Get row when checking checkbox in html table

HTML DOM solves your problem

<script type="text/javascript">
    function getRow(n) {
        var row = n.parentNode.parentNode;
        var cols = row.getElementsByTagName("td");
        var i=0;
        while (i < cols.length) {
            alert(cols[i].textContent);
            i++;
        }
    } 
</script>

<table>
    <tr>
        <td><input type="checkbox" onclick="getRow(this)"  /></td>
        <td>aaa</td>
        <td>bbb</td>
    </tr>
    <tr>
        <td><input type="checkbox" onclick="getRow(this)" /></td>
        <td>ccc</td>
        <td>ddd</td>
    </tr>
    <tr>
        <td><input type="checkbox" onclick="getRow(this)" /></td>
        <td>eee</td>
        <td>fff</td>
    </tr>
</table>

EDIT: this script will help you more, I think:

function getRow(n) {
    var row = n.parentNode.parentNode;
    var cols = row.getElementsByTagName("td");
    var i = 0;

    while (i < cols.length) {
        var val = cols[i].childNodes[0].nodeValue;
        if (val != null) {
            alert(val);
        }

        i++;
    }
}

You could try something like this:

HTML:

<table>
    <thead>
        <tr><th></th><th>Row Text</th></tr>
    </thead>
    <tr>
        <td><input type="checkbox" /></td>
        <td>Test</td>
    </tr>
    <tr>
        <td><input type="checkbox" /></td>
        <td>Test 2</td>
    </tr>
    <tr>
        <td><input type="checkbox" /></td>
        <td>Test 3</td>
    </tr>
</table>

JavaScript:

checkboxes = document.getElementsByTagName("input"); 

for (var i = 0; i < checkboxes.length; i++) {
    var checkbox = checkboxes[i];
    checkbox.onclick = function() {
        var currentRow = this.parentNode.parentNode;
        var secondColumn = currentRow.getElementsByTagName("td")[1];

        alert("My text is: " + secondColumn.textContent );
    };
} 

JSFiddle: http://jsfiddle.net/markwylde/wzPHF/1/

if your select is in td directly, try the following:

sel.onclick = function(){
  row = this.parentNode.parentNode
  //then what you need
}

Note that first you have to find sel with either document.getElementById() or document.getElementsByTagName()

Also you may need to handle onchange event instead of onclick

This will give you content of row directly(all td in tr) HTML:

<table>
    <tr id="tr1">
        <td>
            <input type="checkbox" value="chkbox1" id="chk1">
        </td>
        <td>
            Lorem ipsum text
        </td>
    </tr>
    <tr id="tr2">
        <td>
            <input type="checkbox" value="chkbox2" id="chk2">
        </td>
        <td>
            Lorem ipsum text
        </td>
    </tr>
</table>

Jquery:

$(document).ready(function(){
    $('#chk1, #chk2').on('change',function(){
            if($('#chk1').prop('checked') || $('#chk2').prop('checked'))
            {
                var ids=$(this).parent().parent().html();
                alert(ids);
            }
            else
            {
            }
        });
    })

if you're new :

onChange EVENT of the checkbox will call the function that i named "checking"

it will send "This.checked", which means, will send True or false to the function "checking", Then i go in the function get that True or False that was sent, and put it in a variable i called "temp".

HTML: onchange="checking(this.checked)" <--- sending out : "This.checked" ( This = the object that creates the Event onchange, and .checked, is the propriety) you could even send multiple info like this : onchange="checking(this.checked,this.id)" and so on.

JAVASCRIPT :function checking(temp) <--- this is how it gets the "this.checked" in HTML, and put it in the variable temp. to receive multiple infos : function checking(temp,temp2) and so on.(name it like you want)

then i run a 'IF' with the variable "temp" and if the value of it = true, then do alert.

Hope it helps, think about it and work it so it fits what you need !

HTML :

<table>
        <tr>
                <td>
                        <input type="checkbox" value=""onchange="checking(this.checked)">
                </td>
                <td>
                        <label>Something Here</label>
                </td>
        </tr>
</table>

JAVASCRIPT :

            function checking(temp)
            {

                if(temp == true)
                {
                    alert("Checkbox is checked");
                }
                else
                {
                    alert("Checkbox is NOT checked");
                }
            }
