trying to figure out how to pass additional data into the function, but I'll open a separate question for that.

Class="ng-hide" get appended automatically though I am using ng-show with correct syntax

I need to show/hide tr tag of a table as per the scope value in the controller. I have written the code as shown below but class="ng-hide" gets appended everytime with tr tag automatically though I have declared my ng-show with correct syntax.
<div ng-show="IsParentExist">
<table>
<thead>...</thead>
<tbody>
<tr ng-show="noValueExist">
<span>There are no records to show here..</span>
</tr>
<tr ng-repeat....>
<td> </td>
</tr>
</tbody>
</table>
</div>
Here is a problem when it gets rendered in DOM as below
<div ng-show="IsParentExist">
<span>There are no records to show here..</span>
<table>
<thead>...</thead>
<tbody>
<tr class="ng-hide" ng-show="noValueExist">
</tr>
<tr ng-repeat....>
<td> </td>
</tr>
</tbody>
</table>
</div>
I have assigned the scope variable in controller as below
$scope.noValueExist = true;

Until you set the value of noValueExist as true in controller, angular sets the class as ng-hide by default.Add this line in controller.
$scope.noValueExist = true;

Try replacing ng-show="noValueExist" by ng-hide="!noValueExist"
<tbody>
<tr ng-hide="!noValueExist">
<td>There are no records to show here.</td>
</tr>
<tr>
<td></td>
</tr>
</tbody>
In your controller, initialize your value.
$scope.noValueExist = false;
And when you need to show your <tr> element set this value to true.
$scope.noValueExist = true;
I hope this will help you.

As user #cst1992 mentioned the issue was with span was not wrapped in .

The span is getting misplaced because it is not supported inside 'tr' tag.
You need to use 'td' tag to show content inside table.
After replacing 'span' with 'td' tag,it gets rendered in DOM as below.
<div ng-show="IsParentExist" class="ng-hide">
<table>
<thead>
<tr><th>a</th>
<th>b</th>
</tr></thead>
<tbody>
<tr ng-show="noValueExist" class="ng-hide">
<td>There are no records to show here.</td>
</tr>
<tr>
<td></td>
</tr>
</tbody>
</table>
</div>
