I am able to use the following JS code to find if a checkbox is selected in a table row.

//selected checkbox  
  $(".select_checkbox input").on("change", function() {
  if (this.checked) {
    //alert("i am checked!"); 

   var selectedname = $(this).find('.name_row input').val();

alert(selectedname); 
}

});

But I am not able to extract the values of other field values in that row.

In the above code, I wanted to find the name value in that selected row.

I tried to use formula in a hidden field which is also not working.
