I have HTML table where I need to select a row and send its first cell ID to a button and onclick of the button send the selected value to a function in Javascript. How can I achieve this?

test.html :

<table id="table">
        <tr>
            <td>1 Ferrari F138</td>
            <td>1 000€</td>
            <td>1 200€</td>

        </tr>
        <tr>
            <td>2 Ferrari F138</td>
            <td>1 000€</td>
            <td>1 200€</td>

        </tr>
        <tr>
            <td>3 Ferrari F138</td>
            <td>1 000€</td>
            <td>1 200€</td>

        </tr>
    </table>
    <input type="button" id="tst" value="OK" onclick="fnselect()" />

test.js :

var table = document.getElementById('table'),
    selected = table.getElementsByClassName('selected');
table.onclick = highlight;
function highlight(e) {
    if (selected[0]) selected[0].className = '';
    e.target.parentNode.className = 'selected';
}
function fnselect(){
var $row=$(this).parent().find('td');
    var clickeedID=$row.eq(0).text();
    alert(clickeedID);
}

test.css :

td {border: 1px #DDD solid; padding: 5px; cursor: pointer;}

.selected {
    background-color: brown;
    color: #FFF;
}

This is a fiddle of my problem JSFIDDLE

I need to send the selected row's first cell value to a javascript function. But when the user selects a row and clicks on 'OK' button I should send the value to the function. How to do this?

$("#table tr").click(function(){
   $(this).addClass('selected').siblings().removeClass('selected');    
   var value=$(this).find('td:first').html();
   alert(value);    
});

$('.ok').on('click', function(e){
    alert($("#table tr.selected td:first").html());
});

  • I want to send the first cell value only after I click OK button. Not onclick of a row sir. That is where I am stuck. – user3201640 Jul 15 '14 at 05:56

    @PrasaanthNeelakandan, You have dynamically added elements in DOM. Try the below code. $(document).on('click', '#table tr', function(){ alert($(this).find('td:first').html()) }); Go through what is event delegation in jquery. Second one satisfies the event delegation. – RGS Feb 25 '16 at 17:34

You can access the first element adding the following code to the highlight function

$(this).find(".selected td:first").html()

    <html>
  <header>
         <style type="text/css">
       td {border: 1px #DDD solid; padding: 5px; cursor: pointer;}
       .selected {
                  background-color: brown;
                  color: #FFF;
                  }
          </style>
 </header>
        <body>
        <table id="table">
            <tr>
                <td>1 Ferrari F138</td>
                <td>1 000€</td>
                <td>1 200€</td>
            </tr>
            <tr>
                <td>2 Ferrari F138</td>
                <td>1 000€</td>
                <td>1 200€</td>
            </tr>
            <tr>
                <td>3 Ferrari F138</td>
                <td>1 000€</td>
                <td>1 200€</td>
            </tr>
        </table>
      <input type="button" id="tst" value="OK" onclick="fnselect()" />
    
    <script>
        var table = document.getElementById('table');
        var selected = table.getElementsByClassName('selected');
        table.onclick = highlight;
    
    function highlight(e) {
        if (selected[0]) selected[0].className = '';
        e.target.parentNode.className = 'selected';
    }
    
    function fnselect(){
        var element = document.querySelectorAll('.selected');
        if(element[0]!== undefined){ //it must be selected
         alert(element[0].children[0].firstChild.data);
        }
    }
  </script>
 </body>
</html>

There is only one member with the class 'selected' in this list (NodeList), it is the element[0]. children is a htmlcollection of the 3 <td>'s (inside the <tr>), children[0] ist the first <td> at place [0] and .data is its value. (firstChild is the complete string in quotes.) If you use the console it is easy to find the properties you can use.

This below code will give selected row, you can parse the values from it and send to the AJAX call. 

$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();            
});

In my case $(document).ready(function() was missing. Try this.

$(document).ready(function(){   
("#table tr").click(function(){
       $(this).addClass('selected').siblings().removeClass('selected');    
       var value=$(this).find('td:first').html();
       alert(value);    
    });
    $('.ok').on('click', function(e){
        alert($("#table tr.selected td:first").html());
    });
});
