Select a row from html table and send values onclick of a button

Question

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 Javascr

Answer 1

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());
    });
});
