How to add listener to table column

I want to add listener to the html table column So that when I click the so called visualized table column, I want to perform something using js. consider this:
<table>
<thead>
<tr>
<th>name</th>
<th>lastname</th>
</tr>
</thead>
<tbody>
<tr>
<td>Guga</td>
<td>Nemsitsveridze</td>
</tr>
<tr>
<td>Giorgi</td>
<td>Beshidze</td>
</tr>
</tbody>
</table>
Now when I click the lastname cell (I mean the one of the following elements: <th>lastname</th>, <td>Nemsitsveridze</td>, <td>Beshidze</td>) I want to perform something using js.
The solution I was thinking about is to assign some kind of class attribute to each element of the lastname cell and add the same event listener to them independently, but I'm not sure if it is the only solution to this problem.
If anyone has an idea how to achieve this goal, please, answer the question.
Thanks in advance.

In order to execute something when a column is clicked, you can add one event listener to the whole table and then check which column was clicked, then execute some code.
Using window.event.target.cellIndex you can access the cell index.
Using window.event.target.parentNode.rowIndex you can access the row index.
document.getElementById('myTbl').addEventListener('click', function(event)
{
var col = window.event.target.cellIndex;
var row = window.event.target.parentNode.rowIndex;
if (col==1){
alert('Col index is: ' + col + '\nRow index is: ' + row);
}
});
table, td {
border: 1px solid black;
}
<table id="myTbl">
<thead>
<tr>
<th>name</th>
<th>lastname</th>
</tr>
</thead>
<tbody>
<tr>
<td>Guga</td>
<td>Nemsitsveridze</td>
</tr>
<tr>
<td>Giorgi</td>
<td>Beshidze</td>
</tr>
</tbody>
</table>

How to search in table based on specific column value?

I need to implement a search box in html table using drop down, so that I can search the data by specific column name heading.
<table>
<thead>
<tr>
<th>Fruit</th>
<th>Color</th>
</tr>
</thead>
<tr>
<td>Apple</td>
<td>Green</td>
</tr>
<tr>
<td>Grapes</td>
<td>Green</td>
</tr>
<tr>
<td>Orange</td>
<td>Orange</td>
</tr>
</table>
I got a Fiddle but this doesn't work in eclipse.

You can write simple script that will add a CSS class for proper column and column values. For example:
$("tr:first-child").addClass('fruits');
(you can add custom class like '.fruits' for Nth column, not only first-child, its only an example)
then you can write simple custom filter (searching for fruit with 'Z' letter in name) like:
var resultsOfSearchingFruitsWithZLetter = [];
$.each($('.fruits'), function(val) {
if(val.val().indexOf('z') > -1) {
resultsOfSearchingFruitsWithALetter.push(val.val());
}
});

Add table row with jQuery before button

I have this table, and I want to add Rows up the button, in the same rowId. For example, on clicking the Add Row 1 button, i want to add a row in row1, under "Some content 1", and so on.
<table id="table1">
<thead>
<th>Heading 1</th>
<th>Heading 2</th>
</thead>
<tbody>
<tr id="row1">
<td>Some content 1<td>
<td><button id="addButton1">Add Row 1</button><td>
</tr>
<tr id="row2">
<td>Some content 2<td>
<td><button id="addButton2">Add Row 2</button><td>
</tr>
<tbody>
</table>
This is the script I use so far:
$("#addBtn").on("click", function () {
$("#table1 tbody").append("<tr><td>1</td><td>1</td></tr>");
});
This is adding rows at the end of the table. How can I add rows in between, in the same section, using jQuery?

Try to use .closest() along with .after() to achieve what you want, and you should use id starts with selector in this context or you can add one common class for all of that buttons and use that as a selector.
$("[id^=addButton]").on("click", function () {
$(this).closest('tr').after("<tr><td>1</td><td>1</td></tr>");
});
Side Note: I have edited some of your ugly html in order to make your code valid
DEMO

You can do like this.
$("#table1 button").on("click", function () {
$(this).parents('tr').after("<tr><td>1</td><td>1</td></tr>");
});

Table row hover, background change and click but have some child cells in the row have different properties

<table>
<tr>
<th>#</th>
<th>Name</th>
<th>Surname</th>
</tr>
<tr onmouseover="ChangeColor(this, true);"
onmouseout="ChangeColor(this, false);"
onclick="DoNav('go.html');">
<td>1</td>
<td>John/td>
<td>Dump</td>
</tr>
</table>
Javascript:
function ChangeColor(tableRow, highLight)
{if (highLight)
{tableRow.style.backgroundColor = '#F5FFDB';}
else
{tableRow.style.backgroundColor = '';}}
function DoNav(theUrl)
{document.location.href = theUrl;}
I use the following structure to draw the table. When I hover on a row it changes the background and anywhere I click on the row it will jump to the url. What I'm trying to do is have some id identifier (that maybe goes into <td>) which basically tells certain columns in a row to behave differently. Namely this is what I'm looking for:
<table>
<tr>
<th>#</th>
<th>Name</th>
<th>Surname</th>
</tr>
<tr>
<td id="hover_go_style_1">1</td>
<td id="hover_go_style_1">John</td>
<td id="hover_go_style_2">Dump</td>
</tr>
</table>
Any ideas?
EDIT:
I forgot to mention... the id="hover_go_style_1" would take me to one url and id="hover_go_style_2" would take me to another url. That's the "difference". As it is now with onClick the whole row takes me to one url, but in essence im trying to isolate cells. Not sure how to explain this better.

You should be using CSS for your hover color, it's much simpler there. Your click event can be much nicer hooked up and handled completely in your JavaScript also. I've added a data-url (HTML5-compatible) attribute to your row to define the URL.
jsFiddle
HTML
<table>
<tr>
<th>#</th>
<th>Name</th>
<th>Surname</th>
</tr>
<tr data-url="go.html">
<td>1</td>
<td>John</td>
<td>Dump</td>
</tr>
</table>
JS
$('tr[data-url]').click(function () {
window.location.href = $(this).attr('data-url');
});
CSS
tr:hover td {
background-color:#F5FFDB;
}
/* Style the third column differently */
tr:hover td:nth-child(3) {
background-color:#F00;
}

Copy cell value from table to textbox

I have the following table. I want to copy Id value on the seleced row to the text box. If I click on link "Select" in the first row the text box value will 0001.
If the table needs modification to get result better and faster, please leave your suggestion.
<div>
<input id="selectedId" type="text" />
</div>
<table cellspacing="1" class="tablesorter" id="nameList">
<thead>
<tr>
<th class="header">Name</th>
<th class="header">Id</th>
<th class="header">Gender</th>
<th>Select</th>
</tr>
</thead>
<tbody>
<tr>
<td>Akom Smith</td>
<td>0001</td>
<td>M</td>
<td>Select</td>
</tr>
<tr>
<td>Amara Sahara</td>
<td>0002</td>
<td>F</td>
<td>Select</td>
</tr>
<tr>
<td>John Lache</td>
<td>0003</td>
<td>M</td>
<td>Select</td>
</tr>
</tbody>
</table>

try this,
$('a.click-to-select').click(function() {
var id = $(this).closest('tr').find('td').eq(1).text();
$('#selectedId').val(id);
return false;
});​
simple cool demo
added notes for the comment below.
$('a.click-to-select').click(function() {
var id = $(this).closest('tr').find('td.id').text();
$('#selectedId').val(id);
return false;
});​
updated demo

Well, you know your key is the second td in the row. You can use the :nth-child selector like this:
<script type="text/javascript">
var getUniqueId = function() {
return $('td:nth-child(2)').text();
}
</script>
Of course you need a way to identify the correct , but I assume the code is supposed to be called from each and there you can use the parent selector.
Otherwise I'd put an id attribute in each row to make selecting easier.
